Description

Technical Field

[0001] The present invention relates to the technical field of fungus production, specifically to a mushroom stick punching and inoculating device and a puncher based on the principle of a double crank slider. Background Technique

[0002] Fungi are one of the special products in China and have been exported for many years. The output of fungi in China reached more than 1 million tons in 1999, ranking first in the world. Fungi are also mushrooms consumed worldwide. Most of the fungi in China are sold as dried products, and there is also a certain amount of fresh products exported in recent years. In order to meet the market demand, people have developed methods for artificially cultivating fungi. The main method is to simulate the growth environment of fungi, make mushroom sticks with culture medium, plant mycelium on the mushroom sticks, place the mushroom sticks in the simulated environment to make the fungi grow, and pick the mushrooms from the mushroom sticks after the fungi grow. During the process of planting edible mushroom sticks, it is generally necessary to punch holes in the cultivated edible mushroom sticks for inoculating the mother species of the edible mushroom sticks or for ventilation. For the existing mushroom stick punching and inoculating device, generally after punching is completed by a machine, the corresponding mushroom material is pressed into the hole groove manually. This process has extremely low efficiency, and the manual pressing force is uneven, which is likely to cause the mushroom material to fall off. Summary of the Invention

[0014] Preferably, a material guiding frame is installed on the upper surface of the bottom plate through a fixing rod, and the material guiding frame is arranged in the middle of the support frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the first embodiment of the present invention based on the double crank-slider principle, since the sliding rate of the movable plate inside the slide rail is relatively small compared to the sliding rate of the movable strip on the movable plate, and the punching cylinder is arranged on the movable plate, the cross bar is arranged on the movable strip, and there is a distance difference between the push block where the guide rod is located and the insertion part of the punching cylinder. That is, when the punching cylinder moves and inserts into the mushroom stick to complete punching, subsequently, the guide rod drives the push block to push out the mushroom material inside the punching cylinder and press it inside the mushroom stick, realizing the automatic punching and inoculation process, improving the production efficiency. At the same time, due to the quick pressing of the guide rod driving the push block, the pressing force is ensured, further improving the inoculation quality.

[0017] 2. Through the ingenious design of the feeding mechanism and further setting of the structure, when the movable plate and the movable strip move back to their original positions, the channel where the second baffle is located can be opened, while the channel where the first baffle is located is closed. At this time, the bacterial material can be located above the first baffle, and the amount of material is determined by the distance between the second baffle and the first baffle. When punching and inoculating, at this time, the movable strip moves towards the end far away from the L-shaped connecting block. The L-shaped connecting block loses the extrusion effect of the backing plate and starts to reset under the elastic force of the first spring. At this time, the channel where the first baffle is located is opened, and the bottom of the bacterial material placement cylinder starts to drop materials. At the same time, the punching cylinder at the bottom also moves relatively, and the moving speed is less than the moving speed of the first baffle. Due to the relatively large caliber of the feeding port and the relative setting of the moving speed, the bacterial material can enter the inside of the punching cylinder. This process realizes automatic feeding, and at the same time, it can ensure that the amount of inoculated bacterial material is the same, further improving the inoculation efficiency and quality.

[0018] 3. Through the cooperation of the support mechanism and the feeding mechanism set in the present invention, when the fixed strip starts to return to its original position, in the initial state, after the punching cylinder pulls out the bacterial stick, the teeth at the end of the fixed strip mesh with the corresponding gear. At this time, the rotation direction of the gear can make the mounting plate rotate, so as to facilitate inoculation at the next position. Reciprocating in turn, since the punching cylinder is symmetrically arranged, when the mounting plate rotates by °, the circumferential inoculation of the bacterial stick can be completed, further improving its working efficiency and application range.

[0019] 4. In the present invention, the baffle rotates on the top of the mounting plate. At this time, the infrared emitter on the baffle is docked with the infrared receiver. The controller receives the signal and senses and controls the telescopic cylinder to contract. At this time, the bacterial stick after punching and inoculation can fall off and be sent out by the guide plate, realizing the automatic discharging process.

