Description

A handle for a seeder Technical Field

[0001] This utility model belongs to the field of seeder technology, and specifically relates to a seeder handle. Background Technology

[0002] A seeder is a planting machine that sows crops or seeds. Seeders are characterized by uniform sowing, consistent depth, stable row spacing, good soil covering, seed saving, and high efficiency, making them more efficient than manual sowing. During the sowing process, the seeder requires buttons to control the feeding speed. Most existing seeders have these control buttons located on the handle for easy operator control. However, the buttons on the handle often require the operator to control the pressure applied to adjust the feeding speed, increasing the difficulty of button control and making it difficult to accurately control the feeding speed, significantly affecting the uniformity of sowing. Summary of the Invention

[0003] The purpose of this invention is to provide a handle for a seeder to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a handle for a seeder, comprising a handle body, a button movably mounted on the handle body, the button having a bracket, a movable component movably mounted on the bracket, the movable component being fixedly connected to a connecting band, the movable component having a locking block and a connecting arm, the connecting arm being elastically abutted against the bracket via a first spring, a knob movably mounted on the handle body, the knob being fixedly connected to a shaped wheel, the locking block being movably abutted against the shaped wheel, and a support arm on the handle body, the support arm being elastically abutted against the bracket via a second spring.

[0005] Preferably, the handle body is movably fitted with a locking button, and the locking button is provided with a latch.

[0006] Preferably, a micro switch is fixedly installed on the handle body.

[0007] Preferably, the knob is provided with a damping wheel, and the handle body is fixedly mounted with an elastic element. The elastic element is provided with a protrusion, and the protrusion movably abuts against the damping wheel.

[0008] Preferably, the knob is equipped with a scale, and the handle body is equipped with a pointer.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The button of this utility model is equipped with a bracket, on which a movable component is movably mounted. The movable component is fixed with a connecting belt, the other end of which is used to connect to the feeding switch inside the seeder. The movable component has a locking block and a connecting arm. The connecting arm elastically abuts against the bracket through a first spring. The bracket pushes the movable component to move through the first spring. A knob is movably mounted on the handle body. The knob is fixedly connected to a shaped wheel. The locking block movably abuts against the shaped wheel. The shaped wheel is spiral-shaped. By rotating the knob, the shaped wheel is driven, thereby adjusting the initial position of the locking block, and thus controlling the initial position of the movable component. The initial compression of the first spring is also adjusted. Since the bracket pushes the movable component to move through the first spring, the force of the button acting on the movable component is stabilized, the force of the connecting belt acting on the feeding switch is stabilized, the feeding speed of the seeder is stabilized, and the uniformity of sowing is improved.

[0019] 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.

[0020] Example 1:

[0021] As shown in Figures 1-7, the present invention provides a handle for a seeder, comprising a handle body 1. A button 2 is movably mounted on the handle body 1. The button 2 has a bracket 3. A movable component 4 is movably mounted on the bracket 3. The movable component 4 is fixedly connected to a connecting band 5. The movable component 4 has a locking block 6 and a connecting arm 7. The connecting arm 7 elastically abuts against the bracket 3 via a first spring 8. A knob 9 is movably mounted on the handle body 1. A shaped wheel 10 is fixedly connected to the knob 9. The locking block 6 movably abuts against the shaped wheel 10. The handle body 1 has a support arm 11, which elastically abuts against the bracket 3 via a second spring 12. A locking button 13 is movably mounted on the handle body 1, and the locking button 13 has a hook 14. A micro switch 15 is fixedly mounted on the handle body 1. The knob 9 has a damping wheel 16. An elastic component 17 is fixedly mounted on the handle body 1. The elastic component 17 has a protrusion 18, which movably abuts against the damping wheel 16. The knob 9 has a scale 19, and the handle body 1 has a pointer 20.

