Description

Technical Field

[0001] The present invention relates to the technical field of automatic picking of Agaricus bisporus, and in particular to a transport device capable of transporting mushroom baskets. 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.

[0004] Agaricus bisporus cultivation is a labor-intensive industry. In recent years, labor costs have been rising. 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] Since the environment in the factory mushroom house can be controlled automatically or semi-automatically, production is not restricted by seasons, the mushroom yield is high, and the benefits are good.

[0006] 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

[0045] like Figure 14 and Figure 15 As shown, the basket delivery device includes a front frame 205, a first lifting mechanism 206, a first lifting plate 207, an inner frame 208 and an opposing clamping mechanism. The front frame 205 is fixed on the first frame 202, the first lifting mechanism 206 is fixed in the front frame 205 and is connected to the inner frame 208 via the first lifting plate 207. The first lifting mechanism 206 adopts a slide module, the slide module is provided with a slider, the first lifting plate 207 is fixedly connected to the slider, and the front frame 205 is fixed on the frame away from the slide module. There are a front vertical track 20501 and a rear vertical track 20502, and the outer side of the inner frame 208 is rotatably installed with a front roller 20801 that cooperates with the front vertical track 20501 and a rear roller 20802 that cooperates with the rear vertical track 20502; the first lifting mechanism 206 can also specifically adopt a vertical belt transmission method, and the first lifting plate 207 is fixed on the vertical belt through a connecting piece; the first lifting plate 207 rises or falls, driving the inner frame 208 and the opposite clamping mechanism to rise or fall in the front frame 205.

[0046] The opposing clamping mechanism includes a left clamping plate 209, a right clamping plate 210, an opposing clamping drive motor 211, a driving gear 212, a driven gear 213, an active forward and reverse screw 214 and a driven forward and reverse screw 215.

[0047] The basket delivery device can adapt to baskets of different sizes, and the adaptability of the basket delivery device is enhanced. In addition, the process of placing new baskets stacked together into the basket delivery device is convenient and fast.

[0048] like Figure 5-Figure 8As shown, the material receiving and feeding device includes a main frame 224, a first-layer inclined plate 225, a belt frame 226, a mushroom holding box 227, a root collecting hopper 228 and an upper-layer inclined plate 229. The main frame 224 is fixed to one side of the front frame 205 and the main frame 224 is divided into a first material collecting area 22401 and a second material collecting area 22402 along the length direction. The first-layer inclined plate 225 is installed on the inner side of the main frame 224 and tilted toward the first layer of the multi-layer bed frame 300. The first-layer inclined plate 225 is divided into a first channel 22501 corresponding to the first material collecting area 22401 and a second material collecting area 22402 through the first-layer partition. The second channel 22502 corresponding to the material area 22402, the belt frame 226 is fixed to the main frame 224 through the connecting frame, the lower end of the belt frame 226 extends to the first material receiving area 22401 and is rotatably connected to the main pulley 230, the upper end of the belt frame 226 extends to a position higher than the uppermost layer of the multi-layer bed frame 300 and is rotatably connected to the slave pulley 231, and a flow motor 232 for driving the main pulley 230 to rotate is fixed on the main frame 224, the main pulley 230 and the slave pulley 231 are connected through a flow synchronous belt 233, the mushroom accommodating box is provided with an opening, and there are multiple mushroom accommodating boxes 227. The mushroom receiving box 227 is fixed to the circulating synchronous belt 233 via a connecting piece along the circumferential direction, and the mushroom receiving box 227 is flipped with the circulating synchronous belt 233 from the opening set upward on the far side of the belt bracket to the opening set downward on the near side of the belt bracket. There are multiple root receiving hoppers 228, which are fixed to the far side of the belt frame 226 vertically via a transverse rod. The bottom of the root receiving hopper 228 is connected to a discharge pipe 234 set toward the second receiving area 22402. Each discharge pipe 234 is concentrically arranged in the vertical direction. The upper slope plate 229 is installed on the inner side of the root receiving hopper 228 and tilted toward the non-first layer of the corresponding multi-layer bed frame 300. The upper inclined plate 229 is divided into a main channel 22901 corresponding to the opening of the mushroom holding box 227 and a slave channel 22902 corresponding to the opening of the root collecting hopper 228 through the upper partition. When the automatic picking robot 100 completely enters the first layer of the multi-layer bed frame 300, the automatic collecting device 200 is located at the initial position of the first track, and the discharge port of the automatic picking robot 100 corresponds to the channel entrance of the first-layer inclined plate 225. Similarly, when the automatic picking robot 100 is located on other layers of the multi-layer bed frame 300, the discharge port of the automatic picking robot 100 corresponds to the channel entrance of the upper inclined plate 229.

