Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product sorting equipment, in particular to a sorting device for processing bamboo shoots. Background Art

[0002] In the processing of bamboo shoots, grade sorting based on the thickness (i.e., ground diameter) of the bamboo shoots is an important step. However, due to the specific shape of bamboo shoots and the fragility of the tips, conventional fruit and vegetable grading and screening equipment is difficult to achieve ideal sorting results. Although some technical improvements have been proposed, such as the bamboo shoot coarse and fine sorting mechanism disclosed in CN221694363U and the bamboo shoot sorting method disclosed in CN118892996A, these technical solutions have made significant progress in the bamboo shoot sorting effect, but none of them have proposed substantial improvement measures for the feeding mechanism. When the messy bamboo shoots enter the screening mechanism, they are difficult to effectively disperse by free rolling. The bamboo shoots that are gathered together will interact with each other and cannot be graded in an orderly manner. The sorting accuracy and efficiency need to be improved.

[0003] In addition, while bamboo shoots are primarily sorted by thickness (ground diameter), the weight of individual shoots is also important. Typically, bamboo shoots of the same grade are expected to weigh within a certain range and maintain a consistent appearance. However, due to issues like underdevelopment or breakage, some shoots fail to meet weight standards, and their appearance differs significantly from other shoots of the same grade. Existing grading and screening devices are unable to effectively remove these substandard shoots during the grading process, necessitating subsequent manual sorting, which undoubtedly reduces processing efficiency. Summary of the Invention

[0004] In order to address the shortcomings of the existing technology, the present invention provides a sorting device for bamboo shoot processing. By optimizing the structure, working principle and coordination mode of the feeding device, grading device and collecting device, the bamboo shoots can enter the grading device evenly and orderly, thereby improving the grading accuracy and efficiency. During the collection process, the graded bamboo shoots are weighed and screened one by one, and bamboo shoots that do not meet the weight standard are removed, saving the subsequent manual picking process, thereby improving processing efficiency.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0011] In a preferred embodiment, one end of the slide rod is transmission-connected to a motor device; the slide rod can reduce the resistance of the bamboo shoots as they move along the second conveyor belt by rotating, and in particular can prevent the bamboo shoots from getting stuck in the gap between the second conveyor belt and the slide rod.

[0012] In a preferred embodiment, the rear section of the first conveyor belt is provided with a horizontal conveying section, and the conveying section is provided with a stabilizing section on the rear side of the cloth section, and the stabilizing section is located on the upper side of the horizontal conveying section; baffles are provided on both sides of the stabilizing section; the bamboo shoots can move more smoothly in the stabilizing section and enter the grading device more stably.

[0013] In a preferred embodiment, a sliding plate is overlapped between the rear end of the first conveyor belt and the front end of the second conveyor belt, and the bamboo shoots output by the feeding device slide onto the second conveyor belt via the sliding plate.

[0014] In a preferred embodiment, the guide plate and the baffle are fixed to the partition in an adjustable manner; the slide bar is fixed to the grading device in an adjustable manner; thereby improving the applicability of the sorting device.

[0015] In a preferred embodiment, side panels are provided on both sides of the partition, and a return port is provided between the front end of the material guide plate and the side panel on the same side.

DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] This embodiment discloses a sorting device for processing bamboo shoots, which includes a feeding device, a grading device and a collecting device.

