Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a bud-setting and sowing mechanism and a sowing method thereof. Background Art

[0002] The agricultural machinery industry is currently developing rapidly, and the level of agricultural mechanization is increasing. Garlic is one of China's major specialty cash crops, but traditional garlic planters rarely meet the agronomic requirement of planting garlic bulbs with the bulbs facing upward. This is crucial for garlic's growth and development.

[0003] When sowing garlic, the bulbils may face downward, upward, or randomly. The garlic seeds can all germinate smoothly. However, when the bulbils face downward or randomly, the germination period is longer, the sprouting leaves emerge slowly and are weak, and the emergence is uneven. During the growth period, the garlic plants with the bulbils facing downward or randomly sown are shorter and have smaller leaf area. The garlic bulbs with the bulbils facing downward or randomly sown are lighter and have a smaller horizontal diameter. The growth posture of the garlic underground is consistent with the posture of the garlic seeds at sowing. When the garlic seeds with the bulbils facing randomly or downward sown germinate, the buds grow curved upward and the roots grow downward. When harvested, the garlic bulbs are inverted or lying flat underground.

[0004] Therefore, it is necessary to design a mechanism that can make the garlic bulbs face upwards before sowing. Summary of the Invention

The two sides of the semi-conical shells without push rods in each conical shell group are hinged to one end of the two connecting rods 1, and the two sides of the semi-conical shells with push rods are hinged to one end of the two connecting rods 2. The other ends of the connecting rods 1 and 2 on the same side of each conical shell group are hinged to a slider, and each slider forms a sliding pair with the slide rail on the same side. The semi-conical shells are made of transparent material, and the interiors of the two conical shell groups are hollow to form a seed storage space. In the initial state, the two semi-conical shells in each conical shell group are in a closed state.

[0011] The upper stopper is fixed on the frame and is located above all rotating devices, the lower stopper is fixed on the frame and is located below all rotating devices, the flip stopper is driven by the driving member to move horizontally and is located in front of all rotating driving devices, and the visual recognition device is arranged on the frame.

[0012] Preferably, the driving member includes a linear module and a push rod. The linear module is fixed on the frame and driven by a drive motor. One end of the push rod is fixed to the slider 2 of the linear module, and the other end is fixed to the flip stopper.

[0013] Preferably, a pushing sleeve is sleeved on one end of the push shaft passing through the U-shaped groove, and the end of the pushing sleeve away from the cam roller is connected to the adjacent pulley through a spring, and the end of the pushing sleeve close to the cam roller is provided with an integrally formed ball head, and the ball head and the cam groove constitute a cam pair; wherein the spring is in a compressed state.

[0014] The present invention provides a sowing method for a bud-forming and sowing mechanism, which is specifically as follows:

[0015] External power drives the frame forward and drives the central shaft to rotate wheel one and wheel two, and then drives wheel three to rotate through each connecting rod. According to the translational characteristics of the parallelogram mechanism, each connecting rod only undergoes translation relative to the ground during movement, and does not rotate, and always remains in a horizontal state, so that the cam rollers in each bud correction device are always in a translational state when not performing bud correction work.

[0016] The two push rods move upward along the corresponding slide rails through the two connecting rods 2, and the two slides 1 push the corresponding semi-conical shells to rotate forward through the two connecting rods 1. The upper conical shell group in the bud-correcting device opens, and the corresponding two tension springs 2 are stretched; then a garlic seed is put into the seed storage space of the bud-correcting device; then, as the central axis rotates, the two push rods at the top are disengaged from the upper stopper, and due to the restoring force of the tension spring 2, the two semi-conical shells at the top move toward each other to close, and push the slide 1 downward to its original position through the corresponding connecting rod 1 and connecting rod 2.

