Description

Technical Field

[0001] This utility model belongs to the field of edible fungi cultivation technology, specifically relating to a device for pushing in hollow oxygen supply rods inside mushroom substrate. Background Technology

[0002] During the cultivation of mushroom spawn, hollow sticks are inserted into the opening of the spawn log. This serves two purposes: sealing and securing the log, and ensuring air circulation between the inside and outside of the log. A conveyor belt is typically used to assist in inserting the hollow sticks. Above the conveyor belt is a pusher for inserting the hollow sticks into the opening, and behind the pusher is a top plate for further pushing the hollow sticks into the log. The pusher and top plate work together to push the hollow sticks into the log. Different sized spawn logs require different sized hollow sticks. During operation, the pusher inserts its end into the inner hole of the hollow stick and pushes the stick downwards into the log. However, during the pushing process of the hollow rod, especially when the hollow rod moves into the inside of the mushroom stick, the resistance is relatively large. When the size of the top rod end does not match the size of the inner hole of the hollow rod, the top rod end is prone to getting stuck in the inner hole of the hollow rod. When the top rod moves upward, it will cause the hollow rod to move upward as well. This will cause interference during the conveying process of the mushroom stick, affecting the normal conveying. In severe cases, it may also cause interference and damage to the mushroom stick or components on the equipment. Utility Model Content

[0003] This utility model provides a device for pushing in hollow oxygen supply rods inside mushroom sticks, which aims to solve the problem in the prior art that when inserting hollow rods into mushroom sticks, the hollow rods are easily pulled out or the mushroom sticks are displaced, affecting subsequent rod insertion operations.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a device for pushing in hollow oxygen supply rods inside mushroom substrate, comprising:

[0005] frame;

[0006] A conveyor belt, installed on the frame, is used to transport the mushroom logs horizontally;

[0007] A support frame is installed directly above the conveyor belt. The support frame is provided with a first elastic material support component and a second elastic material support component in sequence along the vertical direction for supporting hollow bars.

[0008] A pressure plate is slidably mounted on the frame in a vertical direction, and a drive assembly for moving the pressure plate is also installed on the frame;

[0009] The top rod is fixedly installed on the pressure plate, and its length direction is set along the vertical direction;

[0010] An inlet component is detachably installed at the bottom end of the top rod. The inlet component includes a guide portion that can slide into the inner hole of the hollow rod and a pushing portion with an outer diameter larger than the guide portion.

[0011] A push-in plate, installed on the pressing plate, is used to press the hollow rod into the inside of the mushroom stick.

[0012] In one possible implementation, a screw is fixedly installed at the end of the inlet member away from the guide portion, the end of the push rod is provided with a corresponding threaded hole, and the push portion can abut against the end of the push rod.

[0013] In one possible implementation, a guide protrusion is fixedly installed at the end of the pushing part away from the guiding part. The guide protrusion is coaxially arranged with the screw, and the end of the push rod is provided with a guide hole corresponding to the guide protrusion.

[0014] In one possible implementation, the position of the support rod on the frame has a degree of freedom that can be adjusted in the vertical direction.

[0015] In one possible implementation, a gear is rotatably mounted on the frame, and a rack that meshes with the gear is also fixedly mounted on the support frame.

[0016] In one possible implementation, a first worm gear is fixedly mounted on the rotating shaft of the gear, the first worm gear is coaxially arranged with the gear, and a first worm is rotatably arranged on the frame, meshing with the first worm gear.

[0017] In one possible implementation, a guide rail arranged vertically is fixedly mounted on the frame, and a slider that is slidably mounted on the guide rail is fixedly mounted on the support frame.

[0018] In one possible implementation, the driving component includes:

[0019] The lead screw is arranged vertically along its length and is rotatably mounted on the frame;

[0020] A threaded sleeve is threadedly connected to the lead screw and is fixedly mounted on the pressure plate;

[0021] A power unit, mounted on the frame, is used to drive the lead screw to rotate.

[0022] In one possible implementation, the power unit includes:

[0023] The second worm gear is fixedly connected to the lead screw and is coaxially arranged with the lead screw;

[0024] The second worm is rotatably mounted on the frame and meshes with the second worm wheel;

[0025] A drive component is mounted on the frame, and the drive end of the drive component is connected to the second worm gear transmission to drive the second worm gear to rotate.

[0026] In one possible implementation, the first elastic support assembly includes:

[0027] There are two material support plates, which are hinged to each other on the support rod frame, and the two material support plates form a feeding gap for accommodating the hollow rod.

[0028] An elastic element is installed between the material support plate and the support rod frame to drive the material support plate to flip upward and abut against the support rod frame.

