Description

Technical Field

[0001] This invention relates to the field of bok choy harvesting technology, and in particular to an integrated machine for harvesting and rinsing bok choy. Background Technology

[0002] Chinese cabbage is a vegetable that is extremely rich in minerals and vitamins. It contains more calcium, vitamins, and carotene than Chinese cabbage. Therefore, Chinese cabbage is one of the most commonly consumed vegetables in China. When harvesting Chinese cabbage, it is generally necessary to pull it directly from the ground and clean its roots. In order to facilitate the harvesting and washing work, a small Chinese cabbage harvesting and washing machine is needed.

[0003] In existing technologies, the harvesting and cleaning of bok choy are generally carried out separately. Therefore, additional transfer steps are required during the harvesting and cleaning process. In addition, manual harvesting is time-consuming and labor-intensive, while machine harvesting can damage the bok choy due to the close adhesion between the roots and the soil.

[0063] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0064] (1) The present invention, through the setting of a picking component, a conveying component, an air supply component and a rinsing component, can realize the loosening of soil and picking of small green vegetables by the picking component, and then convey the small green vegetables to the rinsing component by the conveying component for rinsing. During the operation of the conveying component, high pressure gas is generated, which is used to blow the small green vegetables and perform preliminary cleaning of the soil on the roots of the small green vegetables. In addition, the high pressure gas is also used to supply water pressure to the rinsing component for secondary cleaning of the small green vegetables.

[0065] (2) The present invention, through the electric push rod, plate, strong magnet and sealing assembly, can realize that after the rinsing of the small green vegetables is completed, the switch of the electric push rod is turned on. When the electric push rod is working, it drives the plate to move, which in turn causes the strong magnet on the plate to move to the position above the electromagnet. Through the repulsive force between the strong magnet and the electromagnet, the electromagnet descends, which in turn drives the sealing block to descend through the sleeve rod, compressing the spring. After the sealing block descends, the water above the partition enters the area below the partition through the through hole. After the plate moves to the upper surface of the mesh plate, the small green vegetables follow the rotation of the mesh plate, which allows the small green vegetables to move along the surface of the plate to the guide plate, and then enter the box through the guide plate.

[0085] The following is combined Figures 1 to 11 As shown, this embodiment of the invention provides a combined machine for picking and rinsing bok choy, comprising:

[0086] The top of the trolley 1 is arranged in a linear sequence of a storage component, a cleaning component, a conveying component, and a picking component. The picking component is used to pick the small green vegetables, and the conveying component is used to transport the picked small green vegetables to the cleaning component.

[0087] The cleaning components include:

[0088] Water tank 11 is fixed to the top of trolley 1, and a mesh plate 14 is rotatably installed inside water tank 11.

[0089] The plate 23 is hinged to the side wall of the water tank 11, and the bottom of the plate 23 is flush with the top of the mesh plate 14.

[0090] A flushing assembly is installed on the side wall of water tank 11;

[0091] The partition 45 is fixed inside the water tank 11 and is located below the mesh plate 14.

[0092] Through hole 48 is provided on one side of the top of partition 45;

[0093] A sealing assembly is located at the bottom of the water tank 11. The sealing assembly is used to seal the through hole 48. The sealing assembly and the plate 23 form a transmission engagement.

[0094] The conveying components also include:

[0095] A blowing assembly is installed on the top of the trolley 1 and is used to blow away the soil from the roots of the bok choy.

[0096] An air supply component is installed on the top of the trolley 1, and the air supply component and the conveying component form a transmission connection. The air supply component is connected to the bottom of the water tank 11, and the air supply component is connected to the purging component.

[0097] The picking component loosens the soil and picks the bok choy, and then the conveying component transports the bok choy to the washing component for rinsing.

[0098] During the operation of the conveying component, high-pressure gas is generated. This high-pressure gas is used to blow and sweep the bok choy, and to perform preliminary cleaning of the soil on the roots of the bok choy. In addition, the high-pressure gas is also used to pressurize the water supply of the cleaning component, and to perform a secondary cleaning of the bok choy.

[0099] Furthermore, the storage components include:

[0100] Box 19, which is fixed to the side wall of trolley 1;

[0101] Guide plate 20, one end of which is fixed to the side wall of water tank 11 and is located near plate 23, and the other end of guide plate 20 is inside tank 19.

