[0028] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-3 In this embodiment, a screw conveyor with an anti-blocking mechanism includes a conveyor body 1, a mounting platform 2 is fixed on the left side of the conveyor body 1, a conveying motor 3 is fixedly installed on the top surface of the mounting platform 2, a screw shaft 4 is fixed to the output shaft of the conveying motor 3, a feeding chamber 5 is fixed to the left side of the top surface of the conveyor body 1, a fixing box 6 is fixed to the back of the feeding chamber 5, a discharge pipe 8 is fixed to the right side of the bottom surface of the conveyor body 1, vertical plates 10 are fixed on the left and right sides of the bottom surface of the conveyor body 1, an anti-blocking mechanism 7 is provided on the feeding chamber 5, a bottom plate 11 is fixed to the bottom surface of the vertical plate 10, and moving wheels 12 are fixed at the four corners of the bottom surface of the bottom plate 11, a connecting plate 13 is fixed between the front and back sides of the two vertical plates 10, support rods 14 are fixed to the left and right sides of the top surface of the connecting plate 13, and an auxiliary mechanism 9 for improving the stability of the device is provided on the connecting plate 13.

[0030] It should be emphasized that the anti-blocking mechanism 7 is mainly used to prevent blockage during the use of the device, which can effectively improve the efficiency of conveying materials. The auxiliary mechanism 9 mainly increases the friction between the device and the ground, thereby improving the stability of the device when it does not need to be moved.

[0031] See also Figure 4-5In order to prevent blockage during the feeding process, the anti-blocking mechanism 7 includes an anti-blocking motor 701 fixedly installed on the right side of the front inner wall of the fixed box 6, the output shaft of the anti-blocking motor 701 is fixed with a first rotating rod 702, the positive part of the outer surface of the first rotating rod 702 is fixed with a first crushing roller 703, and the back of the outer surface of the first rotating rod 702 is fixed with a driving gear 704. The anti-blocking mechanism 7 also includes a second rotating rod 705 rotatably connected to the left side of the front inner wall of the fixed box 6 through a bearing, the positive part of the outer surface of the second rotating rod 705 is fixed with a second crushing roller 706, and the back of the outer surface of the second rotating rod 705 is fixed with a driven gear 707. The anti-blocking mechanism 7 also includes a driving motor 708 fixedly installed on the right bottom of the feeding chamber 5, and the output shaft of the driving motor 708 is fixed with a stirring part 709.

[0032] Among them, the right end of the screw shaft 4 is rotatably connected to the right side of the inner wall of the conveyor body 1 through a bearing, which can improve the supporting function of the screw shaft 4 without affecting its rotation process. A fixing hole is opened on the left side of the conveyor body 1, and the left side of the screw shaft 4 passes through the fixing hole and extends to the outside of the conveyor body 1, so that the screw shaft 4 can be driven to rotate by the conveying motor 3.

[0033] At the same time, the top ends of the four support rods 14 are respectively fixed to the left and right sides of the front and back of the conveyor body 1, which can improve the supporting effect on the conveyor body 1, and the conveyor body 1 is cylindrical.

[0034] In addition, the front side of the first rotating rod 702 is rotationally connected to the right side of the top of the front side of the inner wall of the feed chamber 5 through a bearing. The first rotating rod 702 can drive the first crushing roller 703 to rotate during the rotation. The front side of the second rotating rod 705 is rotationally connected to the left side of the top of the front side of the inner wall of the feed chamber 5 through a bearing. The second rotating rod 705 can be rotated by the coordinated use of the driving gear 704 and the driven gear 707.

[0035] In addition, the driving gear 704 is meshed with the driven gear 707, so that the first crushing roller 703 and the second crushing roller 706 can rotate in opposite directions. The left end of the stirring part 709 is rotatably connected to the bottom of the left side of the inner wall of the feed chamber 5 through a bearing, thereby improving the support effect on the stirring part 709 and making it more stable during rotation.

