Abstract
Description
Technical Field
[0001] The present application relates to the technical field of straw pulping, and more specifically, to a straw pulping machine. Background Art
[0002] Straw is the general term for the stems and leaves of mature crops, typically referring to the remaining portion after the harvest of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane, and other crops. More than half of the products of crop photosynthesis are found in straw. Rich in nitrogen, phosphorus, potassium, calcium, magnesium, and organic matter, straw is a versatile, renewable bioresource. It also serves as a roughage feed, characterized by a high crude fiber content and the presence of lignin. While lignin cellulose cannot be used by pigs and chickens, it can be absorbed and utilized by ruminants such as cattle and sheep.
[0003] In the related art, water can be added to the main box of the pulping machine when in use to ensure that the straw can be pulped. In addition, the pulp must be filtered through a filter during the pulping process so that the filter residue can remain above the filter.
[0004] However, in actual use, as the filter residue continues to accumulate on the filter screen, the straw filter residue will block the filter holes of the filter screen, so that the slurry cannot enter the pulp hopper from the filter screen, thereby affecting the normal use of the pulper. Utility Model Content
[0005] In view of this, an embodiment of the present application provides a straw slurry dredging refiner to solve the problem that the refiner in the related art is prone to clogging the filter when preparing slurry.
[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:
[0007] A straw slurry dredging and refining machine, comprising:
[0008] A main box body, wherein a feeding port is provided at the top of the main box body;

[0013] The width of the frame is greater than the thickness of the cleaning brush.
[0014] In some possible implementations, the cleaning brush is used to clean the filter residue onto the frame at the opposite side thereof.
[0015] In some possible implementations, the brush handle includes a fixed portion and a movable portion;
[0016] The fixed portion is connected to the screw thread, the movable portion is connected to the bottom surface of the fixed portion through a spiral spring, and the bottom surface of the movable portion is in contact with the upper surface of the screen through the bristles.
[0017] In some possible implementations, a fastening bolt is threadedly connected to the bottom surface of the fixed portion, a nut head of the fastening bolt is connected to the first end of the coil spring, and the second end of the coil spring is connected to the top surface of the movable portion.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] like Figure 1-Figure 3 As shown, the straw slurry dredging and refining machine provided in the embodiment of the present application includes a main housing 100, a crushing shaft group, a screen 400 and a cleaning brush 500. Among them, a crushing shaft group consisting of two crushing shafts 200 is provided in the main housing 100, and a feeding port 110 is provided at the top of the main housing 100, through which the straw to be processed can be poured into the main housing 100. A driving motor 300 is fixedly provided on the outer wall of the main housing 100, and the driving shaft of the driving motor 300 is fixedly connected to the crushing shaft 200. The driving motor 300 drives the two crushing shafts 200 to rotate to process the straw in the main housing 100.
[0029] The screen 400 is arranged inside the main housing 100 and below the crushing shaft 200. The screen 400 is mainly used to filter the slurry formed after the straw is ground. In actual use, an appropriate amount of water can be added to the main housing 100 through the feed port 110 so that the water and the crushed straw form a slurry.
[0030] In this embodiment, a screw 600 is also rotatably disposed within the main housing 100. The screw 600 is located between the crushing shaft 200 and the screen 400. A servo motor 610 fixedly connected to the screw 600 is disposed outside the main housing 100. A cleaning brush 500 is threadedly connected to the screw 600. Specifically, the screw 600 is connected to the brush handle 510 of the cleaning brush 500. The bottom end of the brush handle 510 is provided with bristles 520. The bristles 520 are located on the upper surface of the screen 400 and abut against it. The two walls of the brush handle 510 along the length direction are in contact with the inner wall of the main housing 100. This allows the screw 600 to drive the cleaning brush 500 to move along the direction of the screen 400 when it rotates, thereby achieving the function of cleaning the upper surface of the screen 400.
[0031] In the straw slurry dredging and refining machine provided in the embodiment of the present application, a crushing shaft 200 and a screen 400 are provided in the main housing 100, and the screen 400 is located below the crushing shaft 200. After straw and an appropriate amount of water are put into the main housing 100 through the feeding port 110, the crushing shaft 200 can crush the straw and make it into slurry. After the slurry passes through the screen 400, the servo motor 610 is started to control the rotation of the screw 600 so that the cleaning brush 500 can brush the screen 400, thereby clearing the straw filter residue blocked on the screen 400 and sweeping this part of the straw filter residue to the edge of the screen 400. The above-mentioned structural design can prevent the straw filter residue from clogging the filter screen during the refining process, thereby effectively improving the efficiency of the refining operation.
[0032] In some embodiments, a frame 410 is provided around the outside of the screen 400. The screen 400 is fixedly connected to the inner wall of the main housing 100 via the frame 410. Furthermore, the width of the frame 410 is greater than the thickness of the cleaning brush 500. During actual use, the cleaning brush 500 can push and sweep the straw residue to the opposite side of the frame 410, thereby ensuring that the screen 400 can function normally. Furthermore, the cleaning brush 500 can be placed on the edge of the frame 410 when not in use to avoid interfering with the filtration of the slurry by the screen 400.
[0033] In some embodiments, the brush handle 510 includes a fixed portion 800 and a movable portion 700. Figure 3As shown, the fixed portion 800 is threadedly connected to the screw 600, and the top surface of the movable portion 700 is connected to the bottom surface of the fixed portion 800 via a coil spring 710. In actual use, the bristles 520 are in contact with the upper surface of the screen 400 via the coil spring 710. The bristles 520 can always maintain contact with the screen 400 under the action of the elastic force, thereby improving the cleaning effect of the bristles 520.
[0034] Preferably, a fastening bolt 900 is threadedly connected to the bottom surface of the fixing portion 800, and the nut head of the fastening bolt 900 contacts the coil spring 710. By rotating the fastening bolt 900 to change the length of its extension relative to the fixing portion 800, the coil spring 710 can be adjusted. In this way, the contact force between the bristles 520 and the screen 400 can be varied according to actual needs, thereby achieving different cleaning purposes and cleaning effects.
[0035] In some embodiments, the crushing shaft assembly includes two crushing shafts 200 with different diameters. This design enables the crushing shaft assembly to adapt to a variety of materials and process different projects, thereby improving its flexibility and practicality.
