Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material conveying technology, and more specifically, to a hoist. Background Technology
[0002] Stir-frying is a crucial step in food processing. Currently, companies typically use automatic stir-fryers to stir-fry raw materials. To process larger quantities of raw materials at once, the stir-fryers need to be designed to be quite large, resulting in a high loading height. When adding raw materials to these large stir-fryers, a lifting machine is usually used. Most current lifting machines are chain-type, which are bulky and occupy a significant amount of floor space. Furthermore, some sticky raw materials tend to remain in the lifting machine's feed cylinder, leading to incomplete unloading. Workers then need to tap the feed cylinder to shake the raw materials off into the stir-fryer, reducing the efficiency of material addition. Utility Model Content
[0003] The purpose of this invention is to provide a lifting machine that does not require a large space and allows for more thorough pouring of raw materials, thereby improving the efficiency of raw material addition.
[0004] This utility model is achieved through the following technical solution: a hoist, comprising: a housing, wherein a drive motor is disposed within the housing, the output shaft of the drive motor is connected to a drive shaft, and the drive shaft extends to the outside of the housing; a cantilever, one end of which is rotatably disposed outside the housing and fixedly connected to the drive shaft; a placement frame, which is rotatably disposed at the end of the cantilever away from the drive shaft via a rotating shaft, and a cylinder is placed on the placement frame; a chain drive mechanism, comprising a first sprocket, a second sprocket, and a chain, wherein the first sprocket is rotatably disposed on the drive shaft, the second sprocket is fixedly disposed on the rotating shaft of the placement frame, and the chain is connected between the first sprocket and the second sprocket; and a linkage mechanism, comprising a first link, a second link, and a pull plate that are hinged sequentially, wherein after the cantilever rotates to a vertically upward state, the pull plate can restrict the position of the second sprocket and cause the second sprocket to rotate relative to the cantilever.
[0005] Furthermore, the first connecting rod is rotatably mounted on the side wall of the housing and located on one side of the drive shaft, the second connecting rod is rotatably mounted on the first connecting rod, the pull plate is rotatably connected to the end of the second connecting rod away from the first connecting rod, and the pull plate is fixedly connected to the second sprocket.
[0006] Furthermore, when the cantilever is in a downward tilted state, the pulling plate is located in the area above the second sprocket; when the cantilever has passed through a vertical state and is in a downward tilted state, the pulling plate is located in the area below the second sprocket.
[0007] Furthermore, the linkage mechanism also includes a fixing block for fixing to the housing. The fixing block has a waist-shaped hole for bolts to pass through in the vertical direction. The housing has a corresponding threaded hole for bolts to be inserted. The first linkage is rotatably mounted on the fixing block.
[0008] Furthermore, when the cantilever is in a downward tilted state, the placement frame has a rotational tendency opposite to the rotation direction of the cantilever. The first sprocket is provided with an anti-rotation block to limit the reverse rotation of the placement frame, and the housing is provided with an anti-rotation post to abut against the anti-rotation block.
[0009] Furthermore, the top of the placement rack is provided with a limiting frame for limiting the position of the cylinder opening end, and one side of the placement rack is provided with an arc-shaped strip for limiting the position of the cylinder sidewall.
[0010] Furthermore, a support block is provided on the box body, and when the cantilever is in a downward tilted state, the pulling piece rests on the support block.
[0011] The technical solution of this utility model has at least the following advantages and beneficial effects: This invention uses a drive motor to rotate the cantilever, causing the placement rack to swing, so as to move the cylinder to the top side of the wok for loading. By setting up a chain drive mechanism and a linkage mechanism, the cylinder will not rotate on its own when it first rotates, but will rotate on its own after reaching the designated position to turn the raw materials into the wok, thereby improving the loading process.

Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0014] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0015] The following is for reference Figures 1-5 As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides a hoist, referring to... Figure 1 As shown, the device includes a housing 1, a cantilever 2, a placement rack 3, a chain drive mechanism 4, and a linkage mechanism 5. A drive motor 11 is installed inside the housing 1, and the output shaft of the drive motor 11 is connected to a drive shaft 12, which extends to the outside of the housing 1. One end of the cantilever 2 is rotatably mounted outside the housing 1 and fixedly connected to the drive shaft 12. The placement rack 3 is rotatably mounted at the end of the cantilever 2 away from the drive shaft 12 via a rotating shaft 31, and a cylinder 32 is placed on the placement rack 3. The drive motor 11 drives the drive shaft 12 to rotate, which in turn causes the cantilever 2 to swing around the drive shaft 12. The placement rack 3, mounted at the end of the cantilever 2, then moves the cylinder 32, allowing it to be moved to the top side of the wok for easy loading.
