Abstract
Description
Technical Field
[0001] This application relates to the field of Sichuan pepper conveying technology, specifically to a Sichuan pepper storage and conveying equipment and method. Background Technology
[0002] Sichuan pepper, also known as bamboo leaf pepper, is a plant belonging to the genus Zanthoxylum in the Rutaceae family. Its fruits are smaller than those of red Sichuan pepper, usually greenish-blue or emerald green, and have longer stalks. The fruits often grow in clusters, hence the name "Sichuan pepper". It is commonly used as a raw material for processing seasoning oil, and is combined with oil extraction technology to make seasoning oil with Sichuan pepper flavor.
[0003] When fresh Sichuan peppercorns are stored in cold storage after harvesting, they continue to respire, consuming their own sugars and nutrients and releasing heat in the process. This heat is difficult to dissipate inside the pile, leading to heat accumulation and a rise in internal temperature. Higher temperatures can cause the aroma of the Sichuan peppercorns to be lost, degrade the numbing substances, and even cause browning and mold growth, rendering the entire batch of Sichuan peppercorns inedible.
[0004] The conventional method of transporting Sichuan peppercorns into cold storage involves directly opening the cold storage and pouring the peppercorns in. This method can easily cause the peppercorns to accumulate heat and spoil. Secondly, this method can lead to uneven distribution of the peppercorns in the cold storage, resulting in low utilization of the cold storage. At the same time, this method requires the cold storage to be kept open for a long time, resulting in high energy consumption. Summary of the Invention
[0005] To address the aforementioned deficiencies in existing technologies, this application provides a method and equipment for conveying Sichuan peppercorns into cold storage, which can prevent the peppercorns from spoiling, improve the utilization rate of cold storage, and save energy, thus possessing strong practicality.
[0006] To achieve the above objectives, the present invention employs the following techniques:
[0007] A conveying device for storing Sichuan peppercorns, used in conjunction with a mesh pipe and a limiting frame for storing Sichuan peppercorns, includes:
[0008] The loading compartment is open at both the top and bottom. Inside, there is a long installation channel that runs through both ends along its length and has an arched top. The lower end of the installation channel connects to the lower end of the loading compartment. The lower part of the loading compartment located outside the installation channel on both sides is rotatably fitted with rotating plates to control the opening and closing of the lower end of the loading compartment. The loading compartment is connected to a drive frame for connecting with external vehicles.
[0009] Multiple compression plates are installed inside the loading chamber. The surface of each plate is perpendicular to the length direction and is movable along the length direction. The compression plates are in sliding contact with the inner walls of both sides of the loading chamber, the outer walls of both sides of the installation channel, and the outer wall of the arched top.
[0010] The first adsorption mechanism is located in the middle of the installation channel and is used to adsorb the mating ring extending inward from the upper end of the mesh tube.
[0011] The second adsorption mechanism consists of two sets, located at both ends of the installation channel, and is used to adsorb the mating ears extending inward from the upper two sides of the limiting frame.
[0012] The beneficial effects of this invention are as follows:
[0013] By inserting mesh pipes during the storage of Sichuan peppercorns, the heat dissipation effect inside the peppercorn pile is improved, preventing heat accumulation and spoilage. Feeding the peppercorns into the limiting frame ensures even distribution within the cold storage, increasing its utilization rate. A loading bin is used to transport the peppercorns, and a compression plate is installed to increase the bin's single-load capacity. Each loading bin can carry a large amount of peppercorns into the cold storage, reducing the cold storage's opening time and saving energy. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.
[0024] like Figure 1 and Figure 2 As shown, in one aspect of this embodiment, a Sichuan pepper storage and conveying device is provided for storing Sichuan pepper in cooperation with a mesh pipe 6 and a limiting frame 7. The mesh pipe 6 is a pipe with a mesh structure, and the limiting frame 7 is a rectangular frame with open upper and lower ends. The mesh pipe 6 and the limiting frame 7 have the same height. The device includes a loading bin 1, a compression plate 2, a first adsorption mechanism 3, and a second adsorption mechanism 4.
