Description

Technical Field

[0001] This invention belongs to the field of crop breeding technology, and specifically relates to a wheat breeding device and its usage method. Background Technology

[0002] Wheat breeding is an important means of cultivating superior wheat varieties, including natural mutation breeding, artificial mutation breeding, hybridization breeding, and other methods. Wheat breeding equipment is a specialized technical equipment applied to the entire process of wheat genetic improvement and variety selection. Its core function is to improve breeding efficiency and variety quality by precisely controlling environmental conditions, automating the collection of phenotypic data, and optimizing key links such as sowing and pollination.

[0003] Current wheat breeding equipment exhibits two key deficiencies in actual operation: First, the seed pretreatment function is lacking, and most equipment is not equipped with efficient screening devices, making it difficult to thoroughly remove impurities such as soil and husks adhering to the surface of wheat seeds, which can easily lead to blockage of the seed delivery tube or affect the germination rate during sowing; Second, the sowing uniformity is insufficient, resulting in uneven distribution of the population in the field, which wastes germplasm resources and increases the cost of later management. Summary of the Invention

[0004] In view of the problems in the related technologies, the present invention proposes a wheat breeding device and its usage method to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a wheat breeding device, comprising a frame with a feed inlet on top of the frame, the feed inlet being connected to a processing box. Inside the processing box, a sowing wheel and a rotating wheel are rotatably mounted. A soft brush is fixedly mounted on the surface of the rotating wheel, and a seed-receiving groove is formed on the surface of the sowing wheel. A transmission mechanism is provided on the outer surface of the processing box, the transmission mechanism being used to control the sowing wheel and the rotating wheel to rotate synchronously in opposite directions. A cam is fixedly mounted on the sowing wheel, and a connecting rod is rotatably mounted on the protruding end of the cam. The other end of the connecting rod is rotatably mounted on a feeding pipe, which is connected to the bottom of the processing box, and a seed nozzle is fixedly mounted on the feeding pipe.

[0006] Furthermore, the processing box is fixedly installed with a connector, which is fixedly installed on a fixed plate by bolts. One end of a support rod is fixedly installed on the bottom of the fixed plate, and the other end of the support rod is fixedly installed on the vehicle frame.

[0007] Furthermore, the soft brush and the seed receiving groove are provided in several units and are evenly distributed around the circumference. The transmission mechanism includes a first gear fixedly mounted on the sowing wheel, the first gear being rotatably mounted on the processing box, the first gear meshing with a second gear, the second gear being rotatably mounted on the processing box, and the second gear being fixedly mounted on the rotating wheel.

[0008] Furthermore, the second gear meshes with a third gear, the third gear is fixedly mounted on the output end of the drive motor, the drive motor is fixedly mounted on a fixed plate, the cam is rotatably mounted on the other side of the processing box, the feeding pipe is slidably connected to the bottom of the processing box, and the seed nozzle is connected to the feeding pipe and is inclined downward.

[0009] Furthermore, one end of the frame is fixedly mounted with a rod, and there are two rods. A plowing roller is rotatably mounted between the other ends of the two rods, and the surface of the plowing roller is provided with spiral protrusions.

[0010] Furthermore, the frame is rotatably mounted with four rollers, which are distributed symmetrically around the frame.

[0011] Furthermore, the front end of the vehicle frame is provided with a soil-opening mechanism, which includes a first connecting shaft and soil-opening wheels. The first connecting shaft is rotatably installed inside the vehicle frame, and the soil-opening wheels are fixedly installed on the first connecting shaft. There are two soil-opening wheels, and the two soil-opening wheels have a conical structure that is narrower at the top and wider at the bottom.

[0012] Furthermore, a soil-burying mechanism is provided at the rear end of the vehicle frame. The soil-burying mechanism includes a second connecting shaft and soil-burying wheels. The second connecting shaft is rotatably installed inside the vehicle frame, and the soil-burying wheels are fixedly installed on the second connecting shaft. There are two soil-burying wheels, and the two soil-burying wheels have an inverted conical structure that is wider at the top and narrower at the bottom. A control component is provided on the top of the vehicle frame. The control component is used to control the drive motor, the soil-opening wheel, the roller, and the soil-burying wheel to work.

