Description

Technical Field

[0001] The invention relates to the technical field of coffee bean raw material transportation, in particular to a coffee bean raw material containing device. Background Art

[0002] Green coffee beans (raw materials) and roasted coffee beans (raw materials after processing) are generally stored in different workshops, which can effectively prevent microorganisms, dust or other impurities in the green beans from contaminating the roasted beans, thereby ensuring the purity and quality of the roasted beans. When the raw materials need to be processed, the raw material holding device can be used to transport the raw materials from the raw material storage workshop to the processing workshop.

[0003] The raw material holding device is generally a cart-like tool, which is convenient for transporting raw materials. If there is no threshold or other obstacle on the road from the storage workshop to the processing workshop, the cart can be transported smoothly and without obstacles. If there is a threshold along the way, it will hinder the movement of the cart's wheels. The conventional solution is generally to manually pry one end of the cart to make the other wheel cross the threshold, and then keep this posture and push it for a short distance before putting down the other wheel, and use the same method to make the other wheel cross the threshold. This process requires workers to exert great strength to achieve, which brings high work intensity to the workers. In addition, inclined boards can be laid on both sides of the threshold to facilitate the passage of the cart, but the cart needs to move diagonally upward when passing through the inclined board on one side, which also requires workers to exert great strength to push it up. Overall, it will bring considerable work intensity to the workers. Summary of the invention

[0030] See also Figure 1-Figure 13In an embodiment of the present invention, a coffee bean raw material holding device comprises a shell 1, a feeding hole 101 is provided at the center of the shell 1, a plurality of magnetic suction rods 2 are transversely arranged at the feeding hole 101, a weighing sensor 3 is arranged on the shell 1, four grooves 102 are axially symmetrically provided at the bottom of the shell 1, a triangular plate 4 is fixedly provided in each of the grooves 102, a triangular groove 41 is provided in the triangular plate 4, a moving rod 5 is slidably provided in the triangular groove 41, a movable rod 6 is movably connected to one end of the moving rod 5 away from the triangular groove 41, a pulley 7 is provided at the bottom of the movable rod 6 for transmission, and an adjustment component 8 for driving the pulley 7 to move up and down is provided on the triangular plate 4; the coffee bean raw materials are poured into the shell 1 through the feeding hole 101, and the magnetic suction rods 2 can absorb the coffee bean raw materials Waste wire, iron core and other scraps mixed in the raw materials can be ensured to be clean. The weighing sensor 3 can accurately identify the weight of the poured raw materials, and a prompt sound will be issued when the preset weight is reached. After the raw materials are poured in, the shell 1 is pushed to move into the processing workshop. In the initial state, the moving rod 5 is located in the middle of the straight groove section below the triangular groove 41, and the movable rod 6 is in a vertical state. At this time, the pulley 7 is in contact with the ground, and the triangular plate 4 is fixedly connected to the inner wall of the groove 102. Therefore, pushing the shell 1 will drive the triangular plate 4, the movable rod 6 and the pulley 7 to move synchronously. When a threshold is encountered on the pushing route, the pulley 7 can be driven to move upward by adjusting the component 8 so that the height of the pulley 7 is higher than the height of the threshold. In this way, the pulley 7 can cross the threshold without prying one side of the shell 1, thereby reducing the labor intensity of workers during the raw material transportation process.