[0025] Specifically, such as Figure 1 and Figure 2 As shown, the loading compartment 1 is a rectangular compartment with open top and bottom. A mounting channel 11 is formed in the middle of the lower end of the compartment, with its length parallel to the length of the loading compartment 1. The front and rear ends of the mounting channel 11 are connected to the outer sides of the front and rear ends of the loading compartment 1, respectively. The lower end is connected to the lower end of the loading compartment 1, and the upper end is an arched dome protruding from the upper end of the loading compartment 1. Rotating plates 12 are rotatably fitted to the lower end of the loading compartment 1 on both sides of the mounting channel 11. The rotating plates 12 are used to control the opening and closing of the lower end of the loading compartment 1. A drive frame 13 is connected to the outer side of the loading compartment 1, and the drive frame 13 is used to connect with the external vehicle.
[0026] Specifically, such as Figure 2As shown, there are multiple compression plates 2 evenly arranged in the loading chamber 1. In this example, there are a total of two compression plates 2. The plate surfaces are all perpendicular to the length direction and are movable along the length direction. The compression plates 2 are in sliding contact with the inner sides of the left and right sides of the loading chamber 1, the outer sides of the left and right sides of the mounting track 11, and the outer side of the upper end. The compression plates 2 are used to drive the rattan pepper in the loading chamber 1 to move and compress the rattan pepper.
[0027] Specifically, such as Figure 1 As shown, the first adsorption mechanism 3 is located in the middle of the installation channel 11 and is used to adsorb the mating ring 61 extending inward from the upper end of the mesh tube 6.
[0028] Specifically, such as Figure 1 As shown, the second adsorption mechanism 4 has two sets, which are respectively located at both ends of the mounting channel 11, and are used to adsorb the mating ears 71 extending inward from the upper two sides of the limiting frame 7.
[0029] During operation, the loading bin 1 is first moved to the outside of the cold storage using a crane. The rotating plate 12 is then used to close the lower end of the loading bin 1, and all compression plates 2 are moved so that they are all positioned at the front end of the loading bin 1. Sichuan peppercorns are then added to the loading bin 1 from the top. Because Sichuan peppercorns have many branches, there are still many gaps between the peppercorns. At this point, the first compression plate 2 closest to the peppercorns can be moved towards the rear end of the loading bin 1, allowing it to work in conjunction with the rear end of the loading bin 1 to compress the branches of the peppercorns, thus reducing the size of the peppercorns without damaging them. The spacing between the pepper pieces; after the first compression plate 2 has finished compressing, peppers can be put into the two compression plates 2 inside the loading chamber 1 from the top, and the second compression plate 2 can be moved towards the first compression plate 2 to compress the peppers that have entered the chamber for the second time; finally, peppers can be put into the space between the second compression plate 2 and the front face of the loading chamber 1; this design can greatly increase the amount of peppers that the loading chamber 1 can hold. Since the cold storage needs to be opened when the loading chamber 1 enters the cold storage, this design can significantly reduce the frequency and time of opening the cold storage, thus saving energy.
