[0038] Furthermore, a bottom connecting portion for connecting to the ground is provided at the bottom end of the first supporting leg 1 .

[0039] Preferably, the bottom connecting part includes a first connecting block 7 and a second connecting block 8, the top surface of the first connecting block 7 is connected to the bottom end of the first supporting leg 1, the bottom surface of the first connecting block 7 is connected to the top surface of the second connecting block 8 through a connecting rod 9, and the second connecting block 8 is provided with a plurality of connecting holes 10, which are used to connect fixing bolts.

[0040] It should be noted that there are four first support legs 1 and four second support legs 2, wherein the lower part of the first support leg 1 is detachably connected by four steel pipes to stabilize the lower part of the first support leg 1. The top edge of the feed hopper is wrapped with an aluminum alloy edge to improve the hardness of the top edge of the feed hopper and enhance the stability of the feed hopper. The moving rod 6 is a threaded rod that can move horizontally back and forth in the horizontal plate 27.

[0041] Specifically, after the first support leg 1 is transported to the predetermined position, the second connecting block 8 is connected to the connecting rod 9, and then the top of the connecting rod 9 is connected to the bottom surface of the first connecting block 7. The upper and lower ends of the connecting rod 9 are threaded heads, and the bottom surface of the first connecting block 7 and the top surface of the second connecting block 8 are provided with fixing grooves adapted to the threads of the connecting rod 9. The threaded connection between the three is conducive to improving stability. After the second connecting block 8 is fixed, the second connecting block 8 is fixed to the ground by passing the fixing bolt through the connecting hole 10, so that the first support leg 1 can be stably set at the predetermined position. When the lifting mechanism is started, the second support leg 2 can move up and down in the first support leg 1, and the second support leg 2 is raised or lowered by the lifting mechanism to meet the height requirements of actual work.

[0042] In addition, the support assembly is used to bear the lateral pressure of the feed hopper surface, wherein the support assembly is connected to the hopper surface through a conventional threaded rod to maintain stability when the feed hopper is working. At the same time, the support assembly and the feed hopper surface can be disassembled. If a large-diameter feed hopper needs to be replaced, the threaded rod is removed, and the bottom end of the support assembly is hinged and rotated on the first support block 3, and the moving rod 6 is used to move outward to expand the distance, so as to facilitate the installation of a large-diameter feed hopper. The top surface of the first support block 3 is provided with a placement groove 4 for installing the bottom edge of the feed hopper. The placement groove 4 is H-shaped, and the width of the H-shaped placement groove 4 is adapted to the bottom edges of different feed hoppers. The first support block 3 is set with two corresponding to the installation method of the bottom edge of the feed hopper. At the same time, two steel pipes are set on the other two sides of the second support leg 2 to complete the four-side connection, thereby improving the stability of the second support leg 2.

[0043] A steel plate is arranged on the side of the second supporting block 26 to connect to the upper part of the second supporting leg 2 , which is beneficial to the stable operation of the second supporting leg 2 .

[0044] In this embodiment, the lifting mechanism includes a square groove on the upper part of each first supporting leg 1, and at least 5 lifting holes 11 are arranged in sequence from top to bottom on the side of the square groove. A plurality of fixing grooves are correspondingly provided on the lower part of the second supporting leg 2. After the bottom end of the second supporting leg 2 extends into the square groove and slides up and down in the square groove to be stable, the fixing groove and the lifting hole 11 are connected and fixed by an insert rod 12.

[0045] Specifically, when the second supporting leg 2 needs to be raised, the second supporting leg 2 is raised in the square groove. When the fixing groove is aligned with the lifting hole 11, the insertion rod 12 is inserted into the lifting hole 11 and the fixing groove. The fixing groove and the lifting hole 11 are fixed on the same horizontal line, and the insertion rod 12 maintains a stable connection between the lifting hole 11 and the fixing groove. Similarly, when the second supporting leg 2 needs to be lowered, the lifting hole 11 and the fixing groove are connected and fixed by the insertion rod 12. The insertion rod 12 can be provided with a threaded head, and the side wall of the fixing groove can be provided with a thread connected to the threaded head, so that the connection of the insertion rod 12 is more stable.

[0046] In this embodiment, the supporting assembly includes a round rod 22 and a first connecting element 24, one end of the round rod 22 is movably connected to the fixing hole 5, and the other end is rotatably connected to the first connecting element 24; one side of the first connecting element 24 is connected to the top side of the feed hopper, and the other side is plugged into one end of the moving rod 6.

[0047] It should be noted that the first connecting element 24 is an elliptical block, wherein the vertical surface is a plane. One side of the first connecting element 24 is connected to the feed hopper surface, and the rest of the circumference is provided with a plurality of plug holes, so that when the angle of the feed hopper surface is adjusted, the movable rod 6 is plugged into different holes to meet the plug-in fixing function of the feed hopper angle adjustment height change.

[0052] Furthermore, the driving part is a rotating rod 21, which extends laterally out of any first supporting leg 1 and is connected to a driving end.

[0053] Preferably, the driving end is a manual lever or a motor drive.

[0054] It should be noted that the first threaded cone 16 near the driving end has a larger tooth size to facilitate the synchronous rotation of other rods and achieve the synchronous lifting of the second support leg 2. The block 18 is a fixed plate set above the cavity 17, which is used to fix and rotate the threaded rod 19. The manual rod can be connected to the rotating rod 21 with a right-angle rod to complete the drive, and the motor can be a conventional model motor.

[0055] In one example, the driving end is mounted on the outer side of the first support leg 1 connected to the first driving rod 13, and the driving end is started. The rotating rod 21 drives the first threaded cone 16 provided on the first driving rod 13 to rotate, and the rotation of the first threaded cone 16 simultaneously drives the second threaded cone 20 to rotate and the first threaded cone 16 provided on one end of the second driving rod 14 to rotate. Then, the first threaded cone 16 provided on the other end of the first driving rod 13 drives the corresponding second threaded cone 20 to rotate. In addition, the first threaded cone 16 provided on one end of the second driving rod 14 can respectively drive the corresponding second threaded cone 20 to rotate and the first threaded cone 16 on one end of the third driving rod 15 to rotate, and the other end of the third driving rod drives the corresponding second threaded cone 20 to rotate, thus realizing a one-belt multi-link lifting activity, and smoothly driving the second support leg 2 to rise or fall.

[0058] It should be noted that the hydraulic rod 23 has a spherical bottom and a rectangular plate shape at the output end, which is convenient for articulating the moving rod 6. The moving rod 6 is a screw rod. The second connecting element 25 is the same as the first connecting element 24. When the output ends of all hydraulic rods 23 are extended, the hydraulic rod 23 changes the inclination angle with the fixing hole 5 as the base point to adapt to the larger diameter feed connection. At the same time, the angle of the feed hopper surface can also be adjusted.

[0059] Specifically, when the output end of the hydraulic rod 23 on one side is extended and the other end remains unchanged, the angle of the feed hopper surface can be adjusted to adjust the feed hopper opening toward the feeding or discharging direction.
