摘要： PROBLEM TO BE SOLVED: To provide a fertilizer applicator that can smoothly transport fertilizer through the fertilizer transportation pipes and recover the fertilizer from its recovering parts and can distribute the fertilizer to plural positions in the crop field. SOLUTION: In the fertilizer applicator, the fertilizer in the hopper 31 is conveyed from a plurality of the fertilizer feeders 32 arranged in parallel on the left and right sides of the machine body via individual pipes 38 to individual distributors. The fertilizing air chamber 34 that feeds the pressurized air flow from the blower to the fertilizer-transferring pipe 38 is extended in the transverse direction on the front side of the fertilizer feeders 32. The blower feeds the pressurized air flow into the fertilizer-recovering pipes that extend long in the transverse direction and can feed the fertilizer in the hopper whereby the fertilizer can be recovered outside the machine and the fertilizer-recovering pipe 36 is set on the front side of the fertilizer feeders 32.

摘要： PROBLEM TO BE SOLVED: To streamline a treatment for cutting the residual stems of tobacco. SOLUTION: The device 2 for cutting the residual stems of tobaccos is connected to the front portion of the body of a tractor 1, and the tractor 1 is driven along the ridge of the tobacco residual stems. The tobacco residual stems having a total length of 100 cm are cut into 25 cm cut pieces with four pairs of right and left rotary blades 8, 8... attached to right and left cutting blade shafts 5, 5 at positions mutually shifted in the vertical direction, and then released into grooves 13 on both the sides of the ridge. A tilling work is once performed with a rotary tiller along the ridge 12 to release the tilled soil into the grooves 13 on both the sides, thus burying the released cut residual stems in the soil. Since the right and left cutting blade shafts 5, 5 are forward inclined so that the upper portions of the right and left cutting blade shaft 5, 5 are placed on the front sides, the tobacco residual stems are sequentially cut with the right and left rotary blades 8, 8,... from the upper side to the lower side, the cutting loads of the cutting device can be reduced. The right and left cutting blade shafts 5, 5 are mutually pivotally disposed in such a laterally inclined posture that the upper portions and the lower portions of the right and left cutting blade shafts 5, 5 are disposed at places near to the center and at both the right and left sides, respectively. Thereby, the outer peripheral portions of the upper side blades of the right and left rotary blades 8, 8 attached to the right and left cutting blade shafts 5, 5 at positions shifted in the vertical direction are much overlapped each other, while the outer peripheral portions of the lower side blades are a little overlapped. Thus, the loads of the cutting device for cutting the hard lower portions of the residual stems can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a method for seeding capable of strengthening an establishment and reducing a lodging degree by carrying out a sowing at a deep position on the basis of the surface of a field and having a promoting effect on germination and raising of seedlings by shallowly covering seeds with soil. SOLUTION: A protruded row part is formed along a central part in a furrow made on the surface of a field by a wide furrow opener with advancement. In the following process, while the protruded row part is dug and removed by the furrow opener to form a seedling furrow 24, the soil of the furrow is piled at both the sides to prepare soil 25 for soil covering. Seeds are fed from a subsequent seeding pipe to the seeding furrow 24 to carry out a sowing. In a final process, only the seeding furrow 24 after sowing is covered with the soil 25 for soil covering.

摘要： PROBLEM TO BE SOLVED: To provide a seedling transplanter, capable of simplifying a mechanism for carrying seedling trays for pot seedlings along a prescribed seedling tray- carrying route, facilitating the maintenance and improving the carrying accuracy. SOLUTION: A mechanism for carrying seedling trays T along a seedling tray-carrying route 31 is formed so as to be switched to a state for carrying a seedling tray T or to a state capable of taking out the seedling tray T. In the state for carrying a seedling tray T, the seedling tray T is carried by nipping a part of the seedling tray T with a pair of carrying rollers 60, 61 arranged in the direction crossing a seedling tray-carrying direction and then rotating and driving a pair of the carrying rollers 60, 61 in a prescribed direction. In the state capable of taking out the seedling tray T, the seedling tray T can be taken out from the seedling tray-carrying route 31 without nipping a part of the seedling tray T with a pair of the carrying rollers 60, 61.

摘要： PROBLEM TO BE SOLVED: To solve a problem that an operator informed of the clogging of a fertilizing nozzle with a fertilizer applicator by an alarm device must stop a fertilizing work and remove the clogged fertilizer applicator by a hand work in usual fertilizers. SOLUTION: In this fertilizer applicator, plural rows of fertilizing nozzles 4 for applying a fertilizer fed from a fertilizer tank 2 on a traveling vehicle 1 to a farm field by a compressed transporting air blown from an air chamber 3 are arranged and installed. A clogging sensor S for detecting clogging of the fertilizer is installed to the fertilizing nozzle, while an actuator 5 for regulating the air flow is installed in the upstream of the air flow. A controlling means C which controls the actuator 5 to send compressed wind stronger than that of the compressed transporting air depending on the detected information of the clog sensor S is installed. A control means for controlling the actuator 5 is installed to the fertilizing nozzle having a happening of fertilizer clogging to intermittently blow a compressed wind stronger than that of the compressed transporting air.
