[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combine the following Figure 1-Figure 3 The invention discloses a drainage rotary wing and a vegetable and fruit harvester.

[0023] like Figure 1As shown, in the prior art, the harvesting platform 700 cuts the peppers and branches together, and the peppers and branches are separated in the cleaning mechanism 300. The separated peppers enter the collection box 500, and the branches and leaves fall along the partition 600 into the gap between the collection box 500 and the cleaning mechanism 300, covering the body 200. When there are many branches and leaves accumulated in the gap, it not only affects the discharge of the partition 600, but also affects the heat dissipation of the equipment in the cabin of the body 200. Based on this, an embodiment of the present invention provides a drainage rotary wing 100, which is arranged in the gap between the cleaning mechanism 300 and the collection box 500, and the branches and leaves falling on the drainage rotary wing 100 can be transported and shaken off to the outside of the body 200 to avoid the accumulation of branches and leaves on the body 200.

[0024] like Figure 2 As shown, in an embodiment of the present invention, the drainage rotary wing 100 includes: a transmission mechanism, a drainage mechanism, a detection mechanism and a controller. The transmission mechanism and the drainage mechanism are used to be arranged in the gap between the cleaning mechanism 300 and the collecting box 500 of the vegetable and fruit harvester, and the transmission mechanism and the drainage mechanism are arranged adjacent to each other. The detection mechanism is arranged on the transmission mechanism, and the detection mechanism is used to detect whether there are branches and leaves on the transmission mechanism. When there are branches and leaves on the transmission mechanism, the detection mechanism sends a signal to the controller, and the controller controls the transmission mechanism and the drainage mechanism to move. The transmission mechanism transmits the branches and leaves to the drainage mechanism, and the drainage mechanism shakes off the branches and leaves to the outside of the vegetable and fruit harvester by reciprocating up and down swinging.

[0025] Specifically, when in use, the conveying mechanism and the drainage mechanism are arranged between the collecting box 500 and the cleaning mechanism 300 of the vegetable and fruit harvester, and the two are arranged adjacent to each other to ensure that the conveying mechanism can convey the branches and leaves to the drainage mechanism when conveying. When the vegetable and fruit harvester harvests vegetables and fruits, when branches and leaves fall on the conveying mechanism, the conveying mechanism sends a signal to the controller, and the controller controls the actions of the conveying mechanism and the drainage mechanism, and the conveying mechanism conveys the branches and leaves to the drainage mechanism, and the drainage mechanism shakes the branches and leaves off the body 200 by reciprocating up and down.

[0026] The drainage rotary wing provided in the embodiment of the present invention, by setting a detection mechanism, a transmission mechanism and a drainage mechanism, can transmit the branches and leaves to the drainage mechanism when there are branches and leaves on the transmission mechanism, and shake the branches and leaves off the body through the up and down reciprocating swing of the drainage mechanism, thereby avoiding the accumulation of branches and leaves on the body, ensuring the heat dissipation effect of the cabin equipment in the body, reducing the mechanical failure rate, and eliminating the safety hazard of fire caused by heat dissipation failure.

[0027] like Figure 2As shown, in an embodiment of the present invention, the transmission mechanism includes: a second driver 10, a driving shaft 11, a driven shaft 12 and a conveyor belt 13. The driving shaft 11 and the driven shaft 12 are connected by the conveyor belt 13, and the second driver 10 is connected to the driving shaft 11. When the controller receives a signal sent by the detection mechanism, the controller controls the second driver 10 to rotate to drive the driving shaft 11 and the driven shaft 12 to rotate, so as to transport the branches and leaves to the drainage mechanism through the conveyor belt 13. In this embodiment, the second driver 10 can be a rotary motor.

[0028] In an embodiment of the present invention, the detection mechanism includes a photoelectric sensor. The photoelectric sensor is arranged on the conveying mechanism and is electrically connected to the controller.

[0029] Specifically, the photoelectric sensor includes a transmitter 21 and a receiver 22. The transmitter 21 is arranged on the driving shaft 11 through a connecting kit. The driving shaft 11 can rotate relative to the connecting kit. When the driving shaft 11 rotates, the connecting kit does not move, so the transmitter 21 does not move. Correspondingly, the receiver 22 is also arranged on the driven shaft 12 through a connecting kit. The driven shaft 12 can rotate relative to the connecting kit. When the driven shaft 12 rotates, the receiver 22 does not move. When there are branches and leaves on the conveyor belt 13, the light beam emitted by the transmitter 21 is blocked by the branches and leaves, and the receiver 22 cannot receive the light beam. The transmitter 21 sends a signal to the controller, and the controller controls the second driver 10 to operate, driving the conveyor belt 13 to transfer the branches and leaves to the drainage mechanism.

[0030] like Figure 2 As shown, in an embodiment of the present invention, the detection mechanism also includes a visual acquisition element 23, which is arranged on the driven shaft 12, and its arrangement can refer to the arrangement of the receiving end 22. The visual acquisition element 23 is used to acquire image information on the conveyor belt 13, and the image information acquired by the visual acquisition element 23 can be displayed in real time on the vegetable and fruit harvester, and the operator can know the accumulation of branches and leaves on the conveyor belt 13 in real time. When the branches and leaves on the conveyor belt 13 are blocked, the operator can manually clean the branches and leaves on the conveyor belt 13 according to the displayed image information to ensure the normal operation of the conveyor belt 13. Optionally, the visual acquisition element 23 can be a camera or an industrial camera.