[0038] Among them, see Figure 1-Figure 5 As shown, the feeding device includes a hopper 1 and a first conveyor belt 2, the hopper 1 is used to store bamboo shoots to be sorted; the first conveyor belt 2 is placed obliquely, with the front lower and the back higher, and is used to convey the bamboo shoots in the hopper 1 backward; the upper side of the first conveyor belt 2 is covered with a partition 5, and a hollow conveying area is provided on the partition 5. Since the first conveyor belt 2 is covered by the partition 5 and is only exposed in the conveying area, the first conveyor belt 2 can only drive the bamboo shoots to move from front to back in the conveying area when it is running; the conveying area includes a feeding section 17 and a distribution section 18 distributed in front and back and connected; the The feeding section 17 is located in the hopper 1, and its width gradually decreases from front to back. Two guide plates 3 distributed in an eight-shape are fixed on both sides of the feeding section 17. When the bamboo shoots tend to be vertical, that is, when the length direction of the bamboo shoots tends to be consistent with the conveying direction, they can pass through the gap between the rear ends of the two guide plates 3 and enter the feeding section 18; the width of the feeding section 18 is further narrowed relative to the rear end of the feeding section 17, so that the width of the feeding section 18 is smaller than the width of the rear end of the feeding section 17. Preferably, the feeding section 18 can only accommodate one bamboo shoot in the width direction, and baffles 4 are provided on both sides of the feeding section 18 to limit the lower side of the bamboo shoots.

[0039] See Figure 3-Figure 5 As shown, when the first conveyor belt 2 is running, the bamboo shoots in the hopper 1 are guided by the two guide plates 3 and adjusted in direction by rolling. When the length direction of the bamboo shoots tends to be consistent with the conveying direction, they will pass through the two guide plates 3 and enter the cloth section 18. Since the width of the cloth section 18 is further narrowed, it can only accommodate one bamboo shoot in the width direction. The bamboo shoots stacked on the upper side of the other bamboo shoots will roll onto the partitions 5 on both sides of the cloth section 18, and slide downward along the inclined partitions 5 based on their own weight and fall back into the hopper 1; the bamboo shoots located in the cloth section 18 are further adjusted in direction under the limiting action of the baffle 4, tend to be vertical in the conveying area, are arranged one by one, and are transported backward in an orderly manner through the second conveyor belt 9.

[0040] Among them, see Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 As shown, the grading device includes a second conveyor belt 9 and a slide bar 10; one side of the second conveyor belt 9 is higher than the other side, and the second conveyor belt 9 can receive the bamboo shoots output one by one by the loading device; the slide bar 10 is located above the lower side of the second conveyor belt 9, and the distance between the two gradually increases from front to back.

[0041] After bamboo shoots discharged from the feeding device land on the second conveyor belt 9, they slide to the lower side due to their own weight until they come into contact with the slide bar 10. From then on, they are supported by the second conveyor belt 9 and the slide bar 10 and driven backward by the second conveyor belt 9. As the distance between the slide bar 10 and the second conveyor belt 9 increases, the bamboo shoots pass through the gap between the slide bar 10 and the second conveyor belt 9 and roll downward. In this way, as the bamboo shoots move from front to back along the second conveyor belt 9, they roll down at different positions at the front and back according to their thickness, completing the classification and screening.

[0042] Among them, see Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 As shown, there are multiple collecting devices, which are installed on the lower side of the second conveyor belt 9 and arranged in sequence along the conveying direction of the second conveyor belt 9; the collecting device includes a first material sliding plate 11 and a second material sliding plate 16 which are arranged obliquely; the upper end of the first material sliding plate 11 is located on the lower side of the lower side of the second conveyor belt 9, and the lower end is connected to the first collecting bucket 14, and a leakage port 12 is provided on the first material sliding plate 11; the second material sliding plate 16 is located below the leakage port 12, and the lower end of the second material sliding plate 16 is connected to the second collecting bucket 15; a weighing mechanism is provided on the lower side of the first material sliding plate 11, and the weighing mechanism includes a movable weighing plate 13, which is located in the leakage port 12 and blocks the leakage port 12 when in the reset state, and the weighing mechanism can control the switching state of the leakage port 12 according to the weight of the bamboo shoots fed back by the weighing plate 13.

[0043] See Figure 6 、 Figure 9 、 Figure 10 As shown, after the bamboo shoots screened by the grading device slide onto the corresponding first chute plate 11, they will slide downward along the first chute plate 11. When the bamboo shoots pass through the upper side of the weighing plate 13, if the weight meets the standard, the weighing plate 13 will move to open the leakage port 12. Thereafter, the bamboo shoots will roll through the leakage port 12 onto the second chute plate 16 and finally slide into the second collecting bucket 15. On the contrary, if the weight of the bamboo shoots does not meet the standard, the leakage port 12 will remain closed, and the bamboo shoots will continue to slide along the first chute plate 11 to the first collecting bucket 14, thereby removing the bamboo shoots that do not meet the weight standard.

