[0040] Embodiment:

[0041] Combination Figure 1 and Figure 5As shown, the present invention provides a hopper cover pressing structure of a mixer, comprising a mounting sleeve 1 mounted at the output end of a hydraulic device, a connecting plate 2 mounted on the mounting sleeve 1, pressing plates 3 for pressing the hopper cover mounted at both ends of the connecting plate 2, the pressing plate 3 comprising a plate body 32, pressing rods 34 fixedly mounted at both ends of the plate body 32, a pressing block 35 mounted at one end of the pressing rod 34 away from the plate body 32 through an axis, and since the pressing block 35 is mounted on the pressing rod 34 through an axis, when the hopper cover or the device is tilted, the pressing block 35 can rotate to make the pressing block 3 5 is closely fitted with the hopper cover. Since the pressing plate 3 is arranged at both ends of the connecting plate 2, it is equivalent to that there are two plate bodies 32, and the two plate bodies 32 are respectively located on both sides of the connecting plate 2, and both ends of the plate body 32 are provided with a pressing rod 34. Therefore, when the hopper cover is pressed, pressure is applied at four points at the same time to avoid the hopper cover being tilted or stuck due to uneven force during the pressing process. In order to avoid the rigid contact between the pressing block 35 and the hopper cover and cause damage, a buffer pad is provided at one end of the pressing block 35 close to the hopper cover, and the material of the buffer pad is preferably cotton cloth, linen cloth or rubber material.

[0042] Since a large pressure needs to be applied during the compression of the hopper cover, in order to prevent the plate body 32 from being deformed by force, a reinforcing frame 36 is provided on the plate body 32. The reinforcing frame 36 adopts a triangular structure, and a protrusion is provided at the triangular force point to relieve excessive stress concentration and disperse the stress.

[0043] Combination Figure 2 and Figure 3 As shown, the mounting sleeve 1 includes a sleeve body 11, and the sleeve body 11 is mounted on the output end of the hydraulic device. A plurality of threaded holes for installing bolts 13 are evenly distributed along the circumferential wall of the sleeve body 11. By rotating the bolts 13, the bolts 13 are tightened against the output end of the hydraulic device, thereby achieving the fixation of the sleeve body. A shaft 14 is installed at one end of the sleeve body 11 away from the hydraulic device, and a connecting plate 2 is installed on the sleeve body 11 through the shaft 14. The connecting plate 2 can rotate a small distance around the shaft 14 as the center by connecting with the shaft 14. By rotating the connecting plate 2, when the hopper cover is tilted, after the pressing block 35 contacts the hopper cover, the connecting plate 2 can be tilted accordingly to ensure that the four pressing blocks 35 are in contact with the hopper cover.

[0044] Combination Figure 4As shown, the connecting plate 2 includes a circular sleeve 21 installed on the shaft 14 and a center plate 22 for installing the plate body 32. The circular sleeve 21 is arranged in the middle of the center plate 22. The circular sleeve 21 can ensure that the center plate 22 rotates on the shaft 14. Both ends of the center plate 22 are provided with extension shafts 23 for installing the plate body 32. The plate body 32 is installed on the extension shaft 23 through the installation sleeve 31. The installation sleeve 31 can rotate freely on the extension shaft 23. The rotation of the installation sleeve 31 can change the inclination angle of the plate body 32. , making the device more flexible, a limit block 24 for preventing the pressing plate 3 from falling off is arranged at one end of the extension shaft 23 away from the center plate 22, and the length of the center plate 22 can make the installation position of the pressing plate 3 away from the center position of the hopper cover, so that the force position of the pressing plate 3 on the hopper cover is located at the edge of the hopper cover. In order to prevent the center plate 22 from being deformed by force, a reinforcing rib 25 is arranged on the center plate 22. The reinforcing rib 25 adopts a triangular structure, and a protrusion is arranged at the triangular force point to relieve excessive concentration of stress and disperse the stress.

[0045] Combination Figure 1-Figure 3 As shown, the sleeve body 11 is provided with a flange 12 , the edge of which is rounded, and the sleeve body 11 is provided with a compacting structure 4 for compacting the hopper cover through the flange, and the compacting structure 4 can rotate freely on the flange 12 .

[0046] Combination Figure 6 As shown, the compacting structure 4 includes a center sleeve 41 installed on the flange 12, and the inner wall of the center sleeve 41 is provided with an annular groove 42 of the same shape and size as the flange 12, and the center sleeve 41 is sleeved on the flange 12 through the annular groove 42, and the annular groove 42 can prevent the center sleeve 41 from falling off the flange, and the center sleeve 41 is provided with an extension rod 43, and the extension rod 43 is provided with no less than two, and the extension rods 43 are evenly distributed on the circumferential wall of the center sleeve 41, and a push rod 44 is installed at one end of the extension rod 43 away from the center sleeve 41, and the length of the push rod 44 is the same as the distance from the extension rod 43 when the hopper cover is pressed. During the rotation of the center sleeve 41, the push rod 44 contacts the plate body 32. If the hopper cover is not pressed at a certain position, the hopper cover will tilt upward, so the plate body 32 at this position will bulge upward, and when the push rod 44 rotates to this position, it will squeeze the plate body 32 downward, thereby realizing the compaction function of the hopper cover.

[0047] A gear 45 is coaxially mounted on the center sleeve 41, and the gear 45 is fixedly mounted on the center sleeve 41. A motor 47 is mounted on the sleeve body 11 through a base, and a driving gear 46 is mounted on the output end of the motor 47. The driving gear 46 is meshed with the gear 45 through teeth. When the motor 47 rotates, the meshing of the driving gear 46 and the gear 45 can drive the center sleeve 41 to rotate, thereby realizing the driving of the push rod 44, which plays a role in providing power for the movement of the push rod 44.

[0048] The end of the push rod 44 away from the extension rod 43 is provided with a head protruding from the push rod 44, and the end of the head is provided with a spherical roller, which can rotate freely on the head, and the end of the head on which the spherical roller is installed is provided with a chamfer, and the end of the plate body 32 facing the push rod 44 is provided with an arc groove 33, and the arc groove 33 is provided with a chamfer. The extension line of the arc groove 33 can enclose a circle with the arc groove 33, and the radius of the circle is the same as the axial distance from the head to the center sleeve 41. Therefore, when the push rod 44 rotates through the plate body 32, the head can be located in the arc groove 33, and the length of the head is the same as the depth of the arc groove 33. Since the head and the arc groove 33 are both provided with chamfers, when the plate body 32 is raised, the chamfer can be used to ensure the movement of the head, and the movement of the head can also play a function of compacting the hopper cover.
