Stable fungus frame racking machine

Abstract

The invention relates to the field of fungus frame racking, in particular to a stable fungus frame racking machine, the bottom of a fungus frame is usually supported on a movable bearing roller, although a fixing device is arranged on the upper portion of the fungus frame, in the lifting motion, due to the mobility of the bearing roller, the fungus frame can still generate micro displacement or shaking, the fungus frame is separated from a fixing point, and therefore the fungus frame can not be separated from the fixing point. And safety risks in professional conveying of the fungus frames are further caused. When the mushroom frame is horizontally positioned and locked with the locking mechanism, the supporting of the bottom of the mushroom frame and the supporting rollers is converted into static friction from rolling friction, so that the risk of displacement and shaking of the mushroom frame caused by accidental rotation of the supporting rollers in the lifting process is eliminated, and the stability and the safety in the carrying process are improved.

Description

Technical Field

[0001] This invention relates to the field of mushroom basket loading, specifically a stable mushroom basket loading machine. Background Technology

[0002] Due to their rich nutritional value and economic benefits, the industrialized and large-scale production of edible fungi has become a mainstream trend worldwide. In this production model, loading the inoculated substrate into specialized mushroom baskets (or mushroom trays) and transferring these baskets to multi-layer cultivation racks for mycelial growth management is a crucial and extremely labor-intensive process.

[0003] In existing transfer processes, lifting equipment is typically used to raise the culture trays containing the culture medium to the corresponding level on the culture rack. To prevent the trays from vibrating or slipping during the lifting process, they are usually fixed to the lifting rack. However, the current design has certain potential risks: The bottom of the mushroom basket is usually supported on a movable support roller. Although there is a fixing device on the top, the mushroom basket may still be slightly displaced or shaken during the lifting and lowering process due to the mobility of the support roller, which may cause it to detach from the fixing point and thus bring safety risks in the professional conveying of mushroom baskets. Summary of the Invention

[0004] The purpose of this invention is to provide a stable mushroom frame loading machine to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a stable mushroom frame loading machine, comprising mushroom frames, which are conveyed towards a lifting device via a conveyor. The lifting device is equipped with a vertical guide rail and a lifting platform that can slide along it. The lifting platform is driven by a servo motor-driven screw module to achieve vertical lifting motion. A pair of guide plates are symmetrically arranged on the lifting platform for supporting and aligning the mushroom frames. The guide plates are equipped with a locking mechanism for pressing and fixing the mushroom frames onto the lifting platform. A support roller for supporting the bottom of the mushroom frames is rotatably installed between the two guide plates. A braking component is provided on the inner side of the guide plates corresponding to the end of the support roller. When the locking mechanism is activated, it drives the braking component to lock the support roller to prevent it from rotating, thereby providing stable bottom support for the mushroom frames.

[0005] Preferably, the locking mechanism includes a fixed seat fixedly installed on the guide plate, the fixed seat having a guide cavity, a push rod that can move axially is slidably installed in the guide cavity through a compression spring, the end of the push rod having an elastically retractable wedge-shaped locking pin, and a locking slot matching the wedge-shaped locking pin being opened at a corresponding position along the transverse axis of the push rod on the fixed seat.

[0006] Preferably, the braking assembly includes a drive slider slidably mounted on the bottom of the fixed base, the bottom of the push rod extends and is fixedly connected to the drive slider, the drive slider is provided with a linear guide groove, the fixed base is rotatably connected to a rotating shaft, the end of which is fixedly mounted with a swing arm, the swing arm is provided with a guide roller that rolls along the linear guide groove, and the end of the rotating shaft is provided with a stop part for locking the support roller.

[0007] Preferably, the stopping part includes a brake arm fixedly mounted on the rotating shaft, a locking pin guide rod is radially slidably mounted on the brake arm, a return spring is provided between the locking pin guide rod and the brake arm, a positioning boss is provided on the outer wall of the fixed seat, a plurality of wedge-shaped locking grooves are evenly opened on the end face of the support roller along the circumference, and a wedge-shaped plug adapted to the wedge-shaped locking groove is provided at the end of the locking pin guide rod.

