[0002] Low-stubble harvesters are mainly used to reduce the height of the wheat stubble left in the field after harvesting. In central China, corn will be sown in the next round after wheat harvesting. When the height of the wheat stubble is high, it is easy for the corn grains to be unable to effectively enter the specified soil depth when sown using a seeder, which can easily lead to missing corn seedlings and broken ridges.

This can easily increase the average residual height of the barley stubble when passing through soil with potholes. Therefore, a new type of low-stubble harvester is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] See also Figures 1 to 4 A new type of low-stubble harvester includes a harvesting platform 1, a support frame 2 is fixedly connected to the inner side of the harvesting platform 1, an independent harvesting mechanism 3 is arranged below the harvesting platform 1, a guide angle 4 is fixedly connected to the outer surface of the support frame 2, a guide wheel 5 is rotatably connected to the inner side of the support frame 2, and an induction mechanism 6 is arranged on the outer surface of the guide wheel 5.

[0021] In this embodiment: when the equipment as a whole moves forward, the sensing mechanism 6 can push the guide wheel 5 so that the guide wheel 5 can always stick to the ground to be harvested in front, and the sensing mechanism 6 can collect the moving distance generated when the guide wheel 5 encounters depressions or protrusions from the soil below, and control the real-time up and down movement adjustment of the independent harvesting mechanism 3 at the rear according to the moving distance of the guide wheel 5, so that the harvesting distance can be adjusted in real time when encountering bumpy ground, thereby minimizing the error in the height of the whole acre of wheat stubble, thereby solving the problem of easily increasing the average residual height of the wheat stubble due to passing through soil with potholes.

[0022] As a technical optimization scheme of the utility model, the sensing mechanism 6 includes a fixed seat 601, the bottom surface of the fixed seat 601 is fixedly connected to the outer surface of the guide wheel 5, the inner surface of the fixed seat 601 is rotatably connected to the support rod 602, the outer surface of the support rod 602 is slidably connected to the sliding sleeve 603, the outer surface of the sliding sleeve 603 is rotatably connected to the rotating seat 604, and the outer surface of the rotating seat 604 is fixedly connected to the outer surface of the support frame 2.

[0023] In this embodiment: when the guide wheel 5 rotates up and down, it can push the support rod 602, so that the support rod 602 slides on the inner wall of the sliding sleeve 603. At the same time, the cooperation between the rotating seat 604 and the fixed seat 601 ensures that no matter how much the guide wheel 5 rotates, the support rod 602 and the sliding sleeve 603 remain parallel to each other.

[0024] As a technical optimization scheme of the utility model, the inner wall of the sliding sleeve 603 is provided with a limit cavity 605 and a sensing cavity 606, the outer surface of the support rod 602 is provided with a flange 1 607 and a flange 2 608, the outer surface of the flange is slidably connected to the inner wall of the limit cavity 605, the inner wall of the sensing cavity 606 is installed with an induction ring 609, the outer surface of the flange 2 608 is installed with an electric plate 610, and the inner wall of the flange 2 608 is slidably connected to the inner wall of the induction ring 609.

[0025] In this embodiment: when the support rod 602 moves, it can push the electric plate 610 to move inside the induction ring 609. When the pad moves inside the induction ring 609, it can generate current. The current is transmitted to the analyzer, so that the analyzer outside the device can determine the rotation amplitude of the guide wheel according to the magnitude of the current, and send the result to the main console in real time. At the same time, a spring is sleeved on the outside of the support rod 602, and the spring is installed inside the limit cavity 605, so that the spring can always push the flange 1 607, so that the support rod 602 can always maintain the lowest position when there is no other external force.

[0026] As a technical optimization solution of the utility model, the independent harvesting mechanism 3 includes a sliding rod 301, the top of the sliding rod 301 is fixedly connected to the bottom wall of the harvesting platform 1, the outer surface of the sliding rod 301 is slidably connected to the harvesting seat 302, and the interior of the harvesting seat 302 is installed with a conveyor belt 303 and a cutting disc 304.

[0027] In this embodiment: the conveyor belt 303 can gather the straw in a line, and the cutting disk 304 cuts the straw to form a separate harvesting device. Each conveyor belt 303 and cutting disk 304 are driven by a separate driving device and installed in the harvesting platform 1. The sliding rod 301 can provide a fixed moving direction for the harvesting platform 1.

[0028] As a technical optimization solution of the utility model, the inner wall of the harvesting platform 1 is threadedly connected with a threaded rod 305, the inner wall of the threaded rod 305 is rotatably connected to the inner wall of the harvesting platform 1, and the top of the threaded rod 305 is fixedly connected with a driven gear 306.

[0029] In this embodiment: a bearing is installed inside the threaded rod 305 of the harvesting platform 1, and the bearing is sleeved on the outer surface of the threaded rod 305, so that the threaded rod 305 will be more stable when rotating. When rotating, the driven gear 306 can drive the harvesting platform 1 to move up and down on the outer surface of the sliding rod 301 through the threaded rod 305.

[0030] As a technical optimization solution of the utility model, the outer surface of the driven gear 306 is meshed with a transmission chain 307, the inner surface of the transmission chain 307 is meshed with a driving gear 308, and the bottom surface of the driving gear 308 is rotatably connected to the outer surface of the harvesting platform 1.

[0031] In this embodiment: an independent motor is installed outside the harvesting platform 1 and above each driving gear 308, and the output end of the motor is connected to the driving gear 308. When the motor drives the driving gear 308, the driving gear 308 can drive the driven gear 306 to rotate through the transmission chain 307, and the rotation speeds of the two driven gears 306 are the same.

[0032] As a technical optimization solution of the utility model, the bottom surface of the harvesting platform 1 is fixedly connected to a load-bearing seat 7, and the outer surface of the load-bearing seat 7 is rotatably connected to a load-bearing wheel 8, and the horizontal position of the load-bearing wheel 8 is higher than the guide wheel 5.

[0033] In this embodiment: the load-bearing seat 7 and the load-bearing wheel 8 can bear the weight of the entire equipment. At the same time, because the horizontal position of the load-bearing wheel 8 is slightly higher than the guide wheel 5, the guide wheel 5 can move more sensitively when encountering a downwardly concave ground.

[0034] Working principle: When the equipment is running, the guide wheel 5 can first contact the bottom surface in front. When there are potholes or protrusions on the bottom surface in front, it can drive the support rod 602 to move. The support rod 602 can drive the electric sheet to move. When the electric sheet moves in the induction ring 609, it can generate current. The farther the electric sheet moves upward, the higher the current. At this time, the analyzer can determine the rotation amplitude of the guide wheel 5 according to the magnitude of the current, and inform the main console of the result. The main console will control the motor at the corresponding position, so that the motor can drive the threaded rod 305 to rotate through the driving gear 308 and the driven gear 306. The rotation of the threaded rod 305 can control the harvesting table 1 to move up and down, so that the harvesting disc can always maintain the same distance from the ground.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
