Description

A detachable and portable labor-saving earth drill

technical field

The utility model relates to the field of soil tools, in particular to a portable labor-saving soil drill suitable for collecting samples of grassland agricultural soil and plant roots.

Background technique

Soil is the substrate for plant growth, and its physical and chemical properties play an important role in maintaining high productivity, long-lasting usability, good flat performance, and movement characteristics of artificially cultivated grassland. When monitoring the physical and chemical properties of soil, the soil drill is used as a soil Tools are a must.

At present, most of the economical and practical soil drills in actual production are "T"-shaped integrated handles. When collecting soil samples, they must be operated repeatedly by hand, which is not only laborious, but also easy to shake from side to side and destroy the soil profile; It is fixed, and it is not convenient for professionals of different heights to operate; in addition, the depth of soil sampling depends on the rough scale on the drill bit, which is not accurate, and the sampled soil is not easy to separate from the lower soil, which affects the accuracy of soil sample collection.

Contents of the invention

In view of the above situation, the purpose of this utility model is to provide a detachable portable labor-saving soil drill, which is easy to operate, labor-saving, and has high sampling accuracy, avoiding the inaccurate defects of traditional soil drill test results.

The technical scheme of the utility model is as follows:

A detachable and portable labor-saving soil drill includes a casing, a rotary handle, a bevel gear set, a drill rod, a drill bit, and a soil cutter. Inside, the rotary handle is installed on the outside of the shell, connected with the driving wheel through the transmission shaft, and the driven wheel is threaded with the drill pipe through the transmission gear shaft. The length of the drill pipe is scalable and hollow, and its side wall is provided with "n ”-shaped opening, the bottom end is movably connected to the drill bit, the drill bit is hollow and communicated with the drill rod, and a scale scale is set inside it, and a circular base with a diameter slightly smaller than the diameter of the drill bit is arranged under the scale scale, and the soil cutter is held by the handle , composed of a blade and a knife rod, the knife rod is placed in the groove set on the inner wall of the drill bit, the upper end of the knife rod passes through the drill bit to connect to the handle, and the lower end is welded to the blade. On the same plane, there are two soil cutters, which are symmetrically arranged at both ends of the drill bit.

Preferably, the handle of the soil cutting knife is a round handle, which is convenient for using force with one hand when drilling the soil.

Preferably, the blade has the same curvature as the side wall of the drill bit, and is placed in the groove provided on the side wall to reduce the resistance of the blade to the soil when drilling soil, saving time and effort.

Preferably, at least one cutting edge is provided at the bottom of the drill bit, which saves effort when drilling soil samples.

Preferably, the drill rod and the drill bit are made of stainless steel, which is sharp and wear-resistant, and will not pollute the collected soil samples.

Preferably, a handle is provided on the opposite side of the rotary handle, which is convenient for exerting force when drilling soil.

The detachable and portable labor-saving soil drill of the utility model aims at the use defects of the traditional soil drill, and the "T" handle is changed to a gear transmission rocker, which overcomes the inconvenience caused by turning the hand in the horizontal direction and saves labor; it is installed on the top of the drill bit. The scale scale is convenient for reading; the soil cutter is installed in the drill bit to improve the sampling accuracy.

When in use, the drill bit is fixed on the drill rod, and the soil drill is used for soil extraction. First, insert the soil drill vertically into the soil, hold the handle on one side of the shell with the left hand, and hold the rotating handle with the right hand, and turn it clockwise. Under the action of the drive shaft, the soil drill is transferred into the soil layer, observe the scale scale, and when the depth required for sampling is reached, the soil cutter installed on both sides of the drill bit is rotated to drill into the soil mass in the drill bit and the soil mass below. Separate, carefully unscrew the soil drill vertically, remove the drill bit from the drill pipe, and take out the soil sample with a soil cutter.

Detailed ways

As shown in Fig. 1 and Fig. 2, a detachable portable labor-saving earth drill includes a casing 1, a rotary handle 2, a bevel gear set 3, a drill rod 4, a drill bit 5, a soil cutter, and the bevel gear set 3 Comprising driving wheel 13 and driven wheel 14 engaged in transmission, which are installed inside the housing 1, the rotary handle 2 is installed on the outside of the housing 1, connected with the driving wheel 13 through a transmission shaft, and the driven wheel 14 is connected to the drill through a transmission gear shaft. The rod 4 is threaded, the opposite side of the rotary handle 2 is provided with a handle 12, the length of the drill rod 4 is scalable and hollow, its side wall is provided with an "n" shaped opening 6, and the bottom end is movably connected to the drill bit 5, the drill bit The bottom end of the 5 is provided with a cutting edge 15, the drill bit 5 is hollow and communicates with the drill rod 4, the drill rod and the drill bit are made of stainless steel, the inside of the drill bit 5 is equipped with a scale scale 7, and the scale scale 7 is provided below The diameter is slightly smaller than the circular base 8 of drill bit diameter, as shown in Figure 3, described soil cutting knife is made up of handle 9, blade 11 and knife bar 10, and described knife bar 10 is placed in the groove that drill bit inner wall is provided with, so The upper end of the cutter bar 10 passes through the drill bit to connect to the handle 9, and the lower end is welded to the blade 11. The blade 11 is in the shape of an upper arc sheet, and its blade is on the same plane as the bottom end of the drill bit. The soil cutter is provided with two symmetrical It is arranged at the two ends of the drill bit 5.

During specific use, first reset the scale scale 7, even if the circular base 8 of the scale scale 7 is at the lower end surface of the drill bit and is close to the upper end of the blade 11, fix the drill bit 5 and the drill pipe 4, and adjust the drill pipe according to the height of the operator 4, when starting the soil extraction operation, insert the drill bit 5 vertically into the soil, hold the handle 12 on one side of the casing tightly with the left hand, and hold the rotating handle 2 with the right hand, and turn it clockwise to drive the driving wheel 13 to rotate under the action of the transmission shaft , the drive wheel 13 drives the driven wheel 14 to rotate, and under the action of the transmission gear shaft, the soil drill is transferred into the soil layer, and the scale scale 7 advances upwards with the increase of soil samples, from the "n" shape of the drill pipe The scale scale 7 is observed through the opening 6, so as to obtain the penetration depth of the drill bit 5. When the depth required for sampling is reached, the soil cutter installed on both sides of the drill bit is rotated, and the soil body drilled into the drill bit 5 is separated from the lower soil body. The soil sample can be taken out with a soil knife.
