Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a batch-type green manure seed wiping machine. Background Technology

[0002] With the increasing national emphasis on fertilizer reduction and efficiency improvement strategies for arable land quality, the planting area of ​​green manure is rapidly increasing, with a dramatic surge in the use of milkvetch seeds, a typical and widely planted green manure in paddy fields. Milkvetch seeds require seed treatment before sowing, currently mainly achieved through manual sandpaper rubbing, which is time-consuming and labor-intensive. Sometimes, to save time and effort, seeds are soaked in water, salt water, or scalded before sowing, or even directly crushed with rollers. These methods easily lead to seed mold and reduced seed viability. Therefore, developing a lightweight and efficient seed-rubbing machine for milkvetch and other green manure seeds can alleviate the urgent need for green manure production.

[0003] In the prior art, patent CN215957044U discloses a seed-wiping device for milkvetch, which includes a rotating lifting cylinder and a seed-wiping collection cylinder inside the rotating lifting cylinder. The seed-wiping collection cylinder includes a seed-wiping plate, a collection port, and a collection plate. The seeds are wiped using the friction surface of the seed-wiping plate. This seed-wiping method requires the rotating lifting cylinder to rotate and continuously hit the milkvetch seeds onto the seed-wiping plate for wiping. The seed-wiping efficiency is determined by the area of ​​the friction surface and the rotation speed of the rotating lifting cylinder. In this solution, the installation method of the seed-wiping plate determines that the area of ​​its friction surface is limited, and the rotation speed of the rotating lifting cylinder should not be too fast, otherwise it will damage the seeds. Therefore, the efficiency that this solution can achieve is low. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a batch green manure seed wiping machine with simple structure, low cost, small size and high seed wiping efficiency.

[0005] Technical solution: To achieve the above objectives, the present invention provides a batch-type green manure seed wiping machine, which includes a frame on which a feeding component, a seed wiping component, a seed screening component, and a discharging component are installed;

[0006] The seed wiping component includes a cylindrical seed wiping cylinder and a seed wiping element placed inside the seed wiping cylinder, and the seed wiping cylinder is rotatable relative to the frame;

[0007] The seed screening component is a seed screening cylinder that is connected to and coaxially arranged with the seed wiping cylinder, and the outer surface of the seed screening cylinder has sieve holes; a screw conveyor is installed at the connection position between the seed wiping cylinder and the seed screening cylinder, and the maximum diameter of the screw conveyor is equal to the inner diameter of the seed wiping cylinder and the inner diameter of the seed screening cylinder; the seed wiping component can move inside the seed wiping cylinder and can enter the seed screening cylinder via the screw conveyor.

[0008] Furthermore, the seed-wiping component is a seed-wiping ball with an uneven surface. It can be a metal ball or a sand ball. When the seed-wiping ball is mixed with the green manure seeds and tumbles, it can gradually wipe away the wax layer on the surface of the green manure seeds to improve the water permeability of the green manure seeds and increase the germination rate after sowing.

[0009] During the seed-grinding operation, the seed-grinding ball is located inside the seed-screening cylinder. A batch of green manure seeds is fed into the seed-grinding cylinder by the feeding component. Then, the seed-grinding cylinder and the seed-screening cylinder rotate synchronously, and the screw conveyor rotates forward. At this time, the screw conveyor transports the material from the seed-screening cylinder into the seed-grinding cylinder. Since there is no material in the seed-screening cylinder, the screw conveyor does not transport material at this time, but it acts as a barrier to prevent material from entering the seed-screening cylinder. In this way, the green manure seeds and the seed-grinding ball can rub thoroughly inside the seed-grinding cylinder, gradually removing the wax layer on the surface of the green manure seeds. After the seed-grinding is completed, the screw conveyor rotates in the reverse direction. At this time, the mixture of seed-grinding balls and green manure seeds in the seed-screening cylinder enters the seed-screening cylinder via the screw conveyor. The rotation of the seed-screening cylinder gradually sieves out the green manure seeds from the mixture, while the seed-grinding ball remains in the seed-screening cylinder. During the sieving process, the reverse-rotating screw conveyor acts as a barrier to prevent material from the seed-screening cylinder from returning to the seed-grinding cylinder. After the seed screening is completed, only the seed balls remain in the seed screening cylinder. The screw conveyor rotates forward again to send the seed balls back to the seed wiping cylinder. The feeding component then feeds the next batch of green manure seeds into the seed wiping cylinder for seed wiping. This cycle can be repeated to carry out batch seed wiping operations.

