Description

Technical Field

[0001] The invention relates to a tremella picking device and a working method thereof. Background Art

[0002] As a traditional edible fungus in my country, Tremella fuciformis has always been a food deeply loved by the general public. The active ingredient contained in it, Tremella fuciformis polysaccharide, has special health care functions. The current picking method is mostly manual picking, which involves holding the mushroom seed in one hand and picking the Tremella fuciformis off the mushroom seed with the other hand to complete the picking of the Tremella fuciformis on the mushroom seed. The above method is relatively cumbersome and labor-intensive to operate, and only one Tremella fuciformis can be picked manually at a time, resulting in low work efficiency.

[0003] In the process of cultivating Tremella fuciformis, single flower and single pot are generally used for cultivation. In the process of cultivating Tremella fuciformis, single flower and single pot are generally used for cultivation. When picking is needed, it is usually necessary to manually arrange the Tremella fuciformis in a single pot in sequence at the feeding port of the picking station, which has low work efficiency. If a conveyor belt is used for transportation, it is easy to cause the transportation to fail to be automatically diverted, which will cause excessive accumulation at some feeding ports and no Tremella fuciformis at some feeding ports. Manual transportation is required, which is manpower-consuming and not conducive to the stable picking work with the picking device in step sequence. The use of the conveyor belt setting is also prone to the displacement of the Tremella fuciformis culture pot during transportation, that is, it cannot be transported to the picking station in the right position, which will affect the picking efficiency and increase the failure rate of picking.

[0004] The existing picking process is prone to interference between the clamping and picking parts, that is, after clamping, the white fungus part of the picking shovel is prone to shovel onto the clamping device, causing damage. If the clamping device is adjusted, the clamping will be unstable or the picking part will easily shovel too high, causing waste of white fungus. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description.

[0032] In the embodiment of the present invention, the conveyor line is arranged in parallel with the discharging conveyor line and both convey horizontally, and the branch conveyor lines of the conveyor line and the discharging conveyor line are bent at the joint for longitudinal conveying, that is, there are several picking mechanisms evenly spaced longitudinally, and since the tremella planting pots are placed in a tremella planting pot in a rectangular array, each picking mechanism corresponds to different rows of tremella planting pots, that is, the picking stations after being reset by the reset cylinder are not consistent, so that the picking work can be carried out more effectively and efficiently.

[0033] In the embodiment of the present invention, a longitudinal conveyor belt 24 for receiving Tremella fuciformis is provided at the side end of the branch conveyor line, and a material receiving box 36 for receiving Tremella fuciformis is provided at the end of the longitudinal conveyor belt.

[0034] In the embodiment of the present invention, a clamping opening is formed between the obliquely extended front clamping plate and the vertically arranged rear clamping plate member to facilitate clamping of white fungus. The clamping opening is small at the top and large at the bottom to accommodate white fungus arranged side by side when not clamped. The top end of the front clamping plate is fixedly connected to a longitudinally extended rotating rod, and the end of the rotating rod is connected to a swing cylinder via a push block. The swing cylinder extends laterally to drive the front clamping plate to swing close to the white fungus. Both ends of the rotating rod pass through the mounting frame and are rotatably connected to the same, that is, the degree of freedom of the rotating rod is limited by the mounting frame so that it can only swing under the action of the push block, thereby ensuring the swinging effect of the front clamping plate.

[0036] In the embodiment of the present invention, the picking cylinder is arranged between two fixed plates, and two groups of the picking cylinder are arranged between the two fixed plates in parallel. A longitudinally extending picking frame 16 is arranged at the transversely extending output end of the picking cylinder, and the picking rods are fixedly connected to the picking frame at intervals. The two fixed plates are provided with sliding grooves 17 for the picking frame to slide laterally.

A vertical guide limit rod 19 is fixedly provided on the top of the main body of the give way cylinder. A strip-shaped guide limit hole 20 is provided on the limit block for the guide limit rod to pass through and cooperate with. The lateral position of the rear splint is limited by the limit block to avoid excessive squeezing of the white fungus and damage.

[0038] In the embodiment of the present invention, a square mounting frame 21 is provided above the branch conveyor line, and a transverse slide rail 22 is fixed on the mounting frame to slide with both ends of the support plate, and the reset cylinder body is fixedly connected to the mounting frame.

[0039] In the embodiment of the present invention, the lifting cylinders are symmetrically provided with two groups, and their telescopic ends are connected to the connecting plate. The connecting plate is symmetrically fixed with two guide columns 23 extending vertically and penetrating the support plate, and the guide columns are slidably connected to the support plate.