[0102] Furthermore, the cleaning components also include:

[0103] Multiple first nozzles 13 are all installed through the side wall of the water tank 11;

[0104] An annular pipe 12 is connected to multiple first nozzles 13;

[0105] Hollow shaft 43 is rotatably mounted at the bottom of water tank 11 and passes through the bottom of trolley 1, and is fixed to mesh plate 14;

[0106] The third motor 31 is fixed to the bottom of the trolley 1, and the output shaft of the third motor 31 is fixed to the hollow shaft 43;

[0107] Multiple rods 44 are fixed on the hollow shaft 43, and all of the rods 44 are located below the partition plate 45;

[0108] Multiple mounting holes are provided on the side wall of the hollow shaft 43, and each mounting hole is located below the partition plate 45. A filter screen 47 is fixed in each mounting hole.

[0109] A connecting pipe 46 is provided through the top of the hollow shaft 43, and the connecting pipe 46 and the hollow shaft 43 are rotatably connected. The connecting pipe 46 is connected to the annular pipe 12.

[0110] When gas enters the bottom space of the water tank 11, the air pressure in the space below the partition 45 in the water tank 11 rises, causing the water below the partition 45 in the water tank 11 to be forced into the hollow shaft 43. During this process, the sewage is filtered through the filter screen 47, thereby realizing the recycling of water resources to facilitate the subsequent rinsing of the bok choy.

[0111] Furthermore, the sealing assembly includes:

[0112] Sleeve 52 is fixed to the bottom of water tank 11, and sleeve rod 50 is slidably provided inside sleeve 52;

[0113] Spring 53, one end of spring 53 is fixed to the bottom of sleeve 52, and the other end of spring 53 is fixed to sleeve rod 50;

[0114] Sealing block 51 is fixedly sleeved on sleeve rod 50 and is used to seal through hole 48.

[0115] Electromagnet 49 is fixed to the top of sleeve rod 50.

[0116] Furthermore, it also includes:

[0117] A fixed rod 22 is fixed to the top of the trolley 1. A connecting block 30 is rotatably mounted on the fixed rod 22. An electric push rod 21 is mounted on one side of the connecting block 30, and the telescopic end of the electric push rod 21 is rotatably connected to the plate 23.

[0118] Strong magnet 54 is fixed to the bottom of plate 23.

[0119] After the bok choy is rinsed, the switch of the electric push rod 21 is turned on. When the electric push rod 21 is working, it drives the plate 23 to move, which in turn moves the strong magnet 54 on the plate 23 to above the electromagnet 49. Through the repulsive force between the strong magnet 54 and the electromagnet 49, the electromagnet 49 is lowered, which in turn drives the sealing block 51 to lower through the sleeve rod 50, compressing the spring 53. After the sealing block 51 is lowered, the water above the partition 45 enters the area below the partition 45 through the through hole 48. After the plate 23 moves to the upper surface of the mesh plate 14, the bok choy follows the rotation of the mesh plate 14, which allows the bok choy to move along the surface of the plate 23 to the guide plate 20, and then enter the box 19 through the guide plate 20.

[0120] Furthermore, the conveying components include:

[0121] Two first fixing frames 15 are fixed to the water tank 11, and the same first rotating shaft is rotatably provided on the side wall of the two first fixing frames 15.

[0122] Two second fixed frames 24 are fixed to the top of the trolley 1. The side walls of the two second fixed frames 24 are rotatably provided with the same second rotating shaft. The same second conveyor belt 16 is sleeved on the first rotating shaft and the second rotating shaft.

[0123] The second motor 25 is fixed on one of the second mounting brackets 24, and the output shaft and the second rotating shaft of the second motor 25 are fixed.

[0124] Furthermore, the gas supply components include:

[0125] Cylinder 18, cylinder 18 is fixed on trolley 1;

[0126] Piston 42 is slidably disposed inside cylinder 18;

[0127] Transmission rod 39 is fixed to the side wall of piston 42;

[0128] Turntable 41 is rotatably mounted on another second fixed frame 24. A connecting rod 40 is rotatably mounted at the eccentric part of turntable 41, and the connecting rod 40 is rotatably connected to the transmission rod 39.

[0129] The first one-way valve 36 is disposed through the end of the cylinder 18;

[0130] The second one-way valve 37 is installed through the end of the cylinder 18. An air supply pipe 38 is connected to the second one-way valve 37. One end of the air supply pipe 38 passes through the water tank 11 and is located below the partition plate 45.

