Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, and more specifically, to a single-row multi-segment wood drilling assembly. Background Technology

[0002] Log cultivation is an agricultural technique that uses wood as a culture medium, mainly used for the cultivation of edible and medicinal fungi such as Ganoderma lucidum, shiitake mushrooms, and wood ear mushrooms. It typically uses logs about 1 meter long for cultivation. Holes are made on the outer surface of the logs, and inoculation is carried out in the holes. The fungi grow by decomposing the logs. Because a natural substrate is used, no pesticides or fertilizers are needed during the growth process, resulting in a pure, natural, and pollution-free green food.

[0003] The process of log cultivation involves multiple steps, including drilling, inoculation, and mycelium growth. Among these, the most labor-intensive step is drilling. Currently, to save manpower and speed up the drilling process, equipment capable of single-row multi-drilling is typically used. However, due to the diversity of logs, including different diameters, curvatures, protrusions and depressions, and even hardening, the drilling methods used do not meet the requirements of log cultivation. Discarding the entire log is wasteful. Therefore, it is necessary to avoid drilling in sections of the log that do not meet the requirements. Existing single-row multi-drilling devices have a fixed drill bit spacing, which can only be achieved through multiple drilling operations, which is time-consuming and cumbersome. Summary of the Invention

[0004] This invention provides a single-row multi-drill segment wood drilling assembly to solve the problems of existing single-row multi-drill segment wood drilling devices being unable to avoid non-compliant segment wood sections in a single drilling operation, resulting in cumbersome operation and long time consumption.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] A single-row multi-segment wood drilling assembly includes a drill bit mounting frame and a drill bit module. The drill bit mounting frame includes several vertically mounted frames, a slide rail mounted on the lower end of the frames, and a sliding module. The drill bit module is mounted on the lower end of the sliding module.

[0007] This invention allows for individual adjustment of drill bit modules by setting slide rails and sliding modules at the lower end of the drill bit mounting frame. This adjustment enables the drill bit modules to avoid non-compliant wood sections before drilling, thus avoiding multiple drilling operations and reducing drilling time.

[0008] Furthermore, the sliding module includes a slider that slides within the slide rail, a guide rod fixedly connected to the lower end of the slider, and a drill bit base sleeved on the guide rod. The distance between the drill bit base and the slider is increased by pulling the drill bit base, thereby facilitating the movement of the slider.

[0009] Furthermore, the slide rail sidewall is provided with several “7”-shaped limiting grooves, and the drill bit base sidewall is provided with limiting blocks, which match the limiting grooves.

[0010] Because drilling requires pressing down and lifting the drill bit module, the drill bit base may be pulled up, causing the drill bit module to deviate and affecting the drilling spacing. By setting a "7"-shaped limiting groove, the limiting block on the drill bit base is embedded into the limiting groove to prevent the drill bit base from being pulled up when pressing down and lifting the drill bit module, and it will not affect the operation of quickly adjusting the position of the drill bit base.

[0011] Furthermore, a tension elastic element is provided between the slider and the drill bit base.

[0012] By utilizing the rebound characteristics of the tension elastic element, the slide rail and the sliding module are locked together. Simply pull up the drill bit base to adjust the position of the slider, and release the pull on the drill bit base. The rebounding tension elastic element will then lock the drill bit base onto the slide rail. The operation is simple and quick, improving the efficiency of adjusting the drilling spacing.

[0013] Furthermore, a handle is provided on the side wall of the drill bit base. The drill bit base can be moved up and down by operating the handle, which is more convenient and less strenuous.

[0014] Furthermore, the grip includes a longitudinal rod fixedly connected to the side wall of the drill bit base, a crossbar fixedly installed at the end of the longitudinal rod, and a connecting rod sleeved between two adjacent crossbars.

[0015] When a certain part of the log is unsuitable for drilling, all the drill holes on that side need to be shifted a certain distance to that side. Therefore, the corresponding drill bit bases need to undergo unlocking (the limit block moves out of the limit groove), shifting, and embedding (the limit block embeds into the limit groove). Operating multiple drill bit bases sequentially is time-consuming and reduces work efficiency. Therefore, by connecting all the crossbars together with connecting rods, synchronous operation can be achieved, saving operation time. At the same time, only the connecting rod corresponding to the unsuitable part of the log needs to be removed, and the drill bit base can be adjusted by operating the crossbars twice, which greatly reduces operation time.

