Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and in particular relates to a body balancing device for a seed drill. Background Art

[0002] The level of agricultural mechanization in my country is highly uneven across different industries and regions. This is particularly true in hilly and mountainous areas, where the comprehensive mechanization rate for crop cultivation and harvesting is only 53.5%, approximately 20 percentage points lower than the national average.

[0003] The hilly and mountainous terrain in existing technology presents a high demand for agricultural machinery. Operating in such environments, seed drills require excellent maneuverability, safe operation on slopes, and maneuverability in confined spaces. This significantly increases the difficulty and manufacturing cost of developing seed drills suitable for hilly and mountainous areas. This is especially true when faced with uneven soil surfaces. Due to the length of the seed drill, it may not be able to fully adapt to the height difference between the left and right sides, hindering its full seeding performance. This leads to a decrease in seed drill operating quality. Missed seeds, repeated seeds, insufficient seeding depth, and uneven seeding depths can significantly impact yields, reducing farmers' profits. Utility Model Content

[0022] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and to facilitate its implementation.

[0023] like Figures 1 to 2 As shown, the utility model is a balancing device for a seeder body, which increases the pressure on the side of the seeder where the pressure on the ground is smaller in hilly and mountainous areas by assembling a counterweight module to slide left and right, thereby ensuring the stability and balance of the body and thus ensuring the sowing effect.

[0024] Specifically, if Figures 1 to 2As shown, it includes two welded hanging plates 1 and two slide rails 2. The two slide rails 2 are fixedly connected between the tops of the two welded hanging plates 1. Both sides of the tops of the two slide rails 2 are fixedly connected to bearing seats 3. An intermediate transmission shaft 4 runs through the opposite sides of the two bearing seats 3.

[0025] Motor 5, the output shaft of motor 5 is fixedly connected to one end of transmission shaft 4;

[0026] Two toothed sprockets 6, the two toothed sprockets 6 are respectively fixedly connected to the surfaces of the two transmission shafts 4;

[0027] Chain 7, chain 7 is connected between two toothed sprockets 6;

[0028] The slider base 8 is slidably connected to the top of the two slide rails 2;

[0029] The counterweight support 9 is fixedly connected to the top of the slider base 8;

[0030] The counterweight assembly 10 is fixedly connected to the top of the counterweight support 9;

[0031] A control switch 11 is electrically connected to the motor 5;

[0032] The top of the chain 7 is fixedly connected to the bottom of the counterweight support 9.

[0033] The counterweight assembly 10 includes a plurality of counterweight blocks 101 . The counterweight blocks 101 are disposed on top of the counterweight support 9 , and the counterweight blocks 101 are fixedly connected by bolts 102 .

[0034] The specific working method is described below with specific embodiments: Example 1

[0035] The staff installs the entire device until it is in the corresponding position of the seed drill. During the seeding process, the motor 5 is controlled to rotate forward and reverse, thereby driving the transmission shaft 4 and the sprocket 6 to rotate, so that the chain 7 drives the counterweight assembly 10 to slide along the slide rail 2 through the slider base 8;

[0036] After calculation based on the data information such as the driving counterweight block's moving speed of approximately 15m / min, weight, slide rail friction coefficient, working safety factor, and chain drive efficiency, a 200w, 12v DC reduction motor is used to drive it while ensuring sufficient safety. The speed is selected between 180 and 200 rpm and is controlled by the forward and reverse switch. The counterweight block can be retained at any position in the left and right directions of the seeder to ensure the balance of the seeder during operation.

[0037] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above-mentioned concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
