Description

Technical Field

[0001] The utility model belongs to the technical field related to unloading buffering, and particularly relates to a sliding buffering device for a grass baler. Background Art

[0002] A hay baler is a mechanical device specially used to pack and compress scattered hay. After the hay is cut into shorter lengths by a lawn mower, it passes through the baler's compression device to compress the hay into hay blocks of a certain density. The hay blocks are then bundled together using the baler's rope device to form a solid package, and the packed hay blocks are transported to the corresponding locations.

[0003] The common method of transporting hay blocks is to place the hay blocks on a transmission device and use the cyclic motion of the transmission device to drive the hay blocks for transport. However, in actual use, the hay blocks are easily deviated from the transmission device or even separated from the transmission device due to external forces during transport. When transported to the end of the transmission device, the impact force generated by the transmission can easily damage the packaged hay blocks. To this end, we provide a sliding buffer device for hay balers to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0027] See also Figure 1-7 The utility model is a sliding buffer device for a forage baler, comprising a discharge conveying assembly 1, a limit clamping assembly 2 and two symmetrically arranged buffer assemblies 3. Specifically, the discharge conveying assembly 1 comprises a plurality of rotatably arranged transmission rollers 101, and the packaged forage blocks are placed on the transmission rollers 101. The transmission rollers 101 rotate to drive the forage blocks to move synchronously for transportation.

[0028] Furthermore, the limit clamping assembly 2 is slidably matched with the unloading conveying assembly 1. The limit clamping assembly 2 includes two clamping plates 201 that are symmetrically slidably arranged. The forage block is placed between the two clamping plates 201. The two clamping plates 201 approach each other to clamp the forage block. At the same time, the limit clamping assembly 2 moves synchronously with the forage block. The forage block is placed on the transmission roller 101. The transmission roller 101 rotates to drive the forage block to move, and the limit clamping assembly 2 moves synchronously; the buffer assembly 3 is fixedly connected to one side of the limit clamping assembly 2, and the buffer assembly 3 moves synchronously with the limit clamping assembly 2. The buffer assembly 3 includes a slidably arranged buffer transmission block 301 and a buffer adjustment block 302 that moves up and down. The buffer transmission block 301 moves synchronously with the limit clamping assembly 2. When it contacts an obstacle, the buffer transmission block 301 moves horizontally and drives the buffer adjustment block 302 to move up and down for buffering.

[0029] The operation process of this embodiment is as follows: placing the packaged grass block on the transmission roller 101, controlling the two clamping plates 201 to slide synchronously and approach each other until the clamping plates 201 are in close contact with the side of the grass block, and then limiting the position of the grass block in turn, and then controlling the rotation of the transmission roller 101 to drive the grass block to be continuously transported, and the limit clamping assembly 2 and the buffer assembly 3 move synchronously. When the grass block is transported to the end of the unloading conveying assembly 1, the buffer transmission block 301 first contacts the obstacle, and the buffer transmission block 301 moves horizontally in the opposite direction, thereby driving the buffer adjustment block 302 to move up and down, so as to prevent the grass block from directly contacting the obstacle to achieve buffering. Specific embodiment 2

[0031] See also Figure 1-7 On the basis of the specific embodiment 1, specifically, the unloading conveying assembly 1 also includes two symmetrically arranged support frames 102, the transmission roller 101 is rotatably arranged between the two support frames 102, and the lower surface of the support frame 102 is fixedly connected with a support column 103; the upper surface of the support frame 102 is fixedly connected with a vertical support plate 104, and a blocking plate 105 is fixedly connected between the two support frames 102. The blocking plate 105 limits the movement of the grass block to facilitate subsequent operations on the grass block, and a limiting slide bar 106 is fixedly connected between the vertical support plate 104 and the blocking plate 105.

[0032] Furthermore, a transmission roller 101 passes through one end of the support frame 102 and is fixedly connected to a transmission gear 107. An adjusting gear 108 is rotatably connected inside the support frame 102. The adjusting gear 108 is rotatably set between the two transmission gears 107, and the adjusting gear 108 and the transmission gear 107 are meshed with each other. Under the action of the adjusting gear 108, the two adjacent transmission gears 107 can rotate synchronously in the same direction, thereby driving the transmission roller 101 to rotate synchronously. A first driving motor is fixedly installed inside one of the support frames 102, and the output shaft of the first driving motor is fixedly connected to the corresponding transmission roller 101.

