[0005] To solve the above technical problems, this invention proposes the following technical solutions: A Houttuynia cordata collection device, which includes a vehicle body for driving the whole device to walk automatically. At the front end of the vehicle body, a collection mechanism for collecting Houttuynia cordata is fixedly installed. The collection mechanism is connected to a water tank for supplying water through a water pipe. The water tank is fixedly installed on both sides of the rear end of the vehicle body. A storage frame for collecting the Houttuynia cordata after collection is fixedly installed behind the collection mechanism. The vehicle body moves forward intermittently in the Houttuynia cordata planting area, and the collection mechanism realizes the separation and collection of Houttuynia cordata from the soil by means of high-pressure water flushing.

[0006] The collection mechanism includes a support frame, a spray head, a pipe clamp, a piston rod connecting piece, an oil cylinder fixing seat, a first oil cylinder, a water pipe joint, a connecting seat, a second oil cylinder, a first pin shaft, a third oil cylinder, an L-shaped support arm, a second pin shaft, a U-shaped support arm, a third pin shaft, a pushing bucket and a U-shaped shovel. The oil cylinder fixing seats are symmetrically arranged at the upper end of the support frame. A first oil cylinder is respectively installed on each oil cylinder fixing seat. The piston rod connecting piece is located at the lower end of the first oil cylinder. The piston rod connecting piece is assembled with the piston rod head of the first oil cylinder. The piston rod connecting pieces are symmetrically fixed on the outer side walls of the U-shaped shovel. The spray heads are respectively fixed on the inner side walls of the U-shaped shovel through pipe clamps. The water pipe joint is a flexible hose, and two ends are respectively connected with joints. One joint is connected to the spray head, and the other joint is connected to the water pipe.

[0007] The U-shaped support arm is installed at the rear end of the fixed support frame. On both sides of the top of the U-shaped support arm, L-shaped support arms are respectively hinged through second pin shafts. The other ends of the two L-shaped support arms and the bottom of the connecting seat are hinged through two third pin shafts. One ends of two groups of second oil cylinders are respectively hinged with the corner positions of the two L-shaped support arms through two first pin shafts. The other ends of the two groups of second oil cylinders and the top of the connecting seat are hinged through two third pin shafts. One ends of two groups of third oil cylinders are respectively hinged with the corner positions of the two L-shaped support arms through two first pin shafts. The other ends of the two groups of third oil cylinders and both sides of the U-shaped support arm are hinged through two second pin shafts. The pushing bucket is installed on the front end face of the connecting seat.

[0008] The front end of the pushing bucket is of a toothed structure. A number of protrusions and round holes are evenly distributed in the middle of the pushing bucket. The protrusions are used to fix the houttuynia cordata, and the round holes are used for water filtration.

[0009] The U-shaped shovel is of a U-shaped structure, and the bottom is a blade inclined 15°-20° inward, which is convenient for cutting the houttuynia cordata in the area inside the U-shaped shovel; the water outlet of the nozzle is of a flat structure, and the inclination angle of the nozzle is the same as that of the bottom of the U-shaped shovel, which is convenient for the nozzle to spray water to the bottom and the middle of the U-shaped shovel, realizing the rapid separation of the houttuynia cordata from the soil.

[0010] A high-pressure water pump for providing high-pressure water is arranged inside the water tank, and the water outlet of the high-pressure water pump is connected with a water pipe.

[0011] For the method of collecting houttuynia cordata by using the houttuynia cordata collecting device, the initial state of the collecting mechanism is as follows: the vehicle body is in a stopped forward state, the first oil cylinder retracts to drive the U-shaped shovel to be lifted in place, ensuring that the distance between the U-shaped shovel and the ground is ≥0.1 meter, and the pushing bucket is in a lifted state, ensuring that the bottom of the pushing bucket is higher than the top of the U-shaped shovel. The collecting method includes the following steps:

[0012] Step1, the vehicle body moves forward: operate the vehicle body to move forward in the houttuynia cordata planting area and stop when the driving distance is equal to the length of the U-shaped shovel;

[0013] Step2, shoveling and cutting: the piston rods of the four groups of first oil cylinders in the collecting mechanism extend, and drive the U-shaped shovel and the nozzle to descend in place through the piston rod connecting piece, so that the U-shaped shovel and the nozzle are synchronously inserted into the soil, and the bottom blade of the U-shaped shovel cuts the houttuynia cordata in the soil;

[0014] Step3, flushing and separating: start the high-pressure water pump in the water tank, and the high-pressure water is sprayed out successively through the water pipe, the water pipe joint and the nozzle, realizing the separation of the houttuynia cordata and the soil in the area of the U-shaped shovel, and finally cleaning the soil completely, and then stop the high-pressure water pump in the water tank;

[0015] Step 4, Pushing and Gathering: First, operate the second oil cylinder to retract and the third oil cylinder to extend to make the pushing bucket move, ensuring that the bottom of the pushing bucket is flush with the bottom of the U-shaped shovel when it descends in place; second, retract the first oil cylinder to drive the U-shaped shovel to lift in place; third, operate the vehicle body to move forward for the length of the U-shaped shovel and then stop. While the vehicle body is moving forward, the pushing bucket moves forward synchronously and gathers the heartleaf houttuynia that has been separated in Step 3 into the pushing bucket.

[0016] Step 5, Lifting and Flipping: Operate the second oil cylinder and the third oil cylinder to extend to make the pushing bucket perform upward lifting and flipping actions, and finally the pushing bucket is directly above the storage bin.

