[0007] Furthermore, the roller has a through hole, and the pressure rod is slidably embedded in the through hole.

[0008] Furthermore, the anti-return pawl is rotatably mounted on the U-shaped frame via a hinge bolt. The hinge bolt is provided with an elastic element for driving the anti-return pawl to reset, and the anti-return pawl is provided with a pull ring for driving the anti-return pawl to release the ratchet.

[0009] Furthermore, the opening of the hook is provided with a slipknot to prevent the tightening rope from slipping off.

[0010] Furthermore, the locking mechanism includes a first belt buckle disposed on a first end of the belt, a second belt buckle disposed on a second end of the belt, and a locking connecting crossbar for connecting the first belt buckle and the second belt buckle.

[0015] This utility model has the following beneficial effects:

[0016] This utility model relates to an installation device for a tomato harvester conveyor belt. When disassembling the tomato harvester conveyor belt, one end of the tensioning rope is connected to a rotating roller, and the other end passes through both ends of the conveyor belt and connects to hooks. The operator pushes the pressure bar upwards, causing the rotating roller to rotate clockwise by a certain angle. Simultaneously, the rotating roller drives the ratchet to rotate clockwise by a certain angle, and the check pawl slides on the back of the ratchet teeth. As the rotating roller rotates, the tensioning rope wraps around it, causing the belt crossbars at both ends to continuously move closer together, stopping the force applied to the pressure bar. When the ratchet rotates counterclockwise, the check pawl inserts into the ratchet's tooth groove, preventing the ratchet from rotating counterclockwise. At this point, the tension at the connection points of the two ends of the tomato harvester conveyor belt disappears, facilitating the operator's disassembly of the locking mechanism. After disassembly, pulling the check pawl releases the force on the ratchet, causing the rotating roller to rotate and loosen the tensioning rope. The tensioning rope can then be removed from the hooks, allowing the installation device to be taken off. The tomato harvester can then be assembled... When installing the tomato harvester conveyor belt, one end of the tensioning rope is connected to the rotating roller, and the other end passes through both ends of the conveyor belt and connects to the hook. The operator pushes the two pressure rods upward, causing the rotating roller to rotate clockwise at a certain angle. At the same time, the rotating roller drives the two ratchet wheels on the left and right to rotate clockwise at a certain angle. The anti-return pawl slides on the back of the ratchet teeth. Under the rotation of the rotating roller, the tensioning rope is wound around the rotating roller, causing the belt crossbars at both ends to continuously move closer until the two ends of the tomato harvester conveyor belt can be connected. After the operator completes the connection of the locking mechanism at both ends of the tomato harvester conveyor belt, the anti-return pawl is pulled to release the force on the ratchet. The rotating roller rotates back to release the tensioning rope, and the tensioning rope can be removed from the hook to remove the installation device. Its structure is simple and easy to operate. The U-shaped frame does not need to be fixed to the foundation fixture, making it suitable for the installation of tomato harvester conveyor belts. It can reduce the labor intensity of disassembling and assembling tomato harvester conveyor belts and improve the efficiency of disassembly and assembly.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] Please refer to the following: Figures 1 to 5 The installation device for the conveyor belt of a tomato harvester in this embodiment includes a U-shaped frame 41, a rotating roller 42 rotatably arranged on the U-shaped frame 41, a ratchet 43 arranged on the rotating roller 42, a check pawl 44 arranged on the U-shaped frame 41 for locking the ratchet 43, a tensioning rope 45 with its first end arranged on the rotating roller 42, a hook 46 arranged on the U-shaped frame 41 for connecting the second end of the tensioning rope 45, and a pressure bar 47 for driving the rotating roller 42 to rotate relative to the U-shaped frame 41. The tomato harvester conveyor belt includes two parallel belts 1, belt crossbars 2 spaced apart on the belts 1, and a locking mechanism 3 for connecting the two ends of the belts 1. The locking mechanism 3 is disassembled / assembled by tensioning the two ends of the tomato harvester conveyor belt by the tensioning rope 45.