[0030] After loading the Sichuan peppercorns, move the loading bin 1 and use the first suction mechanism 3 to suction a mesh tube 6 and a limiting frame 7 at a suitable location. The mesh tube 6 and the limiting frame 7 can be placed either outside or inside the cold storage. Then, move the loading bin 1 to the designated location inside the cold storage. First, move the lower ends of the mesh tube 6 and the limiting frame 7 until they are in contact with the ground. Then, control the rotating plate 12 to open the lower end of the loading bin 1. At this time, the uncompressed Sichuan peppercorns between the second compression plate 2 and the front end of the loading bin 1 will pass through the lower end of the loading bin 1 into the area between the limiting frame 7 and the outer wall of the mesh tube 6. Move the second compression plate 2 to the front end of the loading bin 1. At this time, the Sichuan peppercorns between the second compression plate 2 and the first compression plate 2 will no longer be compressed and will also pass through the lower end of the loading bin 1 into the area between the limiting frame 7 and the outer wall of the mesh tube 6. The area between the walls; finally, the first compression plate 2 is moved to the front end of the loading chamber 1, and the remaining Sichuan pepper will also enter the area between the limiting frame 7 and the outer wall of the mesh tube 6 through the lower end of the loading chamber 1; the installation long channel 11 here can prevent the Sichuan pepper from falling into the mesh tube 6, and the upper end of the installation long channel 11 is set as an arch to prevent the Sichuan pepper from staying in the loading chamber 1. At the same time, the reciprocating movement of the compression plate 2 can push the Sichuan pepper into the limiting frame 7 more smoothly; with this design, the Sichuan pepper is restricted by the limiting frame 7, which can occupy less horizontal space and more vertical space in the cold storage, ensuring the uniform distribution of Sichuan pepper in the cold storage and improving the utilization rate of the cold storage; at the same time, the mesh tube 6 is set to ventilate and dissipate heat to the bottom Sichuan pepper, which improves the heat dissipation effect inside the Sichuan pepper pile and avoids heat accumulation that causes the Sichuan pepper to spoil.
[0031] Preferred, such as Figure 3 As shown, rotating columns 14 are provided at the lower ends of the inner sides of the left and right sides of the loading chamber 1, with their axes parallel to the length direction of the loading chamber 1. The two ends of the rotating columns 14 are rotatably connected to the inner sides of the front and rear ends of the loading chamber 1, respectively. The cylindrical surface of the rotating columns 14 is connected to the rotating plates 12. When the rotating columns 14 rotate to the point where the plate surface of the rotating plates 12 is perpendicular to the height direction of the loading chamber 1, the two ends of the rotating plates 12 contact the lower ends of the inner sides of the front and rear ends of the loading chamber 1, respectively. The sides of the two rotating plates 12 facing away from the rotating columns 14 contact the lower ends of the outer sides of the left and right sides of the mounting track 11, respectively. With this design, the rotating columns 14 are used to drive the rotating plates 12 to rotate, thereby controlling the opening and closing of the lower end 1 of the loading chamber 1.
[0032] Preferred, such as Figure 3 As shown, two first rotating motors 15 are provided on the outer side of the loading compartment 1. The drive shafts of the first rotating motors 15 are coaxially connected to the rotating column 14, and the first rotating motors 15 are used to drive the rotating column 14 to rotate.
[0033] Preferred, such as Figure 3As shown, there are n compression plates 2 inside the loading chamber 1. At the upper end of one inner side of the left or right side of the loading chamber 1, there are n electric lead screws 21 with driving directions parallel to the length direction. At the upper end of the other inner side of the left or right side of the loading chamber 1, there are n sliding rods 22 with axial directions parallel to the length direction. The electric lead screws 21 and sliding rods 22 are arranged in an array along the height direction of the loading chamber 1. The drive shafts of the electric lead screws 21 are threaded with mating blocks 23, and sliding blocks 24 are slidably sleeved on the sliding rods 22. The compression plates are compressed along the length direction from the front end to the rear end of the loading chamber 1. 2. Sort the electric lead screws 21 and slide rods 22 along the height direction from the top to the bottom of the loading bin 1. The upper end of the m-th compression plate 2 is connected to the mating block 23 on the m-th electric lead screw 21 and the slider 24 on the m-th slide rod 22, where 1≤m≤n; when n>1, nr through holes 25 are provided on both sides of the r-th compression plate 2 along the length direction, where 1≤r<n; the s-th electric lead screw 21 and the s-th slide rod 22 pass through the through holes 25 on the 1~s-1 compression plates 2, where 1<s≤n.
