Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural machinery, in particular to a segment wood drilling device and a control method. BACKGROUND

[0002] Segment wood cultivation is an important method of cultivating edible fungi. This method uses segment wood as the growth substrate for edible fungi, and through inoculation of edible fungus spores, it promotes the growth and development of mycelium under suitable environmental conditions, and ultimately forms a complete fruiting body. Segment wood contains rich nutrients such as lignin and cellulose, which provide the necessary energy and nutrient sources for edible fungi. At the same time, the hardness and stability of segment wood also provide a stable support environment for the growth of edible fungi. When using segment wood for cultivation, a series of holes need to be pre-processed on the segment wood to inoculate edible fungus spores. When drilling holes in segment wood, the depths of these holes need to be uniform so that the growth of edible fungi in each hole of the same segment wood is uniform. Different types of edible fungi have different requirements for the depth and distribution density of holes, which makes it necessary for growers, especially small-scale farmers, to choose manual drilling to drill holes that meet the requirements, which requires a long time and consumes a lot of labor. SUMMARY

[0003] The segment wood drilling device of the present application improves the problem of long working hours and labor consumption in the prior art for drilling holes in segment wood for cultivating edible fungi, which is beneficial to shorten the working hours and save labor.

[0007] wherein the first state is the state of the drilling mechanism when the drill bit is away from the fixing frame, and the second state is the state of the drilling mechanism when the drill bit is close to the fixing frame;

[0008] The first direction is the sliding direction of the first driving member relative to the fixed frame, and the second direction has an included angle with the first direction greater than 0° and less than 180°. When the segment wood drilling equipment is used, the segment wood is fixed on the fixed frame along the second direction, and the fixed frame is moved along the second direction to place the segment wood at different positions along the axial direction below the drill bit along the first direction. At this time, the drilling mechanism is started, the drill bit can drill holes in the segment wood in the second state of the drilling mechanism. Due to the blocking of the limiting piece, the drill bit cannot continue to penetrate after drilling into the segment wood to a certain depth, thereby achieving the purpose of controlling the drilling depth. By adjusting the position of the limiting piece along the axial direction of the drill bit, holes with different depths can be drilled. After the first hole is drilled on the surface of the segment wood, the drilling mechanism is switched to the first state, and the drill bit is away from the segment wood. At this time, moving the fixed frame along the second direction can move the processing position of the next hole on the surface of the segment wood to below the drill bit, and the hole spacing can be changed by adjusting the movement distance of the fixed frame. In addition, a separate measuring tool or a pre-marked fixed frame can be used to mark appropriate hole spacing to adapt to the needs of different types of edible fungi for cultivation on segment wood.

The diameters of the segment wood that needs to be drilled are quite different, and when drilling different diameter segment wood, the second driving member can be used to drive the sliding table to move along the first direction, thereby changing the position of the stroke limit of the drill bit at both ends along the first direction, so that the segment wood drilling equipment can have a stable effect when processing different diameter segment wood.

The arrangement of the first guide rail and the second guide rail enables the fixing frame to move along the first guide rail and the second guide rail, thereby expanding the moving range of the fixing frame and enabling the log drilling equipment to drill holes at any position on the log outer wall.

[0013] As an optional technical solution, the positioning sensor is arranged corresponding to the fixing frame along the second direction.

[0019] S40: according to the hole interval and the distance from the drill bit to the log along the first direction, the processing position of the next hole on the log surface is indicated by laser. The ratio of the hole interval to the distance from the drill bit to the log along the first direction is the sine value of the relative first direction angle of the laser, so that the angle that the laser should be deflected can be calculated, thereby the laser is deflected to determine the position of the next hole after the position of the first hole is determined, which is beneficial to the operator to make timely adjustment.

