Description

Technical Field

[0001] The invention relates to the technical field of pit unloading, and in particular to a quantitative unloading device for a pit. Background Art

[0002] As a material storage device, the pit usually has many ways of unloading materials, but the traditional unloading methods cannot achieve quantitative unloading. In the papermaking process, unloading too much or too little papermaking raw materials at one time will affect the subsequent processes. Therefore, a unloading device is needed that can enable the pit to discharge materials continuously and quantitatively to ensure that the subsequent processes are carried out in an orderly manner. Summary of the invention

[0003] The purpose of the present invention is to provide a quantitative discharging device for a pit, which has the effect of being able to discharge materials quantitatively.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A quantitative discharging device for a pit comprises a pit body, a discharging port is arranged below the pit body, a discharging barrel is arranged below the discharging port, the pit body is located below the discharging barrel and a rotating shaft is rotatably arranged, a cylinder is coaxially arranged on the rotating shaft, at least eight feeding troughs are evenly opened on the cylinder, each of the feeding troughs is provided with a lifting plate, an elastic part is arranged between the bottom of the lifting plate and the cylinder, and a locking part is also arranged between the lifting plate and the discharging barrel, when an empty feeding trough is rotated below the discharging barrel, the locking part locks the lifting plate and the discharging barrel, and when the feeding trough is full of logistics, the locking part separates the lifting plate and the discharging barrel.

[0006] As a further configuration of the present invention, winding shafts are rotatably arranged on both sides of the lifting plate, and blocking cloth is wound on the winding shafts. Connecting grooves are opened on the two corresponding side edges of the lifting plate. The blocking cloth passes through the connecting grooves and is fixedly connected to the cylindrical part at the top of the blanking trough, and the winding shaft is connected to a driving component that drives it to rotate.

[0007] As a further configuration of the present invention, the driving assembly includes gears coaxially fixedly connected to the two ends of the winding shaft, a fixed plate is fixedly arranged between two groups of gears on the same side of the side wall of the blanking trough, racks are vertically fixed on both sides of the fixed plate, and the gears are meshed with the racks.

[0008] As a further configuration of the present invention, the locking member includes a locking plate fixedly connected to the lifting plate. When the lifting plate is located at the bottom of the material trough, the locking plate is located inside the material trough. When the lifting plate rises, the locking plate extends out of the material trough. The discharge barrel is located above the locking plate and is provided with a locking groove. The locking groove is open on the side facing the empty material trough and closed on the side facing the full material trough.

[0009] As a further configuration of the present invention, the elastic member includes a spring, and the spring is fixedly connected to the lifting plate and the cylinder respectively.

[0010] As a further configuration of the present invention, the ends of both sides of the rotating shaft are provided with insertion holes matching the blanking trough, and a cylinder is provided on the pit body. The cylinder is vertically arranged downward, and a plug rod is fixedly connected to the working end of the cylinder.

[0011] The beneficial effects of the present invention are:

[0012] During the initial operation, the rotating shaft is driven to rotate by a driving device or external force, and the rotating shaft drives the cylinder and the above blanking chute to rotate. Since there is no material in the blanking chute, the lifting plate rises to a high position under the action of the spring, and the locking plate on the lifting plate is higher than the blanking chute. When the locking plate rotates with the rotating shaft, the locking plate is transferred from the open side of the locking groove into the locking groove. When the blanking chute is aligned with the blanking barrel of the pit body, the locking plate and the locking groove are abutted to stop the rotating shaft from rotating. At this time, the cylinder can be controlled to extend downward, the insertion rod can be inserted into the insertion hole, the rotating shaft can be fixed, the blanking barrel starts to discharge materials, and the materials fall. When the material enters the chute, due to the gravity of the material, the lifting plate slowly descends and drives the locking plate to descend. When the chute is full of material, the lifting plate descends to the lowest position. At this time, the locking plate descends and is located inside the chute and separated from the locking chute. At this time, the cylinder can be controlled to contract to separate the insertion rod from the insertion hole. At this time, the shaft can rotate normally, and then the next empty chute is aligned with the discharge barrel to start unloading. The chute filled with material gradually moves downward as the shaft rotates, and the material falls out under the action of gravity. At the same time, under the action of the spring, the lifting plate can also push the material out to speed up the unloading.