[0028] In this embodiment, the installation device for the conveyor belt of a tomato harvester involves the following steps: When disassembling the conveyor belt, one end of the tightening rope 45 is connected to the rotating roller 42, and the other end passes through both ends of the conveyor belt and connects to the hook 46. The operator pushes the pressure rod 47 upwards, causing the rotating roller 42 to rotate clockwise by a certain angle. Simultaneously, the rotating roller 42 drives the ratchet 43 to rotate clockwise by a certain angle, and the anti-return pawl 44 slides on the back of the teeth of the ratchet 43. Under the rotation of the rotating roller 42, the tightening rope 45 wraps around it, causing the belt at both ends to... As the crossbar 2 moves closer, it stops applying force to the pressure bar 47. When the ratchet 43 rotates counterclockwise, the check pawl 44 inserts into the tooth groove of the ratchet 43, preventing the ratchet 43 from rotating counterclockwise. At this time, the tension at both ends of the conveyor belt of the tomato harvester disappears, making it easier for the operator to disassemble the locking mechanism 3. After the locking mechanism 3 is disassembled, the check pawl 44 is pulled to release the force on the ratchet 43, and the roller 42 rotates to loosen the tension rope 45. The tension rope 45 can then be removed from the hook 46, and the installation device can be taken off. When attaching the conveyor belt to the tomato harvester, one end of the tensioning rope 45 is connected to the rotating roller 42, and the other end passes through both ends of the tomato harvester conveyor belt and is connected to the hook 46. The operator pushes the two pressure rods 47 upwards, and the rotating roller 42 rotates clockwise by a certain angle. At the same time, the rotating roller 42 drives the two ratchet wheels 43 on the left and right to rotate clockwise by a certain angle. The anti-return pawl 44 slides on the back of the teeth of the ratchet wheel 43. Under the rotation of the rotating roller 42, the tensioning rope 45 is wound around the rotating roller 42, causing the belt crossbars 2 at both ends to continuously move closer until the tomato harvester conveyor belt... The two ends of the conveyor belt can be connected. After the operator connects the locking mechanisms 3 at both ends of the tomato harvester conveyor belt, they pull the anti-return pawl 44 to release the force on the ratchet 43. The roller 42 rotates and loosens the tension rope 45. The tension rope 45 can then be removed from the hook 46, and the installation device can be taken off. Its structure is simple and easy to operate. The U-shaped frame 41 does not need to be fixed to the foundation, making it suitable for installing tomato harvester conveyor belts. This reduces the labor intensity of disassembling and assembling the tomato harvester conveyor belt and improves the efficiency of disassembly and assembly. Optionally, there are two ratchet wheels 43, symmetrically arranged on the roller 42. Correspondingly, there are two anti-return pawls 44, ensuring balanced force on the roller 42 and preventing tilting when only one end of the roller 42 is under force. Optionally, the anti-return pawls 44 on both sides have two teeth, ensuring better safety and reliability under heavy loads. Optionally, there are two pressure rods 47, which are connected to both ends of the rotating roller 42 respectively, to prevent the rotating roller 42 from tilting when only one end is under force.