[0020] 5. Based on the second implementation mode of the double crank-slider principle, since the sliding rate of the movable plate inside the slide rail is relatively small compared to the sliding rate of the movable strip on the movable plate, and the length of the punching needle is less than the length of the limiting rod. When the movable plate drives the limiting rod to contact the outer wall of the bacterial stick at a relatively slow speed to fix it, then the movable strip drives the punching needle to quickly insert into the bacterial stick to complete punching. At the same time, due to the speed of the limiting rod and the action of the second spring, when the punching needle is pulled out, the limiting rod still fits with the outer wall of the bacterial stick to limit and fix it, thus greatly improving the stability of the insertion and extraction process of the punching needle. On the one hand, it can reduce the possibility of damage to the punching needle, and on the other hand, it improves the quality of the punching holes. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, it should not be construed as a limitation to the present invention. The embodiments of the present invention will be described in detail below with reference to the drawings. Embodiment

[0033] Reference Figures 1 to 7 , a mushroom stick punching and inoculation device based on the double crank-slider principle, comprising a workbench 1. Two groups of punching and inoculation mechanisms are arranged on the upper surface of the workbench 1. A support assembly for placing mushroom sticks is also arranged on the upper surface of the workbench 1, and the support assembly is located between the two groups of punching and inoculation mechanisms;

[0034] Each group of punching and inoculation mechanisms includes two side plates 3 fixed on the upper surface of the workbench 1. Slide rails 21 are respectively fixed on the opposite surfaces of the two side plates 3. An active plate 17 is slidably installed inside each slide rail 21. An active bar 18 is slidably installed in the upper part of the active plate 17 through an installation groove. A plurality of punching cylinders 22 are fixed between the two active plates 17 through installation parts. The punching cylinders 22 are used for punching mushroom sticks. A feeding mechanism for supplementing bacterial material into each punching cylinder 22 is arranged at the top of the side plate 3. A pressing mechanism is connected between the two active bars 18. The pressing mechanism is used for inoculating the bacterial material inside the punching cylinder 22 onto the mushroom stick. A first double crank-slider mechanism is installed on the side wall of the side plate 3. The first double crank-slider mechanism is used to drive the active plate 17 to slide inside the slide rail 21 and the active bar 18 to slide on the active plate 17.

[0035] The first implementation method applying the double crank-slider principle is applicable to the punching and inoculation process. A plurality of punching cylinders 22 are fixed between the two active plates 17 through installation parts. A pressing mechanism is connected between the two active bars 18. Based on the principle of the double crank-slider mechanism, the sliding rate of the active plate 17 inside the slide rail 21 is smaller than the sliding rate of the active bar 18 on the active plate 17. That is, when the punching cylinder 22 moves and inserts into the mushroom stick to complete punching, the subsequent pressing mechanism can then push out the bacterial material inside the punching cylinder 22 and press it inside the mushroom stick, realizing the automatic punching and inoculation process, improving the production efficiency. At the same time, due to the rapid pressing of the push block driven by the guide rod 24, the pressing force is ensured, further improving the inoculation quality.

[0036] Specifically, the first double crank-slider mechanism includes a first connecting rod 12, a third connecting rod 15, and a fourth connecting rod 16. The first connecting rod 12 is rotatably installed on the movable strip 18 through a pin shaft. The fourth connecting rod 16 is rotatably installed on the movable plate 17 through a pin shaft. The third connecting rod 15 is rotatably installed on the side wall of the side plate 3 through a pin shaft. A motor 2 is fixedly installed on the outer wall of the side plate 3. The output shaft of the motor 2 extends to the outer wall of the side plate 3 and is fixed with a rotating rod 14. One end of the rotating rod 14 is rotatably installed with a second connecting rod 13. One ends of the first connecting rod 12, the third connecting rod 15, and the fourth connecting rod 16 are rotatably connected to the second connecting rod 13 through a pin shaft. The connection between the third connecting rod 15 and the first connecting rod 12 is located at both ends of the second connecting rod 13, and the connection of the fourth connecting rod 16 is located in the middle of the second connecting rod 13.