[0040] In the embodiment of the present invention, the material shifting mechanism includes two fixed frames 30 respectively fixed on the conveyor line and the branch conveyor line or the branch conveyor line and the discharging conveyor line, and a slide rail 31 is horizontally arranged between the two fixed frames. A shifting plate 32 is slidably connected to the slide rail. The shifting plate is in an inverted L shape and is driven to slide back and forth on the slide rail by a shifting cylinder 33 fixed to the fixed frame. That is, the tremella planting pot is driven to slide along the conveyor roller by the contraction of the shifting cylinder until it slides to the branch conveyor line and stops to complete the diversion, which can effectively avoid the accumulation of the conveyor line and affect the work efficiency.

[0041] The conveyor line and the branch conveyor line discharge ends are both provided with vertically placed material-blocking cylinders, and a block 25 is fixedly arranged on the top of the material-blocking cylinder to limit the tremella planting pot; a slider 45 is fixedly arranged on the top of the horizontal section of the shift plate and is slidably connected to the slide rail through the top of the slider, a convex portion is arranged on the top of the slider, and the top of the convex portion extends toward both sides to facilitate hanging in the track groove at the lower end of the slide rail and sliding in the track groove, the transverse conveying end of the shifting cylinder is connected to the slider, and a sensor 37 is arranged on the slide rail above the branch conveyor line; correspondingly, a sensor for sensing whether the tremella planting pot is in place is also arranged in the picking mechanism, and the degree of automation of the device is increased by the linkage of the sensor; blocks for limiting the tremella planting pot and a material-blocking cylinder 26 for driving the lifting of the tremella planting pot are arranged between adjacent picking mechanisms.

[0042] In the embodiment of the present invention, the Tremella fuciformis planting pots 38 are arranged in an array in the Tremella fuciformis planting pot, and the front and rear plates are extended longitudinally, and the multiple groups of picking rods are arranged to facilitate the simultaneous picking of multiple Tremella fuciformis placed side by side to increase work efficiency.

[0043] In an embodiment of the present invention, the conveyor line, branch conveyor line and discharge conveyor line are all composed of a conveying bracket 39, a conveying roller 40, a conveying motor 41 and a synchronous sprocket 42. The conveying rollers are extended at both ends and are rotatably connected to the conveying bracket, and both ends of the conveying rollers are connected and rotate synchronously via synchronous sprockets and synchronous chains. The conveying sprockets are driven by the conveying motor, and the conveying rollers are evenly spaced along the conveying direction. A control box 43 is fixedly provided on the branch conveyor line, and the conveying motor, picking mechanism and material shifting mechanism are all electrically connected to the control box.

[0044] In the embodiment of the present invention, the intersection of the conveyor line and the branch conveyor line, and the intersection of the branch conveyor line and the discharging conveyor line are connected via long conveyor rollers 44, that is, the conveyor rollers between the two fixed frames are long conveyor rollers to facilitate pushing the tremella planting pots on the conveyor line to the branch conveyor line, or pushing the tremella planting pots on the branch conveyor line along the long conveyor rollers to the discharging conveyor line. The blocking cylinder at the intersection of the conveyor line and the branch conveyor line is located on the conveyor line, and the blocking cylinder is also arranged at the intersection of the branch conveyor line and the discharging conveyor line, but is arranged at the end of the branch conveyor line to block the tremella planting pots that have been picked, and the corresponding two sets of material shifting mechanisms are symmetrically arranged.

[0045] In an embodiment of the present invention, the picking mechanism also includes a pressing mechanism for crimping the tremella planting pot, the pressing mechanism includes a planting pot pressing rod 46 arranged in the same direction as the conveying direction of the conveying roller, the planting pot pressing rod is located above the branch conveyor line and is driven by a pressing cylinder 47 to move vertically, and both ends of the planting pot pressing rod are tapered to guide the tremella planting pots arranged in an array in the tremella planting pot.

[0046] The working method of the Tremella picking device is carried out in the following steps:

[0047] Diverting conveying: First, place the Tremella fuciformis planting pots on the conveyor line for conveying. The sensor senses that there are no Tremella fuciformis planting pots at the junction of the branch conveyor line and the conveyor line. The blocking cylinder extends the block upward to block the Tremella fuciformis planting pots. Then, the cylinder is contracted to drive the Tremella fuciformis planting pots to slide along the long conveyor roller until they slide to the branch conveyor line and stop.