[0029] The solution shown in this application embodiment, compared with the prior art, involves setting up a frame with a conveyor belt mounted on it. Baffles for guiding the mushroom logs are provided on both sides of the conveyor belt, and a support frame is positioned directly above the conveyor belt. The support frame includes a first elastic material support component and a second elastic material support component. The support frame is located at the output end of the hollow log conveying mechanism. When the hollow log moves onto the support frame, the flange at the opening of the hollow log overlaps with the first elastic material support component, and the hollow log is pressed downwards by a push rod, passing through the second elastic material support component and inserted into the mushroom log. The conveyor belt then moves the mushroom log to the next station, where a push plate inserts the hollow log into place. In this application, an inlet component is detachably installed at the bottom of the push rod. The bottom end of the inlet component is a guide portion that slides with the inner hole of the hollow log. A push portion is fixedly connected to the top of the guide portion, and the outer diameter of the push portion is larger than the outer diameter of the guide portion. Therefore, when the hollow log is pushed into the mushroom log, the push portion can abut against the end of the hollow log and drive the hollow log downwards. The hollow rod is inserted into the mushroom stick. When the top rod moves upward, the guide part slides into the inner hole of the hollow rod, allowing the guide part to smoothly detach from the hollow rod. This prevents the guide part from getting stuck inside the hollow rod and affecting the position of the hollow rod and the normal operation of subsequent work when it moves upward.

[0036] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] Please refer to the following: Figures 1 to 4 The present invention provides a device for pushing in hollow tubes for oxygen supply inside mushroom substrates. The device includes a frame 1, a conveyor belt 2, a tube support frame 3, a pressure plate 4, a top rod 5, an inlet component 51, and a pushing plate 6. A conveyor belt 2 is installed on the frame 1 for conveying mushroom sticks horizontally; a support frame 3 is installed directly above the conveyor belt 2, and the support frame 3 is vertically arranged with a first elastic support component 32 and a second elastic support component for supporting hollow sticks; a pressure plate 4 is slidably installed on the frame 1 vertically, and a drive component 7 for pushing the pressure plate 4 to move is also installed on the frame 1; a top rod 5 is fixedly installed on the pressure plate 4, and its length is vertically arranged; an inlet component 51 is detachably installed at the bottom end of the top rod 5, and the inlet component 51 includes a guide part 511 that can slide into the inner hole of the hollow stick and a pushing part 512 with an outer diameter larger than the guide part 511; a push plate 6 is installed on the pressure plate 4 for pressing the hollow stick into the inside of the mushroom stick.

[0038] The hollow rod pushing device for internal oxygen supply in this embodiment, compared with the prior art, features a frame 1 with a conveyor belt 2 mounted on it. Baffles for guiding the mushroom rods are located on both sides of the conveyor belt 2. A rod support frame 3 is positioned directly above the conveyor belt 2, comprising a first elastic material support component 32 and a second elastic material support component. The rod support frame 3 is located at the output end of the hollow rod conveying mechanism. When the hollow rod moves onto the rod support frame 3, the flange at the opening of the hollow rod overlaps with the first elastic material support component 32. A push rod 5 moves downwards, pressing the hollow rod through the second elastic material support component and inserting it into the mushroom rod. The conveyor belt 2 then moves the mushroom rod to the next station, where a push plate 6 inserts the hollow rod into place. In this application, an inlet component 51 is detachably installed at the bottom end of the top rod 5. The bottom end of the inlet component 51 is a guide portion 511 that slides with the inner hole of the hollow rod. A pushing portion 512 is fixedly connected to the top end of the guide portion 511. The outer diameter of the pushing portion 512 is larger than the outer diameter of the guide portion 511. Therefore, when the hollow rod is pushed into the mushroom substrate, the pushing portion 512 can abut against the end of the hollow rod and drive the hollow rod to move downwards. This allows the hollow rod to be inserted into the mushroom substrate. When the top rod 5 moves upwards, the guide portion 511 slides with the inner hole of the hollow rod, allowing the inlet component 51 to smoothly disengage from the hollow rod. This prevents the inlet component 51 from getting stuck inside the hollow rod and affecting the position of the hollow rod and the normal operation of subsequent work when moving upwards.

[0039] Specifically, in this embodiment, the inlet member 51 is detachably installed at the bottom of the top rod 5, so that the inlet member 51 of the corresponding size can be replaced according to the hollow rod of different sizes. On the one hand, the hollow rod can be positioned and guided by the guide part 511 on the inlet member 51, and on the other hand, the hollow rod can be pushed into the inside of the mushroom stick by the push part 512 on the inlet member 51.

[0040] Preferably, in this embodiment, the end of the inlet member 51 is a hemispherical structure that facilitates sliding into the inner hole of the hollow rod.