[0049] Each mushroom container 227 is evenly spaced on the circulation synchronous belt 233. The distance between the openings of adjacent mushroom containers 227 is the same as the distance between the openings of adjacent root collection hoppers 228. After the circulation motor 232 drives the circulation synchronous belt 233 to run the above distance, the next mushroom container 227 arrives at the same position as the previous mushroom container. At this time, the mushroom containers 227 and root collection hoppers 228 corresponding to each layer still maintain a one-to-one correspondence, ensuring the smooth progress of layer-changing picking. Figure 13 As shown, an origin sensing sensor 284 is installed on the connecting frame. When the mushroom holding box 227 reaches the sensing position of the origin sensing sensor 284, there is a mushroom holding box 227 at the lower end of the circulation synchronous belt 233 that is flipped and opened downward. The origin sensing sensor 284 sends a sensing signal, and the controller receives the sensing signal and controls the circulation motor 232 to stop for a few seconds. The mushrooms in the mushroom holding box 227 fall steadily into the material basket in the first material receiving area 22401.

[0050] In order to realize the synchronous advancement of the first transport vehicle body and the automatic picking robot, the moving speed of the first walking bottom wheel 203 is controlled to be the same as the moving speed of the walking mechanism 102 of the automatic picking robot 100, and the two move forward and stop synchronously. Figure 9 As shown, the upper end of the belt frame 226 is equipped with a walking top wheel 235 for cooperating with the multi-layer bed frame 300. The walking top wheel 235 is a passive rolling. Specifically, in order to facilitate the cooperation between the walking top wheel 235 and the multi-layer bed frame 300, a third lifting mechanism 23501 is provided between the walking top wheel 235 and the belt frame 226. The third lifting mechanism 23501 can adopt a slide module structure. The walking top wheel 235 is connected to the slider of the third lifting mechanism 23501 through the lifting frame 23502. The first walking bottom wheel 203 at the bottom of the first frame 202 is set on the first guide rail 201. The third lifting mechanism 23501 The top walking wheel 235 is driven to move downward and roll in contact with the upper surface of the multi-layer bed frame 300. In order to increase the tightness between the top walking wheel 235 and the multi-layer bed frame 300, two vertical sliding shafts 23503 arranged side by side are installed at the front end of the lifting frame 23502. A sliding block 23504 is installed on the vertical sliding shaft 23503. Spring parts 23505 are sleeved on the vertical sliding shaft 23503 between the upper surface of the sliding block 23504 and the lifting frame 23502, and on the vertical sliding shaft 23503 between the lower surface of the sliding block 23504 and the lifting frame 23502. The top walking wheel 235 is connected to the sliding block 23504 via the wheel axle.

In the initial state, the first-floor slope plate 225 / upper-floor slope plate 229 are set vertically.

[0052] like Figure 12 and Figure 13As shown, a busbar 236 is arranged on the outside of the first guide rail 201, and the first frame 202 is connected to a carbon brush 237 and a first displacement component that drives the carbon brush 237 to electrically contact the busbar 236. Specifically, the first displacement component includes a second lifting mechanism 238, a second lifting plate 239, a first translation mechanism 240 and a translation plate 241. The second lifting mechanism 238 is fixed on the side of the first frame 202 close to the busbar 236, the first translation mechanism 240 is connected to the second lifting mechanism 238 via the second lifting plate 239, and the upper end of the translation plate 241 is connected to the first translation mechanism 240. The lower end of the translation plate 241 is connected to the carbon brush 237 through the pin 242 and the spring 285. The two pins 242 pass through the lower end of the translation plate 241 respectively. The two pins 242 can slide. The front ends of the two pins 242 are respectively connected to the carbon brush 237. There are two springs 285. The first spring 285 is sleeved on the first pin 242. The front end of the first spring 285 rests on the carbon brush 237, and the rear end of the first spring 285 rests on the lower end of the translation plate 241. Similarly, the second spring is sleeved on the second pin, the front end of the second spring rests on the carbon brush 237, and the rear end of the second spring rests on the lower end of the translation plate 241. The second lifting mechanism 238 and the first translation mechanism 240 adopt the structure of a slide module. The second lifting plate 239 is connected to the slider of the second lifting mechanism 238, and the translation plate 241 is connected to the slider of the first translation mechanism 240.

