Description

Technical Field

[0001] The present invention relates to the field of edible fungus cultivation, and in particular to a single-row multi-hole self-adaptive fixed-depth punching device. Background Art

[0002] Log cultivation is an important method for cultivating edible fungi. When using log cultivation, a series of inoculation holes must be pre-machined on the outer surface of the log to inoculate the edible fungi. Since the inoculation holes are distributed on different sides of the log, a rotatable clamp is usually used to clamp the log from both ends when machining these inoculation holes. To facilitate the inoculation equipment in subsequent processes to extend into the inoculation holes to inoculate the fungi, it is usually desired that the inoculation holes be arranged along the radial direction of the log. However, since the diameters of the logs are not uniform, the clamp cannot ensure that its own rotation axis coincides with the axis of the log when clamping the log. When the log rotates a certain angle with the clamp, the extension line of the drill bit feed direction no longer coincides with the axis of the log. In this case, the inoculation holes machined will no longer be along the radial direction of the log. When inoculating the fungi into such inoculation holes, the log needs to be frequently moved horizontally to align the inoculation holes with the inoculation equipment to complete the fungi inoculation, which seriously affects the efficiency of fungi inoculation. Summary of the Invention

[0003] The present invention provides a single-row multi-hole adaptive fixed-depth punching device, which improves the problem that the inoculation holes processed by the punching equipment in the prior art deviate from the radial direction of the log, and can make the processed inoculation holes along the radial direction of the log.

[0004] To achieve the above objectives, the present invention provides a single-row multi-hole adaptive fixed-depth punching device, comprising:

[0005] guide;

[0006] A drilling assembly, wherein the number of the drilling assemblies is multiple, and the drilling assembly includes a drill bit and a slider, the slider is slidably connected to the guide rail, and the drill bit is rotatably connected to the end of the slider along the extension direction of the guide rail;

[0007] a positioning assembly connected to the drill bit, the positioning assembly comprising two positioning portions, wherein the angle between the extending direction of the positioning portions and the extending direction of the drill bit is acute, and the angles between the extending directions of the two positioning portions and the extending direction of the drill bit are equal, and the direction of the line connecting the two positioning portions and the direction of the rotation axis between the drill bit and the slider are acute or right angles;

[0008] A clamping assembly, the clamping assembly being arranged on a side of the drilling assembly away from the guide rail, the clamping assembly being arranged corresponding to the drill bit, the clamping assembly being used to clamp and rotate the wood segment, and the rotation axis direction being parallel to the rotation axis direction between the drill bit and the slider;

[0009] The positioning portion is at least partially closer to the clamping assembly relative to the drill bit along the extension direction of the guide rail. When in use, the single-row, multi-hole, adaptive, fixed-depth drilling device of the present invention is configured such that the clamping assembly clamps both end faces of a log, the drilling assembly and the positioning assembly slide along the guide rail and approach the log, and the positioning portion contacts the log before the drill bit, causing the log to approach the drill bit between the two positioning portions. Since the drill bit connected to the positioning assembly can rotate relative to the slider, as the positioning assembly continues to slide along the guide rail, the positioning assembly will also slide around the surface of the wood segment, and eventually the facing sides of the two positioning parts will contact the outer peripheral surface of the wood segment at the same time. At this time, the side surfaces of the two positioning parts are tangent to the outer peripheral surface of the wood segment, and the direction of the bisector of the angle formed by the two positioning parts, that is, the extension direction of the drill bit, intersects with the axis of the wood segment, so that the inoculation hole processed by the drill bit is along the radial direction of the wood segment, which is beneficial to reduce the number of times the inoculation equipment in the subsequent process adjusts the position of the wood segment when extending into the inoculation hole to inoculate the bacteria, thereby improving the efficiency of bacteria inoculation.

[0010] As an optional technical solution, the drilling assembly further includes a connecting portion, the connecting portion is rotatably connected to the slider, and the drill bit is slidably connected to the connecting portion perpendicular to the axis of rotation of the connecting portion and the slider. Since the log is clamped by the clamping assembly and is restricted from moving in the horizontal direction, when the positioning assembly slides relatively significantly around the outer peripheral surface of the log, the positioning assembly needs to rely on the sliding of the drill bit along the connecting portion to maintain contact with the outer peripheral surface of the log, otherwise it can only rely on the fitting clearance between the components and the elastic deformation to slide slightly. It can be seen that this technical solution can increase the sliding amplitude of the positioning assembly, so that the single-row multi-hole adaptive fixed-depth punching device can process inoculation holes along the radial direction of the log on logs with a wider diameter range.

