Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a medicinal seed film covering device. Background Art

[0002] Agricultural machinery film covering machines are often used in the process of planting medicinal seeds. The film covering machines can lay film on the ridge surface to maintain the temperature and humidity of the soil, prevent the soil from being directly affected by natural factors such as rain erosion and wind erosion, and help maintain the looseness and agglomeration structure of the soil, which is conducive to the growth of medicinal seeds.

[0003] The existing film covering machine is also equipped with a seeding wheel and a fertilizer spraying mechanism, and is equipped with an intelligent monitoring system and control system, which can automatically complete the transportation and deployment of the ground film, accurately control the laying of the ground film, and monitor the operating status of the equipment in real time. When working, the machine body moves along the top of the ridge surface, and the fertilizer spraying mechanism first sprays the fertilizer liquid on the ridge surface, and then covers the ridge surface with film, and then multiple seeding wheels puncture the film surface one by one and at equal intervals and insert the medicinal material seeds into the ridge surface. Finally, the edges of the two sides of the film will be buried by the film pressing wheel and the covering disc of the machine body and bound on both sides of the ridge.

[0004] However, if the fertilizer liquid is sprayed on the ridge surface first, the ridge surface will become wet. Since the duckbill sowing port of the sowing wheel will be continuously inserted into the ridge and then leave, this will cause the duckbill sowing port to easily adhere to a large amount of soil, and its opening and closing degree and the depth of insertion into the ridge surface will be easily affected, and even the sowing port will be blocked so that the medicinal seeds cannot be smoothly sown into the ridge surface through the sowing port, affecting the smooth sowing of the medicinal seeds. At the same time, the sowing method of the duckbill sowing port of the sowing wheel is: the closed state is inserted into the ridge to form a hole, and then it will immediately open to send the medicinal seeds into the ridge surface. The soil will be pushed away during the opening process. However, after the duckbill sowing port leaves the ridge, it will completely rely on the fall and collapse of the pushed away soil to bury the medicinal seeds, which is prone to incomplete burial, so that the medicinal seeds will be partially exposed to the outside world, which will have a negative impact on the growth of the medicinal seeds.

This is a well-known prior art and will not be elaborated on. When the sowing and covering support 2 moves, it will also drive the concave frame 5 and multiple material boxes 4 to move together. Each material box 4 corresponds to each sowing wheel 3, and each material box 4 is filled with crushed soil. Start the motor 2 13 above each material box 4 and the motor 1 8 installed outside the material tube 9 under each material box 4. The motor 2 13 can drive the stirring rod 15 to rotate, and the stirring rod 15 will continuously stir and disturb the crushed soil in the material box 4 to prevent the crushed soil from adhering to each other and becoming compacted.

Figure 5 and Figure 6 In the state shown, one of the troughs 20 will be filled with crushed soil. When the feeding barrel 21 rotates, the multiple troughs 20 on the feeding barrel 21 will rotate synchronously, and each trough 20 will be filled with soil in turn. When each trough 20 rotates to face directly downward, the crushed soil in each trough 20 will be discharged along the corresponding material pipe 9, and the discharge position each time corresponds to the hole left by the corresponding sowing wheel 3 in the ground film and the ridge surface, so as to fully bury the medicinal seeds and avoid partial exposure of the medicinal seeds to the outside, which will have a negative impact on the growth of the medicinal seeds.

[0025] Example 2: Please refer to Figure 5 - Figure 7 The present embodiment further explains the first embodiment, the discharge mechanism includes two groups of discharge pipes 28, two rubber plates 26 and two splicing plates 17, the two groups of discharge pipes 28 are respectively connected to the lower ends of the two boxes 24, the two rubber plates 26 are respectively attached to the inner bottom ends of the two boxes 24, and the two rubber plates 26 correspond to the two groups of discharge pipes 28, respectively, the two splicing plates 17 are respectively located above the two boxes 24, and the two splicing plates 17 are respectively close to the tops of the two boxes 24, a pressure component is respectively provided between the two rubber plates 26 and the two splicing plates 17, and a linkage component is provided between the two splicing plates 17 and the stirring rod 15.

[0026] The pressure-applying assembly includes two connecting frames 30, which are symmetrically fixedly connected to the upper end of the rubber plate 26, and the upper ends of the two connecting frames 30 are fixedly connected with connecting columns 23, and the two connecting columns 23 are movably passed through the top of the box body 24, and the top ends of the two connecting columns 23 are fixedly connected to the lower end of the splicing plate 17, and springs 31 are slidably sleeved on the outer walls of the two connecting columns 23, and the lower ends of the two springs 31 are respectively fixedly connected to the upper ends of the two connecting frames 30, and the upper ends of the two springs 31 are fixedly connected to the inner top of the box body 24.