[0013] The present invention has the following beneficial effects: 1. This wheat breeding equipment achieves precise sowing and seed pretreatment through a unique structural design. After the seeds are introduced into the treatment box through the feed inlet, the rotating wheel drives the soft brush on the surface to rotate, effectively cleaning impurities from the seed surface and ensuring seed purity, laying the foundation for healthy growth. Simultaneously, the seed receiving trough on the sowing wheel can quantitatively hold seeds. In conjunction with a cam that drives the connecting rod, the feeding pipe slides up and down. When the seed receiving trough rotates to the position opposite to the feeding pipe, the seeds accurately fall in and are sown into the soil through the seed nozzle. This precise sowing method ensures even seed distribution, avoiding over-density or under-density sowing, which is beneficial for improving the survival rate and yield of wheat.

[0014] 2. This equipment integrates multiple functions such as soil clearing, sowing, plowing, movement, and soil covering. The soil clearing mechanism uses soil-clearing wheels to cultivate the soil, creating suitable conditions for sowing; the plowing rollers turn the soil over as the equipment moves, optimizing the soil structure; the rollers drive the entire equipment to move, enabling continuous operation; the soil covering mechanism uses soil-covering wheels to cover the soil after seed sowing, completing the entire breeding process. Operators can start the equipment through control components, enabling all parts to work together without switching between different equipment and processes, greatly improving breeding efficiency and saving labor and time costs.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0021] Please see Figures 1-6 As shown, the present invention is a wheat breeding device, including a frame 1, with a feed inlet 2 on the top of the frame 1, which is connected to a processing box 3. A sowing wheel 4 and a rotating wheel 5 are rotatably mounted inside the processing box 3. A soft brush 6 is fixedly mounted on the surface of the rotating wheel 5. A seed receiving groove 7 is opened on the surface of the sowing wheel 4. A transmission mechanism is provided on the outer surface of the processing box 3. The transmission mechanism is used to precisely control the synchronous rotation of the sowing wheel 4 and the rotating wheel 5. A cam 26 is fixedly mounted on the sowing wheel 4. One end of a connecting rod 8 is rotatably mounted on the protruding end of the cam 26. The other end of the connecting rod 8 is rotatably mounted on a feeding pipe 9. The feeding pipe 9 is connected to the bottom of the processing box 2. A seed nozzle 10 is fixedly mounted on the feeding pipe 9.

[0022] The working principle of the wheat breeding equipment proposed in this invention is as follows: during operation, wheat seeds are poured in from the feed inlet 2 above the frame 1, and the seeds enter the processing box 3, which is connected to the feed inlet 2.

[0023] The external transmission mechanism of the treatment box 3 starts to operate, precisely controlling the synchronous rotation of the internally mounted seeding wheel 4 and rotating wheel 5. During the rotation of the rotating wheel 5, the soft brush 6 fixedly mounted on its surface cleans the seeds entering the treatment box 3, removing any impurities that may be attached to the seed surface.

[0024] Meanwhile, the seeding wheel 4 continues to rotate, and the seed-containing groove 7 on its surface will hold a certain number of seeds when it rotates to a suitable position. As the seeding wheel 4 continues to rotate, when the seed-containing groove 7 rotates to a specific position, the seeds will prepare to fall due to gravity and other factors.

[0025] As the seeding wheel 4 rotates, the cam 26, which is fixedly mounted on the seeding wheel 4, also rotates. One end of the connecting rod 8 is rotatably mounted on the protruding end of the cam 26. As the cam 26 rotates, the position of its protruding end changes continuously, thereby driving the connecting rod 8 to reciprocate. The other end of the connecting rod 8 is rotatably mounted on the feed pipe 9, and the reciprocating motion of the connecting rod 8 causes the feed pipe 9 to slide up and down.

[0026] When the seed holding trough 7 rotates to a position opposite to the feeding pipe 9, the seeds fall from the seed holding trough 7 into the feeding pipe 9, which is connected to the bottom of the processing box 3, and are then sown into the soil through the seed nozzle 10 fixedly installed at the bottom of the feeding pipe 9, thus completing the sowing work for wheat breeding.

[0027] In one embodiment, for the above-mentioned processing box 3, the processing box 3 is fixedly installed with a connector 11, the connector 11 is fixedly installed on the fixing plate 13 by high-strength bolts 12, one end of the support rod 14 is vertically fixedly installed at the bottom of the fixing plate 13, and the other end of the support rod 14 is firmly fixedly installed on the frame 1.

