Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machinery, in particular to the technical field of safflower harvesting, and more particularly to a brush roller type safflower harvester. BACKGROUND

[0002] As a kind of precious Chinese herbal medicine, safflower is widely planted at home and abroad, and is still in short supply at present. The harvesting process of safflower production still needs a large amount of manual work to harvest single flowers, and the flower filaments need to be pulled out one by one, which increases the production cost and the labor intensity. Therefore, in the process of safflower harvesting, it is urgent to design an agricultural intelligent equipment which is easy to use and can significantly improve the harvesting efficiency of safflower.

[0003] The utility model with the application number 202220356015.1 discloses a backpack type crocus sativus L. harvester. The harvester rolls the crocus sativus L. and leaves to be harvested into the harvesting box with negative pressure through the rotation of the harvesting roller shaft, thereby completing the harvesting of crocus sativus L. However, the harvester needs to be carried by hand, which is easy to cause fatigue and affect the harvesting efficiency of crocus sativus L.

[0004] The invention patent with the application number 202111147750.8 discloses a low type safflower profiling harvester and a harvesting method. The multi-flower picking end effector of the harvester is arranged according to the fruit ball distribution law, and different heights of fruit balls are picked at the same time. However, the mechanical structure of the harvester is complex, and the manufacturing cost is high.

[0005] In summary, there is an urgent need for a safflower harvester which is easy to operate and has high harvesting rate to solve the problems of low harvesting efficiency and high cost in the prior art. SUMMARY

[0006] The present application provides a brush roller type safflower harvester and its use method to solve the problems of low harvesting efficiency and high cost in the prior art. The present application adopts a multi-roller harvesting device. The brush can roll the single cluster of safflower multiple times during the harvesting process to ensure high net harvesting rate and harvesting rate. The operation is simple, and the cost is low.

[0007] The present application is realized by the following technical scheme. A brush roller type safflower harvester includes a horizontally moving main body, a multi-roller harvesting device and a pushing device arranged longitudinally on the main body. The multi-roller harvesting device includes a plurality of brush rollers arranged in sequence along the moving direction of the main body and extending vertically, and a first driving device driving the plurality of brush rollers to rotate. The circumferential surface of the brush roller is provided with a plurality of brush filaments in contact with safflower. The pushing device includes a profiling concave plate sliding on the main body in the longitudinal direction, and a second driving device driving the profiling concave plate to slide. The safflower is located between the brush roller and the profiling concave plate.

[0008] This invention utilizes the combination of brush rollers and contoured concave plates to perform multiple brushing operations on a single cluster of safflower while simultaneously using the contoured concave plates to push the safflower towards the brush rollers, thereby ensuring a high harvesting rate and a high cleanliness rate. Furthermore, the arrangement of multiple brush rollers allows for multiple harvests during a single safflower harvesting process, effectively preventing missed harvesting. Simultaneously, the movement of the main body facilitates safflower harvesting, making operation convenient. Compared to existing harvesting machines, this solution has a lower manufacturing cost.

[0009] Preferably, the main body also includes a blower pipe and a collection box arranged longitudinally. The blower pipe and the contoured concave plate are located on one side of the safflower, and the brush roller and the collection box are located on the other side of the safflower. The contoured concave plate and the brush roller are located between the blower pipe and the collection box. The blower pipe has holes for blowing air into the collection box, and the contoured concave plate has several elongated holes for the safflower filaments to pass through.

[0010] This preferred solution uses a blower pipe to blow the safflower filaments brushed off by the brush roller, which then pass through the contoured concave plate and into the collection box, thus collecting the safflower filaments.

[0011] Preferably, the brush roller is connected to the main body via a rotating shaft. The first driving device includes a rotating wheel fixed to the rotating shaft, a tensioning wheel located between two adjacent rotating wheels and connected to the main body, and a multi-wedge belt II that passes around the rotating wheel and the tensioning wheel in a transverse direction. The main body is also provided with a speed-regulating motor II that drives the multi-wedge belt II.

[0012] This preferred solution, through the setting of speed-regulating motor II and multi-wedge belt II, enables several brush rollers to share a single power source while simultaneously rotating the brush rollers. At the same time, the setting of tensioning wheel enables the multi-wedge belt II to be tensioned.

[0013] Preferably, the main body is also connected to a number of anti-tangle ropes that extend laterally and are arranged vertically. The anti-tangle ropes pass around the brush roller in sequence, and both ends of the anti-tangle ropes are fixed to the main body.

[0014] This preferred solution effectively prevents the roller brush from becoming tightly entangled with the safflower plant by setting an anti-tangling rope.

[0015] Preferably, the main body is fixedly connected to a plurality of telescopic sleeves extending longitudinally, and the contoured concave plate is fixedly connected to a telescopic shaft inserted into and sliding within the telescopic sleeves. A return spring is sleeved on the telescopic shaft, and the two ends of the return spring are fixedly connected to the telescopic shaft and the telescopic sleeves respectively. The second driving device includes a speed-regulating motor I mounted on the main body, and a cam keyed to the motor shaft of the speed-regulating motor I and abutting the side of the contoured concave plate away from the red flower.

[0016] In use, the speed-regulating motor I drives the cam to rotate, and the cam tops onto the contouring concave plate. Through the telescopic shaft sliding within the telescopic sleeve, the contouring concave plate moves longitudinally under the drive of the cam. Due to the setting of the return spring, the return spring drives the telescopic shaft to reset the contouring concave plate, thereby realizing the longitudinal sliding of the contouring concave plate.

[0017] Preferably, the main body is also axially connected to a feeding roller brush I on the same side as the contoured concave plate. The speed-regulating motor I drives the feeding roller brush I to rotate through a multi-wedge belt I. The main body is also axially connected to a feeding roller brush II that cooperates with the feeding roller brush I and is on the same side as the brush roller. The speed-regulating motor II drives the feeding roller brush II to rotate through a multi-wedge belt II.