[0029] like Figure 2 and Figure 3As shown, in this embodiment, the rotating roller 42 includes two symmetrically arranged bow-shaped rods 421. The arc segment of the bow-shaped rod 421 is a minor arc. The ratchet 43 has a bow-shaped hole 431 adapted to the bow-shaped rod 421. A pin 48 is arranged on the bow-shaped rod 421. The pin 48 cooperates with the U-shaped frame 41 to limit the axial position of the ratchet 43 on the rotating roller 42. The minor arcs of the two bow-shaped rods 421 are on the same circumference, ensuring that the rotating roller 42 can rotate smoothly on the U-shaped frame 41. Using two bow-shaped rods 421 to form the rotating roller can reduce the weight of the rotating roller 42, thereby reducing the weight of the entire device. The weight is light, making it easy for operators to move the device; the two bow-shaped rods 421 have the same structure and are symmetrically arranged during assembly, which reduces the difficulty of processing and makes installation convenient without the need for deliberate differentiation; the bow-shaped hole 431 on the U-shaped frame 41 can restrict the rotation of the bow-shaped rods 421, and the gap between the two bow-shaped rods 421 is used to pass through the tightening rope 45, ensuring that the tightening rope 45 can be firmly connected to the rotating roller 42; the ratchet 43 is limited by the side plate of the U-shaped frame 41 and the pin 48, which has a simple structure, is easy to disassemble and assemble, and can ensure that the ratchet 43 and the check pawl 44 are always engaged.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the roller 42 has a through hole, and the pressure rod 47 is slidably embedded in the through hole, which can prevent the pressure rod 47 from interfering with the belt crossbar 2. Optionally, limit blocks are provided at both ends of the pressure rod 47 to prevent the pressure rod 47 from slipping off.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the check pawl 44 is rotatably mounted on the U-shaped frame 41 via a hinge bolt 441. An elastic element 442 for driving the check pawl 44 to reset is mounted on the hinge bolt 441. A pull ring 443 for pulling the check pawl 44 to release the ratchet 43 is mounted on the check pawl 44. When assembling the tomato harvester conveyor belt, one end of the tightening rope 45 is connected to the rotating roller 42, and the other end passes through both ends of the tomato harvester conveyor belt and is connected to the hook 46. The pressure rod 47 is slid to its longest position to the left of the rotating roller 42. The operator pushes the two pressure rods 47 upwards, causing the rotating roller 42 to rotate clockwise by a certain angle. Simultaneously, the rotating roller 42 drives the two ratchet wheels 43 to rotate clockwise by a certain angle. The check pawl 44 slides on the back of the teeth of the ratchet wheels 43, and the tightening rope 45 winds around under the rotation of the rotating roller 42. On the rotating roller 42, the belt crossbars 2 at both ends are brought closer together. When the rotating roller 42 rotates 180°, the force applied to the pressure bar 47 stops. When the ratchet 43 rotates counterclockwise, the check pawl 44, under its own weight and the action of the elastic element 442, inserts into the tooth groove of the ratchet 43, preventing the ratchet 43 from rotating counterclockwise. At this time, the pressure bar 47 rotates to the right side of the rotating roller 42 and slides to the left side of the rotating roller 42 to its longest position. The operator pushes the two pressure bars 47 upwards and repeats this process until the two ends of the tomato harvester conveyor belt can be connected. After the operator completes the connection of the locking mechanism 3 at both ends of the tomato harvester conveyor belt, the operator pulls the pull ring 443 on the check pawl 44 to pull the check pawl 44 to release the force on the ratchet 43, release the rotating roller 42, and the rotating roller 42 rotates back to release the tightening rope 45. When disassembling the tomato harvester conveyor belt, one end of the tightening rope 45 is connected to the rotating roller 42, and the other end passes through both ends of the tomato harvester conveyor belt and connects to the hook 46. The pressure bar 47 is slid to its longest position to the left of the rotating roller 42. The operator pushes the two pressure bars 47 upwards, causing the rotating roller 42 to rotate clockwise by a certain angle. Simultaneously, the rotating roller 42 drives the two ratchet wheels 43 to rotate clockwise by a certain angle. The check pawl 44 slides on the back of the teeth of the ratchet wheels 43. As the rotating roller 42 rotates, the tightening rope 45 wraps around it, causing the belt crossbars 2 at both ends to continuously move closer together. At this point, the tension at the connection points of the two ends of the tomato harvester conveyor belt disappears, facilitating the operator's disassembly of the locking mechanism 3. Optionally, the elastic element 442 is a torsion spring or a tension spring.

[0032] like Figure 2 As shown, in this embodiment, the opening of the hook 46 is provided with a snap fastener 461 to prevent the tightening rope 45 from slipping off, ensuring that the tightening rope 45 can smoothly tension both ends of the tomato harvester conveyor belt.