[0028] In one embodiment, for the soft brush 6, both the soft brush 6 and the seed receiving groove 7 are provided in a plurality of them and are evenly distributed in a circle. The transmission mechanism includes a first gear 15 fixedly installed on the sowing wheel 4. The first gear 15 is rotatably installed on the processing box 3 through a bearing. The first gear 15 is precisely meshed with a second gear 16. The second gear 16 is rotatably installed on the processing box 3 through a bearing. The second gear 16 is firmly fixedly installed on the rotating wheel 5.

[0029] In one embodiment, the second gear 16 meshes with a third gear 17. The third gear 17 is fixedly mounted on the output end of the drive motor 18 by a key connection. The drive motor 18 is fixedly mounted on the fixed plate 13 by bolts. The cam 26 is rotatably mounted on the other side of the processing box 3 by a bearing. The feed pipe 9 is slidably connected to the bottom of the processing box 3 by a slide rail. The seed nozzle 10 and the feed pipe 9 are in communication with each other.

[0030] The working principle of the wheat breeding equipment proposed in this invention is as follows: during operation, wheat seeds are first poured into the feed inlet 2 above the frame 1, and the seeds enter the processing box 3 connected to it through the feed inlet 2.

[0031] The processing box 3 is securely mounted on the fixing plate 13 by means of the fixed installation connector 11 and high-strength bolts 12. The other end of the support rod 14, which is vertically fixed at the bottom of the fixing plate 13, is firmly connected to the frame 1, providing stable support for the entire processing box 3.

[0032] The drive motor 18, bolted to the fixed plate 13, is activated. The output of the drive motor 18, connected via a key, drives the third gear 17 to rotate. The third gear 17 precisely meshes with the second gear 16, thus driving the second gear 16 to rotate. The second gear 16 is rotatably mounted on the processing box 3 via bearings and firmly fixed to the rotating wheel 5, causing the rotating wheel 5 to rotate accordingly. Several soft brushes 6 are evenly distributed circumferentially on the surface of the rotating wheel 5, cleaning the seeds entering the processing box 3.

[0033] Simultaneously, the second gear 16 precisely meshes with the first gear 15, which is rotatably mounted on the processing box 3 via a bearing. The first gear 15 is fixedly mounted on the seeding wheel 4, thereby driving the seeding wheel 4 to rotate. Several seed-accepting grooves 7 are evenly distributed circumferentially on the surface of the seeding wheel 4. As the seeding wheel 4 rotates, the seed-accepting grooves 7 sequentially collect seeds.

[0034] During the rotation of the seeding wheel 4, the cam 26, which is fixedly mounted on the seeding wheel 4, rotates on the other side of the treatment box 3 via a bearing. The protruding end of the cam 26 is rotatably connected to one end of the connecting rod 8, and the other end of the connecting rod 8 is rotatably connected to the discharge pipe 9, which is slidably connected to the bottom of the treatment box 3 via a slide rail. When the cam 26 rotates, the position of its protruding end changes, causing the connecting rod 8 to reciprocate, thereby causing the discharge pipe 9 to slide up and down.

[0035] When the seed container 7 containing the seeds rotates to a position opposite to the feeding pipe 9, the seeds fall into the feeding pipe 9 and are then sown into the soil through the seed nozzle 10, which is connected to the feeding pipe 9, thus completing the wheat breeding and sowing work.

[0036] In one embodiment, for the frame 1 described above, one end of the frame 1 is welded and fixedly installed with a rod 19. There are two rods 19 arranged symmetrically, and a plowing roller 20 is rotatably installed between the other ends of the two rods 19 via a bearing.

[0037] In one embodiment, for the aforementioned frame 1, the frame 1 is rotatably mounted with rollers 21 via bearings. There are four rollers 21, which are evenly distributed around the frame 1 and arranged in a rectangular pattern.

[0038] In one embodiment, for the aforementioned frame 1, a soil-opening mechanism is provided at the front end of the frame 1. The soil-opening mechanism includes a first connecting shaft 22 and a soil-opening wheel 23. The first connecting shaft 22 is rotatably mounted inside the frame 1 via a bearing. The soil-opening wheel 23 is fixedly mounted on the first connecting shaft 22 via a key connection. There are two soil-opening wheels 23, which are symmetrically distributed. The two soil-opening wheels 23 present a trapezoidal shape that is narrower at the top and wider at the bottom.

