Abstract
Description
Technical Field
[0001] This utility model relates to the field of truck scale technology, specifically to an electronic truck scale with automatic unloading function. Background Technology
[0002] Electronic truck scales use the principle of strain gauge measurement for weighing. Strain gauges are attached to the elastic body of the weighing sensor to form a Wheatstone bridge. When there is no load, the bridge is in a balanced state and the output is zero. When the elastic body is subjected to a load, each strain gauge will produce a strain proportional to the load. The external load can be measured from the output voltage.

[0023] An electronic truck scale with automatic unloading function includes a truck scale 1, an unloading plate 4, and a motor 6. A support block 2 is fixedly connected to the surface of the truck scale 1. A protective cover 3 is bolted to the surface of the support block 2. A connecting frame 42 is fixedly connected to the surface of the unloading plate 4. An adjusting rod 41 is fixedly connected to the surface of the connecting frame 42. An adjusting sleeve 21 is movably connected to the outer surface of the support block 2, and the adjusting rod 41 passes through the surface of the adjusting sleeve 21. The motor 6 is fixedly connected to the surface of the support block 2. A gear 61 is fixedly connected to the output shaft of the motor 6. A support plate 31 is fixedly connected to the outer surface of the protective cover 3. A stop rod 33 is connected through the surface of the weighbridge 1. A connecting plate 32 is fixedly connected to the surface of the stop rod 33. A support spring 34 is sleeved on the outer surface of the stop rod 33. Through the connection between the weighbridge 1 and the support block 2, and the connection between the motor 6 and the gear 61, the control effect of the rotation of the regulating sleeve 21 on the support block 2 is achieved. With the threaded connection between the regulating sleeve 21 and the adjusting rod 41, the position of the adjusting rod 41 in the support block 2 is changed, thereby achieving the control effect of the position of the unloading plate 4 on the weighbridge 1. The motor 6 is an existing product, and its principle and connection method are existing technologies, which will not be described in detail here.
[0024] Furthermore, the cross-section of the support block 2 is L-shaped, the cross-section of the protective cover 3 is L-shaped, and the adjusting rod 41 passes through the regulating sleeve 21 and the support block 2 and is fixedly connected to the connecting frame 42. Through the connection between the support block 2 and the protective cover 3, the protective effect of the motor 6 on the support block 2 is achieved under the action of the protective cover 3. Under the threaded connection between the regulating sleeve 21 and the adjusting rod 41, the effect of regulating the length of the adjusting rod 41 on the support block 2 is achieved.
[0025] Furthermore, the adjusting rod 41 and the regulating sleeve 21 are connected by a threaded rotation. The regulating sleeve 21 is rotatably connected to the support block 2 through the motor 6 and the gear 61. Through the connection of the adjusting rod 41 and the connecting frame 42, and the connection between the connecting frame 42 and the unloading plate 4, the sliding control effect of the unloading plate 4 on the truck scale 1 is realized through the rotational connection of the regulating sleeve 21 and the adjusting rod 41, thus completing the unloading operation of the material falling from the surface of the truck scale 1.
[0026] Furthermore, gear 61 and adjusting sleeve 21 are rotatably connected by meshing tooth blocks, and the push rod 33 acts above the adjusting rod 41 through the support plate 31. Through the rotational connection of gear 61 and adjusting sleeve 21, the control operation of the rotation of adjusting sleeve 21 is completed under the action of motor 6.
[0027] Furthermore, the end of the abutment rod 33 away from the connecting plate 32 is threadedly engaged with the surface of the adjusting rod 41. The abutment rod 33 is elastically slidably connected to the support plate 31 through the support spring 34 and the connecting plate 32. Through the connection between the abutment rod 33 and the connecting plate 32, under the action of the support spring 34, the elastic sliding effect of the abutment rod 33 on the support plate 31 is achieved. Through the threaded contact between the abutment rod 33 and the surface of the adjusting rod 41, the surface of the adjusting rod 41 is cleaned, avoiding dirt on the threads of the adjusting rod 41 from affecting the control of the position of the unloading plate 4.

Through the elastic rotatable connection between the guide plate 5 and the unloading plate 4, the unloading plate 4 improves its application range and performance for unloading materials falling from the truck scale 1 under the action of the guide plate 5.
[0029] Furthermore, a through hole is provided on the surface of the fixing plate 51, and the screw 53 passes through the through hole to penetrate the surface of the fixing plate 51. The screw 53 and the screw sleeve 54 are threadedly connected. With the connection of the connecting strip 52 and the unloading plate 4, the connection of the screw 53 and the screw sleeve 54 achieves the effect of adjusting and supporting the connection angle of the guide plate 5 on the unloading plate 4.
[0030] Working principle: When unloading material from the truck scale 1, the motor 6 is started. At this time, the gear 61 drives the regulating sleeve 21 to rotate. With the threaded connection between the regulating sleeve 21 and the adjusting rod 41, the position of the unloading plate 4 in the support block 2 is changed, thereby changing the position of the unloading plate 4 on the truck scale 1, achieving the unloading effect on the surface of the truck scale 1. With the connection between the protective cover 3 and the support plate 31, and the connection between the abutment rod 33 and the support spring 34, the abutment rod 33 slides elastically on the support plate 31. With the threaded connection between the abutment rod 33 and the surface of the adjusting rod 41, the surface of the adjusting rod 41 can be cleaned. With the action of the fixing plate 51 and the connecting belt 52, and the connection between the screw 53 and the screw sleeve 54, the adjustment and support operation of the connection angle of the guide plate 5 on the unloading plate 4 is completed, improving the range and performance of the unloading plate 4 on the surface of the truck scale 1.