[0017] The visual recognition device determines the status of the garlic bulbs in the seed storage space of the bud-forming device containing the garlic seeds. If the visual recognition device detects that the garlic bulbs in the seed storage space are facing downward, the driving member drives the flip block to move backward a preset distance. As the central axis rotates, the push shaft in the bud-forming device containing the garlic seeds and the bulbs facing downward contacts the flip block. The flip block gives the push shaft a thrust, but due to the blocking effect of the corresponding one-way block, the push shaft cannot move in the direction of the horizontal groove one or the horizontal groove two rotation device, and then the push shaft moves in the direction of the spiral groove one or the spiral groove two rotation device, driving the cam roller to rotate relative to the rotating shaft. The connecting plate integrally formed on the cam roller drives the rotation device to rotate, and the tension spring is stretched until the push shaft moves to the horizontal groove The cam roller drives the rotating device to rotate 180°, causing the garlic seeds in the seed storage space to change from bulbils facing downward to bulbils facing upward. As the central axis rotates, the push shaft disengages from the flip block. Due to the restoring force of tension spring 1, tension spring 1 pulls the push shaft along horizontal slot 2 or horizontal slot 1 toward the connecting frame. The push shaft contacts the one-way block and pushes the one-way block to rotate upward until the push shaft disengages from the one-way block and moves to the end of horizontal slot 2 or horizontal slot 1 near the connecting frame. Then, due to the restoring force of the torsion spring, the one-way block rotates downward to its original position, completing the bud alignment. If the visual recognition device detects that the garlic seeds in the seed storage space are bulbs facing upward, the drive member will not operate.

[0018] As the central axis continues to rotate, when the two push rods at the bottom of the bud-forming device with garlic seeds and garlic bulbs facing upward or the bud-forming work is completed come into contact with the lower block, the lower block pulls the two push rods to rotate forward, and the two push rods drive the corresponding semi-conical shells to rotate forward, and then pull the two sliders one along the corresponding slide rails through the corresponding two connecting rods two, thereby pushing the corresponding semi-conical shells to rotate backward through the two connecting rods one, and the conical shell group at the bottom opens, and the corresponding two tension springs two are stretched; then the garlic seeds with bulbs facing upward fall from the seed storage space into the pre-dug pit; then as the central axis rotates, the two push rods at the bottom disengage from the lower block, and due to the restoring force of the tension spring two, the two semi-conical shells at the bottom move toward each other to close, and push the slider one upward to its original position through the connecting rod one and the connecting rod two.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention can not only realize the bud-setting function by driving the rotating device to rotate 180 degrees through the rotating driving device, but also realize the sowing function through the lower block. Specifically, after the two push rods at the top of a bud-setting device without garlic seeds come into contact with the upper block, the upper block pushes the two push rods to drive the corresponding semi-conical shell in the upper conical shell group to rotate backward, and drives the other semi-conical shell in the upper conical shell group forward through connecting rod 1, slider 1 and connecting rod 2, thereby realizing the opening of the upper conical shell group in the bud-setting device; after the garlic seeds fall into the seed storage space, the visual recognition device is used to determine the state of the garlic seed bulbs; when the garlic seed bulbs are facing downward, the driving member drives the flip block to extend, and the push shaft in the bud-setting device with garlic seeds and bulbs facing downward comes into contact with the flip block, and the flip block pushes the push shaft along the spiral groove The first or the second spiral groove moves, thereby driving the cam roller to rotate 180 degrees, thereby driving the rotating device to rotate 180 degrees, and the garlic seeds change from a state with the bulbils facing downward to a state with the bulbils facing upward, thereby realizing the correct bud function; after the two push rods at the bottom of the correct bud device, which is equipped with garlic seeds and the garlic seed bulbs facing upward or has completed the correct bud work, come into contact with the lower block, the lower block pulls the two push rods to drive the corresponding semi-conical shell in the conical shell group below to rotate backward, and drives the other semi-conical shell in the conical shell group below to move forward through the connecting rod 1, the slider 1 and the connecting rod 2, thereby realizing the opening of the conical shell group at the bottom in the correct bud device, and the garlic seeds with the bulbils facing upward fall into the pit, thereby realizing the sowing function.

[0021] 2. The present invention uses the parallelogram's translational characteristics to ensure that each connecting rod always maintains translational motion during the rotation process, thereby ensuring that the cam roller of the rotation drive device in each bud-correcting device always maintains translational motion when the bud-correcting operation is not in progress. Moreover, due to the limiting effect of each rotation drive device, the cam roller in each bud-correcting device does not rotate when the conical shell group is opened, thereby increasing the stability of transportation.

[0022] 3. The present invention realizes the integrated functions of transportation, sprouting and sowing of garlic seeds after inoculation, and has low driving energy and energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The driving motor 15 is controlled by a controller, and the signal output terminal of the visual recognition device 8 is connected to the controller.

