[0007] In view of this, the existing structure and defects are studied and improved, and a branch conveying equipment for forestry engineering is provided, in order to achieve the purpose of having more practical value. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a branch conveying equipment for forestry engineering to solve the above problems.

At the bottom, the lower ends of the two conveying brackets are fixedly installed with a stand, the side ends of the two stand are fixedly installed with mounting parts, and the side ends of the two mounting parts are penetrated with mounting grooves, the output end of the motor is fixedly installed with a third telescopic rod, the transmission shaft is fixedly installed on the side ends of the third telescopic rod, two first springs are fixedly installed between the positioning rod and the pressure plate, two first telescopic rods are also fixedly installed between the positioning rod and the pressure plate, the two first telescopic rods are both located on the inner side wall of the first spring, a first annular groove is opened at the circumferential end of the transmission shaft, and a second annular groove is also opened at the circumferential end of the transmission shaft, toothed rollers are fixedly installed at the circumferential ends of the two transmission rollers, the two toothed rollers are meshed with the inner toothed belt, and the circumferential end of the inner toothed belt is provided with a transmission chain plate, the rotating shaft penetrates and is rotatably installed on the inner side walls of the two mounting grooves, a synchronous belt is sleeved between the rotating shaft and the transmission roller, and a plurality of cross bars are fixedly installed in an array at the circumferential end of the rotating shaft, and a plurality of pressure blocks are provided at the side ends of each of the cross bars.

[0010] Preferably, a second spring is fixedly installed between each of the pressing blocks and the cross bar, and a second telescopic rod is also fixedly installed between each of the pressing blocks and the cross bar.

[0011] Preferably, each of the second springs is located on the inner side wall of the second telescopic rod, and a cleaning brush is fixedly mounted on the side end of each of the pressing blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, by providing a transmission gear and a driven gear to cooperate with each other, when the transmission gear and the driven gear are meshed, the speed range of the transmission chain plate driven to rotate after the motor is started is smooth. When the density of branches is large and the volume is large, the smooth transportation can allow the branches to have more sufficient time to arrange and move on the conveyor belt, reduce mutual interference between branches, effectively avoid the occurrence of blockage and material jamming, and ensure the smoothness of the conveying process. At the same time, slow transportation can make the movement state of the branches more stable, reduce the possibility of branches falling and splashing, and improve the safety of the working environment.

[0014] In the present invention, by cooperating with a speed-increasing gear and a driven gear, when the speed-increasing gear and the driven gear are meshed, the motor drives the transmission chain plate to rotate at a faster speed after starting. When the density of branches is small and the volume is small, more batches of branches can be transported per unit time by adopting fast transportation, and the idle time of equipment can be reduced, thereby improving the working efficiency of the entire branch conveying system, enabling subsequent processing links to obtain sufficient materials in time, avoiding process interruptions caused by untimely material supply, and optimizing the connection of the entire branch processing process.

[0015] In the present invention, a transmission chain plate with adjustable transport speed is provided. In the actual branch transportation scenario, the density and volume of the branches will constantly change. The adjustable transport speed of the transmission chain plate enables the device to flexibly switch between slow and fast speeds according to the real-time material conditions, and always maintain the best transportation state. Whether facing a large number of concentrated branches or a small number of scattered branches, the transportation task can be completed efficiently and stably, thereby improving the versatility and adaptability of the equipment.

[0016] In the present invention, by cooperating with a rotating shaft, a cross bar and a cleaning brush, when the transmission chain plate reciprocates to transport branches, the rotating shaft will drive each cleaning brush to rotate in the opposite direction of the transmission chain plate to clean the transmission chain plate, forming a relative motion speed difference between the two. This speed difference can generate a greater friction force, thereby more effectively scraping off dirt, leaves, wood chips and other debris attached to the surface of the transmission chain plate, thereby timely removing the debris, effectively reducing the wear between impurities and equipment, and avoiding blockage caused by accumulation of impurities.

[0017] In the present invention, by cooperating with a driven gear, a synchronous belt and a rotating shaft, the rotation speed of the cleaning brush on the rotating shaft is kept consistent with the transmission chain plate while the rotation speed of the transmission chain plate is adjusted. The time the cleaning brush stays at each position on the surface of the transmission chain plate is relatively uniform, so the chain plate can be cleaned comprehensively and evenly, avoiding the situation where some areas are over-cleaned and some areas are not cleaned properly, and ensuring that the entire surface of the transmission chain plate can be kept in a good cleaning state.

