Description

Technical Field

[0001] The present invention relates to the technical field of automatic picking of Agaricus bisporus, and in particular to a control method for assisting mushroom collection. Background Art

[0002] Agaricus bisporus is a common edible fungus. It has extremely high nutritional and medicinal value and can be processed into various foods, health products, and even medicines. It has considerable economic value.

[0003] Agaricus bisporus cultivation has achieved large-scale factory production. Factory-grown mushroom houses are not restricted by seasons, allowing for daily fruiting and year-round production, resulting in high yields and profitable returns. Factory-grown mushroom houses are typically 20-30 meters long, 6-10 meters wide, and 5-6 meters high. They can be equipped with two to four rows of multi-layered beds running the length of the house. These beds are typically made of metal structural profiles, 1-1.6 meters wide, with five to six layers, and 50-70 centimeters between them. The lowest bed is approximately 30 centimeters from the ground, while the highest is at least 1 meter from the roof. Passageways between the beds are 80-100 centimeters wide, and the passageways between the beds and the walls are 40-80 centimeters wide.

Furthermore, Agaricus bisporus has the biological characteristics of uneven size and 24-hour growth, which places high demands on labor picking skills and working hours. The high labor costs faced by Agaricus bisporus cultivation factories are becoming increasingly serious. Automatic picking and harvesting by automated picking robots can save manpower, improve efficiency, and reduce costs. For information on the structure and working method of the automatic picking robot, please refer to the invention application with publication number CN 113940239 A, entitled "Intelligent Picking System," and the utility model patent with authorization publication number "CN217372374U," entitled "A Mobile Agaricus Bisporus Picking Robot."

[0005] However, the existing automatic picking robots and collection devices have the following technical defects during operation: (1) Since the mushroom storage baskets filled with mushrooms are distributed circumferentially on the circulation chain, after the automatic picking robot completes the collection of mushrooms on the multi-layer bed frame, it is necessary to manually replace the mushroom storage baskets one by one, that is, to remove the mushroom storage baskets filled with mushrooms, dump the mushrooms and then put them back on the corresponding tray, resulting in low collection efficiency and a small collection quantity; (2) The roots of the mushrooms cut by the automatic picking robot fall directly on the ground of the mushroom house and are not effectively collected. They need to be manually cleaned, resulting in the automation level of the entire picking system needs to be improved. Summary of the Invention

[0052] The present application will be further described in detail below with reference to the accompanying drawings using specific embodiments.

[0053] The specific embodiments described below are merely preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto. Those skilled in the art may make some modifications or variations based on or in accordance with the principles, concepts, and spirit of the present application, and the technical solutions formed by such modifications or variations shall be included within the scope of protection of the present application.