[0020] As an optional technical solution, the control method further comprises:

[0046] Embodiment one

[0047] The embodiment provides a segment wood punching equipment, which comprises a drilling mechanism 1 and a sliding platform 2. The drilling mechanism 1 has a first state and a second state, and the drilling mechanism 1 comprises a drill bit 11, a first driving piece 12 and a limiting sheet 13, the limiting sheet 13 is adjustably sleeved on the outer periphery of the drill rod of the drill bit 11 along a first direction Z, and the first driving piece 12 is connected to the drill bit 11. The first driving piece 12 is used for driving the drilling mechanism 1 to switch between the first state and the second state. The sliding platform 2 comprises a fixing frame 21, the fixing frame 21 is provided corresponding to the drill bit 11, and the fixing frame 21 is slidably arranged along a second direction X.

[0048] The first state is the state of the drilling mechanism 1 when the drill bit 11 is away from the fixing frame 21, and the second state is the state of the drilling mechanism 1 when the drill bit 11 is close to the fixing frame 21. The first direction Z is the sliding direction of the first driving piece 12 relative to the fixing frame 21, and the included angle between the second direction X and the direction is greater than 0° and less than 180°.

[0049] The segment wood drilling equipment of the present application uses the segment wood to be fixed on the fixed frame 21 along the second direction X, and the fixed frame 21 is moved along the second direction X to place the segment wood at different positions along the axial direction below the drill bit 11 along the first direction Z. At this time, the drilling mechanism 1 is started, and the drill bit 11 cannot continue to penetrate into the segment wood due to the blocking of the limiting piece 13, so as to achieve the purpose of controlling the drilling depth. By adjusting the position of the limiting piece 13 along the axial direction of the drill bit 11, holes with different depths can be drilled. After the first hole is drilled on the surface of the segment wood, the drilling mechanism 1 is switched to the first state, and the drill bit 11 is away from the segment wood. At this time, moving the fixed frame 21 along the second direction X can move the processing position of the next hole on the surface of the segment wood to below the drill bit 11, and the hole spacing can be changed by adjusting the moving distance of the fixed frame 21.

[0050] In addition, a separate measuring tool or a method of marking appropriate hole spacing in advance on the fixed frame 21 can also be used to adapt to the needs of different types of edible fungi for planting on segment wood.

[0051] For example, the first driving member 12 can be a pneumatic cylinder. Using a pneumatic cylinder as the first driving member 12 has the advantages of low cost, low maintenance difficulty, simple structure, and the like. For users, especially small-scale farmers, the burden is smaller. In addition, magnetic switches or other sensors can be arranged at both ends of the stroke of the first driving member 12, so as to facilitate the control terminal to control the first driving member 12 and improve the intelligent level of the segment wood drilling equipment, thereby further saving labor. In addition, the first driving member 12 can also be an electric motor or a hydraulic motor, and can also be used with various transmission devices such as a lead screw.

[0052] It should be noted that the fixed frame 21 can be directly driven by human power along the second direction X. In this way, the number of driving devices and transmission devices in the segment wood drilling equipment can be reduced, which is beneficial to reduce the cost and maintenance difficulty of the segment wood drilling equipment. Generally, small-scale farmers have limited ability to use and maintain agricultural machinery. The use of human power to drive the fixed frame 21 is beneficial to the use of farmers. In addition, the plane on which the sliding track of the fixed frame 21 is located can be arranged parallel to the ground. In this way, when the fixed frame 21 is driven by human power to slide, the operator does not need to overcome the gravity work, and the requirement for the strength and endurance of the operator is lower. In addition, when the segment wood to be drilled has a large volume and a heavy weight, an electric motor or the like can also be used to drive. The selection should be made according to the specific contradictions in practice.

[0053] Preferably, the first direction Z is perpendicular to the second direction X.