[0034] In this example, there are two compression plates 2 in the loading chamber 1, and two electric lead screws 21 and two slide bars 22. The upper end of the first compression plate 2 is connected to the mating block 23 on the first electric lead screw 21 and the slider 24 on the first slide bar 22. The upper end of the second compression plate 2 is connected to the mating block 23 on the second electric lead screw 21 and the slider 24 on the second slide bar 22. At the same time, there is a through hole 25 on both sides of the first compression plate 2. The second electric lead screw 21 and the second slide bar 22 pass through the through hole 25 on the first compression plate 2. The electric lead screw 21 is used to drive the compression plate 2 to move in the loading chamber 1, and the slide bars 22 and the slider 24 are used to assist the electric lead screw 21 in driving the compression plate 2.
[0035] Preferred, such as Figure 1 and Figure 4As shown, a fixing plate 16 is provided inside the mounting channel 11; the first adsorption mechanism 3 includes a mounting plate 31 located in the middle of the mounting channel 11 and axially parallel to the height direction of the loading chamber 1, and a plurality of first suction cups 32 arranged in a circumferential array around the central axis of the mounting plate 31 on the lower surface of the mounting plate 31. In this example, a total of four first suction cups 32 are provided; the mounting plate 31 is fixed below the fixing plate 16, and the adsorption surfaces of the first suction cups 32 are all arranged perpendicular to the height direction and downward. The first suction cups 32 are all arranged extending out of the lower end of the mounting channel 11, and the circumferential array radius of the first suction cups 32 is... The size of the matching ring 61 is matched; the second adsorption mechanism 4 includes two mounting strips 41 respectively located at both ends of the mounting track 11, and a plurality of second suction cups 42 located on the lower surface of the mounting strips 41. In this example, there are two second suction cups 42 on one mounting strip 41; the mounting strips 41 are all fixed below the fixing plate 16, and the adsorption surfaces of the second suction cups 42 are all set downward perpendicular to the height direction. The adsorption surfaces of the second suction cups 42 are all coplanar with the adsorption surfaces of the first suction cups 32; the first suction cups 32 are used to adsorb the mesh tube 6, and the second suction cups 42 are used to adsorb the limiting frame 7.
[0036] Preferred, such as Figure 4 and Figure 5 As shown, an air supply pipe 33 is coaxially mounted on the mounting plate 31 on the fixed plate 16. The air supply pipe 33 passes through the fixed plate 16, and its lower end is connected to the lower surface of the mounting plate 31. A mounting bracket 34 is mounted on the upper end of the air supply pipe 33. A second rotating motor 35 with its drive shaft coaxially mounted on the mounting bracket 34 is mounted on the mounting bracket 34. A fan 36 is coaxially connected downwards to the drive shaft of the second rotating motor 35. The fan 36 is located inside the air supply pipe 33. With this design, the second rotating motor 35 is used to drive the fan 36 to supply air into the mesh pipe 6, and then to the bottom layer of Sichuan pepper. This not only makes the bottom layer of Sichuan pepper more loose to increase air permeability and heat dissipation, but also blows off the Sichuan pepper that is attached to the mesh pipe 6, making the upper layer of Sichuan pepper more flat and improving space utilization.
[0037] Preferred, such as Figure 1 , Figure 4 , Figure 6 As shown, both ends of the fixing plate 16 are connected to fixing strips 43. Each fixing strip 43 has a through-hole 44 extending along the height direction of the loading chamber 1. A mating rod 45 slides through each mating channel 44. The lower ends of the mating rods 45 are connected to mounting strips 41, and the upper ends of each mating rod 45 are connected to limiting heads 46, which are larger than the mating channels 44. Springs 47 are coaxially sleeved around the outer periphery of each mating rod 45. The upper end of the spring 47 is connected to the fixing strip 43, and the lower end is connected to the mounting strip 41. When the spring 47 is in its original state, the position of the second suction cup 42 in the height direction is lower than that of the first suction cup 32, and the limiting heads 46 are in contact with the fixing strips 43. This design allows the springs 47 to make the second suction cup 42 contact more tightly with the mating ears 71 on the limiting frame 7.
