Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seed harvesting technology, and in particular to a device for harvesting milkvetch seeds. Background Technology
[0002] Milk vetch, also known as clover, is a biennial herbaceous plant belonging to the genus Astragalus in the legume family. It has many branches covered with sparse white hairs, odd-pinnate compound leaves with obovate or elliptic leaflets, nearly glabrous on the upper surface and sparsely covered with white hairs on the lower surface. The leaves have short petioles and are borne in racemes with purplish-red or orange-yellow corollas. The fruit is a linear-oblong, slightly curved pod with a short beak, and is black. The seeds are kidney-shaped and chestnut-brown. Flowering occurs from February to June, and fruiting from March to July, with a growing period of approximately 210-230 days.
[0003] Current milkvetch seed harvesting devices may cause the milkvetch to tip over during harvesting, resulting in the seeds falling to the ground. This prevents the harvesting device from accurately contacting the milkvetch seeds, thus affecting the harvest yield.
[0004] Therefore, in view of this situation, there is an urgent need to design and produce a milkvetch seed harvesting device to meet the needs of practical use. Utility Model Content
[0005] The purpose of this invention is to provide a milkvetch seed harvesting device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a milkvetch seed harvesting device, comprising an electric cutter for milkvetch seed harvesting and a first prying member, a connecting plate fixedly connected to the lower side of the first prying member, a first fixing plate fixedly connected to the lower side of the connecting plate, a first motor mounted on the side of the first fixing plate, a first rotating shaft fixedly connected to the output end of the first motor, a second fixing plate fixedly connected to the side of the first rotating shaft, a second motor mounted on the upper side of the second fixing plate, a second rotating shaft fixedly connected to the output end of the second motor, and a second prying member fixedly connected to the end of the second rotating shaft away from the second fixing plate.
[0007] Preferably, the end of the first rotating shaft away from the first fixed plate is rotatably connected to a first outer shell, and a second outer shell is installed on the upper side of the first outer shell.
[0008] Preferably, a third outer shell is installed on the side of the second outer shell, and a first telescopic rod is installed on the upper side of the third outer shell.
[0009] Preferably, a first movable plate is fixedly connected to the extended end of the first telescopic rod, and a second telescopic rod is installed on the side of the first movable plate.
[0010] Preferably, the extended end of the second telescopic rod is fixedly connected to a second movable plate, and the second movable plate is installed with the electric cutting machine.
[0011] Preferably, a caster wheel is installed on the lower side of the first outer shell, and a storage box is installed on the upper side of the second outer shell.
[0012] Preferably, a pump is installed on the side of the second outer casing, and the side of the first pusher is fixedly connected to the inner wall of the third outer casing.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] The milkvetch seed harvesting device uses a first motor to drive a first rotating shaft to rotate, which in turn drives a second fixed plate and a second lever to rotate. Then, a second motor is started to drive the second rotating shaft and the second lever to rotate, straightening the tilted milkvetch and harvesting the mature milkvetch seeds, preventing the mature seeds from falling to the ground and causing the cutting blades to be unable to cut and harvest them.
[0015] After the milkvetch is straightened, it is cut using an electric cutter. Once cut, the milkvetch seeds are collected using a pump and placed in a storage box. Attached Figure Description