[0011] As an optional technical solution, the drilling assembly further includes an elastic member, which abuts against the side of the drill bit close to the slider along the extension direction of the drill bit. After the positioning assembly has slid significantly around the outer peripheral surface of the log, the extension direction of the drill bit deviates to a large extent from the extension direction of the guide rail, which reduces the efficiency of the feed movement of the drill bit driven by the force along the guide rail, affecting the drilling efficiency. Since the elastic member is arranged along the extension direction of the drill bit, it can supplement the driving force in the feed movement direction of the drill bit, drive the drill bit to drill into the log, and process the inoculation hole. It can be seen that this technical solution is conducive to improving the drilling efficiency of the single-row multi-hole adaptive fixed-depth drilling device.

[0012] As an optional technical solution, the drilling assembly further includes a stopper that is adjustably mounted on the outer circumference of the drill rod of the drill bit along the extension direction of the drill bit. When the drill bit penetrates the log to a certain depth, such that the stopper contacts the surface of the log, the stopper prevents the drill bit from drilling further, thereby ensuring that the single-row multi-hole adaptive fixed-depth drilling device drills holes to the same depth each time.

[0013] As an optional technical solution, the positioning assembly further comprises a guide rod that is slidably connected to the drill bit along the direction in which the drill bit extends, and the positioning portion is connected to the guide rod. The guide rod allows the positioning portion to be further away from the drill bit, allowing logs of different diameters to be first secured and aligned by the two positioning portions before contacting the drill bit to form inoculation holes, thereby improving the adaptability of the single-row multi-hole adaptive fixed-depth drilling device to logs of varying diameters.

[0014] As an optional technical solution, there are two guide rods, spaced apart along a line connecting the two positioning portions. The positioning assembly further includes a force sensor connected to the guide rods for detecting axial forces acting on the guide rods. The force sensor detects the axial forces acting on the guide rods, thereby determining contact between the log and the two positioning portions and, therefore, whether the extension direction of the drill bit intersects the axis of the log.

[0015] As an optional technical solution, the guide rail, the drilling assembly, and the positioning assembly constitute a punching system. Multiple punching systems are provided, and the guide rails of the multiple punching systems are arranged in parallel and spaced apart. The single-row, multi-hole, adaptive, fixed-depth punching device of this technical solution can simultaneously process multiple inoculation holes in a log, thereby improving punching efficiency.

[0016] As an optional technical solution, the drilling assembly further includes an abutment portion, one end of which is connected to the slider and the other end of which extends away from the guide rail;

[0017] The single-row, multi-hole, adaptive fixed-depth punching device also includes a drive assembly, which includes a drive rod, a rotating shaft, and a first connecting rod. The drive rod is arranged along the direction of the line connecting the multiple guide rails, and the drive rod is arranged on the side of the abutment portion facing the drill bit, and the abutment portion abuts the drive rod; the rotating shaft is arranged parallel to the drive rod, and one side of the first connecting rod is connected to the drive rod and the other side is connected to the rotating shaft. When the single-row, multi-hole, adaptive fixed-depth punching device of this technical solution is in use, the rotating shaft rotates, causing the first connecting rod to drive the drive rod downward. The drilling assembly loses the constraint of the drive rod and can approach the log under the action of gravity and start drilling from the surface of the log. By adjusting the drill bit length and other means, inoculation holes of the same depth can be drilled. After drilling is completed, the rotating shaft rotates in the opposite direction, causing the drive rod to abut the abutment portion, thereby resetting multiple drilling systems at once. The single-row multi-hole adaptive fixed-depth punching device of the present technical solution does not require a separate driving source to be provided for each of the punching systems, which is beneficial to reducing the manufacturing and use costs of the single-row multi-hole adaptive fixed-depth punching device.

[0018] As an optional technical solution, the drive assembly further includes a handle and a second connecting rod, one end of the second connecting rod being connected to the rotating shaft, the angle between the line connecting the end of the second connecting rod and the rotating shaft and the line connecting the end of the first connecting rod facing away from the rotating shaft and the rotating shaft being an obtuse angle or a right angle, and a counterweight being provided at the end of the second connecting rod; and the handle being connected to the rotating shaft. The handle can be used to manually control the rise and fall of the drive rod, thereby controlling the switching of the single-row multi-hole adaptive fixed-depth punching device between the punching state and the reset state, which is conducive to reducing the manufacturing and use costs of the single-row multi-hole adaptive fixed-depth punching device. The counterweight can reduce the difficulty of operating the handle, thereby saving labor.