[0131] When the second motor 25 is working, it drives the second rotating shaft to rotate, which in turn causes the second conveyor belt 16 to work, transporting the bok choy on the second conveyor belt 16 to the water tank 11. At the same time, the second motor 25 drives the turntable 41 to rotate, which in turn drives the piston 42 to move back and forth in the cylinder 18 through the connecting rod 40 and the transmission rod 39, so that the volume of the space enclosed by the piston 42 and the cylinder 18 increases and decreases periodically. During the process of the volume of the space increasing, the outside gas enters the space through the first one-way valve 36. Conversely, when the volume of the space decreases, the gas in the space enters the air supply pipe 38 through the second one-way valve 37. Some of the gas in the air supply pipe 38 enters the two connecting seats 26 and is then output through the second nozzle 27. The airflow output by the second nozzle 27 blows away the soil on the roots of the bok choy, realizing the initial cleaning of the bok choy.

[0132] Furthermore, the purging components include:

[0133] Two brackets 17 are installed on the top of the trolley 1. Each bracket 17 is equipped with a connecting seat 26. Multiple second nozzles 27 are installed through each connecting seat 26. The air supply pipe 38 is connected to both connecting seats 26.

[0134] Furthermore, the harvesting components include:

[0135] Cylinder 32 is fixed to the top of the trolley 1.

[0136] Connecting bracket 10, which is fixed to the telescopic end of cylinder 32;

[0137] Feeding plate 28 is inclinedly fixed to the top of connecting frame 10, and a rotating plate 29 is rotatably provided on one side of the top of feeding plate 28.

[0138] Two fixing blocks 2 are fixed to the side wall of the trolley 1;

[0139] The bidirectional lead screw 3 is rotatably mounted on two fixed blocks 2.

[0140] The first motor 6 is fixed on one of the fixing blocks 2, and the output shaft and the bidirectional lead screw 3 of the first motor 6 are fixed.

[0141] Two sliders 5 are slidably mounted on the side wall of the trolley 1. Each slider 5 has a picking unit slidably mounted on its side wall, and both picking units are fixed to the connecting frame 10.

[0142] Furthermore, the picking unit includes:

[0143] Connecting seat 4 and slider 5 are slidably connected, and connecting seat 4 and connecting bracket 10 are fixed;

[0144] The ripper 7 is rotatably mounted on the side wall of the connecting seat 4, and the side wall of the ripper 7 is provided with multiple shovel heads.

[0145] A connecting plate 35 is fixed to the bottom of the slider 5. A fourth motor 34 is fixed to the bottom of the connecting plate 35, and the output shaft of the fourth motor 34 is fixed to the tumbler wheel 7.

[0146] A fixed plate 8 is fixed to a connecting seat 4. Two connecting shafts are provided on the fixed plate 8, and a first conveyor belt 9 is sleeved on the two connecting shafts.

[0147] Two drive wheels are provided. One drive wheel is fixedly mounted on the output shaft of the fourth motor 34, and the other drive wheel is rotatably mounted on the side wall of the fixed plate 8. The drive wheel is fixed to the nearest connecting shaft, and the same drive belt 33 is mounted on both drive wheels.

[0148] When the switch of cylinder 32 is turned on, cylinder 32 drives the connecting frame 10 to descend. Through the sliding between the connecting seat 4 and the slider 5, the loosening wheel 7 on the connecting seat 4 descends. At this time, the two fourth motors 34 drive the two loosening wheels 7 to rotate in opposite directions. During the rotation of the loosening wheel 7, the soil on both sides of the bok choy is pushed away through the opening of the shovel head on the loosening wheel 7, so that the roots of the bok choy are in a relatively loose state with the soil. During this process, the switch of the first motor 6 is turned on. When the first motor 6 is working, it drives the double-acting screw 3 to rotate, and then the double-acting screw 3 drives the two sliders 5 to move closer to each other, so that the two loosening wheels 7 gradually approach the bok choy. After the loosening wheels 7 approach the bok choy, the rotation directions of the two fourth motors 34 are reversed, so that the two loosening wheels 7 can drive the shovel head to rotate in the opposite direction. With the back of the shovel head, the bok choy is transported upward, that is, the bok choy is pulled out of the ground.

