Description

Technical Field

[0001] The invention relates to the field of mechanical equipment, in particular to a single-row multi-drilling wood segment punching assembly. Background Art

[0002] Log cultivation is an agricultural technology that uses wood as a culture medium. It is mainly used for the cultivation of edible and medicinal fungi such as Ganoderma lucidum, shiitake mushrooms, and black fungus. It usually uses logs of about 1m in length for cultivation. Holes are punched on the outer surface of the logs and inoculated into the holes. Fungi grow by decomposing the logs. During the growth process, since natural matrix is ​​used, no pesticides or fertilizers are required. It is a pure natural and pollution-free green food.

[0003] The planting process of log cultivation includes drilling, inoculation, fungus and other processes, among which the most labor-intensive process is log drilling. At present, in order to save manpower and speed up the drilling efficiency, equipment capable of single-row multi-drill drilling is usually used for drilling. However, due to the diversity of log materials, including different diameters, different curvatures, protrusions and depressions in the shape, and even hardening on the logs, the drilling holes do not meet the needs of log cultivation, and discarding the entire log is relatively wasteful. Therefore, it is necessary to avoid drilling in sections of the log that do not meet the requirements. The drill bit spacing of the existing single-row multi-drill drilling device is fixed, and it can only be achieved by multiple drilling, which is time-consuming and cumbersome to operate. Summary of the invention

[0004] The invention provides a single-row multi-drill wood segment punching assembly to solve the problem that the existing single-row multi-drill wood segment punching device cannot avoid the wood segment sections that do not meet the requirements in one punching operation, and the operation is cumbersome and time-consuming.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] A single-row multi-drill wood drilling assembly comprises a drill mounting frame and a drill module. The drill mounting frame comprises a plurality of vertically mounted frames, a slide rail mounted at the lower end of the frames and a slide module. The drill module is mounted at the lower end of the slide module.

[0007] The present invention arranges a slide rail and a sliding module at the lower end of the drill mounting frame to individually adjust the drill modules, thereby achieving the purpose of adjusting the spacing between some drill modules, so that the drill modules can avoid the wood sections that do not meet the requirements before the drilling operation, avoiding multiple drilling operations and reducing the time of the drilling operation.

[0008] Furthermore, the sliding module includes a sliding block embedded in the sliding rail, a guide rod fixedly connected to the lower end of the sliding block, and a drill base sleeved on the guide rod. The distance between the drill base and the sliding block is increased by pulling the drill base, thereby facilitating the movement of the sliding block.

[0009] Furthermore, a plurality of "7"-shaped limiting grooves are provided on the side wall of the slide rail, and a limiting block is provided on the side wall of the drill base, and the limiting block matches the limiting groove.

[0010] Since the drill module needs to be pressed down and lifted when drilling, the drill base will be pulled up, causing the drill module to deviate and affecting the drilling spacing. By setting a "7"-shaped limit groove, the limit block on the drill base is embedded into the limit groove to prevent the drill base from being pulled up when the drill module is pressed down and lifted, and it will not affect the operation of quickly adjusting the position of the drill base.

[0011] Furthermore, a tension elastic member is provided between the slide block and the drill base.

[0012] Through the rebound characteristics of the tension elastic part, the slide rail and the sliding module are locked. The position of the slide block can be adjusted by simply pulling up the drill base, and the pulling up of the drill base is cancelled. The rebounding tension elastic part can clamp the drill base on the slide rail. The operation is simple and quick, which improves the efficiency of adjusting the drilling spacing.

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

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

[0015] When a certain part in the middle of a log is not suitable for drilling, all the holes on one side of it need to be translated toward this side by a certain distance, so the corresponding drill bases need to be unlocked (the limit block moves out of the limit groove), translated and embedded (the limit block embeds into the limit groove) operations. It is time-consuming to operate multiple drill bases in sequence, which reduces work efficiency. Therefore, all cross bars are connected together through connecting rods 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 operate the cross bar twice to complete the adjustment of the drill base, which greatly reduces the operation time.

