[0028] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] Please see Figures 1 to 2 This utility model provides a technical solution: a washing machine, including a body 1, a feeding hopper 2 integrally formed on the surface of the body 1, two shafts 11 rotatably connected to the surface of the feeding hopper 2, a guide plate 3 inserted into the surface of the shafts 11, a gear 5 fixedly connected to one end of the shafts 11, a connecting plate 10 slidably connected to one end of the feeding hopper 2, racks 6 fixedly connected to both ends of the connecting plate 10, and stops provided on both ends of the racks 6 to prevent the racks 6 from disengaging from the gears 5. The racks 6 and the gears 5 mesh, the two racks 6 are symmetrically distributed, and each rack 6 meshes with one gear 5, causing the two guide plates 3 to rotate relative to each other. A fixing sleeve 14 is screwed to the other end of the shafts 11.

[0031] Through the cooperation of gear 5, rack 6 and manual lead screw 8, the angle of guide plate 3 can be adjusted according to actual production needs, thereby improving the uniformity of feeding, improving the washing effect and pulp washing quality. By setting a fixed sleeve 14 and screwing the shaft 11, the guide plate 3 can be disassembled and installed separately, improving the maintenance efficiency of the guide plate 3.

[0032] Example 2

[0033] Please see Figures 1 to 4, on the basis of Embodiment 1, in order to adjust the angle of the deflector 3, one end surface of the feed hopper 2 is fixedly connected with a fixing plate 4. The fixing plate 4 is in the shape of a "U" - shaped plate structure. Two auxiliary rods 9 are fixedly connected to the surface of the fixing plate 4. The auxiliary rods 9 provide precise guidance for the sliding of the connecting plate 10, ensuring that the connecting plate 10 always moves in a straight line when moving along the direction of the manual screw rod 8, guaranteeing the stability and accuracy of the gear 5 - rack 6 transmission, making the process of adjusting the angle of the deflector 3 smooth and improving the adjustment accuracy;

[0034] One manual screw rod 8 is rotatably connected to the surface of the fixing plate 4. Bearing seats are arranged at both the top and bottom of the fixing plate 4. The manual screw rod 8 is supported at both ends through the bearing seats. One end of the manual screw rod 8 penetrates through the top surface of the fixing plate 4 and is fixedly connected with a handwheel 7. The handwheel 7 is convenient for driving the manual screw rod 8 to rotate. The connecting plate 10 is in the shape of a square plate structure. The length of the connecting plate 10 is greater than the width of the fixing plate 4, so as not to affect the moving path of the rack 6. Two first round holes are opened on the surface of the connecting plate 10. The auxiliary rods 9 penetrate through the first round holes. A threaded hole is opened on the surface of the connecting plate 10, and the threaded hole is connected with the threaded part on the surface of the manual screw rod 8 in a matching manner;

[0035] The deflector 3 is in the shape of a square plate structure. The total width of the two deflectors 3 is slightly less than the width of the feed hopper 2, avoiding interference between the two deflectors 3 and preventing relative rotation between the deflector 3 and the shaft rod 11. A second round hole is opened on the surface of the deflector 3. Two limiting holes 13 are opened on the surface of the second round hole. The limiting holes 13 are in the shape of "D" - shaped holes. A limiting strip 12 is inserted into the surface of the limiting holes 13. The limiting strip 12 is a convex strip with a cross - section in the shape of "D". Through the mutual cooperation of the limiting holes 13 and the limiting strip 12, the shaft rod 11 can rotate synchronously with the deflector 3, ensuring the stability of the deflector 3 during the angle adjustment and working process, and being convenient for disassembly. Just pull out the shaft rod 11.

[0036] Embodiment 3

[0037] Please refer to Figures 1 to 5 , on the basis of Embodiment 2, in order to disassemble the deflector 3, two limiting strips 12 are fixedly connected to both sides of the surface of the shaft rod 11. The length of the limiting strip 12 is less than the length of the shaft rod 11. External threads 17 are arranged on the surface of the end of the shaft rod 11 far from the gear 5. A gasket 15 is sleeved on the surface of the shaft rod 11. Internal threads 16 are arranged on the surface of the fixed sleeve 14. The internal threads 16 and the external threads 17 are connected in a matching manner. The cooperation of the external threads 17 and the internal threads 16 on the fixed sleeve 14 realizes the detachable connection between the shaft rod 11 and the fixed sleeve 14;

[0038] The gasket 15 is clamped between the feed hopper 2 and the fixed sleeve 14. The gasket 15 is provided, and the gasket 15 is a metal gasket, reducing the wear of the connecting part between the feed hopper 2 and the fixed sleeve 14.

[0039] In actual use, when it is necessary to adjust the flow rate of pulp feed, firstly, the operator turns the handwheel 7, which drives the manual screw 8 to rotate on the fixed plate 4. Since the threaded hole on the connecting plate 10 matches the threaded part of the manual screw 8, the connecting plate 10 will slide along the direction of the auxiliary rod 9. The racks 6 at both ends of the connecting plate 10 mesh with the gear 5 at one end of the shaft 11. The movement of the racks 6 drives the gear 5 to rotate, thereby rotating the shaft 11, realizing the adjustment of the angle of the guide plate 3, guiding the pulp to enter the machine body 1 more evenly, and avoiding insufficient washing of pulp due to concentrated feeding.

[0040] When the guide plate 3 needs to be disassembled and maintained, the operator uses a tool to unscrew the fixing sleeve 14. The fixing sleeve 14 is connected to the external thread 17 on the shaft 11 through the internal thread 16. After unscrewing the fixing sleeve 14, the shaft 11 is disengaged from the gasket 15. Since the second round hole and the limiting hole 13 of the guide plate 3 are connected to the shaft 11 and the limiting strip 12 by plugging, the shaft 11 can be pulled out from the guide plate 3 to complete the disassembly of the guide plate 3. After replacing the new guide plate 3 or maintaining the old guide plate 3, the installation is carried out in reverse order. First, insert the shaft 11 into the corresponding hole of the guide plate 3, then put on the gasket 15, and finally tighten the fixing sleeve 14 so that the gasket 15 is clamped between the feed hopper 2 and the fixing sleeve 14, thus fixing the shaft 11 and the guide plate 3.

[0041] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