[0033] Furthermore, the limit clamping assembly 2 includes a U-shaped support plate 202 slidably arranged between two limit slide bars 106, a transmission disc 203 is rotatably connected to the top of the U-shaped support plate 202, a transmission slide groove 204 is symmetrically opened at the top of the U-shaped support plate 202, and the clamping plate 201 is slidably arranged inside the corresponding transmission slide groove 204; a second drive motor 205 is fixedly installed on the upper surface of the U-shaped support plate 202, and the output shaft of the second drive motor 205 is fixedly connected to the transmission disc 203, and a transmission connecting rod 206 is rotatably connected to the lower surface of the transmission disc 203, and the transmission connecting rod 206 is rotatably connected to the corresponding clamping plate 201, and when the transmission disc 203 rotates, the two transmission connecting rods 206 are synchronously pulled, and the corresponding clamping plate 201 is driven to move horizontally by the transmission connecting rod 206.

[0034] The operation process of this embodiment is: the grass block is placed on the transmission roller 101, and the grass block is clamped and fixed by the clamping plate 201. The specific operation process is as follows:

[0035] The second driving motor 205 is started to drive the transmission disc 203 to rotate. During this process, the transmission disc 203 pulls the two transmission connecting rods 206. The transmission connecting rods 206 rotate and simultaneously pull the corresponding clamping plates 201 to move horizontally, so that the two clamping plates 201 slide along the corresponding transmission slide grooves 204 and approach each other until they are tightly attached to the side of the forage block, thereby achieving position limitation of the forage block.

[0036] Start the first driving motor to drive the corresponding transmission roller 101 to rotate, and the transmission gear 107 on the transmission roller 101 rotates synchronously. At the same time, under the meshing action of the transmission gear 107 and the adjacent adjusting gear 108, the adjacent adjusting gears 108 rotate synchronously in the opposite direction. Under the meshing action of the adjusting gear 108 and the next transmission gear 107, the next transmission gear 107 rotates synchronously, driving the corresponding transmission roller 101 to rotate, thereby realizing the synchronous and same-direction rotation of the transmission gear 107, and then driving the transmission roller 101 to rotate synchronously in the same direction, so that the grass block is transported along the transmission roller 101. In this process, the grass block drives the limit clamping assembly 2 to move synchronously, so that the U-shaped support plate 202 moves axially horizontally along the side surface of the limit slide bar 106. Specific embodiment three

[0038] See also Figure 1-7 On the basis of the specific embodiment 1 and the specific embodiment 2, specifically, the buffer assembly 3 also includes a hollow support block 303 fixedly connected to one side of the U-shaped support plate 202, the buffer transmission block 301 slides through the hollow support block 303, and a V-shaped slide groove 304 is provided on the surface of the buffer transmission block 301 (that is, a downward inclined slide groove at one end is connected to an upward inclined slide groove at one end).

[0039] Furthermore, the buffer adjustment block 302 is arranged inside the hollow support block 303, and a transmission column 305 that slides with the V-shaped groove 304 is fixedly connected to the side of the buffer adjustment block 302 close to the buffer transmission block 301. When the buffer transmission block 301 moves horizontally, the transmission column 305 slides along the inside of the V-shaped groove 304, and the transmission column 305 moves up and down and drives the buffer adjustment block 302 to move up and down synchronously. An elastic buffer element 306 is fixedly connected between the buffer adjustment block 302 and the top and bottom of the hollow support block 303.

[0040] The operation process of this embodiment is as follows: the buffer component 3 moves synchronously with the limit clamping component 2. When the buffer transmission block 301 contacts the blocking plate 105, the grass block continues to move, so that the buffer transmission block 301 is squeezed and moves horizontally in the opposite direction (opposite to the movement direction of the grass). In this process, under the sliding cooperation of the transmission column 305 and the V-shaped slide groove 304, the transmission column 305 gradually moves upward along the V-shaped slide groove 304, thereby driving the buffer adjustment block 302 to move upward synchronously, so that the buffer adjustment block 302 squeezes the upper elastic buffer element 306 and stretches the lower elastic buffer element 306 respectively, thereby achieving buffering of the grass block and preventing the straight grass block from directly contacting the blocking plate 105 and being damaged.
