Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, specifically to a track drive mechanism for a double-layer tracked machine. Background Technology

[0002] A color sorter is a device that automatically separates discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology. It typically includes a feeding device, a color sorting device, and a sorting device. The material is fed through the feeding device. The color sorting device uses a camera to photograph the material and analyze its color or impurities, then sends a corresponding classification signal to the sorting device. The sorting device classifies the material according to the classification signal. The material is conveyed using a conveyor belt.

[0003] Reference patent (publication number: CN216369050U; publication date: 2022-04-26) discloses a double-layer four-channel tracked color sorter, including a frame, a feeding device, a color sorting device, and a distributing device. The color sorting device includes a first color sorting device and a second color sorting device. The distributing device includes a first distributing device and a second distributing device. The frame includes an upper frame and a lower frame located below the upper frame. The feeding device and the first color sorting device are respectively disposed at both ends of the upper frame. The second color sorting device is disposed on the lower frame and located below the feeding device. The first distributing device and the second distributing device are respectively disposed below the first color sorting device and the second color sorting device. A first conveying device is disposed on the upper frame and between the feeding device and the first color sorting device. A second conveying device is disposed on the lower frame and between the first distributing device and the second color sorting device.

[0004] Traditional color sorters often only perform single-pass sorting. For complex materials or materials with high impurity content, single-pass sorting often fails to achieve the desired sorting effect. Furthermore, the track drive mechanism of the tracked machine tends to cause material stacking during material transport, making it difficult to flatten the material. This leads to overlapping and obstruction of materials during transport, making it difficult for the optical detection system to clearly capture the optical characteristics of each material. Consequently, the recognition rate and sorting accuracy of the color sorter are affected. Therefore, this utility model provides a track drive mechanism for a double-layer tracked machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a track drive mechanism for a double-layer tracked machine, which solves the problem that track drive mechanisms for tracked machines are prone to causing material stacking during material conveying, making it difficult to flatten the material, and causing material to overlap and obstruct the material during the conveying process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a track drive mechanism for a double-layer tracked machine, comprising a first support frame, on which a drive mechanism for material conveying is mounted, the drive mechanism comprising:

[0007] The leveling assembly includes a support rod fixedly connected to the inner wall of a first support frame, a slide rail bracket fixedly connected to the end of the support rod, a slider slidably connected inside the slide rail bracket, a gear frame fixedly connected to the front end of the slider, and second limiting plates fixedly connected to both ends of the slide rail bracket. A reciprocating screw is rotatably connected to the inner wall of the second limiting plate, and the slider and the reciprocating screw are threadedly connected.

[0008] The material conveying assembly includes a drive shaft rotatably connected inside a first support frame. A connecting roller is provided at the end of the drive shaft. A first track for material conveying is provided on the outer wall of the connecting roller. A second track is connected to the outer wall of the drive shaft through a transmission assembly.

[0009] Preferably, the transmission assembly includes a transmission belt that is fitted to the outer wall of the drive shaft, a transmission shaft at the end of the transmission belt, a third gear at the right end of the transmission shaft, a fourth gear at the lower inner wall of the first support frame, a connecting shaft at the extended end of the fourth gear, the second track located on the outer wall of the connecting shaft, and the third gear and the fourth gear being meshed together.

[0010] Preferably, a first gear is provided on the outer wall of the drive shaft near the first support frame, and a second gear is provided on the inner wall of the first support frame above the first gear. The second gear is meshed with the first gear and is fixedly connected to one end of the reciprocating lead screw.

[0011] Preferably, the top of the first support frame is provided with a feeding bracket, and the lower end face of the feeding bracket is provided with a feeding plate.

[0012] Preferably, a fixing rod is fixedly connected to the left side wall of the first support frame, and a second support frame is fixedly connected to the end of the fixing rod.

