Description

TECHNICAL FIELD

[0001] The utility model relates to an agricultural machinery field especially a harvester. BACKGROUND

[0002] In the harvesting time of rice and wheat, the temperature is hot or cold, and the user uses the air conditioner of the cab to cool or heat. Due to the maturity of crops, the harvester generates a lot of dust and dirt, and there are particles such as willow catkins and poplar catkins in the air. The working environment of the harvester is very bad. After the user uses the air conditioner, the impurities in the air will be sucked into the condenser due to the operation of the condenser fan. These impurities will continuously accumulate on the condenser fins, affecting the use effect of the air conditioner.

[0003] Once the use effect of the air conditioner decreases, the user needs to clean the condenser. Due to the filter screen outside the condenser that blocks large particles, the traditional way is to fix it outside the condenser on the roof of the cab by screws and other fasteners. A special tool is needed to remove a large number of screws and other fasteners, and a large number of disassembly will increase the disassembly time of the filter screen. The user spends a lot of time cleaning the condenser filter screen and the condenser, which reduces the work efficiency. Or the user roughly cleans the condenser filter screen, only cleaning the dust on the outside of the filter screen, and the condenser cannot be deeply cleaned. The cooling effect of the air conditioner will not improve, and the air conditioner system will be damaged due to the large load and the slow heat dissipation.

[0004] Therefore, it is necessary to provide a harvester to overcome the defects in the above. INVENTION CONTENTS

[0005] The utility model aims at providing a harvester, which realizes the blocking of impurities and efficient disassembly and cleaning through the reasonable design of the cab filter screen device, ensures the deep cleaning to reduce the damage probability of the air conditioner system, and saves the disassembly and assembly time of the user.

[0006] According to one aspect of the present invention, a harvester is provided, comprising a cab, a header, a chassis, and a threshing and cleaning system, with the forward direction of the harvester as the front. The header is located in front of the cab for cutting crops and conveying them to the rear. The chassis is located below the cab for driving the harvester. The threshing and cleaning system is used to thresh and clean the crops conveyed by the header. The cab includes a roof, a rear wall, a lower cover, a condenser, and a filter device. The roof is fixed above the cab. The rear wall divides the roof into a main body and an extension extending from the main body to the rear of the cab. The lower cover is located on the lower surface of the extension and has a through-hole for air circulation. The condenser is located between the extension and the lower cover for heat dissipation. The filter device is rotatably or slidably connected to the lower cover via a connecting part to open or close the through-hole. The above solution can save time in disassembling and assembling the filter, reduce the difficulty of disassembly and assembly, thereby improving the efficiency and frequency of filter cleaning, further enabling the air conditioning system to receive more maintenance, improving the efficiency and performance of the air conditioner, and extending the life of the air conditioner.

[0007] Preferably, the connecting part includes a sliding plate that is at least partially disposed around the through-hole and fixed below the lower cover. The edge of the filter device is at least partially positioned between the sliding plate and the lower cover. The filter device can slide along the sliding plate to open or close the through-hole. With the above solution, when cleaning the condenser and filter device, no tools are needed; simply pull out the filter for separate cleaning. Exposed condensers can also be cleaned directly, shortening cleaning time and promoting a deeper and broader cleaning of the condenser.

[0008] Preferably, the chute includes a fixing part fixed to the lower cover and a bending part forming a certain bending space with the lower end of the lower cover. The filter device is at least partially placed in the bending space and can slide along the front-back or left-right direction of the harvester to open or close the through port.

[0009] Preferably, the filter device includes at least one first connecting hole, and the lower cover is provided with at least one threaded hole corresponding to the first connecting hole. The threaded hole and the first connecting hole are connected by a hand-tightening screw to fix the filter device to the lower cover. This solution helps to further secure the filter device, preventing the filter from shifting, while avoiding the problems of difficulty in disassembly or the need for tools.

[0010] Preferably, the connecting part includes a hinge engagement part connecting the cover and the filter device, and the filter device is rotatably connected to the lower cover through the hinge engagement part to open or close the through port.

[0011] Preferably, the hinge matching part comprises a first hinge part fixed to the lower shroud and a second hinge part fixed to the filter screen device, and the first hinge part and the second hinge part are rotationally connected; or the hinge matching part comprises a first hinge part detachably connected to the lower shroud and a second hinge part detachably connected to the filter screen device, and the first hinge part and the second hinge part are rotationally connected. Through the above scheme, the filter screen can be cleaned alone by only turning the filter screen device in one direction without the help of a tool, and the exposed condenser can be directly cleaned, thereby shortening the cleaning time and promoting the depth and breadth of cleaning the condenser.

[0012] Preferably, the cab further comprises at least one clamping structure, the clamping structure comprises a first clamping part arranged on the lower shroud and a second clamping part arranged on the filter screen device, and the filter screen device is connected to the lower shroud through the clamping structure to fix the filter screen device to the lower shroud. Through the above scheme, the filter screen device is further fixed to prevent the filter screen from moving, and the problem of being difficult to disassemble or needing a tool is avoided.

[0013] Preferably, the filter screen device further comprises a filter screen body and a frame fixed to the filter screen peripheral part, the frame comprises a second connecting hole, and the filter screen is connected to the second connecting hole through a draw core rivet to fix the filter screen body to the frame. Compared with the structure without the frame, the strength of the filter screen device is improved.

[0014] Preferably, the filter screen device further comprises a hand holding part arranged on the edge of the frame and bent downward along the frame, and the hand holding part is used to facilitate opening of the filter screen device.

[0015] Preferably, the first clamping part comprises at least two clamping parts arranged in front of the through port close to the lower shroud, at least two clamping parts arranged behind the through port close to the lower shroud, and at least two clamping parts arranged on the right side of the lower shroud; the second clamping part is arranged below the frame, and the second clamping part comprises at least two clamping parts arranged in front of the frame, at least two clamping parts arranged behind the frame, and at least two clamping parts arranged on the right side of the frame.
