By doing so, the ground surface layer is finely crushed and the chemical solution is supplied to the crushed soil.
Description
The present invention relates to a soil crusher, and more particularly, to a soil crusher capable of simultaneously performing soil refinement and / or liquid fertilizer (liquid fertilizer) in addition to crushed soil.
The cultivated land is generally aged by the frequent running of the agricultural machinery, so that the soil is hardened and the hardened hard layer is formed between 20 ~ 40cm depth. The increase in the use of large agricultural machinery and the feed of livestock straw are increasing the severity of cirrus stratification. The weathering layer is very poor in air permeability and drainage due to the very small amount of soil porosity. If soil water drainage deteriorates, crops can cause droughts and greatly reduce the vitality of roots, resulting in low productivity.
Subsoil fracture is known to be a good way to solve this problem. According to a survey by the Agricultural Promotion Agency, it is known that about 440,000 hectares, which is about half of the rice fields in Korea, need to be shattered. In order to cultivate the crops such as soybeans in these paddy fields, it is necessary to disrupt the deep-sea soil to a depth of about 35 cm prior to cultivation in a cycle of 3 years (nitrogen oxide) and 5 years (sandy soil) To about 40%.
In this way, it is recognized that the subsoil crushing operation that crushes the excavation layer is an indispensable work in agriculture. As one of them, there is a " deep-sea shredder " proposed by Kwon Tae-wun in Korean Patent Publication No. 10-2012-0119287 (published on October 31, 2012). 1 comprises a
Other prior art techniques for soil disruption include the following soil shredding apparatus: Korean Patent Registration No. 10-1161535 (Registered on June 25, 2012, Green Solution Co., Ltd., 2 persons, name of invention: Pollution Korean Patent Laid-Open Publication No. 10-2009-0104464 (published Oct. 06, 2009, Cornell D. Flebeni et al., Entitled Compression Fracture and Multicomponent Liquid or Solid Media (Method and Apparatus for Improving Efficiency of Soil and Groundwater Pollution by Underground Pollution).
All of these conventional deep-sea crusher apparatuses have a common point that soil is crushed using compressed air. However, there is a limitation that the crusher devices have only soil crushing function. The crusher devices do not have the ability to perform other operations besides soil crushing, such as fertilizing the soil or applying the soil improvement agent to improve the soil. Therefore, cultivators using the subsoil crusher, apart from the subsoil crushing operation using it, have to work separately with separate equipment to administer the liquid fertilizer and / or soil amendment agent to the soil. Soil modifier is an organic synthetic polymer used in soil for the purpose of improving the physical properties by soil or grafting various materials used in soil to improve physically, chemically and biologically unhealthy soil. Soil modifiers are available in liquid and solid (powder) form.
In addition, the conventional manual moving type crusher, in which a worker pulls or pushes, is a structure in which the crushing rod penetrates into the ground due to a pressing force of the operator. To put the crushing rod deep into the ground, the operator must use a lot of force. In addition, there is a limit to the depth of penetration of the crushing rod into the ground by the force of the operator alone.
In view of the limitations of the prior art, it has been found that by supplying the compressed air with the liquid fertilizer and / or the soil improving agent in the infiltration crushing rod that digs into the ground, the supply of fertilizer and / or soil conditioner to the crushed soil, And to provide a deep-sea crusher capable of being constructed.
Another object of the present invention is to provide a groundwater crusher designed to allow an operator to dig into the ground while rotating by a mechanical power to perform crushing layer crushing work without difficulty.
According to an aspect of the present invention to achieve the above object, there is provided an electronic device including: a housing; Vertical lifting means 160 supported by the
In the bottom soaking machine, the housing includes an
The penetrating crushing rod includes an
Wherein at least four openings are provided at corresponding points of the inner tube and the outer tube, wherein the compressed air and the chemical liquid are injected into the soil in the radial direction of the north, south, south, and south of the penetrating crush rod through the at least four openings .
The inner pipe is coupled to the compressed air tank so as to receive the vertical lift force directly from the compressed air tank. An electronically controlled valve for opening and closing the pipe is controlled by the control means on the upper pipe of the inner pipe It is desirable to install more.
The external appearance rotating means includes an electrically driven motor; A first gear coupled to an axis of the motor; A second gear coupled to the upper end of the outer tube so as to be integrally rotatable with the outer tube and engaged with the first gear to rotate the outer tube by the rotational force of the electric motor; And connecting the motor to at least one of the vertical raising and lowering means, the engaging member, the compressed air tank, and the chemical solution tank so that the motor can receive the vertical raising and lowering force directly or indirectly, And a motor support member for supporting the motor support member. In addition, the control means controls the motor to generate a rotational force while the vertical up-down means generates vertical down-force.
In this case, the bottom shovel crusher is disposed below the second gear and is coupled to at least one of the vertical ascending / descending means, the compressed air tank, the chemical solution tank, and the coupling member, A gear supporting member coupled to the housing to allow the sliding movement in the vertical direction along the housing; And a ring-shaped bearing fixed to the gear receiving member while rotatably supporting the second gear directly below the ring-shaped bearing.
Preferably, the inner tube and the chemical liquid tube are communicated with each other through a chemical liquid tube, and the chemical liquid tube is provided with an electronically controlled valve for opening and closing the tube, the opening and closing of which is controlled by the control means.
According to an example, the vertical up-and-down
Wherein the shovel crusher comprises: a hydraulic pipe constituting a closed hydraulic circuit between an external hydraulic pressure supply device and the hydraulic cylinder; And an electrically controlled valve disposed in the hydraulic line for opening and closing the hydraulic line. In this case, it is preferable that the control unit controls the hydraulic pressure supply unit to operate and controls the electrically-controlled valve to be in the open state while the hydraulic pressure supply unit is in operation.
The hydraulic pressure supply device is preferably a bi-directional hydraulic pump.
According to the groundwater crusher of the present invention, the following effects can be obtained.
The present invention enables simultaneous discharge of compressed air and injection of liquid fertilizer and / or soil conditioner using compressed air produced by using one air compressor. It enables the crushing of the subsoil and the subsoil application of the liquid fertilizer and / or the soil improvement agent to be carried out at once, thus greatly enhancing the efficiency of the associated work. It also maximizes the input of fertilizer and soil amendment into the soil. Furthermore, it can reduce the cost of purchasing equipment for farmers because it allows two or three operations to be performed simultaneously by a single air compressor.
The ground shredding apparatus of the present invention uses a rotating force of a drill of a penetrating and crushing rod portion driven by a motor and a hydraulic or pneumatic cylinder pressing force together. Since the penetrating crushing rod is rotated and pressed, the penetrating crushing rod can be penetrated deeper than the conventional crushing machine. In addition, since the penetration force is generated by using a motor and a hydraulic or pneumatic cylinder, the operator does not need to apply a large force. The penetrable depth can be adjusted to the desired level. It can penetrate to a depth of 40 cm or more, preferably to a depth of 70 to 80 cm, and can be crushed. This ability to penetrate deep clay can also be used to practice crossing where it is not possible to have a crossbow (work to feed a pipe under a tree).
In addition, this deep-sea crusher can be manufactured in a small size and has good mobility using wheels. Soil-shredding can be carried out even in the presence of crops on the cultivated land so that the effect can be obtained. The furrows of farmland are likely to become hard due to frequent passage of people and farm machinery. The ground shredding apparatus of the present invention can perform the shredding operation along the trough. Such work can be a great help to the root growth of the crops planted in the ditch.