[0016] Reference Figure 2 , Figure 3As shown, the chain drive mechanism 4 includes a first sprocket 41, a second sprocket 42, and a chain 43. The first sprocket 41 is rotatably mounted on the drive shaft 12, and the second sprocket 42 is fixedly mounted on the rotating shaft 31 of the placement frame 3. The chain 43 connects the first sprocket 41 and the second sprocket 42. The linkage mechanism 5 includes a first connecting rod 51, a second connecting rod 52, and a pulling plate 53 that are hinged in sequence. (Refer to...) Figure 4 As shown, when the cantilever 2 rotates to a vertically upward position, the pull plate 53 can restrict the position of the second sprocket 42 and cause the second sprocket 42 to rotate relative to the cantilever 2. During the process of the cantilever 2 rotating from a downward tilted position to a vertical position, the second sprocket 42 always moves synchronously with the end of the cantilever 2 and remains relatively stationary. When the cantilever 2 continues to rotate from the vertical position, the pull plate 53 applies a pulling force to the second sprocket 42 to restrict the second sprocket 42 from moving synchronously with the cantilever 2. The second sprocket 42 and the cantilever 2 will rotate relative to each other, thereby driving the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, the cylinder 32 can be flipped to allow the raw materials to be poured into the wok more thoroughly.
[0017] Reference Figure 3 , Figure 4 As shown, when the cantilever 2 is tilted downwards, the pulling plate 53 is located in the area above the second sprocket 42, and the cylinder 32 is in its initial state and at its lowest height. After the cantilever 2 has passed through the vertical state and is tilted upwards, the pulling plate 53 is located in the area below the second sprocket 42. At this time, the cantilever 2 moves the cylinder 32 to the area above the wok, and the pulling plate 53 can pull the second sprocket 42 to cause the placement rack 3 to further rotate the cylinder 32 to facilitate the dumping of raw materials. (Refer to...) Figure 2 As shown, a support block 14 is also provided on the housing 1. When the cantilever 2 is tilted downward, the pull plate 53 is placed on the support block 14. The support block 14 can support the entire linkage mechanism 5, so as to reduce the tension on the linkage mechanism 5 and thus improve the service life of the linkage mechanism 5.
[0018] Reference Figure 3As shown, the linkage mechanism 5 also includes a fixing block 54 for fixing to the housing 1. The fixing block 54 is located on one side of the drive shaft 12. The fixing block 54 has a waist-shaped hole 541 for bolts to pass through in the vertical direction. The housing 1 has a corresponding threaded hole for bolt insertion. The first connecting rod 51 is rotatably mounted on the fixing block 54, and the second connecting rod 52 is rotatably mounted on the first connecting rod 51. The pulling plate 53 is rotatably connected to the end of the second connecting rod 52 away from the first connecting rod 51. The pulling plate 53 is fixedly connected to the second sprocket 42. When the fixing block 54 is fixed to the housing 1 by bolts, the fixing block 54 can be adjusted vertically through the waist-shaped hole 541. Then, the bolts are tightened to position the fixing block 54, which can change the overall installation height of the linkage mechanism 5. This changes the position of the pulling plate 53 when pulling the second sprocket 42, thereby adjusting the rotation angle of the cylinder 32.
[0019] Reference Figure 1 , Figure 5 As shown, the center of gravity of the overall structure of the placement rack 3 and the cylinder 32 is located on the side of the rotating shaft 31 away from the wok. Therefore, when the cantilever 2 is tilted downward, the placement rack 3 has a rotational tendency opposite to the rotation direction of the cantilever 2, that is, a tendency to rotate away from the wok. The first sprocket 41 is provided with an anti-rotation block 411 to limit the reverse rotation of the placement rack 3, and the housing 1 is provided with an anti-rotation post 13 to abut against the anti-rotation block 411. Under the contact action of the anti-rotation post 13 and the anti-rotation block 411, the first sprocket 41 cannot rotate under the drive of the second sprocket 42, and can restrict the second sprocket 42. Therefore, the placement rack 3 only has the tendency to rotate away from the wok and cannot rotate. When the cantilever 2 rotates upward to the vertical state, under the pulling action of the pulling piece 53, the second sprocket 42 can drive the placement rack 3 to have the tendency to rotate towards the wok. The anti-rotation block 411 and the anti-rotation post 13 will only restrict the first sprocket 41 to rotate in one direction and will not restrict the first sprocket 41 to rotate in the other direction. Therefore, when the second sprocket 42 drives the placement rack 3 to rotate towards the wok, the anti-rotation post 13 can move away from the anti-rotation block 411. After the raw materials are poured out, the drive motor 11 flips and drives the cantilever 2 to move back to the initial position. Since the center of gravity of the overall structure of the placement rack 3 and the cylinder 32 is located on the side of the rotating shaft 31 away from the wok, the placement rack 3 and the cylinder 32 can rotate back to the initial angle under the action of gravity until the anti-rotation column 13 abuts against the anti-rotation block 411 and then will not continue to rotate.
[0020] Reference Figure 5As shown, the top of the placement rack 3 is provided with a limiting frame 33 for limiting the position of the opening end of the cylinder 32, so as to restrict the movement of the cylinder 32 in the vertical direction. An arc-shaped strip 34 is provided on one side of the placement rack 3 for limiting the position of the side wall of the cylinder 32, so as to restrict the movement of the cylinder 32 in the horizontal direction.
[0021] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