[0054] Embodiment two

[0055] On the basis of the first embodiment, the segment wood drilling device further comprises a rack 3 and a sliding table 31, one side of the sliding table 31 is slidingly connected to the rack 3 along the first direction Z, the drill bit 11 is slidingly connected to the other side of the sliding table 31 along the first direction Z, and the first driving member 12 is installed on the sliding table 31; the rack 3 comprises a second driving member 32, and the second driving member 32 is connected to the sliding table 31. The diameters of the segment woods to be drilled are quite different, and when drilling the segment woods with different diameters, the second driving member 32 can be used to drive the sliding table 31 to move along the first direction Z, so as to change the position of the stroke limit of the drill bit 11 at both ends along the first direction Z, thereby enabling the segment wood drilling device to have a relatively stable effect when processing segment woods with different diameters. For example, when processing a segment wood with a smaller diameter, the drill bit 11 is lowered to the limit, but the limiting piece 13 does not contact the surface of the segment wood, so that the depth of the hole processed will be less than the predetermined hole depth, which will affect the planting of edible fungi. At this time, the sliding table 31 is lowered to enable the drill bit 11 to further drill into the interior of the segment wood until the limiting piece 13 contacts the surface of the segment wood.

[0056] For example, the second driving member 32 can be a linear motor or a common motor cooperating with a screw rod and the like transmission mechanism, and the present embodiment is not limited thereto.

[0057] As an optional technical solution, the rack 3 further comprises a distance measuring sensor 5, the distance measuring sensor 5 is arranged on the drill bit 11, the distance measuring sensor 5 is signal connected to the second driving member 32, and the distance measuring sensor 5 is used to measure the distance between the drill bit 11 and the surface of the segment wood along the first direction Z. By obtaining the current position of the second driving member 32 and the distance between the drill bit 11 and the surface of the segment wood along the first direction Z, the distance measuring sensor 5 can calculate the diameter of the segment wood being processed, and then guide the second driving member 32 to drive the sliding table 31 to move a distance, which is beneficial to improve the automation degree of the segment wood drilling device and improve the work efficiency.

[0058] As an optional technical solution, a laser 4 is further included, the laser 4 is rotationally arranged on the drilling mechanism 1, the rotary plane of the laser 4 is parallel to the second direction X, the laser 4 is signal connected to the distance measuring sensor 5, and the laser 4 is arranged corresponding to the fixed frame 21. The light of the laser 4 can indicate the processing position of the hole on the surface of the segment wood, which is beneficial to intuitively reflect the processing process to the operator and facilitate the operator to make timely adjustments.

[0059] As an optional technical solution, the sliding platform 2 further comprises a base 22 and a first guide rail 23, the base 22 is provided with a second guide rail 24, the first guide rail 23 is arranged on the second guide rail 24 along a second direction X, and the fixing frame 21 is slidingly arranged on the first guide rail 23; wherein the extension direction of the second guide rail 24 has an included angle greater than 0° and less than 180° with the first direction Z and the second direction X. The arrangement of the first guide rail 23 and the second guide rail 24 enables the fixing frame 21 to move along the first guide rail 23 and the second guide rail 24, thereby expanding the moving range of the fixing frame 21 and enabling the log perforating device to perforate any position on the outer wall of the log. Preferably, the extension directions of the first guide rail 23 and the second guide rail 24 are perpendicular to each other.

[0060] As an optional technical solution, a positioning sensor 6 is further arranged corresponding to the fixing frame 21 along the second direction X. The positioning sensor 6 can obtain the displacement of the fixing frame 21 along the second direction X, thereby monitoring the interval of the perforation on the log. Exemplarily, the positioning sensor 6 can be an infrared three-wire positioner, or a laser ranging sensor 5 arranged at the end of the first guide rail 23, etc.

[0061] Optionally, a waste box 7 can be arranged below the sliding platform 2 to receive the wood chips generated by the perforation.

[0062] Optionally, a baffle 8 can be arranged on the outer periphery of the drill bit 11 to prevent the wood chips from splashing and affecting the operation during drilling.

