The invention provides a kind of Chaining device and slat conveyer, the defective that slides down in order to solve chain of the prior art can auomatic fixing chain, improves mining efficient and safety.

The invention provides a kind of Chaining device, comprise the upper track piece be used to the chute bottom that is installed in slat conveyer, described upper track piece has at least one supporting oblique surface, and the supporting oblique surface of described upper track piece and the bottom surface of described chute have the angle of 5-15 degree.

Preferably, described upper track piece comprises side plate and swash plate of two rectangular triangles, and the square edge of two described side plates is captiveed joint with the dual-side of the bottom surface of described chute; Described swash plate is captiveed joint with the hypotenuse of two described side plates.

Preferably, described upper track piece comprises side plate and two swash plates of two rectangular triangles, and the square edge of two described side plates is captiveed joint with the dual-side of the bottom surface of described chute; Each described swash plate is captiveed joint with the hypotenuse of a described side plate respectively.

Preferably, the bottom surface of the supporting oblique surface of described upper track piece and described chute has the angle of 8-11 degree.

Preferably, the length of described upper track piece is 300-700mm.

The present invention also provides a kind of slat conveyer, comprises chute and chain, and this slat conveyer is equipped with above-mentioned Chaining device, and described Chaining device is installed in the bottom of described chute.

The invention provides Chaining device and slat conveyer, when slat conveyer generation chain slides down, can chain be introduced in the key way by the supporting oblique surface of upper track piece, realize auomatic fixing chain, cochain is simply easy, can improve production efficiency and the safety of mining.

The specific embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.

With reference to Fig. 2 and Fig. 3, the front view of the Chaining device that Fig. 2 provides for first embodiment of the invention; Fig. 3 is along the cutaway view of A-A line among Fig. 2.

In the first embodiment of the present invention, Chaining device comprises that upper track piece 4 has at least one supporting oblique surface be used to the upper track piece 4 of chute 1 bottom that is installed in slat conveyer, and the bottom surface of the supporting oblique surface of upper track piece 4 and chute 1 has the angle of 5-15 degree.