[0014] Beneficial effects

[0015] This utility model provides a track drive mechanism for a double-layer tracked machine. Compared with the prior art, it has the following advantages:

[0016] Firstly, the reciprocating screw of this invention, when rotating, drives the slider to slide back and forth along the inside of the slide rail bracket. This causes the gear frame at the front end of the slider to swing on the first track, breaking up and spreading the material on the first track. This reduces the overlap and obstruction between materials, allowing the optical detection system to more clearly capture the optical characteristics of each material. This helps improve the recognition rate and sorting accuracy of the color sorter, prevents a decrease in processing speed due to local material accumulation, and avoids the formation of high-pressure zones on the track, thereby reducing friction and compression between materials. At the same time, the slide rail bracket is fixed with second limiting plates at both ends to block the material on both sides of the first track, preventing side leakage that may occur during track movement. This ensures that the material remains within the effective working area of ​​the track, thus improving the stability of the color sorter.

[0017] Secondly, this invention uses a single motor drive, and then achieves power distribution and transmission through gear meshing and transmission belts, making the entire equipment structure compact and reducing the floor space required. The first track transports materials to the sorting machine area for sorting, and then feeds them onto the first feeding support. Defective products are then fed onto the second track after sorting, and collected and sorted by the second feeding support. This allows for secondary or more refined sorting of materials. If the first track fails to completely separate all defective products, the second track can serve as a supplement to further remove foreign objects and discolored materials, ensuring the quality of the final product and thus improving overall processing efficiency and output.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a track drive mechanism for a double-layer tracked machine, including a first support frame 1, on which a drive mechanism for material conveying is provided, the drive mechanism including:

[0025] The leveling assembly includes a support rod 2 fixedly connected to the inner wall of a first support frame 1. A slide rail bracket 201 is fixedly connected to the end of the support rod 2. A slider 202 is slidably connected inside the slide rail bracket 201. A gear frame 205 is fixedly connected to the front end of the slider 202. Second limiting plates 203 are fixedly connected to both ends of the slide rail bracket 201. A reciprocating screw 204 is rotatably connected to the inner wall of the second limiting plate 203. The slider 202 and the reciprocating screw 204 are threadedly connected. When the reciprocating screw 204 rotates, it drives the slider 202 to slide reciprocally along the interior of the slide rail bracket 201, thereby causing the gear frame 205 at the front end of the slider 202 to swing on the first track 401. The material on the first track 401 is dispersed and spread out on the track, which reduces the overlap and obstruction between materials, allowing the optical detection system to capture the optical characteristics of each material more clearly. This helps to improve the recognition rate and sorting accuracy of the color sorter. It also prevents the processing speed from decreasing due to local material accumulation and avoids the formation of high-pressure zones on the track, thereby reducing friction and compression between materials. At the same time, the slide rail bracket 201 is fixed with second limiting plates 203 at both ends to block the material on both sides of the first track 401, preventing side leakage that may occur during track movement. This ensures that the material can be kept within the effective working area of ​​the track, thereby improving the stability of the color sorter.

[0026] The material conveying assembly includes a drive shaft 3 rotatably connected inside the first support frame 1. A connecting roller 4 is provided at the end of the drive shaft 3. A first track 401 for material conveying is provided on the outer wall of the connecting roller 4. A second track 505 is connected to the outer wall of the drive shaft 3 through a transmission assembly. The material is first conveyed by the first track 401 and then sent to the sorting machine area for sorting. It is then sent to the first feeding bracket 6. Defective products are then sent to the second track 505 for sorting and collection by the second feeding bracket 7. This allows for secondary sorting or finer sorting of materials. If the first track 401 fails to completely separate all defective products, the second track 505 can be used as a supplement to further remove foreign objects and discolored materials, ensuring the quality of the final product and thus improving the overall processing efficiency and output.