[0018] This preferred solution provides a guiding effect for safflower by setting up feeding roller brush II and feeding roller brush I.

[0019] Preferably, the contoured concave plate includes an arc segment adapted to the brush roller, and a straight segment connecting two adjacent arc segments and adapted to the gap between two adjacent brush rollers, with a plurality of elongated holes arranged vertically and all inclined upward, the elongated holes spanning the arc segment and the straight segment.

[0020] This preferred design, through the setting of elongated holes, works in conjunction with the bristles on the brush roller to facilitate the collection of safflowers, while also allowing air from the blower to pass through the elongated holes, ensuring the collection of safflowers.

[0021] Preferably, the blower includes a plurality of horizontally extending and vertically arranged air outlet pipes, and a main air pipe connected to the air outlet pipes. A plurality of holes are formed on the air outlet pipes and the plurality of holes are arranged horizontally. The main air pipe is also provided with two air inlets.

[0022] This preferred design ensures sufficient air is delivered to the outlet duct and ejected from the holes by setting up the main air duct and two air inlets.

[0023] Preferably, the main body includes a frame, four omnidirectional casters mounted on the frame and arranged in a rectangular pattern, and a stalk support plate I and a stalk support plate II mounted on the frame and arranged longitudinally. A push handle is also provided at the rear of the frame.

[0024] This preferred solution facilitates the movement of the main body by incorporating a frame and swivel casters, thus making operation easier.

[0025] A method for using a brush roller type safflower harvester includes the following steps:

[0026] During the harvesting of safflower filaments, a speed-regulating motor II drives several brush rollers and a feeding roller II to rotate. Then, a speed-regulating motor I drives a cam and a feeding roller I to rotate. As the cam rotates, it pushes a contouring concave plate towards the brush rollers. Then, it pushes a push handle to move the frame towards the safflower, causing the safflower to enter between the contouring concave plate and several brush rollers from between the feeding rollers II and I. At this time, air is delivered to the air pipe, and the air flows towards the contouring concave plate through the holes. The brush rollers and the contouring concave plate collect the safflower filaments, and the safflower filaments are blown into the collection box by air sprayed out from the holes, thus completing the harvesting of safflower filaments.

[0027] The beneficial effects of this invention are as follows: by combining the brush roller and the contouring concave plate, the safflower is brushed multiple times on a single cluster while the contouring concave plate pushes the safflower onto the brush roller, thereby ensuring the cleanliness and harvest rate. At the same time, the arrangement of multiple brush rollers allows for multiple harvests during a single safflower harvesting process, effectively preventing missed harvesting of safflower. Simultaneously, the movement of the main body enables the harvesting of safflower, making operation convenient. Compared with existing harvesting machines, this solution has a lower manufacturing cost.

[0028] In this invention, the brush roller extends vertically, that is, it extends along the height direction, thereby achieving efficient and rapid harvesting of safflower filaments at different heights; by setting up the anti-tangling rope, the problem of tight entanglement between safflower plants and harvesting roller brush is effectively reduced, the filament harvesting rate is improved, and the harvesting cost is reduced.

[0029] This invention, through the setting of a contoured concave plate, uses the rotation of a cam to drive the movement of the contoured concave plate and interact with the harvesting device, effectively improving the harvesting efficiency of the harvester.

[0030] This invention, through the design of the frame and swivel casters, can effectively avoid the high-intensity labor caused by frequent bending over, thus ensuring efficient safflower harvesting operations. Attached Figure Description

5. The brush roller type safflower harvester according to claim 4, characterized in that: The main body (1) is also shaft-connected with a feeding roller brush I (2007) on the same side as the contoured concave plate (4002). The speed-regulating motor I drives the feeding roller brush I to rotate through the multi-wedge belt I (3024). The main body (1) is also shaft-connected with a feeding roller brush II (2006) that cooperates with the feeding roller brush I and is on the same side as the brush roller. The speed-regulating motor II drives the feeding roller brush II to rotate through the multi-wedge belt II (3002).

6. The brush roller type safflower harvester according to claim 1, characterized in that: The blower pipe (5004) includes a plurality of horizontally extending and vertically arranged air outlet pipes (5003), and a main air pipe connected to the air outlet pipes (5003). A plurality of holes are formed on the air outlet pipes (5003), and the plurality of holes are arranged horizontally. Two air inlets are also formed on the main air pipe.

7. The brush roller type safflower harvester according to claim 5, characterized in that: The main body (1) includes a frame (1005), four omnidirectional casters (1003) mounted on the frame (1005) and arranged in a rectangular shape, and a shovel I (1001) and a shovel II (1002) mounted on the frame (1005) and arranged longitudinally. A push handle (1004) is also provided at the rear of the frame (1005).

8. The method of using the brush roller type safflower harvester according to claim 7, characterized in that, Includes the following steps: During the safflower filament harvesting process, the speed-regulating motor II drives several brush rollers and the feeding roller brush II to rotate. Then, the speed-regulating motor I drives the cam (4001) and the feeding roller brush I to rotate. When the cam (4001) rotates, it pushes the contour plate (4002) to move towards the brush rollers. Then, it pushes the push handle (1004) to move the frame (1005) towards the safflower, so that the safflower enters between the contour plate (4002) and several brush rollers from between the feeding roller brush II and the feeding roller brush I. At this time, air is delivered to the air pipe (5004). The air flows along the holes towards the contour plate (4002). At this time, the brush rollers and the contour plate (4002) collect the safflower filaments and blow the safflower filaments into the collection box (5005) by spraying air from the holes, thus completing the safflower filament harvesting.