[0027] The linkage assembly includes a T-shaped plate 16 and two L-shaped blocks 18. The T-shaped plate 16 is fixedly connected to the lower end of the stirring rod 15, and arc blocks 22 are fixedly connected to the edges of both sides of the upper end of the horizontal part of the T-shaped plate 16. The two L-shaped blocks 18 are respectively fixedly connected to the upper ends of the two splicing plates 17, and one side of the horizontal parts of the two L-shaped blocks 18 is inclined, and the horizontal parts of the two L-shaped blocks 18 are on the movement paths of the two arc blocks 22.

[0028] The upper edges of the walls of the two boxes 24 that are away from each other are connected with injection pipes 19, and the two injection pipes 19 are respectively movable and penetrate the front and rear end inner walls of the material pipe 9; specifically, the end of the injection pipe 19 away from the box 24 is sealed by a pipe cover, and the pipe cover is opened regularly and fertilizer liquid is injected into the injection pipe 19 to refill the box 24 with fertilizer liquid.

[0029] In this embodiment, the stirring rod 15 will also drive the T-shaped plate 16 and the two arc-shaped blocks 22 to rotate together during the rotation process. The two arc-shaped blocks 22 will pass through the inclined surface of one side of the horizontal part of the two L-shaped blocks 18 respectively, and the cycle will be repeated. During the process, the arc-shaped block 22 will squeeze the inclined surface of the L-shaped block 18. Under the action of the squeezing force, the L-shaped block 18 will be driven to move upward, and the L-shaped block 18 will drive the splicing plate 17 to move upward. The splicing plate 17 will drive the two connecting columns 23 to slide up in the corresponding box body 24, and the two connecting columns 23 will drive their respective connected The connecting frame 30 moves upward, and each connecting frame 30 squeezes the spring 1 31 connected to the box body 24, and the two connecting frames 30 drive the rubber plate 26 to move upward, then the fertilizer liquid contained in the box body 24 will be discharged along a row of drainage pipes 28, and when the arc block 22 rotates away from the L-shaped block 18, under the action of the spring 1 31, the L-shaped block 18, the splicing plate 17, the connecting column 23, the connecting frame 30 and the rubber plate 26 will reset and move downward, and the rubber plate 26 will be close to the bottom end of the box body 24, thereby continuing to block the row of drainage pipes 28.

[0030] To sum up, as the two arc blocks 22 continue to rotate, a row of drainage pipes 28 under the two boxes 24 will intermittently discharge fertilizer liquid, and when discharging the fertilizer liquid, a material trough 20 on the feeding barrel 21 will just turn to the bottom and discharge the crushed soil in the material trough 20, so that each time the crushed soil is discharged will be mixed with an appropriate amount of fertilizer liquid and buried on the medicinal seeds, which not only provides the nutrients required for the growth of the medicinal seeds, but also avoids the traditional large-scale spraying of fertilizer liquid on the ridge surface, which causes the ridge surface to be wet, resulting in a large amount of soil easily adhering to the sowing port of the sowing wheel 3, thereby ensuring the smooth sowing of the medicinal seeds.

[0031] Example 3: Please refer to Figure 7 - Fig.10 , this embodiment further explains the first embodiment, the soil vibrating mechanism includes a connecting rod 25 and three knocking plates 29, one end of the connecting rod 25 is fixedly connected to a side surface of the inside of the material tube 9 away from the motor 8, and the other end of the connecting rod 25 is movable through the feeding barrel 21, and the outer wall of the connecting rod 25 is symmetrically fixedly connected with an L-shaped block 27, and the horizontal parts of the two L-shaped blocks 27 are fixedly connected with a hemispherical block 38, one end of the three knocking plates 29 is attached to the inner wall of the feeding barrel 21 corresponding to the three material troughs 20 respectively, and elastic components are provided between the three knocking plates 29 and the inner wall of the feeding barrel 21, and the other ends of the three knocking plates 29 are symmetrically fixedly connected with an L-shaped block 2 34, and the horizontal parts of the six L-shaped blocks 2 34 are fixedly connected with a hemispherical block 2 33.