[0008] Preferably, the stopping part includes a brake swing bracket fixedly mounted on a rotating shaft. A clamping rod is hinged to the brake swing bracket via a rotating shaft. A torsion spring is fitted on the rotating shaft to ensure that the clamping rod is always subjected to a compressive torque. A cam disk is fixed to the outer wall of the fixed seat. The working surface of the cam disk is a spiral ridge that changes continuously from low to high. A follower roller that can roll along the spiral ridge is mounted on the upper end of the clamping rod. A hard alloy extrusion head is embedded in the lower end of the clamping rod. A wear-resistant friction plate is mounted on the end face of the support roller.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the flat end of the wedge-shaped locking pin forms a firm planar contact with and engages with the inner wall of the locking port, thereby reliably locking the mushroom frame onto the guide tray and completing the automatic locking. This locks the mushroom frame onto the guide tray, preventing it from shifting slightly in the air, and enabling the lifting equipment to accurately transport and place the mushroom frame at the designated stacking position, ensuring the neatness and stability of the stack and providing a foundation for subsequent automated stacking.

[0010] In this invention, while the mushroom frame is horizontally positioned and locked with the locking mechanism, the support between its bottom and the support roller is changed from rolling friction to static friction. This eliminates the risk of displacement and shaking of the mushroom frame caused by accidental rotation of the support roller during the lifting process, and improves the stability and safety of the handling process.

[0011] In this invention, the engagement of the wedge-shaped plug and the wedge-shaped locking groove achieves high surface contact locking strength, effectively preventing accidental loosening caused by vibration during the lifting process and improving the safety of the mushroom frame lifting process. The multiple wedge-shaped locking grooves arranged around the support rollers ensure that the brake arm can quickly find the locking position at any rotation angle. The wedge-shaped pins and locking ports ensure the precise positioning of the mushroom frame on the horizontal plane and prevent its lateral movement. After the support rollers are fixed by the wedge-shaped plugs, they transform from rolling elements into sturdy support seats, providing reliable axial support for the bottom of the mushroom frame and improving the rigidity and stability of the mushroom frame during the conveying process.

[0012] In this invention, the support rollers are locked in a progressive manner. During the brief period before the mushroom frame is fully locked, the gradually increasing braking force provides a gradual increase in rolling resistance to the support rollers. The damping effect makes the transition of the mushroom frame from free rolling to complete stillness smoother, preventing the mushroom frame from shifting due to inertia during docking on the guide plate, and further ensuring its positioning accuracy.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1 Please see Figures 1 to 12 This invention provides a technical solution: a stable mushroom frame mounting machine, including a mushroom frame 1. The mushroom frame 1 is conveyed towards a lifting device 12 via a conveyor 11. The lifting device 12 is provided with a vertical guide rail and a lifting platform 13 that can slide along it. The lifting platform 13 is driven by a servo motor-driven screw module to achieve vertical lifting motion. A pair of guide plates 14 are symmetrically arranged on the lifting platform 13 for supporting and aligning the mushroom frame 1. The guide plates 14 are provided with a locking mechanism 2 for pressing and fixing the mushroom frame 1 onto the lifting platform 13. A support roller 15 for supporting the bottom of the mushroom frame 1 is rotatably installed between the two guide plates 14. A braking component 3 is provided on the inner side of the guide plates 14 corresponding to the end of the support roller 15. When the locking mechanism 2 is activated, it drives the braking component 3 to lock the support roller 15 to prevent it from rotating, thereby providing a stable bottom support for the mushroom frame 1. During operation, the mushroom frame 1 is transported by the conveyor 11 to the predetermined position of the lifting platform 13 of the lifting device 12. The mushroom frame 1 moves along the guide plate 14 and is automatically pressed and fixed after contacting the locking mechanism 2. During this process, the bottom of the mushroom frame 1 rolls and contacts the support roller 15, effectively reducing frictional resistance and achieving smooth positioning. After locking, the braking component 3 locks the support roller 15 under the action of the locking mechanism 2, so that the dynamic friction is changed to static friction, providing a solid and reliable bottom support for the mushroom frame 1. The servo motor drives the screw module to drive the lifting platform 13 to lift smoothly along the vertical guide rail, accurately transporting the mushroom frame 1 to the designated height, providing positioning and support for subsequent automated palletizing operations.

