Description

Technical Field

[0001] This utility model relates to the field of straw baling technology, specifically a straw compression and baling device. Background Technology

[0002] Straw refers to the stems and leaves remaining after the rice, wheat, corn, and other gramineous crops have matured and been threshed. With the widespread use of coal, electricity, and natural gas, and the abundance of various industrial products, the demand for straw in rural areas has decreased. In recent years, with the continuous progress of science and technology and the increasing awareness of environmental protection, straw has gradually been utilized by people, for example, as feed or compressed into a solid biomass fuel that can be directly burned. When recycling straw, it is generally compressed into blocks to facilitate transportation, reduce space occupation, and facilitate subsequent processing.

[0003] The authorized publication number CN221653212U discloses a crop straw baling device, including a working box. The working box includes a cutting chamber located at the entrance of the working box, a crushing chamber connected to the cutting chamber, and a compression chamber connected to the crushing chamber. The cutting chamber is equipped with a cutting component for cutting the straw entering the cutting chamber. The crushing chamber is equipped with a crushing component for crushing the cut straw. The straw is cut into small pieces by the cutting component and then falls into the crushing chamber for further crushing, thereby improving crushing efficiency. The crushed straw falls into the compression chamber and is compressed into a tightly bound block, reducing the space occupied and facilitating storage, transportation, and use.

[0004] However, in the existing technology, the straw is in a loose state during the crushing process. After the straw is crushed and falls into the compression chamber, the straw piled up inside the compression chamber is relatively loose, which results in smaller blocks when compressed into blocks. This requires multiple compressions, which reduces the efficiency of straw baling. Therefore, there is an urgent need for a straw compression and baling device. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model proposes a straw compression and baling device to solve the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A straw compression and baling device includes a processing box, and a compression box is fixedly connected to one side of the bottom end of the processing box;

[0008] The processing box has two rotatably connected internally, each of which has multiple crushing blades on its surface. The front of each of the two crushing shafts is fixedly connected to a first gear that meshes with each other. A first servo motor is mounted on the front of the processing box. The processing box also has two rotatably connected internally, each of which has a second gear that meshes with each other fixedly connected on its front. A second servo motor is mounted on the front of the processing box.

[0009] Preferably, a feed inlet is provided at the right end of the top of the processing box, and guide plates are provided on the left and right inner walls of the processing box, with the guide plates located above the pressure roller.

[0010] Preferably, the output end of the first servo motor is fixedly connected to one of the crushing shafts, and the output end of the second servo motor is fixedly connected to one of the pressure rollers.

[0011] Preferably, a cylinder is installed on the top of the compression chamber, and the output end of the cylinder passes through the compression chamber and is fixedly connected to a pressure plate.

[0012] Preferably, a bracket is fixedly connected to the outside of the compression box, and support legs are fixedly connected to both ends of the bracket.

[0013] Preferably, the front of the compression box has a slot, a baffle is inserted into the slot, and a rack is fixedly connected to the bottom of the baffle.

[0014] Preferably, a third servo motor is installed at the bottom of the compression box, and a third gear is fixedly connected to the output end of the third servo motor, which meshes with a rack.

[0015] Compared with the prior art, the beneficial effects of this utility model's straw compression and baling device are:

[0016] First, through the synergistic action of the crushing shaft and the pressure roller, the straw is immediately compacted by the pressure roller after crushing, which effectively reduces the bulkiness of the material. This solves the problem of loose accumulation caused by the straw falling directly into the compression chamber after crushing in the existing technology, which greatly increases the density of straw in the compression chamber. A single compression can form larger and denser blocks of straw, reducing the number of compressions and improving the overall baling efficiency.

[0017] Secondly, the bottom of the compression chamber uses a third servo motor-driven gear and rack mechanism to precisely control the opening and closing of the baffle. After compression, the baffle automatically opens to discharge the straw blocks, and automatically resets after discharge. The entire process requires no manual intervention, which not only avoids the safety risks of manual operation, but also ensures a seamless connection between the compression and discharge processes.

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] For a straw compression and baling device according to this specific embodiment, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a processing box 1, and a compression box 2 is fixedly connected to one side of the bottom end of the processing box 1;

[0025] The processing box 1 has two rotatably connected crushing shafts 11 inside. Each crushing shaft 11 has multiple crushing blades 12 on its surface. The front of each crushing shaft 11 is fixedly connected to a first gear 13 that meshes with each other. A first servo motor 14 is installed on the front of the processing box 1. The processing box 1 also has two rotatably connected pressure rollers 15 inside. The front of each pressure roller 15 is fixedly connected to a second gear 16 that meshes with each other. A second servo motor 17 is installed on the front of the processing box 1.