[0037] Drive the corresponding motor 2 on the side plate 3 to work. The motor 2 can further drive the rotating rod 14 to rotate. With the connection effect of the second connecting rod 13 and the third connecting rod 15, when the rotating rod 14 drives the second connecting rod 13 to swing, on the one hand, the movable plate 17 can slide inside the slide rail 21. On the other hand, the movable strip 18 can slide relatively on the movable plate 17. Since the first connecting rod 12 and the fourth connecting rod 16 are at different connection positions of the second connecting rod 13, the sliding speed of the movable plate 17 inside the slide rail 21 is smaller than the sliding speed of the movable strip 18 on the movable plate 17.

[0038] Specifically, the pressing mechanism includes a cross bar 19. The cross bar 19 is fixedly installed between the two movable strips 18. A plurality of guide rods 24 are fixedly installed on the side wall of the movable strip 18. One end of each guide rod 24 away from the cross bar 19 extends into the corresponding punching cylinder 22 and is installed with a push block.

[0039] Since the punching cylinder 22 is arranged on the movable plate 17, the cross bar 19 is arranged on the movable strip 18, and there is a distance difference between the push block where the guide rod 24 is located and the insertion part of the punching cylinder 22. At the same time, since the moving speed of the movable plate 17 is less than that of the movable strip 18, that is, when the punching cylinder 22 moves and inserts into the mushroom stick to complete punching, the subsequent guide rod 24 drives the push block to push out the mushroom material inside the punching cylinder 22 and press it inside the mushroom stick.

[0040] Specifically, the feeding mechanism includes a mounting frame 35 which is fixedly installed on the tops of two side plates 3. A plurality of bacterial material placing cylinders 20 are installed on the mounting frame 35. Each punching cylinder 22 is provided with a feeding port 23 for the bacterial material to enter. Two through grooves 29 are formed in the bacterial material placing cylinder 20. A first baffle plate 28 and a second baffle plate 31 are respectively slidably installed inside the two through grooves 29. The second baffle plate 31 and the first baffle plate 28 are arranged in a staggered manner. A vertical bar 32 is fixedly connected to the rear sides of the second baffle plate 31 and the first baffle plate 28. An L-shaped connecting block 33 is fixedly installed in the middle of the vertical bar 32. A first spring 30 is connected between the L-shaped connecting block 33 and the side wall of the bacterial material placing cylinder 20.

[0041] After the punching and inoculation for one time are completed, the L-shaped connecting block 33 can move, which can drive the second baffle plate 31 and the first baffle plate 28 to slide inside the through groove 29. Due to the staggered arrangement of the second baffle plate 31 and the first baffle plate 28, when the movable plate 17 and the movable bar 18 move back to their original positions, the channel where the second baffle plate 31 is located can be opened, while the channel where the first baffle plate 28 is located is closed. At this time, the bacterial material can be located above the first baffle plate 28. The amount of the material is determined by the distance between the second baffle plate 31 and the first baffle plate 28. When punching and inoculating, if the movable bar 18 moves towards the end far from the L-shaped connecting block 33 at this time, the L-shaped connecting block 33 loses the extrusion effect of the backing plate 34 and starts to reset under the elastic force of the first spring 30. At this time, the channel where the first baffle plate 28 is located is opened, and the bacterial material at the bottom of the bacterial material placing cylinder 20 starts to fall. At the same time, the punching cylinder 22 at the bottom also moves relatively, and the moving speed is less than the moving speed of the first baffle plate 28. Due to the relatively large diameter of the feeding port 23 and the relative setting of the moving speeds, the bacterial material can enter the punching cylinder 22. In this process, automatic feeding is realized, and at the same time, the amount of the inoculated bacterial material can be ensured to be the same, further improving the inoculation efficiency and quality.

