Description

Technical Field

[0001] The 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 need to be processed on the outer surface of the log in advance to inoculate 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 of the log when processing these inoculation holes. In order to facilitate the inoculation equipment in the subsequent process to extend into the inoculation hole to inoculate the fungi, it is usually expected that the inoculation hole is set along the radial direction of the log. However, since the diameter of the log is not consistent, 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 feed direction no longer coincides with the axis of the log. In this case, the inoculation hole processed will no longer be along the radial direction of the log. When inoculating fungi into such an inoculation hole, it is necessary to frequently move the log in the horizontal direction to align the inoculation hole with the inoculation equipment coaxially 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 object, the present invention provides a single-row multi-hole self-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 comprises a drill bit and a slider, wherein 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, the positioning assembly is connected to the drill bit, the positioning assembly comprises two positioning parts, the extending direction of the positioning parts forms an acute angle with the extending direction of the drill bit, and the extending directions of the two positioning parts form an equal angle with the extending direction of the drill bit, and the direction of the connecting line between the two positioning parts forms an acute angle or a right angle with the direction of the rotating shaft between the drill bit and the slider;

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

[0009] The positioning part is at least partially closer to the clamping assembly relative to the drill bit along the extension direction of the guide rail. When the single-row multi-hole adaptive fixed-depth punching device of the present invention is used, the clamping assembly clamps the two end faces of the wood segment, the drilling assembly and the positioning assembly slide along the guide rail and approach the wood segment, the positioning part will contact the wood segment before the drill bit, and the wood segment will be close to the drill bit between the two positioning parts. 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 finally the side surfaces of the two positioning parts facing each other 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 the bacteria inoculation.

[0010] As an optional technical solution, the drilling assembly also 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 matching clearance between the components and the elastic deformation to slide slightly. It can be seen that the present 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 a side of the drill bit close to the slider along the extension direction of the drill bit. When the positioning assembly slides relatively 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 the present 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, which is adjustable and sleeved on the outer periphery of the drill rod of the drill along the extension direction of the drill. When the drill drills into the wood segment to a certain depth, so that the stopper contacts the surface of the wood segment, the stopper prevents the drill from going deeper, so 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 includes a guide rod, which is slidably connected to the drill bit along the extension direction of the drill bit, and the positioning part is connected to the guide rod. The guide rod allows the positioning part to be further away from the drill bit, so that wood segments with different diameters can be first fixed and fitted by the two positioning parts, and then contact the drill bit to process the inoculation holes, which is conducive to improving the adaptability of the single-row multi-hole adaptive fixed-depth punching device to wood segments with different diameters.

[0014] As an optional technical solution, the number of the guide rods is two, and the two guide rods are spaced apart along the direction of the line between the two positioning parts. The positioning assembly also includes a force sensor, which is connected to the guide rod and is used to obtain the axial force of the guide rod. The force sensor obtains the axial force of the two guide rods, and can determine the contact between the wood segment and the two positioning parts, thereby determining whether the extension direction of the drill bit intersects with the axis of the wood segment.

[0015] As an optional technical solution, the guide rail, the drilling assembly and the positioning assembly form a punching system, and the number of the punching systems is multiple, 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 process multiple inoculation holes on the log at the same time, which is conducive to improving the 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 self-adaptive fixed-depth punching device also includes a driving assembly, which includes a driving rod, a rotating shaft and a first connecting rod. The driving rod is arranged along the connecting line direction between the plurality of guide rails, and the driving rod is arranged on the side of the abutment portion facing the drill bit, and the abutment portion abuts against the driving rod; the rotating shaft is arranged parallel to the driving rod, and one side of the first connecting rod is connected to the driving rod and the other side is connected to the rotating shaft. When the single-row multi-hole self-adaptive fixed-depth punching device of the technical solution is in use, the rotating shaft rotates, so that the first connecting rod drives the driving rod to move downward, and the drilling assembly loses the constraint of the driving rod, and can approach the wood segment under the action of gravity, and start drilling from the surface of the wood segment. By adjusting the length of the drill bit and other means, inoculation holes of the same depth can be drilled. After the drilling is completed, the rotating shaft rotates in the opposite direction, so that the driving rod abuts against the abutment portion, thereby resetting multiple drilling systems at one time. The single-row multi-hole adaptive fixed-depth punching device of the present technical solution does not need to provide a separate driving source 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 also includes a handle and a second connecting rod, one end of the second connecting rod is connected to the rotating shaft, the angle between the line connecting the end of the second connecting rod to the rotating shaft and the line connecting the end of the first connecting rod away from the rotating shaft and the rotating shaft is an obtuse angle or a straight angle, and a counterweight is provided at the end of the second connecting rod; the handle is connected to the rotating shaft. The handle can be used to manually control the rise and fall of the driving 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 and achieve the effect of saving labor.

[0019] As an optional technical solution, it also includes a mounting frame, the mounting frame includes a crossbeam and two longitudinal beams, the two longitudinal beams are arranged in parallel, the two ends of the crossbeam are respectively connected to the ends of the two longitudinal beams on the same side, the guide rail is installed on the crossbeam, and the clamping assembly is installed on the longitudinal beam. The mounting frame of this technical solution forms a door-like structure, which is convenient for installing a conveying device such as a conveyor belt on the lower side of the crossbeam to transport the wood segments, which is conducive to improving the efficiency of drilling large quantities of wood segments.