[0016] If there are multiple defective parts, the moving distances of the drill modules are superimposed on each other. There are two defects on the part of the log to be drilled next time. The defects are used as divisions to divide the log into hole 1, defect 1 hole 2, defect 2 and hole 3 sections in turn. The hole 1 section is kept stationary. The drill module above defect 1 needs to move a distance to avoid the defect 1 section, and the drill module above defect 2 needs to move b distance to avoid the defect 2 section. The specific operation is to remove the connecting rod corresponding to the drill module above defect 1, operate the drill module above defect 1 and away from the hole 1 section, and move a distance in the direction away from the hole 1 section. Then, confirm the specific value of the b distance, remove the connecting rod corresponding to the drill module above defect 2, operate the drill module above defect 2 and away from the hole 2 section, and move b distance in the direction away from the hole 2 section to ensure that the drill module avoids all defects and that the drilled holes meet the requirements for log cultivation. After the drill module is moved, the removed connecting rod can be installed again to the corresponding position to connect all the drill modules to increase the overall strength of the device and the synchronization of drilling.

[0017] Furthermore, the connecting rod is an arc tube that is sleeved on the cross bar from top to bottom, and both ends and the lower end of the connecting rod are set to be openings.

[0018] Due to the change in the spacing between the drill bit bases, the spacing between the cross bars also changes. By sleeved the arc tube onto two adjacent cross bars from above, the problem of the connecting rod being insufficiently long due to the change in the spacing between the cross bars can be avoided. At the same time, the operation of sleeved arc tube is simpler.

[0019] Furthermore, a first pin hole is provided at both ends of the connecting rod, and a plurality of second pin holes are provided at both ends of the cross bar. The first pin hole and the second pin hole are fixed by a pin, and the first pin hole and the second pin hole are both opened horizontally and perpendicular to the axis of the cross bar.

[0020] When operating the drill base to translate, it is necessary to operate the cross bar to perform an axial movement (the limit block translates in the "7"-shaped limit groove), press down (the limit block moves out of the limit groove), and a secondary axial movement (adjusting the position of the drill base to the left or right) in sequence. Therefore, it is necessary to limit the connecting rod and the cross bar in the vertical direction and axial direction. Therefore, it is chosen to achieve this by opening a pin hole horizontally and perpendicular to the axis of the cross bar.

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

[0022] Since the frame of the drill mounting frame is vertically arranged and the slide rail is horizontally arranged, when the drill base is located at both ends of the slide rail, during the drilling operation, the reaction force of the drill base on the slide rail is too large, which can easily damage the slide rail. The slide rail is reinforced by reinforcing ribs to enhance its structural strength.

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

[0024] (1) The present invention arranges a slide rail and a sliding module at the lower end of the drill mounting frame to adjust the drill modules individually, thereby achieving the purpose of adjusting the spacing between some drill modules, so that the drill modules can avoid the wood sections that do not meet the requirements before the drilling operation, thereby avoiding multiple drilling operations and reducing the time of the drilling operation;

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

[0026] (3) The slide rail and the sliding module are locked by the rebound characteristics of the tension elastic member. The position of the slide block can be adjusted by simply pulling up the drill base, and the pull-up of the drill base is canceled. The rebound tension elastic member can clamp the drill base on the slide rail, which is simple and quick to operate and improves the efficiency of adjusting the drilling spacing.

[0027] (4) All cross bars are connected together by connecting rods to achieve synchronous operation, saving operation time. At the same time, only the connecting rod corresponding to the part of the log that is not suitable for drilling needs to be removed, and the adjustment of the drill base can be completed by operating the cross bars twice, which greatly reduces the operation time.

[0028] (5) By putting the arc tube on two adjacent cross bars from above, the problem of the connecting rod being not long enough due to the change in the spacing between the cross bars can be avoided. At the same time, the operation of putting on the arc tube is simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Among them, the slide rail 102 is a closed slide rail with both ends closed to prevent the slider 301 from derailing. At the same time, since the opening of the slide rail 102 is set downward, it is preferred to set the opening width of the slide rail 102 to be smaller than the width of the slider 301, so that the slider 301 is restricted to slide inside it, and the guide rod 302 extends downward from the opening below the slide rail 102; similarly, in order to prevent the drill base 303 from detaching from the guide rod 302, the end of the guide rod 302 and the opening of the drill base 303 are preferably provided with a limiting structure, and the number of frames 101 is determined according to the number of holes required for drilling in the wood segment, and preferably the number is greater than or equal to the number of holes required for drilling in a section of wood segment, so as to achieve a single row of holes in the wood segment in a single operation, avoiding secondary drilling in the same row, and the drill module 2 is detachably mounted on the lower end of the drill mounting frame 1 for easy replacement.