[0031] See also Figure 3-Figure 5As shown, in this embodiment, preferably, the adjustment assembly 8 includes a fixed frame 81, the fixed frame 81 is fixedly connected to the bottom of the triangular plate 4, a rotating rod 82 is movably provided at the center of the triangular plate 4, the other end of the rotating rod 82 movably passes through the shell 1 and is rotatably connected to another triangular plate 4 on the same side, a rotating plate 83 is fixedly connected to one side of the rotating rod 82, a sliding groove 84 is initially provided on the rotating plate 83, the moving rod 5 is slidably connected to the sliding groove 84, a moving block 85 is slidably provided in the fixed frame 81, and the movable rod 6 is slidably connected to the moving block 85; in the initial state, one end of the moving rod 5 is located in the middle of the straight groove section below the triangular groove 41 The sliding groove 84 section of the rotating plate 83 is also set vertically downward. At this time, the length of the movable rod 6 extending out of the groove 102 is the longest, and the pulley 7 just contacts the ground. When the threshold is still a distance away, the shell 1 is stopped and the rotating rod 82 is rotated. The rotation of the rotating rod 82 will drive the rotating plate 83 to rotate, thereby driving the moving rod 5 to move along the middle of the straight groove of the triangular groove 41 toward the threshold (i.e., the forward direction). When the moving rod 5 moves, the movable rod 6 will be driven to move synchronously. The movement of the movable rod 6 will drive the moving block 85 to slide along the fixed frame 81. In this process, the moving rod 5 will also move downward relative to the sliding groove 84. When the moving rod 5 reaches the end of the straight groove section of the triangular groove 41 When the moving rod 5 reaches the highest point of the triangular groove 41, the lifting height of the pulley 7 is the highest. The front two pulleys 7 can change their height by rotating the rotating rod 82 on the front side, and the rear two pulleys 7 are still in contact with the ground. At this time, it is only necessary to keep the front side of the shell 1 stable, and rely on the rear two pulleys 7 to make the front side of the shell 1 pass over the threshold. After passing the threshold, continue to rotate the rotating rod 82 in the same direction to rotate the rotating rod 82. The rotation of the movable rod 82 will drive the rotating plate 83 to rotate so that the moving rod 5 moves downward relative to the slide groove 84. At the same time, the moving rod 5 also moves downward obliquely from the highest point of the triangular groove 41 along the groove on the other side. During this process, the movable rod 6 moves downward relative to the moving block 85 until the moving rod 5 reaches the straight groove section of the triangular groove 41. At this time, the two pulleys 7 on the front side are in contact with the ground on the other side of the threshold. Continuing to rotate the rotating rod 82 in the same direction will cause the moving rod 5 to move horizontally to the middle of the straight groove section of the triangular groove 41 (i.e., the initial position). At this point, the two pulleys 7 on the front side can cross the threshold. The same method can be used for the two pulleys 7 on the rear side. The moving trajectory of the pulley 7 can approximately form a "triangle".

[0032] See also Figure 2 , Figure 3 and Figure 6-Figure 7As shown, in this embodiment, preferably, notches 103 are axially symmetrically provided on the front and rear sides of the shell 1, the rotating rod 82 movably passes through the notch 103, a positioning block 9 is fixedly provided in the notch 103, the rotating rod 82 movably passes through the positioning block 9, a positioning wheel 11 is fixedly provided on one side of the rotating rod 82, a plurality of positioning grooves 111 are provided in an annular array on the positioning wheel 11, a positioning frame 10 is rotatably provided on the top of the positioning block 9, the positioning frame 10 is movably engaged with the positioning groove 111, a fixing cylinder 12 is fixed on the top of the positioning block 9, and the fixing cylinder 11 2 is movably provided with a lifting cylinder 13, and a positioning spring 14 is fixedly provided between the lifting cylinder 13 and the fixed cylinder 12, and the top of the lifting cylinder 13 is movably abutted against the side of the positioning frame 10 away from the positioning groove 111; in the initial state, the pulley 7 is abutted against the ground, and at this time, one side of the positioning frame 10 in the notch 103 is engaged with the positioning groove 111, and at this time, the positioning wheel 11 is in a state where it cannot rotate, and the rotating rod 82 cannot rotate accordingly, so the state of the rotating plate 83 will not change, and the states of the moving rod 5, the movable rod 6 and the pulley 7 will remain stable, so that the plane can be pushed in the process The stability of the pulley 7, when encountering a threshold and needing to adjust the height of the pulley 7, the side of the positioning frame 10 away from the positioning groove 111 is pressed downward to make the side move downward, thereby driving the lifting cylinder 13 to move downward relative to the fixed cylinder 12 and then compressing the positioning spring 14, and the other end of the positioning frame 10 will be released from the positioning groove 111. At this time, the positioning wheel 11 and the rotating rod 82 can be rotated to drive the purpose of adjusting the height of the pulley 7. When the moving rod 5 moves to the highest point of the triangular groove 41, the height of the pulley 7 is the highest. At this time, the housing 1 is pushed to move while keeping the housing 1 stable. In this process, the positioning can be removed. The force applied by the positioning frame 10 will drive one end of the positioning frame 10 to be lifted up under the action of the positioning spring 14 so that the other end of the positioning frame 10 will be re-engaged with the positioning groove 111, thereby ensuring the stability of the pulley 7 in the lifted state. When the shell 1 is pushed a short distance so that the front pulley 7 passes the threshold, the engagement between the positioning frame 10 and the positioning groove 111 is released again, and the next adjustment can be carried out. The positioning block 9 provides a supporting effect. In this step, the engagement between the positioning frame 10 and the positioning groove 111 can ensure that the pulley 7 can maintain a certain stability in both the sliding and lifted states.

