Description

Technical Field

[0001] The present invention relates to the technical field of taro seedling planting, and specifically relates to a taro seedling separating device. Background Art

[0002] Automated taro seedling planting is generally completed by the cooperation of a seedling storage bin, a seedling separating conveyor belt, a pushing device, and a transplanting device. Among them, the taro seedlings fall from the outlet below the seedling storage bin into the grooves formed by adjacent baffles on the seedling separating conveyor belt to complete the seedling separating work. After the taro seedling pushing device arranged at the end of the seedling separating conveyor belt senses the taro seedling in the groove, it pushes the taro seedling in the groove towards the transplanting device through a telescopic action, and the transplanting device clamps the taro seedling and plants it into the soil.

[0003] Since taro seedlings are not regular cylinders and there is a small degree of bending, the width of the groove is usually larger than the diameter of the taro seedling to facilitate the normal entry of the taro seedling into the groove. However, it is easy to have a situation where two taro seedlings are in one groove. Since the surface of the taro seedling is not smooth, when two taro seedlings enter one groove at the same time, the upper taro seedling will protrude from the groove. At this time, the upper and lower sides of the taro seedling will be blocked by the baffle on the seedling storage bin and the seedling separating conveyor belt respectively. As the seedling separating conveyor belt moves, the taro seedling will be sheared and squeezed, resulting in damage to the taro seedling. Summary of the Invention

[0004] The present invention specifically provides a taro seedling separating device, which includes a feeding mechanism, a guiding plate, and a seedling separating conveyor belt arranged in sequence according to the moving order of the taro seedlings; The feeding mechanism is used to individually feed taro seedlings onto the guiding plate. The head and tail ends of the guiding plate are respectively close to the discharge port of the feeding mechanism and the starting end of the seedling separating conveyor belt, and the guiding plate is inclined to conduct the taro seedlings fed by the feeding mechanism from high to low onto the seedling separating conveyor belt; The included angle between the transmission direction of the seedling separating conveyor belt and the inclination direction of the guiding plate is an acute angle to prevent the taro seedlings from jamming between the seedling separating conveyor belt and the guiding plate.

[0005] As a preferred solution of the present invention, the feeding mechanism includes a seedling storage bin and a guiding conveyor belt. The seedling storage bin is arranged above the starting end of the guiding conveyor belt. The guiding conveyor belt is used to individually convey the taro seedlings in the seedling storage bin to the guiding plate. The head and tail ends of the guiding plate are respectively close to the guiding conveyor belt and the seedling separating conveyor belt; A flipping baffle and a waste material plate are sequentially installed at the outlet end of the guiding plate, wherein the flipping baffle is rotatably connected to the guiding plate, and the waste material plate is fixedly connected to the guiding plate; The flipping baffle can be flipped upwards to block the outlet of the guiding plate, or flipped downwards to be parallel to the guiding plate to feed the taro seedlings onto the seedling separating conveyor belt; One side at the junction of the material guiding plate and the material guiding conveyor belt is equipped with a counting optoelectronic device; When the flipping baffle blocks the outlet of the material guiding plate, the material guiding conveyor belt operates so that the taro seedlings are put and temporarily stored on the material guiding plate; When the number of taro seedlings on the material guiding plate reaches a predetermined number, the material guiding conveyor belt stops operating, and the flipping baffle flips downward to be parallel to the material guiding plate, so as to put the temporarily stored taro seedlings one by one onto the seedling separating conveyor belt; The surplus material plate is used to cache the taro seedlings that have left the material guiding plate but have not yet reached the seedling separating conveyor belt, so that when the flipping baffle flips upward to temporarily store the taro seedlings, there can still be taro seedlings continuing to be put onto the seedling separating conveyor belt.

[0006] As a preferred solution of the present invention, the partition plates on the seedling separating conveyor belt are inclined, and the inclined direction is opposite to the conveying direction of the seedling separating conveyor belt. Grooves for temporarily storing taro seedlings are formed between adjacent two partition plates; A rolling brush perpendicular to the taro seedling conveying direction is arranged on the seedling separating conveyor belt. When the rolling brush rotates, it can brush the second taro seedling falling into the groove to the next groove, so that at most one taro seedling exists in each groove; A protective shell covering the rolling brush is also arranged on the seedling separating conveyor belt, which can prevent the taro seedlings from falling off the seedling separating conveyor belt.

[0007] As a preferred solution of the present invention, the distance between the lower end outlet of the seedling storage bin and the material guiding conveyor belt is between 1.1 and 1.3 times the diameter of the taro seedling.

