Description

Technical Field

[0001] This utility model relates to the field of reseeding devices, specifically a grassland seed reseeding device. Background Technology

[0002] The main purpose of grassland seed reseeding is to restore and improve the ecological environment of degraded grasslands, and enhance grassland productivity and ecological service functions. Through reseeding, grassland vegetation coverage can be increased, the proportion of high-quality forage grasses can be increased, grass structure can be optimized, and the stability and sustainable development of grassland ecosystems can be promoted.

[0003] Grassland seed reseeding is generally carried out by a combination of a reseeding mechanism and a compaction mechanism. The reseeding mechanism usually includes a furrow opener, a diverting roller, and a seed drill, while the compaction mechanism presses the reseeded seeds into the soil.

[0004] When reseeding grassland seeds, the seeds and fertilizer are usually poured directly into the device. However, during use and observation, it was found that a large amount of material would accumulate inside the device, causing blockages and affecting the reseeding process.

[0005] Therefore, a grassland seed reseeding device is proposed to address the above problems. Utility Model Content

[0008] Preferably, the first cover plate has a first groove in the middle; a plurality of springs are fixedly connected to the inner wall of the first groove; a sealing plate is fixedly connected to the end of the spring; the sealing plate and the first groove are in sliding fit; the second cover plate has a second groove in the middle; the sealing plate and the second groove are in sliding fit; through the cooperation of the spring and the sealing plate, the sealing plate will fill the gap between the first cover plate and the second cover plate under the elastic force of the spring, thereby improving the sealing performance of the joint between the first cover plate and the second cover plate and enhancing the load-bearing capacity of the first cover plate and the second cover plate for materials.

[0009] Preferably, a plurality of elastic ropes are fixedly connected to the middle of the sealing plate; the elastic ropes and the second slide groove are fixedly connected; when the first cover plate and the second cover plate are separated, the lengths of the elastic ropes and springs will change, at which time the sealing plate will be subjected to the elastic force between the elastic ropes and springs, reducing the movement of the sealing plate caused by the spring force; when the first cover plate and the second cover plate are connected, the pulling force of the elastic ropes on the sealing plate makes the sealing plate easily enter the second slide groove, improving the convenience of the sealing plate re-entering the second slide groove.

[0010] Preferably, the inner wall of the second chute is fixedly connected with multiple limiting plates; the top of the limiting plate is provided with a limiting groove; the limiting groove and the elastic rope are correspondingly arranged; when the first cover plate and the second cover plate are separated or connected, the length of the elastic rope will change with the sealing plate, because the elastic rope and the limiting plate are in contact through the limiting groove, the limiting groove will limit the elastic rope, reduce the shaking that occurs when the elastic rope deforms, and at the same time the limiting plate will also block the sealing plate, so that the sealing plate can be at the bottom of the connection between the first cover plate and the second cover plate, improving the stability of the sealing plate for the gap.

[0011] Preferably, multiple guide plates are fixedly connected to the top of the first and second cover plates; the guide plates are inclined; adjacent guide plates and replanting components are correspondingly arranged; after the material reaches the top of the first and second cover plates, it will slide down along their surfaces when the first and second cover plates separate. Because the guide plates are inclined, the material will be guided by the guide plates when it moves, and the material will fall more accurately into the replanting component, thus realizing the device's guidance of the material flow path.

[0012] Preferably, a plurality of ball bearings are rotatably connected to the middle of the cam; the ball bearings are arranged in a circumferential array; when the cam presses against the first cover plate and the second cover plate, the ball bearings will also come into contact with the first cover plate and the second cover plate, and the ball bearings will rotate under the action of friction, thereby reducing the friction between the cam and the first cover plate and the second cover plate.

[0013] The advantages of this utility model are:

