Description

Technical Field

[0001] The present invention relates to the field of mechanical equipment, and specifically, to a single-row multi-drill section wood punching machine. Background Art

[0002] Section wood cultivation is an agricultural technology that uses wood as a culture medium, mainly for the cultivation of edible and medicinal fungi such as Ganoderma lucidum, Lentinula edodes, and Auricularia auricula; it usually uses section wood about 1m long for cultivation, punches holes on the outer surface of the section wood, inoculates in the holes, and the fungi grow by decomposing the section wood. During the growth process, due to the use of natural substrates, no pesticides and fertilizers are required during the growth process, and it is a pure natural and pollution-free green food.

[0003] During the planting process of section wood cultivation, it includes multiple processes such as punching, inoculating, and spawn running. Among them, the most laborious link is section wood punching, and there are certain requirements for the aperture, spacing, row spacing, and depth of the punching; at present, in order to save labor and improve the punching efficiency, equipment capable of performing single-row multi-drill punching operations is usually used for punching. However, for section wood of different cultivated strains, there are certain differences in the aperture, spacing, row spacing, and depth that need to be punched. The existing devices can change the aperture by replacing the drill bit, and the row spacing and depth can be achieved through operations. However, the existing devices fix the spacing. Different drilling spacings are required for cultivating different strains of fungi. For example, the drilling spacing for section wood Lentinula edodes cultivation is 10 cm, and the drilling spacing for section wood Tremella fuciformis cultivation is 8 cm, etc. Different hole spacings require replacing devices with different punching spacings, increasing the equipment cost. At the same time, the punching spacing cannot be flexibly adjusted, and the equipment adaptability is not strong. Summary of the Invention

[0004] The present invention provides a single-row multi-drill section wood punching machine to solve the problem that the existing section wood punching equipment cannot flexibly adjust the punching spacing.

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

[0006] A single-row multi-drill section wood punching machine includes an operation frame, a drilling component installed on the operation frame, and a lifting operation component for controlling the lifting of the drilling component. The drilling component includes a plurality of parallel drill bit mounting frames, a drill bit module installed at the lower end of the drill bit mounting frame, and a spacing adjustment component for adjusting the spacing between the drill bit mounting frames.

[0007] The present invention adjusts the spacing between the drill bit mounting frames through the spacing adjustment component, thereby adjusting the spacing between the drill bit modules, and then operates the lifting operation component to move the drill bit module downward to the lower section wood for punching, realizing flexible adjustment of the punching spacing with simple operation.

[0008] Furthermore, the drilling assembly further includes a plurality of guide rails horizontally arranged on the operation frame, and the drill bit mounting frame is mounted on the guide rails.

[0009] By adjusting the spacing between the drill bit mounting frames through the horizontal guide rails, the purpose of adjusting the drilling spacing is achieved.

[0010] Furthermore, the spacing adjustment assembly includes a plurality of first connecting rods arranged in parallel and a plurality of second connecting rods arranged in parallel. The first connecting rods and the second connecting rods are of equal length. The middle parts of the first connecting rods and 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 rod are respectively rotatably connected to the ends of two adjacent second connecting rods. The two ends of the second connecting rod are respectively rotatably connected to the ends of two adjacent first connecting rods.

[0011] By forming a rhombic connecting rod mechanism with a plurality of first connecting rods and second connecting rods, all the drill bit mounting frames move synchronously. At the same time, the equal-length first connecting rods and second connecting rods also make the spacing between the drill bit mounting frames change synchronously and equally, achieving the purpose of equal spacing throughout the process. This not only solves the problem of long operation time when manually adjusting the spacing individually but also improves the accuracy of equal spacing.

[0012] Furthermore, the spacing adjustment assembly further includes a measuring scale for measuring the spacing between two adjacent drill bit mounting frames. One end of the measuring scale is fixedly connected to the drill bit mounting frame, and the other end is in contact with the adjacent drill bit mounting frame.

[0013] By observing the measuring scale, the spacing between two adjacent drill bit mounting frames can be accurately adjusted so that the drilled holes meet the requirements of log cultivation.

[0014] Furthermore, the spacing adjustment assembly further includes a telescopic device, and the two ends of the telescopic device are respectively fixedly connected to the two farthest drill bit mounting frames.

[0015] Since all the drill bit mounting frames are connected by a connecting rod mechanism to achieve synchronous adjustment of the spacing, only by adjusting the spacing between any two drill bit mounting frames through the telescopic device can the drilling spacing be adjusted. However, due to the characteristics of this rhombic connecting rod mechanism, when there are multiple drill bit mounting frames, the greater the force required to adjust the spacing between the two closer drill bit mounting frames. Therefore, by adjusting the distance between the two farthest drill bit mounting frames to adjust the drilling spacing, the force required for adjustment is saved and the operation is facilitated.

