Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, and particularly relates to a cotton laser topping machine based on a chassis with a hinge structure. Background Art

[0002] In recent years, the cotton planting mode in China is basically one film, three ridges and six rows. Topping is the central link in cotton pruning work. By removing the top bud of the cotton, the apical growth advantage of the cotton can be eliminated, the growth of the main stem of the cotton plant can be controlled, the transportation direction of substances such as water and nutrients in the body can be regulated, and the emergence of ineffective branches can be avoided. More nutrients are supplied for the growth of reproductive organs, the waste of water and fertilizer by ineffective branches is reduced, the cotton plant can form bolls earlier, form more bolls, reduce shedding, and improve the quality of cotton, which has obvious effects of increasing production and income.

[0003] At present, the chassis of the existing cotton laser topping machine is of an integral structure. Since there are many potholes in the field, when the topping machine encounters a pothole during walking, the wheels are likely to be in a suspended state, thus the stability of the machine cannot be guaranteed. In severe cases, the topping machine may tip over, causing serious losses. In addition, due to many potholes in the field, the actuator of the topping machine is not in a horizontal state, thus affecting the normal operation of the actuator. Summary of the Utility Model

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows: A cotton laser topping machine based on a chassis with a hinge structure includes a first vehicle frame and a second vehicle frame located on one side of the first vehicle frame. The middle part between the first vehicle frame and the second vehicle frame is rotationally connected through a hinge shaft. Columns are arranged at both ends of the first vehicle frame and at both ends of the second vehicle frame far from the first vehicle frame. A traveling wheel is installed at the bottom of each column. A support frame is fixedly arranged at the middle part of the second vehicle frame, and a leveling platform is arranged on the upper surface of the support frame.

[0006] Preferably, through holes for passing through the hinge shaft are arranged at the middle parts of the opposite sides of the first vehicle frame and the second vehicle frame.

[0026] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a cotton laser topping machine based on a hinge structure chassis of the present utility model with reference to the accompanying drawings.

[0027] As Figures 1 - 5 shown, a cotton laser topping machine based on a hinge structure chassis of the present utility model includes a first vehicle frame 1 and a second vehicle frame 2 located on one side of the first vehicle frame 1. The middle part between the first vehicle frame 1 and the second vehicle frame 2 is rotatably connected through a hinge shaft 9. Columns 3 are provided at both ends of the first vehicle frame 1 and at the two ends of the second vehicle frame 2 away from the first vehicle frame 1. A traveling wheel 4 is installed at the bottom of each column 3. The traveling wheel 4 is driven by a hub motor, and a DC steering motor and a 63 worm and worm gear reducer for driving the traveling wheel 4 to turn are arranged in the inner cavity of the column 3. Through holes for passing through the hinge shaft 9 are provided at the middle parts of the opposite sides of the first vehicle frame 1 and the second vehicle frame 2. Both ends of the hinge shaft 9 are fixedly connected to the first vehicle frame 1 and the second vehicle frame 2 respectively through nuts. Tapered roller bearings 10 are arranged at the parts of both ends of the hinge shaft 9 located in the inner cavity of the through hole, and thrust ball bearings 11 are arranged between the middle part of the hinge shaft 9 and the first vehicle frame 1 and the second vehicle frame 2. The chassis of this topping machine is divided into two parts, namely the first vehicle frame 1 and the second vehicle frame 2. The first vehicle frame 1 and the second vehicle frame 2 are connected through the hinge shaft 9. Two pairs of tapered roller bearings 10 and one thrust ball bearing 11 are installed on the hinge shaft 9. The two ends of the hinge shaft 9 are locked with slotted nuts. This can ensure that the first vehicle frame 1 and the second vehicle frame 2 rotate and deflect relative to each other by an angle. When the chassis is walking, when encountering a small pit or a small slope, by deflecting an angle between the first vehicle frame 1 and the second vehicle frame 2, it can be ensured that at least three traveling wheels 4 of the chassis are in contact with the ground at the same time. When the vehicle passes through a small pit or a bumpy road section, the traveling wheels 4 can keep in contact with the ground to ensure stability and maneuverability, and can provide additional stability and anti-rollover functions when the vehicle passes through an uneven road surface or performs a specific operation.

[0028] A support frame 12 is fixedly arranged at the middle part of the second vehicle frame 2, and a leveling platform 5 is arranged on the upper surface of the support frame 12. The leveling platform 5 comprises a support table 6 and an adjusting plate 7 located below the support table 6. The bottom of the support table 6 is connected to the upper surface of the adjusting plate 7 through six uniformly and orderly distributed electric push rods 8. Three inclination sensors distributed in a circumferential array are arranged on the surface of the adjusting plate 7. The bottom of the support table 6 is fixedly connected to the upper surface of the support frame 12 through a plurality of uniformly and orderly distributed support rods 13. The top of the electric push rod 8 is rotationally connected to the bottom of the support table 6 through a rotating shaft, and the bottom of the piston rod of the electric push rod 8 is rotationally connected to the upper surface of the adjusting plate 7 through a rotating shaft. A laser 16 is installed at the bottom of the adjusting plate 7. This laser is a mature existing technology and will not be elaborated in detail here. When the vehicle is traveling on an uneven road surface, the first vehicle frame 1 and the second vehicle frame 2 deflect by an angle, so that the above-mentioned actuator also deflects by an angle and cannot work effectively and better. Therefore, a leveling platform 5 is added on the second vehicle frame 2. When the second vehicle frame 2 and the first vehicle frame 1 deflect, the inclination sensors measure the deflection angle and then send it to the electric push rods 8 of the leveling platform 5. The electric push rods 8 correspondingly extend and shorten to level the adjusting plate 7. In this way, real-time adjustment and stable control of the platform can be achieved.

[0029] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
