摘要： A hand held seed planter includes a tubular body and a pair of ground-opening jaws pivotally carried on one end of the body. A seed hopper is slidably mounted on the other end of the body and a ground engaging collar is carried on the one end, surrounding the jaws and mounted for sliding movement on the tubular body. When the soil collar is placed on the ground and a downward force applied to the handle attached to the hopper, the jaws are moved downward into the soil and create a seed opening in the soil. Adjustable pins on the collar control the depth of the opening. At the same time, a seed scoop recess, carrying a seed, is brought into alignment with an opening in a tube which extends through the hopper. A seed is then transferred into the tube, passing through the tubular body and between the jaws, to be planted in the seed opening.In one embodiment of the invention, the jaws are operated by upward movement of the soil collar, while in another embodiment, the jaws are operated by rollers carried on an internal jaw actuating tube which contacts cams formed in the inside surfaces of the jaws.
摘要翻译：手持种子播种机包括管状体和枢转地承载在身体的一端上的一对接地开口爪。种子料斗可滑动地安装在主体的另一端，并且地面接合套环在一端承载，围绕夹爪并安装成用于在管状体上的滑动运动。当土套环放置在地面上并向附着在料斗上的手柄施加向下的力时，将钳口向下移动到土壤中，并在土壤中形成种子开口。衣领上的可调销钉控制开口的深度。同时，携带种子的种子勺凹槽与延伸穿过料斗的管中的开口对齐。然后将种子转移到管中，通过管状体和钳口之间，种植在种子开口中。

摘要： A relatively compact and lightweight planting and fertilizing apparatus is attached to a small garden tractor by a universal hitch which restricts lateral movement between the two. The apparatus is spring biased downwardly to assure firm contact with the ground, and can be raised above the ground by a single lever. The lever carries the biasing spring, and cams lifting bearings on the lever against a lifting plate on the apparatus. The fertilizer is fed by an axially adjustable feed gear rotated by a ground engaging wheel on the apparatus. The feed gear is biased by an adjusting spring against a threaded adjusting knob which sets the axial position of the feed gear.
摘要翻译：相对紧凑和轻便的种植和施肥设备通过通用钩挂连接到小型园林拖拉机，限制了两者之间的横向移动。该装置被向下偏压以确保与地面的牢固接触，并且可以通过单个杠杆升高到地面上方。杠杆承载偏置弹簧，凸轮将杠杆提升到装置上的升降板上。肥料由在装置上由接地轮转动的可轴向调节的进给齿轮供给。进给齿轮通过调节弹簧抵靠螺纹调节旋钮偏置，螺旋调节旋钮设定进给齿轮的轴向位置。

摘要： A hand-held, power driven cultivator includes a housing and cultivator blades which rotate about axes oblique to the vertical axis of the cultivator, the blades extending generally in planes which converge beneath the housing. The cultivator is driven by an electrical motor and has a power train which includes a speed reduction gear arrangement. The cultivator blades may overlap slightly as they rotate and may be formed of hardened metal or plastic. The housing of the cultivator is provided with a skirt which extends outwardly and downwardly about the sides and rear of the housing. The skirt is provided with lower depending side shield portions and a rear rake or spreading portion. The rear rake or spreading portion is formed with notches or teeth to smooth and spread cultivated dirt.
摘要翻译：一种手持动力驱动的耕耘机包括围绕垂直于耕耘机的垂直轴线的轴线旋转的壳体和耕耘机叶片，叶片大致在会聚在壳体下方的平面中延伸。耕耘机由电动机驱动，并具有包括减速装置的动力传动系。耕耘机叶片可以在其旋转时稍微重叠，并且可以由硬化的金属或塑料形成。耕耘机的外壳设置有一个围绕外壳的侧面和后部向外和向下延伸的裙部。裙部设置有下悬垂侧屏蔽部分和后耙或扩展部分。后耙或铺展部分形成有凹口或齿，以平滑和扩展耕种的污垢。