[0008] As a preferred solution of the present invention, the feeding mechanism includes a seedling storage bin, and the distance between the lower end outlet of the seedling storage bin and the material guiding plate is 1.2 - 1.4 times the diameter of the taro seedling; On the extended guard plates on both sides of the outlet end of the material guiding plate, a flipping baffle and a flipping feeding plate are sequentially rotatably connected. The width of the flipping feeding plate is 1.2 - 1.3 times the diameter of the taro seedling, and the discharging end of the flipping feeding plate is bent upward to form a material blocking slope; The flipping baffle and the flipping feeding plate have two working states: The whole flipping feeding plate flips upward to be horizontal, and the flipping baffle flips downward to be flush with the material guiding plate. At this time, one taro seedling is accommodated on the flipping feeding plate; The flipping baffle flips upward to block the material guiding plate, and the flipping feeding plate flips downward to put the taro seedling it accommodates onto the seedling separating conveyor belt.

[0009] As a preferred solution of the present invention, the slope of the material guiding plate is 25° - 35°, so as to prevent the taro seedlings on the material guiding plate from squeezing out the taro seedlings on the flipping feeding plate in the horizontal state.

[0010] As a preferred embodiment of the present invention, the width of the material guiding plate is 1.1 - 1.2 times the length of the taro seedlings, and guard plates are arranged on both sides of the material guiding plate to prevent the taro seedlings from detaching from the side of the material guiding plate.

[0011] As a preferred embodiment of the present invention, the seedling storage bin includes a bin box in the upper part and a seedling emergence channel in the lower part. The width of the seedling emergence channel gradually decreases from top to bottom, and the width at the outlet is 1.2 - 1.3 times the diameter of the taro seedlings.

[0012] As a preferred embodiment of the present invention, both the flipping baffle and the flipping feeding plate are driven to rotate by air cylinders.

[0013] The present invention has the following beneficial effects compared with the prior art: A material guiding plate is added between the feeding mechanism and the seedling separating conveyor belt. The taro seedlings discharged from the feeding mechanism are conveyed to the seedling separating conveyor belt by the inclined material guiding plate. Since the included angle between the inclined direction of the material guiding plate and the conveying direction of the seedling separating conveyor belt is an acute angle, the taro seedlings will be conveyed away from the material guiding plate after falling on the seedling separating conveyor belt. There is no obstruction above the advancing direction of the seedling separating conveyor belt, so shearing cannot be formed. Even if there are two taro seedlings in the same groove, the situation where the upper and lower sides of the taro seedlings are simultaneously blocked, resulting in damage to the taro seedlings due to shearing and extrusion, will not occur.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] The present invention specifically provides a taro seedling separation device, including a feeding mechanism, a feeding guide plate 4, and a seedling separation conveyor belt 5 sequentially arranged according to the moving order of the taro seedlings 1. The feeding mechanism is used to individually feed the taro seedlings 1 onto the feeding guide plate 4. The head and tail ends of the feeding guide plate 4 are respectively close to the discharge port of the feeding mechanism and the starting end of the seedling separation conveyor belt 5, and the feeding guide plate 4 is inclined to conduct the taro seedlings 1 fed by the feeding mechanism from high to low onto the seedling separation conveyor belt 5. The included angle between the transmission direction of the seedling separation conveyor belt 5 and the inclination direction of the feeding guide plate 4 is an acute angle to prevent the taro seedlings 1 from jamming between the seedling separation conveyor belt 5 and the feeding guide plate 4.

[0019] In the present invention, a feeding guide plate 4 is added between the feeding mechanism and the seedling separation conveyor belt 5. The inclined feeding guide plate 4 transmits the taro seedlings 1 discharged from the feeding mechanism onto the seedling separation conveyor belt 5. Since the included angle between the inclination direction of the feeding guide plate 4 and the transmission direction of the seedling separation conveyor belt 5 is an acute angle, the taro seedlings 1 will be transmitted away from the feeding guide plate 4 after falling on the seedling separation conveyor belt 5. There is no obstruction above the advancing direction of the seedling separation conveyor belt 5, and no shearing can be formed. Even if there are two taro seedlings 1 in the same groove 10, the situation where the upper and lower sides of the taro seedlings 1 are simultaneously blocked, resulting in damage to the taro seedlings 1 due to shearing and extrusion, will not occur.