[0041] In some embodiments, the importer 51 described above may be as follows: Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 The end of the guide member 51 away from the guide portion 511 is also fixedly mounted with a screw 513. The end of the push rod 5 is provided with a corresponding threaded hole, and the pushing portion 512 can abut against the end of the push rod 5. The screw 513 is fixedly mounted on the end of the guide member 51, and the screw 513 is coaxially arranged with the guide portion 511 and the pushing portion 512 on the guide member 51. When it is necessary to install the guide member 51 to the end of the push rod 5, the screw 513 can be installed into the corresponding threaded hole of the push rod 5, and the pushing portion 512 can abut against the end of the push rod 5, thereby achieving the fixation between the guide member 51 and the push rod 5.

[0042] In some embodiments, the importer 51 described above may be as follows: Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 A guide protrusion 514 is fixedly installed at the end of the pushing part 512 away from the guide part 511. The guide protrusion 514 is coaxially arranged with the screw 513, and the end of the push rod 5 is provided with a guide hole corresponding to the guide protrusion 514. The guide protrusion 514 is fixedly installed at the end of the pushing part 512. When the guide member 51 is installed on the push rod 5, the guide protrusion 514 slides into the guide hole. This not only positions the guide member 51 at the end of the push rod 5, but also strengthens the connection between the screw 513 and the pushing part 512, preventing breakage at the connection between the screw 513 and the pushing part 512 during use.

[0043] In some embodiments, the aforementioned support bracket 3 may be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The position of the support rod 3 on the frame 1 is adjustable vertically. This vertical adjustment allows the position of the support rod 3 on the frame 1 to be adjusted according to the length of the hollow rod. This ensures that when the flange at the end of the hollow rod falls above the first elastic support assembly 32, the bottom end of the hollow rod is above the mushroom substrate. When the flange on the hollow rod falls above the second elastic support assembly, the bottom end of the hollow rod slides into the mushroom substrate. This prevents interference between the hollow rod and the mushroom substrate when it falls onto the support rod 3. The position of the support rod 3 can be freely adjusted according to the length of the hollow rod.

[0044] In some embodiments, the aforementioned support rod 3 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 A gear 11 is rotatably mounted on the frame 1, and a rack 31 meshing with the gear 11 is fixedly mounted on the support rod 3. The gear 11 is rotatably mounted on the side of the frame 1 near the support rod 3, and the rack 31 meshing with the gear 11 is fixedly mounted on the support rod 3. The length of the rack 31 is vertical. The axis of the gear 11 is horizontal and perpendicular to the length of the rack 31. When the drive gear 11 rotates on the frame 1, it drives the rack 31 to move, thereby moving the support rod 3 up and down to adjust its height.

[0045] In some embodiments, the aforementioned support rod 3 may be adopted as follows: Figure 3 The structure shown. See also Figure 3A first worm gear 12 is fixedly mounted on the rotating shaft of gear 11, and the first worm gear 12 is coaxially arranged with gear 11. A first worm 13, which meshes with the first worm gear 12, is also rotatably mounted on the frame 1. The first worm gear 12 is fixedly mounted on one side of gear 11 and is coaxially arranged with gear 11. The first worm 13 is also rotatably mounted on the frame 1, and the first worm 13 meshes with the first worm gear 12. A knob is fixedly mounted at the end of the first worm 13 to facilitate its rotation. When it is necessary to adjust the height of the support frame 3, the operator can manually rotate the knob, which will drive the first worm 13 to rotate. The first worm 13 will drive the first worm gear 12 to rotate, thereby driving gear 11 to rotate. When gear 11 rotates, the rack 31 meshing with gear 11 will move vertically, thereby adjusting the height of support frame 3.

[0046] In some embodiments, the aforementioned support rod 3 may be adopted as follows: Figure 1 , Figure 2 and Figure 3 The structure shown. See also... Figure 1 , Figure 2 and Figure 3 A vertically oriented guide rail 14 is fixedly mounted on the frame 1, and the guide rail 14 has clearance holes to allow the rotation shaft of the gear 11 to pass. A slider 33 is fixedly mounted on the support rod 3 and slidably mounted on the guide rail 14. Two guide rails 14 are fixedly mounted on the frame 1, with the gear 11 located between the two guide rails 14. The guide rails 14 also have clearance holes to allow the rotation shaft of the gear 11 to pass. The slider 33 is also fixedly mounted on the support rod 3 and slidably mounted on the guide rail 14, thereby guiding the movement direction of the support rod 3 and ensuring the stability of the displacement position of the support rod 3.

