[0002] In recent years, the dry farming area of the Loess Plateau in the northwest has made full use of the regional resource advantages to actively develop the Chinese medicinal material industry, and the planting area has been continuously expanding. However, the current main bottleneck lies in relying on manual excavation or traditional agricultural machinery, which leads to low efficiency and high labor intensity. Although semi-mechanized equipment such as subsoilers and rotary tillers has been widely used in the agricultural field, their application in the field of harvesting root-type Chinese medicinal materials is still insufficient and difficult to meet the growing demand of the medicinal material market. Content of the Utility Model

[0003] The purpose of the utility model is to provide a crawler self-propelled root-type Chinese medicinal material excavator, and the technical problem to be solved is to provide a crawler self-propelled root-type Chinese medicinal material excavator that can complete four processes of fork teeth forced into the soil, deep excavation, medicine soil turning, and root soil separation at one time in view of the shortcomings in the prior art, and solves the problems of low efficiency of manual excavation and high excavation cost.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A crawler self-propelled root-type Chinese medicinal material excavator includes a frame. Crawler traveling devices are arranged on both sides below the frame. An excavation execution device is arranged at the front of the frame. A controller is arranged above the frame. A starting device is arranged on the frame. A power generation device is arranged on the frame. The power generation device is linked with the starting device. A hydraulic oil tank is arranged on the frame.

[0006] Preferably, a connecting frame is arranged on the frame. A movable frame is movably connected to the connecting frame. The excavation execution device is connected to a bearing support arranged on the movable frame. Two mounting parts at the top of the excavation execution device are located on both sides at equal distances from the central axis of the frame. A second hydraulic cylinder is installed between the two mounting parts at the top of the excavation execution device. The top of the second hydraulic cylinder is connected to the movable frame. A first hydraulic cylinder is connected between the top of the connecting frame and the top of the movable frame.

[0007] Preferably, the connecting frame is arranged at the front end of the frame, and the bottom end of the connecting frame is fixed to the frame. The connecting frame is made of channel steel and is provided with a chute track. Both sides of the movable frame are provided with sliders, and the sliders of the movable frame are embedded in the inner side of the chute of the connecting frame and are adapted to the chute.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: It adopts an excavation execution device with a fork-tooth type digging shovel as the core, and a structure in which the crawler self-propelled traveling device is linked with the hydraulic system. Since the fork-tooth type digging shovel penetrates deep into the soil, has strong adaptability, and has reasonable tooth gaps, the root whiskers dug out by the fork-tooth type medicinal herb digger are relatively complete, with less root damage. Moreover, it ingeniously applies the characteristics and motion states of the hydraulic device to complete the operation of excavating medicinal herbs. At the same time, it is a crawler self-propelled rhizome type Chinese medicinal material excavator that can complete four processes of forced entry of the fork teeth into the soil, deep excavation, turning of medicinal soil, and separation of roots and soil at one time, solving the problems of low efficiency and high cost of manual excavation. This machine can not only be used for the excavation and harvesting operations of Chinese medicinal materials such as astragalus membranaceus, codonopsis pilosula, and rheum officinale, but also be suitable for the excavation and harvesting operations of seedlings after direct seeding and raising seedlings of rhizome type Chinese medicinal materials.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-10 shown, a crawler self-propelled rhizome Chinese medicinal material excavator includes a frame 1. Crawler traveling devices 2 are arranged on both sides below the frame 1. An excavation execution device 9 is arranged at the front of the frame 1. A controller 4 is arranged above the frame 1. A starting device 3 is arranged on the frame 1, and the starting device 3 is located behind the excavation execution device 9. A power generation device 10 is arranged on the frame 1, and the power generation device 10 is located on the right side of the starting device 3. The power generation device 10 is linked with the starting device 3. A hydraulic oil tank 13 is arranged on the frame 1, and the hydraulic oil tank 13 is located on the right side of the starting device 3. A transmission assembly 11 is arranged at the rear of the frame 1. A hydraulic motor 12 is connected to the surface of the transmission assembly 11 through a spline shaft. The transmission assembly 11 and the hydraulic motor 12 are linked. A hydraulic pump 14 is arranged at the lower end of the frame 1. The controller 4 is linked with the excavation execution device 9, the hydraulic oil tank 13, the hydraulic pump 14 and the hydraulic motor 12. A support device 17 is arranged at the rear of the frame 1, and the support device 17 is located at the lower rear side of the transmission assembly 11.

[0024] Each part of the frame 1 of the crawler self-propelled root Chinese medicinal material excavator is made of square tubes and corresponding specifications are selected according to the usage requirements. The parts that need safety protection are made into sheet metal outer covers. The whole machine uses the starting device 3 located in the middle of the frame 1 as the power source of the whole machine. The starting device 3 is a diesel engine and is an electric starting model. That is, the starting device 3 drives the hydraulic pump 14 to convert energy to provide power for the machine operation, and is transported to the hydraulic actuator through the hydraulic pipeline, and finally realizes actions such as fork tooth excavation and machine travel.

