Description

Technical Field

[0001] The utility model belongs to the technical field of grain conveying machinery, in particular to a double-side discharging ratio-adjustable multi-point discharging plow. Background Art

[0002] Multi-point unloading plow is a common unloading device, mostly used on belt conveyors. Generally speaking, the unloading point position is divided into two sides, right side and left side, to meet different unloading needs. There are many structures for unloading materials at the unloading point. The most common one is to use a triangular arrow-shaped plow. When the material rushes towards the arrow with the conveyor belt, it is divided into the unloading ports on both sides by the arrow. Under this structure, the quantity ratio of unloading on both sides cannot be adjusted, and it cannot meet the needs of different ratios of unloading on both sides. Summary of the invention

[0003] In order to solve the above problems existing in the prior art, the utility model proposes a multi-point unloading plow with flexible adjustable double-side unloading ratio. The unloading plow adjusts the cutting position of the incoming material by adjusting the tip position of the triangular arrow-shaped plowshare, thereby achieving the adjustment ratio.

[0004] The utility model discloses a double-side unloading ratio-adjustable multi-point unloading plow, comprising a plow frame, a plowshare and a conveyor connecting mechanism; the plowshare is rotatably connected to the plow frame, and the rotation axis is parallel to the plane where the conveyor belt of the conveyor is located; the plow frame is connected to the conveyor connecting mechanism for connecting the conveyor; when the plowshare is rotated to the lowest position, the bottom edge of the baffle plate of the plowshare is attached to the plane where the conveyor belt is located.

[0005] The plowshare also includes a dividing rod; the baffle plate is rectangular in shape and made of flexible material; the left and right sides of the baffle plate are respectively connected to the left and right sides of the plowshare, and the total length between the left and right sides of the baffle plate is greater than the distance between the left and right sides of the plowshare; the dividing rod is movably connected to the plowshare; the dividing rod is on the rear side of the baffle plate, and the dividing rod slides along the left and right directions of the baffle plate against the baffle plate; when the plowshare rotates to the lowest position, the baffle plate and the dividing rod are perpendicular to the plane where the conveyor belt is located;

[0006] There are reinforcing steel wires on the rear side of the baffle plate; there are multiple parallel reinforcing steel wires, and their left and right ends are respectively connected to the left and right sides of the plowshare, and the length of the reinforcing steel wires is the same as the total length between the left and right sides of the baffle plate; at least the bottom reinforcing steel wire is connected to the baffle plate; the reinforcing steel wires are between the baffle plate and the dividing rod.

[0007] The working principle of the unloading plow of the utility model is:

[0008] Since the length of the baffle plate is greater than the distance between its two left and right connection points on the plowshare (set as point a and point b), according to the principle that the sum of the lengths of two sides of a triangle is greater than the length of the third side, the total length from the point where the partition rod is attached to the baffle plate (set as point c) to point a and point b is the total length between the left and right sides of the baffle plate, which is greater than the distance between point a and point b. Figure 4 .

[0009] State 1, distance |ac| is equal to |bc|, then the distance from the dividing rod to point a and point b is the same, and the plowshare evenly divides the unloading amount on both sides of a and b.

[0010] State 2, when the distance |ac| is greater than |bc|, the dividing rod is closer to point b (until it reaches the front of point b, points a, b and c form the three vertices of a right triangle, and point b is the corresponding vertex of the right angle), and the plowshare distributes more unloading amount to point a (until it is completely distributed to point a).

[0011] State 3. Correspondingly, if the distance |ac| is less than |bc|, the dividing rod is close to point a, and the plowshare distributes more discharge amount to point b (until it is completely distributed to point b).

[0012] In engineering implementation, from a functional perspective, the baffle plate needs to be flexible so that it can be supported by the partition rod into the desired shape. However, in order to face the impact of the material, the baffle plate needs to have a certain strength. Therefore, multiple reinforcing steel wires are used behind the flexible baffle plate (the material can be PET, etc.) to support it and improve the supporting strength of the flexible baffle plate.