[0020] Furthermore, although the above-mentioned seedling separation device can avoid damage to the taro seedlings 1, the situation where there are two taro seedlings 1 in one groove 10 still cannot be avoided. To further solve this problem and enable each taro seedling 1 to be effectively planted, the present invention provides the following two solutions: Embodiment 1 The feeding mechanism includes a seedling storage bin 2 and a feeding conveyor belt 3. The seedling storage bin 2 is arranged above the starting end of the feeding conveyor belt 3. The feeding conveyor belt 3 is used to convey the taro seedlings 1 in the seedling storage bin 2 to the guiding plate 4 one by one. The two ends of the guiding plate 4 are respectively close to the feeding conveyor belt 3 and the seedling separating conveyor belt 5. The guiding plate 4 is inclined to conduct the taro seedlings 1 fed by the feeding mechanism from high to low onto the seedling separating conveyor belt 5. A flipping baffle 6 and a surplus material plate 7 are successively installed at the outlet end of the guiding plate 4. Among them, the flipping baffle 6 is rotatably connected to the guiding plate 4, and the surplus material plate 7 is fixedly connected to the guiding plate 4. The flipping baffle 6 can flip upward to block the outlet of the guiding plate 4, or flip downward to be parallel to the guiding plate 4 to feed the taro seedlings 1 onto the seedling separating conveyor belt 5. A counting photoelectric device is installed on one side of the junction of the guiding plate 4 and the feeding conveyor belt 3. It can be understood that other existing counting devices can also be used. For example, an image recognition device can be set above the junction to recognize and record the number of taro seedlings 1 transmitted to the guiding plate 4.

[0021] When the flipping baffle 6 blocks the outlet of the guiding plate 4, the feeding conveyor belt 3 operates so that the taro seedlings 1 are fed and temporarily stored on the guiding plate 4. When the number of taro seedlings 1 on the guiding plate 4 reaches a predetermined number, the feeding conveyor belt 3 stops operating, and the flipping baffle 6 flips downward to be parallel to the guiding plate 4 to feed the temporarily stored taro seedlings 1 onto the seedling separating conveyor belt 5 one by one. The surplus material plate 7 is used to cache the taro seedlings 1 that have left the guiding plate 4 but have not yet reached the seedling separating conveyor belt 5, so that when the flipping baffle 6 flips upward to temporarily store the taro seedlings 1, there are still taro seedlings 1 continuing to be fed onto the seedling separating conveyor belt 5.

[0022] The specific working process is as follows: Initially, the flipping baffle 6 flips upward by a certain angle to block the outlet of the guiding plate 4 and prevent the taro seedlings 1 from sliding out. Taking the example that 10 taro seedlings 1 are temporarily stored on the guiding plate 4, when the counting photoelectric device installed recognizes the 10th taro seedling 1, the feeding conveyor belt 3 stops operating and no longer conveys the taro seedlings 1 to the guiding plate 4. The taro seedlings 1 at the outlet of the seedling storage bin 2 block the seedling storage bin 2 and no longer feed the taro seedlings 1 onto the feeding conveyor belt 3.

[0023] Then, the flipping baffle 6 flips downward to open, and the 10 taro seedlings 1 temporarily stored on the guiding plate 4 fall into the grooves 10 of the seedling separating conveyor belt 5 through the surplus material plate 7. In the specific implementation process, it is necessary to coordinate the operating speed of the seedling separating conveyor belt 5 and the inclination angle of the guiding plate 4 so that the taro seedlings 1 evenly fall into each groove 10.

[0024] When all 10 taro seedlings 1 have passed over the flipping baffle 6, the flipping baffle 6 immediately flips upward, and the feeding conveyor belt 3 immediately starts, so that the taro seedlings 1 are quickly conveyed to the guiding plate 4.

[0025] When all 10 taro seedlings 1 have passed over the flipping baffle 6, not all of the taro seedlings 1 fall onto the seedling-sorting conveyor belt 5. There are still some taro seedlings 1 on the residue plate 7 to ensure that before the flipping baffle 6 flips downward next time, there are continuously taro seedlings 1 being placed onto the continuously running seedling-sorting conveyor belt 5. On the one hand, it improves the seedling-sorting efficiency, and on the other hand, it avoids the situation where the number of taro seedlings 1 placed is less than the number of grooves 10. The length of the residue plate 7 and the running speed of the guiding conveyor belt 3 are determined according to the actual situation, so that the number of taro seedlings 1 placed onto the seedling-sorting conveyor belt 5 is equal to the number of grooves 10 passing through the outlet of the residue plate 7 in the same time.

