Abstract

The utility model discloses a float coal recycle machine at an exit on a thin seam coal face, which comprises a float coal transportation device, a left tank, a right tank, a coal blocking board and a coal face scraper conveyor. The float coal transportation device consists of a machine head, a machine tail, a middle groove and a scraper chain. The float coal recycle machine is installed on a wind road at the exit of the coal face close to a coal wall, the machine tail of the float coal transportation device is overlapped on the scrapper conveyor of the coal face, and a machine tail of the scrapper conveyor of the coal face is installed on the left tank. When the float coal transportation device is started up, the float coal in a return wind road at the exit on the coal face passes through the machine tail of the float coal transportation device and is sent into the scrapper conveyor of the coal face and transported out of the coal face, thereby solving the problem that the float coal in the wind road at the exit of the coal surface needs to be recycled by labor in the prior art.

Description

A kind of girdle coal-face upper outlet float coal reclaims machine
Technical field
The utility model relates to the coal mine machinery technical field, and particularly a kind of girdle coal-face upper outlet float coal reclaims machine.
Background technology
Domesticly classify according to coal seam thickness, coal seam thickness is divided into high seam, medium-thickness seam, girdle, ultra-thin coal seam, coal seam thickness is high seam more than 2.5M, and coal seam thickness is a medium-thickness seam at 1.3M---2.5M, and coal seam thickness is a girdle at 1.3M---0.8M.At present, development along with coal mining comprehensive mechanization technology, the unit of research and the comprehensive mechanical mining technology of utilization girdle is more and more, but in the girdle coal-face, when adopting the comprehensive mechanical coal mining technology, because balk, stope transporter lane and return airway all need break seat earth driving transporter lane and return airway, because the transporter lane is equipped with fortune coal equipment, the float coal that working surface coal mining machine is mined and produced to the outlet of transporter lane can be transported float coal by the fortune coal equipment in the transporter lane.But owing to do not transport coal equipment in the return airway, in the coal mining process, the float coal that coal-winning machine is mined and formed to upper outlet, can fall into the return airway base plate, can't utilize the scratch board conveyor of coal-face directly float coal to be transported, the base plate that is higher than return airway because of the scratch board conveyor of coal-face, float coal in the return airway, can only transport coal-face by the scratch board conveyor of the coal-face of manually packing into, adopt the artificial mode of coalingging to reclaim float coal in the return airway, increase labor strength, reduced operating efficiency, and influenced the coal mining speed of coal-face, especially in the exploitation of thin coal bed fully-mechanized mining face, because the fltting speed of coal-face is fast, rely on the float coal at manual recovery return airway upper outlet place, even more serious to the fltting speed influence of fully-mechanized mining working.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of girdle coal-face upper outlet float coal to reclaim machine, float coal recovery machine is installed on the base plate of coal-face upper outlet return airway, the float coal that coal-face upper outlet rib side is formed, kept off in the float coal haulage device by spillplate, start the float coal haulage device, float coal is discharged on the coal-face scratch board conveyor from the tail of float coal haulage device, transport coal-face through scratch board conveyor, solved in the prior art deficiency that the float coal in the girdle coal-face upper outlet return airway need manually reclaim.
The purpose of this utility model is to realize like this, a kind of girdle coal-face upper outlet float coal reclaims machine, comprises stiffener at the bottom of float coal haulage device, left box body, right case, the right case case, right case side direction stiffener, spillplate, coal-face scratch board conveyor tail, coal-face scratch board conveyor; Left box body and right case can be processed into two independently casings, use again is fixed together two casings during installation, also two casings can be processed into a whole casing on ground, transporting the infield, down-hole to installs, coal-face scratch board conveyor tail is installed on the left box body, the float coal haulage device is installed in the right case, is connected with spillplate on the right case, and the tail of float coal haulage device is overlapped on the coal-face scratch board conveyor.
The beneficial effects of the utility model are: the float coal that coal-face upper outlet rib side produces in the coal mining process, kept off in the float coal haulage device by spillplate, start the float coal haulage device, float coal is discharged on the coal-face scratch board conveyor from the tail of float coal haulage device, transport coal-face through scratch board conveyor, solved in the prior art deficiency that the float coal in the girdle coal-face upper outlet return airway need manually reclaim.

Fig. 2 is Fig. 1 vertical view
Fig. 3 is Fig. 1 right view
Fig. 4 is the sectional drawing of Fig. 1
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of girdle coal-face upper outlet float coal reclaims machine, comprises stiffener 8 at the bottom of float coal haulage device 13, left box body 6, right case 7, the right case case, right case side direction stiffener 9, spillplate 10, coal-face scratch board conveyor tail 11, coal-face scratch board conveyor 12.
Described float coal haulage device 13 is by head 1, tail 2, intermediate channel 3, scraper chain 4 constitutes, the transmission principle and the structure of head 1 and tail 2 are identical with existing scratch board conveyor, intermediate channel 3 is crooked intermediate channel, the length and the bend radius of crooked intermediate channel 3, the upper end that can be overlapped on coal-face scratch board conveyor tail 11 according to the tail 2 of float coal haulage device 13 is calculated definite, crooked intermediate channel 3 is provided with the straight transitions groove and is connected respectively with tail 2 with head 1, the structure of crooked intermediate channel 3 and straight transitions groove is identical with the structure of existing scratch board conveyor, scraper chain 4 adopts the scraper chain in the existing noria, bearing rib 5 is processed by general steel plate, its effect is the tail 2 that is used to support float coal haulage device 13, increases the stability of the tail 2 of float coal haulage device 13; The bottom of bearing rib 5 is welded on the edge of left box body 6, the right of bearing rib 5 and right case side direction stiffener 9 weld together, right case side direction stiffener 9 is welded on the demarcation strip of left box body 6 and right case 7, the effect one of right case side direction stiffener 9 is the intensity that can increase casing, the 2nd, bearing rib 5 is played enhancing and stabilization; The material of left box body 6, right case 7, spillplate 10, bearing rib 5, right case side direction stiffener 9 is a general steel plate, and thickness is 20MM.The head of head 1, tail 2 and existing scratch board conveyor is identical with the structure and the transmission principle of tail, and the bend radius of intermediate channel 3 is 1100MM.
