Abstract
The utility model provides a loading mechanism of a roadheader. The loading mechanism comprises a main shovel board and left and right auxiliary shovel boards, wherein left and right star wheels are symmetrically arranged on the main shovel board in the horizontal direction, a left motor connected with the left star wheel and a right motor connected with the right star wheel are arranged at positions, corresponding to the left star wheel and the right star wheel, on the back surface of the main shovel board, and an auxiliary driving device matched with the left motor and the right motor is further arranged between the left motor and the right motor; a discharge groove is formed in the rear end of the main shovel board, a scraping plate is arranged in the discharge groove, and the scraping plate is connected with the auxiliary driving device to be driven. The auxiliary driving device driven by the left and right motors drives the scraping plate to crush and push out coal briquettes in the discharge groove, thereby improving the entire performance and the working efficiency of the loading mechanism; meanwhile, the strength of the joint of the main and auxiliary shovel boards is increased, and the maintenance frequency and the use cost are decreased.
Description
Technical field
The utility model relates to a kind of development machine, relates in particular to a kind of loader mechanism of development machine.
Background technology
Tunnelling is the Foundation Design of coal production and construction, mainly to utilize development machine to tunnel, development machine is mainly made up of walking, cutting, loading, conveying mechanism, and wherein loader mechanism is one of groundwork mechanism of development machine, and its performance directly affects the production capacity of complete machine; It is mainly that the material that cutting mechanism is cut down is collected, is loaded on middle scratch board conveyor, is then transported tunnel, unloading through rear portion rehandle facilities.The loader mechanism of development machine mainly comprises shovel board, rake pawl and drive unit etc.At present, the drive unit of loader mechanism is mainly mounted in the junction of main shovel board and secondary shovel board, this just makes drive unit take the connection space of major and minor shovel board, thereby reduce the bonding strength of major and minor shovel board, in the time of part processing, assembling or dismounting, occur that shovel board working strength is low and deviations is installed, forming difficult processing, the technical problems such as difficult are installed.
In addition, in the process of tunneling machine cutting coal, can constantly there is the avalanche of bulk coal, limit because the discharging opening of loader mechanism is subject to physical dimension, easily cause bulk coal cinder to pile up, affect the operation of loader mechanism.
Utility model content
The utility model is exactly in order to overcome the above problems, and a kind of loader mechanism of development machine is provided, thereby adapts to the turning tunneling construction of fully-mechanized digging machine.
In order to achieve the above object, the utility model provides a kind of loader mechanism of development machine, comprise main shovel board and left and right secondary shovel board, in described main shovel board, horizontal direction is arranged with left and right star-wheel, the back side of described main shovel board is provided with the left motor being connected with left star-wheel, the right motor being connected with right star-wheel corresponding to left star-wheel and the position of right star-wheel, in the middle of described left motor, right motor, be also provided with match with them from drive unit; Described main shovel board rear end is provided with blow tank, in described blow tank, is provided with scraper plate, and described scraper plate is connected and drives from drive unit with described.
Further, described main shovel board front end upper surface is installed with wearing plate.
Further, on the base plate of described blow tank, be equipped with wearing layer.
Loader mechanism of the present utility model is all arranged on left the drive unit of left and right star-wheel motor, right motor in main shovel board, thereby the shortcoming of having avoided drive unit to be located at the shovel board body intensity difference that the connection place of major and minor shovel board causes, the connection between major and minor shovel board is also more convenient simultaneously.
In blow tank, be provided with scraper plate, and scraper plate row when from drive unit drives.In the time of left and right motor operations, not only drive left and right star-wheel to be rotated brokenly coal, carry out work with forward (FWD) is moving from drive unit, drive scraper plate to carry out work from drive unit, the gathering coal being deposited in blow tank is carried out to second-time breakage and it is blown in scratch board conveyor and transported in time.Thereby avoid affecting because of the accumulation of coal cinder in blow tank the broken coal efficiency of left and right star-wheel, improved overall performance and the operating efficiency of loader mechanism.
The utility model is provided with wearing plate at the front end of main scraper plate plate face the most easy to wear, has so both saved cost, can well extend the application life of main shovel board again, and reduce frequency of maintenance simultaneously.
On the base plate of blow tank, wearing layer is set, not only can increases the intensity of blow tank, also solved the problem that causes tearing open machine overhaul because of the heavy wear of blow tank base plate simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model rear elevation;
In figure: the main shovel board of 1-, the left secondary shovel board of 2-1,2-2 right secondary shovel boards, 3-1 left star-wheel, 3-2 right star-wheels, 4-wearing plate, 5-scraper plate, 6-blow tank, the left motor of 7-1,7-2 right motors, 8-is from drive unit.
The specific embodiment
As shown in Figure 1, 2, a kind of loader mechanism of development machine, comprise main shovel board 1 and left secondary shovel board 2-1, right secondary shovel board 2-2, in described main shovel board 1, horizontal direction is arranged with left star-wheel 3-1, right star-wheel 3-2, the back side of described main shovel board 1 is provided with the left motor 7-1 being connected with left star-wheel, the right motor 7-2 being connected with right star-wheel corresponding to left star-wheel and the position of right star-wheel, in the middle of described left motor 7-1, right motor 7-2, be also provided with match with them from drive unit 8; When left motor 7-1,7-2 work of right motor, drive and carry out work from drive unit 8, drive unit 8 drives the scraper plate 5 in the blow tank 6 of being located at main shovel board 1 rear end to carry out work, coal cinder in blow tank 6 is carried out to fragmentation and releases, avoided the accumulation of coal and affect the service behaviour of whole loader mechanism.
Further, described main shovel board 1 front end upper surface is installed with wearing plate 4, thereby has protected main shovel board 1 front end face easy to wear, has extended the application life of main shovel board 1.On the base plate of blow tank 6, be equipped with wearing layer, increase the intensity of blow tank, also extended the application life of blow tank simultaneously, reduce maintenance frequency and reduce cost.
Above-described embodiment is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model and all belonging in protection domain of the present utility model of modifying or change.