[0054] like Figure 1As shown, the present invention provides a mushroom harvesting robot system, including an automatic picking robot 100 and an automatic collecting device 200. Figure 2-Figure 6As shown, the automatic picking robot 100 includes a base 101, a walking mechanism 102, a picking actuator 103, an X-axis moving mechanism 104, a Y-axis moving mechanism 105, a conveying device and a root cutting device. The base 101, walking mechanism 102, picking actuator 103, X-axis moving mechanism 104 and Y-axis moving mechanism 105 of the above-mentioned automatic picking robot 100 are basically the same as the base 101, walking mechanism 102, picking actuator 103, first X-axis mounting plate, second X-axis mounting plate, first Y-axis mounting plate, second Y-axis mounting plate and the drive component structure on each mounting plate in the authorization announcement number CN113940239B, which is named as the intelligent picking system. The conveying device includes a base plate 106, a conveying drive motor 107, an active conveying roller 108, a driven conveying roller 109, a conveyor belt 110, and a soft brush rib 111. The conveying drive motor 107 is fixed to the proximal end of the base plate 106, the active conveying roller 108 is connected to the output end of the conveying drive motor 107, and the driven conveying roller 109 is rotatably mounted on the distal end of the base plate 106. The conveyor belt 110 is connected to the active conveying roller 108 and the driven conveying roller 109. The conveying drive motor 107 operates through the active conveying roller 108 and the driven conveying roller 109 to operate the conveyor belt 110. The conveyor belt 110 consists of two parts: a first conveying portion 11001 and a second conveying portion 11002. The second conveying portion 11002 is used to convey mushroom roots, and the first conveying portion 11001 is used to convey mushrooms (caps). The soft brush ribs 111 are fixedly mounted on the base plate 106. Three soft brush ribs 111 are arranged side by side: the first soft brush rib 111 is located outside the first conveying portion 11001, the second soft brush rib 111 is located between the first conveying portion 11001 and the second conveying portion 11002, and the third soft brush rib 111 is located outside the second conveying portion 11002. A groove 10602 is formed between the second and third soft brush ribs 111, and a groove 10601 is formed between the first and second soft brush ribs 111. A discharge port 10603 is provided on the base 101 at the distal end of the base plate 106. The soft brush retaining edge 111 forms a retaining surface with a certain blocking force. When the mushrooms picked by the picking actuator 103 move along the Y-axis direction driven by the Y-axis moving mechanism 105, they can pass through the soft brush retaining edge 111.The number of the root cutting connection seat 112, the forward driving motor 113, the driving gear 114, the driven rack 115, the electric finger gripper 116 and the scissor blade 117 is the same as the number of the Y-axis mounting plates in the Y-axis moving mechanism 105. In this solution, the basic mechanism of the automatic picking robot 100 in CN113940239B is adopted. The Y-axis moving mechanism 105 includes a first Y-axis mounting plate and a second Y-axis rotating plate. Therefore, the two root cutting connection seats 112 are respectively fixed to the corresponding first Y-axis mounting plate and the second Y-axis mounting plate near the groove 1. Below one side of 0602, a linear slide 118 is fixed to the bottom of the root cutting connection base 112. A driven rack 115 engages with the linear slide 118 via a forward slider 119. A forward drive motor 113 is fixed above the root cutting connection base 112. The output end of the forward drive motor 113 is connected to a drive gear 114 that meshes with the driven rack 115. An electric finger clamp 116 is fixed to the bottom surface of the driven rack 115. Two scissor blades 117 are fixed to the two jaws of the electric finger clamp 116 and are arranged toward the side of the groove 10602. The root cutting connection base 112, forward drive motor 113, drive gear 114, driven rack 115, electric finger clamp 116, scissor blades 117, linear slide 118, and forward slider 119 constitute the root cutting device, which has two sets. The picking actuator 103 moves with the Y-axis moving mechanism 105 and the X-axis moving mechanism 104, moving the picked mushrooms to the slot 10602, and the forward drive motor 113 drives the driven rack 115 and the electric finger clamp 116 in the open state to move until the front of the two scissor blades 117 reaches the mushroom root (the mushroom root is located between the two scissor blades 117), and the electric finger clamp 116 drives the two scissor blades 117 to close, and the root of the mushroom is cut off and falls onto the second conveying part 11002. In order to sense the moving position of the driven rack 115 and thereby more accurately control the forward and backward positions of the electric finger clamp 116, the first position and second position of the root cutting connecting seat 112 are respectively connected to the first proximity switch 120 and the second proximity switch 121, and the driven rack 115 is provided with a sensing block 122 for cooperating with the first proximity switch 120 and the second proximity switch 121 for sensing.

[0055] like Figure 5As shown, a suction cup cleaning component is also provided in the base 101, and the suction cup cleaning component includes a suction cup cleaning tank 123, a brush plate 124, a cleaning motor 125, a water collecting tank 126, a water inlet pump 127 and a drainage pump 128, wherein the number of the suction cup cleaning tank 123, the brush plate 124, the cleaning motor 125, the water inlet pump 127 and the drainage pump 128 is the same as the number of the picking actuator 103. In this scheme, the automatic picking robot 100 basic structure in CN113940239B is adopted, and there are two groups of picking actuators 103, so the suction cup cleaning tank 123, the brush plate 124, the cleaning motor 125, the water inlet pump 127 and the drainage pump 128 are 127 and the drainage pump 128 are selected as two sets and are respectively installed on both sides of the central axis of the base 101.