[0046] Example 2

[0047] On the basis of Example 1, Figure 1-Figure 6 As shown, a handle is provided on the side wall of the drill base 303; the handle includes a longitudinal rod 501 fixedly connected to the side wall of the drill base 303, a cross rod 502 fixedly installed at the end of the longitudinal rod 501 and a connecting rod 503 sleeved between two adjacent cross rods 502.

[0048] Among them, one end of the longitudinal rod 501 is preferably fixedly installed on the center line of the side wall of the drill base 303 so that the drill base 303 is evenly stressed, and the other end is fixedly connected to the middle of the cross rod 502. When the drill base 303 is not operated, the axes of all the cross rods 502 are collinear; the number of connecting rods 503 is preferably one less than the number of cross rods 502, and a 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, and the connection method is to limit the cross rods 502 and the connecting rods 503 in the vertical direction and the axial direction.

[0049] In a more preferred embodiment, the connecting rod 503 is an arc tube that is sleeved on the cross bar 502 from top to bottom, and both ends and the lower end of the connecting rod 503 are set to be open.

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

[0051] In a more preferred embodiment, first pin holes 504 are provided at both ends of the connecting rod 503, and a plurality of second pin holes 505 are provided at both ends of the cross bar 502. The first pin holes 504 and the second pin holes 505 are fixed by means of latches.

[0052] Among them, the relative positions of the first pin hole 504 and the second pin hole 505 are the same, that is, when the connecting rod 503 is sleeved on the cross bar 502, the first pin hole 504 and the second pin hole 505 are located at the same height, which is convenient for the insertion of the pin, and 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 cross bar 502 are symmetrically distributed, and the second pin holes 505 at the same end are evenly spaced, and the number of the second pin holes 505 is determined according to demand.

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

[0054] Example 3

[0055] On the basis of Example 2, it also includes a plurality of parallel first connecting rods and a plurality of parallel second connecting rods installed on the drill bit mounting frame 1, the first connecting rod and the second connecting rod are of equal length, the middle part of the first connecting rod and the middle part of the second connecting rod are rotatably connected, the rotation axes of the first connecting rod and the second connecting rod are fixedly connected to the drill bit mounting frame, the two ends of the first connecting rod are respectively rotatably connected to the ends of two adjacent second connecting rods, and the two ends of the second connecting rod are respectively rotatably connected to the ends of two adjacent first connecting rods.

[0056] Among them, the existing devices all have fixed spacing, and the drilling spacing required for cultivating different fungi species is different. For example, the drilling spacing for cultivating shiitake mushrooms on logs is 10 cm, and the drilling spacing for cultivating white fungus on logs is 8 cm. Different hole spacings require the replacement of equipment with different drilling spacings, which increases the equipment cost. Therefore, a diamond-shaped connecting rod mechanism is formed by a plurality of first connecting rods and second connecting rods, so that all drill mounting frames move synchronously. At the same time, the first connecting rod and the second connecting rod of equal length also make the spacing between the drill mounting frames change synchronously and by the same amount, so as to achieve the purpose of equal spacing throughout the process, which not only solves the problem of long operation time when manually adjusting the spacing separately, It can also improve the accuracy of equal spacing; at the same time, some smaller defective sections can be avoided by adjusting the reasonable drilling spacing when all the holes are equally spaced, so that the holes are evenly distributed, so that the bacteria can evenly absorb the nutrients in the whole log, reducing the waste of nutrients in the log; the first connecting rod and the second connecting rod are installed on the drill mounting frame 1 in an "X" shape, the first connecting rod and the second connecting rod are of equal length, and their lengths are the maximum spacing between two adjacent drill mounting frames 1. Therefore, the lengths of the first connecting rod and the second connecting rod are set according to needs, and the first connecting rod and the second connecting rod are grouped in pairs, and preferably equal to the number of drill mounting frames 1.

