Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of frame turning machines, in particular to an edible mushroom frame turning machine. BACKGROUND

[0002] The edible mushroom frame turning machine (hereinafter referred to as the frame turning machine) is an important automated equipment on the factory edible mushroom production line, mainly used to complete the transfer and 180-degree turning of the mushroom basket between different processes such as inoculation, cultivation, and mushroom picking. In the process of factory cultivation of edible mushrooms, mycelial growth and mushroom production are carried out in special plastic baskets. However, the opening direction of the mushroom basket is opposite during inoculation (introducing spores into the culture medium) and mushroom picking (removing old spores to stimulate mushroom production). Therefore, the function of the frame turning machine is to automatically, efficiently, and smoothly turn the mushroom basket 180 degrees at a specific node on the production line to achieve process connection.

[0003] The interchangeable frame turning machine is a common and efficient frame turning machine. The main working process is as follows: the conveying mechanism sends the mushroom basket full of mushroom sticks to the frame turning station. After the frame turning machine grabs the mushroom basket, it is connected with the empty mushroom basket above. Then the whole is turned 180 degrees, so that the mushroom stick falls into the empty mushroom basket under the action of gravity, completing the turning. Finally, the turned mushroom basket is sent back to the conveying mechanism to realize automatic circulation.

[0004] In the prior art, the frame turning machine takes and places the mushroom basket and the connection of the mushroom basket mostly depends on fixed clamps or mechanical limiters. The corresponding conveying mechanism usually adopts a gap conveying mode to provide a static working condition for the frame turning machine. However, this method not only limits the improvement of the production efficiency of the whole line, but also causes frequent start and stop of the production line, aggravating the wear and tear of the machinery, thereby easily reducing the positioning accuracy and affecting the accuracy of the mushroom basket taking and placing.

[0005] Therefore, there is an urgent need for a frame turning device that can adapt to a continuous conveying mode, stably, accurately and efficiently complete the grabbing, turning and returning of the mushroom basket under dynamic conditions, to fully meet the long-term efficient, stable and reliable operation requirements of the edible mushroom production line. SUMMARY

[0006] This invention provides a mushroom basket flipping machine, which works in conjunction with a roller conveyor mechanism. It includes a flipping basket and two sets of pick-up and placement fixing mechanisms, arranged opposite each other on both sides of the flipping basket. Each pick-up and placement fixing mechanism includes a lifting frame with a longitudinally sliding support seat, a longitudinal reference, an active clamping structure, a transverse reference, a passive clamping structure, and a speed-reducing structure. The lifting frame raises and lowers, causing the support seat to pass through the gaps in the conveyor rollers, thus completing the pick-up and placement of the mushroom basket. The longitudinal reference is fixed to the lifting frame, serving as a fixed reference surface for the longitudinal positioning of the mushroom basket. The active clamping structure extends longitudinally... The movable mounting mechanism is installed on the lifting frame and used to press the mushroom baskets against it, ensuring the baskets are flush against the longitudinal reference. Both the transverse reference and the passive pressing structure are mounted on the lifting frame and pass through the gaps in the conveyor rollers as the frame rises and falls. The transverse reference passes through the gaps in the conveyor rollers before the passive pressing structure during the lifting frame's ascent, intercepting the conveyed mushroom baskets and initially positioning them laterally. The passive pressing structure is linked to the active pressing structure; when the active pressing structure performs its longitudinal pressing action, it drives the passive pressing structure to press against the mushroom basket laterally, ensuring the baskets are flush against the transverse reference. A deceleration structure is installed on the lifting frame and adaptively increases the resistance of the mushroom baskets until they are intercepted by the transverse reference.

[0007] In one possible implementation, the flipping frame is provided with a reinforcing limiting member. The reinforcing limiting member is bent and at least hinged to two longitudinal sides of the flipping frame. During the process of the mushroom basket abutting against the flipping frame, one end of the reinforcing limiting member first abuts against the mushroom basket and rotates as the mushroom basket moves. When the mushroom basket abuts against the flipping frame, the other end of the reinforcing limiting member limits the mushroom basket from the outside.

[0008] In one possible implementation, the deceleration structure includes symmetrically arranged hinges that are hinged to the lifting frame and connected to the lifting frame by an elastic restraint member, such that the symmetrical hinges are initially distributed in a V-shape, and the mushroom basket abuts against the lateral reference after passing through the symmetrical hinges.

[0009] In one possible implementation, the number of receiving seats is several and distributed sequentially along the direction of mushroom basket conveying, and the receiving seats are limited and slidably mounted on the lifting frame, and the receiving seats are automatically reset by setting an elastic reset member.

