Description

Technical Field

[0001] The invention relates to the technical field of planting and digging, and in particular to a growth hole digging device for planting banana seedlings. Background Art

[0002] When planting banana seedlings, digging holes is a very important step, which directly affects the growth of the seedlings and the yield of the banana plantation. Proper digging holes not only provides a good growing environment for bananas, but also promotes the development of the root system and increases the survival rate of the seedlings.

[0003] When digging holes, the digging device cannot be placed straight down due to the uneven terrain. For example, on sloping ground, the digging device can only be placed tilted, and the dug hole can only be vertical to the sloping ground, but not vertically downward. Planting banana seedlings along the dug holes will eventually result in crooked banana seedlings, increasing the risk of the banana seedlings being blown down by the wind, especially in mountainous areas or coastal areas with strong wind speeds. In addition, the crooked banana seedlings may not be able to evenly expand their roots to the surroundings and downwards, limiting the banana seedlings' ability to absorb water and nutrients.

[0004] To this end, the present invention provides a growth hole digging device for planting banana seedlings. Summary of the Invention

[0008] As a further preferred solution, the friction ring is rotatably connected to the mounting frame, and the mounting frame is fixed with protruding rods symmetrically distributed along the mounting frame. The protruding rods are rotatably connected to adjacent friction rings, and first springs symmetrically distributed along the protruding rods are fixed between the protruding rods and the adjacent friction rings. The friction ring is fixed to the mounting frame through the protruding rods and the first springs.

[0009] As a further preferred solution, it also includes a fixed shell corresponding to the friction ring, the fixed shell is fixedly connected to the friction ring, a moving block is slidably connected in the fixed shell, the moving block is squeezed and fitted with the adjacent convex rod, the moving block has a movable groove, the mounting frame is slidably connected to a locking rod symmetrically distributed along the mounting frame, the locking block is slidably connected to the lifting block, the locking block is slidably connected to the adjacent locking rod, a threaded groove is opened in the locking rod, a rotating frame is threaded in the threaded groove, the rotating frame is rotatably connected to the mounting frame, the rotating frame is movably connected to the movable groove of the adjacent moving block, and a second spring symmetrically distributed along the locking rod is fixed between the locking rod and the mounting frame.

[0010] As a further preferred solution, a locking frame is also included, which is slidably connected to the frame. A pushing frame for pushing the locking frame downward into the soil is slidably connected to one side of the frame close to the extrusion frame, and the pushing frame is fixedly connected to the extrusion frame.

[0011] As a further preferred solution, the pushing frame contacts the locking frame, and the contact surface of the pushing frame is configured as an inclined surface.

[0012] As a further preferred solution, the device further includes telescopic rods symmetrically distributed along the locking frame, and the telescopic rods are fixed between the locking frame and the frame.

[0015] The present invention has the following advantages: the present invention utilizes the earth's centripetal force to enable the rotating frame to automatically and adaptively deflect left and right relative to the frame, and the mounting frame to automatically and adaptively deflect forward and backward relative to the rotating frame, so that the spiral frame can automatically adjust to a vertical downward position on the ground of any terrain, so that banana seedlings can be planted vertically, reducing the risk of the banana seedlings being blown down by the wind, while ensuring the ability of the banana seedlings to absorb water and nutrients.

[0016] The present invention fixes the rotating frame and the mounting frame respectively by frictionally cooperating the friction surface of the extrusion frame with the rotating frame, and by frictionally cooperating the extrusion frame with the friction ring, so as to prevent the rotating frame and the mounting frame from being deflected again due to the high-frequency vibration of the motor when digging the growth hole, thereby preventing the hole from being dug crooked.

[0017] When a hard stone is located directly below the spiral frame, the operator cannot continue to rotate the turntable frame, so the operator can quickly realize that a hard stone has been dug and stop digging downwards. When the hard stone is located slightly below the spiral frame, the locking block and the connecting block are disconnected in time, so that the turntable frame rotates idly and the spiral frame stops moving downwards to dig a hole. When the operator feels that the turntable frame rotates more easily, the operator can quickly realize that a hard stone has been dug and can also stop digging downwards in time to remove the hard stone.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to specific embodiments. It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] Example 1: A banana seedling planting growth hole digging device, such as Figure 1-Figure 3As shown, the machine comprises a frame 101, a handle 601 is fixedly connected to the upper rear side of the frame 101, the bottom of the frame 101 is rotatably connected to four rollers 102 symmetrically distributed along the left and right sides of the frame 101, the upper part of the frame 101 is rotatably connected to a rotating frame 104, the front side of the rotating frame 104 is rotatably connected to a mounting frame 105, the mounting frame 105 is rotatably connected to screws 106 symmetrically distributed along the left and right sides of the mounting frame 105, the screws 106 are threadedly connected to a lifting block 107, and the lifting block 107 is provided with a screw rod 106. A locking block 108 is provided, and a connecting block 109 is clamped on the locking block 108. A motor 103 is fixedly connected between the left and right connecting blocks 109. The output shaft of the motor 103 is fixedly connected to the spiral frame 1031 through a coupling. A fixing component is provided on the frame 101. After the frame 101 is placed stably, the rotating frame 104 and the mounting frame 105 are respectively fixed to the frame 101 and the rotating frame 104 through the fixing component. The mounting frame 105 is provided with a rotating component for driving the screw 106 to rotate.

