Description

Technical Field

[0001] The utility model relates to the technical field of grain processing equipment, in particular to a hoist. Background Art

[0002] An elevator is a large-scale mechanical equipment that transports materials by changing potential energy. Among them, a bucket elevator is a fixed-device mechanical conveying equipment, mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials. It is widely used in feed mills, flour mills, rice mills, oil mills, starch mills of various sizes, as well as grain depots, port terminals, etc. for lifting bulk materials.

[0003] In actual applications, when the elevator is transporting grain, most of the feed ports are unable to limit the amount of grain that falls. Since the amount of grain that can be transported in the hopper is limited, some grain slides from the hopper to the bottom of the elevator and needs to be taken out and put back into the feed port. After the elevator has transported grain for a long time, a lot of dust is easily attached to the hopper. Currently, it is usually done manually by opening the equipment and wiping the hoppers one by one with a rag, which is inconvenient to clean. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The purpose of the utility model is to solve the problem that in actual applications, when the elevator is transporting grain, most of the feed ports cannot limit the falling amount of grain. Since the amount of grain that can be transported in the hopper is limited, part of the grain slides from the hopper to the bottom of the elevator and needs to be taken out and put back into the feed port. After the elevator has transported grain for a long time, a lot of dust is easily attached to the hopper. At present, it is usually necessary to manually open the equipment and wipe the hoppers one by one with a rag, which is inconvenient to clean. Therefore, a hoist is proposed.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the embodiment, Figure 1-3 A hoist is provided, comprising a shell body 1, on the outer sides of the shell body 1 are respectively provided with a feed port 2, a discharge port 3 and a debris discharge port 4, a conveyor belt 5 is arranged inside the shell body 1, on the conveyor belt 5 are installed a plurality of hoppers 6 at equal intervals, a baffle plate 7 is arranged inside the feed port 2, a driving assembly 8 for driving the baffle plate 7 to rotate is arranged on the feed port 2, an extension plate 9 is rotatably installed at the connection point between the feed port 2 and the shell body 1, a water spray assembly 10 is arranged on the top of the shell body 1, and a blast assembly 11 is arranged inside the shell body 1.

[0024] Reference Figure 1-2 , wherein the driving assembly 8 includes a driving motor 81, the driving motor 81 is fixedly installed on the outside of the feeding port 2, the output end of the driving motor 81 penetrates and extends to the inside of the feeding port 2, and is connected to the rotating rod 82, a plurality of blocking plates 7 are installed in a circular array on the outside of the rotating rod 82, and the inner width of the feeding port 2 is similar to the width of the blocking plates 7;

[0025] With the above-mentioned structural arrangement, when the grain falls, the blocking plate 7 intercepts the grain inside the feed port 2. According to the movement of the conveyor belt 5, the blocking plate 7 rotates driven by the driving motor 81, and evenly separates the grain into grain blocks of similar weight. As the grain rotates, it slides along the extension plate 9 to the inside of the corresponding hopper 6. As the hopper 6 rises, the angle of the extension plate 9 is gradually changed, and the grain that has not fallen completely in the feed port 2 is blocked until the hopper 6 rises to a certain height. The extension plate 9 loses its support and falls, and at the same time, the blocked grain slides along its surface to the inside of the new hopper 6, thereby effectively reducing the excess grain from falling to the bottom of the shell 1.

[0026] Reference Figure 1-2, wherein the width of the extension plate 9 is the same as the width of the feed port 2, and the length of the extension plate 9 extends all the way to the top of the hopper 6;

[0027] Through the above-mentioned structural setting, the same width effectively ensures that the grains do not fall when they slide down, and the extension plate 9 directly placed on the hopper 6 can ensure the accuracy of the grains falling.

[0028] Reference Figure 1-3 , wherein the water spray assembly 10 includes a water pipe 101, a water pipe 101 having one end penetrating and extending into the interior of the housing 1 is rotatably installed on the top of the housing 1, a side of the water pipe 101 located inside the housing 1 is connected to a spray head 103 through a bent hose 102, and a spring 104 is connected between the water pipe 101 and the spray head 103;

[0029] Through the above-mentioned structural arrangement, after long-term processing, the inside of the hopper 6 needs to be cleaned. At this time, the water pipe 101 is rotated, and the nozzle 103 is aimed at the direction of the hopper 6. At the same time, the water pipe 101 is connected to the external water source. Water is sprayed from the nozzle 103 along the water pipe 101 through the bent hose 102 to flush each hopper 6 driven by the conveyor belt 5. The nozzle 103 closer to the hopper 6 can ensure the cleaning effect. The existence of the bent hose 102 ensures that even if the nozzle 103 is moved by the hopper 6 due to being too close, the nozzle 103 can be reset with the cooperation of the spring 104 after the hopper 6 moves away, and the next hopper 6 is continued to be cleaned. After the cleaning is completed, the water pipe 101 is rotated, so that the transportation of the hopper 6 will not be blocked. The damping setting at the rotating position can prevent the water pipe 101 from rotating easily.

[0030] Reference Figure 1-2 , wherein the air blowing assembly 11 comprises a blower 111, the blower 111 is fixedly mounted on the outer side of the housing 1, and the air outlet of the blower 111 is connected to a ventilation pipe 112 having one end penetrating through and extending into the interior of the housing 1;

[0031] Through the above-mentioned structural setting, the blower 111 can blow down the dust and grain that may be attached to the inside of the hopper 6 through the ventilation pipe 112 when the hopper 6 transports grain, and roughly clean the hopper 6 without affecting the operation of the equipment. The water stains attached to the inside of the hopper 6 can also be dried during cleaning.

[0032] Working principle:

[0033] The first step to implement the innovation point:

[0034] Step 1: The grain enters the shell 1 along the feed port 2. After the blocking plate 7 separates the grain into multiple portions, the grain is delivered one by one to the inside of the hopper 6 through the extension plate 9 as it rotates. Then, the hopper 6 is transported by the conveyor belt 5 and pours the grain out from the discharge port 3 to complete one transportation. The fallen grain is discharged from the impurity discharge port 4 and enters the feed port 2 again after being collected.