[0010] In one possible implementation, the receiving seat includes a longitudinal sliding body and a transverse sliding body, the transverse sliding body being slidably mounted on the longitudinal sliding body and in direct contact with the mushroom basket.

[0011] In one possible implementation, the passive abutment structure includes a laterally sliding limit head and a drive rod rotatably mounted with a gear on the same axis, the drive rod being threadedly connected to the limit head; the passive abutment structure also includes a linkage component fixedly mounted on the active abutment structure and meshing with the gear.

[0012] In a possible implementation, the number of the limit heads is at least two and symmetrically distributed in the longitudinal direction.

[0013] In a possible implementation, the lifting frame comprises symmetrically arranged track lifting parts and a plurality of sinking units fixed between the symmetrically arranged track lifting parts, and the track lifting parts on the same side of the two groups of taking and placing fixing mechanisms share a linear guide rail.

[0014] The above one or more technical solutions in the embodiments of the present application have the following technical effects: according to the edible mushroom frame turning machine provided by the embodiments of the present application, the taking and placing fixing mechanism first intercepts the mushroom basket, then separates the mushroom frame from the conveying mechanism, and then completes the positioning and fixing of the mushroom frame in linkage, and automatically forms six directions of front, rear, left, right, up and down, thereby quickly and accurately completing the docking of the upper and lower mushroom frames, improving the stability of the position state of the mushroom frame during the turning process, and reducing the frictional resistance in the adjusting process through the slidingly arranged receiving seat during the positioning and adjusting process of the mushroom frame, improving the convenience of the positioning process. In addition, in the process of intercepting the mushroom frame, the mushroom frame is stably and reliably intercepted through the speed reduction structure and the fixed transverse reference, and the frame turning machine stably, reliably and accurately completes the grabbing, docking and turning of the mushroom frame in the continuous conveying mode, and can fully meet the long-term, efficient, stable and reliable operation requirements of the edible mushroom production line.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond the specific embodiments described below, and a person skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0023] Please refer to Figure 1 A mushroom turnover machine cooperates with a roller conveying mechanism to automatically complete the taking and placing of the mushroom basket 4 and the turnover of the mushroom basket 4 in a continuous conveying process without stopping. The turnover machine includes a turnover frame 1 and two groups of taking and placing fixing mechanisms 2. The two groups of taking and placing fixing mechanisms 2 are oppositely arranged and respectively located at two sides of the turnover frame 1. In the initial state, one group of taking and placing fixing mechanisms 2 is located above and fixes an empty mushroom basket 4, and the other group of taking and placing fixing mechanisms 2 is located below.

[0024] When the roller conveying mechanism sends the mushroom basket 4 full of mushroom sticks into the turnover station, the lower taking and placing fixing mechanism 2 moves upward, lifts the mushroom basket 4 full of mushroom sticks to make it separate from the roller conveying mechanism, and continues to move upward until the mushroom basket 4 abuts against and is fixed on the turnover frame 1 and is aligned with the upper mushroom basket 4. In this process, the mushroom basket 4 full of mushroom sticks first completes accurate positioning and accurate alignment with the upper mushroom basket 4, and then, as the taking and placing fixing mechanism 2 continues to move upward, the top of the mushroom stick in the lower mushroom basket 4 gradually inserts into the inside of the upper mushroom basket 4, and then the lower mushroom basket 4 abuts against and is fixed on the turnover frame 1.

[0025] Then the turnover frame 1 is turned over by 180 degrees to exchange the positions of the upper and lower mushroom baskets 4. The mushroom sticks are synchronously turned over in the turnover process and automatically fall into the lower mushroom basket 4 under the action of gravity. After that, the lower taking and placing fixing mechanism 2 moves downward to make the turned-over mushroom basket 4 return to the roller conveying mechanism to continue conveying. When the new mushroom basket 4 full of mushroom sticks enters the turnover station, the above-mentioned process is repeated to realize cyclic operation. Through cooperation with the roller conveying mechanism, the present application efficiently, automatically and reliably completes the turnover process of the mushroom basket 4 on the basis of continuous conveying without stopping.

