Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically to an integrated agricultural grabbing and transporting machine. Background Technology

[0002] Agricultural baling and grabbing equipment typically refers to mechanical equipment used for grabbing and stacking.

[0003] Currently, the transportation method for bales involves using agricultural bale-grabbing equipment to move the bales into the cargo bin of a transport device, which then carries them for transport. It is clear that the existing system uses two separate devices for both the grabbing and transporting operations.

[0004] Therefore, a device combining grasping and transport operations was designed to address the shortcomings of conventional grasping and transport equipment: 1. Conventional gripping and transport equipment requires two operators to perform gripping and transport operations respectively; 2. Conventional transportation equipment is not suitable for sloping ground. Summary of the Invention

The described embodiments are only a part of the embodiments of this invention, not all of them. Without creative effort, all other embodiments based on the embodiments described in this invention are within the protection scope of this invention.

[0020] This invention relates to an agricultural grabbing and transporting integrated machine, such as... Figure 1 , Figure 2 As shown, it includes: The vehicle comprises a front frame 11 and a rear frame 12 articulated together. The front frame 11 houses a power system, a hydraulic system, and a steering system. A steering axle matching the steering system is mounted on the front frame 11, and a steering axle is located at the lower part of the front frame 11. A front wheel assembly 42, which is connected to the power system, is mounted on the steering axle. A leaf spring shock absorber is mounted on the rear frame 12, and a rear wheel assembly 41 is mounted on the leaf spring shock absorber. A cargo bin 30 is articulated on the rear frame 12, with the articulation point between the cargo bin 30 and the rear frame 12 located at their rear ends. A loading cylinder is articulated below the cargo bin 30, and the other end of the loading cylinder is articulated on the rear frame 12 and connected to the hydraulic system.

[0021] A connecting frame 13 is provided at the hinge between the front frame 11 and the rear frame 12. The connecting frame 13 is used to adjust the levelness of the rear frame 12, such as... Figure 3 , Figure 4 As shown, it includes: A front mounting base 130 is fixedly connected to the front frame 11. An upper limit seat 131 and a lower limit seat 132 protrude from the rear end of the front mounting base 130. Two sets of the upper limit seat 131 and lower limit seat 132 are provided, symmetrically arranged on both sides in the left-right direction. A main hinge seat 133 is provided in the center of the front mounting base 130. A rotating seat 134 is rotatably mounted on the main hinge seat 133. The rotating seat 134 is shaped like a cross. Steering cylinders 13 connected to the hydraulic system are hinged to the protruding parts at the left and right ends of the rotating seat 134. 5. The other end of the steering cylinder 135 is hinged to the rear frame 12. The protrusions at the left and right ends of the rotating seat 134 are located between the upper limit seat 131 and the lower limit seat 132. The protrusions at the upper and lower ends of the rotating seat 134 are fixedly provided with a rear hinge seat 136. The rear hinge seat 136 is hinged to the rear frame 12. The lower end of the rotating seat 134 extends to provide a hinge ear 137. A rotating cylinder 138 connected to the hydraulic system is hinged to the hinge ear 137. The other end of the rotating cylinder 138 is hinged to the front frame 11.

[0022] The upper end of the front frame 11 is equipped with a main rotating platform 20, such as Figure 1 , Figure 2As shown, a cab 21 and a grab arm rotating platform 22 are arranged side by side along the left-right direction on the main rotating platform 20. A control device is installed in the cab 21 and is electrically connected to the hydraulic system. A main gear ring is coaxially arranged on the main rotating platform 20, and a main rotation drive 24 is driven on the main gear ring. A grab arm gear ring is coaxially arranged on the grab arm rotating platform 22, and a grab arm rotating drive 25 is driven on the grab arm gear ring. A grab arm 23 is arranged on the grab arm rotating platform 22, and the hydraulic drive cylinder of the grab arm 23 is connected to the hydraulic system. The main gear ring and the grab arm gear ring are annular gear rings, and the tooth surfaces of the two are respectively arranged on the inner wall of their respective annular gear rings. The main rotation drive 24 and the grab arm rotating drive 25 are respectively hydraulic motors connected to the hydraulic system.

[0023] Based on the specific structure of the agricultural grabbing and transporting machine in the above embodiments, its working method will be further explained below: A. Picking up and transporting goods: By controlling the main rotation drive 24, the main rotation platform 20 is rotated as a whole, so that the cab 21 faces forward. The grab arm rotation drive 25 is operated to adjust the position of the grab arm 23, and the grabbing handle at the end of the grab arm 23 grabs the bundle. The main rotation drive 24 is operated to rotate the main rotation platform 20 as a whole, so that the cab 21 faces backward, and the grabbing handle of the grab arm 23 grabs the bundle and places it on the cargo bin 30. By controlling the main rotation drive 24 to rotate the main rotation platform 20 as a whole, the cab 21 is made to face forward, and the vehicle is driven for transportation.

[0024] B. Unloading: Using the control device, the unloading cylinder is manipulated to lift the cargo bin 30, and the bundles on the cargo bin 30 slide to the ground behind.

[0025] By controlling the main rotary drive 24 to rotate the main rotary platform 20 as a whole, the cab 21 faces the rear, and the grabber at the end of the grab arm 23 grabs the bundles on the cargo bin 30. By controlling the main rotary drive 24 to rotate the main rotary platform 20 as a whole, the grabber grabber 23 places the bundles on the side ground.

[0026] C. Horizontal adjustment: When the rear frame 12 is on the ground that is tilted in the left and right direction, the rotating cylinder 138 causes the rotating seat 134 to rotate along the central axis of the rotating seat 134, so that the front frame 11 and the rear frame 12 rotate along the central axis of the rotating seat 134, ensuring that the cargo box 30 is horizontal. The upper limit seat 131 and the lower limit seat 132 limit the protrusions at the left and right ends of the rotating seat 134 to prevent the front frame 11 and the rear frame 12 from rotating excessively.

[0027] D. Turning: like Figure 5 As shown, by means of a control device, the left and right steering cylinders 135 are operated in opposite directions, causing the front frame 11 and the rear frame 12 to rotate along the central axis of the rear hinge seat 136; in this state, the wheel axle angle between the front wheel assembly 42 and the rear wheel assembly 41 is the first steering angle 51, and the first steering angle 51 is up to 30°.

[0028] like Figure 6 As shown, with the front frame 11 and rear frame 12 rotating along the rear hinge seat 136, the steering axle is operated to drive the front wheel assembly 42 to rotate. In this state, the wheel axle angle between the front wheel assembly 42 and the rear wheel assembly 41 is the second steering angle 52, which has a maximum value of 50°. The steering pump and steering cylinder 135 of the steering axle are connected to the hydraulic system via a distribution valve to ensure consistent steering. When the steering pump is at its maximum angle, the front wheel assembly 42 shares a common center point with the rear wheel assembly 41 in the form of an Ackermann angle.

Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept.
