Description

Technical Field

[0001] This utility model relates to the technical field of mechanical unloading equipment, specifically to a flip-top type adjustable flexible discharge gate structure. Background Technology

[0002] In mixing, storage, and transportation systems for bulk materials such as powders and granules, the discharge gate at the bottom of the discharge cylinder is a key component for achieving sealed discharge. Traditional discharge gates use a simple fixed design in conjunction with a rotating discharge cylinder for sealing. This cannot be coordinated with an automatic opening and closing mechanism for the discharge gate. When the discharge cylinder rotates, relative displacement easily occurs between the discharge gate and the cylinder body, leading to wear and leakage at the sealing interface. Furthermore, the lack of an effective compensation mechanism during discharge gate installation makes it difficult to ensure a reliable mechanical seal between the discharge gate and the cylinder opening. Utility Model Content

[0016] Furthermore, an inclined block is fixed on the upper surface of the horizontal plate, and inclined surfaces are provided on the lower surface of the horizontal plate and the lower surface of the base. The inclined surfaces have the same slope as the upper surface of the inclined block. The pre-tightening threaded hole is opened through between the upper surface of the inclined block and the inclined surface of the horizontal plate, and the axial direction of the pre-tightening threaded hole is perpendicular to the inclined surface. One end of the compression spring extends into the pre-tightening threaded hole.

[0017] Furthermore, the connecting plate has two square grooves on its surface, and the lower surface of the horizontal plate has two fastening screw holes. The fastening screw holes are threaded with fastening bolts, and the fastening bolts pass through the square grooves and their heads abut against the connecting plate surfaces on both sides of the square grooves.

A compression spring provides an upward-sloping preload, ensuring the discharge gate always presses firmly against the cylinder opening. Positioning bolts engage with the first and second through slots, allowing for slight vertical movement of the base to automatically compensate for cylinder deformation or vibration displacement. Lateral compensation: the inclined compression spring generates a horizontal component force, pushing the discharge gate for slight lateral adjustment, ensuring a tight closure.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See attached document Figure 1-5This utility model proposes a flip-top type adjustable flexible discharge gate 4 structure, including a cylinder 1, a linkage 2, an adjustment component 3, and a discharge gate 4. The cylinder 1 drives the adjustment component 3 through the linkage 2, and the adjustment component 3 drives the discharge gate 4 to open and close. The discharge gate 4 is connected to the lower part of the unloading cylinder. The discharge gate 4 rotates synchronously with the cylinder and can ensure the sealing effect of the discharge gate 4; specifically:

[0031] The linkage 2 includes a rocker arm 21, a rotary shaft 22, and a connecting plate 23; one end of the rocker arm 21 is hinged to the piston rod end of the cylinder 1; both ends of the rotary shaft 22 are rotatably supported by bearing seats, one end of which extends out of the bearing seat and is fixedly connected to the other end of the rocker arm 21; the connecting plate 23 is fixed in the middle of the rotary shaft 22; the adjusting assembly 3 is detachably installed on the connecting plate 23; the adjusting assembly 3 includes at least a base 31 and a bearing sleeve 32 fixed on the base 31; a rotating shaft 46 is fixedly provided at the center of the lower surface of the discharge gate 4; the lower end of the rotating shaft 46 extends into the bearing sleeve 32 and is rotatably connected to the bearing sleeve 32 through a bearing provided between the bearing sleeve 32 and the rotating shaft 46. When the cylinder rotates, the discharge gate 4 drives the rotating shaft 46 to rotate within the bearing sleeve 32. The discharge gate 4 and the cylinder remain relatively stationary, effectively ensuring the sealing effect of the contact interface between the two during rotation. At the same time, the discharge gate 4 is connected to the adjustment component 3, which is connected to the connecting plate 23. When the cylinder 1 extends or retracts, the cylinder 1 drives the rocker arm 21, the rotating shaft 22 and the connecting plate 23 to rotate, thereby driving the discharge gate 4 to open and close through the adjustment component 3.

