Description
Technical field
The utility model relates to the coal mining technical field, is specifically related to a kind of coal-winning machine protector.
Background technology
At present, when in mine, carrying out coal mining, coal cinder can drop from the middle and anterior rib of hydraulic support and disorderly fly during the coal-winning machine feed, the front portion of existing coal-winning machine does not have any protector, therefore sometimes in recovery process coal cinder can pound on coal-winning machine, even can fall on the body of pounding the coal-winning machine staff, cause the staff injured, reduce safety, and influenced operating efficiency.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, and can avoid injuring the staff, safe and reliable, the coal-winning machine protector that barrier propterty is good.
In order to reach above purpose, the technical scheme that the utility model adopts is: the coal-winning machine protector, comprise the ear seat of fixedlying connected with the coal-winning machine top cover, described ear seat is provided with turning set, be provided with the angular adjustment bar in the described turning set, described angular adjustment bar is provided with the protection backstop, and the two ends of described angular adjustment bar are provided with the handle for adjusting angle, is respectively equipped with support bar between two side roof parts of described protection backstop and the described angular adjustment bar.
The utility model is also implemented by following measure: the top of described protection backstop is rotated and is provided with the top protection cover.
Described support bar is telescopic support bar.
The beneficial effects of the utility model are: simple in structure, reasonable in design, can avoid injuring the staff, and safe and reliable, barrier propterty is good.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, ear seat; 2, turning set; 3, angular adjustment bar; 4, protection backstop; 5, handle; 6, support bar; 7, top protection cover.
The specific embodiment
As shown in Figure 1, the coal-winning machine protector, comprise the ear seat 1 of fixedlying connected with the coal-winning machine top cover, described ear seat 1 is provided with turning set 2, be provided with angular adjustment bar 3 in the described turning set 2, described angular adjustment bar 3 is provided with protection backstop 4, and the two ends of described angular adjustment bar 3 are provided with the handle 5 for adjusting angle, are respectively equipped with support bar 6 between two side roof parts of described protection backstop 4 and the described angular adjustment bar 3.
The top of described protection backstop 4 is rotated and is provided with top protection cover 7.Can hide the top of coal-winning machine by top protection cover 7, prevent that coal cinder from dropping from the top and injure the staff, further ensured staff's safety when collision.
Described support bar 6 is telescopic support bar.Can regulate the height of support bar 6 so as required, and the angle of rotational angle adjusting rod 3 adjusting protection backstops 4, easy to use.
When the staff starts coal-winning machine and mines; can pass through the angle of handle 5 rotational angle adjusting rods 3 as required; and by the fastener on the turning set 2 it is fixed; thereby make protection backstop 4 be in suitable position; to adapt to the needs of exploiting the space; can effectively stop the coal cinder that disorderly flies because of exploitation by protection backstop 4 like this, protect staff's safety.Can carry out effective support to protection backstop 4 by support bar 6, prevent from use being subjected to the collision of coal cinder and damage or tilt, can strengthen protective effect, improve safety.
The utility model is simple in structure, and is reasonable in design, can avoid injuring the staff, safe and reliable, and barrier propterty is good.
