TECHNICAL FIELD

[0001] The utility model relates to a hole digging tool technical field, and specifically relates to a rotary soil hole digging operation tool. BACKGROUND

[0002] The existing hole digging tool usually adopts traditional tools such as Luoyang spade, and these tools are usually in the form of semi-cylindrical structure, which is hammered into the soil layer by artificial to dig holes. However, this traditional hole digging method has obvious shortcomings. First, the tool needs to be hammered into the soil layer repeatedly by artificial during hole digging, which not only consumes time and effort, but also is inefficient, especially in hard soil or deeper soil layer, the operation process is more complicated, and the labor intensity is large. In addition, the traditional hole digging tool lacks effective soil storage function when breaking soil. Although the tool can cut or break the soil layer to a certain extent, the broken soil often lacks good fixing and storage mechanism, which causes the broken soil to easily fall or be disturbed by the outside environment and cannot be smoothly taken out.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 1-8 A rotary soil hole digging tool, comprising a hole digging assembly A, a hole digging assembly B, a connecting sleeve 2, a driving rod 3, a driving sleeve 4, the hole digging assembly A comprising a connecting bracket 111, a mounting sleeve 112, and soil breaking teeth 113 fixedly connected to the bottom of the mounting sleeve 112 and uniformly distributed in an annular array, the connecting bracket 111 being fixedly connected to the mounting sleeve 112; the hole digging assembly B comprising a connecting rod 121, a main soil breaking cutter 122, and an auxiliary soil breaking cutter 123, the connecting rod 121 being fixedly connected with two groups of main soil breaking cutters 122 distributed in an annular array, the main soil breaking cutters 122 being arranged obliquely, the auxiliary soil breaking cutter 123 being fixedly installed on the main soil breaking cutter 122 in a detachable manner, and the connecting bracket 111 and the connecting rod 121 each being fixedly connected with an assembly rod 13.

[0032] The driving rod 3 is fixedly installed at the top end of the assembly rod 13 through the connecting sleeve 2, the driving rod 3 is fixedly connected with a transmission sleeve A 31 on the periphery, the transmission sleeve A 31 is provided at the top end with evenly arranged ratchets A 32, the driving sleeve 4 is plugged into the periphery of the driving rod 3, and the driving sleeve 4 is fixedly connected with a transmission sleeve B 41 inside, and the transmission sleeve B 41 is provided at the bottom end with evenly arranged ratchets B 42 which are in matching engagement with the ratchets A 32.

[0033] The driving rod 3 can be fixedly combined with the assembly rod 13 matched with the hole digging assembly A or the hole digging assembly B through the connecting sleeve 2, and the bottom end of the hole digging assembly A or the hole digging assembly B is inserted into the ground, and the driving sleeve 4 is operated to rotate, so that the driving rod 3 and the assembly rod 13 are synchronously rotated, and then the hole digging assembly A or the hole digging assembly B is used to dig a hole downward.

[0034] When the driving sleeve 4 and the transmission sleeve B41 rotate towards the straight side of the ratchet B42, the straight side of the ratchet B42 is in abutting connection with the ratchet A32, so that the driving rod 3 and the assembly rod 13 are driven to rotate, thereby realizing the operation of digging a hole downward. When the driving sleeve 4 rotates by a certain angle and it is inconvenient to continue to rotate due to the body posture, the driving sleeve 4 can be reversely rotated, at this time, the inclined side of the ratchet A32 is matched with the inclined side of the ratchet B42, so that the driving sleeve 4 and the transmission sleeve B41 jump upward under the action of the ratchet B42, thereby realizing the reset of the driving sleeve 4, and then the driving sleeve 4 can be continuously rotated in the forward direction to drive the hole digging assembly A or the hole digging assembly B to dig a hole.

[0035] For the hole digging assembly A, the soil breaking teeth 113 thereon are designed as a structure similar to a ratchet, which can effectively break the soil during rotation, and the broken soil is stored in the mounting sleeve 112. After digging to a certain depth, the hole digging assembly A can be taken out and the soil in the mounting sleeve 112 can be removed, and the hole digging operation can be continued. The hole digging assembly with such a structure can efficiently break the soil layer and effectively store the broken soil, which facilitates the removal of the soil.

[0036] For the hole digging assembly B, the two groups of main soil breaking cutter heads 122 arranged in an inclined manner can cut the surrounding soil layer during operation, and the broken soil can be transferred above the main soil breaking cutter heads 122 during continuous rotation, thereby facilitating the removal of the broken soil.