[0036] It should be noted that a feed hole matching the feed cavity 5 is opened on the left side of the top surface of the conveyor body 1, so that the material can enter the interior of the conveyor body 1 through the feed hole. A discharge hole matching the discharge pipe 8 is opened on the right side of the bottom surface of the conveyor body 1, so that the material can be discharged from the interior of the conveyor body 1 through the discharge hole.

[0037] See also Figure 6In order to improve the stability of the conveyor body 1 during operation, the auxiliary mechanism 9 includes a movable rod 901 slidably connected to the left and right sides of the top surface of the connecting plate 13, and the bottom movable sleeve of the outer surface of the movable rod 901 is provided with an auxiliary spring 902. The bottom ends of the two movable rods 901 on the same connecting plate 13 are fixed with a fixed plate 903, and the bottom surface of the fixed plate 903 is fixed with an anti-slip pad 904. The top ends of the two movable rods 901 on the same connecting plate 13 are fixed with a top plate 905, and a handle 906 is fixed at the center of the top surface of the top plate 905. Hanging rings 907 are fixed on the left and right sides of the top surface of the top plate 905. The auxiliary mechanism 9 also includes a hook 908 rotatably connected to the left and right sides of the front and back of the conveyor body 1 through a bearing.

[0038] It can be understood that there are clearance holes on both sides of the top surface of the connecting plate 13. The two movable rods 901 on the same connecting plate 13 respectively penetrate the two clearance holes and are slidably connected thereto. The movable rod 901 drives the fixed plate 903 to move in the same direction during the up and down movement.

[0039] It should be noted that the upper and lower ends of the auxiliary spring 902 are respectively abutted between the top surface of the fixed plate 903 and the bottom surface of the connecting plate 13. The elastic potential energy of the auxiliary spring 902 can make the fixed plate 903 move downward automatically. The anti-slip pad 904 is a rubber anti-slip pad. The anti-slip pad 904 fits tightly with the ground, which can increase the friction between the ground and improve the stability of the device.

[0040] Finally, the four hanging rings 907 are respectively located on the same vertical line with the four hooks 908, and the two anti-slip pads 904 are symmetrically distributed front to back, which can improve the aesthetics of the device.

[0041] The working principle of the above embodiment is:

[0042] When the device is in use, the material is put into the feed chamber 5, and then the anti-blocking motor 701 drives the first crushing roller 703 to rotate, and drives the second crushing roller 706 to rotate in the opposite direction under the action of the driving gear 704 and the driven gear 707, so that the material can be crushed by the cooperation of the first crushing roller 703 and the second crushing roller 706, and the crushed material falls downward. At this time, the driving motor 708 drives the stirring part 709 to rotate, and the stirring part 709 stirs the material and makes the material fall into the inside of the conveyor body 1 through the feed hole. This process can prevent the material from being blocked. Then the conveying motor 3 drives the screw shaft 4 to rotate, and the material is conveyed from left to right under the drive of the screw shaft 4, and finally output from the discharge pipe 8 through the discharge hole;

[0043] When it is necessary to carry the device, the top plate 905 can be moved upward by the handle 906, and the fixed plate 903 can be moved upward under the action of the movable rod 901, and finally the hanging ring 907 can be hooked on the hook 908. At this time, the anti-slip pad 904 is separated from the ground. At this time, the moving wheel 12 can be used to improve the convenience of carrying the device. The conveyor body 1 can improve the convenience of moving the device by setting the moving wheel 12. When it moves to the specified position, the auxiliary spring 902 of the fixed plate 903 is squeezed and has elastic potential energy when the fixed plate 903 is moved upward. Therefore, after the hanging ring 907 is removed from the hook 908, the fixed plate 903 moves downward under the action of the auxiliary spring 902, and the anti-slip pad 904 is closely fitted to the ground, thereby improving the stability of the device.