After the picking actuator 103 has performed the picking task for a long time, other foreign matter such as mushroom residue, fine particles of culture soil, etc. may adhere to the surface of the suction cup. In order to ensure a good subsequent adsorption effect, with the cooperation of the Y-axis moving mechanism 105 and the X-axis moving mechanism 104, the picking actuator 103 is driven to move to the top of the corresponding suction cup cleaning groove 123, and the water inlet pump 127 supplies water to the suction cup cleaning groove, driving the picking actuator 103 to move so that the suction cup moves down a distance and is immersed in the water in the suction cup cleaning groove 123. At this time, the bristles of the brush plate 124 contact the surface of the suction cup, and then the cleaning motor 125 works to drive the brush plate 124 to rotate to clean the suction cup. After cleaning, the picking actuator 103 is activated, the suction cup is raised, and the drainage pump 128 drains water.

The rotating motor 307 is in motion, driving the auxiliary rail 306 to switch between a vertical state and a horizontal state. When the auxiliary rail 306 is in a horizontal state, it is used to dock the rails of the robot transfer rack 302 and the robot storage rack 301, and the rails of the robot transfer rack 302 and the multi-layer bed frame 300. When the auxiliary rail 306 is in a vertical state, it does not affect the layer-changing operation of the automatic picking robot 100 on the multi-layer bed frame 300 by means of the transfer forklift 500.

[0075] The main working process of the mushroom harvesting robot system of the present invention is described below:

[0076] The external power source energizes the busbar 236 .

[0077] The robot transfer frame 302 is transported to the side of the robot storage frame 301 by the transfer forklift 500, the rotating motor 307 drives the auxiliary rail 306 to rotate to the horizontal, the auxiliary rail 306 docks with the rail in the robot storage frame 301, and the automatic picking robot 100 moves into the robot transfer frame 302, the electric push rod 304 extends, and the top pressure block 305 presses the action mechanism of the automatic picking robot 100. Under the control of the external controller, the transfer forklift 500 runs to the outside of the first layer of the multi-layer bed frame 300 where mushrooms need to be picked, the auxiliary rail 306 docks with the slide 300-1 in the multi-layer bed frame 300, the electric push rod 304 contracts, and the automatic picking robot 100 moves into the multi-layer bed frame 300.

[0078] After the automatic picking robot 100 completely enters the multi-layer bed frame 300, the first displacement mechanism drives the carbon brush 237 to contact the sliding contact line 236, and the external power supply supplies power to the material basket delivery device, the material basket transmission device and the material receiving and feeding device. The second displacement mechanism corresponding to the first layer drives the conductive contact 243 to contact the power input port of the automatic picking robot 100, and the external power supply supplies power to the automatic picking robot 100. The first transport body and the automatic picking robot 100 move forward / stop synchronously.

