Description

Technical Field

[0001] This utility model belongs to the field of yam cultivation technology, specifically relating to a directional output device for yam seed tubers. Background Technology

[0002] Yam, also known as Chinese yam, is a plant belonging to the genus Dioscorea in the family Dioscoreaceae. It is a twining herbaceous vine. Its tubers are rich in starch and can be eaten as a vegetable.

[0003] Yam tubers are long and cylindrical, growing vertically. Planting typically utilizes the section with a bud at the top of the rhizome as the "root tip." After deep loosening of the soil, the long, stem-like root tip is placed horizontally in the furrow. During planting, to ensure successful germination and growth, the narrower end of each yam tuber should be facing upwards. This planting process usually requires manual adjustment. When planting a large number of yam tubers, the prolonged adjustment leads to excessive labor intensity for growers, resulting in decreased planting efficiency. Therefore, a specialized yam planting machine is needed to replace manual planting and improve labor efficiency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a directional output device for yam seed tubers, which solves the technical problem of manually adjusting the orientation of the ends of yam seed tubers during planting.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A directional output device for yam seed tubers, comprising:

[0007] The material discharge bin has a feed inlet and a discharge outlet that are staggered in the vertical direction at its top and bottom, respectively.

[0008] A directional switching component is slidably connected inside the material discharge bin and can reciprocate horizontally under the drive of the pushing component.

[0009] The directional switching component includes a clamping base, an arc-shaped clamping piece, a clamping and releasing component, and a locking component. Initially, the arc-shaped clamping piece is spaced apart from the clamping base. The arc-shaped clamping piece can move towards the clamping base under the action of the pushing component, thus cooperating with the clamping base to form a clamping and conveying mechanism.

[0010] The clamping and releasing component is used to retract the arc-shaped clamping piece that receives the yam seed block (smaller at the top and larger at the bottom), thereby releasing the clamp on the yam seed block. The locking component is used to maintain the clamping between the clamping base that receives the yam seed block (larger at the top and smaller at the bottom) and the arc-shaped clamping piece.

[0011] The material feeding bin is equipped with an unlocking component that works in conjunction with the locking assembly. When the yam seed block rotates, the locking assembly can be controlled to unlock, thereby releasing the clamped yam seed block.

[0012] Furthermore, the clamping and releasing assembly includes a sleeve bracket, a mounting bracket, and a lever fastener. The sleeve bracket is fixed to the drive end of the pushing assembly. The mounting bracket is slidably engaged with the sleeve bracket. The lever fastener is rotatably connected to the mounting bracket. In the initial state, the lever fastener abuts against the locking part of the locking assembly. The outer wall of the arc-shaped clamp is provided with a connector that mates with the lever fastener. The connector is rotatably engaged with the mounting bracket, enabling the lever fastener to disengage from the locking part of the locking assembly during rotation.

[0013] Furthermore, the locking assembly includes a locking lever and an unlocking control assembly. A support bracket is provided at the bottom of the mounting bracket. A second spring is mounted on the support bracket to cooperate with the locking lever. The inner end of the locking lever is rotatably connected to the sleeve bracket and initially abuts against the latching member under the drive of the second spring. The unlocking control assembly can disengage the locking lever from the latching member when it abuts against the unlocking member.

[0014] Furthermore, the unlocking control assembly includes an unlocking lever and a transmission component. The unlocking lever is rotatably connected to the mounting bracket and is connected to the locking lever via the transmission component. The unlocking component is a wedge-shaped block with an inclined surface on one side. The unlocking lever can cause the locking lever to separate from the lever when it comes into contact with the unlocking component.

[0015] Furthermore, the pushing component includes a guide rod, a limiting support, and a displacement driving component. Both the guide rod and the sleeve bracket are fixed to the driving end of the displacement driving component. The guide rod passes through the clamping base and slides with it. The limiting support is fixed to the guide rod and is initially spaced apart from the clamping base.

[0016] Furthermore, a first spring is provided between the clamping base and the discharge bin. A limiting block is provided at the opening of the discharge bin to limit the outward extreme position of the clamping base.

[0017] Furthermore, the displacement driving assembly includes a limiting support, a pushing drive component, a pushing bracket, and a drive motor. The pushing drive component is rotatably connected to the limiting support and can rotate under the drive of the drive motor. The pushing bracket is slidably engaged with the pushing drive component, allowing it to reciprocate horizontally during the rotation of the pushing drive component and rotate when it reaches its extreme outward position. The guide rod and the sleeve bracket are both fixed to the outer end of the pushing bracket.

[0018] Furthermore, an arc-shaped groove is formed on the outer wall of the pushing drive component. A limiting groove corresponding to the arc-shaped groove is formed on the limiting support. A transmission bracket is fixed on the pushing bracket. The outer end of the transmission bracket passes through the arc-shaped groove and extends into the limiting groove. The limiting groove is divided into a horizontal section and a ring-shaped rotating section.