[0019] As an optional technical solution, a mounting frame is further included, comprising a horizontal beam and two longitudinal beams, the two longitudinal beams being arranged in parallel, the ends of the horizontal beam being connected to the ends of the two longitudinal beams on the same side, the guide rail being mounted on the horizontal beam, and the clamping assembly being mounted on the longitudinal beam. The mounting frame of this technical solution forms a door-like structure, facilitating the installation of a conveyor belt or other conveying device under the horizontal beam to transport the logs, thereby improving the efficiency of drilling large quantities of logs.

[0020] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0021] The single-row multi-hole adaptive fixed-depth drilling device of the present invention includes a guide rail, a multi-drilling assembly, a positioning assembly and a clamping assembly. The drilling assembly contains a drill bit and a slider, the slider is slidably connected to the guide rail, and the drill bit is rotatably connected to the end of the slider; the positioning assembly is connected to the drill bit, and has two positioning parts whose extension directions are at equiacute angles to the drill bit, and the line connecting the two positioning parts is at an acute angle or a right angle to the drill bit and the slider shaft; the clamping assembly is set corresponding to the drill bit. When in use, the clamping assembly clamps the two ends of the log, and the drilling and positioning assembly approaches the log along the guide rail. The positioning part first contacts the log and brings the log close to the drill bit, and the positioning assembly slides around the surface of the log. The side surfaces of the two positioning parts are tangent to the outer peripheral surface of the log, so that the extension direction of the drill bit intersects with the axis of the log, so that the drilled inoculation hole is along the radial direction of the log, which can reduce the number of times the position of the log is adjusted during inoculation and improve inoculation efficiency.

[0036] Example 1

[0037] This embodiment provides a single-row multi-hole adaptive fixed-depth drilling device, which includes a guide rail 1, a drilling assembly 2, a positioning assembly 3 and a clamping assembly 4. There are multiple drilling assemblies 2, and the drilling assembly 2 includes a drill bit 21 and a slider 22. The slider 22 is slidably connected to the guide rail 1, and the drill bit 21 is rotatably connected to the end of the slider 22 along the extension direction of the guide rail 1; the positioning assembly 3 is connected to the drill bit 21, and the positioning assembly 3 includes two positioning parts 31. The extension direction of the positioning part 31 and the extension direction of the drill bit 21 are at an acute angle, and the extension direction of the two positioning parts 31 and the extension direction of the drill bit 21 are equal. The direction of the connecting line between the two positioning parts 31 and the direction of the rotating shaft 52 between the drill bit 21 and the slider 22 are at an acute angle or a right angle; the clamping assembly 4 is arranged on the side of the drilling assembly 2 away from the guide rail 1, and the clamping assembly 4 is arranged corresponding to the drill bit 21. The clamping assembly 4 is used to clamp and rotate the wood segment, and the direction of the rotating shaft 52 is parallel to the direction of the rotating shaft 52 between the drill bit 21 and the slider 22; wherein, the positioning part 31 is at least partially closer to the clamping assembly 4 relative to the drill bit 21 along the extension direction of the guide rail 1.

[0038] When in use, the single-row, multi-hole, adaptive, fixed-depth drilling device of the present invention causes the clamping assembly 4 to clamp the two end faces of a log, while the drilling assembly 2 and positioning assembly 3 slide along the guide rail 1 and approach the log. The positioning portion 31 contacts the log before the drill bit 21, and the log is brought closer to the drill bit 21 between the two positioning portions 31. Because the drill bit 21 connected to the positioning assembly 3 can rotate relative to the slider 22, as the positioning assembly 3 continues to slide along the guide rail 1, the positioning assembly 3 will also slide around the surface of the log, eventually causing the facing sides of the two positioning portions 31 to simultaneously contact the outer peripheral surface of the log. At this time, the side faces of the two positioning portions 31 are tangent to the outer peripheral surface of the log, and the direction of the angle bisector formed by the two positioning portions 31, i.e., the extension direction of the drill bit 21, intersects the axis of the log. This allows the inoculation hole machined by the drill bit 21 to be radially aligned with the log, which helps reduce the number of times the inoculation equipment needs to adjust the position of the log when inserting the inoculation device into the inoculation hole to inoculate the bacteria in the subsequent process, thereby improving the efficiency of the inoculation.

