Description

Technical Field

[0001] The invention relates to the technical field of use of automatic loading and unloading vehicles, and in particular to an automatic cotton bale picking machine. Background Art

[0002] At present, after cotton is baled by balers, it is impossible to pick up cotton bales manually due to their large size and weight. At present, cotton fields mostly use forklifts and other loaders to pick up cotton bales and transport them with flatbed trucks. However, it requires a lot of supporting personnel and equipment. Forklifts and other loaders have low working efficiency and high equipment investment costs. They can only grab one bale at a time. The loaders have to go back and forth many times when working, which increases fuel consumption and costs. The loaders walk in the fields many times, making the loose fields become solid, which is not conducive to the cultivation of crops. Therefore, the market is in urgent need of an automatic cotton bale picking device that can reduce labor intensity, simplify the operation process, and integrate bale picking, transportation and unloading. Summary of the invention

[0003] The present invention aims at solving the problems in the prior art and provides an automatic cotton bale picking machine to reduce the labor intensity of picking operation and improve the picking efficiency.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A cotton bale automatic picking machine comprises a load-bearing vehicle body, a traction biasing mechanism, a round bale picking mechanism and a rear unloading mechanism, wherein the traction biasing mechanism is composed of a traction rod, a rotating frame, a rotating shaft and a deflection oil cylinder, the rotating frame is installed at the bottom of the load-bearing vehicle body, the rear end of the traction rod is installed in the rotating shaft on the rotating frame, the deflection oil cylinder is fixed to the side of the rotating frame, the piston rod of the deflection oil cylinder is fixed to the fixed plate on the side of the traction rod, fences are installed on the left and right sides of the load-bearing vehicle body, the round bale picking mechanism is composed of two front connecting plates, a front picking hopper and a picking auxiliary frame, the two front connecting plates are respectively fixed on both sides of the front end of the load-bearing vehicle body, the front picking hopper comprises a front fence plate and left and right side guard plates, and the front fence plate is connected to the left and right side guard plates. The left and right rotating shafts are connected to the front connecting plate, each front connecting plate is installed with a flipping cylinder, the piston rod of the flipping cylinder is connected to the corresponding side guard plate, the picking auxiliary frame has a U-shaped frame structure, the inner top of the left and right vertical beams of the picking auxiliary frame are connected to the top of the side guard plate through the rotating shaft, each side guard plate is installed with a flipping cylinder, the piston rod of the flipping cylinder is connected to the corresponding vertical beam of the picking auxiliary frame, the rear unloading mechanism includes a rear connecting plate, a rear baffle and an unloading cylinder, the left and right sides of the rear baffle are respectively connected to a rear connecting plate shaft, the rear connecting plate is fixed to the rear end side of the load-bearing vehicle body, each rear connecting plate is installed with an unloading cylinder, and the piston rod of the unloading cylinder is connected to the rear baffle.

[0006] A retractable spring sleeve is respectively installed in the middle of the left and right vertical beams of the above-mentioned material picking auxiliary frame.

[0007] A plurality of support rods are installed at the bottom of the load-bearing vehicle body, and a support rod is installed on the traction rod.

[0008] The front picking hopper and the rear baffle have fence-type structures respectively.

[0009] A supporting wheel is respectively installed on both sides of the front part of the load-bearing vehicle body.

[0010] The automatic cotton bale picking machine of the present invention is connected to the traction vehicle through a traction rod. The electromagnetic hydraulic control system of the present invention is composed of an electromagnetic valve, a circuit conversion switch, a circuit and a hydraulic cylinder and a hydraulic oil pipe. It can be used in common with the hydraulic system of the traction vehicle. The electromagnetic hydraulic control system can control six-way hydraulic pressure after integrating the three-way hydraulic output of the traction vehicle through electromagnetic conversion. The configuration requirements for the traction vehicle are reduced. The efficiency and safety of the operation are improved. The traction vehicle first brings the picker to the cotton bale on the field, and pushes the traction rod to deflect along the rotating axis of the rotating frame to the side of the load-bearing body through the deflection cylinder. After the deflection is in place, the front picking bucket is driven to flip down from the load-bearing body through the flipping cylinder on the front connecting plate, and then the picking auxiliary frame is flipped to the front side of the front picking bucket through the flipping cylinder on the side guard plate of the front picking bucket. In this way, the front picking bucket and the picking auxiliary frame just surround the cotton bale on the ground, and then the front picking bucket is driven to flip onto the load-bearing body through the flipping cylinder on the front connecting plate. The picking auxiliary frame has a telescopic adjustment function, and the length can be adjusted to complete the auxiliary picking of round bales of different sizes. The lifting function of the round bale is completed, so that the cotton bale is lifted into the load-bearing body, and then moved to the next cotton bale. The cotton bales are continuously loaded into the load-bearing body through the same operation, so as to realize the continuous loading of multiple cotton bales. The picking auxiliary frame is lifted before the round bale is picked up and put down after the round bale is picked up. Since the round cotton bales are relatively heavy, the support wheels on both sides of the front of the load-bearing body are put down during picking up to prevent the vehicle from tilting. When the load-bearing body is full, the deflection cylinder pulls the traction rod to rotate and reset, and the driving vehicle drives the picking machine to transport it to the unloading location. When unloading, it is only necessary to drive the front of the tailgate box to flip through the flip cylinder on the rear connecting plate, thereby forming a unloading port at the rear end of the load-bearing body. Finally, the front of the load-bearing body is lifted upward to tilt and unload the cotton bale.

[0011] The picking machine of the present invention realizes automatic picking, loading and unloading of cotton bales, greatly improves the loading and unloading picking efficiency of round cotton bales, reduces the labor intensity of cotton bale unloading, and has the advantages of reasonable design, easy use and high degree of automation.
