Description
Technical Field
[0001] This utility model relates to the technical field of grain-blocking mechanisms, specifically to a grain-blocking mechanism for a steering conveyor with an anti-buried wheel. Background Technology
[0002] In the field of grain storage and transportation, with the vigorous development of the grain industry, higher requirements have been placed on the performance and efficiency of various conveying equipment. As a key piece of equipment in the grain transportation process, steering conveyors are widely used in grain depots, grain processing plants, and other places, undertaking the important task of transferring grain from one place to another.
[0003] During grain transportation, the wheels of steering conveyors often face the problem of being buried by grain. When a large amount of grain accumulates near the wheels during transportation, the wheels can become embedded in the grain, preventing the steering conveyor from moving or turning normally. This not only severely affects the continuity and smoothness of grain transportation operations, significantly reducing efficiency and increasing operating time and costs, but also requires operators to expend considerable manpower and time to clear the buried wheels, increasing labor intensity and difficulty. Furthermore, buried wheels can lead to equipment damage, increasing maintenance costs and downtime, and disrupting the normal operation of the entire grain storage and processing process.
[0004] Currently, some equipment uses wheels at the rear of the entire structure. While this reduces wheel burial caused by grain flow to some extent, it still has limitations and is ineffective when large amounts of grain accumulate rapidly. Other equipment uses telescopic mechanisms for long-distance grain transport, which avoids wheel burial due to grain flow to some extent, but these devices are complex, costly, and their adaptability to different working conditions needs improvement. Furthermore, some existing anti-burial measures often neglect effective grain containment, causing grain to easily scatter during transport. This not only wastes grain but also pollutes the working environment and is difficult to clean up.
[0005] Based on this, this utility model designs a grain-blocking mechanism for a steering conveyor to prevent burial. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a grain-blocking mechanism for a steering conveyor with anti-buried wheels.
[0007] The technical solution adopted to solve the above technical problems is:
[0008] A grain-blocking mechanism for a steering conveyor includes an installation assembly, on which a laser rangefinder sensor for measuring the height of the grain surface on the steering conveyor is installed, a hydraulic control module is installed, an assembly plate for assembling the device with the steering conveyor is installed, and a grain-blocking device for blocking the grain is installed on the installation assembly.
[0009] The grain-blocking device includes a grain-blocking component and an adjusting component. The grain-blocking component is connected to the adjusting component and is connected to a hinge. The adjusting component has two sets arranged symmetrically on the left and right sides and is connected to the mounting component.
[0010] The above technical solution uses a laser rangefinder to monitor the grain pile in real time, and then uses a hydraulic control module to control the adjustment component to automatically raise and lower the grain blocking component. This prevents the grain from piling up near the front wheel of the steering conveyor without manual intervention, improving work efficiency. Furthermore, the grain blocking component can be folded by hinges during the transfer time on the steering conveyor for easy transfer.
[0011] Furthermore, the mounting assembly includes a mounting frame and a mounting plate. The mounting frame is connected to the adjustment assembly. The mounting plate is fixedly mounted inside the mounting frame. The hydraulic control module is detachably and fixedly mounted on the upper surface of the mounting plate. The laser rangefinder is fixedly mounted on the upper front surface of the mounting frame.
[0012] Furthermore, the mounting frame also includes limiting posts, with two sets of limiting posts arranged symmetrically on the left and right sides. The lower end face of the limiting posts is fixedly connected to the upper end face of the front end of the mounting frame. The two sets of limiting posts cooperate with the groove formed by the upper front end of the mounting frame to support and limit the steering conveyor.
[0013] The above technical solution improves safety by using the limiting post and the groove formed at the upper front of the mounting frame to provide support and limit movement during the transfer of the steering conveyor.
[0014] Furthermore, two sets of assembly plates are symmetrically arranged on the left and right sides. The front end face of the assembly plate is fixedly connected to the rear end face of the mounting frame. Each of the two sets of assembly plates has an assembly groove, which is used to adjust the installation height during installation.
[0015] The above technical solution involves assembling the grain-blocking mechanism with two sets of assembly plates and adjusting the installation position via the assembly slot, thus improving its adaptability and making it compatible with different models of steering conveyors.