[0033] like Figure 2As shown, in this embodiment, the hook 46 and the U-shaped frame 41 are detachably connected, resulting in a simple structure and convenient assembly / disassembly. This allows for targeted replacement of either the hook 46 or the U-shaped frame 41, improving component utilization and reducing operating costs. Optionally, the hook 46 and the U-shaped frame 41 are connected by threads, further simplifying the structure and facilitating assembly / disassembly. Optionally, the hook 46 is provided with a connecting sleeve 462, and the U-shaped frame 41 is provided with a connecting screw 411. The connecting sleeve 462 and the connecting screw 411 are screwed together, enabling the hook to withstand larger loads.

[0034] like Figure 1 and Figure 4 As shown, in this embodiment, the locking mechanism 3 includes a first belt buckle 31 disposed on the first end of the belt 1, a second belt buckle 32 disposed on the second end of the belt 1, and a locking connecting crossbar 33 for connecting the first belt buckle 31 and the second belt buckle 32; by tightening the two ends of the tomato harvester conveyor belt with the tightening rope 45, the first belt buckle 31 and the second belt buckle 32 are aligned, and the locking connecting crossbar 33 passes through the first belt buckle 31 and the second belt buckle 32 to complete the connection between the two ends of the tomato harvester conveyor belt. Optionally, the first belt buckle 31 is provided with a connecting bolt 311 and a waist-shaped hole 312. The connecting bolt 311 passes through the waist-shaped hole 312 and is connected to the first end of the belt 1, so that the first belt buckle 31 can adjust its relative position with the first end of the belt 1. The structure of the second belt buckle 32 is the same as that of the first belt buckle 31. The connecting bolt 311 on the second belt buckle 32 passes through the waist-shaped hole 312 and is connected to the second end of the belt 1, so that the second belt buckle 32 can adjust its relative position with the second end of the belt 1, thereby ensuring that the first belt buckle 31 and the second belt buckle 32 can be aligned, so that the buckle connecting crossbar 33 can pass smoothly through the first belt buckle 31 and the second belt buckle 32.

[0035] like Figure 4 As shown, in this embodiment, the first belt buckle 31 and the second belt buckle 32 are respectively provided with an outer retaining seat 34 and an intermediate retaining seat 35. The outer retaining seat 34 is provided with an outer bushing 36, and the intermediate retaining seat 35 is provided with an intermediate bushing 37. The buckle connecting crossbar 33 passes through the outer bushing 36 and the intermediate bushing 37 to connect the first belt buckle 31 and the second belt buckle 32. The first belt buckle 31 is provided with an outer retaining seat 34 and an intermediate retaining seat 35 spaced apart, and the second belt buckle 32 is provided with an outer retaining seat 34 spaced apart. During assembly, the first belt buckle 31 and the second belt buckle 32 are connected. The intermediate buckle 35 on the first belt buckle 31 and the intermediate buckle 35 on the second belt buckle 32 are located between the outer buckle 34 on the first belt buckle 31 and the outer buckle 34 on the second belt buckle 32. The axis lines of the two outer bushings 36 and the two intermediate bushings 37 coincide. The buckle connecting crossbar 33 passes through the two outer bushings 36 and the two intermediate bushings 37 to connect the two ends of the tomato harvester conveyor belt.

[0036] like Figure 5 As shown, in this embodiment, the first end of the outer bushing 36 is provided with a flange 361, and the second end is provided with a chamfered flange 362. The outer bushing 36 has two slots 363 that communicate with the chamfered flange 362. When installing the outer bushing 36, the chamfered flange 362 is pressed into the outer retainer 34. After the chamfered flange 362 springs up, it engages with the flange 361 to secure the outer retainer 34, ensuring a reliable connection and preventing the outer bushing 36 from loosening. The outer bushings 36 at both ends limit the movement space of the middle bushing 37. Ensure that the intermediate bushing 37 will not fall off axially; when disassembling or replacing the outer bushing 36, the outer bushing 36 can be removed by squeezing the chamfered flange 362 with snap ring pliers. The worn outer bushing 36 replaces the wear of the first belt buckle 31 (second belt buckle 32). During maintenance, only the belt buckle outer bushing 36 needs to be replaced, which can reduce costs and extend the service life of the first belt buckle 31 (second belt buckle 32). It is understood that the number of slots 363 can also be three or four, as long as the chamfered flange 362 can be deformed under pressure.