[0010] Furthermore, a first guide plate is fixed to the inner wall of the seed wiping cylinder, and the two ends of the first guide plate are offset circumferentially from the seed wiping cylinder. The first guide plate can guide the material in the seed wiping cylinder to the seed screening cylinder when it needs to enter the seed screening cylinder, preventing material from remaining in the seed wiping cylinder during the seed screening operation.

[0011] Furthermore, a second guide plate is fixed to the inner wall of the seed screening cylinder, with its two ends offset circumferentially from the seed screening cylinder. The second guide plate can guide the seed balls back into the seed wiping cylinder after screening, preventing them from remaining in the seed wiping cylinder.

[0012] Furthermore, the screw conveyor is fixed relative to the seed wiping cylinder and the seed screening cylinder. Thus, the screw conveyor rotates along with the seed wiping cylinder. When the screw conveyor needs to rotate forward, the seed wiping cylinder is controlled to rotate forward, and at this time, the second guide plate inside the seed screening cylinder guides the material inside towards the seed wiping cylinder. When the screw conveyor needs to rotate in reverse, the seed wiping cylinder is controlled to rotate in reverse, and at this time, the first guide plate inside the seed wiping cylinder guides the material inside towards the seed screening cylinder. This structure can reduce the number of motors, lower costs, and reduce control complexity.

[0013] Furthermore, the screw conveyor is driven by a separate drive mechanism to rotate relative to the seed wiping cylinder.

[0014] Furthermore, the feeding component includes a feeding hopper and an input mechanism. The input mechanism includes a seed conveying pipe, which is coaxially mounted with the seed wiping cylinder. The seed conveying pipe has a conveying auger inside and has an inlet and an outlet. The inlet is connected to the feeding hopper, and the outlet is located at the hopper. A feeding motor connected to the conveying auger is also mounted on the frame. By precisely driving the conveying auger to rotate a certain number of revolutions, the amount of green manure seeds fed into the seed wiping cylinder in each batch can be approximately equal.

[0015] Furthermore, the seed wiping cylinder is driven by a roller drive mechanism, which includes a roller drive motor and a drive roller. The drive roller contacts the cylinder wall of the seed wiping cylinder and has a rubber layer on its outer layer, which gives it a large frictional effect on the seed wiping cylinder. A drive pulley is fixed on the output shaft of the drive motor, and the drive roller and the drive pulley are connected by a belt.

[0016] There are two drive rollers, which are symmetrically installed relative to the seed wiping cylinder, which rests above the drive rollers. Furthermore, to provide sufficient support for the entire assembly of the seed wiping cylinder and the seed sieving cylinder, two driven rollers are symmetrically arranged below the seed sieving cylinder.

[0017] Furthermore, the seed wiping cylinder has a conical baffle at one end away from the seed sieving cylinder, and a first sealing strip is provided between the conical baffle and the seed wiping cylinder; the seed sieving cylinder has a side plate at one end away from the seed wiping cylinder, and a second sealing strip is provided between the side plate and the seed sieving cylinder; the side plate has a transparent observation window, through which the seed sieving situation inside the seed sieving cylinder can be easily observed to determine whether the seed sieving is complete.

[0018] Furthermore, the discharge component is a discharge hopper located on the lower side of the seed sieve cylinder.

[0019] Beneficial effects: The batch-type green manure seed wiping machine of the present invention has the following beneficial effects:

[0020] (1) The seed wiping cylinder and the seed screening cylinder are at both ends of a cylindrical tube, which can be used for two purposes. The structure is simple, the cost is low and the compactness is high. A screw conveyor is set between the seed wiping cylinder and the seed screening cylinder. The screw conveyor can transport materials between the two cylinders when materials need to be transported. On the other hand, it can prevent materials from entering the other cylinder when one cylinder is working. This makes the material management device between the seed wiping cylinder and the seed screening cylinder simple and easy to control. There is no need to set up a gate separately. The overall structure is compact and the volume is greatly reduced.

