Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sorting machines, and specifically relates to a corn kernel defective sorting machine. Background Art
[0002] In corn processing technology, after corn is harvested and threshed, it is necessary to sort the empty kernels from intact, full kernels to eliminate defective products and improve the quality of the finished product. Currently, corn kernel screening relies primarily on manual labor and mesh screening. During the mesh screening process, the threshed corn kernels are conveyed via a conveyor to a sorting device, where they fall directly onto the vibrating screen surface for screening. Because the intact kernels are smaller than the empty kernels, they pass through the screen smoothly and enter subsequent processing steps.
[0003] During the implementation of the disclosed technical solution, we discovered that the existing technology has at least the following problems: Operators need to regularly clean the shriveled corn kernels from the screen surface to ensure proper screening. However, this cleaning process often requires shutting down the machine and removing the filter plates, suspending the entire production line. This frequent cleaning operation seriously affects production efficiency, necessitating an urgent need for improvement. Utility Model Content
[0004] The purpose of the present invention is to provide a corn kernel defective sorting machine to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corn kernel defective sorting machine, comprising a bracket, the bracket consisting of four longitudinally arranged support rods, a lower hopper being provided at the top of the bracket, a filter being provided below the lower hopper, and the edge of the filter being connected to the inner side wall of the support rod; a support plate being provided on the side of the bracket, a first L-shaped fixing seat and a second L-shaped fixing seat being provided on the support plate, a first hinged seat being provided on the side wall of the first L-shaped fixing seat, a telescopic cylinder being hinged on the first hinged seat; a push plate being hinged at the driving end of the telescopic cylinder, the tail end of the push plate being hinged to the second L-shaped fixing seat, a connecting plate being provided on the side wall of the push plate, a brush being provided on the lower side of the connecting plate, and the bottom end of the brush being against the mesh surface of the filter.
[0006] Preferably, a shock-absorbing support is provided at the lower end of the bracket, and the number of the shock-absorbing supports is 4, and they are respectively located at the bottom ends of the 4 support rods.
[0007] Preferably, a reinforcing rod is provided between each pair of adjacent support rods.
[0008] Preferably, a vibration motor is provided on the lower side of the filter screen, the number of the vibration motors is greater than 3, and the vibration motors are arranged in a ring array around the lower end of the filter screen.
[0009] Preferably, a second hinge seat is provided on the second L-shaped fixing seat, and the second hinge seat is hinged to the tail end of the push plate.
[0010] Compared with existing technologies, the present invention offers the following advantages: by introducing an automatic cleaning mechanism, it effectively reduces the need for operators to regularly clean the screen surface of shrunken corn kernels. This improvement avoids the production line downtime caused by cleaning in traditional methods, significantly improving the overall efficiency of corn kernel screening and processing.
[0011] Traditional manual and mesh screening methods are not only inefficient but also require a high level of physical strength from the operator. This utility model, through its mechanized design, reduces the operator's workload, allowing them to focus more on other tasks. The brush ensures that shriveled corn kernels are more thoroughly removed from the filter surface during the screening process, preventing them from accumulating on the screen, thereby improving screening accuracy and effectiveness.
[0012] By arranging a shock-absorbing support at the lower end of the bracket and adding reinforcing rods between the support rods, the corn kernel defective sorting machine of the utility model is more stable and reliable during operation, and reduces noise and mechanical wear caused by vibration.
[0013] The design of the utility model allows the number and position of vibration motors, as well as the layout of push plates and brushes to be adjusted according to actual needs, thereby improving the flexibility and scalability of the equipment and enabling it to adapt to corn processing scenarios of different scales and production needs.
[0014] Since downtime and manpower input are reduced, and the durability and stability of the equipment are improved, the utility model can significantly reduce production costs and maintenance difficulty in long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-3 The present invention provides a technical solution: a corn kernel sorting machine for defective products. The device comprises a sturdy support frame 1, which is composed of four longitudinally arranged support rods, which together form the device's basic structure. A lower hopper 2 is located at the top of the support frame 1, whose primary function is to receive corn kernels to be sorted. A filter screen 3 is located below the lower hopper 2, the edges of which are tightly connected to the inner walls of the support rods, ensuring stability and reliability.