[0032] In this embodiment, the adjustment assembly 3 further includes a back plate 33, a horizontal plate 34 fixedly connected to the front side of the back plate 33, a pre-tightening bolt 35, and a compression spring 36. The horizontal plate 34 is detachably connected to the connecting plate 23. One end of the horizontal plate 34 extends to the outside of the connecting plate 23, and a pre-tightening threaded hole 341 is formed at this end from bottom to top. The pre-tightening bolt 35 is threaded into the pre-tightening threaded hole 341. The compression spring 36 is pressed between the end face of the pre-tightening bolt 35 and the lower surface of the base 31. The surfaces of the horizontal plate 34 and the connecting plate 23 are respectively provided with a first through groove 342 and a second through groove 231. A positioning bolt 39 is fixed to the lower surface of the base 31. The positioning bolt 39 passes through the base 31 in sequence. The first through groove 342 and the second through groove 231 are connected. The width of the first through groove 342 and the second through groove 231 are basically the same as the outer diameter of the positioning bolt 39 to adapt to the fit. However, the length of the first through groove 342 and the second through groove 231 is greater than the outer diameter of the positioning bolt 39. Therefore, the positioning bolt 39 can move laterally in the first through groove 342 and the second through groove 231. The lower end of the positioning bolt 39 is threaded with a nut, and the nut abuts against the surface of the connecting plate 23 on the outside of the second through groove 231. The compression spring 36 presses upward against the base 31, which in turn causes the discharge gate 4 to press against the lower opening of the discharge cylinder. When the nut is tightened, it limits the maximum upward movement of the base 31 to prevent the discharge gate 4 from loosening. The depth to which the pre-tightening bolt 35 is screwed into the pre-tightening threaded hole 341 controls the clamping force between the compression spring 36 and the base 31. The combination of the compression spring 36 and the positioning bolt 39 controls a small vertical displacement compensation for the discharge gate 4. At the same time, the positioning bolt 39 has a small lateral displacement compensation within the first through groove 342 and the second through groove 231. This allows the discharge gate 4 to automatically compensate for alignment during the closing process, ensuring a tight fit and close at the lower opening of the discharge cylinder.

[0033] Furthermore, a wedge block 37 is fixed to the upper surface of the horizontal plate 34, and inclined surfaces are provided on the lower surfaces of the horizontal plate 34 and the base 31, with the same slope as the upper surface of the wedge block 37. A pre-tightening threaded hole 341 is provided between the upper surface of the wedge block 37 and the inclined surface of the horizontal plate 34, and the axial direction of the pre-tightening threaded hole 341 is perpendicular to the inclined surface. One end of the compression spring 36 extends into the pre-tightening threaded hole 341. By tilting the pre-tightening bolt 35 and the compression spring 36, the base 31 is subjected to tilted pressure. The vertical component of this pressure causes the discharge gate 4 to be pressed upward, and the horizontal component causes the discharge gate 4 to move laterally for automatic adjustment and alignment compensation, ensuring a tight fit between the discharge gate 4 and the mating sealing opening. The pressure direction of the tilted compression spring 36 is perpendicular to the inclined surface of the lower surface of the base 31, ensuring the stability of the compression spring 36 during pressing.

[0034] In this embodiment, the horizontal plate 34 has a certain lateral adjustment space relative to the connecting plate 23 to ensure that the discharge gate 4 can be precisely adjusted laterally before being put into use. Specifically, two square grooves 232 are provided on the surface of the connecting plate 23, and two fastening screw holes 343 are provided on the lower surface of the horizontal plate 34. Fastening bolts 5 are threaded into the fastening screw holes 343. The fastening bolts 5 pass through the square grooves 232 and their heads abut against the surfaces of the connecting plate 23 on both sides of the square grooves 232. The length of the square grooves 232 is greater than the outer diameter of the fastening bolts 5, and the width of the square grooves 232 is basically the same as the outer diameter of the fastening bolts 5 and fits them appropriately. The fastening bolts 5 have a small lateral displacement within the square grooves 232. When the fastening bolts 5 are tightened with nuts, the horizontal plate 34 is fixed above the connecting plate 23. A convex plate 38 is fixedly connected to the lower surface of the horizontal plate 34. A horizontal hole 381 is opened on the surface of the convex plate 38. An adjusting screw hole 233 is opened on the end face of the connecting plate 23 facing the convex plate 38. An adjusting bolt 6 is threadedly connected to the horizontal hole 381, and the end of the adjusting bolt 6 is threadedly connected to the adjusting screw hole 233. Before adjustment, the control cylinder 1 is extended and retracted to move the discharge gate 4 to a position close to the closed position. The nuts that match the fastening bolt 5 and the positioning bolt 39 are loosened. The adjusting bolt 6 is rotated to move the horizontal plate 34 laterally. The discharge gate 4 is pushed to a lateral position that can be aligned with the opening to be closed. Then the nuts that match the positioning bolt 39 and the fastening bolt 5 are tightened.

[0035] In this utility model, the discharge gate 4 includes a top plate 41, a middle plate 42, a positioning ring 43, a sealing ring 44, and a blocking ring 45 stacked sequentially from top to bottom. The top plate 41, middle plate 42, and positioning ring 43 are connected by bolts threaded into pre-set coaxial screw holes on them. The positioning ring 43 and blocking ring 45 are connected by bolts threaded into pre-set coaxial screw holes on them. A base plate coaxial with the middle plate 42 is fixedly connected to the center of its lower surface by bolts, and a rotating shaft 46 is fixedly connected to the center of the bottom surface of the base plate. The edge of the blocking ring 45 is bent downwards to form an annular structure between the blocking ring 45 and the positioning ring 43 to accommodate the embedded sealing ring 44. A beveled cut is provided on the outer side of the upper surface of the sealing ring 44. An inclined chamfer is pre-formed on the inner side of the lower edge of the discharge cylinder to mate with the beveled cut.
