Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and specifically refers to a new type of electric agricultural machinery power battery mounting, fixing and heat dissipation structure. Background Technology

[0002] Agricultural machinery (hereinafter referred to as "agricultural machinery") refers to various mechanical equipment used in agricultural production and related processes, including tractors, seeders, harvesters, and plant protection drones, aiming to improve agricultural production efficiency, reduce labor intensity, and ensure food security. Currently, agricultural machinery has become a core force driving the high-quality development of modern agriculture.

[0003] With the continuous development of new energy vehicles, modern agricultural machinery is also increasingly adopting electricity as its driving force, and electric tractors are becoming a future development trend. For example, Chinese patent application publication number CN114271046A discloses an agricultural rotary tiller, including: a tractor, a rotary tilling mechanism, and a traction mechanism for connecting the tractor and the rotary tilling mechanism. The tractor includes: a tracked main body and a traction motor mounted on the tractor to drive the track drive wheels. The rotary tilling mechanism includes: a base, a cutter shaft mounted on the base, and a rotary tilling motor for driving the cutter shaft. Rotary cutters are distributed along the axial direction on the cutter shaft. The traction mechanism uses a movable linkage mechanism to movably connect the rotary tilling mechanism to the tractor. A support mechanism is also provided on the rotary tilling mechanism to support it. This invention, through reasonable design, improves the balanced distribution of traction force and overcomes the problem of uneven force caused by the rotary tilling mechanism's own weight or uneven ground. At the same time, the rotary tillage mechanism maintains balance and stability during operation, ensuring that the tillage depth remains consistent.

[0004] Since agricultural machinery needs to work for long periods of time, and electric tractors often carry batteries with limited energy storage, they need to be charged or replaced in a timely manner. However, direct charging requires the tractor to stop and wait, which affects agricultural production. How to quickly and efficiently replace batteries is one of the future development directions of agricultural machinery.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content

[0010] Furthermore, in the above technical solution, the battery module, control unit, and drive assembly are arranged sequentially from front to back on the vehicle frame. The front of the vehicle frame is provided with a front compartment for mounting the battery module and control unit, and the rear of the vehicle frame is provided with a rear compartment for mounting the drive assembly.

[0011] Furthermore, in the above technical solution, the front end face of the front compartment is provided with a number of grid holes, the front end of the frame is provided with an insect-proof cover covering the grid holes, and an inner grid plate located between the vertical slot plates and distributed alternately with the grid holes is installed inside the front compartment.

[0013] Furthermore, in the above technical solution, the partition between the front compartment and the rear compartment is provided with heat dissipation holes, and the partition is provided with a fan for generating airflow, which is located on one side of the heat dissipation holes.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the present invention, a fixing strip is used to press the battery module and limit it to the frame.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] As shown in the figure, a novel electric agricultural machinery power battery mounting, fixing, and heat dissipation structure is provided, including a tractor A. The tractor A has a drive assembly D, a battery module E, and a control unit F mounted on its frame A1. The battery module E is mounted and fixed in the frame A1 by at least two fixing plates A2. The frame A1 is provided with a vertical groove plate A3 and a bolt rod A4 for connecting the two ends of the fixing plates A2. One end of the fixing plate A2 is fastened to the vertical groove plate A3, and the other end of the fixing plate A2 is locked to the bolt rod A4 by a nut A5. A fixing plate A2 is used to press the battery module E onto the frame A1, limiting its position. One end of the fixing plate A2 hooks onto the vertical slot plate A3, and the other end is locked to the bolt rod A4 by the nut A5, thus achieving quick assembly. When replacing the battery module E, simply unscrew the nut A5 to remove the fixing plate A2, completing the quick replacement of the battery module E. This avoids the need for reverse-locking when disassembling and assembling the battery module E, greatly improving the working efficiency of agricultural machinery.

[0022] The upper end of the vertical slot plate A3 is provided with multiple mounting slots A31 for fastening the fixing strip A2. The end of the fixing strip A2 is bent into a first hook portion A21 that can be installed in the mounting slots A31. By providing multiple mounting slots A31 on the vertical slot plate A3 for connecting the fixing strip A2, it is not only convenient to quickly fasten the first hook portion A21 on the fixing strip A2, but also to match battery modules E of different sizes, thereby adapting to the needs of different working hours.

[0023] The upper end of the bolt rod A4 has a threaded portion A41 that connects to the nut A5. The lower end of the bolt rod A4 is bent to form a second hook portion A42, and the frame A1 is provided with a mounting slot plate A6 for attaching the second hook portion A42. By using the second hook portion A42 at the lower end of the bolt rod A4 to quickly connect to the mounting slot plate A6 on the frame A1, and adjusting the tightness of the bolt rod A4 by rotating the nut A5, the fixing strip A2 can be quickly installed and removed.

[0024] The battery module E, control unit F, and drive assembly D are arranged sequentially from front to back on the frame A1. The front of the frame A1 is provided with a front compartment A11 for mounting the battery module E and control unit F, and the rear of the frame A1 is provided with a rear compartment A12 for mounting the drive assembly D.

[0025] The front end face of the front compartment A11 is provided with several grid holes A13. The front end of the frame A1 is provided with an insect-proof cover A14 covering the grid holes A13. An inner grid plate A15 is installed inside the front compartment A11, located between the vertical slot plates A3 and distributed alternately with the grid holes A13. The insect-proof cover A14 is funnel-shaped and has several small holes. By setting the insect-proof cover A14 and the inner grid plate A15 on both sides of the grid holes A13 of the front compartment A11, it is possible to effectively prevent mosquitoes from entering the front compartment A11 during field operations. At the same time, the multi-mesh design will not hinder the normal heat dissipation of the battery module E.

[0026] The partition A16 between the front compartment A11 and the rear compartment A12 is provided with a heat dissipation hole A17, and a fan for generating airflow is provided on the partition A16, which is located on one side of the heat dissipation hole A17.

[0027] In summary, this utility model uses a fixing strip A2 to install and fix the battery module E. By utilizing the quick-release connection structure between the fixing strip A2, the vertical groove plate A3, and the bolt rod A4, the battery module E can be quickly released, facilitating the replacement of the battery module E. This significantly increases the operating time of agricultural machinery, avoids the traditional screw fixing process of reverse locking, and prevents screw wear caused by frequent tightening and loosening, which could lead to the inability to fix the battery module E.

[0028] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
