Abstract

The utility model discloses a scraper loader loading automatic spray device, belonging to the mining scraper loaders. An automatic spray device is fixed at one side of the joint place between a scraper loader tail discharge chute and a host transition slot, near a motor; the automatic spray device comprises a fixed frame; a high-pressure spray valve is fixed at the external side of the cross beam of the fixed frame; a handle of the high-pressure spray valve is connected with an extended handle; and both sides of the extended handle are respectively connected on the cross beam of the fixed frame through stayed extension springs. When the vehicle enters the scraper loader tail discharge chute, the wagon automatically drives the extended handle to open the high-pressure spray valve for automatic spraying. When the vehicle exits, the extended handle returns to the original location and the spray automatically stops. The scraper loader loading automatic spray device has the advantages of simple structure and good spray effect, which is easy to use and solves the disadvantages of the original device which sprays water under the conditions of loading and non-loading, so as to save water resources.

Description

Raking loader entrucking automatic sprayer

Technical field

The utility model relates to the raking loader that uses on the mine, specifically is a kind of raking loader entrucking automatic sprayer.

Background technology

For ensureing colliery worker's safety and health.Worker to coal mine operation must take special protective measures, reduces dust suction, dust receiving ring border as far as possible." safety regulations in coal mine " regulation: " when using muck (coal) machine, must on spoil or dump, sprinkle water and wash tunnel rock group." previously used raking loader entrucking spraying facility, the dust that an atomizing de-dusting head flies upward entrucking can only be installed carry out atomizing de-dusting; The shortcoming of this kind measure was all sprayed water when being entrucking with not entrucking, because go down the hill to construct easy ponding, tunnel water funkly, and water is many direct increase worker labour hour, and the end is dragged in not draining meeting, draining just to increase worker's labour intensity.And waste water resource.Original in addition spraying is manually opened before going out car by the worker.Open the atomizing de-dusting head if the worker forgets, the staff then works in the dust atmosphere that flies upward.

Summary of the invention

The purpose of this utility model provides a kind of raking loader entrucking automatic sprayer, to solve the above-mentioned defective that prior art exists, overcomes the drawback that entrucking and not entrucking are all sprayed water, and dust-laying effect is good.

The utility model is realized with following technical scheme: a kind of raking loader entrucking automatic sprayer, and it comprises raking loader, it is characterized in that a side of the close motor of tail blowpit and the excessive groove of main frame junction behind raking loader is fixed with an automatic sprayer; Automatic sprayer comprises fixed mount, is fixed with a high-pressure fog valve in the outside of the crossbeam of fixed mount, is connected with one on the handle of high-pressure fog valve and adds long handle, and the both sides of long handle are connected on the crossbeam of fixed mount by the extension spring that tiltedly draws respectively.

Tail blowpit after vehicle enters raking loader, railway carriage promote to add long handle voluntarily and open high-pressure fog valve auto spraying.After treating that vehicle withdraws from, add long handle and keep in the center and put, spraying stops automatically.

Good effect of the present utility model is: simple in structure, easy to use, spray effect is good, has solved the drawback that original entrucking and not entrucking are all sprayed water, and has saved water resource.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model general structure schematic diagram;

Fig. 2 is the automatic sprayer structural representation.

Among the figure: 1, raking loader, 2, automatic sprayer, 2-1, fixed mount, 2-2, fixing hole, 2-3, oblique frame, 2-4, extension spring support, 2-5, extension spring, 2-6, extension spring, add long handle, 2-8, high-pressure fog valve at 2-7.

The specific embodiment

As shown in Figure 1, the side at raking loader 1 back tail blowpit and the close motor in the excessive groove of main frame junction is fixed with an automatic sprayer 2.

As shown in Figure 2, automatic sprayer is made up of with the parts such as high-pressure fog valve 2-8 of device on rack beam right-angled triangle fixed mount 2-1.Right-angled triangle fixed mount 2-1 is a triangle-frame, is welded with 70 * 70 (mm) angle steel.Tiltedly frame 2-3 uses as reinforcing tripod.On the crossbeam of right-angled triangle fixed mount 2-1 the outside fix high-pressure fog valve 2-8. high-pressure fog valve 2-8 on crossbeam both sides each fix the extension spring support that a usefulness 5 * 70 (mm) band steel is made, respectively weld a ring on it and make to add long handle 2-7 in order to fix the long seamless steel pipe of a 400mm on the handle that articulates extension spring 2-5 and extension spring 2-6. high-pressure fog valve 2-8; A ring is respectively welded in the both sides that add long handle 2-7, and extension spring 2-5 and extension spring 2-6 are articulated in respectively on the ring of extension spring support 2-4 and long handle 2-7 both sides.High-pressure fog valve 2-8 can join a plurality of shower nozzles as required.

With fixing hole 2-2 on the screw Tong Guo Vertical beam automatic sprayer is fixed on tail blowpit and the excessive groove of main frame junction (fixing by that side of motor limit) behind the raking loader then, had both formed raking loader entrucking automatic sprayer as shown in Figure 1.

Operating principle is:

Vehicle enters tail blowpit behind the raking loader, and railway carriage promotes 15mm seamless steel pipe 400mm voluntarily and adds long handle, and the high-pressure fog valve had both been opened water spray automatically and nebulized.It is descending that first car has been adorned vehicle, and spraying is closed, treat that vehicle withdraws from after, the spraying close automatically.Work so repeatedly.