[0044] The conveying speed of the second conveyor belt 9 is higher than that of the first conveyor belt 2, so as to ensure that the bamboo shoots maintain a sufficient distance on the second conveyor belt 9, and avoid the bamboo shoots from interfering with each other and affecting the grading effect. At the same time, since the conveying speeds of the first conveyor belt 2 and the second conveyor belt 9 can be adjusted, and the conveying speed of the second conveyor belt 9 is higher than that of the first conveyor belt 2, in actual processing operations, the conveying speeds of the first conveyor belt 2 and the second conveyor belt 9 are debugged and matched, so that the adjacent bamboo shoots that fall onto the second conveyor belt 9 one after another can maintain a sufficient distance, so as to avoid the situation where two or more bamboo shoots are simultaneously located on the same weighing plate 13, thereby ensuring that the weighing mechanism can perform weight screening on each bamboo shoot one by one, and ensure the accuracy of the screening.

[0045] When the bamboo shoot processing sorting device is in operation, the feeding device can arrange the bamboo shoots so that they enter the grading device at a uniform and orderly speed for grading. This avoids the impact of the chaotic distribution of bamboo shoots on grading accuracy and significantly improves grading accuracy. Using the collection device, bamboo shoots of the same grade can be screened one by one based on weight as an indicator, and those that do not meet the weight standard are removed. This saves the subsequent sorting process, facilitates subsequent automated processing, and ensures the specifications and quality of the product.

[0046] The structure of the sorting device for processing bamboo shoots is ingenious and reasonable. In the feeding device, the appearance characteristics and dead weight of the bamboo shoots are fully utilized. Only the first conveyor belt 2 provides the driving effect, which can realize the arrangement and transportation of the bamboo shoots and can realize the return of excess bamboo shoots. In the grading device, the bamboo shoots are supported by the slide bar 10 and the second conveyor belt 9 and conveyed by the second conveyor belt 9. Grading is achieved while being transported, and the grading efficiency is high. In the collecting device, weight screening is completed in the process of the bamboo shoots sliding downward, and no additional conveying components are required. Based on the ingenious design and reasonable coordination of the above components, the sorting efficiency, grading accuracy, and working energy consumption of the sorting device for processing bamboo shoots have been effectively improved, and the overall benefits have been significantly improved.

[0047] When the bamboo shoot processing sorting device is working, the bamboo shoots are moved in an orderly manner during the transportation and sorting process. In addition, the up and down movement process is mostly carried out along the inclined surface, which can reduce the mechanical damage to the bamboo shoots and significantly reduce the breakage of the bamboo shoot tips.

[0048] Preferably, Figure 7 As shown, one end of the slide rod 10 is in transmission connection with a motor device 21; thus, the slide rod 10 reduces the resistance of the bamboo shoots when they move along the second conveyor belt 9 by rotating, reduces the external force applied to the bamboo shoots during transportation, and especially prevents the bamboo shoots from being stuck in the gap between the second conveyor belt 9 and the slide rod 10.

[0049] Preferably, Figure 1 、 Figure 2 、 Figure 3 As shown, the rear section of the first conveyor belt 2 is provided with a horizontal conveying section. Correspondingly, the conveying section is provided with a stabilizing section 19 on the rear side of the material distribution section 18. The stabilizing section 19 is located on the upper side of the horizontal conveying section. Baffles 7 are provided on both sides of the stabilizing section 19 to prevent the bamboo shoots from slipping off. As a result, the bamboo shoots can move more smoothly and synchronously with the first conveyor belt 2 in the stabilizing section 19, can enter the grading device more stably, and ensure that the speed of each bamboo shoot when entering the grading device is consistent, thereby improving the feeding effect.

