Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of farmland fertilizer spreading vehicles, in particular to a farmland fertilizer spreading vehicle with adjustable wheelbase. Background Art
[0002] With the advancement of science and technology, traditional agricultural methods can no longer meet the growing social needs. In modern agricultural production, a large number of mechanical equipment have been applied to all aspects of the process. For example, in terms of fertilization, farmland fertilizer vehicles have replaced traditional manual fertilization operations, and its efficiency has been greatly improved. The density of fertilization will not cause the problem of too much or too little manual fertilization. However, in actual farmland operations, farmland fertilizer vehicles mostly walk in preset grooves in the farmland, and the layout of different farmlands is different, and the distribution of their grooves is different. This makes it possible for the same farmland fertilizer vehicle to be unable to walk in the preset grooves in different farmlands, resulting in difficulty in the movement of the farmland fertilizer vehicle. Due to the different moisture levels of the farmland soil, the farmland fertilizer vehicle may also fall into an area with high humidity, thereby affecting normal fertilization operations.
[0003] Secondly, except for the ridges and preset trenches in the farmland, most other areas are planted with crops. Due to the fixed wheelbase, the farmland fertilizer applicator may not be able to travel in the trenches, causing its wheels to run over the crops, affecting their normal growth and even causing the death of the crops in severe cases.
[0004] In summary, there are some problems in the use of the farmland fertilizer spreading vehicle whose wheelbase cannot be adjusted, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
