[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] The detachable middle trough of the present invention is composed of a plurality of middle trough components detachably connected to each other, each of which is a bottom-opening structure, so that the middle trough as a whole is also a bottom-opening structure. The detachable middle trough composed of a plurality of middle trough components is installed on a transfer conveyor, one end of which is connected to the transmission part on the head of the transfer conveyor through the connecting trough section of the transfer conveyor, and the other end is connected to the tail of the transfer conveyor through the telescopic trough section and the unloading section of the transfer conveyor.

[0026] like Figure 1A , Figure 1B , Figure 2A , Figure 2B , Figure 2C , Figure 3A , Figure 3B , Figure 4 and Figure 5 As shown, the middle trough assembly constituting the detachable middle trough of the present invention mainly includes a middle trough body 10, a baffle member 50 and a movable lower wing member 60. The middle trough body 10 is composed of two oppositely arranged trough sides 101 and a middle plate 102 fixed between the two trough sides 101, for example by welding. The baffle member 50 is fixedly installed on the top surface of each trough side 101, and the movable lower wing member 60 is connected to the bottom surface of each trough side 101.

[0027] The ends of each groove side 101 of the middle groove body 10 are respectively provided with end caps 103 on the outside, a connection socket 103a is provided in the end cap 103 at one end, and a connection convex pin 103b is provided on the end cap 103 at the other end, so that two connection sockets 103a at one end and two connection convex pins 103b at the other end are provided in the middle groove body 10 of each middle groove assembly. When a plurality of middle groove assemblies are connected to form the detachable middle groove of the present invention, the two connection convex pins 103b on the middle groove body 10 of one middle groove assembly are correspondingly inserted into the two connection sockets 103a on the middle groove body 10 of another middle groove assembly, and then dumbbells are installed at the connection convex pins 103b and the connection sockets 103a of the two mutually matching end caps 103, so as to connect the two middle groove assemblies to each other. In the same way, a plurality of middle groove assemblies can be connected to each other to form a detachable middle groove.

[0028] A vertical plate 104 is connected between the ends 103 on the outside of both ends of each groove side 101 of the middle groove body 10 , and a notch 104 a is provided in the middle of the bottom of the vertical plate 104 .

[0029] A plurality of bolt holes 106 are arranged on the top panel 105 of each trough side 101 of the middle trough body 10, and a plurality of panel slots 107 are welded downward from the top panel 105. The panel slots 107 are welded all around, with an opening at the top of the top panel 105 and an opening at the bottom. The bolt holes 106 and the panel slots 107 are used to fix and install the baffle member 50 on the top surface of the trough side 101.

[0030] An upper wing plate 108 is provided at the top of each trough side 101 of the middle trough body 10. A plurality of chain stopper mounting holes 108a are provided on the upper wing plate 108 for mounting a chain stopper mechanism. When the tail of the transfer conveyor needs to be moved, the chain stopper mechanism can stop the chain and cooperate with the telescopic trough section of the transfer conveyor to drag the tail forward. In addition, the chain stopper mounting hole 108a can also be used as a hoisting hole to hoist the middle trough assembly when disassembling and assembling the middle trough assembly in the detachable middle trough.

[0031] A pair of hinge blocks 109 is disposed at the bottom of each channel side 101 of the middle channel body 10, and the two pairs of hinge blocks 109 on the two channel sides 101 are symmetrical to each other. Each hinge block 109 is provided with a hinge hole 109a.

[0032] A plurality of vertical ribs 501 are provided at the bottom of the baffle member 50. The number of the vertical ribs 501 is equal to the number of the panel slots 107 on the middle tank body 10. The vertical ribs 501 are matched with the panel slots 107. The vertical ribs 501 are inserted into the panel slots 107. Then, the baffle member 50 is fixedly mounted on the top surface of each slot side 101 of the middle tank body 10 through the bolt holes 106 on the middle tank body 10 and the bolts 20 matched with the bolt holes 106. The mutual cooperation between the vertical ribs 501 and the panel slots 107 increases the bending strength of the baffle member 50. In addition, since an opening is left at the bottom of the panel slots 107, it is convenient to leak impurities dropped between the vertical ribs 501 and the panel slots 107 in time, thereby avoiding the problem of reduced assembly efficiency caused by the difficulty of inserting the vertical ribs 501 into the panel slots 107 due to the accumulation of impurities.