[0039] Example 2

[0040] On the basis of Example 1, the drilling assembly 2 also includes a connecting portion 23, which is rotatably connected to the slider 22, and the drill bit 21 is slidably connected to the connecting portion 23 perpendicular to the direction of the rotating shaft 52 of the connecting portion 23 and the slider 22. Since the log is clamped by the clamping assembly 4 and is restricted from moving in the horizontal direction, when the positioning assembly 3 slides around the outer peripheral surface of the log to a large extent, the positioning assembly 3 needs to rely on the sliding of the drill bit 21 along the connecting portion 23 to maintain contact with the outer peripheral surface of the log. Otherwise, it can only rely on the matching clearance between the components and the elastic deformation to slide slightly. It can be seen that this embodiment can increase the sliding amplitude of the positioning assembly 3, so that the single-row multi-hole adaptive fixed-depth punching device can process inoculation holes along the radial direction of the log on logs with a wider diameter range.

[0041] Specifically, a guide rail or a slide groove may be provided on the connecting portion 23, and the drill bit is mounted on the guide rail or the slide groove to achieve a sliding connection between the drill bit and the connecting portion.

[0042] As an optional embodiment, the drilling assembly 2 also includes an elastic member 24, which abuts against the side of the drill bit 21 close to the slider 22 along the extension direction of the drill bit 21. After the positioning assembly 3 slides significantly around the outer peripheral surface of the log, the extension direction of the drill bit 21 deviates from the extension direction of the guide rail 1 to a large extent, which reduces the efficiency of the feed movement of the drill bit 21 driven by the force along the guide rail 1, affecting the drilling efficiency. Since the elastic member 24 is arranged along the extension direction of the drill bit 21, it can supplement the driving force in the feed movement direction of the drill bit 21, drive the drill bit 21 to drill into the log, and process the inoculation hole. It can be seen that this embodiment is conducive to improving the drilling efficiency of the single-row multi-hole adaptive fixed depth punching device. The elastic member 24 can be a pad-shaped element made of a spring, rubber or silicone elastic material, etc., and this embodiment is not limited here.

[0043] As an optional embodiment, the drilling assembly 2 further includes a stopper 25, which is adjustably mounted on the outer circumference of the drill rod of the drill bit 21 along the extension direction of the drill bit 21. When the drill bit 21 penetrates the log to a certain depth, causing the stopper 25 to contact the surface of the log, the stopper 25 prevents the drill bit 21 from drilling further, thereby ensuring that the single-row multi-hole adaptive fixed-depth drilling device drills holes to the same depth each time.

[0044] As an optional embodiment, the positioning assembly 3 further includes a guide rod 32, which is slidably connected to the drill bit 21 along the extension direction of the drill bit 21, and the positioning portion 31 is connected to the guide rod 32. The guide rod 32 allows the positioning portion 31 to be further away from the drill bit 21, so that logs of different diameters can be first fixed and fitted by the two positioning portions 31 before contacting the drill bit 21 to process the inoculation holes. This helps improve the adaptability of the single-row multi-hole adaptive fixed-depth drilling device to logs of different diameters.

[0045] As an optional embodiment, two guide rods 32 are provided, spaced apart along the line connecting the two positioning portions 31. The positioning assembly 3 also includes a force sensor connected to the guide rods 32 for detecting the axial force acting on the guide rods 32. The force sensor detects the axial force acting on the two guide rods 32, thereby determining the contact between the log and the two positioning portions 31 and, therefore, whether the extension direction of the drill bit 21 intersects the axis of the log.

[0046] As an optional embodiment, the guide rail 1, drilling assembly 2, and positioning assembly 3 constitute a punching system. There are multiple punching systems, and the guide rails 1 of the multiple punching systems are arranged in parallel and spaced apart. The single-row multi-hole adaptive fixed-depth punching device of this embodiment can simultaneously process multiple inoculation holes on a log, which is beneficial to improving punching efficiency.