[0016] Furthermore, a slide rail and a sliding module are provided at the lower end of the drill bit mounting bracket. The sliding module includes a slider slidably embedded in 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. A tension elastic member is connected between the slider and the drill bit base.

[0017] Due to the diversity of the log wood, including different diameters, different curvatures, protrusions and depressions on the appearance, and even hardening on the log, the drilled holes do not meet the requirements of log cultivation. Discarding the whole log is relatively wasteful. Therefore, by using the slide rail and the sliding module, the size of a certain spacing can be adjusted individually to avoid the non-conforming log section and prevent waste of the log. At the same time, through the resilience of the tension elastic member, the slide rail and the sliding module can be locked. Just by lifting the drill bit base, the orientation of the slider can be adjusted. And when the lifting of the drill bit base is cancelled, the resilient tension elastic member can clamp the drill bit base on the slide rail. The operation is simple and fast, improving the efficiency of adjusting the drilling spacing.

[0018] Furthermore, a number of "7"-shaped limiting grooves are formed on the side wall of the slide rail, and a limiting block is provided on the side wall of the drill bit base, and the limiting block is matched with the limiting groove.

[0019] When drilling, since it is necessary to press down and lift the drill bit module, the drill bit base may be lifted, resulting in the deviation of the drill bit module and affecting the drilling spacing. By providing the "7"-shaped limiting groove and inserting the limiting block on the drill bit base into the limiting groove, the situation of lifting the drill bit base when pressing down and lifting the drill bit module can be prevented, and it does not affect the operation of quickly adjusting the position of the drill bit base.

[0020] Furthermore, reinforcing ribs are provided between the two ends of the slide rail and the drill bit mounting bracket.

[0021] Since the drill bit mounting bracket is vertically arranged and the slide rail is horizontally arranged, when the drill bit base is located at both ends of the slide rail during drilling operation, the reaction force of the drill bit base on the slide rail is too large, which is likely to damage the slide rail. The slide rail is reinforced by the reinforcing ribs to enhance its structural strength.

[0022] Furthermore, a handle is provided on the side wall of the drill bit base. By operating the handle, the up and down movement of the drill bit base can be realized, which is more convenient and labor-saving.

[0023] Furthermore, the handle includes a longitudinal rod connected to the side wall of the drill bit base, a cross rod fixedly installed at the end of the longitudinal rod, and a connecting rod sleeved between two adjacent cross rods.

[0024] When a certain part in the middle of the log is not suitable for drilling, all the drill holes on one side need to be translated a certain distance towards this side. Therefore, the corresponding drill bit bases all need to perform unlocking (the limiting block moves out of the limiting groove), translation, and embedding (the limiting block embeds into the limiting groove) operations. Sequentially operating multiple drill bit bases is time-consuming and reduces work efficiency. Therefore, all the crossbars are connected together through connecting rods to achieve synchronous operation and save 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 operating the crossbar twice can complete the adjustment of the drill bit base, greatly reducing the operation time.

[0025] If there are multiple defective parts, the moving distances of the drill bit modules are superimposed on each other. There are two defects on the part of the log for the next drilling. Divided by the defects, the log is sequentially divided into hole 1, defective part 1, hole 2, defective part 2, and hole 3 sections. Keeping the hole 1 section stationary, the drill bit module above the defective part 1 needs to move a distance of a to avoid the defective part 1 section, and the drill bit module above the defective part 2 needs to move a distance of b to avoid the defective part 2 section. The specific operation is as follows: remove the connecting rod corresponding to the drill bit module above the defective part 1, operate the drill bit module above the defective part 1 and in the direction away from the hole 1 section, and move a distance of a 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 bit module above the defective part 2, operate the drill bit module above the defective part 2 and in the direction away from the hole 2 section, and move a distance of b in the direction away from the hole 2 section to ensure that the drill bit modules avoid all the defects and make the drill holes meet the requirements of log cultivation; after the drill bit modules have moved, the removed connecting rod can be reinstalled at the corresponding position to connect all the drill bit modules, increasing the overall strength of the device and the synchronism of drilling.

[0026] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:

[0027] (1) The present invention adjusts the spacing between the drill bit mounting brackets through the spacing adjustment component, thereby adjusting the spacing between the drill bit modules, and then operates the lifting operation component to move the drill bit modules downward to the lower log for drilling, realizing flexible adjustment of the drilling spacing with simple operation;

[0028] (2) A rhombus-shaped connecting rod mechanism is formed by several first connecting rods and second connecting rods, enabling all the drill bit mounting brackets to move synchronously. At the same time, the equal-length first connecting rods and second connecting rods also make the spacing between the drill bit mounting brackets change synchronously and equally, achieving the purpose of equal spacing throughout the process. It not only solves the problem of long operation time when manually adjusting the spacing individually but also can improve the accuracy of equal spacing;