[0014] 1.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 and Figure 5 As shown in the figure, a grassland seed reseeding device according to an embodiment of the present invention includes a housing 1; multiple reseeding components 12 are installed at the bottom of the housing 1; multiple pressing components 13 are installed at the bottom of the housing 1; a motor 14 is fixedly connected to the middle of the housing 1; a rotating shaft 15 is fixedly connected to the output end of the motor 14; the rotating shaft 15 and the housing 1 are through-connected and rotatably connected; multiple cams 16 are fixedly connected to the middle of the rotating shaft 15; a first cover plate 17 is rotatably connected to the inner wall of the housing 1; the housing 1 and the first cover plate 17 are connected by a torsion spring; a second cover plate 18 is rotatably connected to the inner wall of the housing 1; the housing 1 and the second cover plate 18 are connected by a torsion spring; the first cover plate 17 and the second cover plate 18 are symmetrically arranged; the cams 16 are located at the top of the first cover plate 17 and the second cover plate 18; during operation, a mixture of seeds and fertilizer is poured into the interior of the housing 1, and the material reaches the top of the first cover plate 17 and the second cover plate 18, and then the device is activated. Motor 14 causes shaft 15 to rotate, which in turn drives cam 16 to rotate. When cam 16 rotates, it squeezes the first cover plate 17 and the second cover plate 18, causing them to rotate along the housing 1 under the squeezing action of cam 16. At this time, material flows out from the cavity between the first cover plate 17 and the second cover plate 18 and enters the reseeding component 12. The reseeding component 12 sows the material. Then, the first cover plate 17 and the second cover plate 18 will return to their original positions under the action of torsion springs until the next time cam 16 squeezes the first cover plate 17 and the second cover plate 18. Meanwhile, the compaction component 13 compacts the sown grassland. When cam 16 rotates, it causes the first cover plate 17 and the second cover plate 18 to continuously connect and separate, allowing material to intermittently enter the reseeding component 12. This enables the device to control the amount of material fed in, reducing the amount of material accumulated at the bottom of the housing 1 and reducing the blockage of the reseeding component 12 caused by material accumulation.

[0026] Please see Figure 4 and Figure 5As shown, a first groove 2 is formed in the middle of the first cover plate 17; a plurality of springs 22 are fixedly connected to the inner wall of the first groove 2; a sealing plate 23 is fixedly connected to the end of the spring 22; the sealing plate 23 and the first groove 2 are in sliding fit; a second groove 24 is formed in the middle of the second cover plate 18; the sealing plate 23 and the second groove 24 are in sliding fit; when the first cover plate 17 and the second cover plate 18 carry materials, the sealing plate 23 will enter the interior of the second groove 24 under the elastic force of the spring 22, at which time the sealing plate 23 will be located between the first cover plate 17 and the second cover plate 18. Between the gaps of the first cover plate 17 and the second cover plate 18; the sealing plate 23 will seal the gaps. When the first cover plate 17 and the second cover plate 18 are separated under the squeezing action of the cam 16, the sealing plate 23 will disengage from the second slide groove 24 until the first cover plate 17 and the second cover plate 18 are connected again. Through the cooperation of the spring 22 and the sealing plate 23, the sealing plate 23 will fill the gap between the first cover plate 17 and the second cover plate 18 under the elastic force of the spring 22, improve the sealing performance of the connection between the first cover plate 17 and the second cover plate 18, and enhance the load-bearing capacity of the first cover plate 17 and the second cover plate 18 for materials.

[0027] Please see Figure 4 and Figure 5 As shown, multiple elastic ropes 3 are fixedly connected to the middle of the sealing plate 23; the elastic ropes 3 and the second slide groove 24 are fixedly connected; when the first cover plate 17 and the second cover plate 18 are separated, the lengths of the elastic ropes 3 and the springs 22 will change. At this time, the sealing plate 23 will be subjected to the elastic force between the elastic ropes 3 and the springs 22, reducing the movement of the sealing plate 23 caused by the elastic force of the springs 22. When the first cover plate 17 and the second cover plate 18 are connected, the pulling force of the elastic ropes 3 on the sealing plate 23 makes the sealing plate 23 easily enter the second slide groove 24, improving the convenience of the sealing plate 23 re-entering the second slide groove 24.

[0028] Please see Figure 5 As shown, multiple limiting plates 4 are fixed to the inner wall of the second slide 24; a limiting groove 42 is opened on the top of the limiting plate 4; the limiting groove 42 and the elastic rope 3 are correspondingly arranged; when the first cover plate 17 and the second cover plate 18 are separated or connected, the length of the elastic rope 3 will change with the sealing plate 23, because the elastic rope 3 and the limiting plate 4 are in contact through the limiting groove 42, the limiting groove 42 will limit the elastic rope 3, reduce the shaking that occurs when the elastic rope 3 is deformed, and at the same time the limiting plate 4 will also block the sealing plate 23, so that the sealing plate 23 can be at the bottom of the connection between the first cover plate 17 and the second cover plate 18, improving the stability of the sealing plate 23 for sealing the gap.

