Detailed Description

The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings to facilitate further understanding of the present invention by those skilled in the art, and should not be construed as limiting the scope of the present invention.

Example 1: referring to fig. 1-4, a cross side-discharging headstock of a scraper conveyor comprises a headstock body 1, wherein a scraper conveyor upper chain middle plate 2, a headstock middle plate 3, a headstock partition plate 4 and a headstock bottom plate 5 are fixedly arranged on the headstock body 1 towards the feeding direction of the scraper conveyor; a scraper conveyor chain loading channel is arranged above the scraper conveyor chain loading channel middle plate 2, a reversed loader chain loading channel is arranged between the scraper conveyor chain loading channel middle plate 2 and the headstock middle plate 3, a scraper conveyor chain unloading channel is arranged between the headstock middle plate 3 and the headstock partition plate 4, a reversed loader chain unloading channel is arranged between the headstock partition plate 4 and the headstock bottom plate 5, and the scraper conveyor chain loading channel, the reversed loader chain loading channel, the scraper conveyor chain unloading channel and the reversed loader chain unloading channel are arranged in a crossed manner; a chain channel middle plate 6 on the reversed loader is arranged on the headstock middle plate 3, and a limiting hole 7 is arranged in the middle of the headstock middle plate 3; the transfer machine upper chain middle plate 6 is composed of an upper plate 61 and a lower plate 62 which are fixed by welding, the upper plate 61 of the transfer machine upper chain middle plate 6 is lapped on the headstock middle plate 3, and the lower plate 62 of the transfer machine upper chain middle plate 6 is arranged in the limiting hole 7;

a first elevating conveyor upper chain pressing chain plate 8 and a second elevating conveyor upper chain pressing chain plate 9 are arranged between the scraper conveyor upper chain middle plate 2 and the elevating conveyor upper chain middle plate 6, the first elevating conveyor upper chain pressing chain plate 8 is arranged on one side close to the headstock body 1, and the second elevating conveyor upper chain pressing chain plate 9 is arranged on one side far away from the headstock body 1; the side edge of a chain pressing plate 8 on the first reversed loader is installed on the headstock body 1 through bolts and nuts, the top of a chain pressing plate 9 on the second reversed loader is welded and fixed at the bottom of a middle plate 2 on the scraper conveyor, and the bottoms of the chain pressing plate 8 on the first reversed loader and the chain pressing plate 9 on the second reversed loader are lapped on an upper plate 61 of a middle plate 6 on the reversed loader; two sides of a middle plate 2 of a chain on the scraper conveyor are arranged on the headstock body 1 through bolts and nuts.

The working process of the cross side-discharging headstock of the scraper conveyor is as follows: the upper and lower chain paths of the scraper conveyor and the reversed loader are separated by a chain wheel, the upper chain path is arranged above the chain wheel, and the lower chain path is arranged below the chain wheel. The upper chain channel of the scraper conveyor moves in the upper chain channel of the scraper conveyor, and the lower chain channel of the scraper conveyor moves in the lower chain channel of the scraper conveyor; the upper chain channel of the transfer conveyor moves in the upper chain channel of the transfer conveyor, and the lower chain channel of the transfer conveyor moves in the lower chain channel of the transfer conveyor. Thus, the upper and lower chain paths of the scraper conveyor and the reversed loader cross each other. Coal blocks conveyed by the chain on the scraper conveyor pass through the chain middle plate 2 on the scraper conveyor, fall into the chain middle plate 6 on the transfer conveyor from the opening and are conveyed out by the chain on the transfer conveyor.

Spacing hole 7 carries on spacingly to elevating conveyor upper chain way medium plate 6 in the horizontal direction, and first elevating conveyor upper chain way pressure link joint 8 and second elevating conveyor upper chain way pressure link joint 9 carry on spacingly to elevating conveyor upper chain way medium plate 6 in the vertical direction. When the chain channel middle plate 6 on the transfer conveyor needs to be replaced, the chain channel chain pressing plate 9 on the second transfer conveyor can be taken down only by detaching the bolt and the nut for fixing the chain channel middle plate 2 on the scraper conveyor. Then the bolt and the nut for fixing the chain pressing plate 8 on the first reversed loader are dismounted, and the chain pressing plate 8 on the first reversed loader can be taken down; finally, the lower plate 62 is taken out of the limiting hole 7, and the middle plate 6 of the upper chain of the transfer conveyor can be dismounted.

Example 2: referring to fig. 1 and 4, in the cross side-tipping headstock of the scraper conveyor in embodiment 1, the lower plate 62 is a square plate, and the limiting hole 7 is a square hole.

The square lower plate 62 is matched with the limiting hole 7, so that the middle plate 6 on the transfer conveyor is prevented from swinging in the horizontal direction, and the mounting is more stable.
