Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-6 The dust collector of a grain suction machine which is easy to clean is shown, comprising a pulse cylinder 1, a flange cover plate 2 is installed at the upper end of the pulse cylinder 1, the pulse cylinder 1 performs a blowing operation through a pulse valve 3 installed at the upper end, the pulse valve 3 cleans the dust in the cloth bag 4 at the internal position of the pulse cylinder 1 after starting the operation, a support frame 10 is welded at the four corners of the lower end of the pulse cylinder 1, a gas inlet port 8 is installed at the lower end of the pulse cylinder 1, a scraper motor 6 is installed at the left end of the gas inlet port 8, a stainless steel protective net 20 for isolating impurities is fixed at the inner side of the gas inlet port 8, a storage box 9 is installed at the lower end of the gas inlet port 8, a maintenance hole 5 is provided at the front end of the pulse cylinder 1 at the lower position, through holes 18 are provided at the left and right ends of the maintenance hole 5, and the inner wall of the through hole 18 is provided at the left and right ends. A fixing block 19 is fixed at the side position, and a locking bolt 11 is inserted and connected at the internal position of the hole 18. The locking bolt 11 is clamped with the fixing block 19 in the sliding groove 15 located at the left and right end positions. A pressing plate 14 is fixed at the lower end position of the locking bolt 11. The locking bolt 11 is installed with the threaded cap 16 through the threaded structure of the outer wall. A plurality of fixing plates 17 are fixed at the outer wall position of the threaded cap 16, and the threaded cap 16 can be controlled to rotate at the outer wall position of the locking bolt 11 through the fixing plate 17. A protective cover 7 is installed at the front end position of the maintenance hole 5. The installation of the protective cover 7 and the maintenance hole 5 allows the rubber plug 12 located at the inner wall position to be inserted into the inner wall of the maintenance hole 5. The rubber plug 12 enters the inner wall position of the maintenance hole 5, so that the U-shaped grooves 13 located at the front and rear ends of the rubber plug 12 are clamped with the locking bolt 11.

[0026] The pulse cylinder 1 removes dust in the air when the grain sucker is working. When too much sucked dust accumulates in the bag 4, the pulse valve 3 receives the signal and releases compressed air pulses. These pulse airflows enter the bag 4, shake off and remove the dust on the surface of the bag 4, and make it fall into the ash hopper at the bottom. The dust in the ash hopper is cleaned through the maintenance hole 5, so that the dust collector can maintain a normal working state.

[0027] like Figure 1 and Figure 6 As shown, the pulse valve 3 can provide compressed air pulses. The activation of the pulse valve 3 can clean the dust in the cloth bag 4. The cloth bag 4 is provided with multiple locations distributed in the internal position of the pulse tube 1. The pulse tube 1 is supported by a support frame 10 fixed at the four corners of the lower end. The activation of the scraper motor 6 enables the gas inlet 8 to suck the dust in the air into the internal position. The gas inlet 8 is isolated from foreign objects by a stainless steel protective net 20 fixed at the inner wall. The foreign objects isolated by the stainless steel protective net 20 fall into the internal position of the storage box 9. The storage box 9 is installed with the gas inlet 8 through the threaded structure of the inner wall.

[0028] A stainless steel protective net 20 is fixed at the internal position of the gas inlet 8. The stainless steel protective net 20 can isolate large impurities, and the isolated large impurities fall into the internal position of the storage box 9. When the dust removal is completed, the storage box 9 can be rotated to be disassembled for cleaning.

[0029] like Figure 2 and Figure 3 As shown, after the protective cover 7 and the maintenance hole 5 are disassembled, the internal parts of the pulse tube 1 can be repaired through the maintenance hole 5. When the protective cover 7 and the maintenance hole 5 are installed, the rubber plug 12 is inserted into the internal position of the maintenance hole 5. When the rubber plug 12 is inserted into the inner wall of the maintenance hole 5, the U-shaped groove 13 wraps the locking bolt 11 at the inner position. The fixing plate 17 can control the threaded nut 16 to rotate so that the locking bolt 11 moves. The movement of the locking bolt 11 makes the pressure plate 14 fit tightly with the rubber plug 12. The rubber plug 12 is squeezed by the pressure plate 14 and fits tightly on the inner wall of the maintenance hole 5.

[0030] Align the slide grooves 15 at the left and right ends of the locking bolt 11 with the fixing blocks 19, and the locking bolt 11 can be inserted into the internal position of the through hole 18. The threaded cap 16 is installed at the outer position through the thread of the outer wall of the locking bolt 11. A rubber plug 12 is provided at the rear end of the protective cover 7. Align the U-shaped grooves 13 at both ends of the rubber plug 12 with the locking bolt 11, press the protective cover 7 so that the rubber plug 12 is inserted into the internal position of the maintenance hole 5, and at the same time, the U-shaped groove 13 wraps the locking bolt 11 at the inner position, and the threaded cap 16 is rotated at the outer wall position of the locking bolt 11 through the fixing plate 17, and at the same time, the locking bolt 11 is moved. The movement of the locking bolt 11 causes the pressing plate 14 to squeeze the rubber plug 12, so that the rubber plug 12 is tightly fitted with the inner wall of the maintenance hole 5, and the installation of the protective cover 7 and the maintenance hole 5 is completed.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
