Description

Technical Field

[0001] The invention belongs to the technical field of grain loading and unloading, and in particular relates to grain transportation logistics loading and unloading equipment. Background Art

[0002] In the process of grain transportation, trucks are mostly used for long-distance transportation. Since grain is mostly stored on the ground when it is stored at a fixed point, and the height of the truck compartment is relatively high, a conveyor belt is used to transport the grain from the ground to the truck, and a conveyor belt is also used to transport the grain in the truck to the ground. However, when the grain is transported to the truck using the conveyor belt, the grain is thrown from the highest point of the conveyor belt into the truck compartment. In the process of gradually unloading, a grain pile will be formed in the truck, requiring staff to flatten the grain in the truck at all times. If no one is watching, the grain pile will easily become high and cause the grain to be removed from the truck. Therefore, it is very necessary to design a loading and unloading equipment that can automatically disperse the grain pile, reduce the frequency of staff dispersing the grain pile, and automatically cut off the grain loading and unloading when the grain pile is too high. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-4 As shown, a food transportation logistics loading and unloading equipment of the present invention comprises a support frame 1, a body 11 is arranged at a high and low inclination on the upper side of the support frame 1, the body 1 is equipped with a conveyor belt 12, the body 12 is equipped with a motor 13, the motor 13 is equipped with a transmission shaft 14 connected to the conveyor belt 12, a control panel 15 is arranged on the surface of the body 12, a fixed block 2 is symmetrically arranged on the higher side of the body 12, a rotating shaft 21 is rotatably connected between the two fixed blocks 2, a plurality of dispersed parts 22 are evenly arranged on the surface of the rotating shaft 21, and one end of the rotating shaft 21 extends out of the fixed block 2 and is equipped with a rotating shaft The rotating block 24 is provided with a gear ring 25 on the outer side, and the gear ring 25 is rotatably assembled on the surface of the fixed block 2. A resistance transmission mechanism is provided between the rotating block 24 and the gear ring 25, and a driving mechanism is provided between the gear ring 25 and the transmission shaft 14. The signal output end of the speed sensor 23 is signal-connected with the signal input end of the control panel 15, the power output end of the control panel 15 is electrically connected with the speed sensor 23 and the power input end of the motor 13, and the signal input end of the control panel 15 is connected with an external power supply.

[0023] When the staff needs to load and unload grain, the higher side of the lowering body 11 is located in the truck compartment, and the lower side is located on the ground. When the upper surface of the conveyor belt 12 rotates toward the truck, the staff pours the grain on the lower side of the body 11, and the grain can be transported into the truck under the action of the conveyor belt 12. When the upper surface of the conveyor belt 12 rotates toward the ground, the grain in the truck can be transported to the ground, so that the loading and unloading of grain can be realized.

[0024] When transporting grain from the ground to the truck, the motor 13 drives the gear ring 25 to rotate through the driving mechanism, and the gear ring 25 drives the rotating block 24 to start rotating through the resistance transmission mechanism, and the rotating block 24 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives a plurality of dispersing members 22 to rotate. With this design, when grain is piled up on the higher side of the machine body 1, when the upper side of the grain pile is in high contact with the dispersing member 22, since the dispersing member 22 is in a rotating state, the upper side of the grain pile is dispersed, and the grain on the upper side of the grain pile is dispersed to both sides, thereby reducing the height of the grain pile and reducing the frequency of workers leveling the grain.

[0025] When the staff has not taken care of the grain pile in the truck for a long time, and the grain pile can no longer be dispersed after being dispersed, the height of the grain pile increases, so that the grain gradually buries the dispersion member 22, and the resistance to the rotation of the dispersion member 22 gradually increases. When the resistance of the grain pile dispersion member 22 is greater than the transmission force of the resistance transmission mechanism, the gear ring 25 itself idles and will not drive the rotating block 24 to rotate, and the shaft 21 will not rotate. At this time, the speed sensor 23 detects that the shaft 21 has no rotation signal, and transmits the signal to the control panel 15. At this time, if the motor 13 is in working state, the control panel 15 stops supplying power to the motor 13. The motor 13 stops working and drives the conveyor belt 12 to stop working, thereby canceling the transmission of grain. This can prevent the grain pile from being too high and overflowing from the truck compartment.

[0026] The resistance transmission mechanism includes a plurality of arc-shaped locking members 3, which are evenly arranged on the surface of the rotating block 24 in an annular manner. A rebound assembly is assembled between the plurality of arc-shaped locking members 3 and the rotating block 24, and a plurality of arc-shaped locking grooves 31 matching the plurality of arc-shaped locking members 3 are provided on the inner wall of the gear ring 25.

[0027] When the resistance of grain to the dispersing member 22 is relatively small, the arc-shaped locking member 3 is locked into the arc-shaped locking groove 31 under the action of the rebound component, and when the toothed ring 25 rotates, it can drive the rotating block 24 to rotate. When the assist force of the grain pile dispersing component is relatively large and blocks the rotation of the dispersing member 22, the rotating block 24 will not rotate. Even if the toothed ring 25 continues to rotate, since the rotating block 24 does not rotate, the inner walls of the arc-shaped locking grooves 31 are arc-shaped and continuously squeeze the arc-shaped locking member 3 downward, and the rebound component continuously stretches and contracts to keep the arc-shaped locking member 3 always in close contact with the inner wall of the toothed ring 25.

[0028] The rebound assembly includes an extension hole 32 arranged on the surface of the rotating block 24, a mounting hole 33 is provided at the lower side of the extension hole 32, a spring 34 is assembled at the lower side of the mounting hole 33, a slider 35 is fixedly connected to the upper side of the spring 34, a connecting rod 36 is fixedly connected to the upper side of the slider 35, and the upper end of the connecting rod 36 passes through the extension hole 32 and is fixedly connected to the arc-shaped locking member 3.

[0029] When the inner wall of the arc-shaped locking groove 31 abuts against the arc-shaped locking piece 3 downward, the connecting rod 36 and the slider 35 are driven to move downward, and the spring 34 is compressed. When the arc-shaped locking piece 3 matches the next arc-shaped locking groove 31, the arc-shaped locking piece 3 is driven to extend into the arc-shaped locking groove 31 under the extension action of the spring 34, and the cycle is repeated. When the rotating block 24 cannot rotate, the gear ring 25 can still ensure rotation.

[0030] The cross sections of the extension hole 32 and the connecting rod 36 are both rectangular. Such a design of the extension hole 32 can limit the connecting rod 36, which can ensure that the connecting rod 6 is limited and the connecting rod 6 is placed to rotate.

[0031] The driving mechanism includes a gear 4 and a transmission chain 41. The center of the gear 4 is fixedly connected to the transmission shaft 14, and the gear 4 is connected to the gear ring 25 through the transmission chain 41. When the gear 4 is driven by the transmission shaft 14 to rotate, the transmission chain 41 can be driven to rotate.

[0032] The outer side of the machine body 12 is detachably equipped with a protective cover 42 that matches the transmission shaft 14, the gear 4 and the transmission chain 41, and the motor 13 is assembled on the outer side of the protective cover 42. Such a design can protect the transmission shaft 14, the gear 4 and the transmission chain 41.

[0033] The dispersing member 22 is C-shaped, and both ends of the dispersing member 22 are fixedly connected to the rotating shaft 21. Such a design can increase the dispersing area of ​​the grain.

[0034] The support frame 1 is an angle-adjustable support frame. Such a design can adjust the transmission angle of grain and adapt to trucks of different heights.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