[0021] (2) Using a friction ball as a friction component, compared with a fixed friction component, since the friction ball is mixed with the green manure seeds, the friction ball can wipe all the green manure seeds in contact with it, which greatly improves the wiping efficiency. In addition, the friction ball and the green manure seeds enter the seed sieving cylinder together for sieving, and the separation of the friction ball and the seeds becomes simpler.

Detailed Implementation

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 1 The batch-type green manure seed wiping machine shown includes a frame 10, on which a feeding component 1, a wiping component 2, a sieving component, and a discharging component 4 are mounted. The wiping component 2 includes a cylindrical wiping cylinder 21 and wiping elements placed inside the wiping cylinder 21. The wiping cylinder 21 is rotatable relative to the frame 10. The sieving component is a sieving cylinder 3 connected to and coaxially arranged with the wiping cylinder 21. The outer surface of the sieving cylinder 3 has sieve holes 31, such as... Figure 5As shown, the sieve holes 31 are elongated holes, and their length extends along the circumference of the seed sieve cylinder 3, thus achieving a better seed sieving effect; for example... Figure 4 As shown, a screw conveyor 5 is installed at the connection between the seed wiping cylinder 21 and the seed screening cylinder 3. The maximum diameter of the screw conveyor 5 is equal to the inner diameter of the seed wiping cylinder 21 and the inner diameter of the seed screening cylinder 3.

[0031] like Figure 1 As shown, the discharge component 4 is a discharge hopper placed on the lower side of the seed sieve cylinder 3.

[0032] The seed-wiping component is a seed-wiping ball with an uneven surface. It can be a metal ball or a sand ball. When the seed-wiping ball is mixed with the green manure seeds and tumbles, it gradually removes the wax layer on the surface of the green manure seeds, thereby improving their water permeability and increasing the germination rate after sowing. The seed-wiping component can move within the seed-wiping cylinder 21 and can enter the seed-screening cylinder 3 via the screw conveyor 5.

[0033] like Figure 2 As shown, the seed wiping cylinder 21 has a conical baffle 23 at one end away from the seed screening cylinder 3, and a first sealing strip 24 is provided between the conical baffle 23 and the seed wiping cylinder 21; Figure 3 As shown, the seed screening cylinder 3 has a side plate 35 at the end away from the seed wiping cylinder 21. A second sealing strip 34 is provided between the side plate 35 and the seed screening cylinder 3. The side plate 35 has a transparent observation window 33. The seed screening situation inside the seed screening cylinder 3 can be easily observed through the observation window 33 to determine whether the seed screening is completed.

[0034] During the seed rubbing operation, the seed rubbing ball is located inside the seed sieve cylinder 3. The feeding component 1 feeds a batch of green manure seeds into the seed rubbing cylinder 21. Then, the seed rubbing cylinder 21 and the seed sieve cylinder 3 rotate synchronously, and the screw conveyor 5 rotates in the forward direction. At this time, the screw conveyor 5 can transport the material in the seed sieve cylinder 3 into the seed rubbing cylinder 21. Since there is no material in the seed sieve cylinder 3, the screw conveyor 5 does not play a role in transporting material at this time, but it can play a blocking role in preventing the material in the seed rubbing cylinder 21 from entering the seed sieve cylinder 3. In this way, the green manure seeds and the seed rubbing ball can rub against each other fully in the seed rubbing cylinder 21, and the wax layer on the surface of the green manure seeds is gradually rubbed off. After the seed wiping is completed (the time can be preset as the termination condition for determining whether seed wiping is complete), the screw conveyor 5 rotates in the reverse direction. At this time, the mixture of seed wiping balls and green manure seeds in the seed sieve cylinder 3 enters the seed sieve cylinder 3 through the screw conveyor 5. The rotation of the seed sieve cylinder 3 allows the green manure seeds in the mixture to be gradually sieved out, while the seed wiping balls remain in the seed sieve cylinder 3. During the sieving process, the reverse-rotating screw conveyor 5 can block the mixture and prevent the material in the seed sieve cylinder 3 from returning to the seed wiping cylinder 21. After the sieving is completed, the seed sieve cylinder 3 basically only contains seed wiping balls. The screw conveyor 5 rotates forward again to send the seed wiping balls back to the seed wiping cylinder 21. The feeding component 1 then feeds the next batch of green manure seeds into the seed wiping cylinder 21 for the seed wiping operation. This cycle can be repeated to perform batch seed wiping operations.