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1-Figure 8The present invention provides a branch conveying device for forestry engineering, including two conveying brackets 1, a conveying mechanism for conveying branches is provided on the conveying bracket 1, an adjusting mechanism for adjusting the conveying mechanism is provided on the conveying bracket 1, a cleaning mechanism for cleaning the conveying mechanism is provided on the conveying bracket 1, and the conveying mechanism includes an inner toothed belt 5 and a transmission roller 51. In forest farms, orchards and other places, felled or pruned branches need to be transported to a designated location for subsequent processing, such as crushing, composting, papermaking, etc. Users generally use conveying equipment to transport branches. When using the device for transportation, users can put branches on the transmission chain plate 53 on the conveying bracket 1, and start the motor 21 to drive the transmission chain plate 53 on the toothed roller 52 to rotate, thereby realizing the transmission and transportation of branches;

[0029] The adjusting mechanism includes an L-shaped fixing rod 2, a positioning rod 3 and a transmission shaft 4, the cleaning mechanism includes a driven gear 6 and a rotating shaft 7, the number of the transmission rollers 51 is two, and the two transmission rollers 51 are both rotatably installed between the two conveying brackets 1, the L-shaped fixing rod 2 is fixedly installed at the side end of the conveying bracket 1, the upper end of the L-shaped fixing rod 2 is fixedly installed with a motor 21, the positioning rod 3 is fixedly installed at the upper end of the L-shaped fixing rod 2, the upper end of the positioning rod 3 is provided with a pressing plate 31, and the upper end of the pressing plate 31 is fixedly installed with an arc-shaped clamp 32, the transmission shaft 4 is located at the side end of the motor 21, and the circumferential end of the transmission shaft 4 is fixedly installed with a transmission gear 41 and a speed increasing gear 42, and the driven The gear 6 is fixedly mounted on the circumferential end of the transmission roller 51, the rotating shaft 7 is located below the inner toothed belt 5, the lower ends of the two conveying brackets 1 are fixedly mounted with a stand 11, the side ends of the two stand 11 are fixedly mounted with mounting members 12, the side ends of the two mounting members 12 are penetrated with mounting grooves 13, the output end of the motor 21 is fixedly mounted with a third telescopic rod 22, the transmission shaft 4 is fixedly mounted on the side end of the third telescopic rod 22, two first springs 33 are fixedly mounted between the positioning rod 3 and the pressure plate 31, and two first telescopic rods 34 are also fixedly mounted between the positioning rod 3 and the pressure plate 31, and the two first telescopic rods 34 are both located on the inner side wall of the first spring 33, and the transmission A first annular groove 43 is provided at the circumferential end of the shaft 4, and a second annular groove 45 is provided at the circumferential end of the transmission shaft 4. Under different working environments and requirements, the density and size of the branches transported are different. The user can adjust the transport speed of the device. When the density and volume of the branches transported are large, the transport speed is reduced to avoid overloading the conveyor belt. The user can pull the transmission shaft 4 toward the side of the motor 21. The movement of the transmission shaft 4 will compress the third telescopic rod 22. The movement of the transmission shaft 4 will simultaneously drive the speed-increasing gear 42 and the transmission gear 41 to move. When the transmission shaft 4 moves so that the first annular groove 43 and the arc-shaped clamp 32 overlap, the first spring 33 will rebound and push the pressure plate 31 to move upward, so that the arc-shaped clamping piece 32 is clamped into the inner wall of the first annular clamping groove 43. At this time, the transmission gear 41 and the driven gear 6 are meshed, and the user can start the motor 21. The motor 21 starts to drive the transmission shaft 4 to rotate, and the rotation of the transmission shaft 4 drives the transmission gear 41 to rotate. The rotation of the transmission gear 41 drives the driven gear 6 to rotate, and the rotation of the driven gear 6 drives the transmission roller 51 to rotate. The rotation of the transmission roller 51 drives the internal toothed belt 5 to rotate through the tooth roller 52, thereby realizing the rotation of the transmission chain plate 53 to transmit the branches. Because the transmission gear 41 and the driven gear 6 are of the same size, the transmission speed at this time tends to be stable, and the transportation of the explosive branches is stable;

[0030] When the density of the transported branches is small and the volume is small, the transportation speed of the branches can be appropriately increased. The user can press the pressure plate 31 to drive the arc-shaped clamping member 32 to move downward and leave the inner wall of the first annular clamping groove 43. At this time, the user can push the transmission shaft 4 to move away from the motor 21. When the transmission shaft 4 moves to drive the second annular clamping groove 45 and the arc-shaped clamping member 32 to engage, the speed-increasing gear 42 and the driven gear 6 are engaged. The first spring 33 will rebound to drive the arc-shaped clamping member 32 on the pressure plate 31 to engage in the second annular clamping groove 45. Because the diameter of the speed-increasing gear 42 is larger than that of the driven gear 6, when the motor 21 starts to drive the speed-increasing gear 42 on the transmission shaft 4 to rotate, it will drive the driven gear 6 to rotate faster, thereby causing the transmission chain plate 53 on the inner toothed belt 5 to rotate faster, thereby realizing high-speed transmission of branches.

