[0004] The utility model is implemented as follows: it comprises a material guide box, a belt is arranged at the bottom of the material guide box, a feed chute and a dust cover are arranged at the top of the material guide box, a cylinder is also arranged at the top of the material guide box, the cylinders are symmetrically arranged in two, the piston rods of the cylinders face the outside of the material guide box, and the free ends of the piston rods are respectively hinged with openable and closable sealing mechanisms; the sealing mechanisms are symmetrically arranged, and the two symmetrically arranged sealing mechanisms are abutted by the piston rods and maintained inside the side wall of the material guide box.

[0005] Furthermore, the sealing mechanism includes a push rod having one end hingedly connected to the piston rod, and the other end of the push rod is vertically fixed to one end of a connecting rod; the other end of the connecting rod passes through the end wall of the material guide box and extends into the material guide box, and the connecting rod is fixedly connected to an upper material baffle plate in the box body; the lower side of the upper material baffle plate is hingedly connected to a lower material baffle plate, and the lower end of the lower material baffle plate extends toward the belt direction; the side wall of the lower material baffle plate is hingedly connected to a support rod, and the other end of the support rod is hingedly connected to the side wall of the material guide box.

[0006] Furthermore, a protective skin is fixedly connected to the lower side of the lower material baffle plate via a fastener, and the lower end of the protective skin extends to the belt. When the sealing mechanism is in a sealing state, the lower end of the protective skin abuts against the belt.

[0007] Furthermore, the included angle between the push rod and the upper baffle plate is 131±1 degrees.

[0008] Furthermore, the cylinder is fixedly arranged on a cylinder base, and the cylinder base is fixedly connected to one end of the top of the material guide box. A cylinder base rib is fixedly connected to the lower surface of the cylinder base and one end of the material guide box, and the cylinder base rib is used to support and fix the cylinder base.

[0009] Furthermore, the hinged connection is configured as a hinge connection.

[0010] Furthermore, the dust removal hood is provided with a regulating valve for adjusting the dust removal air volume.

[0011] The utility model has the advantages and technical effects: the utility model forms a double-layer closed cover at the belt drop point, has better sealing performance, and avoids the spillage of drop dust.

[0012] The dust sealed in the material guide box is sucked into the dust hood and connected to the dust removal system through the dust removal pipe connected to the dust removal hood.

[0013] The utility model forms a double-layer closed cover at the belt unloading point, which has better sealing performance and prevents dust from overflowing when the material is unloaded. The inner closed baffle is an adjustable baffle, which can be opened during non-unloading time by being controlled by a cylinder to prevent materials transported from the previous unloading point from being blocked by the inner baffle and causing belt accidents.

[0014] Since a dust hood is provided on the material guide box, the dust generated by the falling materials and the disturbance of the air flow will diffuse along the conveying direction of the belt. Only a small amount of dust removal wind is needed to absorb the dust generated by the falling materials through the dust removal hood, thus saving the dust removal air volume.

[0015] An adjusting valve is provided on the dust collecting hood to adjust the dust collecting air volume to a suitable level so that the dust collecting hood only absorbs dust but not materials, thus saving dust collecting air volume and avoiding material waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figures 1 to 3 A double-layer closed material guide box device includes a material guide box 2, a belt 12 is arranged at the bottom of the material guide box 2, and the material guide box 2 is arranged at the material dropping point of the belt 12 to prevent dust caused by material dropping.

[0022] A feed chute 8 is provided on the top of the material guide box 2, and the feed chute 8 is used to transport materials to the belt; a dust removal hood 1 is also provided on the top of the material guide box 2, and the dust removal hood 1 can absorb the dust generated by the unloading of materials. Since a sealing mechanism 14 is provided in the material guide box 2, a double-layer seal is formed to achieve a better sealing effect. The dust generated by the unloading of materials and the air flow disturbance of the unloading of materials diffuse along the belt transportation direction. Therefore, only a small amount of dust removal wind is needed to suck the dust into the dust removal hood 1, saving the dust removal air volume.