[0034] like Figure 13 As shown, the rotating assembly includes a turntable frame 501, which is rotatably connected to the top of the mounting frame 105. A driving wheel 502 is fixed to the lower part of the turntable frame 501, and a driven wheel 503 is fixed to the top of the screw rod 106. The driven wheel 503 is engaged with the driving wheel 502.

[0035] The excavating device is pushed to the location where the hole is to be excavated in the banana seedling planting area. According to the specific terrain of the ground and the influence of gravity, the rotating frame 104 automatically and adaptively deflects left and right relative to the frame 101, and the mounting frame 105 also automatically and adaptively deflects forward and backward relative to the rotating frame 104, so that the spiral frame 1031 can automatically adjust to the vertical downward position on any terrain.

[0036] Then, the rotating frame 104 and the mounting frame 105 are fixed by the fixing assembly, and then the turntable frame 501 is rotated. The turntable frame 501 drives the driving wheel 502 to rotate, thereby driving the driven wheel 503 to rotate, and then drives the screw 106 to rotate, and then drives the lifting block 107 to move downward. The lifting block 107 drives the connecting block 109 to move downward through the locking block 108, and the connecting block 109 drives the motor 103 to move downward, so that the motor 103 drives the spiral frame 1031 to move downward. During the downward movement, the motor 103 is started. 3. The output shaft of the motor 103 drives the spiral frame 1031 to rotate, thereby digging a growth hole for the banana seedling downward. After digging is completed, the motor 103 is turned off, and the turntable frame 501 is rotated in the opposite direction, so that the driving wheel 502 drives the screw 106 to reverse through the driven wheel 503, thereby driving the lifting block 107 to move upward. The lifting block 107 drives the connecting block 109 to move upward through the locking block 108. The connecting block 109 drives the motor 103 to move upward, so that the motor 103 drives the spiral frame 1031 to move upward out of the hole.

[0037] Example 2: Based on Example 1, Figure 4-Figure 6 As shown, the fixing assembly includes an extrusion frame 201, which slides back and forth on the frame 101, and the rotating frame 104 passes through the extrusion frame 201. A friction surface is provided on the front side of the extrusion frame 201, and the extrusion frame 201 slides forward until the friction surface contacts and frictionally cooperates with the rotating frame 104 to fix the rotating frame 104. A threaded frame 202 is threadedly connected to the upper part of the frame 101, and the front end of the threaded frame 202 is rotatably connected to the extrusion frame 201. The rotating frame 104 is slidably connected in the front and rear directions with a limit block 203 symmetrically distributed along the left and right sides of the rotating frame 104, and the rear end of the limit block 203 is rotatably connected to the extrusion frame 201, and the mounting frame 105 is provided with a friction ring 204 symmetrically distributed along the left and right sides of the mounting frame 105. The limit block 203 moves forward to contact and frictionally cooperate with the adjacent friction ring 204 to fix the mounting frame 105.

[0038] In order to prevent the rotating frame 104 and the mounting frame 105 from being deflected again due to the high-frequency vibration of the motor 103 when digging the growth hole, thereby preventing the hole from being dug crookedly, the rotating frame 104 and the mounting frame 105 are fixed by the following specific operations: the threaded frame 202 is rotated to move the extrusion frame 201 forward until its friction surface contacts the rotating frame 104. At the same time, the extrusion frame 201 drives the limit block 203 to move forward until it contacts the friction ring 204. In this way, the rotating frame 104 is fixed by the friction cooperation between the friction surface of the extrusion frame 201 and the rotating frame 104, and the mounting frame 105 is fixed by the friction cooperation between the extrusion frame 201 and the friction ring 204.

[0039] like Figure 11 and Figure 12 As shown, it also includes a locking frame 401, which is slidably connected to the frame 101, and a telescopic rod 402 is fixed between the locking frame 401 and the frame 101, which is symmetrically distributed along the left and right sides of the locking frame 401. The upper side of the frame 101 is slidably connected to a pushing frame 403 along the front and back directions. The pushing frame 403 is fixed to the extrusion frame 201, and the pushing frame 403 contacts the top of the locking frame 401, and the contact surface of the pushing frame 403 is set to an inclined surface. When the pushing frame 403 slides forward, the locking frame 401 is squeezed downward into the soil through the inclined surface, and the telescopic rod 402 is compressed.