[0031] The circumferential ends of the two transmission rollers 51 are fixedly installed with toothed rollers 52, the two toothed rollers 52 are meshed with the inner toothed belt 5, the circumferential ends of the inner toothed belt 5 are provided with transmission chain plates 53, the rotating shaft 7 passes through and is rotatably installed on the inner side walls of the two installation grooves 13, a synchronous belt 61 is sleeved between the rotating shaft 7 and the transmission rollers 51, a plurality of cross bars 71 are fixedly installed in an array at the circumferential ends of the rotating shaft 7, a plurality of pressure blocks 72 are provided at the side ends of each cross bar 71, a second spring 73 is fixedly installed between each pressure block 72 and the cross bar 71, a second telescopic rod 74 is also fixedly installed between each pressure block 72 and the cross bar 71, each second spring 73 is located on the inner side wall of the second telescopic rod 74, and a cleaning brush 7 is fixedly installed at the side ends of each pressure block 72 5. When the transmission roller 51 rotates, the rotating shaft 7 is driven to rotate through the synchronous belt 61. The rotation of the rotating shaft 7 drives each cross bar 71 on the rotating shaft 7 to rotate. The rotation of the cross bar 71 cooperates with the second spring 73 and the second telescopic rod 74 to drive each cleaning brush 75 on the pressing block 72 to rotate. The direction of rotation of each cleaning brush 75 is opposite to the direction of rotation of the transmission chain plate 53 at the bottom. When the transmission chain plate 53 reciprocates to transport the branches, it drives each cleaning brush 75 on the rotating shaft 7 to rotate in the opposite direction to clean the wood chips, leaves, etc. remaining on the transmission chain plate 53. The rotation of the rotating shaft 7 is driven by the transmission roller 51 to drive the driven gear 6 to rotate, so that the rotation speed of the rotating shaft 7 is consistent with that of the transmission roller 51.

[0032] Working principle:

[0033] In the first step, in forest farms, orchards and other places, the cut or pruned branches need to be transported to a designated location for subsequent processing, such as crushing, composting, papermaking, etc. Users generally use conveying equipment to transport the branches. When using the device for transportation, the user can put the branches on the transmission chain plate 53 on the conveying bracket 1, and by starting the motor 21, the transmission chain plate 53 on the gear roller 52 is driven to rotate, thereby realizing the transmission and transportation of the branches;

[0034] In the second step, under different working environments and requirements, the density and size of the branches transported are different. The user can adjust the transport speed of the device. When the density and volume of the branches transported are large, the transport speed is reduced to avoid overloading the conveyor belt. The user can pull the transmission shaft 4 to one side of the motor 21. The movement of the transmission shaft 4 will compress the third telescopic rod 22. The movement of the transmission shaft 4 will simultaneously drive the speed increase gear 42 and the transmission gear 41 to move. When the transmission shaft 4 moves so that the first annular groove 43 and the arc-shaped clamping member 32 overlap, the first spring 33 will rebound and push the pressure plate 31 to move upward, so that The arc-shaped clamping member 32 is clamped into the inner wall of the first annular clamping groove 43. At this time, the transmission gear 41 and the driven gear 6 are meshed. The user can start the motor 21. The motor 21 starts to drive the transmission shaft 4 to rotate. The rotation of the transmission shaft 4 drives the transmission gear 41 to rotate. The rotation of the transmission gear 41 drives the driven gear 6 to rotate. The rotation of the driven gear 6 drives the transmission roller 51 to rotate. The rotation of the transmission roller 51 drives the internal toothed belt 5 to rotate through the toothed roller 52, thereby realizing the rotation of the transmission chain plate 53 to transmit the branches. Because the transmission gear 41 and the driven gear 6 are of the same size, the transmission speed at this time tends to be stable, and the transportation of the explosive branches is stable.