[0033] See also Figure 5 and Figure 8As shown, in this embodiment, preferably, a limiting frame 15 is fixedly provided on one side of the fixing frame 81, a vertical rod 16 is rotatably provided in the limiting frame 15, a rotating column 17 is fixedly sleeved on the outer side of the vertical rod 16, and a curved groove 171 is provided on the rotating column 17, a lifting rod 18 is movably provided on the limiting frame 15, and the bottom of the lifting rod 18 is movably abutted against the curved groove 171, a vertical groove 151 is provided on one side of the limiting frame 15, a lifting plate 19 is slidably provided in the vertical groove 151, one side of the lifting plate 19 is fixedly connected to the lifting rod 18, and a transmission device 10 is provided on the other side of the lifting plate 19. A support wheel 20 is arranged; in the initial state, the pulley 7 is in contact with the ground, the support wheel 20 is suspended, and one end of the lifting rod 18 is in contact with the high point of the curved groove 171. When the rotation of the rotating rod 82 drives the moving rod 5 to move along the middle of the straight groove section of the triangular groove 41 to the end of the straight groove section, the pulley 7 moves parallel to the ground during this process, and the vertical rod 16 is rotated. The rotation of the vertical rod 16 will drive the rotating column 17 to rotate so that one end of the positioning rod moves along the high point of the curved groove 171 to the low point, and the lifting rod 18 will move downward, thereby driving the lifting plate 19 to move downward along the vertical groove 151 opened by the limiting frame 15, thereby causing the support wheel 20 to move downward. The movable rod 5, the movable rod 6 and the pulley 7 are moved downward until they abut against the ground, and then the continuous rotation of the rotating rod 82 drives the movable rod 5, the movable rod 6 and the pulley 7 to move upward. During this process, the vertical rod 16 and the rotating column 17 do not rotate, and the supporting wheel 20 continues to abut against the ground, and then the shell 1 is kept stable and pushed forward to make the two pulleys 7 on the front side cross the threshold until the supporting wheel 20 is about to touch the threshold and stops. The supporting wheel 20 can provide support for the movement of the shell 1 in this process. The horizontal distance between the supporting wheel 20 and the pulley 7 should be far enough, because the rotating rod 82 will drive the pulley 7 to move downward during the subsequent rotation. If the pulley 7 and the supporting wheel 20 are The distance between the wheels 20 is relatively close, which will cause the triangle plate 4 to not pass over the threshold as a whole. Then, the pulley 7 will collide with the threshold during its downward movement. When the pulley 7 moves downward to the lowest point and contacts the ground, it will slide parallel to the ground for a distance, because the moving rod 5 will slide along the end of the straight groove section of the triangle groove 41 to the middle of the straight groove section. During this process, continuing to rotate the vertical rod 16 and the rotating column 17 in the same direction will cause one end of the lifting rod 18 to move along the lower part of the curved groove 171 to the higher part, thereby causing the supporting wheel 20 to move upward to the initial position, so that the shell 1 can be pushed so that the front side of the shell 1 as a whole passes over the threshold.

The clockwise rotation of the gear 21 will drive the ring 22 to rotate synchronously. When rotating in this direction, the sawtooth block 23 is not engaged with the sawtooth groove 221, so the rotation of the ring 22 will drive the sawtooth block 23 to move downward, thereby compressing the limit spring 24, thereby not driving the sawtooth block 23 to rotate, the vertical rod 16 does not rotate, and the state of the support wheel 20 remains unchanged.

When rotating in this direction, the vertical rod 16 will be driven to rotate, so that the support wheel 20 moves downward until it abuts against the ground. When the moving rod 5 moves obliquely upward along the groove on one side of the triangular groove 41, the pulley 7 is lifted upward, and the moving block 85 will move in the opposite direction to the initial position. In this process, the first rack 2 5 will drive the gear 21 to rotate clockwise, and the state of the support wheel 20 remains unchanged. Then the support wheel 20 can facilitate the short-distance movement of the shell 1. Then the moving rod 5 moves obliquely downward along the highest point of the triangular groove 41 to the straight groove section. During this process, the second rack 26 will be driven to engage with the gear 21 to make the gear 21 rotate clockwise, and the state of the support wheel 20 will not change. During the movement of the moving rod 5 to the initial position along the straight groove section, the moving block 85 moves in the opposite direction to the initial position along the fixed frame 81. During this process, the second rack 26 will be engaged with the gear 21 again to drive the gear 21 to rotate counterclockwise. The rotation in this direction will drive the vertical rod 16 to rotate, so that the support wheel 20 moves upward to the initial position, which can facilitate the front side of the shell 1 to cross the threshold as a whole.

The height of the limit block 35 is higher than the height of the push block 33 to avoid the push block 33 from colliding with the limit block 35 during the movement.