[0026] Referring to Figure 1 and Figure 2 , the taking and placing fixing mechanism 2 includes a lifting frame 22 longitudinally (front and back direction) slidingly provided with a receiving seat 21, as shown in Figure 2 , the lifting frame 22 includes a track lifting part 221 and a plurality of sinking units 222, the track lifting part 221 is symmetrically distributed front and back, the sinking units 222 are uniformly distributed along the conveying direction (left and right) and are fixedly installed between the symmetric track lifting parts 221, the sinking units 222 are opposite to the gap between the adjacent conveying rollers 3, the receiving seat 21 corresponds to the sinking unit 222 one by one and is slidingly installed on the corresponding sinking unit 222, and the plurality of receiving seats 21 constitute a non-continuous receiving surface for receiving the fungus basket 4, the track lifting part 221 on the rear side is fixedly installed with a longitudinal reference 23, and the track lifting part 221 on the front side is slidingly installed with a driving abutting structure 24, the driving abutting structure 24 is moved rearward to abut against the fungus basket 4 and make the fungus basket 4 closely adhere to the longitudinal reference 23, so as to realize the positioning and fixing of the fungus basket 4 in the longitudinal direction, the sinking unit 222 on the rightmost side is fixedly installed with a transverse reference 25, and the sinking unit 222 on the leftmost side is installed with a passive abutting structure 26, and the passive abutting structure 26 is linked with the driving abutting structure 24, in the process of moving the driving abutting structure 24 rearward to abut against the fungus basket 4, the passive abutting structure 26 can be driven to abut against the fungus basket 4 in the transverse direction and make the fungus basket 4 closely adhere to the transverse reference 25, so as to realize the positioning and fixing of the fungus basket 4 in the transverse direction, the aforementioned positioning and fixing process of the fungus basket 4 only needs one driving, and the overall structure is simple and has high correlation, so that the positioning and fixing of the fungus basket 4 can be quickly, stably and reliably completed, and after positioning and fixing, a limit is formed in the front, back, left and right directions, so as to ensure the stability of the position of the fungus basket 4, and in the process of positioning and fixing the fungus basket 4, the receiving seat 21 moves with the fungus basket 4, so as to effectively reduce the friction generated in the positioning and adjusting process of the fungus basket 4 and improve the convenience of the adjusting process, wherein the track lifting parts 221 on the same side of the two groups of taking and placing fixing mechanisms 2 share a straight track.

[0027] Referring to Figure 2 , the receiving seat 21 includes a longitudinal sliding body 211 and a transverse sliding body 212, the transverse sliding body 212 is transversely limitingly and slidingly installed on the longitudinal sliding body 211, and the transverse sliding body 212 directly contacts the fungus basket 4, and the longitudinal sliding body 211 and the transverse sliding body 212 are both provided with an elastic reset member 27 between the longitudinal sliding body 211 and the sinking unit 222 and between the longitudinal sliding body 211 and the transverse sliding body 212, the elastic reset member 27 is used to reset the longitudinal sliding body 211 forward and the transverse sliding body 212 leftward after the fungus basket 4 is separated from the transverse sliding body 212, so as to smoothly perform the next round of positioning and adjusting work and improve the convenience and reliability of the positioning and adjusting process.

[0028] Referring to Figure 2 ,Figure 3 and Figure 4 The height of the lateral reference 25 is higher than the passive abutting structure 26.

Then, the receiving seat 21 contacts the bottom of the mushroom basket 4 and receives the mushroom basket 4 to make it separate from the conveying roller 3. Then, the active abutting structure 24 moves backward to abut against the mushroom basket 4 to complete the longitudinal positioning and fixing. At the same time, the passive abutting structure 26 abuts against the mushroom basket 4 in the lateral direction to complete the positioning and fixing of the mushroom basket 4 in the lateral direction, so that the mushroom basket 4 is stably and accurately aligned with the upper mushroom basket 4 and forms a limit for the mushroom basket 4 in the up-down direction, thereby improving the stability of the position state of the mushroom basket 4 and the stability and reliability of the whole flipping process. Figure 2 and Figure 3 The passive abutting structure 26 includes a limiting head 261 which is laterally (left-right direction) slidingly arranged on the leftmost sinking unit 222. The limiting head 261 is symmetrically distributed in front and back. The sinking unit 222 is provided with a driving rod 263 and a linkage 264. The driving rod 263 is rotationally installed on the sinking unit 222 and corresponds to the limiting head 261 in one-to-one manner. The limiting head 261 is threadedly connected with the corresponding driving rod 263. The driving rod 263 is coaxially provided with a gear 262. The linkage 264 is a strip provided with two toothed segments. The strip is fixedly connected with the active abutting structure 24. The gear 262 is engaged with the toothed segments on the strip. When the active abutting structure 24 moves backward, the linkage 264 moves backward and rotates the driving rod 263 through the gear 262. The driving rod 263 moves the limiting head 261 rightward to abut against the mushroom basket 4. The whole passive abutting structure has good stability and high strength, and can stably and accurately position and fix the mushroom basket 4 in the lateral direction.