[0079] The automatic picking robot 100 stays at a certain position for a period of time, and the picking actuator 103 performs the picking operation. The picking actuator 103 of the automatic picking robot 100 moves the picked mushrooms to the top of the second conveying part 11002 of the mushrooms, and the forward driving motor 113 drives the electric finger gripper 116 to move forward. The electric finger gripper 116 moves, and the scissor blade 117 completes the cutting of the mushroom roots. The picking actuator 103 then moves the mushrooms (caps) without the mushroom roots to the top of the first conveying part 11001, and then the suction cup of the picking actuator 103 releases the mushrooms. The first conveying part 11001 and the second conveying part 11002 of the conveyor belt 110 respectively transfer the mushrooms and mushroom roots to the discharge port 10603. At the same time, the left clamping plate 209 and the right clamping plate 209 are used to hold the mushrooms. The stacked material basket group 400 clamped by the plate 210 is moved down to a row of driven rollers 257 of the front frame 205 under the drive of the first lifting mechanism 206, and the positioning clamping drive motor 261 drives the front clamping plate 264 and the rear clamping plate 265 to approach until the clamping of the bottom material basket (the penultimate material basket) in the stacked material basket group 400 is completed. Next, the left clamping plate 209 and the right clamping plate 210 clamp the remaining material baskets again and move upward. The penultimate material basket remains on a row of driven rollers 257. Next, driven by the rotating roller drive motor, the penultimate material basket located on the driven roller 257 moves to the second material receiving area 22402 as the front material basket. Repeat the above-mentioned material basket placing operation and move the next material basket (the second to last material basket of the stacked material basket group 400) to the first material receiving area 22401 as the rear material basket. The lifting cylinder in the corresponding material receiving area lifts up the left conveyor belt transmission mechanism 280 and the right conveyor belt transmission mechanism 281 to support the above-mentioned corresponding rear material basket and front material basket. The mushrooms transported from the discharge port 10603 to the first-floor inclined plate 225 fall into the rear material basket through the first channel 22501, and the mushroom roots fall into the front material basket through the second channel 22502. The weighing sensor 276 detects that the collected weight meets the specified requirements, and the synchronous drive motor 278 drives the material basket to be transported to the corresponding first conveyor belt mechanism 251 and the second conveyor belt mechanism 252. Then the second transport body moves to the work station at the end of the second track, and the worker receives the fully loaded material basket transported by the conveyor belt mechanism. Finally, the second transport body returns to the side of the first transport body to continue the next round of material collection.

[0080] When performing the layer-changing operation, the first transport vehicle body returns to its initial position, the automatic picking robot 100 moves into the robot transfer frame 302, the rotating motor 307 drives the auxiliary rail 306 to rotate to vertical, the transfer forklift 500 lifts the robot transfer frame 302 to align with the second layer of the multi-layer bed frame 300, the rotating motor 307 drives the auxiliary rail 306 to rotate to horizontal, the automatic picking robot 100 enters the multi-layer support to pick, and the mushrooms are transported from the discharge port 10603 to the upper ramp plate 229. The mushrooms fall into the mushroom holding box 227 through the main channel 22901, and the mushroom roots fall into the root collecting hopper 228 through the channel 22902. The mushroom roots in the root collecting hopper 228 fall into the front material basket through the discharge pipe 234. After collecting for a period of time, the mushroom holding box 227 moves downward with the flow synchronous belt 233. The mushroom holding box 227 located above reaches the second-level position to continue collecting. The mushroom holding box 227 full of mushrooms moves to the lower end of the flow synchronous belt 233 and turns over, and the mushrooms are dumped into the rear material basket.

[0081] When the material baskets in the front frame 205 are used up, the second transport body moves to the workstation at the end of the second track, and the worker places the new stacked material basket group on the first conveyor belt mechanism 251. The second transport body returns to the side of the first transport body, and the first conveyor belt mechanism 251 transmits the new stacked material basket group along the left conveyor belt transmission mechanism 280 and the right conveyor belt transmission mechanism 281 in the first material receiving area 22401 to the top of a row of driven rollers 257 in the main frame 224, and then the left conveyor belt transmission mechanism 280 and the right conveyor belt transmission mechanism 281 are used up. The structure 281 descends, and the new stacked material basket group is pressed on a row of driven rollers 257 in the main frame 224. Then the row of driven rollers 257 in the main frame 224 rotates to move the new stacked material basket group into the front frame 205. The new stacked material basket group is pressed on a row of driven rollers 257 in the front frame 205. Under the joint action of the side push plate 2, the front baffle 6 and the rear baffle 7, the new stacked material basket group is centered below the left clamping plate 209 and the right clamping plate 210, and the subsequent material basket delivery operation is continued.

[0082] It can be seen that the entire process does not require manual replacement of the material baskets one by one, and the automated operation of the material basket placement is realized. Its automation level is higher than that of the existing technology, the operating efficiency is further improved, and mushrooms and mushroom roots can be collected synchronously to meet higher intelligent operation requirements.