[0029] Please see Figure 4As shown, multiple guide plates 5 are fixedly connected to the top of the first cover plate 17 and the second cover plate 18; the guide plates 5 are inclined; adjacent guide plates 5 and the replanting component 12 are correspondingly arranged; after the material reaches the top of the first cover plate 17 and the second cover plate 18, it will slide down along its surface when the first cover plate 17 and the second cover plate 18 separate. Because the guide plates 5 are inclined, the material will be guided by the guide plates 5 when it moves, and the material will fall more accurately into the replanting component 12, realizing the device's guidance of the material flow path.

[0030] Please see Figure 3 As shown, a plurality of balls 6 are rotatably connected to the middle of the cam 16; the balls 6 are arranged in a circumferential array; when the cam 16 presses the first cover plate 17 and the second cover plate 18, the balls 6 will also come into contact with the first cover plate 17 and the second cover plate 18, and the balls 6 will rotate under friction, reducing the friction between the cam 16 and the first cover plate 17 and the second cover plate 18.

[0031] Please see Figure 1 and Figure 2 As shown, a baffle 7 is hinged to the top of the housing 1; the baffle 7 is located at the top of the rotating shaft 15; before operation, the baffle 7 can be opened and materials can be added to the inside of the housing 1. After the materials are added, the baffle 7 can be closed to keep the housing 1 in a sealed state, reducing the contamination of the materials inside the housing 1 by the outside.

[0032] Working principle: The mixture of seeds and fertilizer is poured into the interior of the housing 1. The material reaches the top of the first cover plate 17 and the second cover plate 18. Then, the motor 14 is started, causing the rotating shaft 15 to rotate. The rotating shaft 15 drives the cam 16 to rotate as well. When the cam 16 rotates, it squeezes the first cover plate 17 and the second cover plate 18, causing them to rotate along the housing 1 under the squeezing action of the cam 16. At this time, the material flows out from the cavity between the first cover plate 17 and the second cover plate 18 and enters the reseeding component 12. The reseeding component 12 sows the material. Afterward, the first cover plate 17 and the second cover plate 18 will return to their original position under the action of the torsion spring until the next convex... Wheel 16 presses against the first cover plate 17 and the second cover plate 18, while the compaction assembly 13 compacts the sown grassland soil. When the first cover plate 17 and the second cover plate 18 bear the material, the sealing plate 23 enters the interior of the second slide groove 24 under the elastic force of the spring 22. At this time, the sealing plate 23 is located between the gap between the first cover plate 17 and the second cover plate 18. The sealing plate 23 seals the gap. When the first cover plate 17 and the second cover plate 18 separate under the pressing action of the cam 16, the sealing plate 23 will disengage from the second slide groove 24 until the first cover plate 17 and the second cover plate 18 are connected again. When the first cover plate 17 and the second cover plate 18 separate, the elastic rope... The lengths of the elastic rope 3 and spring 22 will change. At this time, the sealing plate 23 will be subjected to the elastic force between the elastic rope 3 and spring 22, reducing the movement of the sealing plate 23 due to the elastic force of spring 22. When the first cover plate 17 and the second cover plate 18 are connected, the tension of the elastic rope 3 on the sealing plate 23 will allow the sealing plate 23 to easily enter the second slide groove 24. When the first cover plate 17 and the second cover plate 18 are separated or connected, the length of the elastic rope 3 will change with the sealing plate 23. This is because the elastic rope 3 and the limiting plate 4 are in contact through the limiting groove 42. The limiting groove 42 will limit the elastic rope 3, reducing the shaking that occurs when the elastic rope 3 deforms. At the same time, the limiting plate 4 will also limit the sealing plate 23. The blocking effect allows the sealing plate 23 to be positioned at the bottom of the joint between the first cover plate 17 and the second cover plate 18. After the material reaches the top of the first cover plate 17 and the second cover plate 18, it will slide down along their surfaces when the first cover plate 17 and the second cover plate 18 separate. Because the guide plate 5 is inclined, the material will be guided by the guide plate 5 when it moves. When the cam 16 presses the first cover plate 17 and the second cover plate 18, the ball bearing 6 will also come into contact with the first cover plate 17 and the second cover plate 18, and the ball bearing 6 will rotate under friction. Before operation, the baffle 7 can be opened to replenish the material inside the housing 1. After replenishment, the baffle 7 can be closed to seal the housing 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