[0039] In one embodiment, for the aforementioned vehicle frame 1, a soil-burying mechanism is provided at the rear end of the vehicle frame 1. The soil-burying mechanism includes a second connecting shaft 24 and soil-burying wheels 25. The second connecting shaft 24 is rotatably mounted inside the vehicle frame 1 via bearings. The soil-burying wheels 25 are fixedly mounted on the second connecting shaft 24 via key connections. There are two soil-burying wheels 25, which are symmetrically distributed. The two soil-burying wheels 25 are trapezoidal in shape, wider at the top and narrower at the bottom. A control component 27 is provided above the vehicle frame 1. The control component 27 is used to control the drive motor 18, the soil-opening wheel 23, the roller 21, and the soil-burying wheel 25 to work.

[0040] The working principle of the wheat breeding equipment proposed in this invention is as follows: when working, the operator starts the equipment through the control component 27 set above the frame 1. The control component 27 issues a command to make the drive motor 18, the soil-opening wheel 23, the roller 21 and the soil-burying wheel 25 start working.

[0041] The soil-opening mechanism at the front end of the frame 1 is activated first. The first connecting shaft 22 is rotatably mounted inside the frame 1 via a bearing. Two symmetrically distributed soil-opening wheels 23, which are trapezoidal in shape with a narrow top and a wide bottom, are fixedly mounted on the first connecting shaft 22 via a key connection. As the first connecting shaft 22 rotates, the soil-opening wheels 23 rotate, opening up the soil in front and creating suitable soil conditions for subsequent sowing.

[0042] Meanwhile, wheat seeds are poured into the feed inlet 2 above the frame 1, and the seeds enter the processing box 3 connected to it through the feed inlet 2. The processing box 3 is securely mounted on the fixing plate 13 by means of the fixed connector 11 and high-strength bolts 12. The other end of the support rod 14 vertically fixed at the bottom of the fixing plate 13 is firmly connected to the frame 1, providing stable support for the processing box 3.

[0043] The drive motor 18 is bolted to the fixed plate 13, and its output end is connected to the key to drive the third gear 17 to rotate. The third gear 17 meshes precisely with the second gear 16, driving the second gear 16 to rotate. The second gear 16 is rotatably mounted on the processing box 3 through bearings and is firmly fixed on the rotating wheel 5. The rotating wheel 5 rotates accordingly, and several soft brushes 6 evenly distributed on its surface clean the seeds entering the processing box 3.

[0044] Simultaneously, the second gear 16 precisely meshes with the first gear 15, which is rotatably mounted on the processing box 3 via a bearing. The first gear 15 is fixedly mounted on the seeding wheel 4, driving the seeding wheel 4 to rotate. Several seed-accepting grooves 7, evenly distributed circumferentially on the surface of the seeding wheel 4, sequentially collect seeds.

[0045] During the rotation of the seeding wheel 4, the cam 26, fixedly mounted on the seeding wheel 4, rotates on the other side of the treatment box 3 via a bearing. The protruding end of the cam 26 is rotatably connected to one end of the connecting rod 8, and the other end of the connecting rod 8 is rotatably connected to the discharge pipe 9, which is slidably connected to the bottom of the treatment box 3 via a slide rail. When the cam 26 rotates, the position of its protruding end changes, causing the connecting rod 8 to reciprocate, thereby causing the discharge pipe 9 to slide up and down. When the seed receiving trough 7 containing seeds rotates to a position opposite to the discharge pipe 9, the seeds fall into the discharge pipe 9 and are then sown into the cultivated soil through the seed nozzle 10, which is connected to the discharge pipe 9.

[0046] During the movement of the equipment, two symmetrically distributed rods 19 are welded and fixedly installed on the frame 1. A plowing roller 20 is rotatably mounted between the other ends of the two rods 19 via a bearing. The plowing roller 20 turns over the soil as the equipment moves. Four rollers 21, evenly distributed around the frame 1 in a rectangular arrangement, are rotatably mounted on the frame 1 via bearings. The rotation of the rollers 21 drives the entire equipment forward.

[0047] After the seeds are sown, the soil-burying mechanism at the rear of the frame 1 begins to operate. The second connecting shaft 24 is rotatably mounted inside the frame 1 via bearings. Two symmetrically distributed soil-burying wheels 25, which are trapezoidal in shape with a wider top and a narrower bottom, are fixedly mounted on the second connecting shaft 24 via a key connection. As the second connecting shaft 24 rotates, the soil-burying wheels 25 rotate, covering the soil after the seeds have been sown back onto the wheat, thus completing the wheat breeding, sowing, and subsequent treatment work.
