Description

Technical Field

[0001] The invention relates to the technical field of grain silo inspection, in particular to a rotating assembly for random inspection of grain silo inspection operations. Background Art

[0002] When conducting random inspections of grain inside the granary, the integrated sampling machine can be used to quickly sample and collect grain. During the grain sampling process, the angle of the cutting component after reset can be controlled by the rotating component, so as to facilitate better collection and packaging of the sampled grain. When in use, since the rotating component is in use, it is not convenient to control the sampling depth according to different sampling requirements, which affects the diversity of samples during sampling.

[0003] In order to overcome the above defects, the prior art (Chinese patent with publication number CN217786630U and application date of 2022-01-15) provides a grain silo sampling device. An air pump is fixedly installed in the inner cavity of the working box, a suction pipe is connected to the left side of the air pump, a hydraulic cylinder is fixedly installed at the bottom of the working box, a hydraulic rod is fixedly installed at the output end of the hydraulic cylinder, a suction nozzle is fixedly installed at the bottom of the hydraulic rod, a connecting frame is fixedly installed at the bottom of the working box, the right side of the connecting frame is fixedly connected to the left side of the hydraulic cylinder, and a movable wheel is movably installed on the outer surface of the connecting frame. The bottom end of the suction pipe passes through the working box and the hydraulic rod in turn and is connected to the top of the suction nozzle. By opening and fixing the fixing device, the hydraulic cylinder inserts the suction nozzle to the position where extraction is required through the hydraulic rod, and the air pump sucks out the grain through the suction pipe, and the grain at different positions is stored in different storage boxes through the valve.

[0004] The above mechanism controls the hydraulic rod to enter different depths through the hydraulic cylinder. However, in actual use, the hydraulic rod is prone to wear during the repeated extension and retraction inside the granary. At the same time, dust may enter the gap of the hydraulic rod during the resetting process of the hydraulic rod, affecting the service life of the hydraulic rod.

[0005] In order to overcome the above defects, the prior art (Chinese patent with publication number CN217179936U and application date of 2022-01-12) is a multi-point sampling device for steel plate granaries. The mounting frame is an inverted U-shaped structure, and a mounting groove is provided at the center of the mounting frame. The slide plate is slidably arranged in the mounting groove. A driving ring is rotatably plugged into one side of the top surface of the slide plate through a bearing, and a power assembly connected to the driving ring is installed on the other side of the top surface of the slide plate. A sampling tube is threadedly plugged into the driving ring. A connecting rod is fixed to the top of the sampling tube in a circular array. A mounting plate is fixed to the top of the connecting rod, and a discharge trough is provided between the multiple connecting rods. A second motor connected to the conveying assembly is provided at the top of the mounting plate, which improves the convenience of grain sampling, facilitates sampling and detection of grain at different positions and depths in the granary, and improves the applicability of the sampling device.

[0006] The above mechanism collects grains into the sampling tube by cooperating with the driving shaft and the conveying auger. However, in actual use, it is not convenient to control the sampling weight according to different needs and to identify and mark the sampling amount. Summary of the invention

[0007] The purpose of the present invention is to provide a rotating assembly for sampling in a grain silo to solve the problem in the above background technology that it is inconvenient to control the sampling depth according to different sampling requirements, which affects the diversity of samples during sampling.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a rotating assembly for sampling inspection of a grain silo inspection operation comprises an installation box, and guide belts are arranged on both sides of the installation box; A third gear is provided below the installation box, and a rotating mechanism for controlling the installation box to rotate is provided below the installation box, the installation box is arranged at the top of the fixed base, the rotating mechanism includes a second driving motor, and the second driving motor is arranged inside the fixed base, the output end of the second driving motor is fixedly connected to the fourth gear, the bottom end of the installation box is fixedly connected to the third gear, and the third gear and the fourth gear are connected through a sprocket transmission mechanism, and the output end of the second driving motor rotates and drives the fourth gear to rotate, and the fourth gear drives the third gear to rotate through the sprocket, and the third gear drives the installation box to rotate, so that the entire lifting mechanism, the cutting control box and the cutting assembly above are driven to rotate, and the cutting assembly rotates to above a suitable weighing assembly, and the staff puts a bag on the weighing assembly, and the cutting assembly puts the sampled grain into the inside of the weighing assembly, and then uses the bag inside the weighing assembly to collect the sampled material; The guide belt is symmetrical about the central axis of the installation box in the vertical direction. A lifting mechanism for controlling the height of the guide belt is arranged inside the installation box. The first gear is driven to rotate by the output end of the first driving motor, and the first gear drives the second gear to rotate through the sprocket, so that the second gear drives the threaded rod inside the installation box to rotate during the rotation. The movable block outside the threaded rod can drive the cutting control box to move up and down through the guide belt, so that the cutting assembly is driven to lift and lower, so that the bottom end of the cutting assembly gradually penetrates into the granary to sample the grain. Through the control of the lifting mechanism, the cutting assembly can be flexibly cut to the required depth according to different needs, so that the integrated inspection machine can sample grain at different depths inside the granary when sampling, thereby ensuring the accuracy of sampling.