[0040] When the squeezing frame 201 moves forward, it drives the pushing frame 403 to move forward. The pushing frame 403 squeezes the locking frame 401 downward and inserts into the ground through the inclined surface, and the telescopic rod 402 is compressed. In this way, the frame 101 can be prevented from moving on the inclined ground due to the influence of the roller 102 without the need to hold the frame 101 by hand.

[0041] Example 3: Based on Example 2, Figure 7-10As shown, it also includes a fixed shell 301 corresponding to the friction ring 204, the fixed shell 301 is fixedly connected to the friction ring 204, the friction ring 204 is rotatably connected to the mounting frame 105, and the mounting frame 105 is fixedly provided with protruding rods 302 symmetrically distributed along the left and right sides of the mounting frame 105. The protruding rods 302 are rotatably connected to the adjacent friction rings 204. A first spring 303 symmetrically distributed along the front and back sides of the protruding rods 302 is fixedly connected between the protruding rods 302 and the adjacent friction rings 204. The friction ring 204 is fixed to the mounting frame 105 by the protruding rods 302 and the first springs 303. A moving block 304 is slidably connected to the fixed shell 301 in the up and down directions. The moving block 304 is connected to the adjacent protruding rods. 302 is extruded and fitted, and a movable groove is provided on the upper front side of the moving block 304. The mounting frame 105 is slidably connected to a locking rod 306 symmetrically distributed along the left and right directions of the mounting frame 105. The locking block 108 is slidably connected to the lifting block 107. The locking block 108 slides up and down in the adjacent locking rod 306. A threaded groove 307 is provided in the locking rod 306. The threaded groove 307 is threadedly connected to the rotating frame 305. The rotating frame 305 is rotatably connected to the mounting frame 105. The rotating frame 305 is movably connected to the movable groove of the adjacent moving block 304. A second spring 308 symmetrically distributed up and down along the locking rod 306 is fixed between the locking rod 306 and the mounting frame 105.

[0042] During the process of the spiral frame 1031 digging the hole downward, if a hard rock is located directly below the spiral frame 1031, the spiral frame 1031 will be blocked by the hard rock and cannot move downward any further, thereby preventing the turntable frame 501 from rotating any further. Therefore, it is necessary to stop digging the hole downward and remove the hard rock in time.

[0043] If the hard stone is located below the spiral frame 1031, the turntable frame 501 can still be rotated at this time, and due to the squeezing effect of the hard stone, the motor 103, the spiral frame 1031, the mounting frame 105, the protruding rod 302, the screw 106, the lifting block 107, the locking block 108 and the connecting block 109 are deflected forward or backward as a whole, and the first spring 303 is deformed to avoid the hard stone. However, in this case, the operator still continues to rotate the turntable frame 501, so that The spiral frame 1031 continues to dig a hole downward, and eventually the spiral frame 1031 will dig a crooked growth hole. To avoid this situation, it is necessary to disconnect the locking block 108 and the connecting block 109 in time, so that the turntable frame 501 rotates idly and the spiral frame 1031 stops moving downward to dig a hole. When the operator feels that the turntable frame 501 rotates more easily, he can quickly realize that he has dug a hard stone, and can also stop digging downward and remove the hard stone in time. Specifically, the locking block 108 and the connecting block 109 are disconnected by the following operation;

[0044] The mounting frame 105 and its upper components deflect forward or backward as a whole, causing the protruding rod 302 thereon to rotate relative to the friction ring 204. When the first spring 303 deforms adaptively, the protruding rod 302 squeezes the movable block 304 to slide downward along the fixed shell 301. The movable block 304 drives the rotating frame 305 to rotate through the movable groove. When the rotating frame 305 rotates, it cooperates with the threaded groove 307, causing the locking rod 306 to slide toward the side where the second spring 308 is compressed. The locking rod 306 pulls the locking block 108 to slide to disengage from the connecting block 109.

[0045] When the hard stone is removed, the mounting frame 105 returns to its vertical downward position, and the first spring 303 and the second spring 308 are reset. The second spring 308 drives the locking rod 306 to slide in the opposite direction and reset, thereby driving the locking block 108 to slide in the opposite direction until it re-engages the connecting block 109. The locking rod 306 drives the rotating frame 305 to reverse through the threaded groove 307, thereby driving the moving block 304 to slide upward and reset along the fixed shell 301.

The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