[0031] like Figure 2As shown, in an embodiment of the present invention, the drainage mechanism includes: a first driver 31 and a drainage plate 32, the first driver 31 is connected to the drainage plate 32, and the first driver 31 is used to drive the drainage plate 32 to swing back and forth up and down. When the detection mechanism detects that there are branches and leaves on the conveyor belt 13, the detection mechanism sends a signal to the controller, and the controller controls the second driver 10 to rotate, driving the conveyor belt 13 to transmit, and the conveyor belt 13 conveys the branches and leaves to the drainage plate 32. Under the action of the first driver 31, the drainage plate 32 swings back and forth up and down to shake off the branches and leaves on the drainage plate 32. In this embodiment, the drainage plate 32 extends to the outside of the body 200 of the vegetable and fruit harvester to shake off the branches and leaves outside the body 200.

[0032] Optionally, the first driver 31 may be a reciprocating motor. Based on the principle that the reciprocating motor regularly swings up and down within a certain angle range, the branches and leaves on the guide plate 32 are accelerated to slide, so as to quickly transport the branches and leaves to the outside of the body 200.

[0033] like Figure 2 As shown, in an embodiment of the present invention, the drainage rotary wing 100 further includes a pair of brackets 40, which are arranged in parallel and are used to be connected to a vegetable and fruit harvester. The first end of each bracket 40 is connected to the driving shaft 11 and the driven shaft 12, and the second end of each bracket 40 is connected to the first driver 31. In this embodiment, the transmission mechanism and the drainage mechanism are connected as a whole by a pair of brackets 40. When the drainage rotary wing 100 is set on the vegetable and fruit harvester, the bracket 40 can be connected to the crossbeam 400 of the vegetable and fruit harvester and the frame of the collection box 500, thereby fixing the drainage rotary wing 100 on the vegetable and fruit harvester.

[0034] Furthermore, each bracket 40 includes: a first support rod 41 and a second support rod 42, the first support rod 41 and the second support rod 42 are arranged at an angle and connected, the first support rod 41 is rotationally connected to the driving shaft 11 and the driven shaft 12, and the second support rod 42 is connected to the first driver 31.

[0035] Specifically, the first support rod 41 and the second support rod 42 are arranged at an angle so that after the drainage rotary wing 100 is installed on the frame of the crossbeam 400 and the collection box 500, the conveyor belt 13 is in a horizontal state, and the drainage plate 32 is inclined relative to the conveyor belt 13 to facilitate shaking off branches and leaves. The core of the driving shaft 11 and the driven shaft 12 can be provided with a connecting shaft, and the driving shaft 11 and the driven shaft 12 are both sleeved on the outside of the connecting shaft and can rotate relative to the connecting shaft. Each first support rod 41 is respectively connected to one end of a pair of connecting shafts. The second support rod 42 can be connected to the housing of the first driver 31 so that the second support rod 42 remains stationary when the first driver 31 swings back and forth.

[0036] like Figure 2 As shown, in an embodiment of the present invention, the drainage rotor 100 also includes a temperature sensor 50, which is arranged on the conveyor belt 13. The temperature sensor 50 is used to detect the temperature of the conveyor belt 13 and send a warning signal to the controller when the temperature of the conveyor belt 13 reaches a preset value. The controller controls the second driver 10 to stop rotating to avoid the conveyor belt 13 from being too hot and causing a fire.

[0037] like Figure 3 As shown, an embodiment of the present invention further provides a vegetable and fruit harvester, comprising: a machine body 200, a cleaning mechanism 300, a crossbeam 400, a material collection box 500 and a drainage rotary wing 100. The cleaning mechanism 300 and the material collection box 500 are both arranged on the machine body 200, and a frame is also arranged on the machine body 200, and the crossbeam 400 is connected to the frame, and the crossbeam 400 is located between the cleaning mechanism 300 and the material collection box 500. The drainage rotary wing 100 is arranged on the crossbeam 400 and the frame of the material collection box 500.

[0038] The drainage rotary wing 100 includes: a transmission mechanism, a drainage mechanism, a detection mechanism and a controller. When the vegetable and fruit harvester harvests vegetables and fruits, the cleaning mechanism 300 separates the vegetables and fruits from the branches and leaves, and the separated branches and leaves are discharged by the cleaning mechanism. When branches and leaves fall on the transmission mechanism, the transmission mechanism sends a signal to the controller, and the controller controls the transmission mechanism and the drainage mechanism to move. The transmission mechanism transmits the branches and leaves to the drainage mechanism, and the drainage mechanism shakes the branches and leaves off the body 200 by reciprocating up and down.

[0039] The vegetable and fruit harvester provided by the embodiment of the present invention is provided with a drainage rotary wing. When the cleaning mechanism transports branches and leaves outward, when branches and leaves fall on the conveying mechanism, the branches and leaves are conveyed to the drainage mechanism. The drainage mechanism swings back and forth to shake the branches and leaves off the body, thereby avoiding the accumulation of branches and leaves on the body and ensuring the heat dissipation effect of the body.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