[0019] Furthermore, a tension spring is provided between the mounting bracket and the sleeve bracket. A limiting bracket that cooperates with the arc-shaped clamping piece is provided on the outer side of the clamping base.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention features spaced-apart arc-shaped clamping pieces and a clamping base. A clamping-releasing component and a locking component control the clamping and retraction of the arc-shaped clamping pieces. When receiving yam seed blocks that are smaller at the top and larger at the bottom, the arc-shaped clamping pieces retract under the action of the clamping-releasing component, releasing the clamp on the yam seed block. When receiving yam seed blocks that are larger at the top and smaller at the bottom, the locking component maintains the clamping. As the yam seed block rotates, the unlocking component releases the clamp on the yam seed block, achieving directional output of the yam seed block, reducing the need for manual adjustment, and improving planting efficiency while reducing the labor intensity of growers.

Detailed Implementation

[0029] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1 and 2 As shown, a directional output device for yam seed tubers includes a feeding bin 1, a directional switching component 2, and a pushing component 3. The feeding bin 1 has an inlet 1-1 at its top and an outlet 1-2 at its bottom. The inlet 1-1 and outlet 1-2 are staggered vertically. The directional switching component 2 is slidably connected within the feeding bin 1 and can reciprocate horizontally under the drive of the pushing component 3.

[0032] The directional switching component 2 includes a clamping base 4, an arc-shaped clamping piece 5, a clamping and releasing component 6, and a locking component 7. The clamping base 4 is slidably connected within the material discharge bin 1, and a first spring 8 is provided between it and the inner wall of the material discharge bin 1. The clamping base 4 has an arc-shaped clamping groove that cooperates with the arc-shaped clamping piece 5 to form a clamping cavity that matches the conveyed yam seed blocks. When the yam seed blocks enter from the feed inlet 1-1, they fall into the clamping cavity, and the clamping base 4 and the arc-shaped clamping piece 5 clamp the falling yam seed blocks.

[0033] When the yam seed block falls into the clamping cavity with its top smaller than its bottom, the arc-shaped clamping piece 5 retracts under the drive of the clamping and releasing component 6, creating a gap between the arc-shaped clamping piece 5 and the clamping base 4. When the arc-shaped clamping piece 5 and the clamping base 4 move to the position of the discharge port 1-2 under the drive of the pushing component 3, the yam seed block is output from the discharge port 1-2 under the action of gravity. When the yam seed block falls into the clamping cavity with its top larger than its bottom, the clamping and releasing component 6 is locked by the locking component 7. The arc-shaped clamping piece 5 and the clamping base 4 clamp the yam seed block. The discharge bin 1 is provided with an unlocking component 15 that cooperates with the locking component 7. When the arc-shaped clamping piece 5 and the clamping base 4 move to the inner end of the discharge bin 1 under the drive of the pushing component 3 and rotate, the locking component 7 releases the lock on the clamping and releasing component 6 with the cooperation of the unlocking component 15. When the yam seed block rotates to a position where it is smaller at the top and larger at the bottom, the arc-shaped clamp 5 is released from locking the yam seed block by the clamping and releasing component 6, allowing the yam seed block to be smoothly output from the discharge port 1-2.

[0034] The specific structure is as follows: Figure 2 and 3 As shown, the clamping and releasing assembly 6 includes a sleeve bracket 6-1, a mounting support 6-2, and a lever fastener 6-3. The sleeve bracket 6-1 is fixed to the drive end of the pushing assembly 3 and can reciprocate horizontally under the drive of the pushing assembly 3. The mounting support 6-2 is slidably engaged with the sleeve bracket 6-1. The lever fastener 6-3 is rotatably connected to the end of the mounting support 6-2. In the initial state, the lever fastener 6-3 abuts against the locking part of the locking assembly 7, thereby locking the sliding contact between the mounting support 6-2 and the sleeve bracket 6-1.

[0035] The outer wall of the arc-shaped clamp 5 is provided with a connecting piece 9 that mates with the latch 6-3. The connecting piece 9 is rotatably engaged with the mounting support 6-2. When the arc-shaped clamp 5, driven by the pushing component 3, abuts against the yam seed block (smaller at the top and larger at the bottom), the arc-shaped clamp 5 drives the connecting piece 9 to rotate. The outer end of the connecting piece 9 drives the latch 6-3 to rise upward, disengaging from the locking part of the locking component 7, allowing the mounting support 6-2 and the sleeve bracket 6-1 to slide relative to each other. The position of the clamping base 4 is limited by the pushing component 3, thereby unlocking the clamping of the yam seed block and allowing it to be smoothly output from the discharge port 1-2 under the action of gravity.

