[0002] After searching the Chinese patent document with the existing announcement number CN207978353U, a ground profiling orchard mower is disclosed, which includes a frame, a transmission device and a mowing unit. The transmission device and the mowing unit are both arranged on the frame. The number of the mowing units is more than two. The mowing unit includes a flexible shaft, a rotating frame, a terrain wheel and a cutter disc. One end of the flexible shaft is connected to a multi-axis device, and the other end is connected to a cutter disc shaft. One end of the rotating frame is hinged to the rear end of the frame through a rotating shaft, and a terrain wheel is arranged below the other end. The arrangement direction of the rotating frame is perpendicular to the forward direction of the mower. The cutter disc is installed below the rotating frame through the cutter disc shaft. The sequential connection line of the cutter disc shafts of multiple cutter discs forms a sawtooth shape. The external driving device is used to drive the cutter disc to rotate and drive the mower forward by driving the transmission device to mow the grass. The device has a simple structure and is easy to operate. It can not only perform profiling in the forward direction of the mower, but also perform profiling in a direction perpendicular to the forward direction of the mower. The profiling range is more comprehensive and the efficiency is higher.

[0003] my country's orchard industry is developing rapidly. Due to the terrain, the comprehensive mechanization level in hilly and mountainous areas, which are the main fruit producing areas, is only 5.75%. Most operations are completed manually, which seriously restricts the development of the orchard industry. Orchard weeds seriously affect the growth quality of fruit trees, and weeding has become an important operation link. With the promotion of the orchard grass planting model, the intensity of orchard weeding has greatly increased. Orchards in hilly areas are restricted by the terrain of the garden. The ground in the garden is undulating, and it is difficult for existing large mowers to enter. Mechanized mowing is difficult, and manual mowing is mostly used, which is costly and inefficient. Existing small crawler mowers can mow on complex ground in hilly orchards, but due to the undulating changes in the ground, the mowing device cannot maintain the consistency of the cutting height, and the ground cannot be fed back in time. The angle of weed cutting varies greatly, resulting in missed cutting, tool contact with the soil, and increased power consumption. Utility Model Content

[0036] Specifically, the structure is composed of a frame 1, a height adjustment tube 2, a profiling wheel 3, a cutting disc 4, a mowing motor 5, a side sliding baffle 6, a front connecting frame 7, an inclination adjustment device 8, an ups and downs device 9, a horizontal connecting rod 10, a rear connecting frame 11, a damping rod 12, a cutting disc 13, a sliding cutting blade 14 and a grass divider 15 to form a hilly orchard profiling mower. The rear part of the frame 1 is connected to the front lower part of the quadrilateral connecting rod ups and downs device 9 through two rotating connecting pieces, and the front end of the frame 1 is connected to the upper part of the front end of the ups and downs device 9 through the inclination adjustment device 8. The inclination adjustment device 8 can form a triangular stable structure with the frame 1 and the front of the ups and downs device 9 in a fixed state. The frame 1 has a cutting disc 4 installed below, and two mowing motors 5 are installed horizontally in the middle of the cutting disc 4. The mowing motors 5 are powered by a lithium battery placed on a crawler traction trolley. The mowing motors 5 are connected to the cutting disc 13. Each cutting disc 13 is equipped with three sliding cutters 14. The sliding cutters 14 installed on the two cutting discs 13 are in opposite directions, and the mowing motors 5 providing power also rotate in opposite directions, so that the weed debris after cutting is conveniently discharged from the middle and rear of the cutting disc 4. A side sliding baffle 6 is welded below the left and right sides of the cutting disc 4 to protect and prevent the blades of the sliding cutters 14 from hitting the soil and colliding with the blades, so as to assist the ground profiling cutting operation. The hilly orchard profiling mower can be used for cutting and slicing. The rear connecting frame 11 in the undulating device 9 is vertically fixedly connected to the crawler traction trolley, and its degree of freedom is 0. Four horizontal connecting rods 10 of equal length connect the rear connecting frame 11 and the front connecting frame 7 through a rotating hinge to form a parallelogram structure, so that the front connecting frame 7 always remains vertical. Two damping rods 12 connect the rear connecting frame 11 and the frame 1 below the front connecting frame 7, which can slow down the sudden change in speed of the lawn mower during the up and down contouring and undulating operation, thereby protecting the mechanism. The contouring device includes a height adjustment tube 2 and a contouring wheel 3. The height adjustment tube 2 can be divided into an inner tube and an outer tube. The inner tube is welded to the top of the contouring wheel 3, and the outer tubes of the three groups of height adjustment tubes 2 are It is welded to the front end of the frame 1 and arranged horizontally equidistantly to ensure the reliability of the profiling device. The relative positions of the inner and outer tubes of the height adjustment tube 2 are controlled by a latch to adjust the height of the profiling wheel 3 and control the required cutting height. The inclination adjustment device 8 is essentially a telescopic rod. The length of the front connecting frame 7 is fixed and always remains in a vertical state. When the length of the frame 1 is fixed, the length of the inclination adjustment device 8 can be adjusted to change the angle between the frame 1 and the ground. The cutting disc 4 is installed under the frame 1. The change in the inclination angle of the frame 1 causes the angle between the cutting disc 4 and the ground to change, resulting in a change in the cutting inclination angle of the mower, so that the overall practicality of the hilly orchard profiling mower can be effectively improved.

[0037] Working principle: The lithium battery located in the crawler traction trolley provides power to the mowing motor 5 on the cutting disc 4. The mowing motor 5 converts the power into mechanical energy and starts to rotate, driving the cutting disc 13 below to rotate. The sliding cutter 14 is affected by the rotation of the cutting disc 13 and rotates accordingly. The two cutting discs 13 rotate in opposite directions, which is convenient for discharging weeds from the middle position of the cutting disc 4 backwards. When the swinging blade collides with objects such as stones, it can be rebounded to reduce the damage to the blade. Before operation, the hilly orchard mower can adjust the telescopic length through the inclination adjustment device 8 according to the type of weeds in the orchard, thereby changing the cutting angle of the blade when cutting the weeds. When performing ground profiling, the profiling device first receives ground undulation information, and the undulation device 9 passively responds to the ground undulation information. The rear connecting frame 11 is fixed to the crawler traction trolley, and the front connecting frame 7 moves to drive the lawn mower to perform up and down profiling operations to ensure the consistency of the mowing height of the lawn mower. The damping rod 12 in the undulation device 9 can reduce the speed mutation phenomenon in the undulation to a certain extent. When the cutting disc 4 moves with the ground undulation, the side sliding baffles 6 on both sides can prevent the cutting disc 13 from colliding with the ground and assist in the profiling cutting operation. The weed divider 15 can keep the weeds upright when entering the cutting disc 4 for easy cutting.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