[0038] Preferred, such as Figure 7 As shown, the fixed plate 16 is equipped with a vacuum pump 5, a first vacuum chamber 51, and two second vacuum chambers 52. The working end of the vacuum pump 5 is connected to a three-way pipe 53, which is connected to the first vacuum chamber 51 and one of the second vacuum chambers 52. Each pipe connected to the three-way pipe 53 and the first vacuum chamber 51 and one of the second vacuum chambers 52 is equipped with an air valve 54. The first vacuum chamber 51 is connected to a number of first air pipes 55 matching the number of first suction cups 32. In this example, the first vacuum chamber 51 is connected to four first air pipes 55. The first air pipe 55 is connected to the first suction cup 32, and the second vacuum chamber 52 is connected to the second air pipe 56 in number matching the number of the second suction cups 42 on a single mounting strip 41. In this example, one second vacuum chamber 52 is connected to two second air pipes 56. The second air pipes 56 are connected to the second suction cups 42, and a connecting pipe 57 connects the two second vacuum chambers 52. With this design, by controlling the opening and closing of the air valve 54, only one vacuum pump 5 can be used to provide vacuum conditions for the first suction cup 32 and the second suction cup 42 respectively.
[0039] like Figure 8 As shown, another aspect of this embodiment provides a method for transporting Sichuan peppercorns into a warehouse, including the following steps:
[0040] S100. The cold storage is divided into several areas arranged in a grid pattern with rows a and columns b. The size of each grid matches the limit frame 7. All grids in the first row, column 1 and column b are set against the wall.
[0041] S200, the mobile loading bin 1 and the second adsorption mechanism 4 adsorb the limiting frame 7, fill all the grids in the first row with the limiting frame 7, and place a limiting frame 7 in the grid of the first column of the second row.
[0042] S300. The Sichuan peppercorns are loaded into the loading bin 1 and adsorbed through the first adsorption mechanism 3 and the mesh tube 6.
[0043] In each empty limiting frame 7, the Sichuan pepper and the mesh tube 6 are fed in;
[0044] S400. Let the current grid row filled with limit frames 7 be the xth row. Following the order from the 1st column to the (b-1)th column, the second adsorption mechanism sequentially removes the limit frames 7 from the yth column of the xth row and places them on the (x+1)th column of the (y+1)th row, where 1≤y≤b-1. Then, the limit frames 7 on the bth column of the xth row are removed and placed on the 1st column of the (x+2)th row. After placement, the process jumps back to S300 for execution.
[0045] Using this method, it is not necessary to prepare a large number of limiting frames 7 for the storage of Sichuan peppercorns, but only b+1 limiting frames 7 are needed; and when the number of limiting frames 7 is reduced, gas can circulate between the bottom layer of Sichuan peppercorns, which further prevents the Sichuan peppercorns from spoiling due to heat accumulation.
[0046] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.

9. A method for conveying Sichuan pepper into a warehouse, characterized in that, The method for controlling the Sichuan pepper storage conveying equipment as described in any one of claims 1 to 8 includes the following steps: S100. The cold storage is divided into several areas in a grid pattern, with a rows and b columns. The size of each grid matches the limit frame (7). All grids in the first row, the first column and the b column are set against the wall. S200, the mobile loading bin (1) and the second adsorption mechanism (4) adsorb the limiting frame (7), fill all the grids in the first row with the limiting frame (7), and place a limiting frame (7) in the first column of the second row. S300. The Sichuan pepper is loaded into the loading bin (1) and adsorbed through the first adsorption mechanism (3) and the mesh tube (6). In each empty limiting frame (7), the rattan pepper and the mesh tube (6) are fed; S400. Let the current grid row filled with limit frames (7) be the xth row. In the order from the first column of the grid to the (b-1)th column of the grid, the limit frames (7) of the yth column of the xth row are taken out by the second adsorption mechanism and placed on the (y+1)th column of the x+1th row, where 1≤y≤b-1. Then, the limit frames (7) on the bth column of the xth row are taken out and placed on the first column of the (x+2)th row. After placement, jump back to S300 to execute.