[0025] The crawler traveling device 2 is a set of two crawlers symmetrically distributed on both sides of the frame 1 and is used in cooperation with the transmission assembly 11. Since the transmission assembly 11 and the hydraulic motor 12 are connected by a spline shaft, the starting device 3 drives the hydraulic pump 14 to deliver power to the hydraulic motor 12 through the controller 4, realizes the energy conversion and transmits the power to the transmission assembly 11 to make the drive wheels of the crawler traveling device 2 work. Since a set of crawlers is symmetrically distributed, the whole machine moves forward and backward by the crawlers on both sides of the left and right drive wheels. Another control lever 16 is connected to the front end of the transmission assembly 11 to control the left and right steering of the whole machine, and the transmission assembly 11 has multiple gears to meet the working requirements under different usage conditions. The crawler traveling device 2 can meet the requirements of Chinese medicinal material excavation operations in hilly and mountainous areas and has a certain trafficability and climbing ability.

[0026] The starting device 3 forms a belt drive linkage with the power generation device 10 through a pulley. The hydraulic pump 14 is located on the right side of the starting device 3. The hydraulic pump 14 forms a belt drive linkage with the starting device 3 through a pulley to convert the mechanical energy output by the starting device 3.

[0027] The controller 4 is a manual multi-way valve. A radiator 15 is provided above the rear end of the frame 1 to cool the hydraulic oil of the whole machine. The radiator 15 is linked with the starting device 3. The hydraulic oil tank 13, the hydraulic pump 14, the controller 4, the first hydraulic cylinder 5, the second hydraulic cylinder 8, the radiator 15 and the hydraulic motor 12 form a hydraulic circuit.

[0028] To realize the operation, the excavation execution device 9 needs to pass through the starting device 3, output power to the hydraulic pump 14 through the belt drive to realize energy conversion, and then transport it to the controller 4, the first hydraulic cylinder 5 and the second hydraulic cylinder 8 through the hydraulic pipeline. Through the energy conversion of the two hydraulic cylinders, the action requirements of the fork teeth connected to the second hydraulic cylinder 8 are realized. When the excavation execution device 9 works, by controlling the controller 4, the stroke change of the hydraulic rod is achieved to realize actions such as fork tooth entering the soil, excavation, soil turning, shaking, and lifting.

[0029] A connecting frame 6 is provided on the frame 1, and a movable frame 7 is movably connected to the connecting frame 6. The movable frame 7 is movably connected to the sliding groove of the connecting frame 6 through pulleys on both sides. The excavation execution device 9 is connected to the bearing support arranged on the movable frame 7. The two mounting parts at the top of the excavation execution device 9 are located on both sides of the central axis of the frame 1 equidistantly. A second hydraulic cylinder 8 is installed between the two mounting parts at the top of the excavation execution device 9, and the top of the second hydraulic cylinder 8 is connected to the movable frame 7. A first hydraulic cylinder 5 is connected between the top of the connecting frame 6 and the top of the movable frame 7. A mounting frame connected to the first hydraulic cylinder 5 is provided at the top of the connecting frame 6. One end of the first hydraulic cylinder 5 is connected to the top of the movable frame 7, and the other end is connected to the mounting frame arranged at the top of the connecting frame 6.

[0030] The connecting frame 6 is arranged at the front end of the frame 1, and the bottom end of the connecting frame 6 is fixed to the frame 1. The connecting frame 6 is made of channel steel and is provided with a slide track. Both sides of the movable frame 7 have sliders. The sliders of the movable frame 7 are embedded in the inner side of the slide groove of the connecting frame 6 and adapt to the slide groove. The connecting frame 6 and the movable frame 7 are in two planes. There is a relative displacement between the connecting frame 6 and the movable frame 7 and is limited by the stroke of the first hydraulic cylinder 5. The fork tooth part of the excavation execution device 9 is an integral whole and the fork tooth is not removable. The excavation execution device 9 is connected to the bearing support provided on the movable frame 7 and the excavation execution device 9 flips outward around the bearing support. The flipping angle of the excavation device has a certain range and is limited by the stroke of the second hydraulic cylinder 8.

[0031] Working principle: When the machine is operating, the fork-tooth excavator uses the electric starting device 3 to provide power output. On the one hand, the belt drive drives the generator 10 to connect the radiator 15 to dissipate heat for the entire hydraulic system. On the other hand, it is driven by the belt to the hydraulic pump 14 to realize energy conversion, and then transmitted to the controller 4, the excavation execution device 9, and the crawler walking device 2 through the hydraulic pipeline. When the machine is operating, it moves to the designated area of the plot and engages the reverse gear. On the one hand, the controller 4 manual valve is used to operate the unit to perform step-by-step excavation operations. On the other hand, the controller 4 is used to manually operate the excavation execution device 9 to excavate Chinese medicinal materials such as astragalus and codonopsis within the working range. If the plot is relatively solid, the rear support device 17 can be manually inverted to provide a fulcrum for the fork-tooth excavation execution device 9, so that deeper excavation can be achieved to achieve the ideal excavation depth.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