[0021] A support plate 4 is positioned laterally on the bracket 1, with a first L-shaped mounting bracket 5 and a second L-shaped mounting bracket 6 mounted on each support plate 4. A first hinged mounting bracket 7 is mounted on the sidewall of the first L-shaped mounting bracket 5, to which a telescopic cylinder 8 is hingedly attached. The driving end of the telescopic cylinder 8 is hingedly connected to a push plate 9, the rear end of which is hingedly connected to the second L-shaped mounting bracket 6, forming a flexible mechanical structure.
[0022] The push plate 9 is also equipped with a connecting plate 10 on its side, with a brush 11 mounted on its underside. The bottom end of the brush 11 rests tightly against the surface of the filter 3, ensuring that the shrunken corn kernels on the filter surface are effectively cleaned during the screening process. By introducing an automatic cleaning mechanism, this defective corn kernel sorting machine effectively reduces the need for operators to regularly clean the shrunken corn kernels from the screen surface. This improvement avoids the production line downtime caused by cleaning in traditional methods, significantly improving the overall efficiency of corn kernel screening and processing.
[0023] Traditional manual and mesh screening methods are not only inefficient but also require a high level of physical strength from the operator. This utility model, through its mechanized design, reduces the operator's workload, allowing them to focus more on other tasks. The brush ensures that shriveled corn kernels are more thoroughly removed from the filter surface during the screening process, preventing them from accumulating on the screen, thereby improving screening accuracy and effectiveness.
[0024] Specifically, the lower end of the bracket 1 is provided with a shock-absorbing support 12. There are four shock-absorbing supports 12, each located at the bottom end of each of the four support rods, to ensure the stability of the equipment during operation. A reinforcement rod is provided between each pair of adjacent support rods to enhance the overall strength and stability of the bracket.
[0025] Specifically, a vibration motor 13 is provided on the lower side of the filter 3. The number of the vibration motors 13 is greater than 3 and is arranged in a circular array around the lower end of the filter 3. This design enables the filter to vibrate during the screening process, further improving the screening efficiency and effect.
[0026] Specifically, a second hinged base 14 is mounted on the second L-shaped mounting base 6. This hinged base 14 is hingedly connected to the rear end of the push plate 9, forming a flexible mechanical connection that ensures smooth reciprocating motion of the push plate 9 during operation. This design provides greater stability during the reciprocating motion of the push plate 9, thereby improving screening accuracy and efficiency. This optimized mechanical structure enhances the stability of the equipment during operation, reduces downtime caused by equipment failure, and further improves production efficiency.
[0027] Working principle: When the utility model is working, corn kernels are put into the filter screen 3 through the lower hopper 2. The design of the lower hopper 2 is convenient for controlling the amount and speed of corn kernels to be put in, ensuring the smooth progress of the screening process.
[0028] The filter 3 is used to separate the empty kernels and other impurities from the corn kernels. The corn kernels roll and jump on the filter 3. Due to the combined effects of gravity and vibration, the full kernels are more likely to pass through the filter, while the empty kernels and impurities are retained on the filter surface.
[0029] The vibration motor 13 is mounted on the lower side of the filter screen 3 and is arranged in a circular array around the lower end of the filter screen. When the vibration motor 13 is in operation, it generates vibrations, causing the filter screen 3 to generate high-frequency micro-vibrations, which helps to separate and screen the corn kernels.
[0030] When a certain amount of deflated particles and impurities accumulate on the surface of the filter screen 3, the telescopic cylinder 8 begins to operate. The driving end of the telescopic cylinder 8 is hinged to the push plate 9, while the rear end of the push plate 9 is hinged to the second hinge seat 14 on the second L-shaped fixed seat 6. This hinge connection allows the push plate 9 to flexibly swing around the fixed point.
[0031] The telescopic cylinder 8 pushes the push plate 9 toward the filter 3, and at the same time drives the connecting plate 10 and the brush 11 to move together. The bottom end of the brush 11 contacts the mesh surface of the filter 3. As the push plate 9 moves, the brush 11 scrubs the surface of the filter, removing deflated particles and impurities from the filter surface. The removed deflated particles and impurities are discharged through the gaps or edges of the filter 3, completing the automatic cleaning process.
