[0008] Preferably, the collection box is detachably connected with a cleaning cover.

[0009] Preferably, the inner bottom wall of the collection box is inclinedly arranged.

[0010] Preferably, the collection frame is connected with a handle.

[0011] Preferably, the cutting platform is rotationally connected with a belt conveyor, the belt conveyor is rotationally connected with a hydraulic rod, and the extension end of the hydraulic rod is rotationally connected with the cutting platform.

[0012] Compared with the prior art, the technical scheme has the beneficial effects that:

[0013] (1) The belt conveyor, the cutting platform and the cutting mechanism are cooperated to realize integrated and coherent operation from cutting to conveying. After the low crops are cut by the cutting mechanism, the belt conveyor can timely convey the crops to the collecting box, reducing manual intervention, improving harvesting efficiency, reducing labor intensity, and avoiding accumulation of crops in the field. The screen, the rotating shaft and the eccentric wheel are arranged to drive the collecting frame to vibrate, so that the screen vibrates, effectively screening the crops in the collecting frame, and the particles such as soil and small stones mixed in the crops are screened out through the screen, improving the purity of the crops and reducing the impurity processing link in the subsequent processing process. The air suction port and the air suction fan assembly are arranged to form a negative pressure below the collecting frame, and the light impurities such as weeds and broken leaves mixed in the harvesting process are sucked out of the collecting frame, further improving the cleanliness of the crops.

[0014] (2) The filter screen is arranged to prevent impurities such as weeds and broken leaves from entering the air suction fan assembly, thereby protecting the blades and motor of the air suction fan and reducing the wear and blockage caused by impurities, prolonging the service life of the air suction fan assembly.

[0015] (3) The cleaning cover is arranged to directly clean the bottom of the collecting box without the need to disassemble or dump the crops in the collecting box, so that the impurities can be quickly and effectively removed, saving cleaning time and labor cost.

[0016] (4) The inner bottom wall of the collecting box is inclined, so that the impurities in the collecting box can automatically gather at the lower end under the action of gravity, facilitating the impurities to be concentrated and discharged through the cleaning cover, avoiding the impurities to be dispersed and accumulated at various positions of the bottom of the box, and improving the efficiency of cleaning the impurities. The inclined bottom wall can make the impurities naturally slide and accumulate in the box, avoiding excessive accumulation of the impurities in a certain area of the box, so that the space of the collecting box can be more fully utilized, and the collecting efficiency is improved.

[0017] (5) The handle is arranged to provide an operating point for the operator, so that the operator can easily grasp the handle to push, pull or lift the collecting frame. When the collecting frame is loaded into or unloaded from the collecting box, the handle can be used to more easily and accurately control the movement of the collecting frame, reducing the operation difficulty and improving the work efficiency.

[0018] (6) By setting up hydraulic rods, the angle between the header and the belt conveyor can be changed, thereby flexibly adjusting the tilt angle of the header. When harvesting low-growing crops of different heights and growth stages, the header can be adjusted to the optimal harvesting angle to ensure that the cutting mechanism can get closer to the ground and efficiently cut the crops, while avoiding missed cuts or uneven cuts, thus improving harvesting quality and efficiency.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figs. 1-3 The illustrated harvesting device for low-growing crops includes a main body 1. A walking mechanism 2 is connected to the bottom of the main body 1, allowing the harvesting device to move flexibly in the field. A support frame 5 is connected to the top of the main body 1, and a belt conveyor 6 is connected to the top of the support frame 5. The belt conveyor 6 is inclined. A cutting platform 3 is rotatably connected to the left end of the belt conveyor 6, and a hydraulic rod 4 is rotatably connected to the belt conveyor 6. The telescopic end of the hydraulic rod 4 is rotatably connected to the cutting platform 3. A cutting mechanism 9 is connected to the bottom of the cutting platform 3. A collection box 8 is connected to the upper right side of the main body 1, and the right end of the belt conveyor 6 is located above the collection box 8.

[0025] like Fig. 3As shown, the inner side wall of the collecting box 8 is connected with a support ring block 19, the inner side wall of the collecting box 8 is slidingly connected with a collecting frame 12, the upper end surface of the collecting frame 12 is connected with a handle 11 on both sides. The bottom wall of the collecting frame 12 is in contact with the support ring block 19, and the bottom wall of the collecting frame 12 is connected with a screen 13. The left and right side walls of the collecting box 8 are rotatably connected with a rotating shaft 18, the right side wall of the collecting box 8 is connected with a motor 10, the output end of the motor 10 is connected with the rotating shaft 18, the rotating shaft 18 is connected with an eccentric wheel 16, and the eccentric wheel 16 is matched with the screen 13. The motor 10 is started to drive the rotating shaft 18 to rotate, and the rotating shaft 18 drives the eccentric wheel 16 to rotate. Because the center of the eccentric wheel 16 deviates from the shaft center, the screen 13 is constantly lifted upward during rotation, so that the collecting frame 12 is lifted, and then moves away from the screen 13, so that the collecting frame 12 falls, and the periodic motion is repeated, so that the collecting frame 12 vibrates. This vibration can break the static state of crops and impurities on the screen 13, and more impurities can fall through the screen 13.

[0026] As shown in the figure, Fig. 3 The left side wall of the collecting box 8 is provided with an air outlet 14, and the air outlet 14 is located below the support ring block 19. The inner wall of the air outlet 14 is connected with a filter screen 15. The left side wall of the collecting box 8 is connected with an air suction fan assembly 7, and the air suction fan is aligned with the air outlet 14. The air suction fan assembly 7 sucks away the air at the bottom of the collecting box 8, so that the negative pressure is generated below the collecting frame 12. Under the action of negative pressure, the crops and impurities in the collecting frame 12 are subjected to downward suction force. The crops are intercepted by the screen 13 and stay in the collecting frame 12. Some light impurities are relatively light in weight and small in size, and are easily sucked away by the suction force generated by the negative pressure, and fall into the bottom of the collecting box 8 through the screen 13. The inner bottom wall of the collecting box 8 is inclined, and the right side wall of the collecting box 8 is detachably connected with a cleaning cover 17, and the cleaning cover 17 is located at the lowest part of the inner bottom wall of the collecting box 8. The impurities falling on the inner bottom wall of the collecting box 8 slide along the inclined inner bottom wall under the action of gravity and gather near the cleaning cover 17.

[0027] The specific implementation process is as follows:

[0028] In use, the walking mechanism 2 is started to move the harvesting device to the area to be harvested in the field, the position and direction are adjusted, the hydraulic rod 4 is started to make the header 3 at a suitable angle to ensure that the cutting mechanism 9 can smoothly contact the crops. The cutting mechanism 9, the walking mechanism 2, the belt conveyor 6, the motor 10 and the air suction fan assembly 7 are started in turn. The cutting mechanism 9 starts to cut crops, the crops are conveyed into the collecting box 8 by the belt conveyor 6, the screen 13 and the eccentric wheel 16 cooperate to screen, and the air suction fan assembly 7 performs air suction and impurity removal. When the collecting frame 12 is full of crops, the operator holds the handle 11 on the collecting frame 12 to take out the collecting frame 12 from the collecting box 8, and replaces the new collecting frame 12 to continue collecting. The accumulation of impurities on the inner bottom wall of the collecting box 8 is checked regularly, and when there are many impurities, the cleaning cover 17 is detached to clean the impurities.

[0029] The above is only the embodiment of the present application, and the known specific technical solutions and / or common knowledge of characteristics in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
