Description

Technical Field

[0001] The utility model relates to a supporting device for a material return module and belongs to the technical field of sand and gravel aggregate transportation. Background Art

[0002] The main function of the return module on the crushing and screening equipment is to allow the large-size materials after crushing or screening to enter the crusher again for secondary crushing, which can effectively improve the production efficiency of the required materials and improve the utilization rate of raw materials. It is widely used in transportation operations in mining, coal mining, metallurgy, transportation and food industries.

[0003] Current status of the return module support device in the crushing and screening field:

[0004] In crushing and screening equipment, the transfer and transportation of incompletely crushed sand and gravel aggregates are mostly achieved by using a return module. There are two ways to fix the return module in the whole machine. One fixing form is that the tail of the return module is supported by a cylinder and the overall angle is adjusted, and the head is pulled by a wire rope. This fixing form has a relatively complex structure and high cost. At the same time, the pulling of the wire rope can easily lead to instability of the head, resulting in uncertainty in the position of the drop point. Therefore, it is particularly important to seek a return support device with a simple structure, low cost and the ability to accurately locate the drop point. Another support form for the return module is to use a bracket to lift the return module for support. This fixing form has a relatively simple structure and low cost, but it needs to be disassembled and transported during transportation, which is troublesome, and the support position is relatively fixed and it is not convenient to adjust the position of the head drop point. Therefore, it is very necessary to find a return support device that is easy to transport and easy to adjust the head drop point. Summary of the invention

[0005] With the development of the fine sand and gravel aggregate industry, the market has higher and higher requirements for the particle size of sand and gravel aggregates. How to improve the production efficiency of the whole machine through the reasonable arrangement of the return module and meet the market requirements for different particle sizes of sand and gravel aggregates is becoming more and more important.

Therefore, they cannot be understood as limitations on the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 As shown, the utility model discloses a support device for a return material module, including an articulated seat 10, a support frame 20, an adjustment plate 40 and a return material support seat 30. The articulated seat 10 mainly serves to connect the entire machine frame and the support frame 20, and the articulated form can satisfy the large-angle rotation and swing of the support frame 02. The main function of the support frame 20 is to support the return material module. The function of the adjustment plate 40 is mainly to realize the vertical adjustment of the return material module. The function of the return material support seat 30 is to realize the articulated connection, lateral rotation and translation adjustment of the return material module. The specific structure of the above-mentioned components is further explained below.

[0037] like Figure 2 , Figure 3As shown, the articulated seat 10 is a welded body, which is composed of a panel 101, a pair of ear plates 102 facing each other and a plurality of rib plates 103, and the whole is a bilaterally symmetrical structure. The articulated seat 10 can be welded as a whole to the side of the whole machine frame, and a hole is also opened on the panel 101 of the articulated seat, and it is installed on the side of the whole machine frame by bolts. The ear plate 102 and the opening on the support frame 20 can be connected by a pin 202, a washer 204 and a cotter pin 203. There is no other component to block between the two ear plates 102, so that the support frame 20 is convenient to be inserted between the two ear plates 102 for connection and left and right swing. Due to the connection with the pin 202, the support frame 20 can swing with the center line of the pin as the axis. When the whole machine is transported, the support frame 20 can be swung to a state parallel to the whole machine to reduce the transportation width of the whole machine. When the whole machine is working, the support frame 20 can be swung to a state perpendicular to the whole machine to facilitate the support of the return module.

[0038] like Figure 1 , Figure 3 , Figure 4 As shown, the bottom side end of the support frame 20 is inserted into the hinge seat 10 for hinge connection, and the top connection part of the support frame 20 is designed as a flange 201. The flange 201 is provided with at least two arc holes with the axis of the flange as the axis. The middle position of the return material support seat 30 is provided with mounting holes corresponding to the arc holes one by one. The return material support seat 30 is connected to the flange 201 at the upper end of the support frame 20 by bolts 307, nuts 309, washers 309, arc holes and mounting holes; when each nut 308 is loosened, the return material support seat 30 can be rotated horizontally with the axis of the flange as the axis to adjust the position of the drop point of the return material module.

[0039] A further solution is that the mounting hole is a long hole 310 . When each nut 309 is loosened, the return material support seat 30 can translate along the length direction of the long hole 310 on the flange 201 at the upper end of the support frame 20 .

[0040] Preferred solution: Four arc holes are evenly spaced on the flange 201, and four outwardly diverging long holes 310 are opened on the bottom plate of the return material support seat 30. Bolts 307, nuts 308, washers 309 cooperate with the arc holes and long holes 310. On the one hand, the return material support seat 30 can be rotated horizontally relative to the support frame 20 to adjust the position of the drop point of the return material module. On the other hand, the return material support seat 30 can be translated in four directions relative to the support frame 2, thereby realizing the movement of the return material module relative to the entire machine.

[0041] like Figure 1 , Figure 3 , Figure 4As shown, one or at least two stacked adjustment plates 40 are installed between the return material support seat 30 and the support frame 20 to adjust the return material module in the vertical direction, thereby adjusting the height of the blanking material. The structural form of the adjustment plate 40 is the same as that of the top flange 201 of the support frame 20. The return material support seat 30 is connected to the flange 201 at the upper end of the support frame 20 and the adjustment plate 40 through bolts 307, nuts 308, and washers 309.

[0042] like Figure 4 As shown, the return material support seat 30 includes a U-shaped base plate 301 and hinged parts fixed on both sides of the base plate 301; the U-shaped base plate 301 is provided with cross-shaped reinforcing ribs 306 to enhance its overall strength; the hinged parts are composed of a pair of ear plates 302 opposite to each other; the support plate in the return material module is clamped between the two ear plates 302, and is hinged with a pin shaft 303 and a spring pin 304, and the return material module can be rotated along the center line of the pin shaft as the axis to adjust the drop height.

[0043] A further solution is that a threaded hole is provided on the axial end face of the pin shaft 303 , and a screw 305 is installed on the threaded hole, and the pin shaft 303 can be pulled out and inserted by pulling the screw 305 .

[0044] In summary, the utility model has the advantages of simple structure, easy installation, easy transportation, and multi-directional adjustment. It can support the return module, adjust the drop position of the return module, and achieve the purpose of rapid switching between transportation and working states.