[0022] Through the above technical solution, the button 2 of this utility model is provided with a bracket 3, a movable part 4 is movably installed on the bracket 3, and a connecting belt 5 is fixed on the movable part 4. The other end of the connecting belt 5 is used to connect to the feeding switch inside the seeder. The movable part 4 is provided with a locking block 6 and a connecting arm 7. The connecting arm 7 is elastically abutted against the bracket 3 through a first spring 8. The bracket 3 pushes the movable part 4 to move through the first spring 8. The handle body 1 is movably installed with a knob 9, and a special-shaped wheel 10 is fixedly connected to the knob 9. The locking block 6 and the special-shaped wheel 10 are movably abutted. The special-shaped wheel 10 is spiral-shaped. By rotating the knob 9, the special-shaped wheel 10 is driven, thereby adjusting the initial position of the locking block 6, thereby controlling the initial position of the movable part 4 and adjusting the initial compression of the first spring 8. Since the bracket 3 pushes the movable part 4 to move through the first spring 8, the force of the button 2 on the movable part 4 is stabilized, the force of the connecting belt 5 on the feeding switch is stabilized, the feeding speed of the seeder is stabilized, and the uniformity of sowing is improved.

[0023] Example 2:

[0024] As shown in Figures 1-7, the handle body 1 of this utility model has a button 2 movably mounted on it. The button 2 has a bracket 3. The bracket 3 has a movable component 4 movably mounted on it. The movable component 4 is fixedly connected to a connecting strap 5. The movable component 4 has a locking block 6 and a connecting arm 7. The connecting arm 7 elastically abuts against the bracket 3 via a first spring 8. The handle body 1 has a knob movably mounted on it. The knob 9 is fixedly connected to a shaped wheel 10. The locking block 6 movably abuts against the shaped wheel 10. The handle body 1 has a support arm 11. The support arm 11 elastically abuts against the bracket 3 via a second spring 12.

[0025] During use, the operator holds the handle body 1 and presses button 2 with their finger. Button 2 moves, causing bracket 3 to move. The movement of bracket 3 pushes movable part 4 to move. Movable part 4 drives link 5 to move, and link 5 is connected to the feed switch of the seeder, thereby controlling the feed speed of the seeder. The locking block 6 on movable part 4 remains in contact with the irregularly shaped wheel 10. The irregularly shaped wheel 10 is spiral-shaped; as the knob 9 rotates, different parts of the irregularly shaped wheel 10 (each part has a different radius) contact the locking block 6, changing the initial position of movable part 4.

[0026] When button 2 is pressed, the second spring 12 is compressed. After button 2 is released, the second spring 12 pushes the bracket 3 upward, thereby causing button 2 to return to its original position. The first spring 8 connects the connecting arm 7 of the movable part 4 to the bracket 3, providing elastic thrust to the movable part 4 and keeping it in contact with the shaped wheel 10.

[0027] By adjusting knob 9, the contact position between the irregular wheel 10 and the locking block 6 is changed, thereby adjusting the initial position of the movable part 4 and the compression of the first spring 8. This adjustment mechanism makes the force exerted by button 2 on the movable part 4 more stable, thus achieving precise control of the feeding speed.

[0028] During the sowing operation, the operator can adjust the position of the irregularly shaped wheel 10 by rotating knob 9 to adjust the feeding speed as needed. After adjustment, each press of button 2 will produce the same feeding speed, ensuring uniform sowing. If it is necessary to change the feeding speed, simply adjust knob 9 again.

[0029] This design overcomes the drawback of traditional seeder handles that require precise operator control of pressing pressure. Through a coordinated mechanical structure, stable control of the force applied to button 2 is achieved, thereby improving sowing uniformity. Simultaneously, the adjustable mechanism allows the handle to be adapted to different seeds and sowing requirements, increasing the equipment's versatility.

[0030] Example 3:

[0031] As shown in Figures 1-7, a locking button 13 is movably mounted on the handle body 1 of this utility model. The locking button 13 has a latch 14. During use, the operator holds the handle body 1 and presses the button 2 to control the feed of the seeder. When continuous sowing for a long period is required, the operator can use the locking button 13 to fix the button 2, avoiding fatigue caused by prolonged forceful pressing of the button 2.