[0033] The movable lower wing plate component 60 includes a clamping plate 601, a bottom plate 602, a lower wing plate 603 and a rib plate 604. The clamping plate 601 is vertically arranged in the middle of the bottom plate 602, and a first pin hole 601a is arranged on the clamping plate 601. The lower wing plate 603 is inclined along the height direction of the clamping plate 601, and its inclination matches the inclination of the two wings of the scraper used in conjunction. One end of the lower wing plate 603 is fixed to the bottom plate 602, and the other end of the lower wing plate 603 is supported and fixed by a plurality of rib plates 604. The clamping plate 601 can be inserted into the notch 104a of the vertical plate 104, and is limited by the first pin hole 601a and the first pin shaft 30 matched with the first pin hole 601a, and the end of the first pin shaft 30 is fixed by a cotter pin. Two pairs of second pin shafts 40 are welded on the bottom plate 602 , and the two pairs of second pin shafts 40 are matched with the hinge holes 109 a on the two pairs of hinge blocks 109 on the two groove sides 101 in a one-to-one correspondence.

[0034] The movable lower wing plate member 60 is conveniently connected and assembled with the middle tank body 10 through the notch 104a on the vertical plate 104 of the middle tank body 10, the first pin hole 601a on the clamping plate 601 of the movable lower wing plate member 60, and the matching first pin shaft 30. The end of the first pin shaft 30 is fixed by a split pin, thereby limiting the movable lower wing plate member 60 to prevent the movable lower wing plate member 60 from flipping when the middle tank drives the scraper chain to move without disengaging the scraper chain, ensuring that the scraper chain is directly lifted and moved together by the lower wing plate 603 of the movable lower wing plate member 60; and when dismantling the middle tank assembly, the first pin shaft 30 is removed by removing the split pin to allow the movable lower wing plate member 60 to rotate and thereby realize its disassembly.

[0035] Through the hinge hole 109a on the hinge block 109 of the middle trough body 10 and the second pin shaft 40 on the bottom plate 602 of the movable lower wing plate component 60, the movable lower wing plate component 60 can be hinged to the middle trough body 10, and the flexible rotation of the movable lower wing plate component 60 relative to the middle trough body 10 is ensured.

[0036] When it is necessary to remove part of the middle tank assembly to adapt to the shifting of the working surface, first remove the connecting convex pins 103b and the dumbbells at the connecting sockets 103a installed at both ends of the middle tank assembly to be removed on the tail side of the transfer conveyor; then remove the first pin shaft 30 on the middle tank assembly to be removed by removing the cotter pin. At this time, the second pin shaft 40 can rotate in the hinge hole 109a under the action of the gravity of the movable lower wing plate member 60, so that the movable lower wing plate member 60 can rotate relative to the middle tank body 10 and droop naturally, and the lower The wing plate 603 no longer supports the scraper chain, so that the scraper chain can be separated from the middle trough assembly to be removed; then the telescopic trough section of the transfer conveyor is retracted, and the middle trough and the telescopic trough section are pulled apart by a distance, and the middle trough assembly to be removed is moved laterally toward the telescopic trough section by using a lifting device, so that the connecting protruding pin 103b and the connecting socket 103a between the middle trough assembly to be removed and the middle trough assembly that remains stationary are disengaged from each other, and then the middle trough assembly to be removed is lifted again, thereby completing the removal of part of the middle trough assembly.

[0037] To sum up, the detachable middle trough of the present invention has a compact structure, occupies a small space, is easy to disassemble, and is highly practical. When the working surface needs to be moved, there is no need to move the entire transfer conveyor. It is only necessary to disassemble the middle trough assembly of an appropriate length to shorten the overall length of the transfer conveyor, and then move the telescopic trough section, unloading section and tail of the transfer conveyor to achieve partial movement, thereby improving the moving efficiency of the transfer conveyor, achieving the purpose of maximum mining, and saving resources.
