Description

Technical Field

[0001] This utility model relates to the field of straw briquetting, and in particular to a straw briquetting machine. Background Technology

[0002] Straw briquetting is a technology that mechanically compresses straw into dense blocks, significantly reducing the volume of straw and making it easier to store and transport. It not only helps solve the problem of waste disposal in agricultural production, but also provides valuable resources for the agricultural and energy sectors.

[0003] Traditional straw briquetting devices can compress messy and loose straw into compact blocks during operation. The straw is then manually tied together, and finally the bundled straw blocks are pulled out to complete the straw briquetting process.

[0004] However, in actual work, workers need to bend over or even lie on the ground and use tools to pass the binding rope through the bottom of the straw block before binding and securing it. This makes the binding process of the straw block very inconvenient and affects the processing efficiency of the straw, which needs to be improved. Utility Model Content

[0031] like Figure 2 , Figure 4 As shown, a guide wheel 23 is provided on the lower part of the back side of the push frame 21. The guide wheel 23 is embedded in two of the bottom tubes 13. The guide wheel 23 is provided with guide rings 24 that clamp the two sides of the bottom tube 13 to limit the horizontal movement of the push frame 21 and prevent it from deviating during the movement.

[0032] like Figure 2 , Figure 4 As shown, a positioning wheel 25 is provided above the back side of the push frame 21. The positioning wheel 25 is equipped with a positioning ring 26 that presses the lower end face of the uppermost crossbeam of the frame 11 to limit the vertical movement of the push frame 21 and prevent jumping during the movement.

[0033] like Figure 2 As shown, the support assembly 3 includes a suspension 31 and multiple columns 32. The suspension 31 is horizontally positioned above the compaction box 1, and the columns 32 are vertically positioned at the four corners of the suspension 31 and fixed to the frame 11.

[0034] like Figure 2 As shown, the compaction component 4 includes a pressure frame 41 and a plurality of pressure tubes 42. The pressure frame 41 is horizontally arranged, and the pressure tubes 42 are horizontally arranged at intervals on the lower end face of the pressure frame 41 and are respectively aligned with each bottom tube 13.

[0035] like Figure 2 As shown, the four corners of the pressure frame 41 are rotatably connected to limit wheels 43. The two limit wheels 43 at the front and the two limit wheels 43 at the rear rotate laterally and longitudinally, respectively. The limit wheels 43 are provided with limit rings 44 that press against the side wall of the column 32 to limit the pressure frame 41 in the lateral and longitudinal directions and prevent deviation during movement.

[0036] like Figure 2 , Figure 3 , Figure 4 As shown, the binding mechanism 5 includes a support frame 51, a turntable 52, a guide tube 53, and a fixing ring 54. The support frame 51 is located at the tail end of the frame 11, and multiple turntables 52 are rotatably connected to the support frame 51.

[0037] like Figure 2 , Figure 3 , Figure 4 As shown, the turntable 52 includes a rotating tube 521, a positioning plate 522, and a movable plate 523. The rotating tube 521 is horizontally rotatably connected to the support frame 51, and the positioning plate 522 is disposed at one end of the rotating tube 521. The movable plate 523 is horizontally slidably connected to the outer wall of the rotating tube 521, and a screw 524 for pressing against the outer wall of the rotating tube 521 is threaded onto the movable plate 523.

[0038] like Figure 2 , Figure 3 , Figure 4 As shown, the guide tube 53 is horizontally disposed on the lower end face of the frame 11 and is located in the gap between the multiple bottom tubes 13. A positioning shaft 55 is horizontally rotatably connected to the trailer frame 14 for the binding rope to pass through, so as to realize the guiding and limiting of the binding rope. The fixing ring 54 is disposed at the front end of the frame 11 and is used to fix the end of the binding rope.

[0039] like Figure 2 , Figure 3 , Figure 4 As shown, a pull rod 56 is vertically arranged at the gap between multiple push tubes 22 to align with the guide tube 53, and a pull ring 57 for aligning with the guide tube 53 is provided at the lower end of the pull rod 56. A handle 58 is horizontally arranged at the upper end of the pull rod 56, and a groove 59 is provided on the push tube 22 for the handle 58 to be inserted.

[0040] like Figure 2 As shown, the unloading mechanism 6 is located at the front end of the frame 11 and is used to automatically unload the bundled grass blocks. The unloading mechanism 6 includes multiple risers 61, a rotating shaft 62, and an unloading plate 63.

[0041] like Figure 2 As shown, the risers 61 are vertically positioned at the front end of the frame 11 and are located above each bottom pipe 13. The rotating shaft 62 passes horizontally through the upper ends of multiple risers 61 and is rotatably connected to the frame 11. The unloading plate 63 is L-shaped and positioned on the rotating shaft 62, within the gap between the risers 61 and the bottom pipes 13.

[0042] When it is necessary to compress the straw, first loosen the screw 524 on the movable disc 523, then remove the movable disc 523, then install the bundled binding rope on the rotating tube 521, then install the movable disc 523 and tighten the screw 524 to install the binding rope.

[0043] Then, pull out the end of the binding rope, so that the binding rope first passes over the positioning shaft 55 on the trailer frame 14, and then passes through the guide tube 53 and the pull ring 57 at the lower end of the pull rod 56. The binding rope is then laid in the gap between the bottom tubes 13. Then, after the binding rope passes over the pivot 62 at the front position, the binding rope is embedded in the gap between the risers 61, thus securing the binding rope.

[0044] Then, the straw is filled into the compaction box 1 and the straw is filled to a certain height above the top of the compaction box 1. The hydraulic cylinder controls the pressing frame 41 and multiple pressing pipes 42 to move downward synchronously until the pressing frame 41 and multiple pressing pipes 42 completely cover the opening of the compaction box 1. Then, another hydraulic cylinder controls the push frame 21 and multiple push pipes 22 to slide forward. At this time, the push frame 21 and multiple push pipes 22 compact the straw and automatically press the straw into strip-shaped straw blocks.

[0045] Then, control the pusher 21 and multiple push tubes 22, as well as the pressure frame 41 and multiple pressure tubes 42 to reset. Then, pull the handle 58 to drive the pull rod 56 and pull ring 57 to move upward, so that the handle 58 disengages from the groove 59 on the push tube 22. Then, control the handle 58 to drive the pull rod 56 and pull ring 57 to slide forward and move along the surface of the binding rope.

[0046] When the lever 56 moves to the position of the straw block, continue to pull the handle 58 upward, so that the lever 56 and the pull ring 57 drive the binding rope upward. Then cut the binding rope and release it from the fixing ring 54, while binding the straw.

[0047] After the straw is bundled, the hydraulic cylinder controls the rotating shaft 62 and the unloading plate 63 to rotate synchronously, so that the L-shaped unloading plate 63 automatically controls the straw blocks to flip over and flip outward along the compaction box 1, realizing the automatic unloading of the straw blocks. Then, the end of the binding rope continues to pass through the pull ring 57 at the lower end of the pull rod 56 and is fixed to the fixing ring 54. The control handle 58 drives the pull rod 56 and the pull ring 57 to move backward and place them in the groove 59 on the push tube 22, completing the pressing and binding of one straw block. Then, the pressing and binding of the next straw block can be carried out.