[0016] If multiple defects exist, the movement distances of the drill bit modules are superimposed. If there are two defects on the log section to be drilled next, the log section is divided into sections: Hole 1, Defect 1 Hole 2, Defect 2, and Hole 3, using the defects as dividers. Keeping the Hole 1 section stationary, the drill bit module above Defect 1 needs to be moved a distance 'a' to avoid the Defect 1 section, and the drill bit module above Defect 2 needs to be moved a distance 'b' to avoid the Defect 2 section. The specific operation is as follows: Remove the connecting rod corresponding to the drill bit module above Defect 1, operate the drill bit module above Defect 1 and away from the Hole 1 section, moving it a distance away from the Hole 1 section. Then, confirm the specific value of distance 'b', remove the connecting rod corresponding to the drill bit module above Defect 2, operate the drill bit module above Defect 2 and away from the Hole 2 section, moving it a distance 'b' to ensure that the drill bit modules avoid all defects, so that all drilling meets the requirements for log cultivation. After the drill bit modules have been moved, the removed connecting rods can be reinstalled in their corresponding positions to connect all the drill bit modules, increasing the overall strength of the device and the synchronization of drilling.

[0017] Furthermore, the connecting rod is an arc-shaped tube that is fitted onto the crossbar from top to bottom, and both ends and the bottom end of the connecting rod are open.

[0018] Because the spacing between the drill bit bases changes, the spacing between the crossbars also changes. By using an arc tube to fit over the two adjacent crossbars from above, the problem of the connecting rod not being long enough due to the change in the spacing between the crossbars can be avoided. At the same time, the operation of fitting the arc tube is simpler.

[0019] Furthermore, the connecting rod has first pin holes at both ends, and the crossbar has several second pin holes at both ends. The first pin holes and the second pin holes are fixed together by pins. The first pin holes and the second pin holes are both horizontal and perpendicular to the axis of the crossbar.

[0020] Since the operation of the drill bit base translation requires the operation of the crossbar to perform an axial movement (the limiting block moves within the "7"-shaped limiting groove), a downward press (the limiting block moves out of the limiting groove), and a second axial movement (adjusting the position of the drill bit base to the left or right), it is necessary to limit the connecting rod and the crossbar in the vertical and axial directions. Therefore, the method of opening a pin hole horizontally and perpendicular to the axis of the crossbar is chosen to achieve this.

[0021] Furthermore, reinforcing ribs are provided between the two ends of the slide rail and the frame.

[0022] Because the drill bit mounting bracket is vertically mounted and the slide rail is horizontally mounted, when the drill bit base is located at both ends of the slide rail, the reaction force of the drill bit base on the slide rail is too large during drilling operations, which can easily damage the slide rail. The slide rail is reinforced with reinforcing ribs to enhance its structural strength.

[0023] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0024] (1) The present invention adjusts the drill bit module individually by setting a slide rail and a sliding module at the lower end of the drill bit mounting frame, thereby adjusting the spacing of some drill bit modules, so that the drill bit module can avoid the unacceptable wood section before drilling operation, avoid multiple drilling operations, and reduce the drilling operation time.

[0025] (2) By setting a “7” shaped limiting groove, the limiting block on the drill bit base is embedded into the limiting groove to prevent the drill bit base from being pulled up when the drill bit module is pressed down and raised, and it will not affect the operation of quickly adjusting the position of the drill bit base.

[0026] (3) By leveraging the rebound characteristics of the tension elastic element, the slide rail and the sliding module are locked together. Simply pull up the drill bit base to adjust the position of the slider. When the pull up of the drill bit base is canceled, the rebounding tension elastic element can clamp the drill bit base onto the slide rail. The operation is simple and quick, improving the efficiency of adjusting the drilling spacing.