[0013] Arranging blocking cloth on both sides of the lifting plate can prevent the material from falling from both sides of the lifting plate to the bottom of the lifting plate after the lifting plate is raised. The blocking cloth can support the material. At the same time, when the lifting plate rises or falls, it drives the gear to rise and fall. Under the action of the rack, the gear rotates forward or reversely, thereby driving the winding shaft to rotate forward or reversely, so that the blocking cloth is wound up when rising, and the blocking cloth is loosened when falling.

[0024] As a further configuration of the present invention, a winding shaft 31 is rotatably arranged on both sides of the lifting plate 24, and a blocking cloth 32 is wound on the winding shaft 31. The two corresponding side edges of the lifting plate 24 are provided with connecting grooves, and the blocking cloth 32 passes through the connecting grooves and is fixedly connected to the cylindrical body 22 at the top of the blanking trough 23. The winding shaft 31 is connected to a driving component that drives it to rotate.

[0025] As a further configuration of the present invention, the driving assembly includes a gear 33 coaxially fixedly connected to the two ends of the winding shaft 31, and a fixed plate 34 is fixedly arranged between two groups of gears 33 located on the same side of the side wall of the blanking trough 23. Racks 35 are vertically fixed on both sides of the fixed plate 34, and the gear 33 is meshed with the rack 35.

[0026] As a further configuration of the present invention, the locking member 26 includes a locking plate 261 fixedly connected to the lifting plate 24. When the lifting plate 24 is located at the bottom of the material trough 23, the locking plate 261 is located inside the material trough 23. When the lifting plate 24 rises, the locking plate 261 extends out of the material trough 23. The discharging barrel 12 is located above the locking plate 261 and is provided with a locking groove 262. The locking groove 262 is open on the side facing the empty material trough 23 and is closed on the side facing the full material trough 23.

[0027] As a further configuration of the present invention, the elastic member 25 includes a spring, and the spring is fixedly connected to the lifting plate 24 and the cylinder 22 respectively.

[0028] As a further configuration of the present invention, the ends of both sides of the rotating shaft 21 are provided with insertion holes 41 matching the blanking trough 23, and a cylinder 42 is provided on the pit body 1. The cylinder 42 is vertically arranged downward, and the working end of the cylinder 42 is fixedly connected with an insertion rod 43.

[0029] The working principle of this embodiment is as follows:

[0030] During the initial operation, the rotating shaft 21 is driven to rotate by a driving device or an external force, and the rotating shaft 21 drives the cylinder 22 and the above blanking chute 23 to rotate. Since there is no material in the blanking chute 23, the lifting plate 24 rises to a high position under the action of the spring, and the locking plate 261 on the lifting plate 24 is higher than the blanking chute 23. When the locking plate 261 rotates with the rotating shaft 21, the locking plate 261 is transferred from the open side of the locking groove 262 into the locking groove 262. When the blanking chute 23 is aligned with the blanking barrel of the pit body 1, the locking plate 261 and the locking groove 262 are abutted to stop the rotating shaft 21 from rotating. At this time, the cylinder 42 can be controlled to extend downward, and the insertion rod 43 can be inserted into the insertion hole 41 to fix the rotating shaft 21 and the blanking barrel can be discharged. The material starts to be discharged, and the material falls into the chute 23. Due to the gravity of the material, the lifting plate 24 slowly descends and drives the locking plate 261 to descend. When the chute 23 is full of material, the lifting plate 24 descends to the lowest position. At this time, the locking plate 261 descends and is located inside the chute 23, separated from the locking groove 262. At this time, the cylinder 42 can be controlled to contract to separate the insertion rod 43 from the insertion hole 41. At this time, the shaft 21 can rotate normally, and then the next empty chute 23 is aligned with the discharge barrel to start discharging. The chute 23 filled with material gradually moves downward as the shaft 21 rotates, and the material falls out under the action of gravity. At the same time, under the action of the spring, the lifting plate 24 can also push the material out to speed up the discharge.

[0031] The blocking cloth 32 is arranged on both sides of the lifting plate 24 to prevent the material from falling from the two sides of the lifting plate 24 to the bottom of the lifting plate 24 after the lifting plate 24 is lifted. The blocking cloth 32 can hold the material. At the same time, when the lifting plate 24 rises or falls, it drives the gear 33 to rise and fall. Under the action of the rack 35, the gear 33 rotates forward or reversely, thereby driving the winding shaft 31 to rotate forward or reversely, so that the blocking cloth 32 is rolled up when rising, and the blocking cloth 32 is released when falling.