[0032] The specific operating method is as follows: First, the operator fully presses button 2 to its lowest position. Then, the operator pushes the locking button 13, causing the hook 14 on the locking button 13 to engage with the corresponding structure on button 2. At this time, even if the operator releases button 2, button 2 will remain pressed, continuing to control the seeder to feed material.

[0033] When it is necessary to stop sowing or change the feeding speed, the operator pushes the locking button 13 again to separate the hook 14 from the button 2. At this time, under the action of the second spring 12, the button 2 will automatically spring back to the initial position and stop feeding.

[0034] This locking mechanism significantly improves the operator's comfort during extended operation. Operators no longer need to continuously press button 2, reducing hand fatigue and increasing work efficiency. Simultaneously, the locking mechanism ensures stable material feeding speed in the locked state, further enhancing the uniformity of seeding.

[0035] The locking button 13 is designed to be simple and easy to use. The operator can lock or unlock it with a gentle push, without increasing the complexity of the operation. Moreover, the addition of the locking button 13 does not affect other functions of the handle, and the operator can still change the feeding speed by adjusting the knob 9.

[0036] In practical applications, this seeder handle with a locking function is particularly suitable for sowing operations in large-area farmland. The operator can lock button 2 when starting to sow a row or a section of land, and unlock it after completion, which ensures the continuity of sowing and reduces operator fatigue.

[0037] In addition, the locking function provides operators with more operational freedom. For example, after locking button 2, the operator can free up their hands to adjust other parts of the seeder or deal with problems encountered during the seeding process without worrying about interrupting the seeding.

[0038] Example 4:

[0039] As shown in Figures 1-7, a micro switch 15 is fixedly installed on the handle body 1 of this utility model. The micro switch 15 is an electrical switch used to control the electrical components inside the seeder. The state of the micro switch 15 is synchronized with the state of the button 2. When the button 2 is initially pressed, the support 3 of the button 2 presses against the micro switch 2; however, after the button 2 is pressed, the micro switch 15 is released. During use, when the operator presses the button 2, not only will the moving part 4 drive the connecting part 5 to move to control the mechanical feeding device, but the micro switch 15 will also be triggered. The triggering of the micro switch 15 can control the electric feeding device, counter, or other electrical components inside the seeder.

[0040] Example 5:

[0041] As shown in Figures 1-7, the knob 9 of this invention is equipped with a damping wheel 16. The damping wheel 16 has a disc-shaped structure with uniformly spaced arc-shaped notches on its surface and is fixedly installed on the inner side of the knob 9. An elastic element 17 is fixedly installed on the handle body 1. The elastic element 17 is made of elastic metal sheet or plastic and has an arc-shaped structure. Both ends of the elastic element 17 are fixed to the inner wall of the handle body 1, while the middle section is suspended, providing elasticity. A protrusion 18 is provided in the middle section of the elastic element 17. The protrusion 18 is hemispherical and abuts against the arc-shaped notch of the damping wheel 16. When the knob 9 is rotated, the damping wheel 16 rotates accordingly. The protrusion 18 abuts against the surface of the damping wheel 16 and engages with the arc-shaped notch to keep the knob 9 in its current position and prevent accidental rotation. This also improves the feel of the knob 9 when rotating.

[0042] Example 6:

[0043] As shown in Figures 1-7, the knob 9 of this invention has a scale 19 around its outer periphery. The scale 19 surrounds the knob 9 and is marked with either engraving or embossing. The scale lines are evenly distributed, and the interval between each scale represents a certain adjustment amount. Next to each scale is a corresponding number or symbol indicating different adjustment levels or specific adjustment values. A pointer 20 is provided on the handle body 1, located on the side of the knob 9, near the scale 19. The pointer 20 has a raised, triangular shape, with its tip facing the scale 19. The color of the pointer 20 contrasts with the surrounding structure for easy identification. The pointer 20 remains stationary, while the scale 19 rotates with the knob 9. When the operator rotates the knob 9, the scale 19 rotates accordingly. By observing the scale position indicated by the pointer 20, the operator can intuitively understand the current adjustment status. This design makes the adjustment process more intuitive and precise. The operator does not need to judge the degree of adjustment by feel but can directly make quantitative adjustments based on the scale.