[0029] (3) By virtue of the resilience characteristics of the tension elastic member, simply lifting the drill base can adjust the orientation of the slider, and when the lifting of the drill base is cancelled, the resilient tension elastic member can clamp the drill base tightly on the slide rail, with simple and quick operation, improving the efficiency of adjusting the drilling spacing;

[0030] (4) By providing a "7"-shaped limiting groove and inserting the limiting block on the drill base into the limiting groove, it can prevent the drill base from being lifted when the drill module is pressed down or lifted, and it will not affect the operation of quickly adjusting the position of the drill base;

[0031] (5) By connecting all the cross bars together through the connecting rod to achieve synchronous operation, saving operation time. At the same time, only by removing the connecting rod corresponding to the part of the round wood that is not suitable for drilling, and operating the cross bar twice, the adjustment of the drill base can be completed, greatly reducing the operation time.

At the same time, since the opening of the slide rail 301 is arranged downward, preferably, the opening width of the slide rail 301 is set to be smaller than the width of the slider 302 to limit the slider 302 to slide inside it.

[0059] In a more preferred embodiment, the connecting rod 311 is an arc tube for sleeving on the cross bar 310 from top to bottom, and both ends and the lower end of the connecting rod 311 are provided with openings.

[0064] Embodiment 3

[0065] Based on any of the above embodiments, a method for drilling holes using a single-row multi-hole section wood drilling machine is further included:

[0066] S1. Fix the section wood under the drill bit module, confirm the target of section wood cultivation and the preset spacing of the required drilling holes, and replace the drill bit module with the corresponding size;

[0067] S2. Use the spacing adjustment component to adjust the spacing between the drill bit mounting brackets so that the spacing between two adjacent drill bit modules is equal to the preset spacing;

[0068] S3. Control the lifting operation component to move the drill bit module downward and drill holes in the section wood;

[0069] S4. After rotating the section wood by a certain angle or replacing the new section wood, return to step S1.

[0070] Among them, the operation of adjusting the spacing between the drill bit mounting brackets is specifically to control the telescopic device to extend or shorten, so as to adjust the spacing between the two farthest drill bit mounting brackets. Then, driven by the first connecting rod and the second connecting rod, all the drill bit mounting brackets between the two farthest drill bit mounting brackets will be driven, and the distance moved between the two farthest drill bit mounting brackets will be evenly distributed between every two adjacent drill bit mounting brackets by the link mechanism, achieving the purpose of equal spacing between any two adjacent drill bit mounting brackets;

[0071] Preferably, the two columns of drill holes are arranged staggeredly. After the section of wood rotates a certain angle in step S4, the section of wood can be translated or the drill bit module can be translated so that the new drill hole is parallel to the previous column but offset from it.

[0072] In a more preferred embodiment, the operation of the spacing adjustment assembly further includes:

[0073] S201. Observe and judge whether there are defects on the surface of the section of wood where drilling operation is about to be performed and whether the position of the drill bit module here needs to be adjusted. If not, execute S3. If so, remove the connecting rod corresponding to the defective part, operate the grip on one side of the defective part, and sequentially execute the lateral unlocking operation, the axial translation operation, and the embedding operation;

[0074] Among them, since the limit groove is a "7"-shaped structure, the lateral unlocking operation includes the axial movement of the limit block so that the limit block translates in the "7"-shaped limit groove; the limit block moves downward to move the limit block out of the limit groove; the axial translation operation is to control the drill bit module on one side of the defective part to perform axial translation to move the limit block below another limit groove; the embedding operation is opposite to the unlocking operation, including the upward movement of the limit block to move the limit block into the limit groove; the axial movement of the limit block to embed the limit block inside the limit groove; the above operations are all realized by operating the grip.

[0075] In a more preferred embodiment, if there are multiple defective parts, the moving distances of the drill bit modules are superimposed on each other. For example, there are two defects on the section of wood where the next hole is to be drilled. Divided by the defects, the section of wood is successively divided into hole 1, defect 1, hole 2, defect 2, and hole 3 sections. Keep the hole 1 section stationary. The drill bit module above defect 1 needs to move a distance to avoid the defect 1 section, and the drill bit module above defect 2 needs to move b distance to avoid the defect 2 section. Then the specific operation is to remove the connecting rod corresponding to the drill bit module above defect 1, operate the drill bit module above defect 1 and in the direction 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 b distance, remove the connecting rod corresponding to the drill bit module above defect 2, operate the drill bit module above defect 2 and in the direction away from the hole 2 section, and move b distance in the direction away from the hole 2 section. Preferably, the moved drill bit module matches the limit groove on its right side. In addition, after the drill bit module has moved, the removed connecting rod can be reinstalled at the corresponding position to connect all the drill bit modules, increasing the overall strength of the device and the synchronism of drilling.

Therefore, the appended claims are intended to be interpreted to include the preferred embodiments as well as all changes and modifications falling within the 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 equivalent technologies, the present invention is also intended to include these modifications and variations.
