AI Technical Summary
Although existing hand-push seeders can maintain a constant speed of seed output, the uneven seeding intervals are caused by the inability of the operator to push the seeder at a constant speed, which affects plant growth.
A uniform sowing device is designed, comprising a base, a shell, rollers, a rotating shaft, a feeding mechanism, and a sowing mechanism. The rotating shaft is driven by the rollers to rotate, which in turn drives the circular plate and the turntable, so that the seeds are fed when the rollers travel an equal distance, ensuring that the seed sowing spacing is consistent. A motor-driven unblocking mechanism prevents seeds from bridging.
This achieves uniformity in seed sowing spacing, avoids seed bridging during the feeding process, and ensures uniformity and efficiency in seed sowing.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste gas treatment technology, specifically relating to a uniform seeding device for agricultural planting. Background Technology
[0002] Crop farming is a major component of agriculture. It is a social production sector that utilizes the life functions of plants to obtain food, by-products, feed, and industrial raw materials through artificial cultivation. It includes the cultivation of various crops, trees, fruit trees, medicinal plants, and ornamental plants. Types include food crops, cash crops, vegetable crops, green manure crops, forage crops, pasture grasses, and horticultural crops such as flowers. Small family farms often use a sowing method, employing small, hand-operated seeders instead of large seeding machines.
[0003] While existing push-type seeders can deliver seeds into the soil at a constant speed, the inability of operators to push the seeder at a uniform speed means that even with the same seeding interval, the seeding distance cannot be guaranteed to be the same, which can affect the subsequent growth of plants.

[0014] (3) Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] In this invention, when the roller rolls on the ground, causing the rotating shaft to rotate, the first belt shaft, the belt, and the second belt shaft drive the circular shaft to rotate, thereby causing the circular plate to rotate inside the circular frame. When the feeding trough at the edge of the circular plate rotates to the bottom of the connecting pipe, the seeds entering the connecting pipe from the bottom of the hopper will fall from the feeding port into the feeding trough. Then, the seeds will rotate together with the circular plate until they reach the bottom feeding port, at which point the seeds in the feeding trough will fall from the feeding port into the bottom receiving hopper. This ensures that the interval between seed feedings is related to the distance the roller rolls, and the distance the roller travels is the same during two seed feedings, thus guaranteeing that the seed sowing spacing is the same.
[0017] This invention utilizes a motor whose output shaft rotates to drive a rotating shaft and a lever inside the hopper, agitating the seeds inside the hopper. This prevents bridging of the seeds during the feeding process, thus ensuring proper feeding. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This specific embodiment is a uniform seeding device for agricultural planting, and its structural schematic diagram is shown below. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes a base 1, a housing 2 fixedly connected to the upper side of the base 1, a connecting block 3 fixedly connected to the lower side of the housing 2, a rotating shaft 4 rotatably connected inside the connecting block 3, rollers 5 fixedly connected to the front and rear ends of the rotating shaft 4, a feeding mechanism provided at the inner and outer ends of the housing 2, and a seeding mechanism provided inside the housing 2. The seeding mechanism includes a turntable 701 fixedly connected to the rear end of the outer side of the round shaft 602, a round rod 702 fixedly connected to the rear edge of the turntable 701, and two limiting rings 703 fixedly connected to the rear end of the round rod 702. A round hole is opened at the middle position of the upper end of the connecting rod 704, and the outer rear end of the round rod 702 is rotatably connected to the inner side of the round hole. The front and rear sides of the upper end of the connecting rod 704 are slidably connected to the side adjacent to the two limiting rings 703. A connecting rod 704 is connected to the rear end of the round rod 702, and a connecting piece 705 is hinged to the lower end of the connecting rod 704. A ramp 706 is fixedly connected to the lower end of the base 1, and a grounding tube 707 is fixedly connected to the lower end of the ramp 706. A receiving hopper 708 is fixedly connected to the front end of the grounding tube 707. A sliding hole is provided in the middle of the interior of the base 1. The outer side of the grounding tube 707 is slidably connected to the inner side of the sliding hole. The front end of the receiving hopper 708 is located below the circular frame 609. The circular rod 702 and the feeding groove at the edge of the circular plate 606 are at the same horizontal height. The circular shaft 602 rotates to drive the feed. As turntable 701 rotates, round rod 702 rotates together, causing the upper end of connecting rod 704 to rotate with turntable 701. This, in turn, causes the lower insertion tube 707 to move up and down along the inner side of the sliding hole. As the insertion tube 707 moves down, it inserts into the ground, causing the seeds falling into receiving hopper 708 to slide down the inner side of receiving hopper 708 into insertion tube 707. Finally, the seeds fall from the bottom of insertion tube 707 onto the ground, completing the planting of the seeds.