[0040] The present invention provides a sowing method for a bud-forming and sowing mechanism, which is specifically as follows:

[0041] External power drives the frame forward and drives the central shaft 4 to rotate the wheel disc 1 3 and the wheel disc 2 9, and then drives the wheel disc 3 10 to rotate through each connecting rod 12. According to the translational characteristics of the parallelogram mechanism, each connecting rod 12 only undergoes translation relative to the ground during movement, and does not rotate, and always maintains a horizontal state, so that the cam roller 29 in each bud correction device 2 is always in a translational state when not performing bud correction work.

[0042] As the central shaft 4 rotates, when the two push rods 16 at the top of one of the bud-forming devices 2 without garlic seeds come into contact with the upper block 1, the upper block 1 prevents the two push rods 16 from continuing to rotate forward, thereby pushing the two push rods 16 to rotate backward. The two push rods 16 drive the corresponding semi-conical shells 23 to rotate backward, and then pull the two sliders 1 20 along the corresponding slide rails 22 upward through the two connecting rods 1 19. The two sliders 1 20 push the corresponding semi-conical shells 23 to rotate forward through the two connecting rods 1 18. The cone shell group at the top of the bud-forming device 2 opens, and the corresponding two tension springs 17 are stretched. Figure 7 As shown; then, a garlic seed is dropped into the seed storage space of the bud-forming device 2 (the garlic seed can be dropped manually or by a seed-dropping mechanism); then, as the central shaft 4 rotates, the two push rods 16 located above are disengaged from the upper block 1, and due to the restoring force of the tension spring 2 17, the two semi-conical shells 23 located above move toward each other to close, and push the slider 1 20 downward to its original position through the corresponding connecting rod 1 18 and connecting rod 2 19.

[0043] The visual recognition device 8 determines the state of the garlic bulbs in the seed storage space of the bud device 2 containing garlic seeds. If the visual recognition device 8 detects that the garlic bulbs in the seed storage space are facing downward, the driving member 6 drives the flip block 7 to move backward a preset distance. As the central shaft 4 rotates, the push shaft 35 in the bud device 2 containing garlic seeds and bulbs facing downward contacts the flip block 7. The flip block 7 gives the push shaft 35 a thrust, but due to the blocking effect of the corresponding one-way block 32, the push shaft 35 cannot move in the direction of the horizontal groove 1 or horizontal groove 2 rotation device, thereby causing the push shaft 35 to move in the direction of the spiral groove 1 or spiral groove 2 rotation device, driving the cam roller 29 to rotate relative to the rotating shaft 30. The connecting plate integrally formed on the cam roller 29 drives the rotating device to rotate, and the tension spring 1 27 is stretched until the push shaft 35 moves to the horizontal groove When the central shaft 4 rotates, the push shaft 35 disengages from the flip block 7. Due to the restoring force of the tension spring 1 27, the tension spring 1 27 pulls the push shaft 35 along the horizontal groove 2 or horizontal groove 1 toward the connecting frame. The push shaft 35 contacts the one-way block 32 and pushes the one-way block 32 to rotate upward until the push shaft 35 disengages from the one-way block 32 and moves to the end of the horizontal groove 2 or horizontal groove 1 near the connecting frame. Then, due to the restoring force of the torsion spring 31, the one-way block 32 rotates downward to its original position, completing the bud alignment. If the visual recognition device 8 detects that the garlic seed bulbs in the seed storage space are facing upward, the drive member 6 will not operate.

[0044] As the central shaft 4 continues to rotate, when the two push rods 16 at the bottom of the bud-forming device 2, which is loaded with garlic seeds and with the bulbs facing upward or has completed the bud-forming work, come into contact with the lower block 5, the lower block 5 pulls the two push rods 16 to rotate forward, and the two push rods 16 drive the corresponding semi-conical shells 23 to rotate forward, and then pull the two sliders 1 20 along the corresponding slide rails 22 downward through the corresponding two connecting rods 2 19, thereby pushing the corresponding semi-conical shells 23 to rotate backward through the two connecting rods 1 18, and the conical shell group at the bottom opens, and the corresponding two tension springs 2 17 are stretched, as shown in FIG. Figure 8 As shown; then the garlic seeds with bulbils facing upwards fall from the seed storage space into a pre-dug pit (the pit can be pre-dug by manual labor or a digging mechanism); then as the central axis 4 rotates, the two push rods 16 located below disengage from the lower block 5, and due to the restoring force of the tension spring 2 17, the two semi-conical shells 23 located below move toward each other until they are closed, and push the slider 1 20 upward to its original position through the connecting rod 18 and the connecting rod 2 19.