[0063] Embodiment three

[0064] The embodiment provides a control method for controlling the log perforating device of the embodiment one, and provides a control terminal. The control terminal can be a PLC (programmable logic controller), a PAC (programmable automation controller), etc., which is not limited in the present application.

[0065] The control method further comprises the following steps:

[0066] S10: setting the hole interval and the hole depth to the control terminal;

[0067] S20: keeping the position of the fixing frame 21 fixed, controlling the drill bit 11 to switch to the second state by the control terminal, and drilling a first hole on the surface of the log; obtaining the position of the fixing frame 21 by the positioning sensor 6 and recording by the control terminal;

[0068] S30: switching the drill bit 11 to the first state by the control terminal, and measuring the distance from the drill bit 11 to the log along the first direction Z by the ranging sensor 5;

[0069] S40: According to the hole spacing and the distance of the drill bit 11 to the log along the first direction Z, the laser emitted by the laser 4 indicates the processing position of the next hole on the surface of the log. The ratio of the hole spacing to the distance of the drill bit 11 to the log along the first direction Z is the sine value of the angle of the laser relative to the first direction Z, so that the angle at which the laser should be deflected can be calculated, and after the position of the first hole is determined, the laser is deflected to determine the position of the next hole, which facilitates timely adjustment by the operator.

[0070] As an optional implementation, the control method further comprises:

[0071] S50: Move the fixing frame 21 along the second direction X, and the control terminal obtains the position information of the fixing frame 21 and calculates the remaining movement distance required for processing the next hole of the fixing frame 21 according to the hole spacing;

[0072] S60: According to the remaining movement distance and the distance of the drill bit 11 to the log along the first direction Z, the laser is deflected so that the laser always irradiates the processing position of the next hole on the surface of the log during the movement of the fixing frame 21;

[0073] S70: When the remaining movement distance is 0, the laser flashes to prompt the fixing frame 21 to stop moving.

[0074] Especially for the implementation in which the fixing frame 21 in the above is driven by manpower, the laser always irradiates the processing position of the next hole on the surface of the log during the movement of the fixing frame 21, and the operator only needs to observe the state of the light spot to determine whether the fixing frame 21 is moved to the position, which is relatively convenient and efficient.

[0075] As an optional implementation, the log hole drilling device further comprises a start switch, and the start switch is signal connected to the control terminal. When the on time of the start switch is less than 0.5 seconds, the drill bit 11 rotates and the hole drilling mechanism 1 drills a hole once. When the on time of the start switch is greater than or equal to 0.5 seconds, the drill bit 11 keeps rotating and the hole drilling mechanism 1 cycles between the first state and the second state until the start switch is turned off. The proficiency of the operator is different, and for the relatively inexperienced operator, the start switch can be pressed short (the on time is less than 0.5 seconds) each time to drill a hole, which improves the safety and quality of the operation. For the relatively skilled operator, the start switch can be pressed long (the on time is greater than or equal to 0.5 seconds), which improves the production efficiency. Exemplarily, the start switch can be a foot switch or a common button switch, etc.

[0076] As an optional implementation, the segment wood drilling device further comprises a frame 3 and a sliding table 31, one side of the sliding table 31 is slidingly connected to the frame 3 along the first direction Z, the drill bit 11 is slidingly connected to the other side of the sliding table 31 along the first direction Z, and the first driving member 12 is installed on the sliding table 31; the frame 3 comprises a second driving member 32, and the second driving member 32 is connected to the sliding table 31; the step S10 further comprises the following steps between the step S20 and the step S30:

[0077] S11: moving the drill bit 11 away from the fixed frame 21 along the first direction Z to a limit position;

[0078] S12: acquiring the distance between the drill bit 11 and the surface of the segment wood by the distance measuring sensor 5;

[0079] S13: moving the sliding table 31 until the distance between the drill bit 11 and the surface of the segment wood is the difference between the stroke of the drill bit 11 along the first direction Z and the hole depth.

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