Automatic fixed-point fertilization starting hammer

Abstract

The invention discloses an automatic fixed-point fertilization starting hammer which comprises an impact pneumatic hammer, a connecting rod, a drilling pin and a pneumatic conversion valve. The drilling pin is fixedly mounted below the connecting rod, a connecting sleeve is arranged at the bottom of the impact pneumatic hammer, the top of the connecting rod is movably mounted in the connecting sleeve, a hollow gas-pressure conveying pipeline is arranged inside the drilling pin, a discharge outlet is formed in the bottom of the drilling pin, a feed pipe is arranged on the connecting rod and is connected with the gas-pressure conveying pipeline and the pneumatic conversion valve, a high-pressure gas feed pipe, a fertilizer feed pipe and a comprehensive discharge pipe are arranged on the pneumatic conversion valve, and the comprehensive discharge pipe is connected onto the feed pipe of the connecting rod. The automatic fixed-point fertilization starting hammer has the advantages that drilling, soil loosening and fertilization operation can be carried out at fixed-point locations for urban trees under combined effects of the impact pneumatic hammer, the drilling pin and the pneumatic conversion valve, and the automatic fixed-point fertilization starting hammer is simple in structure, convenient to operate and high in fertilization efficiency and is small in occupied area during fertilization operation.

Description

technical field [0001] The invention relates to the field of maintenance equipment for urban greening and gardens, in particular to a starting hammer for automatic fixed-point fertilization. Background technique [0002] Urban greening has become one of the important components of today's urban construction. Due to the scarcity and tension of land resources in the city, the urban greening or trees occupy a small area, especially for the old trees on both sides of the road. It is difficult to maintain and fertilize these ancient trees. It is not possible to dig holes on the ground at the roots of the trees like traditional fertilization, and then put fertilizer into the holes to complete the fertilization work. [0003] Judging from the existing two main traditional fertilization methods, pit-digging fertilization is not suitable for urban roads. The main reason is that when digging pits, it is easy to cause damage to the roots of trees and affect the normal growth of trees;...

Due to the scarcity and tension of land resources in the city, the urban greening or trees occupy a small area, especially for the old trees on both sides of the road. It is difficult to maintain and fertilize these ancient trees. It is not possible to dig a hole at the root of the tree like traditional fertilization, and then put fertilizer into the hole to complete the fertilization work.

[0003] Judging from the existing two main traditional fertilization methods, pit-digging fertilization is not suitable for urban roads. The main reason is that when digging pits, it is easy to cause damage to the roots of trees and affect the normal growth of trees; secondly, digging Pit fertilization can only fertilize in one area of ​​​​the root of the tree, and cannot uniformly fertilize all positions of the root of the tree, which will also affect the normal growth of the tree; finally, this fertilization method is cumbersome to operate and has low work efficiency

Another traditional fertilization method is spraying fertilization on the ground, but these fertilization fertilizers cannot directly act on the roots of plants, which can easily cause fertilizer loss, and the practical effect is also very poor