[0026] It should be noted that since the flipping baffle 6 is a flat plate, when the taro seedlings 1 slide along the guiding plate 4 to the flipping baffle 6, they will be aligned one by one with the flipping baffle 6 as a reference under the action of gravity, calibrating the taro seedlings 1, which can lay a foundation for the subsequent accurate falling of the taro seedlings 1 into the grooves 10 on the seedling-sorting conveyor belt 5.

[0027] In practice, it is difficult to make the number of taro seedlings 1 placed onto the seedling-sorting conveyor belt 5 equal to the number of grooves 10 passing through the outlet of the residue plate 7 in the same time, and for each taro seedling 1 to fall into one groove 10. It is necessary to comprehensively consider the slope of the guiding plate 4, the running speeds of the guiding conveyor belt 3 and the seedling-sorting conveyor belt 5, as well as the lengths of the guiding plate 4 and the residue plate 7, etc.

[0028] Therefore, based on the above-mentioned Embodiment 1, the present invention further provides a more preferred implementation manner, that is, it only requires that the number of taro seedlings 1 placed onto the seedling-sorting conveyor belt 5 is equal to the number of grooves 10 passing through the outlet of the residue plate 7 in the same time, allowing multiple taro seedlings 1 to accumulate successively on the residue plate 7, and in the case of two taro seedlings 1 entering one groove 10 under the action of gravity, specifically as follows: The partition plates 9 on the seedling-sorting conveyor belt 5 are inclined, and the inclined direction is opposite to the transmission direction of the seedling-sorting conveyor belt 5. Grooves 10 for temporarily storing taro seedlings 1 are formed between adjacent two partition plates 9; a rotary brush 11 perpendicular to the transmission direction of the taro seedlings 1 is arranged on the seedling-sorting conveyor belt 5. When the rotary brush 11 rotates, it can brush the second taro seedling 1 falling into the groove 10 to the next groove 10, so that at most one taro seedling 1 exists in each groove 10; a protective shell 12 covering the rotary brush 11 is also arranged on the seedling-sorting conveyor belt 5, which can prevent the taro seedlings 1 from falling off the seedling-sorting conveyor belt 5.

[0029] If there are two taro seedlings 1 in the groove 10, when the rotary brush 11 rotates, the bristles on the rotary brush 11 can brush out the taro seedling 1 with only a small part of the seedling body located in the groove 10 above the groove 10, and with the operation of the seedling separating conveyor belt 5, the taro seedling 1 enters the empty groove 10 in the oncoming flow. That is, through the cooperation of the rotary brush 11 and the protective shell 12, as long as the number of taro seedlings 1 placed on the seedling separating conveyor belt 5 is equal to the number of grooves 10 passing through the outlet of the surplus material plate 7 in the same time, even if there are two taro seedlings 1 in some grooves 10 and no taro seedlings 1 in some grooves 10, with the rotation of the rotary brush 11 and the continuous operation of the seedling separating conveyor belt 5, the second taro seedling 1 in the groove 10 can enter the empty groove 10, so that each groove 10 has only one taro seedling 1.

[0030] Furthermore, due to the small amplitude of complete seedlings, in order to enable the taro seedlings 1 to be smoothly removed from the lower outlet of the seedling storage bin 2, the distance between the lower outlet of the seedling storage bin 2 and the material guiding conveyor belt 3 is between 1.1 and 1.3 times the diameter of the taro seedling 1. Even if a small part of the second taro seedling 1 above the taro seedling 1 falling out of the outlet of the seedling storage bin 2 is exposed from the seedling storage bin 2, since only the upper part of the second taro seedling 1 is blocked by the seedling storage bin 2, the situation of seedling jamming resulting in damage to the taro seedling 1 will not occur.