[0026] Through the above technical solution, the processing box 1 serves as the main container for straw processing. One side of its bottom is connected to the compression box 2. Inside the processing box 1, two parallel crushing shafts 11 are provided with crushing blades 12 on their surfaces for crushing straw. The crushing shafts 11 are driven by a first servo motor 14 through meshing with a first gear 13 to achieve reverse rotation to cut the straw. The two pressure rollers 15 of the processing box 1 are driven by a second servo motor 17 through meshing with a second gear 16 for preliminary compaction of the crushed straw. Through the synergistic action of the crushing shafts 11 and the pressure rollers 15, the crushing and preliminary compression of the straw are achieved, greatly reducing the looseness of the crushed straw.

[0027] A feed inlet is provided at the right end of the top of the processing box 1, and guide plates 18 are provided on the left and right inner walls of the processing box 1. The guide plates 18 are located above the pressure roller 15.

[0028] With the above technical solution, the feed inlet is located at the top right end of the processing box 1 and is used to feed in straw raw materials. The guide plate 18 is set on the inner wall of the processing box 1 and is located above the pressure roller 15. Its function is to guide the crushed straw evenly to the area of ​​the pressure roller 15, avoid material accumulation or deviation, optimize the material flow path, and improve processing efficiency.

[0029] The output end of the first servo motor 14 is fixedly connected to one of the crushing shafts 11, and the output end of the second servo motor 17 is fixedly connected to one of the pressure rollers 15.

[0030] Through the above technical solution, the first servo motor 14 directly drives one of the crushing shafts 11, and drives the other crushing shaft 11 to rotate in the opposite direction through the first gear 13, thereby realizing straw cutting. The second servo motor 17 directly drives one of the pressure rollers 15, and drives the other pressure roller 15 to rotate in the opposite direction through the second gear 16, thereby realizing straw compaction or conveying. The servo motor provides precise control to ensure that the crushing and pressure roller actions are synchronized.

[0031] A cylinder 21 is installed on the top of the compression box 2. The output end of the cylinder 21 passes through the compression box 2 and is fixedly connected to a pressure plate 22.

[0032] With the above technical solution, cylinder 21 is installed on the top of compression box 2, and the output end is connected to pressure plate 22. Cylinder 21 drives pressure plate 22 to press down, compressing straw into high-density blocks. The size of pressure plate 22 matches the inner cavity of compression box 2 to ensure uniform distribution of compression force.

[0033] A bracket 23 is fixedly connected to the outside of the compression box 2, and support legs 24 are fixedly connected to both ends of the bracket 23.

[0034] Through the above technical solution, the bracket 23 is fixed on the outside of the compression box 2, and the two ends are connected to the support legs 24 to form a stable three-dimensional support frame, ensuring the overall stability of the device and preventing it from tipping over during compression.

[0035] The front of the compression box 2 has a slot, into which a baffle 25 is inserted. A rack 26 is fixedly connected to the bottom of the baffle 25.

[0036] With the above technical solution, a slot is opened on the front of the compression box 2, the baffle 25 is inserted into the slot, and the rack 26 is fixed at the bottom. The baffle 25 closes the outlet of the compression box 2 during compression, and opens by moving the rack 26 after compression to release the straw blocks.

[0037] A third servo motor 27 is installed at the bottom of the compression box 2. A third gear 28 is fixedly connected to the output end of the third servo motor 27. The third gear 28 meshes with the rack 26.

[0038] Through the above technical solution, the third servo motor 27 is installed at the bottom of the compression box 2, and the output end is connected to the third gear 28. The third gear 28 meshes with the rack 26 at the bottom of the baffle 25. The third servo motor 27 drives the gear in both forward and reverse directions, thereby moving the rack 26 and the baffle 25 to achieve automatic opening and closing.

[0039] Its working principle is as follows: Straw raw material is fed into the feed port at the top right end of the processing box 1. After the straw enters the processing box, the first servo motor 14 starts and drives one of the crushing shafts 11 to rotate. Through the meshing of the first gear 13, it drives the other crushing shaft 11 to rotate in the opposite direction. The crushing blades 12 on the surface of the two crushing shafts 11 rotate in the opposite direction, cutting the straw into small pieces or fragments. The crushed straw is guided between the two pressure rollers by the guide plate 18. The second servo motor 17 starts and drives one of the pressure rollers 15 to rotate. Through the meshing of the second gear 16, it drives the other pressure roller 15 to rotate in the opposite direction. The pressure roller 15 crushes the straw into small pieces or fragments. The crushed straw is further compacted and conveyed downwards to the connecting port at the bottom of the processing box 1, entering the compression box 2. The cylinder 21 at the top of the compression box 2 is activated, pushing the pressure plate 22 down to compress the straw with high intensity, forming high-density blocks. After compression, the third servo motor 27 drives the third gear 28 to rotate, which drives the baffle 25 to move along the slot through the meshing rack 26, opening the outlet of the compression box 2. The compressed straw blocks are discharged from the outlet of the compression box 2, completing the baling. After discharge, the third servo motor 27 reverses, the baffle 25 resets, the compression box 2 is closed, and the next compression cycle begins.

[0040] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