[0027] In a preferred embodiment, the transmission assembly includes a transmission belt 5 that is fitted to the outer wall of the drive shaft 3. A drive shaft 501 is located at the end of the transmission belt 5. A third gear 502 is located at the right end of the drive shaft 501. A fourth gear 503 is located on the lower inner wall of the first support frame 1. A connecting shaft 504 is located at the extended end of the fourth gear 503. A second track 505 is located on the outer wall of the connecting shaft 504, and the third gear 502 is meshed with the fourth gear 503. The drive shaft 3 is driven by a motor, which in turn drives the connecting roller shaft 4. The drive shaft 3 drives the first track 401, and then drives the transmission shaft 501 to rotate on the inner wall of the first support frame 1 through the transmission belt 5. At the same time, it drives the rotation of the third gear 502, and the third gear 502 and the fourth gear 503 are meshed together, so that the connecting shaft 504 is driven on the inner wall of the first support frame 1, thereby driving the second track 505. Due to the meshing transmission of the third gear 502 and the fourth gear 503, the first track 401 and the second track 505 can move in opposite directions.

[0028] In a preferred embodiment, a first gear 301 is provided on the outer wall of the drive shaft 3 near the first support frame 1, and a second gear 302 is provided on the inner wall of the first support frame 1 above the first gear 301. The second gear 302 is meshed with the first gear 301, and the second gear 302 is fixedly connected to one end of the reciprocating screw 204. When the drive shaft 3 is driven, it can drive the first gear 301 to rotate. The second gear 302 is meshed with the first gear 301, driving the reciprocating screw 204 to work.

[0029] In a preferred embodiment, a feeding bracket 8 is provided at the top of the first support frame 1, and a feeding plate 801 is provided on the lower end face of the feeding bracket 8 for feeding materials and then conveying them to the first track 401 through the feeding plate 801.

[0030] In a preferred embodiment, a fixing rod 102 is fixedly connected to the left side wall of the first support frame 1, and a second support frame 101 is fixedly connected to the end of the fixing rod 102. A first feeding bracket 6 is provided on the inner wall of the second support frame 101 for conveying the material sorted by the sorting machine through the first track 401. A second feeding bracket 7 is provided on the lower inner wall of the first support frame 1 below the second track 505. A first limiting plate 103 is fixedly connected to the inner wall of the fixing rod 102, and the first limiting plate 103 has an L-shaped structure. The first limiting plate 103 is distributed on both sides of the second track 505 to block the material on both sides. It should be noted that the sorting equipment involved is prior art and will not be described in detail.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the material is conveyed onto the first track 401 via the feed plate 801. The drive shaft 3 is then driven by a motor, which in turn drives the connecting roller shaft 4, controlling the movement of the first track 401. Simultaneously, the drive shaft 3 drives the transmission shaft 501 to rotate on the inner wall of the first support frame 1 via the transmission belt 5, which in turn drives the rotation of the third gear 502. The third gear 502 and the fourth gear 503 are meshed, enabling the connecting shaft 504 to transmit power on the inner wall of the first support frame 1, thereby driving the second track 505. Because the third gear 502 and the fourth gear 503 are meshed... Under the meshing transmission of 3, the first track 401 and the second track 505 can move in opposite directions. The first track 401 conveys the material and then sends it to the sorting machine area for sorting. The material is then fed onto the first feeding bracket 6. Defective products are then fed onto the second track 505 and collected and sorted by the second feeding bracket 7. This allows for secondary sorting or finer sorting of materials. If the first track 401 fails to completely separate all defective products, the second track 505 can be used as a supplement to further remove foreign objects and discolored materials, ensuring the quality of the final product.

[0033] The drive shaft 3, while driving, can simultaneously drive the rotation of the first gear 301. The second gear 302 is meshed with the first gear 301, driving the reciprocating screw 204 to work. This causes the gear frame 205 at the front end of the slider 202 to swing on the first track 401, breaking up and spreading the material on the first track 401. This reduces the overlap and obstruction between materials, allowing the optical detection system to more clearly capture the optical characteristics of each material, which helps improve the recognition rate and sorting accuracy of the color sorter.