[0047] In some embodiments, the aforementioned actuating component may employ, for example... Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4The drive assembly 7 includes a lead screw 71, a threaded sleeve 72, and a power unit 73. The lead screw 71 is vertically oriented and rotatably mounted on the frame 1. The threaded sleeve 72 is threadedly connected to the lead screw 71 and fixedly mounted on the pressure plate 4. The power unit 73 is mounted on the frame 1 and drives the lead screw 71 to rotate. The lead screw 71 is rotatably mounted on one side of the frame 1, and the threaded sleeve 72 is threadedly connected to the lead screw 71 and fixedly mounted on the pressure plate 4. A push rod 5 and a guide rod for mounting the push plate 6 are fixedly mounted on the pressure plate 4. Both the guide rod and the push rod 5 are slidably mounted on the frame 1, thereby preventing the pressure plate 4 from rotating on the frame 1 around the axis of the lead screw 71. This ensures that the pressure plate 4 can move stably up and down. When the pressure plate 4 moves downward, it can synchronously drive the push rod 5 and the push plate 6 to move downward together. The mushroom sticks on the conveyor belt 2 will first pass under the top rod 5, and the hollow sticks will be pushed into the mushroom sticks by the top rod 5. Then, the mushroom sticks will be transported to the bottom of the push plate 6 by the conveyor belt 2, and the hollow sticks will be pressed into the mushroom sticks by the push plate 6, thus completing the installation of the hollow sticks inside the mushroom sticks.

[0048] Preferably, in this embodiment, the pusher plate 6 is located behind the top rod 5 along the transmission direction of the conveyor belt 2. When the pressure plate 4 moves downward, the top rod 5 and the pusher plate 6 can act synchronously on two adjacent mushroom sticks, improving the efficiency of inserting the hollow stick into the mushroom stick.

[0049] In some embodiments, the power unit 73 may employ, for example... Figure 4 The structure shown. See also Figure 4 The power unit 73 includes a second worm gear 731, a second worm 732, and a drive unit 733. The second worm gear 731 is fixedly connected to and coaxially arranged with the lead screw 71; the second worm 732 is rotatably mounted on the frame 1 and meshes with the second worm gear 731; the drive unit 733 is mounted on the frame 1, and its drive end is connected to the second worm 732 for driving the second worm 732 to rotate. The second worm gear 731 is fixedly mounted on the end of the lead screw 71 and coaxially arranged with it. The second worm 732 is also rotatably mounted on the frame 1, and meshes with the second worm gear 731. The drive unit 733 is a motor, and its drive end is connected to the second worm 732. The lifting and lowering state and position of the pressure plate 4 are controlled by controlling the working state of the drive unit 733. This makes it easier to control the position and state of the pressure plate 4 according to the size of the hollow bar.

[0050] In some embodiments, the first elastic material support component 32 described above may employ, as follows: Figure 2 The structure shown. See also Figure 2The first elastic material support assembly 32 includes a material support plate 321 and an elastic element 322. There are two material support plates 321, which are hinged to each other on the rod support frame 3, forming a feeding gap to accommodate the hollow rod. The elastic element 322 is installed between the material support plate 321 and the rod support frame 3, driving the material support plate 321 to flip upwards and abut against the rod support frame 3. A U-shaped groove is provided on the rod support frame 3 to avoid the hollow rod. Material support plates 321 are installed on both sides of the U-shaped groove, with the side of the material support plate 321 furthest from the U-shaped groove hinged to the rod support frame 3. The material support plates 321 on both sides of the U-shaped groove form a feeding gap to accommodate the hollow rod. The size of the feeding gap is larger than the outer diameter of the hollow rod but smaller than the outer diameter of the flange at the end of the hollow rod, allowing the hollow rod to overlap between the two material support plates 321 in a free state. When the top rod 5 is pressed down, the flange on the hollow rod is subjected to a downward force to open the two material support plates 321. After the flange on the hollow rod is separated from the first elastic material support assembly 32, the material support plate 321 is pressed against the material support frame by the elastic element 322.

[0051] Preferably, in this embodiment, an overlapping plate extends outward from the support rod frame 3, a U-shaped groove is located on the overlapping plate, and the material support plate 321 is hinged to the bottom of the overlapping plate, and the material support plate 321 can abut against the bottom of the overlapping plate to limit the position of the material support plate 321. The elastic element 322 is a torsion spring, one end of the torsion spring is attached to the material support plate 321, and the other end is attached to the bottom of the overlapping plate, for pushing the material support plate 321 to swing upward and abut against the bottom of the overlapping plate.

[0052] Specifically, in this embodiment, the second elastic material support component is located below the first elastic material support component 32 and has the same structure as the first elastic material support component 32.

[0053] Specifically, in this embodiment, the width of the discharge gap is greater than the maximum outer diameter of the push rod 5 and the guide member 51. This is to avoid affecting the upward movement of the push rod 5.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