The bottom of the rear clamping plate 265 is connected to the rear sliders 270 that slide in cooperation with the guide light shaft 263 on both sides. When the positioning and clamping drive motor 261 is working, it drives the front clamping plate 264 and the rear clamping plate 265 to move closer to or away from each other. When the two roller drive motors 255 rotate forward, they drive the two rows of driven rollers 257 to rotate clockwise respectively. The material baskets located in the front frame 205 and pressed on a row of driven rollers 257 are transported one by one to the first material receiving area 22401 and the second material receiving area 22402 of the main frame 224.

The driving structure of the second walking bottom wheel 254 is the same as that of the first transport vehicle body, which is not repeated here. The first conveyor belt mechanism 251 and the second conveyor belt mechanism 252 are installed side by side on the surface of the second frame 250, corresponding to the first material receiving area 22401 and the second material receiving area 22402 respectively.

The light emitted by the reflective photoelectric sensor 283 to the reflective surface of the first frame 202 is reflected back by the reflective surface, so that the reflective photoelectric sensor 283 generates an induction signal, completing the position docking of the second frame 250 and the first frame 202. At this time, the first conveyor belt mechanism 251 / the second conveyor belt mechanism 252 receives the material basket transmitted by the left conveyor belt transmission mechanism 280 and the right conveyor belt transmission mechanism 281 in each corresponding area, and under the forward drive of the second travel motor 253, the second frame 250 is transported along the second track to the collection station, and then the second travel motor 253 is reversely driven to bring the second frame 250 back to the position corresponding to the first frame 202.

[0060] like Figure 16 and Figure 17As shown, a material basket centering assembly is provided in the front frame 205, and the material basket centering assembly includes a second translation mechanism 1, a side push plate 2, a front and rear clamping drive motor 3, a clamping screw 4, a clamping optical axis 5, a front baffle 6 and a rear baffle 7. The second translation mechanism 1 is fixed in the front frame 205, and the side push plate 2 is connected to the second translation mechanism 1 and is arranged toward the proximal end of the horizontal transmission mechanism. Similarly, the second translation mechanism 1 adopts a slide module structure in this solution, and the side push plate 2 is fixed on the slider of the second translation mechanism 1. The two ends of the clamping screw 4 rotate The front and rear clamping drive motors 3 are fixed to the bottom of the front frame 205 and are connected to the middle of the clamping screw 4 through a synchronous belt transmission mechanism. There are two clamping optical axes 5, which are symmetrically installed on both sides of the clamping screw 4. The upper part of the front baffle 6 and the upper part of the rear baffle 7 pass through the gap between the adjacent driven rollers 257 to form a centering part. The length of the centering part extending out of the driven roller 257 is at least higher than the height of a single material basket. The bottom of the front baffle 6 is matched with the orthogonal thread of the clamping screw 4 through the first nut seat 8 and the front baffle is fixed to the bottom of the front frame 205 and is connected to the middle of the clamping screw 4 through a synchronous belt transmission mechanism. The bottom of the plate 6 has a first slider 10 on both sides that slides with the clamping optical axis 5, the bottom of the rear baffle 7 is matched with the anti-thread of the clamping screw 4 through the second nut seat 9, and the bottom of the rear baffle 7 has a second slider 11 on both sides that slides with the clamping optical axis 5. In this solution, there is one basket centering component in the main frame 224 and two positioning clamping components. The basket centering component is located at the center of the area between the left clamping plate 209 and the right clamping plate 210. The two positioning clamping components are symmetrically distributed on both sides of the basket centering component. The conveying belt mechanism 251 / the second conveying belt mechanism 252 transmits the stacked material basket group 400 into the main frame 224, and is transported to the front frame 205 under the reverse drive of the roller drive motor 255. The second translation mechanism 1 drives the side push plate 2 to move to the right, and the front and rear clamping drive motors 3 drive the front baffle 6 and the rear baffle 7 to approach each other, so that the material basket is located directly below the rectangular area formed by the left clamping plate 209, the right clamping plate 210 and the front and rear frames of the inner frame 208, for use by the subsequent material basket delivery device.