[0031] Embodiment 2 The feeding mechanism includes a seedling storage bin 2, and the distance between the lower outlet of the seedling storage bin 2 and the material guiding plate 4 is 1.2 - 1.4 times the diameter of the taro seedling 1 to ensure that the taro seedling 1 can slide or roll down along the material guiding plate 4 normally; The outlet end of the material guiding plate 4 is sequentially rotatably connected with a flipping baffle 6 and a flipping feeding plate 14. The flipping baffle 6 and the flipping feeding plate 14 are independent of each other, and both the flipping baffle 6 and the flipping feeding plate 14 can be rotatably connected to the guard plate 13 on the side of the material guiding plate 4 through a rotating shaft; the width of the flipping feeding plate 14 is 1.2 - 1.3 times the diameter of the taro seedling 1, and it can only accommodate one taro seedling 1, and the discharging end of the flipping feeding plate 14 is bent upward to form a material blocking slope 15; The flipping baffle 6 and the flipping feeding plate 14 have two working states: Storage state: The flipping feeding plate 14 is turned upward as a whole to be horizontal, and the flipping baffle 6 is turned downward to be flush with the material guiding plate 4. At this time, the taro seedling 1 on the material guiding plate 4 will roll towards the flipping feeding plate 14 under the action of gravity. Due to the existence of the material blocking slope 15, the taro seedling 1 rolling onto the flipping feeding plate 14 will not directly roll out of the flipping feeding plate 14 due to the extrusion of the subsequent taro seedlings 1 on the material guiding plate 4. At this time, the flipping feeding plate 14 stably accommodates one taro seedling 1; Feeding state: After feeding one taro shoot 1 onto the flipping feeding plate 14, the flipping baffle 6 flips upward to block the guiding plate 4, and the flipping feeding plate 14 flips downward to drop the taro shoot 1 it holds onto the seedling separation conveyor belt 5. The flipping angle of the flipping feeding plate 14 and the inclination angle of the material blocking slope 15 can be adjusted according to the actual situation. When the flipping feeding plate 14 is horizontal, it can prevent the taro shoot 1 from rolling out directly, and when the flipping feeding plate 14 flips downward, it can enable the seedling to roll out.

[0032] After the feeding is completed, the flipping feeding plate 14 first flips upward to the horizontal position, and then the flipping baffle 6 flips downward to be flush with the guiding plate 4; when starting to feed, the flipping baffle 6 first flips upward to block the guiding plate 4, and then the flipping feeding plate 14 flips downward.

[0033] Furthermore, the slope of the guiding plate 4 is 25° - 35°, to prevent the taro shoot 1 on the guiding plate 4 from squeezing out the taro shoot 1 on the flipping feeding plate 14 in the horizontal state.

[0034] Furthermore, the width of the guiding plate 4 is 1.1 - 1.2 times the length of the taro shoot 1, and both sides of the guiding plate 4 are provided with guard plates 13 to prevent the taro shoot 1 from detaching from the side of the guiding plate 4.

[0035] Furthermore, the seedling storage bin 2 includes an upper bin box 16 and a lower seedling outlet channel 17. The width of the seedling outlet channel 17 gradually decreases from top to bottom, and the width at the outlet is 1.2 - 1.3 times the diameter of the taro shoot 1, so that the taro shoots 1 drop from the outlet of the seedling storage bin 2 one by one.

[0036] Furthermore, both the flipping baffle 6 and the flipping feeding plate 14 are driven to rotate by cylinders 18. Specifically, the rotating shafts of the flipping baffle 6 and the flipping feeding plate 14 respectively pass through the guard plate 13 on one side of the guiding plate 4. One end of the rotating shaft penetrating the guard plate 13 is fixedly connected with a connecting rod 19, and the end of the connecting rod 19 far from the rotating shaft is rotatably connected with the end of the cylinder 18, and the other end of the cylinder 18 is rotatably installed on the outer side of the guard plate 13. By the telescopic movement of the cylinder 18, the flipping baffle 6 and the flipping feeding plate 14 can be flipped forward and backward.

[0037] It can be understood that other methods can also be used to drive the flipping baffle 6 and the flipping feeding plate 14 to rotate and flip, such as directly driving by a motor, and realizing the forward or reverse flipping of the flipping baffle 6 and the flipping feeding plate 14 through the forward and reverse rotation of the motor.

[0038] Furthermore, a telescopic pushing device is provided at the tail end of the seedling separation conveyor belt 5. Through the telescopic action, the taro shoot currently in the groove at the tail end of the seedling separation conveyor belt 5 can be pushed out of the groove by about 10 cm, and then pressed into the soil by the rotating wheel of the transplanting device. The telescopic pushing device can be a cylinder telescopic mechanism, a gear and rack telescopic mechanism, etc., which can perform linear reciprocating telescopic motion.

[0039] Photoelectric sensors are respectively arranged on both sides of the tail end of the seedling separation conveyor belt 5, one for detecting the taro seedlings 1 and the other for detecting the partition plate 9. Only when the photoelectric sensor detects the taro seedlings 1 and does not detect the partition plate 9, the telescopic pushing device will extend to push the taro seedlings. When the telescopic pushing device extends, the seedling separation conveyor belt 5 pauses running.

[0040] It should be noted that in the present invention, the seedling storage bin 2, the feeding conveyor belt 3, the feeding plate 4, the waste plate 7, the seedling separation conveyor belt 5 and the protective shell 12 are all directly or indirectly installed on the frame, and the frame and the transmission rollers at both ends of the conveyor belt are not shown in the drawings.

[0041] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