4. A sowing method with a bud-forming and sowing mechanism according to any one of claims 1 to 3, characterized in that: The details are as follows: The external power drives the frame forward, and drives the central shaft to rotate the wheel discs 1 and 2, and then drives the wheel disc 3 to rotate through the connecting rods. During the movement, the connecting rods only move in translation relative to the ground, so that the cam rollers in the bud-correcting devices are always in translation when not correcting the buds. When the two push rods at the top of one of the bud-correcting devices without garlic seeds come into contact with the upper block, the upper block prevents the two push rods from continuing to rotate forward, thereby pushing the two push rods to rotate backward, and the two push rods drive the corresponding semi-conical shells to rotate backward, and then pull the two sliders one along the corresponding slide rails upward through the two connecting rods two, and the two sliders one push the corresponding semi-conical shells to rotate forward through the two connecting rods one, and the conical shell group at the top of the bud-correcting device opens, and the corresponding two tension springs two are stretched; then a garlic seed is put into the seed storage space of the bud-correcting device; then, as the central axis rotates, the two push rods at the top disengage from the upper block, and due to the restoring force of the tension spring two, the two semi-conical shells at the top move toward each other to close, and push the slider one downward to its original position through the corresponding connecting rod one and connecting rod two; The visual recognition device judges the state of the garlic seed bulbs in the seed storage space of the positive bud device containing the garlic seeds; if the visual recognition device detects that the garlic seed bulbs in the seed storage space are facing downward, the driving member drives the flip block to move backward a preset distance. As the central axis rotates, the push shaft in the positive bud device containing the garlic seeds and the bulbs facing downward contacts the flip block, and the flip block gives thrust to the push shaft, but due to the blocking effect of the corresponding one-way block, the push shaft cannot move in the direction of the horizontal groove one or horizontal groove two-way rotating device, and then the push shaft moves in the direction of the spiral groove one or spiral groove two-way rotating device, driving the cam roller to rotate relative to the rotating shaft, and the connecting plate integrally formed on the cam roller drives the rotating device to rotate, and the tension spring is stretched until the push shaft moves to the horizontal groove The cam roller drives the rotating device to rotate 180 degrees, and the garlic seeds in the seed storage space change from bulbils facing downward to bulbils facing upward; as the central axis rotates, the push shaft disengages from the flip block, due to the restoring force of the tension spring one, the tension spring one pulls the push shaft to move along the horizontal groove two or horizontal groove one toward the connecting frame, and the push shaft contacts the one-way block and pushes the one-way block to rotate upward until the push shaft disengages from the one-way block and moves to the end of the horizontal groove two or horizontal groove one close to the connecting frame; then, due to the restoring force of the torsion spring, the one-way block rotates downward to its original position, completing the bud correction work; if the visual recognition device detects that the garlic seed bulbs in the seed storage space are facing upward, the driving member does not work; As the central axis continues to rotate, when the garlic seeds are loaded and the garlic bulbs are facing upward or the two push rods at the bottom of the bud-forming device complete the bud-forming work and contact the lower block, the lower block pulls the two push rods to rotate forward, and the two push rods drive the corresponding semi-conical shells to rotate forward, and then pull the two sliders one along the corresponding slide rails through the corresponding two connecting rods two, thereby pushing the corresponding semi-conical shells to rotate backward through the two connecting rods one, and the conical shell group at the bottom opens, and the corresponding two tension springs two are stretched; then the garlic seeds with the bulbs facing upward fall from the seed storage space into the pre-dug pit; then as the central axis rotates, the two push rods at the bottom disengage from the lower block, and due to the restoring force of the tension spring two, the two semi-conical shells at the bottom move toward each other to close, and push the slider one upward to its original position through the connecting rod one and the connecting rod two.
