Description

Handheld earth drill

Technical Field

The utility model relates to the technical field of soil drills, in particular to a handheld soil drill.

Background Art

Soil sampling is an important part of modern agriculture and environmental ecology. The basic properties of soil can be understood by taking soil samples, and the soil drill is a necessary sampling tool for obtaining soil samples.

Soil augers can be divided into two categories: manually operated and mechanically operated. Among them, there are more types of manually operated soil augers. When collecting soil samples for chemical analysis or physical analysis that does not require original soil, open-type soil augers are used; when collecting original soil that does not need to destroy the soil structure or properties, sleeve-type soil augers are used.

However, when using a handheld open-type soil auger or a sleeve-type soil auger, the user needs to press the handle on the top of the soil auger by hand to press the soil auger to a certain depth. After taking out the soil auger from a certain depth, the user can only push the soil in the soil extraction tube out by pressing the handle with the hand. In this process, due to the large friction between the soil extraction tube and the soil and the inconvenience of pushing the soil, the user needs to exert a lot of effort to push the soil out. Although mechanical drills are more efficient in extracting soil and save manpower, they are not as light and flexible as handheld soil auger. At the same time, mechanical drills are heavy and inconvenient for users to carry during work. Therefore, when soil samples need to be tested, handheld soil auger is still preferred.

It can be seen that how to provide a labor-saving and lightweight handheld earth drill is a problem that needs to be solved urgently.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model aims to provide a handheld soil drill to solve the problems existing in the prior art, so that the user can take soil and push soil by leg strength, which is labor-saving, light and easy to operate.

In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

As shown in Figures 1 to 3, this embodiment provides a handheld soil drill, including a soil frame, a bulldozer rod 1 and a bracket 2. A soil barrel 3 is provided at the bottom of the soil frame, and the soil barrel 3 is used to be inserted into the soil for soil extraction. A handle 4 is provided at the top of the bulldozer rod 1, and a bulldozer block 5 is provided at the bottom of the bulldozer rod 1. A foot frame 6 is provided on the bulldozer rod 1, and the bulldozer rod 1 is slidably connected to the soil frame so that the bulldozer block 5 can push the soil in the soil barrel 3 out; the bracket 2 is used to support the soil frame so that the soil barrel 3 can be pushed out. The bottom is suspended in the air; when taking soil, the soil frame is pressed to insert the soil barrel 3 into the soil for taking soil. When encountering hard soil, the soil frame can be stepped on to assist the upper limbs to apply force together; when pushing soil, the soil frame is first placed on the bracket 2 so that the bottom of the soil barrel 3 is suspended in the air, and the soil in the soil barrel 3 can pass out from the bottom of the soil barrel 3, then, the handle 4 on the top of the push rod 1 is pressed, and at the same time, the foot frame 6 on the push rod 1 is stepped on to push the soil in the soil barrel 3 through the push block 5 at the bottom of the push rod 1. The handheld soil drill provided in this embodiment is convenient for users to take soil and push soil by leg strength, which is labor-saving, light and easy to operate.

In this embodiment, the soil-taking frame includes a cross bar 7, two vertical bars 8 and a foot plate 9. The bottom of the cross bar 7 is connected to the top of the foot plate 9 through two vertical bars 8. The foot plate 9 is provided with a through hole. The soil-taking barrel 3 is arranged at the bottom of the foot plate 9 and is connected with the through hole. When taking soil, the cross bar 7 is pressed hard to transmit the force to the soil-taking barrel 3 through the two vertical bars 8, so that the soil-taking barrel 3 is inserted into the soil for taking soil. When encountering harder soil, the upper limbs can be assisted by stepping on any side of the foot plate 9. The same force is applied; in this embodiment, the two sides of the foot frame 6 of the bulldozer rod 1 are respectively slidably connected to the two vertical rods 8, so that the bulldozer block 5 can slide up and down in the soil-taking barrel 3. When taking soil, the soil enters the soil-taking barrel 3 and pushes the bulldozer block 5 upward to a position close to the foot plate 9. When bulldozing, the soil-taking frame is placed vertically on the bracket 2, and the handle 4 at the top of the bulldozer rod 1 is pressed down. At the same time, the foot frame 6 on the bulldozer rod 1 is stepped on to push the bulldozer block 5 downward into the soil-taking barrel 3, thereby pushing out the soil in the soil-taking barrel 3.

It should be noted that the foot frame 6 in this embodiment has a certain width, which can reduce the pressure on the contact surface between the user's foot and the foot frame 6 after exerting force, thereby increasing comfort. Similarly, the foot plate 9 also has a certain width.

In this embodiment, a slope-shaped cutout is provided at the bottom of the soil-extracting tube 3 to facilitate the insertion of the soil-extracting tube 3 into the soil.

Furthermore, when the soil-boring barrel 3 is arranged vertically, the angle between the inclined surface of the slope-shaped cutout and the horizontal plane is 60°.

In this embodiment, the bracket 2 is a cylindrical bracket, and a groove is provided on each side of the top of the cylindrical bracket, and the width of the groove matches the width of the foot plate 9; specifically, the cylindrical bracket in this embodiment is composed of a plurality of straight rods connected between two upper and lower circular rings, wherein the two sides of the upper circular ring are each concave to form a groove, so that the two sides of the foot plate 9 of the soil borrowing frame can be placed in the two grooves respectively, thereby increasing the stability of the soil borrowing frame placed on the cylindrical bracket.

In this embodiment, the height of the cylindrical support is at least twice the length of the soil taking tube 3, which satisfies the requirement of ensuring the integrity of the taken soil regardless of whether the original soil needs to be taken or not.

In summary, compared with the handheld soil drills currently produced on the market, the handheld soil drill provided in this embodiment realizes the use of legs and feet in the process of taking soil and pushing soil, increases the degree of labor saving in the process of pressing the soil taking tube 3 into the soil and taking out the soil in the soil taking tube 3, so that the user can save more physical strength when collecting a large number of samples. The main body of the traditional soil drill is a cylindrical tube, and the interior is a connecting rod connected to a bulldozer block. Compared with this device, it is heavier as a whole. The reason is that the realization of the soil taking and pushing functions of the traditional soil drill requires the handle at the top of the cylindrical tube and the handle at the top of the connecting rod. The middle main body of the soil drill needs to bear the force transmission, so the structure of the soil drill is required to be more solid and heavier; while the present device is convenient for users to take soil and push soil by leg strength, and the force application distance is shorter, so that the force borne by the middle main body of the present device is smaller. Therefore, the overall structure of the present device is lighter and can meet the use requirements without heavy structural design.

The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