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

[0058] Among them, since all the drill mounting frames are connected by a connecting rod mechanism, synchronous adjustment of the spacing is achieved. Therefore, the spacing of the drill holes can be adjusted by adjusting the spacing between any two drill mounting frames through the telescopic device. However, due to the characteristics of this diamond connecting rod mechanism, when there are multiple drill mounting frames, the force required to adjust the spacing between two drill mounting frames that are closer to each other is greater. Therefore, the drilling spacing is adjusted by adjusting the distance between the two drill mounting frames that are farthest apart, which saves the force required for adjustment and facilitates operation. The telescopic device can be a cylinder, a ball screw structure, or a gear rack structure, etc., all of which can be driven by a motor. The ball screw structure and the gear rack structure can also be adjusted manually, which is convenient for users to adjust the drilling spacing.

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

[0060] In a more preferred embodiment, the single-row multi-hole wood segment punching assembly in the present scheme is installed on a single-row multi-hole wood segment punching machine, which includes an operating frame, a lifting operation assembly, a wood segment fixing device and a positioning device, wherein the lifting operation assembly is installed on the operating frame, the drill bit mounting frame 1 is installed on the lifting platform of the lifting operation assembly, and the wood segment fixing device and the positioning device are installed on the operating frame below the drill bit module 2. The lifting operation assembly can be electrically controlled, manually controlled, or both electrically controlled and manually controlled, which is easy to operate and is used to control the up and down movement of the drill bit mounting frame 1. The lifting operation assembly includes a lifting platform and a motor or handle for driving the lifting platform to lift. 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, the method further includes punching holes using a single-row multi-hole wood punching assembly:

[0063] S1. Fix the log under the drill module, confirm the target of log cultivation and replace the drill module with the corresponding size;

[0064] S2, confirm whether there is a defective area in the drilling area of ​​the log, if not, execute S3, if yes, adjust the sliding module so that the drill module avoids the defective area, and then execute S3;

[0065] S3, controlling the drill mounting frame to move the drill module downward and drill a hole in the log;

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

[0067] Preferably, the two rows of drill holes are arranged in a staggered manner. Therefore, after the wood segment is rotated by a certain angle in step S4, the wood segment or the drill module can be translated to make the new drill holes parallel to the previous row but offset from each other.

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

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

[0070] Among them, since the limiting groove is a "7"-shaped structure, the lateral unlocking operation includes axial movement of the limiting block, so that the limiting block translates in the "7"-shaped limiting groove; the limiting block moves downward to move the limiting block out of the limiting groove; the axial translation operation is to control the axial translation of the drill module on one side of the defective part to move the limiting block to the bottom of another limiting groove; the embedding operation is the opposite of the unlocking operation, including moving the limiting block upward to move the limiting block into the limiting groove; the limiting block moves axially to embed the limiting block into the limiting groove; the above operations are all achieved by operating the handle.

[0071] In a more preferred embodiment, if there are multiple defective parts, the moving distances of the drill modules are superimposed on each other. For example, there are two defects on the part of the log to be drilled next time. The defects are used as partitions to divide the log into hole 1, defect 1 hole 2, defect 2 and hole 3 sections in turn. The hole 1 section is kept stationary. The drill module above defect 1 needs to move a distance to avoid the defect 1 section, and the drill module above defect 2 needs to move b distance to avoid the defect 2 section. The specific operation is to remove the connecting rod corresponding to the drill module above defect 1, operate the drill module above defect 1 and away from the hole 1 section, and move a distance in the direction away from the hole 1 section. Then, confirm the specific value of the distance b, remove the connecting rod corresponding to the drill module above defect 2, operate the drill module above defect 2 and away from the hole 2 section, and move b distance in the direction away from the hole 2 section. Preferably, after the drill module is moved, the removed connecting rod can be installed again to the corresponding position to connect all the drill modules to increase the overall strength of the device and the synchronization of drilling.

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.

[0073] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