[0016] Furthermore, the grain-blocking assembly includes a main grain-blocking plate, a main reinforcing frame, a secondary grain-blocking plate, a secondary reinforcing frame, a connecting belt, and a limiting pin. The rear end face of the main grain-blocking plate is fixed to the front end face of the main reinforcing frame by welding. Two sets of secondary grain-blocking plates and secondary reinforcing frames are symmetrically arranged on the left and right. The rear end face of the secondary grain-blocking plate is fixed to the front end face of the secondary reinforcing frame by welding. Two sets of connecting belts are symmetrically arranged on the left and right. One end of the connecting belt is hinged to the middle of the upper end face of the main reinforcing frame, and the lower end face of the other end of the connecting belt is fixedly connected to the upper end face of the limiting pin. The main reinforcing frame is connected to the adjustment assembly.
[0017] The above technical solution, by setting a main reinforcing frame at the rear end of the main grain retaining plate and a secondary reinforcing frame at the rear end of the secondary grain retaining plate, ensures that the main and secondary grain retaining plates will not deform during long-term use and maintain their durability. During the grain storage operation, the adjustment component controls the main grain retaining plate, main reinforcing frame, secondary grain retaining plate, and secondary reinforcing frame to automatically descend and contact the ground, preventing grain from accumulating on the front wheels and ensuring that the front wheels are not buried.
[0018] Furthermore, both ends of the main grain-blocking plate and the main reinforcing frame assembly are inclined surfaces, and the inner end of the secondary grain-blocking plate and the secondary reinforcing frame assembly is also inclined. The inclined surfaces of the two sets of secondary grain-blocking plate and secondary reinforcing frame assemblies respectively abut against the inclined surfaces of the main grain-blocking plate and the main reinforcing frame assemblies. The hinges are arranged in a rectangular four-point configuration with four sets. One set of mounting panels of the two sets of hinges on the right side is fixedly connected to the front end face of the main grain-blocking plate, and the other set of mounting panels of the two sets of hinges on the right side is fixedly connected to the front end face of the inner end of the right secondary grain-blocking plate. One set of mounting panels of the two sets of hinges on the left side is fixedly connected to the front end face of the main grain-blocking plate, and the other set of mounting panels of the two sets of hinges on the left side is fixedly connected to the front end face of the inner end of the left secondary grain-blocking plate.
[0019] Through the above technical solution, the two sets of auxiliary grain retaining plates and auxiliary reinforcing frames can be folded in front of the main grain retaining plate through hinges to facilitate the transfer by the turning conveyor. When the two sets of auxiliary grain retaining plates and auxiliary reinforcing frames are unfolded to retain grain, they are supported by contacting the inclined surfaces of the main grain retaining plate and main reinforcing frame.
[0020] Furthermore, the outer upper surface of the secondary reinforcing frame is provided with a limiting hole for use in conjunction with the insertion of a limiting pin.
[0021] With the above technical solution, the connecting belt is made of flexible material, so the limiting pin can move freely through the connecting belt. The limiting pin is inserted into the limiting hole to limit the two sets of auxiliary grain baffles and auxiliary reinforcing frame combined body.
[0022] Furthermore, the adjustment assembly includes a hydraulic cylinder and a connecting rod. The hydraulic cylinder is hinged to the upper front end of the mounting frame, and the output end of the hydraulic cylinder is hinged to the upper end of the main reinforcing frame. Two sets of connecting rods are arranged vertically, with one end of the connecting rod hinged to the front side of the mounting frame and the other end of the connecting rod hinged to the rear side of the main reinforcing frame.
[0023] The above technical solution monitors the grain pile using a laser rangefinder sensor, and then controls the hydraulic cylinder to drive the main reinforcing frame via a hydraulic control module. When the grain level is too high, the up-and-down movement of the grain-blocking component is controlled in real time according to the grain level to block the grain.
[0024] The beneficial effects of this utility model are as follows: (1) The grain pile is monitored in real time by a laser rangefinder sensor, and then the adjustment component is controlled by a hydraulic control module to achieve automatic lifting and lowering of the grain blocking component, so as to prevent the grain from piling up near the front wheel of the steering conveyor without manual intervention, thus improving the work efficiency; (2) When the steering conveyor is transferring grain, the two sets of auxiliary grain blocking plates and the auxiliary reinforcing frame are combined with the main grain blocking plate by hinges and can be folded in front of the main grain blocking plate so as to facilitate the transfer of grain by the steering conveyor.
