The straight chute 7 has the advantages of simple structure, easy manufacturing and low cost. However, when the straight chute is too long or too high, the bagged cement bags will exit the chute at too fast a speed, which will affect the continuous production of bagged cement bags.

[0019] The utility model is further explained below in combination with the drawings and specific embodiments.

[0020] As Figure 1 , Figure 2 The utility model discloses a chute for bagged cement bag conveying, which comprises a material guide structure 1 and an S-shaped groove body 2. The S-shaped groove body 2 comprises an upper arc segment 3, a transition segment 4 and a lower arc segment 5 connected together in sequence from top to bottom. The height of the S-shaped groove body 2 is 1.2-2 m. A conveying through hole 6 is arranged in the middle of the S-shaped groove body 2. The conveying through hole 6 is S-shaped from top to bottom. The material guide structure 1 is connected with the upper end of the S-shaped groove body 2 and is arranged in an inclined manner. The material guide structure 1 is connected with the conveying through hole 6.

[0021] The angle between the material guide structure 1 and the horizontal plane is a, and 8°≤a≤14°. The length of the material guide structure 1 is 0.9-1.1 m.

[0022] When the chute is used to convey the bagged cement bag 8, the bagged cement bag 8 is placed on the material guide structure 1 and enters the conveying through hole 6 at a certain speed. The bagged cement bag 8 moves along the inner wall of the conveying through hole 6 and overturns once in the upper arc segment 3 and the lower arc segment 5 respectively. Therefore, the resistance during the conveying of the bagged cement bag 8 is increased, and the speed of the bagged cement bag 8 when it comes out of the chute is effectively reduced. Under the action of the friction of the inner wall of the conveying through hole 6 and the overturning of the bagged cement bag 8, the shape and speed of the bagged cement bag 8 when it comes out of the chute are basically consistent with those when it enters the chute. The conveying of the bagged cement bag with a high drop difference is realized, which is beneficial to the continuous production of the bagged cement bag. In addition, the chute has a simple structure, occupies a small space for installation, causes less damage to the bagged cement bag 8 and can be used to convey the bagged cement bag 8 with a high height difference.

[0023] Specifically, the material guide structure 1 mainly plays a guiding role and guides the bagged cement bag 8 into the S-shaped groove body 2. The speed of the bagged cement bag 8 when it enters the chute can also be increased to ensure that the bagged cement bag 8 can be normally conveyed in the S-shaped groove body 2. Figure 1 As shown in the figure, the material guide structure 1 can be a material guide plate or a material guide groove.

[0024] In order to facilitate the processing and use of the S-shaped groove body 2, as shown in the figure, Figure 1As shown in the drawings, the upper arc segment 3 comprises a first inner side arc plate, a first outer side arc plate, a first front side arc plate and a first rear side arc plate, which are sequentially connected together, and the first inner side arc plate and the first outer side arc plate are arranged in parallel with each other, the first front side arc plate and the first rear side arc plate are arranged in parallel with each other, the first inner side arc plate and the first front side arc plate are arranged perpendicularly to each other, the diameter of the first outer side arc plate is 0.5-0.6 m, and the diameter of the first inner side arc plate is 0.2-0.3 m; the lower arc segment 5 comprises a second inner side arc plate, a second outer side arc plate, a second front side arc plate and a second rear side arc plate, which are sequentially connected together, and the second inner side arc plate and the second outer side arc plate are arranged in parallel with each other, the second front side arc plate and the second rear side arc plate are arranged in parallel with each other, the second inner side arc plate and the second front side arc plate are arranged perpendicularly to each other, the diameter of the second outer side arc plate is 0.5-0.6 m, and the diameter of the second inner side arc plate is 0.2-0.3 m. The transition segment 4 can be linear or have a certain arc.

[0025] In order to improve the service life of the upper arc segment 3 and the lower arc segment 5, the first inner side arc plate, the first outer side arc plate, the first front side arc plate, the first rear side arc plate, the second inner side arc plate, the second outer side arc plate, the second front side arc plate and the second rear side arc plate are all made of wear-resistant steel plate, and the thickness of the wear-resistant steel plate is 6-10 mm.

[0026] When the linear chute 7 is used to convey the bagged cement bag 8, only one side of the bagged cement bag 8 is in contact with the side wall of the linear chute 7, and the contact surface of the bagged cement bag 8 is damaged more seriously. In the conveying process of the present application, both sides of the bagged cement bag 8 are in contact with the inner wall of the conveying through hole 6, thereby reducing the damage to the contact surface of the bagged cement bag 8. In order to further reduce the damage to the contact surface of the bagged cement bag 8, the roughness of the inner surface of the side wall of the conveying through hole 6 is less than 3.2 μm.

[0027] As shown in the drawings, Figure 3 By arranging a plurality of S-shaped groove bodies 2, all the S-shaped groove bodies 2 are sequentially connected together from top to bottom, the number of the S-shaped groove bodies 2 is preferably 2-4, and the height of the entire chute is 2.4-8 m, so that the bagged cement bag 8 can be conveyed at a higher height difference.
