Soil perforating device

Abstract

The invention relates to the field of soil perforating equipment, in particular to a soil perforating device. The soil perforating device comprises a device body, a power unit, an upper mould base, a lower mould base, guide rods, a mould sleeve, a drill bit and a cleaning unit. The power unit is mounted on the device body. The upper mould base is located under the power unit and fixedly connected with the device body. A pressure plate is mounted at the top of the upper mould base. The lower mould base is located below the upper mould base and connected with the upper mould base through the guide rods. The mould sleeve is mounted on the upper mould base and the lower mould base. The drill bit penetrates through the mould sleeve to be connected with the power unit. The shape of the cross section of the drill bit is a spherical triangle. The cleaning unit is mounted under the lower mould base and used for clearing away soil on the drill bit, thereby avoiding intensifying of abrasion between the drill bit and the mould sleeve. The soil perforating device provided by the invention is mainly used for drilling square holes in farm soil, gaps between the square holes and square cement columns are small, soil does not need to be added into the gaps, and the number of steps for mounting the square cement columns is decreased.

Description

technical field [0001] The invention relates to the field of soil drilling equipment, in particular to a soil drilling device. Background technique [0002] When using greenhouses to grow off-season vegetables or fruits, growers will erect greenhouse skeletons. Since square cement columns have stronger bearing capacity and greater pull-out resistance than cylindrical columns, growers generally use square cement columns as the skeleton. [0003] However, before the square cement column is fixed, a square hole needs to be drilled in the soil to embed the square cement column in the soil. In order to dig out suitable square holes in the soil, some growers often use the method of manual digging. Although this method can dig out more suitable square holes, it is time-consuming, laborious and inefficient, and is not suitable for a large number of square holes. Excavation; Some planters will use the device for drilling round holes in the prior art to drill holes. Although this met...

In order to dig out suitable square holes in the soil, some growers often use the method of manual digging. Although this method can dig out more suitable square holes, it is time-consuming, laborious and inefficient, and is not suitable for a large number of square holes. Excavation; some planters will use the device for drilling round holes in the prior art to drill holes. Although this method is labor-saving, the round holes drilled do not match the square cement columns, making the square cement columns unreliable after being embedded in the soil; And in the prior art, some equipment that can punch square holes have also appeared. For example, the application number is: a Chinese patent of 201310301768.8 discloses a kind of soil punching machine, which can punch square holes matched with square cement columns. It can solve the problem of drilling square holes to a certain extent. However, the technical solution uses vibration to realize drilling. Vibration can easily make the square hole larger, resulting in the size of the square hole being turned out each time. The drilling accuracy of the scheme is not high, and there will still be a large gap between the square cement column and the square hole, so that the square cement column cannot be firmly fastened in the soil, and it is necessary to manually fill the gap with soil, which is troublesome to operate