[0050] Preferably, Figure 1 、 Figure 2 As shown, a sliding plate 8 is overlapped between the rear end of the first conveyor belt 2 and the front end of the second conveyor belt 9 , and the bamboo shoots output by the feeding device slide onto the second conveyor belt 9 through the sliding plate 8 .

[0051] Preferably, the guide plate 3 and the baffle 4 are fixed to the partition 5 in an adjustable manner. Due to the large differences in the shapes of different bamboo shoots, the guide plate 3 and the baffle 4 are installed in an adjustable manner, which can be adjusted according to the actual processing conditions to improve the applicability of the feeding device. Similarly, the slide bar 10 is fixed to the grading device in an adjustable manner to improve the applicability of the grading device.

[0052] Preferably, Figure 1 、 Figure 3 As shown, side panels 6 are provided on both sides of the partition 5, and a return port 20 is provided between the front end of the guide plate 3 and the side panel 6 on the same side. As a result, when the bamboo shoots slide downward along the partition 5 for return, they will not fall from the sides of the partition 5 to the outside of the feeding device. In addition, by providing the return port 20, the return position of the bamboo shoots can be controlled to avoid interference between return and feeding.

[0053] In the present bamboo shoot processing and sorting device, the weighing mechanism can be implemented based on existing weight sensing and automatic control technologies, and there are multiple implementation options. For example, a weighing sensor and a driving device can be connected to the weighing plate 13. When the weight borne on the weighing plate 13 is higher than the set value, the driving device adjusts the position of the weighing plate 13 to open the leakage port 12. When the weight borne on the weighing plate 13 is not higher than the set value, the weighing plate 13 maintains the reset state. In addition, the present invention provides a more preferred implementation structure for the weighing mechanism:

[0054] See Figures 8-10As shown, one end of the weighing plate 13 is rotatably fixed to the lower side of the first material sliding plate 11 via a rotating shaft 22, and the end of the weighing plate 13 is fixedly connected to a weighing rod 23. The weighing plate 13 and the weighing rod 23 constitute a lever mechanism, and a counterweight 24 is installed on the weighing rod 23. Thus, the weighing plate 13, the weighing rod 23 and the counterweight 24 essentially constitute a weighing mechanism equivalent to a steelyard. Under the action of the weighing rod 23 and the counterweight 24, the weighing plate 13 is attached to the lower side of the material discharge port 12 and can bear a certain weight. The specific size of the weight can be adjusted by adjusting the counterweight The position or specification of the code 24 is adjusted to serve as a reference standard value for measuring whether the weight of the bamboo shoots meets the standard; thus, by utilizing the lever balance principle, when bamboo shoots that do not meet the weight standard move from the upper side of the weighing plate 13, the weighing plate 13 cannot be driven to rotate, and the bamboo shoots will continue to move downward and enter the first collecting bucket 14; conversely, when bamboo shoots that meet the weight standard move from the upper side of the weighing plate 13, the weighing plate 13 will be driven to rotate downward, the material leakage port 12 will be opened, and the bamboo shoots will fall through the material leakage port 12 onto the second material chute 16, and finally move to the second collecting bucket 15, thereby achieving weight screening of the bamboo shoots. When the weighing mechanism adopts the above design, there is no need to set up additional power devices and sensor elements, the implementation cost is low, maintenance is easy, and the energy consumption of the equipment can be significantly reduced.

[0055] Furthermore, the weighing rod 23 is provided with a thread, and the counterweight 24 is sleeved on the weighing rod 23 and the two are threadedly matched. By rotating the counterweight 24, its position can be adjusted, thereby conveniently adjusting the reference standard value during weight screening;

[0056] Further, such as Figure 9 、 Figure 10 As shown, the higher end of the weighing plate 13 is rotatably connected to the first sliding plate 11. When the weighing plate 13 flips downward, the weighing plate 13 overlaps the second sliding plate 16 in an inclined state. Therefore, when the bamboo shoots fall into the second sliding plate 16 through the leakage hole, they can slide downward along the inclined weighing plate 13, thereby avoiding mechanical damage to the bamboo shoots caused by falling.
