Description

Technical Field

[0001] The utility model belongs to the technical field of grain conveying machinery, in particular to a flap-type multi-point unloading plowshare, a unloading plow and a unloading system. Background Art

[0002] The unloading plow is a common unloading device, mostly used on belt conveyors. The unloading plow usually consists of a plow frame, a plowshare, and a conveyor connection mechanism. The plow frame is connected to the frame of the belt conveyor through the conveyor connection mechanism. The plowshare is movably connected to the plow frame, and the plowshare can be raised and lowered. When the plowshare is lowered to the lowest position, the bottom edge of the plowshare's baffle plate sticks to the surface of the conveyor belt, and the material on the conveyor belt enters the unloading position under the blocking and diversion effect of the baffle plate. The plowshare is arrow-shaped, which divides the material into two streams, which enter the feed port of the feed pipe from the unloading points on the left and right sides of the conveyor belt respectively. The unloading on both sides is actually two sub-feed ports entering the same feed pipe, and these two sub-feed ports converge at the feed end of the feed pipe.

[0003] Large-scale storage bases contain multiple grain silos. Material distribution to different silos based on storage requirements can be achieved through distribution valves within the feed pipes. The main problem with this approach is that the distribution valves are installed on the feed pipes. To save space, the feed pipes are often located within the narrow space between silos, making maintenance inconvenient. Furthermore, the grain produces a lot of dust, which is high in starch, which can easily cause dust to accumulate within the distribution valves.

[0004] Therefore, if the material can be directly distributed to the corresponding granary through a single pipeline during the unloading stage, the use of pipeline distribution valves can be reduced or even avoided. Summary of the Invention

[0005] To meet these needs, this utility model proposes a multi-point unloading plowshare with a simple structure, easy maintenance, and low cost. By replacing existing unloading plowshares with this plowshare, material on the conveyor belt can be flexibly distributed to the left and / or right unloading points, allowing one plowshare to serve two separate feed lines. Depending on the number and location of on-site granaries, multiple plowshares can be deployed on the same conveyor belt to meet multi-channel unloading requirements.

[0006] In the design process of the unloading plowshare, a movable plowboard is adopted, and the unloading position is adjusted by changing the shape of the plowboard, so that the unloading position can be changed efficiently with a simple structure.

[0007] A flap-type multi-point unloading plowshare comprises a plowshare frame, a retaining plate, and a plowshare frame connecting mechanism. The retaining plate is connected to the plowshare frame, and the plowshare frame connecting mechanism is mounted on the plowshare frame. The retaining plate comprises two mirror-symmetrical left and right retaining plates, namely a left retaining plate and a right retaining plate. The left and right retaining plates are rotatably connected to the plowshare frame, and the rotation axes lie on the mirror planes of the mirror-symmetrical left and right retaining plates.

[0008] When the unloading plowshare is lowered to the lowest position, there are three positions of the left and right baffles:

[0009] State 1: The left and right baffles are both stationary, and the projections of the left and right baffles on the conveyor belt surface are arrow-shaped, with the tip of the arrow pointing forward, i.e., the direction of incoming material;

[0010] State 2: The left baffle plate rotates, and the right baffle plate is stationary. The projections of the left and right baffle plates on the conveyor belt surface are oblique lines, with the projection line segment corresponding to the left baffle plate in front.

[0011] State three: The left baffle plate is stationary, and the right baffle plate is rotating. The projections of the left and right baffle plates on the conveyor belt surface are oblique lines, and the projection line segment corresponding to the left baffle plate is at the back.

[0012] When in use, the shape of the plowshare is changed by rotating the left and right baffle plates, and the incoming materials are divided into two-side unloading, right-side unloading and left-side unloading in three states.

[0013] Specifically, the plowshare frame is a frame structure; in a top view, the beam at the front of the plowshare frame is arrow-shaped, and the tip of the beam is connected to the baffle plate shaft;

[0014] The rear of the left and right baffle plates are respectively connected to a support frame; the adjacent sides of the two support frames are connected to the baffle plate rotating shaft; the remote sides of the two support frames are respectively connected to the plowshare frame through the first cylinder;

[0015] The connection structure between the side away from the support frame and the plowshare frame is as follows: the cylinder body of the first hydraulic cylinder or the cylinder body of the first air cylinder is rotatably connected to the main body of the plowshare frame, and the piston rod of the first hydraulic cylinder or the piston rod of the first cylinder is rotatably connected to the support frame.

[0016] Adding a support frame behind the baffle plate improves structural strength. Because the baffle plate is a rotating component, the plate itself is insufficient. The use of hydraulic and pneumatic cylinders eliminates sparks generated by motors and other electrical equipment, potentially leading to fire hazards such as explosions in high-dust environments like granaries.

[0017] Furthermore, a canvas belt is connected between adjacent sides of the left and right material baffle plates, the material baffle plate rotation axis is behind the canvas belt, and the bottom edge of the canvas belt is not higher than the bottom edges of the left and right material baffle plates.

[0018] Because the retaining plate's rotating shaft requires a certain amount of space, there is a gap between the adjacent sides of the left and right retaining plates, through which material can slip. The left and right sides of the canvas belt are fixed to the left and right retaining plates, respectively, blocking the retaining plate's rotating shaft and blocking the gap to prevent material from slipping. Furthermore, the canvas belt is low-cost, easy to replace, and made of a dark green, environmentally friendly material, making it suitable for this solution.

[0019] A discharge plow comprises a plow frame, a plowshare and a conveyor connecting mechanism; the plow frame is connected to the frame of a belt conveyor through the conveyor connecting mechanism; the plowshare is connected to the plow frame in a liftable manner, and when the plowshare is lowered to the lowest position, the bottom edge of the material baffle of the plowshare is in contact with the surface of the conveyor belt. The plowshare is characterized in that the plowshare is the aforementioned flip-plate multi-point discharge plowshare.

[0020] Specifically, the plow frame is a gate-shaped frame;

[0021] The rear portion of the plowshare frame is rotatably connected to the two upright posts of the gate-shaped frame, with the rotation axis being parallel to the plane of the conveyor belt of the belt conveyor; the crossbeam of the gate-shaped frame and the main body of the plowshare frame are connected via a second hydraulic cylinder or a second pneumatic cylinder; the cylinder body of the second hydraulic cylinder or the cylinder body of the second cylinder is rotatably connected to the crossbeam of the gate-shaped frame; and the piston rod of the second hydraulic cylinder or the piston rod of the second cylinder is rotatably connected to the main body of the plowshare frame;

[0022] The feet of the two upright posts of the gate-shaped frame are provided with bolt holes for connecting the conveyor, forming a conveyor connection mechanism.

[0023] A discharge system comprises a discharge plow and a feeding pipe; the feeding pipes are independent of each other; the feed port of each feeding pipe is connected to a discharge port of the discharge plow, and the discharge port of each feeding pipe is connected to the feed port of a granary.

[0024] There are multiple unloading plows, each arranged along the conveyor belt's feed path. Each plow has two discharge ports, one on each side of the belt conveyor, each connected to a feed port of a feed pipe. The plows can be conventional or the aforementioned plows.

[0025] Compared to existing systems, this new system provides a highly efficient and easy-to-maintain discharge plowshare. This plowshare can be adapted to existing plows, facilitating technical retrofits. Based on this new plowshare, this new system provides a discharge system that avoids the drawbacks of the feed valves found in existing feed systems. BRIEF DESCRIPTION OF THE DRAWINGS