[0017] In this embodiment, the locking mechanism 2 includes a fixed seat 21 fixedly installed on the guide plate 14. The fixed seat 21 has a guide cavity 22. A top rod 24 that can move axially is slidably installed in the guide cavity 22 through a compression spring 23. The end of the top rod 24 is provided with a wedge-shaped locking pin 25 that can be elastically extended and retracted. The fixed seat 21 has a locking port 26 that matches the wedge-shaped locking pin 25 at a corresponding position along the transverse axis of the top rod 24. During operation, the mushroom frame 1 is conveyed to the predetermined station along the guide plate 14. Its side edge contacts the end of the top rod 24 and applies pressure. The mushroom frame 1 pushes the top rod 24 to compress the spring 23 and move into the fixed seat 21. The top rod 24 drives the wedge-shaped pin 25 to move together towards the locking port 26. The inclined surface of the wedge-shaped pin 25 contacts the inner wall of the fixed seat 21, forcing it to contract. When the wedge-shaped pin 25 moves to align with the locking port 26, it quickly pops out under the restoring force of the compression spring 23, so that the flat end of the wedge-shaped pin 25 forms a firm planar contact with the inner wall of the locking port 26 and engages with it, thereby reliably locking the mushroom frame 1 onto the guide plate 14 and completing the automatic locking. The mushroom basket 1 is locked onto the guide tray 14 to prevent it from shifting slightly in the air. This allows the lifting device 12 to accurately transport and place the mushroom basket 1 at the designated stacking position, ensuring the neatness and stability of the stack and providing a foundation for subsequent automated stacking.

[0018] In this embodiment, the braking assembly 3 includes a drive slider 31 slidably mounted on the bottom of the fixed base 21. The bottom of the top rod 24 extends and is fixedly connected to the drive slider 31. A linear guide groove 32 is provided on the drive slider 31. A rotating shaft 33 is rotatably connected to the fixed base 21. A swing arm 34 is fixedly mounted at its end. A guide roller 35 that rolls along the linear guide groove 32 is provided on the swing arm 34. A stopping part 4 for locking and supporting the roller 15 is provided at the end of the rotating shaft 33. During operation, the mushroom frame 1 pushes the top rod 24 to move inward. The top rod 24 simultaneously drives the drive slider 31 to slide horizontally. The linear guide groove 32 on the drive slider 31 forces the guide roller 35 to move, thereby driving the swing arm 34 to rotate around the rotating shaft 33. The rotation of the rotating shaft 33 causes the stopping part 4 to press against the end face of the support roller 15. By locking the end of the support roller 15, the support roller 15 is effectively prevented from continuing to rotate. While the mushroom frame 1 is horizontally positioned and locked with the locking mechanism 2, the support between its bottom and the support roller 15 changes from rolling friction to static friction. This eliminates the risk of displacement and shaking of the mushroom frame 1 caused by accidental rotation of the support roller 15 during the lifting process, and improves the stability and safety of the handling process.