[0061] When the basket feeding device is empty (i.e., there is no stacked basket in the front frame 205), the pre-prepared stacked basket is first transported to the main frame 224 through the first conveyor belt mechanism 251 or the second conveyor belt mechanism 252, and then the stacked basket is transported to the front frame 205. In order to push the stacked basket group entering the main frame 224 away from the side of the main frame 224 and prevent the stacked basket group from interfering with the parts in the front frame 205 due to being too close to the frame side plate when entering the front frame 205, such as interfering with the probe 266 on the clamping part of the front clamping plate 264 and the rear clamping plate 265, as shown in FIG. Figure 7 and Figure 19As shown, a basket pushing mechanism is provided in the main frame 224, and the basket pushing mechanism includes a forward pushing drive motor 12, a fixed plate 13, an active rocker arm 14, a driven rocker arm 15 and a forward pushing plate 16. The fixed plate 13 is fixed to the inner side of the main frame 224, and the active rotating shaft 17 and the third driven rotating shaft 20 are installed in parallel on the outer side of the fixed plate 13 through two rear bearing seats, and the second driven rotating shaft 19 and the first driven rotating shaft 18 are installed in parallel on the inner side of the front pushing plate 16 through two front bearing seats (the two front bearing seats are fixedly connected to the inner side of the front pushing plate 16), and one end of the active rocker arm 14 is connected to the inner side of the front pushing plate 16. The active rotating shaft 17 is fixedly connected, the other end of the active rocker arm 14 is fixedly connected to the first driven rotating shaft 18, one end of the driven rocker arm 15 is fixedly connected to the third driven rotating shaft 20, and the other end of the driven rocker arm 15 is fixedly connected to the second driven rotating shaft 19. The front push plate 16, the fixed plate 13, the active rocker arm 14 and the driven rocker arm 15 constitute a parallel four-bar linkage mechanism. The front push drive motor 12 is fixed on the fixed plate 13 and the output shaft of the front push drive motor 12 is connected to the active rotating shaft 17. When the front push drive motor 12 is activated, it drives the front push plate 16 to move forward and backward. It should be noted that as long as the other end of the active rocker arm 14 is rotationally connected to the inner side of the front push plate 16, the other end of the driven rocker arm 15 is rotationally connected to the inner side of the front push plate 16, and one end of the driven rocker arm 15 is rotationally connected to the outer side of the fixed plate 13, it is sufficient. The front push plate 16 is displaced forward a certain distance to push the stacking baskets to a certain position, thereby preventing the stacking baskets from interfering with the probes 266 on the front and rear clamping plates 264 and 265 when entering the front frame 205; or the front push plate 16 is displaced forward to a specified position in advance, and the stacking baskets are transported to the main frame 224 by the first conveyor belt mechanism 251, whereupon they are blocked and limited by the front push plate 16, thereby preventing the stacking baskets from interfering with other parts when entering the front frame 205. In addition, the provision of a basket pushing mechanism allows the material receiving and feeding device to adapt to baskets of different sizes. The front push plate 16 of the basket pushing mechanism is displaced to the desired position, allowing the stacked baskets to be pressed against the front push plate 16 for limiting and positioning, thereby improving the adaptability of the material receiving and feeding device.