[0027] (4) Connect all the crossbars together with the connecting rod to achieve synchronous operation and save operation time. At the same time, you only need to remove the connecting rod corresponding to the part of the log that is not suitable for drilling, and the drill bit base can be adjusted by operating the crossbar twice, which greatly reduces the operation time.

[0028] (5) By using the arc tube to fit from above onto two adjacent crossbars, the problem of insufficient connecting rod length caused by changes in the spacing between crossbars can be avoided. At the same time, the operation of fitting the arc tube is simpler. Attached Figure Description

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] Example 1

[0040] This embodiment provides a single-row, multi-segment wood drilling assembly, such as... Figures 1-6 As shown, the device includes a drill bit mounting frame 1 and a drill bit module 2. The drill bit mounting frame 1 includes several vertically mounted frame bodies 101, a slide rail 102 mounted on the lower end of the frame body 101, and a sliding module. The drill bit module 2 is mounted on the lower end of the sliding module. The sliding module includes a slider 301 that slides within the slide rail 102, a guide rod 302 fixedly connected to the lower end of the slider 301, and a drill bit base 303 sleeved on the guide rod 302.

[0041] The slide rail 102 is a closed slide rail with both ends closed to prevent the slider 301 from derailing. Since the slide rail 102 is set with its opening facing downwards, it is preferable to set the opening width of the slide rail 102 to be smaller than the width of the slider 301, thus confining the slider 301 to slide within it. The guide rod 302 extends downwards from the opening below the slide rail 102. Similarly, to prevent the drill bit base 303 from detaching from the guide rod 302, the end of the guide rod 302 and the opening of the drill bit base 303 are preferably provided with limiting structures. The number of frames 101 is determined according to the number of holes required for the log section. Preferably, the number is greater than or equal to the number of holes required for a log section, so as to achieve drilling a single row of holes on the log section in a single operation and avoid secondary drilling in the same row. The drill bit module 2 is installed in a detachable manner at the lower end of the drill bit mounting frame 1 for easy replacement.

[0042] In a more preferred embodiment, the slide rail 102 has a plurality of “7”-shaped limiting grooves 103 on its side wall, and the drill bit base 303 has a limiting block 304 on its side wall, the limiting block 304 matching the limiting grooves 103.

[0043] The number of limiting grooves 103 is determined according to the length of the slide rail 102. Preferably, three or more are provided, one of which is located directly below the frame 101, and the remaining limiting grooves 103 are evenly distributed on both sides of it. The width of the limiting groove 103 is preferably equal to the width of the limiting block 304.

[0044] In a more preferred embodiment, a tension elastic element 4 is provided between the slider 301 and the drill bit base 303. The tension elastic element 4 is preferably a tension spring or an elastic band.

[0045] In a more preferred embodiment, reinforcing ribs 6 are provided between the two ends of the slide rail 102 and the frame 101.

[0046] Example 2

[0047] Based on Example 1, such as Figures 1-6 As shown, a handle is provided on the side wall of the drill bit base 303; the handle includes a longitudinal rod 501 fixedly connected to the side wall of the drill bit base 303, a crossbar 502 fixedly installed at the end of the longitudinal rod 501, and a connecting rod 503 sleeved between two adjacent crossbars 502.

[0048] Preferably, one end of the longitudinal rod 501 is fixedly installed on the center line of the side wall of the drill bit base 303 to ensure that the drill bit base 303 is subjected to uniform force, and the other end is fixedly connected to the middle of the cross rod 502. When the drill bit base 303 is not operated, the axes of all the cross rods 502 are collinear. Preferably, the number of connecting rods 503 is one less than the number of cross rods 502. One connecting rod 503 is installed between every two adjacent cross rods 502. The connecting rods 503 can be connected by means of buckles, bolts or keys, etc., and the connection method is to limit the vertical direction and the axial direction of the cross rods 502 and the connecting rods 503.

[0049] In a more preferred embodiment, the connecting rod 503 is an arc-shaped tube that is fitted onto the crossbar 502 from top to bottom, and both ends and the bottom end of the connecting rod 503 are open.

