Description

Technical Field

[0001] The invention belongs to the technical field of hole drilling for ganoderma lucidum cultivation, and in particular relates to a hole drilling device for ganoderma lucidum cultivation. Background Art

[0002] As a precious medicinal fungus, outdoor cultivation of Ganoderma lucidum requires careful selection of open space with good ventilation and abundant water resources or harvested rice fields as ideal planting sites. During the planting process, a key step is to make planting holes about 5-6 cm deep in the soil, and then place the appropriate amount of Ganoderma lucidum spores into these holes to promote the growth of Ganoderma lucidum.

[0003] At present, the electric drill is widely used as the main tool for opening holes for Ganoderma lucidum cultivation in the market. It is popular because of its convenient operation and high efficiency. However, the use of electric drills is also accompanied by a series of limitations that cannot be ignored. First of all, as an electric tool, the operation of the electric drill is inevitably accompanied by energy consumption problems, which is particularly prominent in outdoor operations. Due to the complex and changeable outdoor environment, it is often difficult to ensure continuous power supply, which limits the scope of use of electric drills. Secondly, the electric drill is equipped with heavy components such as motors, which makes it heavier overall weight and inconvenient to carry and move. This shortcoming is particularly obvious in the process of Ganoderma lucidum cultivation, which requires frequent changes in planting sites.

[0004] On the other hand, there are also some hole-making tools on the market that do not require electric drive and can be made by manually applying pressure to vertically insert into the soil. These tools can indeed play a certain role when facing soft soil. However, when the soil texture is relatively hard, it becomes extremely difficult to insert vertically, which requires a lot of manpower and may even affect the cultivation effect of Ganoderma lucidum due to the inability to effectively make holes. Therefore, this type of tool also has great limitations in the application environment. Summary of the invention

[0018] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0019] Example The hole-opening device for growing ganoderma lucidum described in this embodiment is as follows: Figure 1 , Figure 5 and Figure 6 As shown, it includes a supporting sleeve 1, in which a push rod 16 independent of the supporting sleeve is installed, and a drill bit 5 is installed at the lower end of the push rod 16. A through groove communicating with the inside and outside is opened on the supporting sleeve 1, and a collar 13 limited to free rotation is mounted on the push rod 16. A cross bar 15 that can slide up and down along the slide groove is fixed on the collar 13, and one end of the cross bar 15 passes through the through groove and is located on the outside of the supporting sleeve 1.

[0020] The lower end of the push rod 16 is provided with a chuck 6 for clamping the drill bit 5; the chuck 6 is a prior art, usually found on electric drills and drilling machines, and is mainly used to clamp various types of drill bits 5. When in use, in order to facilitate the replacement of the drill bit 5, the drill bit 5 is clamped at the lower end of the push rod 16 through the chuck 6; after installation, the center line of the drill bit 5 and the center line of the push rod 16 are on the same straight line.

[0021] There are two through grooves located on the left and right sides of the support sleeve 1, and the cross bar 15 passes through the through grooves and can move up and down along the through grooves. The limiting member includes a first limiting ring 10, which is sleeved on the push rod 16. The bottom of the collar 13 rests on the top of the first limiting ring 10 and is used to push the push rod 16 to move downward. A first limiting ring 10 can also be set on both the upper and lower sides of the collar 13, and the first limiting ring 10 is sleeved on the push rod 16, so that the push rod 16 can be driven to move up and down by the collar 13, and the rotation of the push rod 16 is not restricted. When in use, the cross bar 15 is pressed, and its force acts on the push rod 16 to make it move downward. At the same time, since the push rod 16 and the collar 13 are independent of each other, the push rod 16 rotates during the downward movement, and the collar 13 is stationary. In addition, during the production process, a bearing can be installed between the collar 13 and the push rod 16 to reduce the friction between the two.

[0022] The working end of the cross bar 15 is fixed with a handle 14. When in use, the operator holds the handles 14 on both sides with both hands and applies pressure. During production, a threaded connection can be set between the cross bar 15 and the collar 13 to facilitate disassembly and installation during the production process.

[0023] like Figure 1 , Figure 2 and Figure 6As shown, the push rod 16 is provided with at least two spiral grooves 8 distributed along the length direction of the push rod 16, and the spiral grooves 8 are spiral-shaped; freely rolling balls 7 are arranged in the spiral grooves 8, and a ball groove for limiting the movement of the balls 7 is provided on the inner side wall of the support sleeve 1, and the balls 7 are located in the ball grooves.

[0024] The spiral grooves 8 of the present embodiment are two. When in use, since the ball 7 is in the ball groove and its position remains unchanged, when the push rod 16 is subjected to pressure, the ball 7 guides the spiral grooves 8, so that the push rod 16 starts to rotate, and the rotation of the push rod 16 drives the drill bit 5 to rotate.

