Description

Technical Field

[0001] This utility model relates to the field of square balers, and in particular to a lightweight and compact carrying and traction structure for a square straw baler. Background Technology

[0002] There are two types of towing products on the market: direct towing and back-mounted towing. Direct towing has the advantage of a small turning radius and simple structure. However, it has poor passability, and when encountering large potholes, the implement often gets stuck and drags on the ground, sometimes even becoming stuck and damaged. Back-mounted towing connects the implement to the tractor's suspension. While towing, the implement's height can be adjusted at any time by controlling the back-mounted suspension angle, resulting in excellent passability. The implement's ground clearance can also be controlled for easier operation. However, due to the back-mounted towing arm, the connection distance between the tractor and the implement is increased, leading to larger turning radius during actual operation. This limits its use on small plots of land, and it only allows for horizontal turning, lacking vertical freedom. When traversing uneven surfaces, the implement and tractor may form a cross-axle, severely affecting driving comfort and causing torsional fatigue to both the implement and tractor, potentially damaging the frame or even causing a tire blowout. Summary of the Invention

[0003] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0004] To achieve the above objectives, the first aspect of this utility model proposes a lightweight and compact carrying and traction structure for a square straw baler, comprising: a machine body, a connecting groove at the bottom of one end of the machine body, a machine swing seat connected to the connecting groove, and a connecting rear component connected to the machine swing seat.

[0005] As an improvement, the tool swing base includes an intermediate connector, the upper part of which is provided with a through hole and one side is provided with a U-shaped connecting groove. A crossbar is provided in the U-shaped connecting groove, and the main body of the tool is fixed to the U-shaped connecting groove and the crossbar through the connecting groove.

[0006] As an improvement, the main body of the machine, the connecting parts and the crossbar are connected by bolts.

[0007] As an improvement, the connecting component includes a sleeve, on which a connecting rod is fitted, and at both ends of the sleeve are connecting pieces.

[0008] Beneficial effects

[0009] This simple and compact structure achieves both carrying and traction while increasing vertical freedom, perfectly solving problems related to maneuverability, turning flexibility, and driving comfort. Moreover, its simple and stable structure yields excellent practical results. It allows both the tractor and implements to rotate horizontally and vertically, adapting to various undulating and turning surfaces, reducing the reaction force of the implements on the tractor, and significantly shortening the connection distance between the tractor and implements. This reduces the turning radius, making it more flexible during transport and suitable for turning and maneuvering in small plots of land. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The following description, in conjunction with the accompanying drawings, describes the lightweight and compact backpack traction structure of the square straw bale baler according to an embodiment of the present invention.

[0017] Please see Figure 1-2 The present invention provides a lightweight and compact carrying and traction structure for a square straw baler, including a machine body 1, a connecting groove 2 at one end of the bottom of the machine body 1, a machine swing seat 3 connected to the connecting groove 2, and a connecting rear part 4 connected to the machine swing seat 3.

[0018] In this embodiment, the tool swing base 3 includes an intermediate connector 31. The upper part of the connector 31 is provided with a through hole 32, and one side is provided with a U-shaped connecting groove 33. A crossbar 34 is provided in the U-shaped connecting groove 33. The tool body 1 is fixed to the U-shaped connecting groove 33 and the crossbar 34 through the connecting groove 2. Specifically, the connecting groove 2 of the tool body 1 and the U-shaped connecting groove 33 of the connector 31 are arranged opposite to each other. The crossbar 34 passes through the connecting groove 2 and the U-shaped connecting groove 33, realizing the movable connection between the tool body 1 and the tool swing base 3, so that the tool body 1 can swing around the crossbar 34 at a certain angle to adapt to different terrains and operation requirements.

[0019] The main body 1, connecting piece 31, and crossbar 34 of the machine are connected by bolts. This connection method not only ensures the reliability of the connection but also facilitates disassembly and installation, which is beneficial for equipment maintenance and replacement of parts. During installation, the crossbar 34 is first inserted into the connecting groove 2 and the U-shaped connecting groove 33, and then the main body 1, connecting piece 31, and crossbar 34 are fastened together with bolts to ensure a firm connection.

[0020] The connecting component 4 includes a sleeve 41 on which a connecting rod 42 is fitted. Connecting pieces 43 are located at both ends of the sleeve 41. The sleeve 41 and the connecting rod 42 are connected by a sleeve-like connection, allowing the connecting rod 42 to slide within the sleeve 41, thereby adjusting the length of the connecting component 4 to accommodate different traction requirements. The connecting pieces 43 are used to connect to traction equipment such as a tractor, securing the connecting component 4 to the traction equipment via bolts or other connection methods.

[0021] The working principle of this invention is as follows: When baling of hay bales is required, the connecting piece 43 of the connecting rear piece 4 is connected to the traction device. The traction device drives the main body 1 of the implement through the connecting rear piece 4 and the implement swing seat 3. During operation, the main body 1 of the implement can swing around the crossbar 34 to adapt to changes in terrain and ensure smooth baling. At the same time, by adjusting the position of the connecting rod 42 within the sleeve 41, the length of the connecting rear piece 4 can be adjusted to meet different operational requirements.

[0022] In summary, the lightweight and compact back-carrying traction structure of the square straw baler of the present invention, through reasonable structural design, achieves reliable connection and flexible swing between the main body of the machine and the traction device. It also has the advantages of compact structure, light weight, and easy installation and disassembly, which greatly improves the working efficiency and adaptability of the square straw baler, and has significant economic benefits and practical value.