[0050] The arc tube is preferably a semi-circular arc tube, and its inner diameter is equal to the diameter of the crossbar 502. The length of the connecting rod 503 is preferably the total length of the crossbar 502 plus the distance between two adjacent crossbars 502 in the initial state, so that the connecting rod 503 has a surplus equal to the length of the crossbar 502, reducing the situation where the two ends of the connecting rod 503 cannot be connected to the two adjacent crossbars 502 at the same time when the distance between the drill bit bases 303 increases.

[0051] In a more preferred embodiment, the connecting rod 503 is provided with first pin holes 504 at both ends, and the crossbar 502 is provided with a plurality of second pin holes 505 at both ends, and the first pin holes 504 and the second pin holes 505 are fixed together by pins.

[0052] The first pin hole 504 and the second pin hole 505 are in the same relative position. That is, when the connecting rod 503 is sleeved on the crossbar 502, the first pin hole 504 and the second pin hole 505 are at the same height, which facilitates the insertion of the pin. The first pin hole 504 and the second pin hole 505 have the same diameter. The second pin holes 505 at both ends of the crossbar 502 are symmetrically distributed, and the second pin holes 505 at the same end are evenly spaced. The number of second pin holes 505 is determined according to the requirements.

[0053] In a more preferred embodiment, both the first pin hole 504 and the second pin hole 505 are horizontal and perpendicular to the axis of the crossbar 502.

[0054] Example 3

[0055] Based on Embodiment 2, it further includes several parallel first connecting rods and several parallel second connecting rods mounted on the drill bit mounting frame 1. The first connecting rods and the second connecting rods are of equal length. The middle parts of the first connecting rods and the middle parts of the second connecting rods are rotatably connected. The rotation axes of the first connecting rods and the second connecting rods are fixedly connected to the drill bit mounting frame. The two ends of the first connecting rods are rotatably connected to the ends of two adjacent second connecting rods, and the two ends of the second connecting rods are rotatably connected to the ends of two adjacent first connecting rods.

[0056] Existing devices all have fixed spacing, and the drilling spacing required for cultivating different fungal species varies. For example, the drilling spacing for shiitake mushroom cultivation on logs is 10cm, while the drilling spacing for tremella cultivation on logs is 8cm. Different hole spacings require different drilling equipment, increasing equipment costs. Therefore, a rhomboid linkage mechanism composed of several first and second links is used to make all drill bit mounting frames move synchronously. At the same time, the equal length of the first and second links also ensures that the spacing between the drill bit mounting frames changes synchronously and equally, achieving the goal of equal spacing throughout the process. This not only solves the problem of long operation time when manually adjusting the spacing individually, but also... It can also improve the accuracy of equal spacing; at the same time, some smaller defect sections can be avoided by adjusting the reasonable drilling spacing, so that all drilling holes are evenly distributed, allowing the fungi to absorb nutrients evenly throughout the log and reducing the waste of nutrients in the log; the first and second connecting rods are installed on the drill bit mounting bracket 1 in an "X" shape. The first and second connecting rods are of equal length, and their length is the maximum distance between two adjacent drill bit mounting brackets 1. Therefore, the length of the first and second connecting rods is set according to the requirements. The first and second connecting rods are paired up, and preferably the number is equal to the number of drill bit mounting brackets 1.

[0057] In a more preferred embodiment, a telescopic device is further included, the two ends of which are fixedly connected to the two drill bit mounting frames 1 that are furthest apart.

[0058] Since all drill bit mounting brackets are connected by a linkage mechanism, the spacing can be adjusted synchronously. Therefore, the drilling spacing can be adjusted simply by adjusting the spacing between any two drill bit mounting brackets using the telescopic device. However, due to the characteristics of this diamond-shaped linkage mechanism, when there are multiple drill bit mounting brackets, the force required to adjust the spacing between two drill bit mounting brackets that are closer together is greater. Therefore, the drilling spacing can be adjusted by adjusting the distance between the two drill bit mounting brackets that are furthest apart, saving the force required for adjustment and making operation easier. The telescopic device can be a cylinder, a ball screw structure, or a gear and rack structure, all of which can be driven by a motor. The ball screw structure and the gear and rack structure can also be adjusted manually, making it convenient for users to adjust the drilling spacing.