[0035] In the above structure, the seed wiping cylinder 21 and the seed screening cylinder 3 are located at opposite ends of a single cylinder, serving a dual purpose. This design is simple, low-cost, and highly compact. A screw conveyor 5 is installed between the seed wiping cylinder 21 and the seed screening cylinder 3. The screw conveyor 5 allows for material transport between the two cylinders when needed, and also prevents material from entering the other cylinder while one is operating. This simplifies and facilitates the material management between the seed wiping cylinder 21 and the seed screening cylinder 3, eliminating the need for a separate gate and resulting in a compact overall structure with significantly reduced volume. Furthermore, using friction balls as the friction component significantly improves efficiency compared to fixed friction components. Since the friction balls are mixed with the green manure seeds, they can wipe all the green manure seeds in contact with them, greatly increasing wiping efficiency. The friction balls and green manure seeds enter the seed screening cylinder 3 together for sieving, making separation of the friction balls from the seeds easier.

[0036] Preferably, a first guide plate 22 is fixed to the inner wall of the seed wiping cylinder 21, and the two ends of the first guide plate 22 are offset circumferentially from the seed wiping cylinder 21. The first guide plate 22 can guide the material in the seed wiping cylinder 21 to the seed screening cylinder 3 when it needs to enter the seed screening cylinder 3, preventing material from remaining in the seed wiping cylinder 21 during the screening operation. Similarly, a second guide plate 32 is fixed to the inner wall of the seed screening cylinder 3, and the two ends of the second guide plate 32 are offset circumferentially from the seed screening cylinder 3. The second guide plate 32 can guide the seed wiping balls in the seed screening cylinder 3 to the seed wiping cylinder 21 when they need to return after screening, preventing the seed wiping balls from remaining in the seed wiping cylinder 21.

[0037] In one embodiment, the screw conveyor 5 is fixed relative to the seed wiping cylinder 21 and the seed screening cylinder 3. Thus, the screw conveyor 5 rotates with the seed wiping cylinder 21. When the screw conveyor 5 needs to rotate forward, the seed wiping cylinder 21 is controlled to rotate forward, and at this time, the second guide plate 32 inside the seed screening cylinder 3 guides the material inside towards the seed wiping cylinder 21. When the screw conveyor 5 needs to rotate in reverse, the seed wiping cylinder 21 is controlled to rotate in reverse, and at this time, the first guide plate 22 inside the seed wiping cylinder 21 guides the material inside towards the seed screening cylinder 3. This structure can reduce the number of motors, lower costs, and reduce control difficulty. In the illustrated embodiment, the screw conveyor 5 is fixed relative to the seed wiping cylinder 21. In other embodiments, the screw conveyor 5 is driven by a separate drive mechanism to rotate relative to the seed wiping cylinder 21.

[0038] like Figure 6 As shown, the above-mentioned feeding component 1 includes a feeding hopper 11 and an input mechanism. The input mechanism includes a seed conveying pipe 12, which is coaxially mounted with the seed wiping cylinder 21. The seed conveying pipe 12 has a conveying auger 13 inside, and has an inlet 12a and an outlet 12b. The inlet 12a is connected to the feeding hopper 11, and the outlet 12b is located on the feeding hopper 11. A feeding motor 14, which is driven and connected to the conveying auger 13, is also installed on the seed conveying pipe 12. By precisely driving the conveying auger 13 to rotate a certain number of revolutions, the amount of green manure seeds fed into the seed wiping cylinder 21 in each batch can be approximately equal.

[0039] The seed wiping cylinder 21 is driven by a roller drive mechanism 6, which includes a roller drive motor 61 and drive rollers 62. The drive rollers 62 contact the cylinder wall of the seed wiping cylinder 21 and have a rubber layer on their outer surface, providing significant friction against the seed wiping cylinder 21. A drive pulley 63 is fixed to the output shaft of the drive motor 61, and a belt 64 establishes a transmission relationship between the drive rollers 62 and the drive pulley 63. There are two drive rollers 62, which are symmetrically installed relative to the seed wiping cylinder 21, which rests on top of the drive rollers 62. In addition, to provide sufficient support for the entire assembly of the seed wiping cylinder 21 and the seed sieving cylinder 3, two driven rollers 65 are symmetrically arranged below the seed sieving cylinder 3.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