[0037] The main soil breaking cutter head 122 and the auxiliary soil breaking cutter head 123 are both in a semicircular structure, and the size of the auxiliary soil breaking cutter head 123 is greater than that of the main soil breaking cutter head 122. When a hole with a large diameter needs to be dug, the auxiliary soil breaking cutter head 123 with a larger size is assembled on the main soil breaking cutter head 122, which can widen the inner diameter during hole digging.

[0038] To ensure that the auxiliary soil breaking cutter head 123 can be fixedly installed on the main soil breaking cutter head 122 in a detachable manner, the following technical solutions are provided.

[0039] The main soil breaking cutter head 122 and the auxiliary soil breaking cutter head 123 are both in a semicircular structure, and the size of the auxiliary soil breaking cutter head 123 is greater than that of the main soil breaking cutter head 122. When a hole with a large diameter needs to be dug, the auxiliary soil breaking cutter head 123 with a larger size is assembled on the main soil breaking cutter head 122, which can widen the inner diameter during hole digging.

[0040] The main and auxiliary soil breaking cutters 122 and 123 are assembled and disassembled by the bolt assembly 125, so that holes with different diameters can be conveniently punched.

[0041] To facilitate the effective rotation of the driving sleeve 4 on the driving rod 3, the following technical solution is provided.

[0042] The main handle 51 and the auxiliary handle 52 are coaxially arranged on the outer wall of the driving sleeve 4, and the auxiliary handle 52 is detachably inserted and fixed on the insertion rod 43.

[0043] The main handle 51 and the auxiliary handle 52 are coaxially arranged on the outer wall of the driving sleeve 4, and the auxiliary handle 52 is detachably inserted and fixed on the insertion rod 43.

[0044] When there are obstacles around the hole punching position, the obstacles will block the effective operation of the main handle 51 or the auxiliary handle 52 when the auxiliary handle 52 is assembled on the insertion rod 43 to rotate the driving sleeve 4. To solve this problem, the following technical solution is provided.

[0045] The outer diameter of the driving rod 3 is not greater than the outer diameter of the insertion rod 43, and the auxiliary handle 52 is detachably fixed to the top end of the driving rod 3.

[0046] When punching a hole near an obstacle, the auxiliary handle 52 can be fixed to the top end of the driving rod 3 and arranged in the vertical direction. Due to the lack of interference of the auxiliary handle 52, the rotary soil hole punching tool can rotate in a large angle range without being disturbed by the obstacle.

[0047] To facilitate the detachable and quick insertion and assembly of the connecting sleeve 2, the assembly rod 13, the driving rod 3, the auxiliary handle 52 and the insertion rod 43, the following technical solution is provided.

[0048] The connecting assembly 6 further comprises an assembly pin rod 61 and a clamp 62, one end of the clamp 62 is rotatably installed on the assembly pin rod 61, and the other end of the clamp 62 is sleeved on the outer periphery of the assembly pin rod 61.

[0049] The assembly pin rod 61 is inserted into the assembly rod 13, the driving rod 3, the connecting sleeve 2, the insertion rod 43 and the auxiliary handle 52.

[0050] Pin holes are formed in the corresponding parts of the assembly rod 13, the driving rod 3, the connecting sleeve 2, the insertion rod 43 and the auxiliary handle 52 to ensure that the assembly pin rod 61 is effectively inserted therein.

[0051] When the connecting sleeve 2 is combined with the driving rod 3 and the assembling rod 13, the assembling pin rod 61 is inserted into the pin holes at the upper and lower ends of the connecting sleeve 2, and is fixedly connected with the internal assembling rod 13 and the driving rod 3 respectively, so as to realize the quick connection of the driving rod 3 and the assembling rod 13.

[0052] When the auxiliary handle 52 is assembled on the inserting rod 43 or the driving rod 3, the assembling pin rod 61 can also be arranged through the auxiliary handle 52 and the inserting rod 43 or the driving rod 3, so as to realize the quick assembly of the auxiliary handle 52.

[0053] It should be noted that when the rotary soil hole digging tool is lifted upward by the main handle 51 and the auxiliary handle 52 to take out the broken soil, in order to avoid the driving sleeve 4 from being separated from the top end of the driving rod 3, a set of the connecting assembly 6 can be assembled at the top of the driving rod 3 in advance, which can limit the driving sleeve 4 from being separated.

[0054] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims should be included in the present application.