[0017] Step 6, Collecting: Operate the second oil cylinder to extend to make the pushing bucket perform a downward flipping action, and the heartleaf houttuynia falls into the storage bin when the pushing bucket flips, completing the collection. The collection mechanism operates to the initial state.

[0018] Step 7, Repeat the operations of Step 2 to Step 6. When the storage bin is full of collected heartleaf houttuynia, empty and transfer it manually. When the collection of the heartleaf houttuynia planting area is completed along the forward direction of the vehicle body, operate the vehicle body to turn around to achieve the collection of another area.

[0019] The present invention has the following beneficial effects:

[0020] 1.

The vehicle body 1 moves forward intermittently in the Houttuynia cordata planting area, and the collection mechanism 2 realizes the separation and collection of Houttuynia cordata from the soil by means of high-pressure water flushing. By adopting the collection device with the above structure, the automatic collection of Houttuynia cordata can be realized, and the damage to Houttuynia cordata can be effectively reduced during the collection process, and the operation efficiency is high. During the specific working process, the vehicle body 1 drives the whole device to move forward intermittently along the Houttuynia cordata planting area. During its forward movement, the Houttuynia cordata inside the soil is cut and shoveled up by the collection mechanism 2, and water is supplied by the water tank 5 to wash it, realizing the separation of Houttuynia cordata and soil.

[0044] Further, the collection mechanism 2 includes a support frame 201, a spray head 202, a pipe clamp 203, a piston rod connecting piece 204, an oil cylinder fixing seat 205, a first oil cylinder 206, a water pipe joint 207, a connecting seat 208, a second oil cylinder 209, a first pin shaft 210, a third oil cylinder 211, an L-shaped support arm 212, a second pin shaft 213, a U-shaped support arm 214, a third pin shaft 215, a pushing bucket 216 and a U-shaped shovel 217. The oil cylinder fixing seats 205 are symmetrically arranged at the upper end of the support frame 201. A first oil cylinder 206 is installed on each oil cylinder fixing seat 205. The piston rod connecting piece 204 is located at the lower end of the first oil cylinder 206. The piston rod connecting piece 204 is assembled with the piston rod head of the first oil cylinder 206. The piston rod connecting pieces 204 are symmetrically fixed on the outer side wall of the U-shaped shovel 217. The spray heads 202 are respectively fixed on the inner side wall of the U-shaped shovel 217 through the pipe clamps 203. The water pipe joint 207 is a flexible hose, and two ends are respectively connected with joints. One joint is connected to the spray head 202, and the other joint is connected to the water pipe 4. By adopting the above collection mechanism 2, the corresponding collection process can be realized. During the specific working process, the first oil cylinder 206 can be used to drive the U-shaped shovel 217 to move downward, so that the U-shaped shovel 217 is inserted into the soil to cut the Houttuynia cordata inside the soil. Water is sprayed through the corresponding spray heads 202 to realize the corresponding cleaning action, and thus the separation between Houttuynia cordata and soil is realized.

[0045] Further, the U-shaped support arm 214 is installed at the rear end of the fixed support frame 201. On both sides of the top of the U-shaped support arm 214, L-shaped support arms 212 are respectively hinged by second pin shafts 213. The other ends of the two L-shaped support arms 212 and the bottom of the connecting seat 208 are hinged by two third pin shafts 215. One ends of the two groups of second oil cylinders 209 are respectively hinged to the corner positions of the two L-shaped support arms 212 by two first pin shafts 210, and the other ends of the two groups of second oil cylinders 209 and the top of the connecting seat 208 are hinged by two third pin shafts 215. One ends of the two groups of third oil cylinders 211 are respectively hinged to the corner positions of the two L-shaped support arms 212 by two first pin shafts 210, and the other ends of the two groups of third oil cylinders 211 and both sides of the U-shaped support arm 214 are hinged by two second pin shafts 213. The pushing bucket 216 is installed on the front end face of the connecting seat 208. Through the cooperation between the U-shaped support arm 214 and the L-shaped support arm 212, the corresponding pushing bucket 216 can be driven to complete the pushing and turning actions of the houttuynia cordata.

[0046] Further, the front end of the pushing bucket 216 is a toothed structure, and a plurality of protrusions and round holes are evenly distributed in the middle of the pushing bucket 216. The protrusions are used to fix the houttuynia cordata, and the round holes are used for water filtration. Through the above-mentioned pushing bucket 216, an effective separation purpose is achieved, and the separation of the houttuynia cordata is realized.

[0047] Further, the U-shaped shovel 217 is of a U-shaped structure, and the bottom is a blade inclined 15°-20° inward, which is convenient for cutting the houttuynia cordata in the area inside the U-shaped shovel 217; the water outlet of the nozzle 202 is of a flat structure, and the inclination angle of the nozzle 202 is the same as that of the bottom of the U-shaped shovel 217, which is convenient for the nozzle 202 to spray water to the bottom and the middle of the U-shaped shovel 217, so as to realize the rapid separation of the houttuynia cordata from the soil. The U-shaped shovel 217 with the above structure mainly realizes the cutting of the houttuynia cordata, and then it is convenient to turn up the houttuynia cordata from the soil body later.

[0048] Further, a high-pressure water pump for providing high-pressure water is arranged inside the water tank 5, and the water outlet of the high-pressure water pump is connected to the water pipe 4. The high-pressure water pump can be used to provide high-pressure cleaning water. During the working process, the high-pressure water pump in the water tank 5 is started, and the high-pressure water is sprayed out successively through the water pipe 4, the water pipe joint 207 and the nozzle 202, so as to realize the separation of the houttuynia cordata and the soil in the area of the U-shaped shovel 217, and finally clean the soil, and then the high-pressure water pump in the water tank 5 stops running.