[0040] The working principle of the present invention is as follows: the coffee bean raw material is poured into the shell body 1 through the feed hole 101. In the initial state, one end of the moving rod 5 is located in the middle of the straight groove section below the triangular groove 41, and the slide groove 84 section provided by the rotating plate 83 is also vertically arranged downward. At this time, the length of the movable rod 6 extending out of the groove 102 is the longest, and the pulley 7 just abuts against the ground. When the threshold is encountered and there is still a distance, the shell body 1 is stopped and the rotating rod 82 is rotated. The rotation of the rotating rod 82 will drive the rotating plate 83 to rotate, thereby driving the moving rod 5 to move along the middle of the straight groove of the triangular groove 41 in the direction close to the threshold (i.e., the forward direction). When the moving rod 5 moves, it will drive the movable rod 6 to move synchronously together. The movement of the movable rod 6 will drive the moving block 85 to move along the fixed frame 81 When sliding occurs, the moving rod 5 will also move downward relative to the sliding groove 84 during this process. When the moving rod 5 reaches the end of the straight groove section of the triangular groove 41, continuing to rotate the rotating rod 82 in the same direction will drive the moving rod 5 to move obliquely upward along the groove on one side of the triangular groove 41, and will drive the movable rod 6 to move upward along the moving block 85, thereby raising the height of the pulley 7. During this process, the moving rod 5 moves upward relative to the sliding groove 84 and returns to the initial position. When the moving rod 5 reaches the highest point of the triangular groove 41, the lifting height of the pulley 7 is the highest at this time. The front two pulleys 7 can achieve a change in height by rotating the rotating rod 82 on the front side, and the rear two pulleys 7 are still in contact with the ground. At this time, it is only necessary to keep the front side of the shell 1 stable, and rely on the rear two pulleys 7 to make the shell 1 The front side of the mobile rod 8 passes over the threshold, and after passing over the threshold, the rotating rod 82 is continuously rotated in the same direction. The rotation of the rotating rod 82 drives the rotating plate 83 to rotate so that the moving rod 5 moves downward relative to the sliding groove 84. At the same time, the moving rod 5 also moves downward obliquely from the highest point of the triangular groove 41 along the groove on the other side. In this process, the movable rod 6 moves downward relative to the moving block 85 until the moving rod 5 reaches the straight groove section of the triangular groove 41. At this time, the two pulleys 7 on the front side abut against the ground on the other side of the threshold. Continuing to rotate the rotating rod 82 in the same direction will cause the moving rod 5 to move horizontally to the middle of the straight groove section of the triangular groove 41 (i.e., the initial position). At this point, the two pulleys 7 on the front side can pass over the threshold. The two pulleys 7 on the rear side can be used in the same way. The moving trajectory of the pulley 7 can be approximately A "triangle" is formed. At the same time, when the moving rod 5 moves toward the end along the middle of the straight groove section of the triangular groove 41, the moving block 85 also moves horizontally along the fixed frame 81, thereby driving the first rack 25 to move and drive the gear 21 to rotate counterclockwise. When rotating in this direction, the vertical rod 16 will be driven to rotate, so that the support wheel 20 moves downward until it abuts against the ground. When the moving rod 5 moves obliquely upward along the groove on one side of the triangular groove 41, the pulley 7 is lifted upward, and the moving block 85 will move in the opposite direction to the initial position. During this process, the first rack 25 will drive the gear 21 to rotate clockwise, and the state of the support wheel 20 remains unchanged. Then the support wheel 20 can facilitate the short-distance movement of the shell 1, and then the moving rod 5 moves obliquely downward along the highest point of the triangular groove 41 to the straight groove section.During this process, the second rack 26 will be driven to mesh with the gear 21, causing the gear 21 to rotate clockwise, and the state of the support wheel 20 will not change. During the movement of the moving rod 5 to the initial position along the straight groove section, the moving block 85 will move in the opposite direction to the initial position along the fixed frame 81. During this process, the second rack 26 will mesh with the gear 21 again, driving the gear 21 to rotate counterclockwise. This direction of rotation will drive the vertical rod 16 to rotate, thereby moving the support wheel 20 upward to the initial position, which can facilitate the front side of the shell 1 to cross the threshold as a whole. In addition, when the moving block 85 moves to one side along the middle of the fixed frame 81, it will drive the push block 33 to move synchronously. After moving a certain distance, the push block 33 will move with the horizontal movement The block 31 abuts, and the inclined grooves 34 of the two abut together, which will drive the lateral block 31 to move along the movable groove 291 to the inside of the movable block 29, thereby compressing the connecting spring 32. During this process, the movable block 29 will not move, so at the same time, the first rack 25 will drive the gear 21 to rotate counterclockwise to rotate the vertical rod 16 and the rotating column 17, and the support wheel 20 will move downward. Then, the moving block 85 will move in the opposite direction to the initial position. During the return process, the push block 33 and the side of the lateral block 31 without the inclined groove 34 will abut together, thereby driving the lateral block 31 and the movable block 29 to move synchronously together. During this process, the plug rod 28 will be engaged with the socket 191, which can ensure the stability of the support wheel 20.