[0009] Furthermore, a large targeting component is installed on the outer side of the fixed base through a protective component, and a weighing component is arranged on the inner side of the protective component at the top of the fixed base. There are four groups of weighing components, so when two of the weighing components are sampling, collecting and packaging, the cutting component can continue to perform sampling operations, and then the installation box is driven to rotate through the rotating component and the cutting component is controlled to be above the other two weighing components to collect samples, so that the collection operation of the staff will not conflict with the work of the entire sampling inspection machine.

[0010] Furthermore, the bottom end of the installation box is rotatably connected to the fixed base, and the installation box is arranged below the large targeting component.

[0011] Furthermore, the lifting mechanism includes a threaded rod, and the threaded rod is rotatably connected to the inside of the installation box, and the external thread of the threaded rod is connected to a movable block. By utilizing the mutual cooperation between the threaded rod and the movable block, the stability of the entire picking machine during use is increased, and the mutual cooperation between the threaded rod and the movable block makes the subsequent maintenance of the entire machine more convenient, reduces the waste of resources, and effectively extends the service life of the picking machine.

[0012] Furthermore, the movable block is slidably connected to the installation box, and the movable block extends to the outside of the installation box through the connecting block and is connected to the guide belt.

[0015] Furthermore, the implantation components are symmetrically distributed about the central axis of the installation box in the vertical direction, and the implantation components and the implantation control box are connected through a sprocket transmission mechanism and a bearing.

[0016] Furthermore, a brake assembly is fixedly connected to the top of the installation box, and the bottom end of the brake assembly passes through the installation box and is connected to the threaded rod. When the threaded rod is driven to rotate, in order to better control the operation of the threaded rod, the rotation speed of the threaded rod can be controlled by the brake assembly, thereby avoiding excessive rotation of the threaded rod, which may cause inaccurate height control of the cutting control box and the cutting assembly, and increasing the overall stability when controlling the sampling depth.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the sampling rotating assembly of the granary inspection operation adopts a new structural design, and the height and angle of the cutting assembly are controlled by the lifting mechanism and the rotating mechanism, so that the overall sampling can be more accurate. The specific contents are as follows: 1. The output end of the first driving motor drives the first gear to rotate, and the first gear drives the second gear to rotate through the sprocket, so that the second gear drives the threaded rod inside the installation box to rotate during the rotation process, and the movable block outside the threaded rod can drive the cutting control box to move up and down through the guide belt, so that the cutting assembly is driven to rise and fall, so that the bottom end of the cutting assembly gradually goes deep into the granary to sample the grain; Furthermore, through the control of the lifting mechanism, the cutting component can be flexibly cut to the required depth according to different needs, so that the integrated sampling machine can sample grains at different depths inside the granary during sampling, ensuring the accuracy of sampling; Furthermore, by utilizing the mutual cooperation between the threaded rod and the movable block, the stability of the whole picking machine during use is increased, and the mutual cooperation between the threaded rod and the movable block makes the subsequent maintenance of the whole machine more convenient, reduces the waste of resources, and effectively extends the service life of the picking machine; 2.