[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 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; the positioning assembly is connected to the drill bit, and has two positioning parts whose extension directions are equi-acute angles with the drill bit, and the line connecting the two positioning parts is an acute angle or a right angle with the drill bit and the slider shaft; the clamping assembly is arranged 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, and 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 the inoculation efficiency.

[0036] Embodiment 1

[0037] This embodiment provides a single-row multi-hole adaptive fixed-depth punching 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 assemblies 2 include 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 form an acute angle, and the extension direction of the two positioning parts 31 and the extension direction of the drill bit 21 The angle is equal, and the direction of the connecting line between the two positioning parts 31 is an acute angle or a right angle with the direction of the rotating shaft 52 between the drill bit 21 and the slider 22; 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 log, 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] The single-row multi-hole self-adaptive fixed-depth punching device of the present invention, when in use, makes the clamping assembly 4 clamp the two end faces of the log, the drilling assembly 2 and the positioning assembly 3 slide along the guide rail 1 and approach the log, the positioning portion 31 will contact the log before the drill bit 21, and make the log approach the drill bit 21 between the two positioning portions 31. Since 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, and finally make the side faces of the two positioning portions 31 facing each other contact the outer peripheral surface of the log at the same time, 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, that is, the extension direction of the drill bit 21, intersects with the axis of the log, so that the inoculation hole processed by the drill bit 21 is along the radial direction of the log, which is conducive to reducing the number of times the inoculation equipment in the subsequent process extends into the inoculation hole to inoculate the bacteria, and improves the efficiency of the bacteria inoculation.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, 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 the fit with the outer peripheral surface of the log, otherwise it can only rely on the matching clearance between the components and the deformation based on elasticity 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 around the outer peripheral surface of the log to a large extent, the extension direction of the drill bit 21 deviates from the extension direction of the guide rail 1 to a large extent, so that the efficiency of the feed movement of the drill bit 21 driven by the force along the guide rail 1 is reduced, 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 cushion-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 adjustable and sleeved on the outer periphery of the drill rod of the drill bit 21 along the extension direction of the drill bit 21. When the drill bit 21 drills into the log to a certain depth, so that the stopper 25 contacts the surface of the log, the stopper 25 prevents the drill bit 21 from drilling further, so that the single-row multi-hole adaptive fixed-depth drilling device has the same depth of drilling 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 wood segments of different diameters can be first fixed and fitted by the two positioning portions 31, and then contact the drill bit 21 to process the inoculation holes, which is conducive to improving the adaptability of the single-row multi-hole adaptive fixed depth punching device to wood segments of different diameters.

[0045] As an optional embodiment, the number of guide rods 32 is two, and the two guide rods 32 are arranged at intervals along the direction of the line between the two positioning parts 31. The positioning assembly 3 also includes a force sensor, which is connected to the guide rod 32. The force sensor is used to obtain the axial force of the guide rod 32. The force sensor obtains the axial force of the two guide rods 32, and can determine the contact between the log and the two positioning parts 31, thereby determining whether the extension direction of the drill bit 21 intersects with the axis of the log.

[0046] As an optional embodiment, the guide rail 1, the drilling assembly 2 and the positioning assembly 3 form a punching system, and the number of the punching systems is multiple, 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 process multiple inoculation holes on the log at the same time, which is conducive to improving the 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 self-adaptive fixed-depth punching device also includes a driving assembly 5, which includes a driving rod 51, a rotating shaft 52 and a first connecting rod 53. The driving rod 51 is arranged along the connecting line direction between the multiple guide rails 1, and the driving rod 51 is arranged on the side of the abutment portion 26 facing the drill bit 21, and the abutment portion 26 abuts against the driving rod 51; the rotating shaft 52 is arranged parallel to the driving rod 51, and one side of the first connecting rod 53 is connected to the driving rod 51 and the other side is connected to the rotating shaft 52. When the single-row multi-hole self-adaptive fixed-depth punching device of this embodiment is in use, the rotating shaft 52 rotates, so that the first connecting rod 53 drives the driving rod 51 to move downward, and the drilling assembly 2 loses the constraint of the driving rod 51, and can approach the log under the action of gravity, and start drilling from the surface of the log. By adjusting the length of the drill bit 21 or using the above-mentioned limit piece 25 and other means, the inoculation hole of the same depth can be drilled. After the drilling is completed, the rotating shaft 52 rotates in the opposite direction, so that the driving rod 51 abuts against the abutment portion 26, thereby resetting multiple drilling systems at one time. 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 driving 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 to the rotating shaft 52 and the line connecting the end of the first connecting rod 53 away from the rotating shaft 52 and the rotating shaft 52 is an obtuse angle or a straight angle, and 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 rise and fall of the driving rod 51, thereby controlling the single-row multi-hole self-adaptive fixed depth punching device to switch between the punching state and the reset state, which is conducive to reducing the manufacturing and use costs of the single-row multi-hole self-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, which includes a crossbeam 6 and two longitudinal beams 7. The two longitudinal beams 7 are arranged in parallel, and the two ends of the crossbeam 6 are respectively connected to the ends of the two longitudinal beams 7 on the same side. The guide rail 1 is installed on the crossbeam 6, and the clamping assembly 4 is installed on the longitudinal beam 7. The mounting frame of this embodiment forms a door-like structure, which is convenient for installing a conveying device such as a conveyor belt on the lower side of the crossbeam 6 to transport the wood segments, which is conducive to improving the efficiency of drilling large quantities of wood segments.