[0037] like Figure 5 As shown, in this embodiment, the chamfered flange 362 is provided with positioning structures 364 for easy clamping. Two positioning structures 364 are symmetrically arranged on both sides of the slot 363. When disassembling or replacing the outer bushing 36, the two positioning structures 364 on the chamfered flange 362 of the outer bushing 36 can be clamped with snap ring pliers to compress the outer bushing 36. The two slots 363 cause the compressed outer bushing 36 to deform, thus removing the outer bushing 36. Optionally, the positioning structure 364 is a blind hole, a through hole, or a groove to facilitate clamping with snap ring pliers.

[0038] like Figure 1 and Figure 4As shown, in this embodiment, the locking connecting crossbar 33 is provided with shoulders 331 for defining the position of the locking connecting crossbar 33 in its axial direction. Shoulders 331 are respectively provided on both ends of the locking connecting crossbar 33. The outer diameter of the shoulders 331 is adapted to the inner diameter of the outer bushing 36 and the intermediate bushing 37. During assembly, the locking connecting crossbar 33 is inserted into the locking mechanism 3 on the first belt 1 from the outside of the tomato harvester conveyor belt. After the first shoulder 331 on the locking connecting crossbar 33 passes through the locking mechanism 3 on the first belt 1, the locking connecting crossbar 33 continues to be inserted into the locking mechanism 3 on the second belt 1 until the second shoulder 331 on the locking connecting crossbar 33 passes through the locking mechanism 3 on the first belt 1. At this time, the locking connection is released. Due to the weight of the crossbar 33 itself and the tension of the tomato harvester conveyor belt, the shoulder 331 of the crossbar 33 and the outer bushing 36 on the locking mechanism 3 will be misaligned, thus preventing the crossbar 33 from moving axially. During disassembly, the two ends of the tomato harvester conveyor belt are tensioned by the tightening rope 45, and the crossbar 33 is lifted. The crossbar 33 can be pulled out by keeping the axes of the crossbar 33, the outer bushing 36, and the intermediate bracket 35 aligned. Its structure is simple and easy to disassemble and assemble. Compared with the existing method of preventing axial movement by spot welding of bushings or fixing with bolts, no additional disassembly and assembly tools are required, which can greatly improve the efficiency of disassembly and assembly. It is suitable for tomato harvester conveyor belts with high disassembly and assembly frequency.

[0039] In this embodiment, the locking connecting crossbar 33 is provided with shoulders 331 for defining the position of the locking connecting crossbar 33 in its axial direction. Shoulders 331 are respectively provided on both ends of the locking connecting crossbar 33. The outer diameter of the shoulders 331 is larger than the inner diameter of the outer bushing 36 and the intermediate bushing 37. The shoulders 331 are screwed to the locking connecting crossbar 33 and can move along the axial direction of the locking connecting crossbar 33. During assembly, the shoulders 331 are first rotated to move the shoulders 331 on the locking connecting crossbar 33 towards the center. Then, the first end of the locking connecting crossbar 33 is inserted between the two belts 1 into the outer bushing 36 and the intermediate bushing 37 on the first belt 1. After the shoulder 331 abuts against the outer bushing 36, the second end of the locking connecting crossbar 33 is inserted between the two belts 1 into the outer bushing 36 and the middle bushing 37 on the second belt 1. Rotating the shoulder 331 causes the two shoulders 331 to abut against the outer bushings 36 on the two belts 1 respectively, thereby preventing the locking connecting crossbar 33 from moving axially. When disassembling, rotating the shoulder 331 on the first end of the locking connecting crossbar 33 causes the second end of the locking connecting crossbar 33 to be pulled out from the locking mechanism 3 on the belt 1. Deflecting the locking connecting crossbar 33 causes the first end of the locking connecting crossbar 33 to be pulled out from the locking mechanism 3 on the other belt 1. Its structure is simple, easy to disassemble and assemble, and can greatly improve the efficiency of disassembly and assembly.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
