Description

[0001] The utility model application is the divisional application of the invention with the application number "202422156622.5", the application date "2024.09.04" and the name "turning plate type multi-point unloading plow head, unloading plow and unloading system". TECHNICAL FIELD

[0002] The utility model belongs to the technical field of grain conveying machinery, and specifically relates to a turning plate type multi-point unloading plow head, unloading plow and unloading system. BACKGROUND

[0003] The unloading plow is a common unloading device and is usually used on a belt conveyor. The unloading plow usually comprises a plow frame, a plow head and a conveyor connecting mechanism. The plow frame is connected to the rack of the belt conveyor through the conveyor connecting mechanism. The plow head is movably connected to the plow frame, and the plow head can be lifted and lowered. When the plow head is lowered to the lowest position, the bottom edge of the baffle plate of the plow head is attached to the surface of the conveying belt, and the material on the conveying belt enters the unloading position under the blocking and flow guiding action of the baffle plate. The plow head is arrow-shaped, which divides the material into two streams and enters the feeding port of the feeding pipe from the left and right unloading points of the conveying belt. The two unloading points actually enter two sub-feeding ports of the same feeding pipe, and the two sub-feeding ports converge at the feeding end of the feeding pipe.

[0004] There are multiple grain stores in a large storage base, and the material distribution allocated to different grain stores according to the storage requirements can be distributed in the feeding pipe through a material distribution valve. The main problem of this mode is that the material distribution valve is installed on the feeding pipe, and in order to save space and other purposes, the feeding pipe is usually in a narrow space between the grain stores, and the maintenance is not very convenient. However, there is a lot of dust and a lot of starch in the dust, which is easy to cause the dust in the material distribution valve to adhere.

[0005] Therefore, if the material can be directly distributed to the corresponding grain store through a single pipe during the unloading stage, the use of the pipe material distribution valve can be reduced or even avoided. SUMMARY

[0006] In order to meet the needs, the utility model provides a multi-point unloading plow head with simple structure, easy maintenance and low cost. After the existing unloading plow is replaced with the unloading plow head, the material on the conveying belt can be flexibly distributed to the left and / or right unloading points, and one unloading plow can correspond to two separate feeding pipes. According to the number and position of the grain stores on site, multiple unloading plows can be arranged on the same conveying belt to meet the multi-path unloading requirement.

[0007] During the design of the unloading plow head, the movable plow plate is adopted, the unloading position is adjusted by changing the shape of the plow plate, and the unloading position is efficiently changed with a simple structure. The utility model is as follows.

[0008] The application discloses a turning plate type multi-point unloading plow head which comprises a plow head frame, a material blocking plate and a plow frame connecting mechanism, wherein the material blocking plate is connected to the plow head frame, and the plow head frame is provided with the plow frame connecting mechanism.

[0009] When the unloading plow head is lowered to the lowest position, the left and right material blocking plates have three positions, respectively as follows.

[0010] State one: the left and right material blocking plates are both static, and the projections of the left and right material blocking plates on the surface of a conveying belt are arrowhead shapes, with the tips of the arrowheads being directed to the front, i.e. the incoming material direction.

[0011] State two: the left material blocking plate is rotated, the right material blocking plate is static, and the projections of the left and right material blocking plates on the surface of the conveying belt are diagonal line shapes, with the projection line segment corresponding to the left material blocking plate being in the front.

[0012] State three: the left material blocking plate is static, the right material blocking plate is rotated, and the projections of the left and right material blocking plates on the surface of the conveying belt are diagonal line shapes, with the projection line segment corresponding to the left material blocking plate being in the rear.

[0013] During use, the shape of the plow head is changed through the rotation of the left and right material blocking plates, and the incoming material is divided into two-side unloading, right-side unloading and left-side unloading in the three states.

[0014] Specifically, the plow head frame is a frame structure; in a top view, the beam at the front of the plow head frame is in an arrowhead shape, and the tip of the beam is connected to a material blocking plate rotating shaft.

[0015] The rear of each of the left and right material blocking plates is connected with a supporting frame; the adjacent sides of the two supporting frames are connected to the material blocking plate rotating shaft; and the sides away from each other of the two supporting frames are connected to the plow head frame through first air cylinders respectively.

[0016] The connection structure between the side away from each other of the supporting frame and the plow head frame is that the cylinder body of the first hydraulic cylinder or the cylinder body of the first air cylinder is rotationally connected to the main body of the plow head frame, and the piston rod of the first hydraulic cylinder or the piston rod of the first air cylinder is rotationally connected to the supporting frame.

[0017] The supporting frame added behind the material blocking plate improves the structural strength; here, since the material blocking plate is a rotating part, only the plate itself cannot meet the structural requirement. The hydraulic cylinder / air cylinder is adopted, so that the electric spark generated in the working process of the motor and other electrical appliances is avoided, and the fire hazard such as explosion in the high-dust environment of the granary is avoided.

[0018] Further, the adjacent sides of the left and right material blocking plates are connected with a canvas belt, the material blocking plate rotating shaft 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 blocking plates.

[0019] Because the structure of the material blocking plate rotating shaft needs to occupy a certain space, there will be some gaps between the adjacent sides of the left and right material blocking plates, and the material will slide away from the gaps. The left and right sides of the canvas belt are fixed on the left and right material blocking plates respectively, and block the material blocking plate rotating shaft, thereby blocking the gaps to prevent the material from sliding away. Meanwhile, the canvas belt is low in cost, convenient to replace, and made of deep green environmentally friendly material, and is suitable for use of the scheme.

[0023] The foot of the two columns of the door-shaped frame is provided with a bolt hole for connecting the conveyor, which constitutes the conveyor connecting mechanism.

Here, the unloading plough can be a traditional unloading plough or the aforementioned unloading plough.

This plough head can be applied to the existing unloading plough, facilitating the technical transformation of the existing unloading plough. Based on the new unloading plough, the present application proposes an unloading system, which can avoid the drawbacks of the existing feeding system. BRIEF DESCRIPTION OF DRAWINGS
