Referring to fig. 1 and 2, the present application provides a scraper, which includes a power box 1, a cab 2, a shovel head 3, and a driving assembly 4 for driving the shovel head to operate, wherein the driving assembly may use an existing structure, an energy supply device 5 for supplying energy to the driving assembly is disposed in the power box, in this embodiment, the energy supply device may use a lithium battery or a diesel engine, a first pipeline 6, a second pipeline 7, and a third pipeline 8 are disposed in the power box from top to bottom, and a filter screen 9 is disposed on a side of the power box away from the cab; one end of the first pipeline is close to the filter screen, and is provided with an exhaust fan 10, and the other end of the first pipeline is communicated with the inside of the cab; one end of the second pipeline is communicated with the inside of the cab, the other end of the second pipeline is close to the energy supply device, and an inlet fan 11 is arranged; one end of the third pipeline is communicated with the second pipeline, the other end of the third pipeline is close to the filter screen, a third electromagnetic valve 16 is installed on the third pipeline, a second electromagnetic valve 15 is installed on the second pipeline, and the second electromagnetic valve is arranged close to the air inlet fan relative to the positions of the third pipeline and the second pipeline; the first pipeline is provided with a bypass pipe 12, one end of the bypass pipe, which is not connected with the first pipeline, is provided with a horn mouth 13, the horn mouth is close to the energy supply device, and the bypass pipe is provided with a first electromagnetic valve 14.
The scraper has the following use modes:
use mode 1: closing the second electromagnetic valve, opening the first electromagnetic valve and the third electromagnetic valve, and opening the exhaust fan, wherein at the moment, the third pipeline and the second pipeline are used for providing external gas for the cab, the first pipeline is used as an exhaust pipeline of the cab and the power box, and the heat emitted by the energy supply device is rapidly exhausted through the horn mouth and the first pipeline;
usage pattern 2: closing the first electromagnetic valve and the third electromagnetic valve, opening the second electromagnetic valve, and opening the exhaust fan and the air inlet fan, wherein at the moment, heat emitted by the energy supply device enters the cab along with air flow through the second pipeline to keep the cab warm, and the air flow is discharged through the first pipeline after heat exchange in the cab; when the device is actually used, the inlet fan is not started when the device does not need to be rapidly circulated;
usage pattern 3: closing the third electromagnetic valve, opening the first electromagnetic valve and the second electromagnetic valve, and opening the exhaust fan and the air inlet fan, wherein at the moment, a part of heat emitted by the energy supply device enters the cab along with the air flow through the second pipeline to preserve heat for the cab, the air flow is discharged through the first pipeline after heat exchange in the cab, and the other part of heat emitted by the energy supply device is rapidly discharged through the horn mouth and the first pipeline.
In actual use, when the third pipeline is used as an air inlet pipeline, dust is easy to accumulate at the position of the filter screen corresponding to the air inlet, and the filter screen is easy to be blocked for a long time, therefore, the applicant also designs that the filter screen comprises a vertical part 9-1, a first inclined part 9-2 and a second inclined part 9-3 which are sequentially arranged from top to bottom, and the inclined directions of the first inclined part and the second inclined part are opposite, so that the connecting position of the first inclined part and the second inclined part forms a folding angle with an opening facing the inside of the power box; an elastic sheet 17 is fixed on the inner side surface of the first inclined part, a ball head 18 is arranged at one end of the elastic sheet, which is not connected with the first inclined part, and the diameter of the ball head is slightly larger than the thickness of the elastic sheet during manufacturing, and the ball head is arranged corresponding to one end of the third pipeline, which is close to the filter screen. In actual manufacturing, the elastic sheet and the filter screen can be manufactured by using a spring sheet. When the structure is used, the elastic sheet is enabled to shake when the third pipeline is used for air inflow, so that the first inclined part is driven to shake, the first inclined part drives the second inclined part and the vertical part to shake, and dust is not easy to adhere to the filter screen. The bulb can enlarge the amplitude of elastic piece for first tilting portion vibration amplitude is bigger, and then makes second tilting portion and vertical portion vibration amplitude bigger, more is favorable to the drop of dust, and especially effect is better when mining in the pit.
When actually making, general exhaust fan is close to vertical portion's top sets up, vertical portion with first tilting portion sets up the fillet in order smooth transition, first tilting portion with second tilting portion sets up the fillet in order smooth transition, is favorable to the bounce-back after the first tilting portion warp like this. As an embodiment, the inclination angle of the first inclined part is larger than the inclination angle of the second inclined part based on the vertical surface, so that when the elastic sheet vibrates, the vibration amplitude of the first inclined part is relatively larger, the inclination angle of the first inclined part becomes smaller in the vibration process, the gravity action of dust is larger relative to the friction force of the filter screen, the dust is easier to fall down, the second inclined part is easier to fall down under the action of gravity due to the inclination, and the vibration of the second inclined part accelerates the separation of the dust and the second inclined part; in addition, because the first tilting portion corresponds the third pipeline setting, therefore, first tilting portion department wind-force is general great, here is easy to block up, once first tilting portion blocks up when serious, it is obvious from fig. 3 that vertical portion and second tilting portion department air inlet are the air intake to the third pipeline, and second tilting portion department air inlet direction is less than vertical portion with vertical direction inclination, and the area that contacts the elastic sheet with vertical portion after the air inlet is great, thereby the balancing surface slope when making the elastic sheet vibration upwards, and then make the vibration balancing surface angle of first tilting portion diminish with vertical direction, more be favorable to the coming off of first tilting portion dust, prevent that the filter screen corresponds the position of third wind channel and block up and influence the third wind channel air inlet, generally, first tilting portion can set up about 45 with respect to vertical direction inclination, the second tilting portion can set up about 30 with respect to vertical direction inclination. As shown in fig. 4, the change of the vibration balance surface of the first inclined portion is shown when the first inclined portion is jammed more seriously, wherein the solid line portion of the spring piece is the vibration reference surface before the jam, and the broken line portion of the spring piece is the vibration reference surface before the jam.