[0036] In this embodiment, a tension spring 10 is provided between the mounting bracket 6-2 and the sleeve bracket 6-1. When the buckle 6-3 disengages from the locking part of the locking assembly 7, the mounting bracket 6-2 can slide inward towards the sleeve bracket 6-1 under the pull of the tension spring 10, thereby releasing the clamping of the yam seed block. Furthermore, a limiting bracket 11 is provided on the outer side of the clamping base 4 to cooperate with the arc-shaped clamp 5. The limiting bracket 11 is used to limit the maximum distance of the arc-shaped clamp 5's retraction, preventing the arc-shaped clamp 5 from disengaging from the clamping base 4. When the arc-shaped clamp 5 in the unlocked state abuts against the limiting bracket 11, the pushing assembly 3 drives the sleeve bracket 6-1 to continue retracting, causing the sleeve bracket 6-1 and the mounting bracket 6-2 to move in opposite directions. During the reverse movement, the buckle 6-3 on the mounting bracket 6-2 falls back down and abuts against the locking part of the locking assembly 7, realizing the reset locking between the sleeve bracket 6-1 and the mounting bracket 6-2.

[0037] like Figure 4 and 5 As shown, the locking assembly 7 includes a locking lever 7-1, an unlocking lever 7-2, and a transmission component 7-3. The bottom of the mounting bracket 6-2 is provided with an integrally formed support bracket. The support bracket is equipped with a second spring 12 that cooperates with the locking lever 7-1. The inner end of the locking lever 7-1 is rotatably connected to the sleeve bracket 6-1, and initially, under the drive of the second spring 12, it abuts against the lever 6-3, thereby locking the sleeve bracket 6-1 against the mounting bracket. The unlocking lever 7-2 is rotatably connected to the top of the mounting bracket and is connected to the locking lever 7-1 via the transmission component 7-3. When the unlocking lever 7-2 is pressed down in cooperation with the unlocking component 15 within the discharge bin 1, it will drive the locking lever 7-1 to press down synchronously via the transmission component 7-3, thereby unlocking the lever 6-3. In this embodiment, the unlocking component 15 is a wedge-shaped block with an inclined surface on one side.

[0038] like Figure 2 and 6 As shown, the pushing component 3 includes a guide rod 3-1, a limiting support 3-2, and a displacement driving component. Both the guide rod 3-1 and the sleeve bracket 6-1 in the clamping and releasing component 6 are fixed to the driving end of the displacement driving component, enabling them to reciprocate horizontally under the drive of the displacement driving component. The guide rod 3-1 passes through the clamping base 4 and slides against it. The limiting support 3-2 is fixed to the guide rod 3-1 and initially spaced apart from the clamping base 4.

[0039] During operation, when the guide rod 3-1 and the clamping and releasing assembly 6 move towards the clamping base 4 under the drive of the displacement drive assembly, the clamping and releasing assembly 6 will first drive the arc-shaped clamping piece 5 towards the clamping base 4, thereby clamping the yam seed block that has fallen into the clamping cavity. Next, the limiting support 3-2, driven by the guide rod 3-1, gradually abuts against the clamping base 4 and drives it to move synchronously, achieving the conveying operation while the yam seed block is clamped. The first spring 8 is gradually compressed during the movement of the clamping base 4. When the arc-shaped clamping piece 5 retracts under the drive of the clamping and releasing assembly 6, the clamping base 4 can be limited and supported by the limiting support 3-2, achieving the opposite movement of the clamping base 4 and the arc-shaped clamping piece 5, thus completing the release of the clamped yam seed block.

[0040] In this embodiment, a limiting block 16 is provided at the opening of the material discharge bin 1. When the clamping base 4 moves to its outermost end under the push of the first spring 8, its position can be limited by the limiting block 16. The clamping and releasing assembly 6 continues to move outward under the drive of the displacement driving assembly. The position of the arc-shaped clamping piece 5 is limited by the limiting support 3-2 on the clamping base 4, so that the mounting support 6-2 in the clamping and releasing assembly 6 is subjected to the tension of the arc-shaped clamping piece 5. Under the action of the tension, the mounting support 6-2 moves in the opposite direction to the sleeve support, thereby realizing the reset and locking of the buckle 6-3 on the mounting support 6-2.

[0041] The displacement drive assembly includes a limiting support 3-4, a pushing drive component 3-5, a pushing bracket 3-6, and a drive motor. The limiting support 3-4 has a mounting groove that mates with the pushing drive component 3-5. The pushing drive component 3-5 is rotatably connected within the mounting groove and can rotate under the drive of the drive motor. The pushing drive component 3-5 has a sliding groove that mates with the pushing bracket 3-6. The pushing bracket 3-6 is slidably connected within the sliding groove and can reciprocate horizontally during the rotation of the pushing drive component 3-5, rotating further outward to its limit position. The guide rod 3-1 and the sleeve bracket 6-1 are both fixed to the outer end of the pushing bracket 3-6 and can move synchronously under the drive of the pushing bracket 3-6.