[0062] In order to further improve the automation level of the intelligent picking system, and to uniformly store and maintain the automatic picking robot 100, and to improve the complex design of the prior art in which each multi-layer bed frame 300 needs to be equipped with an automatic layer-changing device, the activity space in the mushroom room is liberated, such as Figure 1As shown, the system also includes a robot storage rack 301, a robot transfer rack 302, and a transfer forklift 500 for lifting the robot transfer rack 302. The robot storage rack 301 and the robot transfer rack 302 are provided with a slide 303 that cooperates with the walking mechanism 102 of the automatic picking robot 100. The transfer forklift 500 travels back and forth between the robot storage rack 301 and the multi-layer bed frame 300 where mushroom picking is required. The automatic picking robot 100 completes the transfer mode from the robot storage rack 301-robot transfer rack 302-multi-layer bed frame 300. The transfer forklift 500 raises and lowers the forklift plate on the outside of the multi-layer bed frame 300 to complete the layer changing operation of the automatic picking robot 100 on each multi-layer bed frame 300.

[0063] The main working process of the above-mentioned collection device is described below:

[0064] The external power source energizes the busbar 236 .

[0065] When the automatic picking robot 100 enters the first floor of the multi-layer bed frame 300, Figure 4 As shown, the first displacement component drives the carbon brush 237 to contact the busbar 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 component corresponding to the first layer of the multi-layer bed frame 300 drives the conductive contact 243 to contact the power input port of the automatic picking robot 100 (the carbon brush 237 is electrically connected to the conductive contact 243 through the wire), and the external power supply supplies power to the automatic picking robot 100, and the first transport body and the automatic picking robot 100 move forward / stop synchronously.

[0066] The automatic picking robot 100 stays at a certain position for a period of time, and the picking actuator performs the picking operation. The conveying mechanism of the automatic picking robot 100 transfers the mushrooms and mushroom roots to the discharge port. At the same time, the stacking basket group 400 clamped by the left clamping plate 209 and the right clamping plate 210 is driven by the first lifting mechanism 206 to move down to a row of driven rollers 257 of the front frame 205. The positioning clamping drive motor 261 drives the front clamping plate 264 and the rear clamping plate 265 to move closer until the bottom basket in the stacking basket group 400 is completed. (The penultimate material basket) is clamped, and then the left clamping plate 209 and the right clamping plate 210 clamp the remaining material baskets again (clamp the second to last and third material baskets, at least clamp the second to last material basket) and move up, and the penultimate material basket remains on a row of driven rollers 257. Next, driven by the rotating roller driving 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 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 frame moves to the workstation at the end of the second track, and the worker stands in a fixed position to receive the fully loaded material basket transported by the conveyor belt mechanism. Finally, the second frame returns to the side of the first frame to continue the next round of material collection. The specific process of the second frame returning to the side of the first frame can be that the second frame moves toward the first frame. When the second frame 250 approaches the first frame 202, the light emitted by the reflective photoelectric sensor 283 is reflected back by the reflective surface of the first frame 202, and the reflective photoelectric sensor 283 generates a sensing signal to the controller. At this moment, the controller allows the second frame 250 to continue moving a preset distance, and then the second frame 250 stops moving. The second frame 250 is facing the first frame 202. Figure 11 It should be noted that an infrared reflection type sensor can be used instead of the reflective photoelectric sensor 283. In the case of using an infrared reflection type sensor, there is no need to set a special reflective surface on the first frame 202.

[0067] After the automatic picking robot completes the picking operation on the first layer of the multi-layer bed frame, the layer-changing device changes the layer of the robot and transfers the automatic picking robot to the second layer of the multi-layer bed frame 300. During the picking operation on the second layer, the mushrooms and mushroom roots output from the discharge port slide onto the upper slope plate 229, and the mushrooms slide into the mushroom holding box 227 through the main channel 22901 (refer to Figure 7 As shown), the mushroom roots slide from the channel 22902 into the root collecting hopper 228, and 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 down with the flow synchronous belt 233, and the mushroom holding box located above reaches the second-layer position to continue collecting. The mushroom holding box that has collected 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.

[0068] When the baskets in the front frame 205 are used up, the second frame moves to the workstation at the end of the second track, and the worker places a new stacked basket group on the first conveyor belt mechanism 251. The second frame returns to the side of the first frame, and the first conveyor belt mechanism 251 transmits the new stacked 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. 1 descends, and the newly 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 newly stacked material basket group into the front frame 205. The newly stacked material basket group is pressed on the 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 newly 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.

[0069] 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.
