Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to agricultural machinery equipment field, concretely relates to a corn thresher hoist lift alarm device. BACKGROUND
[0002] When the corn thresher is working, the corn is lifted by the hoist from the bottom of the cleaning screen outlet to the top through the scoop, and then the corn kernels are loaded into the car through the grain outlet. The prior art such as the "grain lifting machine device with automatic turnover feeding hopper guardrail" shown in the announcement number CN212798273U. The hoist device of the existing corn thresher is placed parallel on the top of the machine body before work, and needs to be erected and connected with the middle transmission part before the threshing work can be carried out. SUMMARY
[0003] The utility model provides a corn thresher hoist lift alarm device according to the existing condition, realizes the automatic warning function by combining with the structure and working state of the corn thresher, can effectively remind personnel to stay away from the action area, improves the safety of the threshing work, can effectively avoid the occurrence of personal injury accidents, has good practicality and market promotion value.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A corn thresher hoist lift alarm device, comprising a hoist on a corn thresher, a rack and a protective fence matched with the hoist; an infrared sensing device for human body sensing is installed on the rack and / or protective fence, a control module receives the infrared sensing device signal and the hoist working state for signal processing, and the control module is connected with a warning device.
[0006] The scheme of the utility model can also be:
[0007] The infrared sensing device is installed around the rack and / or protective fence at an interval of 0.5 to 3 meters.
[0008] The control module starts the safety area detection in the hoist lifting working state.
[0009] The warning device is an audible and visual warning device.
[0010] The warning device independently warns according to different safety areas.
[0011] The utility model discloses a corn thresher elevator lift alarm device, during the lift of elevator, automatic warning operator and surrounding personnel, remind personnel to stay away from this action area, improve the safety of operation, have good practicality and market promotion value. BRIEF DESCRIPTION OF DRAWINGS
[0012] Figure 1 The utility model discloses a corn thresher elevator lift alarm device, through the combination with the mechanism of corn thresher and the operation process realizes automatic warning function, can effectively remind personnel to stay away from this action area, improves the safety of the threshing operation, effectively avoids the occurrence of personal injury accident, has good practicality and market promotion value. DETAILED DESCRIPTION
[0013] The utility model discloses a corn thresher elevator lift alarm device, through the combination with the mechanism of corn thresher and the operation process realizes automatic warning function, can effectively remind personnel to stay away from this action area, improves the safety of the threshing operation, effectively avoids the occurrence of personal injury accident, has good practicality and market promotion value.
[0014] As shown in the drawings, a corn thresher elevator lift alarm device, including the elevator 1 of corn thresher, and the rack 2 and the protective fence 3 of the cooperation of elevator 1, on the rack 2 and / or protective fence 3 install human body response infrared sensing device 4, control module 5 receives infrared sensing device 4 signal and the signal processing of elevator 1 working state, control module 5 is linked with warning device.
[0015] The infrared sensing device 4 of the application is installed around the rack 2 and / or protective fence 3 with a spacing of 0.5 to 3 meters, forming a three-dimensional monitoring, which can quickly monitor the personnel within 3 meters around the elevator 1, and the infrared sensing device 4 has rapid emission and reception response, with a response time of milliseconds, and can monitor the working area in real time.
[0016] The infrared sensing device 4 adopts a three-dimensional monitoring around, and the corresponding warning device independently warns according to different safety areas. Through the signal triggering sequence of different area sensors, the control module 5 can judge the direction and position of the personnel, and display the direction information synchronously when alarming, which is convenient for the operator to respond accurately.
[0017] The warning device is an audible and visual warning device, and the warning modes such as voice broadcast and flashing significantly improve the warning effect. Even in a noisy working environment, the operator and the surrounding personnel can also timely perceive the danger and reduce the accident rate.
[0018] The control module 5 can start the safety area detection in the lifting working state of the elevator 1 through the limit switch of the elevator 1 or the operation circuit of the corn thresher, to prevent false honking.
[0019] The utility model discloses a corn thresher elevator lift alarm device, through the combination with the mechanism of corn thresher and the operation process realizes automatic warning function, can effectively remind personnel to stay away from this action area, improves the safety of the threshing operation, effectively avoids the occurrence of personal injury accident, has good practicality and market promotion value.