[0019] In this embodiment, the stopping part 4 includes a brake arm 41 fixedly installed on the rotating shaft 33. A locking pin guide rod 42 is radially slidably installed on the brake arm 41. A return spring 43 is provided between the locking pin guide rod 42 and the brake arm 41. A positioning boss 44 is provided on the outer wall of the fixed seat 21. A plurality of wedge-shaped locking grooves 45 are evenly opened on the end face of the support roller 15 along the circumference. A wedge-shaped plug 46 that matches the wedge-shaped locking grooves 45 is provided at the end of the locking pin guide rod 42. During operation, the locking process of the mushroom frame 1 drives the rotating shaft 33 to rotate, which in turn drives the brake arm 41 to swing synchronously. When the end of the locking pin guide rod 42 contacts the positioning boss 44 on the fixed seat 21 under the action of the return spring 43, the guide rod is subjected to radial thrust, which drives the wedge plug 46 to be precisely inserted into the wedge locking groove 45 on the end face of the support roller 15. The wedge surface ensures that the wedge plug 46 is smoothly inserted and tightly engaged, thereby realizing the circumferential positioning and locking of the support roller 15. The engagement of the wedge plug 46 and the wedge locking groove 45 achieves high surface contact locking strength, which can effectively prevent accidental loosening caused by vibration during the lifting process and improve the safety of the mushroom frame 1 during the lifting process. The multiple wedge locking grooves 45 arranged around the support roller 15 ensure that the brake arm 41 can quickly find the locking position at any rotation angle. The wedge pin 25 and the locking port 26 ensure the precise positioning of the mushroom frame 1 on the horizontal plane and prevent its lateral movement. After the support roller 15 is fixed by the wedge plug 46, it transforms from a support roller 15 into a sturdy support seat, providing reliable axial support for the bottom of the mushroom frame 1 and improving the rigidity and stability of the mushroom frame 1 during the conveying process.

[0020] Example 2 To further improve the locking reliability of the support roller 15 to the bottom of the mushroom frame 1 and enhance its adaptability to different working conditions; Specifically, in Embodiment 1, the stopping part 4 provides high-strength instant locking through the rigid engagement of the wedge plug 46. However, considering the slight skew or vibration that may exist during the conveying and positioning of the mushroom frame 1, a brake that can provide progressive clamping force can achieve locking more smoothly and further improve the overall stability of the mushroom frame 1 during the conveying process.

[0021] Accordingly, Figures 11-12 As shown, this application provides an improved embodiment with four stopping parts: In this embodiment, the stopping part 4 includes a brake swing bracket 5 fixedly installed on the rotating shaft 33. A clamping rod 51 is hinged to the brake swing bracket 5 via the rotating shaft 33. A torsion spring 52 is fitted on the rotating shaft 33 so that the clamping rod 51 is always subjected to a compressive torque. A cam disk 53 is fixed on the outer wall of the fixed seat 21. The working surface of the cam disk 53 is a spiral ridge 54 that changes continuously from low to high. A follower roller 55 that can roll along the spiral ridge 54 is installed at the upper end of the clamping rod 51. A hard alloy extrusion head 56 is embedded at the lower end of the clamping rod 51. A wear-resistant friction plate 57 is installed on the end face of the support roller 15. During operation, the mushroom frame 1 gradually compresses the locking mechanism 2, driving the rotating shaft 33 to rotate, which in turn drives the brake swing frame 5 to swing synchronously. Under the action of the torsion spring 52, the follower roller 55 on the clamping rod 51 always rolls in close contact with the spiral ridge 54 of the cam disk 53. As the height of the spiral ridge 54 continuously increases, the rolling process forces the clamping rod 51 to gradually rotate around its rotation axis 33, causing the hard alloy extrusion head 56 at its lower end to gradually press the wear-resistant friction plate 57 on the end face of the support roller 15. The resulting frictional torque continues to increase, thereby applying damping to the rotation of the support roller 15 until the mushroom frame 1 is fixed to the locking mechanism 2 and the support roller 15 is completely locked. By gradually locking the support roller 15, the gradually increasing braking force provides a gradual increase in rolling resistance to the support roller 15 during the brief period before the mushroom frame 1 is completely locked. The damping effect makes the transition of the mushroom frame 1 from free rolling to complete stillness smoother, avoiding the mushroom frame 1 from shifting due to inertia during docking on the guide plate 14, and further ensuring its positioning accuracy.
