Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a laminated glass cab for a corn harvester. Background Art

[0002] The corn harvester glass cab frame is the basic structure of the entire cab, which provides the necessary support so that the cab can be firmly installed on the corn harvester. The frame structure can protect the internal equipment from external impact and damage, and also provide a certain degree of safety protection for the driver.

[0003] When a corn harvester is operating, corn dust and dirt that enter the frame can adhere to the cab glass, reducing transparency, affecting the driver's vision and harvesting efficiency. The microorganisms, allergens, and other harmful substances contained in these materials pose health risks. Long-term inhalation can easily lead to respiratory diseases, coughs, and asthma, and irritate the skin and eyes, causing redness, swelling, and itching. Furthermore, current agricultural machinery glass is cut from a single piece of glass, which has poor impact resistance. It easily breaks completely when struck by stones or thick branches. These foreign objects can injure occupants in the cab, not to mention the potential for shattered glass fragments to injure the operator, rendering it ineffective in protecting the operator inside. Utility Model Content

[0004] The utility model discloses a laminated glass cab for a corn harvester, which aims to solve the problem that when the corn harvester is working, corn crumbs and dust entering the frame will adhere to the cab glass, affecting the driver's vision and harvesting efficiency, and also endangering health. Long-term inhalation of the dust can easily lead to various diseases. It also aims to solve the problem that the cab has insufficient violence strength and the driver is easily injured when hit by foreign objects.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The laminated glass cab of a corn machine includes a cab frame, a dust suction component is provided on the inner side of the cab frame, the dust suction component includes a fan drive motor, the outer side of the fan drive motor is fixedly connected to a motor frame 1, and the power output shaft of the fan drive motor is connected to a rotating part through a bearing transmission, the front end of the rotating part is fixedly connected to a fan blade, the front end of the fan blade is provided with a cotton cloth plate, the front end of the cotton cloth plate is fixedly connected to a filter plate, and the front end of the filter plate is fixedly connected to a dust suction pipe, the front end of the dust suction pipe is fixedly connected to a dust suction port, the rear side of the fan drive motor is provided with an air inlet pipe, the inner side of the front end of the air inlet pipe is fixedly connected to the air inlet plate, and the air inlet pipe and the air inlet plate are both located inside the cab frame, a windshield is installed on the cab frame, the windshield is a laminated double-layer glass, and the windshield has an arc-shaped convex surface convex to the outside.

[0007] In a preferred solution, the windshield has double-curved glass, and the double-curved surface of the windshield is composed of two circular arcs with different radii.

[0008] In a preferred embodiment, the arc radius on the vertical section of the windshield is 4500-5500 mm, and the arc length is 1250-1550 mm; the arc radius on the horizontal section of the windshield is 2000-3500 mm, and the arc length is 1550-1850 mm.

[0009] As a specific preferred embodiment, the arc radius of the windshield's vertical cross-section is 4930mm, and the arc length is 1420mm; the arc radius of the windshield's horizontal cross-section is 2500mm, and the arc length is 1720mm. Double-curved laminated glass, particularly the combination of this radius and arc, allows for optimal viewing angles while maintaining high damage resistance. This is particularly true when struck by unexpected foreign objects such as tree branches, providing excellent puncture resistance and mitigating subsequent damage. Furthermore, it prevents glass from breaking into shattered fragments and causing injury, significantly enhancing the safety of those in the cab.

[0010] By providing a cab frame and a dust collection component, when the corn harvester is working, the fan drive motor is started, and the fan blades are driven to rotate through the rotating parts, and the outside air enters the interior of the dust collection shell through the dust collection port. The dust and corn crumbs in the air are intercepted by the filter plate and the cotton cloth plate to avoid entering the interior of the dust collection shell. The filtered air enters the interior of the cab frame through the air inlet plate fixedly connected to the air inlet pipe. During the process, the dust collection component sends the filtered air into the interior of the corn harvester frame, which can effectively reduce internal dust accumulation, prevent dust from affecting the normal operation of the harvester's mechanical parts, reduce the probability of failure caused by dust, and extend the service life of the equipment. At the same time, it can maintain a good working environment, provide a relatively clean space for operators, reduce the harm of dust to the human body, and improve the comfort and safety of operation.

[0011] In a preferred solution, the bottom end of the motor frame 1 is fixedly connected to a dust suction shell, the inner side of the dust suction shell is fixedly connected to the outer side of the cotton cloth plate and the filter plate, and the front end of the dust suction shell is fixedly connected to the bottom end of the air inlet pipe, and the bottom end of the dust suction shell is fixedly connected to the front end of the dust suction pipe. A rectangular hole is provided on the rear side of the cab frame, and the inner side of the rectangular hole is fixedly connected to the outer side of the dust suction shell. A circular hole is provided at the bottom end of the dust suction pipe, and the inside of the circular hole is fixedly connected to a dust collection box, and the inside of the dust collection box is fixedly connected to a connecting seat, and the inner side of the connecting seat is fixedly connected to a connecting rod 2, and the front end of the connecting rod 2 is movably connected to the connecting rod 1, and a spring rope is fixedly connected between the connecting rod 1 and the connecting rod 2, and the front end of the connecting rod 1 is fixedly connected to a movable plate, and both sides of the cab frame are fixedly connected to door panels, and both sides of the cab frame are fixedly connected to armrests.

[0012] By providing a dust collection shell, a dust collection box, a connecting seat, a second connecting rod, a first connecting rod, a movable plate, a door panel and an armrest, when the corn machine is working, the debris and dust filtered by the dust collection component enter the dust collection box through the circular hole at the bottom of the dust collection tube, and the debris and dust fall onto the movable plate. After accumulating too much, the connecting rod is driven downward by gravity, and the debris and dust fall to the bottom of the dust collection box, and the movable plate is driven to return to its original position by the elastic action of the spring rope.

[0013] The cam is connected to the bottom of the cam by a movable rod, and the movable rod is connected to the bottom of the cam by a movable rod.

[0014] By providing an opening and closing assembly, when the debris and dust inside the dust box accumulate to a certain amount, the servo motor is started to drive the rotating rod to rotate, and at the same time the movable rod on the outside of the rotating rod drives the opening and closing door fixedly connected to the connecting rod to move downward, and the debris and dust inside the dust box fall into the air, and then the servo motor drives the opening and closing door to close. During the process, excessive accumulation of dust and debris will reduce the effective volume of the dust box. The opening and closing assembly can be cleaned in time to ensure its normal dust suction ability, allowing the dust suction assembly to continue to operate efficiently, ensuring that all components of the corn machine work in a good environment.

[0015] From the above, the beneficial effects of the present application can be seen. The corn harvester laminated glass cab provided by the present invention has a dust collection component that sends filtered air into the interior of the corn harvester frame, which can effectively reduce internal dust accumulation, prevent dust from affecting the normal operation of the harvester's mechanical parts, reduce the probability of failure due to dust, and extend the service life of the equipment. At the same time, it can maintain a good working environment, provide a relatively clean space for operators, reduce the harm of dust to the human body, and improve the comfort and safety of operation. The present application adopts double-curved laminated glass, especially the combination under specific radius and curvature, which can make the double-sided laminated glass achieve the best viewing angle while having extremely high damage resistance. Especially when accidentally hit by foreign objects such as branches, it can not only play an excellent anti-puncture resistance effect, but also reduce the damage after puncture, and can avoid the situation where the glass is broken into fragments and hurts people after puncture and impact, greatly increasing the personal safety of people in the cab.
