Description

Technical Field

[0001] The utility model relates to the technical field of wheeled tractors, in particular to a wheeled tractor cab top cover. Background Art

[0002] The maximum adhesion and anti-skidding ability between the driving wheels of a wheeled tractor and the ground is called the tractor's adhesion performance. If the adhesion performance is good and the skidding is light, the driving torque can be fully utilized, the capacity of the internal combustion engine can be fully utilized, and the tractor will appear powerful when working. In addition, wheeled tractors are often used in the agricultural field, which can effectively replace the bulky effects of old tractors, while facilitating the improvement of the driver's comfort and operating effect.

[0003] During driving of the existing wheeled tractor, although a plastic roof is provided on the top of the cab, the plastic roof will transfer heat to the cab in the hot summer. The ventilation effect of the driver by opening the window is very small, which can greatly reduce the efficiency of the driver in driving the wheeled tractor and also cause heat stroke. Since the driving roof is made of plastic, it will become powdery after long-term use. When encountering falling objects, it is easy to break and endanger the personal safety of the driver. In addition, when the wheeled tractor is driving on a bumpy road, the driving roof is easy to loosen and hit the driver's head, thereby increasing the safety hazard of the driver.

[0004] For this purpose, we designed a wheeled tractor cab roof. Utility Model Content

DETAILED DESCRIPTION

[0022] Reference Figure 1-Figure 4 A wheeled tractor cab roof comprises a roof body 1. The roof body 1 is the roof of the wheeled tractor cab in the prior art and is usually made of plastic material. The roof body 1 in this article is made of aluminum alloy material, which is light and has high strength, and can effectively replace plastic material. At the same time, aluminum alloy has fast thermal conductivity, which can effectively avoid heatstroke caused by high temperature in summer. The leading edge plate 2 is made of aluminum alloy material, which can extend the coverage area of ​​the front and rear ends of the roof body 1, and can effectively increase the control of the roof body 1 on the cab frame and reduce the generation of shaking. The outer fixing plates 3 are arranged on both sides of the roof body 1, which are fixing components and are fixed to the cab frame by rivet components.

[0023] The front plate 2 is provided with a plurality of shock-absorbing blocks 4 for alleviating driving bumps. The shock-absorbing blocks 4 are made of shock-absorbing materials and are helpful in dispersing the vibrations transmitted from the cab. The shock-absorbing blocks 4 are fixedly connected to the front plate 2 by fasteners. The fasteners are auxiliary connecting components, which are convenient for removing and replacing the shock-absorbing blocks 4. The front plate 2 is fixedly connected to the top cover body 1 by welding. Welding can provide a permanent connection effect and improve the connection strength. The outer fixing plate 3 is fixedly connected to the cab frame by rivets. Rivets are auxiliary tools for fixing existing metal components to each other.

[0024] The top cover body 1 is provided with a plurality of vents 5 for improving the air circulation in the cab. The vents 5 are provided at the top of the top cover body 1 and are opened toward the inner wall in a triangular shape, so that the top of the vents 5 is in a triangular slope shape, which is convenient for water to fall in and slide down in time. An air intake cavity 12 and an exhaust cavity 13 are provided in the vents 5. The air intake cavity 12 is connected with the vents 5, the exhaust cavity 13 is connected with the inner wall of the top cover body 1, and the exhaust cavity 13 is connected with the cab.

[0025] Shock-absorbing plates 6 for protecting the driver's head are symmetrically arranged on the top cover body 1. The shock-absorbing plates 6 are shock-absorbing components made of existing shock-absorbing materials, which are mainly used to protect the top of the cab. In order to improve the protection of the driver's head, a rubber buffer surface can be provided at the bottom of the shock-absorbing plate 6 to improve the impact buffering effect. The shock-absorbing plate 6 is connected to the top cover body 1. The shock-absorbing plate 6 is fixedly connected to the inner wall of the top cover body 1 by rivets. Leather edges 7 for improving the appearance are provided at both ends of the shock-absorbing plate 6. The leather edges 7 are mainly used to protect both sides of the shock-absorbing plate 6 to prevent the exposed position from being exposed to the air for a long time and aging, and are fixedly connected to the shock-absorbing plate 6 by fasteners, which are auxiliary fixing components.

[0026] The top cover body 1 is provided with a plurality of heat absorbing blocks 8 for alleviating the temperature of the cab. The heat absorbing blocks 8 are made of metal material and a heat absorbing coating is sprayed on the surface thereof, which can effectively improve the freshness of the cab. A sliding cavity is provided on the inner wall of the top cover body 1, which can facilitate the free adjustment of the heat absorbing blocks 8, and the heat absorbing blocks 8 are linearly arranged in the sliding cavity. There are a total of ten heat absorbing blocks 8, and the specific number needs to be set according to the specifications of the top cover body 1. A limiting groove is provided in the sliding cavity, and the heat absorbing blocks 8 slide in the limiting groove through a slider. The limiting groove is a slot for correcting the position of the heat absorbing blocks 8, and the slider is an auxiliary connecting sliding component.

[0027] A cushioning airbag 11 for improving impact resistance is provided in the top cover body 1. The cushioning airbag 11 is mainly used to improve the self-strength of the top cover body 1, and at the same time has a resistance effect to prevent falling objects from high altitude from directly penetrating the top cover body 1 and causing personal threat to the driver. An inner cavity 9 is symmetrically opened in the top cover body 1. The inner cavity 9 is opened inside the top cover body 1. A plurality of shock-absorbing columns 10 for improving the strength of the top cover body 1 are provided in the inner cavity 9. The shock-absorbing columns 10 are dampers in the prior art, which have strong impact resistance. The cushioning airbag 11 is tightly pressed against the inner wall of the inner cavity 9.

[0028] A water blocking plate 15 for reducing the backflow of rainwater is provided in the vent 5. The function of the water blocking plate 15 is to prevent water from backflowing into the cab from the vent 5 during rainy weather. One end of the water blocking plate 15 rotates in the air intake chamber 12 through an auxiliary shaft 14. The auxiliary shaft 14 is a control component of the water blocking plate 15, so that the water blocking plate 15 can be turned 45 degrees. The surface of the water blocking plate 15 is porous. When rainwater spreads, due to the air pressure in the exhaust chamber 13, the rainwater is organized in the air intake chamber 12 to form a water film, which can ensure that the backflow of external rainwater is reduced under the condition of air circulation. The auxiliary shaft 14 is fixedly connected to the inner wall of the air intake chamber 12 through a fastener. The fastener is an auxiliary component. The inner wall of the air intake chamber 12 is provided with a supporting block for lifting the water blocking plate 15. The supporting block is arranged at the other end of the air intake chamber 12, so that the tractor itself can be prevented from shaking in the state of the water blocking plate 15, resulting in the opening and closing of the water blocking plate 15.

[0029] The working principle of the utility model is as follows: the top cover body 1 is buckled on the cab frame, and the four corners of the outer fixing plate 3 are fixed to the frame by rivets. When the driver is driving, the vents 5 can effectively improve the air circulation in the cab and avoid the accumulation of heat on the top of the driver. When the tractor is driving in an area with many falling objects from high altitudes, after the falling objects hit the top cover body 1, the cushioning airbag 11 and the shock absorbing column 10 can effectively cushion the impact, while ensuring that the impact will not be directly transmitted to the shock absorbing plate 6, which can protect the driver's safety to the greatest extent.