[0059] In a more preferred embodiment, a measuring ruler is further included for measuring the distance between two adjacent drill bit mounting frames 1. One end of the measuring ruler is fixedly connected to one of the drill bit mounting frames 1, and the other end contacts the adjacent drill bit mounting frame 1. The length of the measuring ruler is greater than or equal to the maximum distance between two adjacent drill bit mounting frames 1.

[0060] In a more preferred embodiment, the single-row multi-hole log drilling component of this solution is installed on a single-row multi-hole log drilling machine. The single-row multi-hole log drilling machine includes an operating frame, a lifting operating component, a log fixing device, and a positioning device. The lifting operating component is installed on the operating frame, and the drill bit mounting frame 1 is installed on the lifting platform of the lifting operating component. The log fixing device and the positioning device are installed on the operating frame below the drill bit module 2. The lifting operating component can be electrically controlled, manually controlled, or both electrically and manually controlled for easy operation. It is used to control the up and down movement of the drill bit mounting frame 1. The lifting operating component includes a lifting platform and a motor or handle for driving the lifting platform to move up and down. The lifting platform is provided with a guide rail, and the drill bit mounting frame 1 is installed on the guide rail to facilitate the adjustment of the spacing between the drill bit mounting frames 1.

[0061] Example 4

[0062] Based on any of the above embodiments, a method for drilling holes using a single-row multi-hole log drilling assembly is also included:

[0063] S1. Fix the logs to the bottom of the drill bit module, and replace the drill bit module with one of the appropriate size after confirming the target of the log cultivation.

[0064] S2. Confirm whether there are defective areas in the drilling area on the log. If no, proceed to S3. If yes, adjust the sliding module to make the drill bit module avoid the defective area, and then proceed to S3.

[0065] S3. Control the drill bit mounting bracket to move the drill bit module downwards and drill a hole in the log;

[0066] S4. After rotating the log segment by a certain angle or replacing it with a new log segment, return to step S1.

[0067] In this case, it is preferable that the two rows of drill holes are arranged alternately. Therefore, after the log is rotated at a certain angle in step S4, the log or the drill bit module can be moved to make the new drill hole parallel to the previous row but staggered.

[0068] In a more preferred embodiment, the specific operational steps after a defective area exists on the log are as follows:

[0069] S201. Remove the connecting rod corresponding to the defective part, operate the handle on one side of the defective part, and perform the lateral unlocking operation, axial translation operation and embedding operation in sequence.

[0070] Since the limiting groove has a "7"-shaped structure, the lateral unlocking operation includes axial movement of the limiting block, causing it to translate within the "7"-shaped limiting groove; downward movement of the limiting block, moving it out of the limiting groove; axial translation operation involves axially translating the drill bit module on one side of the defect area, moving the limiting block below another limiting groove; the embedding operation is the opposite of the unlocking operation, including upward movement of the limiting block, moving it into the limiting groove; and axial movement of the limiting block, embedding it into the limiting groove; all of the above operations are achieved through the operating handle.

[0071] In a more preferred embodiment, if multiple defective locations exist, the movement distances of the drill bit modules are superimposed. For example, if there are two defects on the log section to be drilled next, the log section is divided into sections 1 (hole 1), 2 (defect 1), 2 (defect 2), and 3 (hole 3) by the defects. Keeping section 1 stationary, the drill bit module above defect 1 needs to move a distance 'a' to avoid section 1, and the drill bit module above defect 2 needs to move a distance 'b' to avoid section 2. Specifically, the connecting rod corresponding to the drill bit module above defect 1 is removed, and the drill bit module above defect 1 and away from section 1 is moved a distance 'a' away from section 1. Then, the specific value of distance 'b' is confirmed, and the connecting rod corresponding to the drill bit module above defect 2 is removed. The drill bit module above defect 2 and away from section 2 is moved a distance 'b' away from section 2. Preferably, after the drill bit modules have moved, the removed connecting rods can be reinstalled in their corresponding positions to connect all the drill bit modules, increasing the overall strength of the device and the synchronization of drilling.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0073] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