[0042] Specifically, connectors 27 are respectively fixedly installed at the front ends of the two movable bars 18. A backing plate 34 for pushing the L-shaped connecting block 33 to move is connected between the two connectors 27.

[0043] After the punching and inoculation for one time are completed, the movable plate 17 and the movable bar 18 start to reset. Through the connectors 27 connected to the movable bar 18, the connectors 27 can further drive the backing plate 34 to move, so as to make a plurality of L-shaped connecting blocks 33 move.

[0044] Specifically, the supporting assembly includes two supporting bars 7 fixed on the workbench 1. The upper parts of the two supporting bars 7 are respectively rotatably installed with mounting shafts through through holes. One end of each mounting shaft is fixedly installed with a mounting disc 9. Telescopic cylinders 36 for clamping the bacterial rods are respectively fixed on the opposite surfaces of the two mounting discs 9. And baffle plates 10 for supporting the bacterial rods are arranged on the two mounting discs 9.

[0045] Place the mushroom sticks to be punched and inoculated between the two mounting plates 9 and support them with the baffle 10. Then, drive the telescopic cylinder 36 so that the two telescopic cylinders 36 can clamp the two ends of the mushroom stick.

[0046] Specifically, a feeding mechanism for driving the intermittent rotation of the mushroom stick is connected to one of the support bars 7. The feeding mechanism includes a cross bar 4, which is slidably installed in the groove formed in the side plate 3, and one end of the cross bar 4 is fixed to the back of the movable plate 17. The other end of the cross bar 4 is connected to a fixed bar 45 through a mounting rod 5. The other end of one of the mounting shafts extends to the outer wall of the support bar 7 and is installed with a gear 6 through a one-way bearing 8. The front end of the fixed bar 45 is provided with teeth meshing with the gear 6.

[0047] When the movable plate 17 and the movable bar 18 reciprocate once, a punching and inoculation process can be completed. Through the connection between the cross bar 4 and the mounting rod 5, when the movable plate 17 reciprocates, the reciprocating movement of the fixed bar 45 can be realized. When the fixed bar 45 moves towards the end close to the gear 6, due to the one-way transmission of the one-way bearing 8, the gear 6 at this time will not drive the mounting plate 9 to rotate, and the mushroom stick remains stationary at this time, so that the punching and inoculation process can be realized. When the fixed bar 45 starts to return to its original position, in the initial state, after the punching cylinder 22 pulls out the mushroom stick, the teeth at the end of the fixed bar 45 mesh with the corresponding gear 6. At this time, the rotation direction of the gear 6 can cause the mounting plate 9 to rotate, thus facilitating the inoculation at the next position. In this way, due to the symmetric arrangement of the punching cylinders 22, when the mounting plate 9 rotates 180°, the circumferential inoculation of the mushroom stick can be completed.

[0048] Specifically, an opening groove is also formed in the middle of the workbench 1. The inner top of the workbench 1 is fixedly installed with a material guiding plate 11. The opening groove is arranged above the material guiding plate 11. The top of the side plate 3 is fixedly installed with a fixed bar 45. An infrared receiver 46 is arranged in the middle of the fixed bar 45. An infrared emitter is installed at the bottom of the baffle 10 directly below the infrared receiver 46.

[0049] When the circumferential inoculation of the mushroom stick is completed, at this time, the mounting plate 9 rotates 180°, so that the baffle 10 rotates to the top of the mounting plate 9. At this time, the infrared emitter on the baffle 10 is docked with the infrared receiver 46. The controller receives the signal and senses it and controls the telescopic cylinder 36 to contract. At this time, the punched and inoculated mushroom stick can fall off and be sent out by the material guiding plate 11. Embodiment

[0050] Reference Figures 8 to 10, A hole punch based on the double crank-slider principle, including a bottom plate 37, a support frame 38 is fixedly installed on the bottom plate 37, four mounting plates 40 are annularly arranged on the support frame 38, and a second double crank-slider mechanism is installed on each mounting plate 40. The second double crank-slider mechanism has the same structure as the first double crank-slider mechanism. A fixed block 41 is fixedly connected to the side wall of the movable plate 17 where the second double crank-slider mechanism is located. A limiting rod 42 is movably installed in the fixed block 41 through a through hole. A second spring 43 is connected to the outer wall of the limiting rod 42 between the end of the limiting rod 42 and the fixed block 41. A punching needle 44 is fixedly connected to the end of the movable bar 18 where the second double crank-slider mechanism is located.