[0035] The device is provided with a transmission gear 41 and a driven gear 6 to cooperate. When the transmission gear 41 and the driven gear 6 are meshed, the motor 21 starts to drive the transmission chain plate 53 to rotate at a gentle speed. When the density of branches is large and the volume is large, the gentle transportation can give the branches more time to arrange and move on the conveyor belt, reduce the mutual interference between the branches, effectively avoid the occurrence of blockage and material jamming, and ensure the smoothness of the conveying process. At the same time, the slow transportation can make the movement state of the branches more stable, reduce the possibility of branches falling and splashing, and improve the safety of the working environment.

[0036] The third step is to appropriately increase the transport speed of branches when the density and volume of the branches to be transported are small. The user can press the pressure plate 31 to drive the arc-shaped clamp 32 to move downward and leave the inner wall of the first annular groove 43. At this time, the user can push the transmission shaft 4 to move away from the motor 21. When the transmission shaft 4 moves to drive the second annular groove 45 and the arc-shaped clamp 32 to engage, the speed-increasing gear 42 and the driven gear 6 are engaged. The first spring 33 will rebound to drive the arc-shaped clamp 32 on the pressure plate 31 to engage in the second annular groove 45. Because the diameter of the speed-increasing gear 42 is larger than that of the driven gear 6, when the motor 21 starts to drive the speed-increasing gear 42 on the transmission shaft 4 to rotate, it will drive the driven gear 6 to rotate faster, thereby accelerating the rotation of the transmission chain plate 53 on the inner toothed belt 5, thereby realizing high-speed transmission of branches.

[0037] The device is provided with a speed-increasing gear 42 and a driven gear 6 to cooperate. When the speed-increasing gear 42 and the driven gear 6 are meshed, the motor 21 starts and drives the transmission chain plate 53 to rotate at a faster speed. When the density of branches is small and the volume is small, more batches of branches can be transported per unit time by fast transportation, and the idle time of the equipment can be reduced, thereby improving the working efficiency of the entire branch transportation system, enabling the subsequent processing links to obtain sufficient materials in time, avoiding process interruption caused by untimely material supply, and optimizing the connection of the entire branch processing process;

[0038] The device is provided with a transmission chain plate 53 with adjustable transport speed. In the actual branch transport scene, the density and volume of the branches will constantly change. The adjustable transport speed of the transmission chain plate 53 allows the device to flexibly switch between slow and fast speeds according to the real-time material situation, and always maintain the best transport state. Whether facing a large number of concentrated branches or a small number of scattered branches, the transport task can be completed efficiently and stably, thereby improving the versatility and adaptability of the equipment.

[0039] In the fourth step, when the transmission roller 51 rotates, the synchronous belt 61 will drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 will drive each cross bar 71 on the rotating shaft 7 to rotate. The rotation of the cross bar 71 cooperates with the second spring 73 and the second telescopic rod 74 to drive each cleaning brush 75 on the pressing block 72 to rotate. The direction of rotation of each cleaning brush 75 is opposite to the direction of rotation of the transmission chain plate 53 at the bottom. When the transmission chain plate 53 reciprocates to transport the branches, it will drive each cleaning brush 75 on the rotating shaft 7 to rotate in the opposite direction to clean the wood chips, leaves, etc. remaining on the transmission chain plate 53. The rotation of the rotating shaft 7 is driven by the transmission roller 51 to drive the driven gear 6 to rotate, so that the rotation speed of the rotating shaft 7 will be consistent with that of the transmission roller 51.

[0040] The device is provided with a rotating shaft 7, a cross bar 71 and a cleaning brush 75, and when the transmission chain plate 53 reciprocates to transport branches, the rotating shaft 7 drives each cleaning brush 75 to rotate in the opposite direction of the transmission chain plate 53 to clean the transmission chain plate 53, and a relative motion speed difference is formed between the two. This speed difference can generate a greater friction force, so that the dirt, leaves, wood chips and other debris attached to the surface of the transmission chain plate 53 can be scraped off more effectively, and then the debris can be removed in time, which can effectively reduce the wear between the impurities and the equipment, and at the same time avoid the accumulation of impurities and blockage caused by;

[0041] The device cooperates with the driven gear 6, the synchronous belt 61 and the rotating shaft 7 so that the rotation speed of the driving chain plate 53 can be adjusted while the rotation speed of the cleaning brush 75 on the rotating shaft 7 is kept consistent with the driving chain plate 53. The time that the cleaning brush 75 stays at each position on the surface of the driving chain plate 53 is relatively uniform, so the chain plate can be cleaned comprehensively and evenly, avoiding the situation where some areas are over-cleaned and some areas are not cleaned properly, and ensuring that the entire surface of the driving chain plate 53 can be kept in a good cleaning state.
