Description

Technical Field

[0001] This utility model relates to the field of corn, and in particular to a corn chopping machine with a safety protection device. Background Technology

[0002] Corn is an important food crop, industrial raw material, and feed source, with multiple values ​​including food, economy, and ecology. It is rich in carbohydrates, dietary fiber, vitamins, and minerals. It can be eaten directly as a staple food or processed into a variety of foods. In industry, it is used to produce products such as starch and ethanol. At the same time, it is also a major feed for livestock. It has a profound impact on global food security and economic development.

[0003] Corn cutting machines are required when cutting corn into sections. However, current corn cutting machines are difficult to protect operators from damage. If the machine cannot detect the operator's position and take protective action when the operator holds the corn under the cutter, the operator's hands and arms are easily cut by the suddenly activated or out-of-control cutter. To address this problem, we propose a corn cutting machine with a safety protection device. Utility Model Content

[0004] The purpose of this invention is to provide a corn chopping machine with a safety protection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0022] Please see Figure 1-4This utility model discloses a corn slicing machine with a safety protection device, comprising a platform 1, a vertical plate 2 fixedly installed on the upper surface of the platform 1, a slicing mechanism 3 above the platform 1, two sets of sliding openings 4 on the upper surface of the platform 1, two base plates 5 fixedly installed on the bottom surface of the platform 1, a set of electric push rods 6 fixedly installed on the side of the two base plates 5 that are close to each other, and movable plates 7 fixedly installed on the telescopic ends of the two sets of electric push rods 6. The outer surfaces of the two sets of movable plates 7 are slidably connected to the inner walls of the two sets of sliding openings 4, and two clamping plates 8 are fixedly installed on the side of the two sets of movable plates 7 that are close to each other. A human displacement sensor 9 is fixedly installed on the front of the vertical plate 2, two forward and reverse motors 10 are fixedly installed on the back of the vertical plate 2, and two bearings 11 are fixedly embedded on the front of the vertical plate 2. The inner rings of the two bearings 11 are fixedly connected to transmission screws 12, and the rear ends of the two transmission screws 12 are respectively connected to the two forward and reverse motors 10. The output end of the motor 10 is fixedly installed. The outer surfaces of the two transmission screws 12 are threaded with transmission screw barrels 13. The front sides of the two transmission screw barrels 13 are fixedly connected with baffles 14. With the human displacement sensor 9 and the PLC controller 17, the two forward and reverse motors 10 drive the two transmission screws 12 to rotate in the forward or reverse direction, which can drive the two transmission screw barrels 13 and the two baffles 14 to move forward or backward. The position information of the operator can be monitored in real time and protective response can be made to block or reset the cutter 303 to prevent the equipment from starting suddenly or going out of control and causing injury to the operator, thus reducing the danger during operation. With the setting of the cutting mechanism 3, and by the two sets of electric push rods 6 pushing the two sets of moving plates 7 and the two clamping plates 8 to move closer to each other, multiple corn kernels can be fixed at the same time and cut at the same time, which improves the efficiency of corn cutting.

[0023] The cutting mechanism 3 includes a carrier plate 301, the back of which is fixedly installed on the front of the upright plate 2. A cylinder 302 is fixedly installed on the inner wall of the carrier plate 301, and a cutter 303 is fixedly installed on the telescopic end of the cylinder 302. By using the cutting mechanism 3, the cylinder 302 can be activated to work, which can drive the cutter 303 to move downward, and can cut multiple corns at the same time.

[0024] Two telescopic cylinders 15 are fixedly installed on the front of the upright plate 2. The telescopic ends of the two telescopic cylinders 15 are fixedly installed on the back of the two baffles 14 respectively. Two support legs 16 are fixedly connected to the bottom surface of the platform 1. A PLC controller 17 is fixedly installed on the back of the upright plate 2. Multiple positioning slots 18 are opened on the side of the two clamping plates 8 that are close to each other. Rectangular slots 19 are opened on the upper surface of the two baffles 14. The two telescopic cylinders 15 can assist the two baffles 14 to move back and forth and prevent the two baffles 14 from rotating. The two support legs 16 can support the equipment. The PLC controller 17 can control the equipment. The multiple positioning slots 18 can position and guide the corn. The two rectangular slots 19 can limit the cutter 303 when the equipment fails and falls.

[0025] The working principle of this utility model is as follows:

[0026] First, connect the device to a power source and monitor the operator's position in real time using a human displacement sensor 9. When the operator approaches the cutting area, the PLC controller 17 activates two forward and reverse motors 10. These motors drive two transmission screws 12 to rotate, which in turn moves two transmission cylinders 13 and two baffles 14 forward until they are below the cutter 303, blocking it and preventing sudden start-up or malfunction that could injure the operator. Next, the operator places multiple ears of corn on the platform 1 and activates two sets of electric push rods 6 to push two sets of moving plates 7 and two clamping plates 8 closer together. Simultaneously, multiple positioning slots 18 secure the ends of the corn. Then, the operator moves to the PLC controller 17. When the human displacement sensor 9 detects that the operator is moving away from the cutting area, the PLC controller 17 activates the two forward and reverse motors 10 to reset the two baffles 14 and simultaneously activate the cutting mechanism 3 to cut the multiple ears of corn at the same time.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
