Specific implementation

[0025] The utility model will be further explained in detail in combination with the drawings and embodiments.

[0026] Referring to Figure 1 , the embodiment includes material distribution section 1, upper turning section 2 and lower turning section 3, material distribution section 1, the upper turning section 2, the lower turning section 3 are connected in turn from top to bottom, and the chute of material distribution section 1 is connected with the upper belt conveyor head funnel through rectangular end flange, and the bottom outlet of the chute of the lower turning section 3 is in the lower belt conveyor receiving groove.

[0027] Referring to Figure 1 and Figure 2In another embodiment, the material distribution flap can be driven by a manual or pneumatic actuator, and the position of the material distribution flap is usually fixed, and only when the proportion of the material distribution is adjusted, the material distribution flap will be operated. The material distribution flap divides the chute into a material distribution left chute and a material distribution right chute, and the material on the belt conveyor is divided by the material distribution flap into upper layer material and lower layer material, which enters the material distribution left chute and the material distribution right chute respectively.

[0028] The upper turning section 2 is formed by six upper chute outer plates 21 and a transverse partition plate 22, and the upper chute outer plates 21 and the transverse partition plate 22 are all trapezoidal. Three of the upper chute outer plates 21 and the transverse partition plate 22 enclose an upper left chute, and the other three of the upper chute outer plates 21 and the transverse partition plate 22 enclose an upper right chute, that is, the transverse partition plate 22 divides the upper turning section 2 into two parts. Each of the upper left chute and the upper right chute forms a channel separately. The entrances of the upper left chute and the upper right chute are aligned, the channel bodies are gradually staggered, and the exits are completely staggered. Specifically, two of the three upper chute outer plates 21 on one side are offset to the left relative to the vertical line of the ground, and correspondingly, two of the three upper chute outer plates 21 on the other side are offset to the right relative to the vertical line of the ground. The left and right directions of the offset are the left and right directions that can extend to both sides at the entrance, rather than the left and right directions that can only widen at the entrance, so that the channel body is gradually staggered to both sides based on the aligned entrance. The material passes through the upper turning section 2 from top to bottom, and the channels are staggered front and back and misaligned left and right in space under the guidance of the upper chute outer plates 21.

[0029] The lower turning section 3 is formed by six lower chute outer plates 31 and a longitudinal partition plate 32, and the lower chute outer plates 31 and the longitudinal partition plate 32 are also trapezoidal. Three of the lower chute outer plates 31 and the longitudinal partition plate 32 enclose a lower left chute, and the other three of the lower chute outer plates 31 and the longitudinal partition plate 32 enclose a lower right chute, that is, the longitudinal partition plate 32 divides the lower turning section 3 into two parts. Each of the lower left chute and the lower right chute forms a channel separately. The entrances of the lower left chute and the lower right chute are staggered, the channel bodies are gradually aligned, and the exits are completely aligned. Specifically, two of the three lower chute outer plates 31 on one side are offset forward relative to the vertical line of the ground, and correspondingly, two of the three lower chute outer plates 31 on the other side are offset backward relative to the vertical line of the ground. The front and back directions of the offset are the front and back directions of the transverse partition plate 22, so that the channel body is gradually aligned to the middle based on the staggered entrance. The material passes through the upper turning section 2 from top to bottom, and the channels are aligned left and right in space under the guidance of the lower chute outer plates 31.

[0030] In addition, in the material distributing section 1, the upper turning section 2 and the lower turning section 3, the material distributing left groove, the upper section left groove and the lower section left groove are sequentially connected to form an upper material passage, and the material distributing right groove, the upper section right groove and the lower section right groove are sequentially connected to form a lower material passage.

[0031] The implementation principle of the head material non-powered turning device of the belt conveyor in the embodiment of the utility model is as follows:

[0032] When the material on the feeding belt conveyor enters the head material non-powered turning device of the belt conveyor, the material is first separated into upper material and lower material after passing through the material distributing turning plate of the material distributing section 1, and then the two passages are staggered in space under the guide effect of the outer wall of the chute when passing through the upper turning section 2.

[0033] In the lower turning section 3, the two passages staggered in space are aligned left and right in space under the guide effect of the outer wall of the chute, and finally fall onto the lower material receiving conveyor belt arranged perpendicularly or at a large included angle with the feeding conveyor belt, and the upper material falls upstream of the movement direction of the belt conveyor, and the lower material falls downstream of the movement direction of the belt conveyor, so that the lower material of the belt conveyor is finally turned to the upper layer.

[0034] The above are preferred embodiments of the utility model, and do not limit the protection scope of the utility model. In the embodiments, the same parts are denoted by the same reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a specific part. Therefore, any equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