[0023] A cylinder base rib plate 4 is provided at one end of the material guide box 2 extending to the outside of the material guide box 2 , and a cylinder base 5 is fixedly connected to the cylinder base rib plate 4 . The cylinder base rib plate 4 is used to support the cylinder base 5 , and the cylinder base 5 is fixedly connected to the cylinder 3 .

[0024] The cylinders 3 are symmetrically arranged in two, and the piston rods 13 of the cylinders 3 are respectively facing the outside of the material guide box 2, and the free ends of the piston rods 13 are respectively hinged with openable and closable sealing mechanisms 14, and the sealing mechanisms 14 are symmetrically arranged.

[0025] The sealing mechanism 14 includes a push rod 6 , one end of which is hinged to the piston rod 13 , and the other end of which is vertically fixed to one end of a connecting rod 18 .

[0026] The other end of the connecting rod 18 passes through the end wall of the material guide box 2 and extends into the material guide box 2. A matching hole is provided on the end wall to allow the connecting rod 18 to pass through. The matching hole is set to a longitudinal oblong shape. The connecting rod 18 can move up and down in the oblong matching hole to provide support for the upper push rod 6 and the upper material baffle plate 9 to rotate coaxially around the connecting rod 18; the connecting rod 18 is fixedly connected to the upper material baffle plate 9, the angle between the push rod 6 and the upper material baffle plate 9 is 131±1 degrees, the width of the upper material baffle plate 9 is set to 220mm, and the lower side of the upper material baffle plate 9 is hinged to the lower material baffle plate 7 by a hinge 10; the lower material baffle plate 7 is hinged to one end of the support rod 11 by the hinge 10 at 250mm downward from the hinge point, the length of the support rod 11 is 210mm, and the other end of the support rod 11 is hinged to the side wall of the material guide box 2, and the hinge point is 351mm downward from the matching hole in the side wall.

[0027] The lower side of the lower baffle plate 7 is fixedly connected with a protective skin 17 by bolts 15. The bolts 15 pass through the lower baffle plate 7 and the protective skin 17 in sequence, and then press the pressing plate 16, which is then locked by a nut. The lower end of the protective skin extends to the belt, and when the sealing mechanism 14 is in a sealing state, the lower end of the protective skin abuts against the belt.

[0028] The lengths of the upper material baffle plate 9 , the lower material baffle plate 7 and the protective skin 17 are consistent with the length of the side wall of the material guide box 2 , so as to form a double-layer sealing effect of the side wall of the material guide box 2 .

[0029] Furthermore, a regulating valve is provided on the dust hood 1, which can adjust the dust removal air volume to just inhale the dust without accidentally inhaling the material, thereby saving the dust removal air volume and avoiding material waste.

[0030] The working principle of the utility model is described below:

[0031] The double-layer sealed material guiding box device comprises a sealing mechanism 14 arranged inside the side wall of the material guiding box 2, and the sealing mechanism 14 is controlled by a cylinder.

[0032] When material is not being unloaded, the cylinder 3 is opened to extend the piston rod 13. Since the other end of the push rod 6 connected to the piston rod 13 is fixedly connected to the connecting rod 18, and the connecting rod 18 is controlled by the matching hole on the end wall of the material guide box 2, the connecting rod 18 can only rotate a certain angle in the matching hole; the other end of the connecting rod 18 is fixedly connected to the upper material baffle plate 9, and the upper material baffle plate 9 rotates simultaneously with the connecting rod 18; the lower side of the upper material baffle plate 9 is connected to the lower material baffle plate 7 by a hinge 10, and the lower material baffle plate 7 is hingedly connected to the inner surface of the side wall of the material guide box 2 by the support rod 11. Therefore, as the upper material baffle plate 9 rotates, the lower material baffle plate 7 is lifted around the support rod 11; opening the sealing mechanism 14 during non-unloading time can prevent the material transported from the upper unloading point from being blocked by the protective skin 17 connected to the lower end of the lower material baffle plate 7, causing a belt accident.

[0033] When unloading, the air cylinder 3 is opened to retract the piston rod 13, and the piston rod 13 drives the upper baffle plate 9 and the lower baffle plate 7 to restore the sealing position.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