[0013] In specific implementation, the plow frame includes a gate-shaped frame; the plowshare includes a mouth-shaped frame;

[0014] The left and right feet of the gate-shaped frame are provided with bolt holes for connecting the conveyor, forming a conveyor connection mechanism;

[0015] The left and right ends of the rear connecting rod of the square frame are respectively rotatably connected to the two upright posts of the gate-shaped frame; the left and right ends of the front connecting rod of the square frame are respectively connected to the vertical rods for connecting the left and right sides of the baffle plate;

[0016] The crossbeam of the gate-shaped frame is rotatably connected to the cylinder body of the hydraulic cylinder, and the piston rod of the hydraulic cylinder is rotatably connected to the front connecting rod of the mouth-shaped frame. The rotation axis of the cylinder body and the piston rod of the hydraulic cylinder is parallel to the plane where the conveyor belt is located;

[0017] The partition rod is vertically connected to an elastic telescopic rod;

[0018] The rear end of the elastic telescopic rod is slidably connected to the front connecting rod of the square frame, and the sliding direction is along the left and right direction of the front connecting rod; a sliding driving mechanism is also connected between the elastic telescopic rod and the front connecting rod.

[0019] During implementation, the partition rod can also be a rotating structure, the rear end of the elastic telescopic rod can be rotatably connected to the square frame, the rotation axis is perpendicular to the plane where the conveyor belt is located, and the rotation action can be driven by the rotation connection motor between the elastic telescopic rod and the square frame. This structure has a relatively large torque requirement for the motor, and the power and volume of the motor are relatively large, which is more suitable for large unloading plows.

[0020] Since the trajectory of point c is not a perfect circular arc, an elastic telescopic rod is used to adaptively adjust the distance from point c to line ab.

[0021] Furthermore, a plurality of limit grooves are provided on the partition rod, and each reinforcing steel wire corresponds to a limit groove. This structure increases the stability of the partition rod movement and also prevents the steel wire from sliding up and down.

[0022] Furthermore, for multiple reinforcing steel wires (they are parallel), the spacing between adjacent reinforcing steel wires increases from bottom to top. Because the incoming materials are mainly at the bottom of the baffle plate, it is necessary to increase the support at the bottom.

[0023] There are two types of baffle plates:

[0024] One is that the baffle plate is formed by attaching a PET wear-resistant sheet to the front side of the canvas. Under this structure, the structural strength requirements such as tensile strength of the baffle plate are met, and the wear resistance is achieved by the PET wear-resistant sheet.

[0025] The other is that the baffle plate is composed of ceramic pieces fully pasted on the front side of the canvas; a single ceramic piece is square, and multiple ceramic pieces are fully pasted on the front side of the canvas in a mosaic structure, and the front side of the ceramic piece is smooth; the ceramic pieces are in a matrix shape, and the gap between two adjacent rows of ceramic pieces is parallel to the dividing rod. Under this structure, the canvas serves as a support for the wear-resistant ceramic pieces of the baffle plate, and the gap between two adjacent rows of ceramic pieces meets the bending requirements of the baffle plate.

[0026] Furthermore, the partition rod is passed through a plurality of pulleys from bottom to top; this structure prevents the partition rod from directly rubbing against structures such as a material baffle plate.

[0027] The reinforcing steel wire is connected to the canvas, and the connecting structure is that a cloth belt is sewn on the rear side of the canvas, and the reinforcing steel wire is inserted into the channel between the cloth belt and the canvas. The reinforcing steel wire and the baffle plate are an integrated structure, and the two are relatively stable.

[0028] The plowshare baffle plate structure provided by the utility model can flexibly adjust the double-side unloading ratio and is particularly suitable for unloading of small and medium-sized conveyor belts. BRIEF DESCRIPTION OF THE DRAWINGS
