Small ditching, fertilizing and earthing all-in-one machine for hills and mountains

Abstract

The invention discloses a small ditching, fertilizing and soil covering all-in-one machine for hills and mountains. The all-in-one machine comprises a rack, a walking frame, an engine, a ditching cutter, a soil covering cover, a fertilizing device, a transmission device, a traveling device and a tilling depth adjusting device. The all-in-one machine is simple in structure, ditching, fertilizing and soil covering integrated operation can be completed, the working efficiency is effectively improved, and the tilling depth can be adjusted and stabilized through the tilling depth adjusting device; a traveling system is designed, and two iron segmented grid type land pressing wheels are adopted as traveling wheels, so that the trafficability of the machine in hills and mountains is improved; and the fertilizer applying system is provided with a fertilizer feeding clutch device, so that a switch of the fertilizer feeding system can be controlled according to actual requirements, and the fertilizer is effectively saved.

Description

technical field [0001] The invention relates to a reclamation machine for hilly and mountainous areas, in particular to a small integrated machine for ditching, fertilizing and covering soil in hilly and mountainous areas. Background technique [0002] In the process of planting fruit trees, fertilization is an important factor affecting fruit yield and quality. However, the mechanization level of orchard management in my country is still relatively backward, and most of the fertilization of fruit trees is manual work. Artificial fertilization is not only time-consuming and laborious, but also the depth of the fertilization ditch is inconsistent, the amount of fertilization is uneven, and it is difficult to meet the technical requirements of fertilization. [0003] The existing orchard fertilization machinery has a single function, and cannot complete ditching, fertilization, and soil covering operations at one time, and the work efficiency is low. Moreover, small trencher...

AI Technical Summary

Problems solved by technology

Although the crawler chassis has a certain ability to climb and overcome obstacles, the crawler chassis itself requires a large operating space and is not suitable for dense hilly orchards.

[0011] Document 8: A small vertical orchard ditching, fertilizing, and soil-covering integrated machine, application number: 201611060865.2. Although this patent can complete the integrated operation of ditching, fertilization, and soil-covering at one time, the patent is articulated by three-point suspension At the rear of the tractor, the working environment required for work is relatively large, which is not suitable for fertilization operations in orchards in hilly and mountainous areas. Moreover, the patented ditching device adopts the form of a vertical rotary tiller. When ditching, only the ditch is not excavated, which is easy to cause drainage. The fertilizer port blocks the soil, and the fertilizer discharge port is below the surface, so it is impossible to find out whether the fertilizer is discharged in time, which is a major defect of the invention

In addition, when the machine is moving forward, the fertilizer discharge pipe must squeeze the soil to move forward. Although the soil has been crushed, it still produces a lot of resistance. Cutting the soil repeatedly, wasting resources

[0012] In summary: the ditching and fertilizing machines described in the above documents have their respective advantages, but each also has the following problems: ①, the integrated operation of ditching, fertilizing and soil covering cannot be completed at one time (such as document 1); ②, the complete machine The structural arrangement is not very reasonable, and some of the sizes are large or long, which affects the stability and operational flexibility of the whole machine (such as document 2 / 3 / 4) ③. The structural design of some devices is unreasonable, which affects the completion of some functions (such as Document 3 / 4 / 5) ④. Some machines need to be hooked behind the tractor, or use crawler chassis vehicles as power, which requires a large working space and is not suitable for fertilization operations in hilly and mountainous orchards

⑤. Part of the machine design causes the machine to generate too much unnecessary work resistance, resulting in a waste of resources and energy (such as document 3 / 4 / 8)