[0048] At this time, the material blocking cylinder is reset, and the conveyor line continues to convey normally. The Tremella fuciformis planting pots continue to be conveyed along the branch conveyor line. When the sensor cannot sense the Tremella fuciformis planting pots again, the material blocking cylinder is activated again. This cycle is repeated, and multiple groups of branch conveyor lines are used to divert the materials to the picking mechanism for orderly picking to avoid accumulation that affects work efficiency.

[0049] Clamping and picking: First, each cylinder is reset, that is, the reset cylinder, transverse cylinder, swing cylinder, picking cylinder, and material blocking cylinder are all in a retracted state, and the lifting cylinder and the giving way cylinder are in an extended state. When the tremella planting pot is transported to the picking station via the branch conveyor line, the material blocking cylinder of the picking mechanism is extended, and the tremella planting pot is blocked by the material blocking. At this time, the swing cylinder extends to drive the rotating rod to rotate, driving the front splint to swing close to the tremella, and the transverse cylinder extends to push the rear splint close to the tremella. At the same time, the giving way cylinder contracts, driving the rear splint to move upward, which is manifested as the rear splint moving obliquely upward toward the direction of the tremella and the front splint swinging to clamp the tremella. After clamping, the picking rod is extended through the picking cylinder to drive the shovel to the bottom of the tremella to complete the picking.

[0050] Tremella collection: The picking rod is supported at the bottom of the tremella, the lifting cylinder resets and contracts, driving the connecting plate to lift as a whole, that is, the tremella is lifted, and then the reset cylinder extends out to slide the support plate along the horizontal slide rail to send the tremella to the top of the longitudinal conveyor belt. The picking cylinder, horizontal cylinder, give way cylinder and swing cylinder are all reset to make the tremella out of the clamping and supporting state, and freely fall to the longitudinal conveyor belt to be transported and discharged to the receiving box. At this time, the reset cylinder resets and contracts again to move the support plate horizontally to the top of the conveyor roller to wait for the next tremella planting pot. At the same time, the material blocking cylinder contracts to release the tremella planting pot that has been picked, and this cycle is repeated.

[0051] Collection of Tremella fuciformis planting pots: After the Tremella fuciformis planting pots pass through the last picking mechanism, they are transported to the end along the branch conveyor line, blocked by the blocking cylinder, and pushed to the discharging conveyor line through the material shifting mechanism for collection and discharging.

[0052] The present invention is not limited to the above-mentioned best embodiment, and anyone can derive other various forms of Tremella picking devices and working methods thereof under the enlightenment of the present invention.

A working method of a Tremella picking device, characterized in that: A tremella picking device as described in any one of claims 1 to 9 is adopted, and the following steps are followed: first, the tremella planting pots are placed on the conveyor line for transportation, and the sensor senses that there are no tremella planting pots stacked at the junction of the branch conveyor line and the conveyor line, and the blocking cylinder extends the block upward to block the tremella planting pots, and then the toggle cylinder is contracted to drive the tremella planting pots to slide along the long conveyor roller until they slide to the branch conveyor line and stop; when the tremella planting pots are transported to the picking station via the branch conveyor line, the blocking cylinder of the picking mechanism is extended, and the tremella planting pots are blocked by the blocking material, and at this time, the swing cylinder is extended to drive the rotating rod to rotate, driving the front splint to swing close to the tremella, and the transverse cylinder is extended to push the rear splint close to the tremella, and at the same time, the yield cylinder is contracted to drive the rear splint to move upward, which is embodied as the rear The splint moves obliquely upward toward the direction of the white fungus and clamps the white fungus with the front splint. After clamping, the picking rod is extended through the picking cylinder to drive the shovel to the bottom of the white fungus to complete the picking. The rear picking rod is supported and connected to the bottom of the white fungus, and the lifting cylinder resets and contracts, driving the connecting plate to lift as a whole, that is, the white fungus is lifted, and the rear reset cylinder extends to slide the support plate along the horizontal slide rail to send the white fungus to the top of the longitudinal conveyor belt. The picking cylinder, horizontal cylinder, give way cylinder and swing cylinder are all reset, so that the white fungus is out of the clamping and supporting state, and falls freely to the longitudinal conveyor belt to be transported and discharged into the receiving box. At this time, the reset cylinder resets and contracts again to move the support plate horizontally to the top of the conveyor roller to wait for the next white fungus planting pot. At the same time, the blocking cylinder contracts to release the white fungus planting pot that has been picked, and this cycle is repeated.