[0025] The push rod 16 is guided to rotate by the ball 7, which can effectively reduce the friction between the two and make the push rod 16 easier to rotate.

[0026] A top cover 12 is installed at the upper end of the support sleeve 1, and a reset belt 11 is installed between the top cover 12 and the upper end of the push rod 16. The reset belt 11 is made of elastic material; the reset belt 11 is generally a tightening belt. After pressing the push rod 16 downward, the push rod 16 moves upward through the pulling force of the surgical belt, thereby resetting.

[0027] like Figure 6 As shown, an inner lining tube 9 is fixed inside the support sleeve 1, and the lower end of the push rod 16 independently passes through the inner lining tube 9. A ball groove is opened on the inner wall of the inner lining tube 9, and the ball 7 is located in the ball groove and can rotate freely; the push rod 16 fits with the inner wall of the inner lining tube 9; the inner lining tube 9 can increase the stability of the push rod 16 and reduce shaking.

[0028] A second limiting ring 2 for limiting the shaking of the drill bit 5 is fixed at the lower end of the support sleeve 1, and the drill bit 5 independently passes through the inner ring of the second limiting ring 2; the second limiting ring 2 improves the overall stability of the drill bit 5 during use and prevents it from shaking.

[0029] like Figure 5 and Figure 6 As shown, a material box 18 is installed on the outer wall of the support sleeve 1, and the material box 18 is fixed on the support sleeve 1 through a clamp 17. The clamp 17 is an existing product and is often used to fix some components on a rod-shaped component. In addition, the material box 18 can also be directly welded to the support sleeve 1.

[0030] A discharge pipe 20 is fixed to the bottom of the material box 18, and the discharge port of the discharge pipe 20 is located at the lower end of the support sleeve 1. A discharge hole 19 communicating with the inside and outside is arranged between the discharge pipe 20 and the bottom of the material box 18. When in use, the material box 18 is used to store the ganoderma lucidum spores. After the drill bit 5 completes the hole-making work, the ganoderma lucidum spores enter the discharge pipe 20 from the discharge hole 19, and appear at the lower end of the support sleeve 1 along the discharge pipe 20, and enter the newly-made planting hole. This allows the sowing of spores to be completed as soon as the hole is made, greatly improving the efficiency of ganoderma lucidum planting.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a valve plate 27 is provided at the bottom of the material box 18 corresponding to the discharge hole 19, and a through hole communicating with each other is provided on the valve plate 27. A spring sheet 23 is installed between one side of the valve plate 27 and the inner side wall of the material box 18 to push the through hole and the discharge hole 19 to be staggered with each other, and the valve plate 27 fits the bottom of the material box 18; the support sleeve 1 is provided with a first slide groove communicating with the inside and outside, and the material box 18 is provided with a second slide groove communicating with the first slide groove, and the first slide groove and the second slide groove are provided with the same connecting block 26 that slides left and right; one side of the connecting block 26 is fixed on the valve plate 27, and a shifting block 25 is fixed on the other side thereof, and the shifting block 25 is located in the support sleeve 1, and a shifting rod 24 that pushes the shifting block 25 to slide left and right is fixed on the chuck 6. This section as a whole constitutes a valve assembly for controlling the opening and closing of the discharge hole 19.

[0032] When the spring is in the natural state, the through hole and the discharge hole 19 are staggered with each other, indicating that the discharge hole 19 is in the closed state, and the connecting block 26 is located in the middle of the first slide groove and the second slide groove. At this time, the connecting block 26 can slide to the left or right, and the lever 24 is located at the right upper and oblique side of the lever block 25. When the push rod 16 is pressed and rotates during the downward movement, the push rod 16 drives the clamping head 6 to rotate counterclockwise, and the lever 24 will eventually touch the right side of the lever block 25, forming a mutual constraint between the two, and the push rod 16 continues to rotate, and the lever 24 will continue to rotate counterclockwise and move downward at the same time, which is specifically analyzed into two working processes. The counterclockwise rotation of the lever 24 will cause the valve plate 27 to slide to the left, and the through hole is away from the discharge hole 19, and the discharge hole 19 is still in the closed state; the downward movement trajectory of the lever 24 will eventually be lower than the horizontal height of the lever block 25. At this time, the lever block 25 is no longer constrained by the retracting lever 24, and the valve plate 27 is reset to the initial state under the action of the spring sheet 23. This process will not cause the discharge hole 19 to open, and the spores will not leak out. Its main purpose is to enable the shifting rod 24 to pass through the shifting block 25 and keep the discharge hole 19 closed.

