Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology and relates to a device for fixed-distance sowing of beans. Background Technology

[0002] When planting soybeans, mung beans, and other legumes, the soil in the area to be planted needs to be turned over first to loosen the soil. Planting holes are then dug according to a certain planting spacing. Bean seeds are then placed into the planting holes, and finally, soil is covered to bury the seeds. A new type of integrated legume planting machine includes a mobile frame. Along its walking direction, the frame is equipped with a soil-tilling mechanism, a ditching mechanism, a sowing mechanism, and a soil-covering mechanism. The soil-tilling mechanism includes a cutter head, which rotates via a motor as the frame moves forward to turn the soil. The ditching mechanism includes ditching blocks, which move forward with the frame to create planting furrows and accumulate soil on both sides. The sowing mechanism includes a bean storage bin, a bean distribution bin, and a bean distribution wheel, which places bean seeds into the planting furrows at set intervals as the frame moves forward. The soil-covering mechanism includes a soil-covering disc. This all-in-one machine mainly uses the rotation of the bean separating wheel to sow beans into the planting furrow at certain intervals. However, the beans are of different sizes. If the beans are too large, the bean separating trough is too small and will squeeze and cut off the beans, thus damaging them. In severe cases, it will cause the bean separating trough to become blocked. If the beans are too small, as one bean enters the bean separating trough, part of another bean also enters the bean separating trough. At this time, the bean separating wheel will squeeze and cut off part of the bean that has entered, causing damage to the bean. Utility Model Content

[0003] This utility model provides a fixed-distance bean planting device to solve the problem of bean damage caused by the different sizes of beans when the beans are separated in an existing integrated bean planting machine.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a bean separating device with a bean storage bin at the top, the bean separating device including a bean pressing frame, a bean pressing plate, a cam, a rocker arm, a connecting rod, a clamping plate and a bean discharging pipe, the bean pressing frame having a bean dropping channel running from top to bottom, the bean discharging pipe being installed at the lower part of the bean pressing frame and connected to the bean dropping channel, the bean pressing plate being located on one side of the bean dropping channel, a return spring being provided between the side of the bean pressing plate facing the bean dropping channel and the bean pressing frame, the other side of the bean pressing plate contacting the cam and having a pressure plate hinge seat at the lower part of that side, the bean storage bin having a bean dropping pipe at the bottom, the bean dropping pipe being installed at the upper part of the bean pressing frame and connected to the bean dropping channel;

[0005] The lower part of the bean pressing frame is provided with an outer frame hinge seat. Both sides of the bean pressing frame are provided with sliding grooves. A slider is provided in the sliding groove. Compression springs are provided on both sides of the slider and the inner wall of the sliding groove. The cam is provided with a drive shaft. The two ends of the drive shaft are respectively mounted on the two sliders and connected to the bean pressing stepper motor. The bean pressing stepper motor drives the cam to rotate.

[0006] The rocker arm has an elongated hole in its middle. One end of the rocker arm is hinged to the pressure plate hinge seat via a first pin, and the middle part of the rocker arm is hinged to the outer frame hinge seat via a second pin, which passes through the elongated hole. The other end of the rocker arm is hinged to one end of the connecting rod via a third pin, and the other end of the connecting rod is hinged to the clamping plate via a fourth pin. The clamping plate extends into the bean outlet tube. When the near-recess point of the cam contacts the pressure plate, the beans in the bean drop channel flow normally, and the clamping plate extends into the bean outlet tube to prevent the beans from flowing out. When the far-recess point of the cam contacts the pressure plate, the pressure plate moves towards the bean drop channel, squeezing the beans into the channel. Through the linkage of the rocker arm and the connecting rod, the clamping plate is pulled out of the bean outlet tube, and the beans located below the drop channel flow out of the bean outlet tube.

[0007] A more specific technical solution than the above-mentioned technical solution is that: a rubber sheet is provided on the side of the bean pressing plate facing the bean dropping channel, and the rubber sheet is adhered to the surface of the bean pressing plate to prevent damage to the bean seeds.

[0008] Furthermore: The lower part of the bean storage bin is provided with a bean-distributing roller. One end of the bean-distributing roller is connected to a bean-distributing stepper motor, and the other end of the bean-distributing roller is provided with multiple levers. One of the levers extends into the interior of the bean storage bin. The bean-distributing stepper motor drives the bean-distributing roller to rotate, causing the lever to distribute the beans inside the bean storage bin, preventing beans from getting stuck, and allowing the beans to flow smoothly into the bean drop tube.

[0009] Furthermore, an opening groove is provided on one side of the bean outlet tube, and the clamping plate extends into the bean outlet tube from the opening groove.

[0010] Furthermore, the bean pressing frame and the bean outlet tube are connected by threads.

[0011] Due to the adoption of the above technical solution, this utility model has the following beneficial effects compared with the prior art: the cam rotation causes the pressing plate to move horizontally to press and remove the beans from the bean dropping channel. Then, through the linkage of the rocker arm and connecting rod with the pressing plate, the clamping plate extends into and out of the bean outlet pipe as the pressing plate moves horizontally, so that the beans fall periodically onto the cultivated land. The rotation period of the cam can be adjusted according to the needs of the pressing stepper motor to achieve the purpose of fixed-distance sowing, and the beans will not be damaged due to different sizes.