[0149] The specific working method is as follows: When in use, move the trolley 1 to a suitable position so that the bok choy is between the two loosening wheels 7. Turn on the switch of the cylinder 32. When the cylinder 32 is working, it drives the connecting frame 10 to descend. Through the sliding between the connecting seat 4 and the slider 5, the loosening wheel 7 on the connecting seat 4 descends. At this time, the two fourth motors 34 drive the two loosening wheels 7 to rotate in opposite directions. During the rotation of the loosening wheels 7, the soil on both sides of the bok choy is pushed away through the opening of the shovel head on the loosening wheel 7 so that the roots of the bok choy are in a relatively loose state with the soil. During this process, turn on the switch of the first motor 6. When the first motor 6 is working, it drives the double-acting screw 3 to rotate. Then, through the double-acting screw 3, it drives the two sliders 5 to move closer to each other, so that the two loosening wheels 7 gradually approach the bok choy. After the loosening wheels 7 approach the bok choy, the rotation directions of the two fourth motors 34 are reversed, so that the two loosening wheels 7 can drive the shovel head to rotate in the opposite direction. With the back of the shovel head, the bok choy is transported upward, that is, the bok choy is pulled out of the soil.

[0150] During the operation of the fourth motor 34, one of the transmission shafts is driven to rotate through two transmission wheels and transmission belt 33, which in turn drives the first conveyor belt 9 to move. The first conveyor belt 9 causes the harvested bok choy to rise. When the bok choy comes into contact with the rotating plate 29, it pushes the rotating plate 29 to rise. After the bok choy leaves the rotating plate 29, since the rotating plate 29 is set above the feeding plate 28, the rotating plate 29 resets under the action of gravity after detaching from the bok choy, and the rotating plate 29 is in a parallel state with the feeding plate 28. When the bok choy detaches from the two first conveyor belts 9, it falls on the rotating plate 29 and then falls onto the second conveyor belt 16 through the rotating plate 29.

[0151] When the switch of the second motor 25 is turned on, the second motor 25 drives the second shaft to rotate, which in turn makes the second conveyor belt 16 work, transporting the small green vegetables on the second conveyor belt 16 to the water tank 11.

[0152] While the second motor 25 is working, it drives the turntable 41 to rotate, which in turn drives the piston 42 to reciprocate within the cylinder 18 through the connecting rod 40 and the transmission rod 39, causing the volume of the space enclosed by the piston 42 and the cylinder 18 to increase and decrease periodically.

[0153] During the process of increasing the volume of the space, external gas enters the space through the first one-way valve 36; conversely, when the volume of the space decreases, the gas in the space enters the gas supply pipe 38 through the second one-way valve 37.

[0154] Part of the gas in the air supply pipe 38 enters the two connecting seats 26 and is then output through the second nozzle 27. The airflow output from the second nozzle 27 blows away the soil on the roots of the bok choy, thus achieving the initial cleaning of the bok choy.

[0155] When the bok choy falls above the mesh plate 14 in the water tank 11, the switch of the third motor 31 is turned on. When the third motor 31 is working, it drives the hollow shaft 43 to rotate, which in turn drives the mesh plate 14 to rotate, so that the bok choy moves with the mesh plate 14. At this time, some of the gas in the air supply pipe 38 enters the space below the partition plate 45 in the water tank 11, which causes the air pressure in the space to rise. Then, the water in the space is input into the annular pipe 12 through the connecting pipe 46, and then sprayed out through the first nozzle 13. The sprayed water flow is used to rinse the bok choy again. During the rinsing process, the water passes through the mesh plate 14 and enters the space above the partition plate 45. At this time, the partition plate 45 is sealed, so the water stays above the partition plate 45.

[0156] After the bok choy is rinsed, the switch of the electric push rod 21 is turned on. When the electric push rod 21 is working, it drives the plate 23 to move, which in turn moves the strong magnet 54 on the plate 23 to above the electromagnet 49. Through the repulsive force between the strong magnet 54 and the electromagnet 49, the electromagnet 49 is lowered, which in turn drives the sealing block 51 to lower through the sleeve rod 50, compressing the spring 53. After the sealing block 51 is lowered, the water above the partition 45 enters the area below the partition 45 through the through hole 48.

[0157] After the plate 23 moves to the upper surface of the mesh plate 14, the bok choy follows the rotation of the mesh plate 14, allowing the bok choy to move along the surface of the plate 23 to the guide plate 20, and then enter the box 19 through the guide plate 20.

[0158] In summary, this process enables the harvesting and cleaning of bok choy.

[0159] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