[0033] After the drill bit 5 completes the hole drilling, the push rod 16 moves upward under the reset belt 11 or manually driven, and resets to the initial state. At this time, the lever 24 is an activity trajectory of upward and clockwise rotation. During the activity, the lever 24 will collide with the left side of the lever block 25, causing the lever block 25 to slide to the right. The valve plate 27 slides to the right through the connection of the connecting block 26. At this time, the through hole on the valve plate 27 will form a temporary connection with the discharge hole 19, and the spores in the material box 18 will leak out from the discharge hole 19 and enter the discharge pipe 20. The rod 24 will eventually reach the level of the shift block 25 under the rotation of the push rod 16, and a brief collision will be formed between the shift block 25 and the shift rod 24, causing the valve plate 27 to slide to the right briefly. When the shift block 25 loses the constraint of the shift rod 24, the valve plate 27 is reset to the left and right of the spring sheet 23, and the discharge hole 19 is closed. That is, this brief process causes the discharge hole 19 to be briefly opened, and a certain amount of spores flow out of the material box 18 and finally fall into the planting hole that has just been drilled, completing the planting of Ganoderma lucidum spores, thereby improving work efficiency.

[0034] The discharge port of the discharge pipe 20 is located at the lower end of the support sleeve 1. The reason why the push rod 16 opens the valve plate 27 during the reset process is that the planting hole has been completed at this time, and the drill bit 5 has been separated from the planting hole. As soon as the drill bit 5 is separated from the planting hole, the lever 24 collides with the shift block 25, causing the spores to leak out of the material box 18 and be introduced into the planting hole through the discharge pipe 20. The overall working process is completed in one go, and the opening of the valve plate 27 does not require additional operating steps, making the working process more convenient and quick. To achieve this purpose, the height of the lever 24 in the initial state can only be just higher than the horizontal height of the shift block 25, otherwise the push rod 16 will cause the lever 24 to collide with the shift block 25 in advance during the reset process, and the drill bit 5 will not be separated from the planting hole when the spores leak out.

[0035] like Figure 2 As shown, the discharge port of the discharge pipe 20 can be slightly inclined toward one side of the drill bit 5, so that the spores can just enter the planting hole through the inclined discharge port after the drill bit 5 just comes out of the planting hole.

[0036] A retaining ring 4 is fixed at the lower end of the support sleeve 1. The retaining ring 4 is provided with an opening communicating with the inside and outside. The discharge port of the discharge pipe 20 passes through the opening and is located at the retaining ring 4. Two symmetrically distributed foot pedals 3 are fixed on the retaining ring 4. The bottom of the retaining ring 4 is lower than the horizontal height of the lower end of the drill bit 5. After the Ganoderma lucidum spores come out of the discharge port of the discharge pipe 20, there is enough space to enter the planting hole without being blocked by the drill bit 5. The retaining ring 4 can also prevent the spores from spreading so that they can fall into the planting hole more concentratedly.

[0037] During the drilling process, the worker's feet step on the foot pedal 3, which helps to improve the stability of the drilling. At the same time, the foot pedal 3 increases the contact area with the ground to prevent the lower end of the support sleeve 1 from sinking into the soil easily when the soil is soft.

[0038] like Figure 4 As shown, a limiting plate 21 is fixed to the bottom of the material box 18 to limit the valve plate 27 to slide left and right. The limiting plate 21 allows the valve plate 27 to slide left and right.

[0039] A first baffle 22 is fixed between the top of the limit plate 21 and the inner side wall of the material box 18 to prevent the material from entering the left side of the valve plate 27, and a second baffle 28 is arranged directly above the spring sheet 23 to prevent the material from entering the active area of ​​the spring sheet 23. The first baffle 22 cooperates with the limit plate 21 to prevent spores from entering the active space on the left side of the valve plate 27 and hindering the valve plate 27 from moving leftward. The second baffle 28 cooperates with the limit plate 21 and forms a closed space with the inner side wall of the material box 18, so that the spores cannot reach the working area of ​​the spring sheet 23 and affect its work. In addition, the left and right ends of the spring sheet 23 need to be connected to the valve plate 27 and the inner side wall of the material box 18 respectively to realize the reset work of the valve plate 27 after sliding left and right.

[0040] In actual use, the push rod 16 is moved downward by pressing the cross bar 15, and at the same time, the push rod 16 rotates in the process of moving downward with the cooperation of the ball 7 and the spiral groove 8, thereby driving the drill bit 5 to rotate, saying goodbye to the use environment restrictions caused by the rotation of the electric drive drill bit 5, and at the same time, it is more labor-saving than vertical insertion. In addition, after abandoning some components such as electric drive, the counterweight is reduced, making it more convenient to carry, and the application range and applicable environment are wider. In addition, at the last moment of the reset of the push rod 16, the spores are leaked from the discharge hole 19 through the cooperation of the lever 24 and the block 25, and the sowing of Ganoderma lucidum spores can be completed without additional operation steps, thereby improving work efficiency.
