Description

Technical Field

[0001] This utility model relates to the technical field of equipment for transporting fluid solid materials, and more specifically to a device for recovering overloaded materials from a conveyor. Background Technology

[0002] When bulk grain leaves the warehouse, a conveyor belt is typically used to transport the grain from the warehouse to the truck bed. However, during transport, if the vehicle is not moving in time or the location of the conveyor's discharge point is difficult to determine accurately, some areas of the truck bed may be overloaded with grain. When the truck is moving, the grain may overflow from the truck bed, resulting in quantity loss, road pollution, and increased manual cleaning costs.

[0003] To address the above issues, the applicant has provided a mobile vehicle loading device in Chinese Utility Model Patent No. CN 218143710U, which is installed between a conveyor and a grain transport vehicle. The device includes a gantry frame, an A-channel, a B-channel, and a discharge pipe. The A-channel and B-channel are inclinedly positioned above the gantry frame. The lower middle side of the B-channel is rotatably supported on the top of the gantry frame by a bracket. The bottom of the B-channel is bent vertically downwards, and an annular turntable and a power mechanism for driving the annular turntable to rotate are provided on its outer circumference.

[0004] While the above patents have solved the problem of material accumulating on one side of the carriage, resulting in a reduced actual grain load or overflow, their structures are relatively complex and require gantry frames, occupying a significant amount of space when not in use and making them inconvenient to store. Therefore, we provide a conveyor overload recovery device. Utility Model Content

The conveyor is inclinedly mounted on one side of the cargo compartment of a grain transport vehicle. The grain suction machine is fixedly installed on the conveyor via a support frame. The traveling track is fixed to the side of the grain suction machine in a manner parallel to the horizontal plane. A traveling trolley is installed on the traveling track. The grain suction pipe consists of a flexible hose and a stainless steel pipe. One end of the flexible hose is connected to the suction port of the grain suction machine, and the other end is connected to one end of the stainless steel pipe. The other end of the stainless steel pipe is bent downward and extends into the cargo compartment of the grain transport vehicle. The stainless steel pipe is fixedly connected to the side of the traveling trolley.

[0008] In a preferred embodiment, the conveyor overload recovery device of this utility model further includes a walking drive mechanism, which includes a motor, a gear and a rack. The rack is fixedly provided on the top surface of the walking track. The motor is fixedly installed on the upper side of the walking trolley. The output shaft of the motor is connected to the gear, and the gear meshes with the rack.

[0009] In a preferred embodiment, a walking wheel is installed on the bottom side of the walking trolley, and the bottom surface of the walking track forms an arc-shaped groove for the walking wheel to travel on.

[0010] In a preferred embodiment, the conveyor overload recovery device of the present invention further includes a hopper, which is fixed on the conveyor and located below the discharge port of the grain suction machine.

[0011] Furthermore, a clearance groove is provided on the side of the hopper facing the conveying direction of the conveyor.

[0012] As can be seen from the above structural description of this utility model, compared with the prior art, this utility model has the following advantages:

[0013] This utility model discloses an overloaded grain recovery device for conveyors. A grain suction machine and a traveling track are directly installed on the conveyor, with the grain suction pipe movably mounted on the traveling track via a trolley. The entire device has a simple structure and is entirely mounted on the conveyor, occupying no additional space when not in use. When the grain in the carriage closest to the conveyor exceeds the overload limit, the conveyor stops conveying material, and the grain suction machine is activated to suck the grain from the edge of the carriage onto the conveyor via the suction pipe. When the grain in the carriage furthest from the conveyor exceeds the overload limit, the traveling trolley moves along the traveling track, bringing the suction port of the grain suction pipe to the edge of the carriage in the overloaded area, and then the grain suction machine is activated to suck the grain onto the conveyor, ensuring that grain can be recovered from the overloaded areas on both sides of the carriage. Attached Figure Description

[0015] Figure 2 This is a side view of the traveling track and traveling trolley of this utility model. Detailed Implementation

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details. Well-known components, methods, and processes will not be described in detail below.

[0017] A conveyor overload recovery device, referring to Figure 1It includes a grain suction machine 10, a grain suction pipe, a hopper 30, a traveling track 40, a traveling trolley 50, and a traveling drive mechanism. The conveyor 1 is inclined on one side of the cargo box 2 of the grain transport vehicle, and the grain suction machine 10 is fixedly installed on the conveyor 1 by a support frame 11.

[0018] Reference Figure 1 The aforementioned traveling track 40 is fixed parallel to the horizontal plane on the inclined upper side of the grain suction machine 10. A traveling trolley 50 is mounted on the traveling track 40, and the traveling trolley 50 is equipped with a traveling drive mechanism. The aforementioned suction pipe consists of a flexible hose 21 and a stainless steel pipe 22. One end of the flexible hose 21 is connected to the suction port of the grain suction machine 10, and the other end is connected to one end of the stainless steel pipe 22. The stainless steel pipe 22 is fixedly connected to the side of the traveling trolley 50, and the other end of the stainless steel pipe 22 is bent downwards and extends into the cargo compartment 2 of the grain transport vehicle.

[0019] Reference Figure 2 The aforementioned walking drive mechanism includes a motor 61, a gear 62, and a rack 63. The rack 63 is fixedly mounted on the top surface of the walking track 40. The motor 61 is fixedly mounted on the upper side of the walking trolley 50. The output shaft of the motor 61 is connected to the gear 62, and the gear 62 meshes with the rack 63. A walking wheel 51 is mounted on the bottom side of the walking trolley 50, and the bottom surface of the walking track 40 forms an arc-shaped groove 41 for the walking wheel to travel on.

[0020] Reference Figure 1 A hopper 30 is also fixed on the conveyor below the discharge port of the aforementioned grain suction machine 10 to receive the grain sucked out by the grain suction machine 10 and prevent it from falling off the conveyor 1. A clearance groove 31 is opened on the side of the hopper 30 facing the conveying direction of the conveyor to facilitate the recovery of the grain in the hopper by the conveyor 1.

[0021] When the grain in the car 2 near the conveyor 1 exceeds the limit, the conveyor 1 stops conveying materials and starts the grain suction machine 10 to suck the grain from the edge of the car onto the hopper 30 through the suction pipe.

[0022] When the grain in the carriage 2 on the side away from the conveyor 1 is overloaded, the walking drive mechanism is activated, causing the walking trolley 50 to move along the walking track 40, which drives the grain suction port of the grain suction pipe to the edge of the carriage in the overloaded area. Then the grain suction machine 10 is started to suck the grain out onto the conveyor 1, ensuring that the grain can be recovered from the overloaded areas on both sides of the carriage.

[0023] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto.