[0028] Cooperate Figure 5The feeding mechanism includes a bearing 601 installed at the front end of the housing 2, a round shaft 602 installed inside the bearing 601, a drive unit at the front end of the housing 2, the drive unit including a first belt shaft 603 fixedly connected to the outer front end of the right-side rotating shaft 4 below the base 1, a second belt shaft 604 fixedly connected to the outer front end of the round shaft 602, a belt 605 sleeved on the outer sides of the first belt shaft 603 and the second belt shaft 604, a round plate 606 fixedly connected at the middle position of the outer side of the round shaft 602, a feeding hopper 607 fixedly connected to the top of the housing 2, a connecting pipe 608 fixedly connected to the lower end of the feeding hopper 607, a round frame 609 fixedly connected to the lower end of the connecting pipe 608, a feeding port at the upper end of the round frame 609, a feeding port at the lower end of the round frame 609, a feeding groove at the edge of the round plate 606, and a rotating hole at the middle position of the front and rear ends of the round frame 609. The outer side of the roller 6 is rotatably connected to the inner side of the circular frame 609, and the outer side of the circular shaft 602 is rotatably connected to the inner side of the rotating hole. Thus, when the roller 5 rolls on the ground and causes the rotating shaft 4 to rotate, the circular shaft 602 can be rotated through the transmission of the first belt shaft 603, belt 605 and second belt shaft 604. This causes the circular plate 606 to rotate inside the circular frame 609. When the feed trough at the edge of the circular plate 606 rotates to the bottom of the connecting pipe 608, the seeds that enter the connecting pipe 608 from the bottom of the hopper 607 will fall from the feed inlet into the feed trough. Then, the circular plate 606 rotates together until it rotates to the bottom feed inlet. At this point, the seeds in the feed trough will fall from the feed inlet into the bottom receiving hopper 708. This ensures that the interval of seed feeding is related to the distance the roller 5 rolls. The distance the roller 5 travels is the same when feeding seeds twice, thus ensuring that the spacing between seed sowing is the same.
[0029] Cooperate Figure 6 The hopper 607 is equipped with a clearing mechanism, which includes a fixed plate 801 fixedly connected to the upper side of the hopper 607. A motor 802 is installed at the middle position of the upper side of the fixed plate 801. A rotating shaft 803 is fixedly connected to the lower end of the output shaft of the motor 802. A lever 804 is fixedly connected at equal intervals to the outer side of the rotating shaft 803. When the output shaft of the motor 802 is started, it can drive the rotating shaft 803 and the lever 804 to rotate inside the hopper 607, which agitates the seeds inside the hopper 607. This can prevent the seeds in the hopper 607 from bridging during the feeding process and thus prevent them from being fed normally.
[0030] Working principle: During sowing, the seeds to be sown are first poured into the feeding hopper 607. Then, the pushing device moves on the ground of the planting field. During the movement, the roller 5 rotates, driving the rotating shaft 4 to rotate as well. Through the transmission of the first belt shaft 603, the second belt shaft 604, and the belt 605, the circular shaft 602 rotates, which in turn drives the circular plate 606 and the turntable 701 to rotate together. When the circular plate 606 rotates, the feeding chute at its edge rotates to below the connecting pipe 608, and the seeds in the connecting pipe 608 are fed out from the feeding port. The seeds fall into the feeding trough, and then the circular plate 606 continues to rotate until it reaches the lower feeding port. When the rotation reaches the lower feeding port, the seeds in the feeding trough fall from the feeding port into the lower receiving hopper 708. As the receiving hopper 708 slides inside, it enters the planting tube 707. At this time, as the turntable 701 rotates, the bottom end of the planting tube 707 is inserted into the ground, so that the seeds entering the planting tube 707 fall from the bottom end of the planting tube 707 to the ground. As the device moves, this planting process is repeated to sow the seeds at equal intervals.
[0031] All technical features in this embodiment can be freely combined according to actual needs.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