[0051] The second implementation method applying the double crank-slider principle. When the bacteria grow to a certain period, a nail plate or a needle plate is used to punch holes on the surface of the bacteria bag, which can increase oxygen, improve the ventilation condition, and promote the development of hyphae. A punching needle 44 is fixedly connected to the end of the movable bar 18 where the second double crank-slider mechanism is located, and an elastically telescopic limiting rod 42 is installed on the movable plate 17. Since the sliding speed of the movable plate 17 inside the slide rail 21 is relatively small compared to the sliding speed of the movable bar 18 on the movable plate 17, and the length of the punching needle 44 is less than the length of the limiting rod 42. When the movable plate 17 drives the limiting rod 42 to contact the outer wall of the bacteria rod at a relatively slow speed to fix it, then the movable bar 18 drives the punching needle 44 to quickly insert into the bacteria rod to complete the punching. At the same time, due to the speed of the limiting rod 42 and the action of the second spring 43, when the punching needle 44 is pulled out instantaneously, the limiting rod 42 still fits with the outer wall of the bacteria rod to limit and fix it, thus greatly improving the stability of the insertion and extraction process of the punching needle 44. On the one hand, the possibility of damage to the punching needle 44 can be reduced. On the other hand, the quality of the punched holes is improved.

[0052] Specifically, a material guiding frame 39 is installed on the upper surface of the bottom plate 37 through a fixed rod, and the material guiding frame 39 is arranged in the middle of the support frame 38.

[0053] By setting the slope of the material guiding frame 39 and arranging the material guiding frame 39 in the middle of the support frame 38, when the bacteria rod slides downward on the slope of the material guiding frame 39, the automatic feeding of the bacteria rod during the punching process can be realized. Cooperating with the contact and limiting frequency of the limiting rod 42 with the bacteria rod, holes with different densities can be punched, greatly improving the problems of low efficiency and poor quality in the existing punching of bacteria rods.

[0054] Working principle: When the bacteria rod punching and inoculation device based on the double crank-slider principle is used, as Figure 1When the punching cylinder 22 in this state has already been filled with the bacterial material for single inoculation, then the mushroom stick to be punched and inoculated is placed between the two mounting plates 9 and supported by the baffle 10. After that, the telescopic cylinders 36 are driven so that the two telescopic cylinders 36 can clamp the two ends of the mushroom stick. Then, the corresponding motor 2 on the side plate 3 is driven, and the motor 2 can further drive the rotating rod 14 to rotate. With the connection of the second connecting rod 13 and the third connecting rod 15, when the rotating rod 14 drives the second connecting rod 13 to swing, on the one hand, the movable plate 17 can slide inside the slide rail 21, and on the other hand, the movable strip 18 can slide relatively on the movable plate 17. Since the first connecting rod 12 and the fourth connecting rod 16 are at different connection points of the second connecting rod 13, the sliding rate of the movable plate 17 inside the slide rail 21 is relatively smaller than the sliding rate of the movable strip 18 on the movable plate 17 at this time. Since the punching cylinder 22 is arranged on the movable plate 17, the cross bar 19 is arranged on the movable strip 18, and there is a distance difference between the push block where the guide rod 24 is located and the insertion part of the punching cylinder 22, that is, when the punching cylinder 22 moves and inserts into the mushroom stick to complete punching, then the subsequent guide rod 24 drives the push block to push out the bacterial material inside the punching cylinder 22 and press it inside the mushroom stick, thus realizing the automatic punching and inoculation process.
