Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw technology, and in particular to a straw cutting device for processing straw. Background Technology
[0002] Straw usually refers to the remaining part of crops after harvesting the grains. More than half of the products of crop photosynthesis are found in straw. Straw is rich in elements such as nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. Therefore, returning straw to the field can increase soil organic matter, improve soil structure and enhance soil fertility.
[0003] In the industrial chain of straw resource utilization, the cutting process is a key upstream link. Most traditional cutting equipment can only cut straw into small straws of a fixed length. When it is necessary to cut straw into small straws of different lengths, other cutting equipment is required to cut the small straws again, which is extremely inconvenient. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figure 1-7 A straw processing cutting device includes a base plate 1, eight knife grooves 101 on the base plate 1, connecting columns 2 fixedly installed at the four corners of the top of the base plate 1, a top plate 3 fixedly installed on the top of the connecting columns 2, a cylinder 4 fixedly installed on the top plate 3, a support frame 5 driven by the cylinder 4, a motor 6 fixedly installed on the outside of the support frame 5, a rotating shaft 61 driven by the motor 6, four cutting blades 7 movably arranged on the rotating shaft 61, and eight sets of threaded holes 611 on the rotating shaft 61.
[0027] Two mounting blocks 71 are fixedly installed on both sides of the cutting blade 7. The mounting blocks 71 are attached to the outer wall of the rotating shaft 61. A bolt 11 passes through the mounting block 71 and is threaded into the threaded hole 611.
[0028] Meanwhile, bearings 9 are embedded in both sides of the inner wall of the support frame 5, and sliding sleeves 51 are fixedly installed at the four corners of the support frame 5. The sliding sleeves 51 are slidably sleeved on the connecting column 2, and the sliding sleeves 51 make the movement of the support frame 5 more stable.
[0029] Furthermore, the two ends of the rotating shaft 61 are connected to two bearings 9 respectively. When the rotating shaft 61 rotates, the bearings 9 will not cause the support frame 5 to rotate.
[0030] Meanwhile, limiting components 8 are fixedly installed on both sides of the inner wall of the support frame 5. The limiting components 8 are used to compress the straw.
[0031] Furthermore, the limiting component 8 includes two fixing rods 81, which are fixedly installed on one side of the inner wall of the support frame 5.
[0032] Meanwhile, the fixed rod 81 is hollow, and a spring 83 is installed inside the cavity. The top of the spring 83 is fixedly connected to the top of the cavity. A movable rod 82 is slidably inserted into the cavity of the fixed rod 81. The top of the movable rod 82 is fixedly connected to the bottom of the spring 83. The elastic force of the spring 83 acts on the pressure plate 84, which makes it easier for the pressure plate 84 to press the straw.
[0033] Meanwhile, pressure plates 84 are fixedly installed at the bottom of the two movable rods 82. The pressure plates 84 press the straw tightly, making it easier for the cutting blade 7 to cut it.
[0034] Furthermore, a motor protective shell 10 is provided outside the motor 6 to protect the motor 6.
[0035] In this embodiment, the straw is placed on the base plate 1, and then the motor 6 is started to drive the rotating shaft 61 to rotate at high speed, which in turn drives the four cutting blades 7 to rotate at high speed synchronously. Then the cylinder 4 is started, and the cylinder 4 drives the support frame 5 to move downward, which in turn drives the limiting component 8 to move downward synchronously. The pressure plate 84 contacts the straw. At this time, the cylinder 4 continues to drive the support frame 5 to move downward. At this time, the fixing rod 81 moves downward and squeezes the spring 83. The straw is firmly pressed by the pressure plate 84. The cutting blades 7 rotate at high speed to cut the straw. After the cutting is completed, the motor 6 stops working. Then the cylinder 4 drives the support frame 5 to move upward. At this time, the spring 83 slowly returns to its original position. The cylinder 4 drives the support frame 5 to return to its original position, which is convenient for the next cutting.
[0036] When it is necessary to adjust the length of the cut straw, tighten the bolt 11 to remove it from the threaded hole 611. Then adjust the position of the cutting blade 7 on the rotating shaft 61. When it is adjusted to the appropriate position, pass the bolt 11 through the mounting block 71 and thread it into another threaded hole 611 and tighten it. At this time, the straw can be cut into small straws of different lengths.
[0037] In this invention, the bolt 11 is loosened and removed, the position of the cutting blade 7 on the rotating shaft 61 is adjusted, and then the bolt 11 is threaded through the mounting block 71 and inserted into the threaded hole 611 and tightened. At this time, the straw can be cut into small straws of different lengths without the need for other cutting equipment to cut again. It is more flexible and conducive to cutting straw into small straws of different lengths.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
