Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a bean seed screening and sowing device, specifically an automated bean screening and planting device for an assembly line. Background Technology

[0002] With the rapid development of agricultural technology, more and more automation technologies are being integrated into agriculture, effectively improving efficiency and greatly reducing labor intensity. However, the cultivation of legumes still faces the following problems, resulting in a low level of automated sowing:

[0003] 1. Traditional bean cultivation requires manual screening and sowing, which is inefficient and prone to the introduction of bad beans / impurities.

[0004] 2. Currently, most bean sieving machines and seeders are independent devices, and the connection process can lead to damage to the beans or secondary contamination.

[0005] 3. Insufficient sowing precision makes it difficult to adapt to different soil conditions and planting density requirements.

[0006] To address the aforementioned issues, there is a need for an automated bean screening and sowing device that integrates screening and sowing functions on a production line. Through multi-stage screening and intelligent sowing technology, manual intervention can be reduced, thereby improving sowing quality and efficiency. Utility Model Content

[0007] This invention aims to solve the problems existing in the prior art by providing an automated bean planting device for a production line, which addresses the issues of low efficiency and poor precision in bean planting and meets the demand for improving planting quality and efficiency.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: This automated bean planting device for production lines includes a frame and a PLC control circuit located on it. The frame is equipped with a conveyor belt for transporting seed trays, a hopper for adding bean seeds and placing them one by one, and symmetrically arranged sorting worms connected to the PLC control circuit, which are horizontally positioned directly below the outlet of the hopper. The frame is also equipped with a leveling plate located between the conveyor belt and the outlet of the sorting worm. The leveling plate is composed of an upper fence assembly that surrounds the bean seeds and a lower substrate that can be adapted to different sizes of seed trays. The lower substrate has through holes evenly distributed vertically, and a vibration module is fixed on the lower substrate. A movable baffle that blocks the through holes is attached to the bottom of the lower substrate. The upper fence assembly and the lower substrate, together with the vibration module, form a uniform sowing structure where the bean seeds are evenly placed into the seed trays of the corresponding sizes after the movable baffle releases the blockage of the through holes. With this setup, when the device operates in bean sieving mode, the PLC control circuit runs the control program, and then the beans to be screened are added to the hopper. The beans fall one by one from the bottom outlet of the hopper onto the sorting worm. The distance between the sorting worms can be adjusted according to the size of the beans. As the sorting worm rotates, beans that do not meet the size requirements are automatically removed. When the sorting worm rotates forward, normal beans fall one by one into the lower equalizing plate as the worm rotates forward. During this process, beans that do not meet the size requirements will fall outside the equalizing plate as the worm moves forward. After the soybean seeds fall from the sorting worm, they first land in the area enclosed by the upper enclosure component of the equalizing plate. This area corresponds to the size of the prepared seedling trays, meaning the upper enclosure component can be adjusted according to the tray size via a PLC control circuit. Then, the seeds on the lower substrate begin to vibrate under the influence of the vibration module until they are evenly distributed within the through-holes of the lower substrate. Vibration then stops, and the device starts the sowing mode. At this point, the seedling trays are transported to the lower substrate by a conveyor belt. A movable baffle then moves to release the blockage of the through-holes in the lower substrate, and the seeds fall into the various seedling trays, ending the entire process. This process repeats until new seedling trays arrive, completing steps one through three to finish the entire process from sorting and seed preparation to sowing.

[0009] As a further improvement of this utility model, the upper fence component includes a fixed block and three movable blocks. The movable blocks and the fixed block are slidably connected by a slide rail. The slide rail, the movable blocks, and the fixed block together form a rectangular structure of the upper fence component that adapts to the size of the pit. With this configuration, the three movable blocks and the fixed block form a rectangular structure of the upper fence component that adapts to the size of the pit via the slide rail. The fixed block itself is fixed in position, and the movement of the two movable blocks adjacent to the fixed block causes the third movable block to automatically move adaptively along the slide rail, thereby achieving the effect of adjusting the size of the rectangle formed by the upper fence component.

[0010] As a further improvement of this utility model, sliders are connected to two adjacent movable blocks of the fixed block. The sliders are slidably connected to the frame along the slide rail. A motor connected to the PLC control circuit is fixed to the frame, and a lead screw is connected to the motor output. The lead screw is driven by the slider. In this process, the PLC control circuit first controls the motor to drive the lead screw according to the requirements of various seed types and the size of the seed tray. Then, the slider moves with the rotation of the lead screw, thereby moving the two adjacent movable blocks of the fixed block connected to the slider. Finally, the area enclosed by the slide rail, movable blocks, and fixed block can be adjusted and changed according to the requirements.

[0011] As a further improvement of this utility model, a vision inspection module is provided on the frame behind the sorting worm. The vision inspection module is connected to the PLC control circuit and works with the sorting worm to reverse, forming a screening structure that moves large-sized beans or foreign objects backwards for discharge. The vision inspection module is used to observe whether large-sized beans or foreign objects fall onto the sorting worm. If so, the PLC control circuit controls the sorting worm to reverse and transport the large-sized beans or foreign objects to the outside, effectively preventing large-sized beans or foreign objects from being transferred to the uniform material plate through the forward transfer of the sorting worm, thus reducing the possibility of unsuitable beans and foreign objects entering the sowing stage from the source.

[0012] As a further improvement of this utility model, a discharge chute for receiving and transporting substandard soybean seeds is connected to the frame and located at the bottom of the sorting worm. The discharge chute has an inclined structure with a higher front and lower back. The discharge chute is used to receive substandard soybean seeds that fall off after being rejected by the sorting worm. Due to the inclined structure of the discharge chute, the substandard soybean seeds will naturally slide down the discharge chute into the external collection device, minimizing the labor required for subsequent collection of substandard soybean seeds and achieving efficient recycling of inferior soybean seeds.

[0013] As a further improvement of this utility model, the frame is equipped with a sensor that is close to the leveling plate and detects the uniformity of the seed distribution on the lower substrate. The sensor is connected to a PLC control circuit. The sensor is used to detect the uniformity of the seed distribution on the lower substrate, and the connection to the PLC control circuit provides conditions for subsequent sowing into the seed trays.

[0014] As a further improvement to this invention, the vertical heights of adjacent slide rails are staggered. This arrangement prevents interference between adjacent slide rails during movement, greatly ensuring their freedom of movement and reliability.

[0015] As a further improvement of this utility model, an electric roller connected to the bottom of the frame and linked to the PLC control circuit is provided. A control panel connected to the PLC control circuit is also provided on the frame. The electric roller can adapt to the planting length and size requirements of different planting scenarios, reducing manual pushing and improving movement efficiency; the control panel is used to operate various functions, facilitating user control.

[0016] The beneficial effects of this utility model are: the structure of this utility model is reasonable and compact. By adopting a modular design, it uses a sorting worm gear to screen the bean seeds, and then uses a uniform plate to evenly arrange the bean seeds before sowing them into the seed trays. The whole process is fully automated, efficiently screening out mixed bad beans / impurities. It integrates multiple independent devices of traditional bean screening machines and planters into one device, reducing bean damage or secondary pollution, greatly improving sowing accuracy, effectively adapting to different soil conditions and planting density requirements, and can be adapted to a variety of bean crop seeds, especially suitable for large-scale bean planting bases.
