[0006] A head tail switching device for scraper machine, the scraper conveyor and the switching device, the scraper conveyor includes a distribution groove, a scraper chain assembly installed in the distribution groove, a support shaft supporting the scraper chain assembly to rotate in the distribution groove, the switching device is installed at the rear side of the end discharge port of the scraper conveyor, the switching device includes a track, a counterweight box, a back plate, a guide plate and a closing plate, two tracks are installed in parallel along the movement direction of the scraper conveyor outside the end discharge port of the scraper conveyor, the counterweight box is installed with walking wheels matched with the tracks on both sides and a driving mechanism driving the walking wheels to travel on the tracks, the back plate is installed on the side wall close to the scraper conveyor of the counterweight box, the closing plate is connected to the bottom of the back plate close to the scraper conveyor on one side, and the closing plate is matched with the end batching port, the back plate above the closing plate is installed with a guide plate matched with the scraper chain assembly, the guide plate is arc-shaped, and a supporting plate matched with the scraper chain assembly is installed in the distribution groove between the two support shafts.

[0007] The drive mechanism is selected from either a drive motor or a hydraulic rod.

[0008] The beneficial effects of the head and tail switching device for scraper conveyors provided by this utility model are: by setting the switching device, the material can circulate in the scraper conveyor, effectively avoiding the problem of material accumulating at the end of the feeding port and affecting the normal production of other production systems. Attached Figure Description

[0009] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0012] like Figure 1 As shown in this embodiment, a head-to-tail switching device for a scraper conveyor and a switching device are provided. The scraper conveyor includes a distribution trough 1, a scraper chain assembly 2 installed in the distribution trough 1, and a support shaft 3 supporting the scraper chain assembly 2 to rotate within the distribution trough 1. The switching device is installed on the rear side of the end discharge port of the scraper conveyor. The switching device is only connected to the scraper conveyor when the production system connected to the end discharge port malfunctions. The switching device includes rails 5, a counterweight box 6, a back plate 7, a guide plate 8, and a sealing plate 9. Two rails 5 are installed parallel to each other along the movement direction of the scraper conveyor on the outer side of the end discharge port of the scraper conveyor. The counterweight box 6 is equipped with rails on both sides. The 5-coordinated traveling wheels 10 and the drive mechanism 11 that drives the traveling wheels 10 to move on the track 5. The drive mechanism 11 selects a drive motor or a hydraulic rod according to the space margin at the end of the scraper conveyor. If the margin is large, a drive motor is selected; if the margin is small, a hydraulic rod is selected. The back plate 7 is installed on the side wall of the counterweight box 6 near the scraper conveyor. The sealing plate 9 is connected to the bottom of the back plate 7 near the scraper conveyor, and the sealing plate 9 is adapted to the contour of the end feeding port. A guide plate 8 adapted to the scraper chain assembly 2 is installed on the back plate 7 above the sealing plate 9. The guide plate 8 is arc-shaped. A support plate 4 that fits the contour of the scraper chain assembly is installed in the distribution groove 1 between the two support shafts 3.

[0013] The method of using this utility model is as follows:

[0014] When the production system connected with the end of the scraper conveyor is out of order, the baffle at the end of the scraper conveyor is opened, then the weight box 6 is controlled to move towards the scraper conveyor by the driving mechanism 11, after the movement, the profile of the closing plate 9 just clamps the feeding port of the scraper conveyor, at the same time, the deflector 8 is matched with the running profile of the scraper chain assembly 2, so that the materials gathered at the end of the scraper conveyor are guided by the deflector 8 to fall on the supporting plate 4 and are scraped again along the supporting plate to the direction of the feeding port of the scraper conveyor, so that the materials can flow in a cycle, and when the production system is out of order, the normal operation of other production systems can still be ensured, and the production efficiency is greatly improved.

[0015] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, any modification and replacement based on the technical solutions and inventive concepts provided by the present application should be covered within the protection scope of the present application.