[0047] As an optional embodiment, the drilling assembly 2 further includes an abutment portion 26 , one end of the abutment portion 26 is connected to the slider 22 , and the other end extends away from the guide rail 1 ;

[0048] The single-row, multi-hole, adaptive fixed-depth drilling device also includes a drive assembly 5, which includes a drive rod 51, a rotating shaft 52, and a first connecting rod 53. The drive rod 51 is arranged along the line connecting the multiple guide rails 1 and is located on the side of the abutment portion 26 facing the drill bit 21, with the abutment portion 26 abutting the drive rod 51. The rotating shaft 52 is arranged parallel to the drive rod 51, and the first connecting rod 53 is connected to the drive rod 51 on one side and to the rotating shaft 52 on the other side. When the single-row, multi-hole, adaptive fixed-depth drilling device of this embodiment is in use, the rotating shaft 52 rotates, causing the first connecting rod 53 to move the drive rod 51 downward. Without the constraint of the drive rod 51, the drilling assembly 2 can approach the log under the action of gravity and begin drilling from the log surface. By adjusting the length of the drill bit 21 or using the limiter 25 described above, inoculation holes of the same depth can be drilled. After drilling is completed, the rotating shaft 52 rotates in the opposite direction, causing the drive rod 51 to abut the abutment portion 26, thereby resetting multiple drilling systems at once. The single-row multi-hole adaptive fixed-depth punching device of this embodiment does not need to provide a separate driving source for each punching system, which is beneficial to reducing the manufacturing and use costs of the single-row multi-hole adaptive fixed-depth punching device.

[0049] As an optional embodiment, the drive assembly 5 also includes a handle 55 and a second connecting rod 54. One end of the second connecting rod 54 is connected to the rotating shaft 52. The angle between the line connecting the end of the second connecting rod 54 and the rotating shaft 52 and the line connecting the end of the first connecting rod 53 facing away from the rotating shaft 52 and the rotating shaft 52 is obtuse or straight. A counterweight 541 is provided at the end of the second connecting rod 54. The handle 55 is connected to the rotating shaft 52. The handle 55 can be used to manually control the raising and lowering of the drive rod 51, thereby controlling the switching of the single-row multi-hole adaptive fixed-depth punching device between the punching state and the reset state, which helps to reduce the manufacturing and use costs of the single-row multi-hole adaptive fixed-depth punching device. The counterweight 541 can reduce the difficulty of operating the handle 55, thereby saving labor.

[0050] In addition, a driving element such as a rotary cylinder or a motor may also be used to drive the rotating shaft 52 to rotate. In practice, the selection should be made according to actual needs, and this embodiment does not limit this.

[0051] As an optional embodiment, a mounting frame is further included, comprising a crossbeam 6 and two longitudinal beams 7. The two longitudinal beams 7 are arranged in parallel, with the ends of the crossbeam 6 connected to the ends of the two longitudinal beams 7 on the same side. The guide rail 1 is mounted on the crossbeam 6, and the clamping assembly 4 is mounted on the longitudinal beams 7. The mounting frame of this embodiment has a door-like structure, which facilitates the installation of a conveyor belt or other conveying device under the crossbeam 6 to transport the logs, thereby improving the efficiency of drilling large quantities of logs.

[0052] Example 3

[0053] This embodiment discloses a method for using a single-row multi-hole adaptive fixed-depth punching device, which is applied to the single-row multi-hole adaptive fixed-depth punching device described in Example 2, and includes the following steps:

[0054] S1: Clamp the log into the clamping assembly;

[0055] S2: operating the handle 55 to move the punching system toward the log, so that the two positioning parts 31 contact the outer peripheral surface of the log;

[0056] S3: The punching system continues to move, and the positioning portion 31 abuts against the outer peripheral surface of the log, causing the connecting portion 23 to rotate so that the facing sides of the two positioning portions 31 are in contact with the outer peripheral surface of the log;

[0057] S4: The drill bit 21 rotates to machine the inoculation hole on the outer peripheral surface of the log until the limit piece 25 abuts against the log, preventing the drill bit 21 from going deeper;

[0058] S5: Operate the handle 55 to move the driving rod 51 upward to abut against the abutment portion 26, thereby resetting the punching system. The clamping assembly 4 drives the log to rotate, exposing the new location to be punched below the punching system.

[0059] S6: Repeat steps S2-S5 until all inoculation holes of the wood segment are processed;

[0060] S7: Remove the log from the clamping assembly 4 and transfer it to the subsequent process.

[0061] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0062] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