[0042] The specific structure is as follows: Figure 6As shown, an arc-shaped slot 13 is formed on the outer wall of the push drive component 3-5. A limiting groove 14 corresponding to the arc-shaped slot 13 is formed on the limiting support 3-4. A transmission support 3-7 is fixed on the push bracket 3-6. The outer end of the transmission support 3-7 passes through the arc-shaped slot 13 and extends into the limiting groove 14. The limiting groove 14 is divided into a horizontal section 14-1 and a ring-shaped rotating section 14-2. When the push drive component 3-5 rotates and the transmission support 3-7 is located in the horizontal section 14-1, the transmission support 3-7 is driven to move horizontally through the cooperation between the arc-shaped slot 13 and the horizontal section 14-1 of the limiting groove 14, thereby driving the push bracket 3-6 to move horizontally. When the transmission support 3-7 enters the rotating section 14-2 from the horizontal section 14-1, the transmission support 3-7 can rotate under the drive of the push drive component 3-5, thereby driving the push bracket 3-6 to rotate.

[0043] When the push drive component 3-5 moves in the opposite direction under the drive motor, and drives the transmission bracket 3-7 to the slot position of the horizontal section 14-1, the first spring 8 inside the clamping base 4 pushes it back to its original position. The drive guide rod 3-1 and the push bracket 3-6 move in the opposite direction in the horizontal direction, thereby pushing the transmission bracket 3-7 on the push bracket 3-6 into the horizontal section 14-1, and moving to the innermost end under the continuous rotation of the push drive component 3-5.

[0044] The working principle of this utility model is as follows:

[0045] During operation, when the yam seed block, which is smaller at the top and larger at the bottom, falls into the clamping cavity, the drive motor in the pushing assembly 3 drives the pushing drive component 3-5 to rotate. The pushing bracket 3-6, driven by the transmission bracket 3-7, moves outward horizontally, pushing the guide rod 3-1 and the clamping release assembly 6 towards the clamping base 4. The arc-shaped clamping piece 5 moves towards the clamping base 4 under the drive of the clamping release assembly 6. When the arc-shaped clamping piece 5 comes into contact with the yam seed block during its movement, it drives the connecting piece 9 to rotate. The outer end of the connecting piece 9 drives the buckle 6-3 to rise, disengaging it from the locking rod 7-1 in the locking assembly 7, allowing the mounting support 6-2 and the sleeve bracket 6-1 to slide relative to each other. The arc-shaped clamping piece 5 retracts under the pull of the mounting support 6-2, creating a gap between the arc-shaped clamping piece 5 and the clamping base 4, thus releasing the clamp on the yam seed block. When the arc-shaped clamping piece 5 and the clamping base 4 move to the position of the discharge port 1-2 under the drive of the pushing component 3, the yam seed block is output from the discharge port 1-2 under the action of gravity.

[0046] When the yam seed block falls into the clamping cavity with its top larger than its bottom, the drive motor in the pushing assembly 3 drives the pushing drive component 3-5 to rotate. The pushing bracket 3-6, driven by the transmission bracket 3-7, moves outward horizontally, thereby pushing the guide rod 3-1 and the clamping and releasing assembly 6 towards the clamping base 4. The clamping and releasing assembly 6 first drives the arc-shaped clamping piece 5 towards the clamping base 4, thus clamping the yam seed block that has fallen into the clamping cavity. Next, the limiting support component 3-2, driven by the guide rod 3-1, gradually comes into contact with the clamping base 4 and moves synchronously thereafter, achieving the conveying operation while the yam seed block is clamped.

[0047] When the arc-shaped clamping piece 5 and the clamping base 4 move to their ends and rotate under the drive of the pushing bracket 3-6, they will switch the yam seed block from a top-large to a bottom-small state. Simultaneously, the unlocking lever 7-2 on the sleeve bracket 6-1, in cooperation with the unlocking component 15 in the discharge bin 1, presses down. This, through the transmission component 7-3, drives the locking rod 7-1 to press down synchronously, thereby unlocking the lever 6-3. This allows relative sliding between the mounting support 6-2 and the sleeve bracket 6-1. The arc-shaped clamping piece 5 retracts under the pull of the mounting support 6-2, creating a gap between the arc-shaped clamping piece 5 and the clamping base 4, releasing the clamp on the yam seed block. The yam seed block is then discharged from the discharge port 1-2 under gravity.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