[0032] The elastic component includes two connecting blocks 32, and the two connecting blocks 32 are symmetrically fixedly connected to one side wall of the knocking plate 29, and the wall surfaces of the two connecting blocks 32 corresponding to the connecting rod 25 are fixedly connected with guide pillars 35, and the outer walls of the two guide pillars 35 are slidably sleeved with L-shaped blocks 37, and the ends of the two L-shaped blocks 37 away from the connecting rod 25 are fixedly connected to the inner wall of the feeding barrel 21, and springs 2 36 are fixedly connected between the two connecting blocks 32 and the two L-shaped blocks 37, respectively, and the two springs 2 36 are slidably sleeved on the outer walls of the two guide pillars 35.

[0033] In this embodiment, during the rotation of the feeding barrel 21, the three knocking plates 29 inside it will also be driven to rotate together. The two L-shaped blocks 234 under each knocking plate 29 and the hemispherical blocks 233 on the two L-shaped blocks 234 will rotate together and pass through the hemispherical blocks 138 on the two L-shaped blocks 137 respectively. The two L-shaped blocks 137 are fixedly connected to the connecting rod 25, and during the process, the two hemispherical blocks 233 will be squeezed with the two hemispherical blocks 138 respectively. Under the action of the squeezing force, the two L-shaped blocks 234 will move close to the connecting rod 25, thereby driving the knocking plate 29 close to the connecting rod 25. 5 moves, the knocking plate 29 will drive the two connecting blocks 32 to move close to the connecting rod 25, and the two connecting blocks 32 will also drive the guide pillars 35 connected to them to slide in the corresponding L-shaped blocks 3 37, and the two connecting blocks 32 will also squeeze the springs 2 36 connected between the two L-shaped blocks 3 37, when the two hemispherical blocks 2 33 will respectively turn away from the two hemispherical blocks 1 38, under the action of the springs 2 36, the L-shaped block 1 27, the hemispherical block 1 38, the knocking plate 29, the connecting blocks 32 and the guide pillars 35 will all be reset, and the knocking plate 29 will knock the inner wall of the feeding barrel 21 corresponding to the material groove 20.

[0034] To sum up, as the feeding barrel 21 continues to rotate, the three knocking plates 29 will intermittently knock on the inner wall of the feeding barrel 21, so that it is not easy for the crushed soil to gradually adhere to the three material troughs 20. Because the crushed soil has a certain viscosity, it is prevented that the crushed soil adheres to the material trough 20, resulting in a decrease in the capacity of the material trough 20 for the crushed soil, thereby ensuring that the amount of crushed soil falling on the medicinal seeds each time is uniform, ensuring that the medicinal seeds are completely buried by the crushed soil.

[0035] Example 4: Please refer to Figure 1 - Figure 3 The present embodiment further explains the first embodiment. The soil pressing mechanism includes a support frame 7 and a fixed plate 12. One end of the support frame 7 is rotatably connected to a side wall of the concave frame 5 away from the material box 4, and the other end of the support frame 7 is rotatably connected to the pressing wheel 6. The fixed plate 12 is fixedly connected to the lower end surface of the concave frame 5 corresponding to the support frame 7, and the fixed plate 12 is fixedly connected to the side wall of the support frame 7 corresponding to the support frame 7. The end of the arc rod 11 away from the fixed plate 12 movably passes through the support frame 7, and an arc spring 10 is slidably sleeved on the outer wall of the arc rod 11, and the arc spring 10 is fixedly connected between the support frame 7 and the fixed plate 12.

[0036] In this embodiment, when the mounting end of the sowing film covering support 2 is connected to the connecting end of the tractor and the tractor moves above the ridge surface with the sowing film covering support 2, multiple pressure wheels 6 will also roll on the ridge surface, and when the pressure wheel 6 is not originally on the ridge surface, its bottom is lower than the upper surface of the ridge. Then, when the pressure wheel 6 is driven to the ridge surface by the tractor and the sowing film covering support 2, the pressure wheel 6 will drive the support frame 7 to rotate upward, and the support frame 7 will rotate along the arc rod 11 and stretch the arc spring 10 connected to the fixed plate 12. Under the action of the arc spring 10, the pressure wheel 6 will apply a certain pressure to the ridge surface, and multiple pressure wheels 6 also correspond to multiple sowing wheels 3 respectively. Then, each time the medicinal seeds are sown and the crushed soil in the material box 4 is transported by the feeding barrel 21 to be buried at the medicinal seeds, the pressure wheel 6 will compact the buried crushed soil, which not only makes the medicinal seeds fully contact with the buried soil, but also makes the buried soil not easily blown away by the wind, further ensuring the smooth growth of the medicinal seeds.
