Description

Technical Field

[0001] This utility model relates to the field of cab technology, and in particular to cabs for bulldozers. Background Technology

[0002] A bulldozer is a self-propelled machine used for earthmoving projects. It mainly uses a pusher to excavate, transport, and dump soil and rock. During the operation of a bulldozer, a person needs to sit in the cab to operate the bulldozer.

[0003] Most existing bulldozer cabs are covered by transparent glass. However, in rainy weather, rainwater may hit the cab glass, causing a layer of water to form on the glass surface. This water layer can significantly obstruct the driver's vision and affect the driver's ability to operate the bulldozer normally. Utility Model Content

[0004] The technical problem this invention aims to solve is that in rainy weather, rainwater may hit the cab glass, causing a layer of water to form on the glass surface. This water layer significantly obstructs the driver's vision and affects the driver's normal operation of the bulldozer.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a bulldozer cab, comprising: a cab body, the cab body being used to carry the driver to operate the bulldozer; wherein the cab body is equipped with glass on all four sides to provide protection for the driver; and a rainproof assembly, the rainproof assembly being disposed on the top of the cab body, wherein the rainproof assembly is placed on the top of the cab body to block falling rainwater.

[0006] Preferably, the rainproof assembly includes: a perforated frame fixedly connected to the cab body, wherein a connecting seat is fixedly connected to the inner side of the perforated frame; a cable reel, wherein the cable reel is rotatably mounted on the connecting seat via a bearing, and wherein the cable reel is driven by a self-locking motor; a rainproof plate, wherein the rainproof plate is slidably mounted on the perforated frame via a spring frame, wherein the other end of the spring on the spring frame is fixedly connected to the perforated frame; and a rope fixedly connected between the cable reel and the spring frame, wherein when the rainproof plate is not in use, the rope is wound up on the cable reel.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up the rainproof component, when the bulldozer is operating in the rain, the self-locking motor is activated, causing the self-locking motor to drive the cable reel to rotate, causing the cable reel to release the rope wound on its surface. At this time, under the reaction force of the spring in the spring frame, the spring frame pushes the rainproof plate to move away from the hole frame. When the spring frame moves to the maximum position, the rainproof plate extends and is positioned above the cab body and glass to intercept rainwater, reducing the contact between rainwater and glass, thereby achieving rainproof protection for the glass. This reduces the situation where rainwater hits the glass of the cab body and forms a layer of rainwater, which would significantly obstruct the driver's vision and affect the driver's normal operation of the bulldozer, thus improving the safety and visibility of operations in rainy weather.

[0008] Preferably, the rainproof assembly further includes a deflector plate, wherein the deflector plate is fixed to the side of the rainproof plate away from the hole frame, and wherein the deflector plate is fixed at an angle.

[0009] The effect achieved by the above components is as follows: by setting the deflector, the deflector can expand the coverage area of ​​the rain shield, increase the interception effect of rainwater, and at the same time, it can use its own slope to guide the rainwater out, reducing the situation where rainwater flows back along the surface of the rain shield and comes into contact with the glass.

[0010] Preferably, the rainproof component further includes: reinforcing ribs, wherein the reinforcing ribs are uniformly fixed to the rainproof plate, and wherein the reinforcing ribs are made of stainless steel.

[0011] The effect achieved by the above components is that the strength of the rain shield can be increased by setting reinforcing ribs, and the deformation of the rain shield after being hit by debris can be reduced.

[0012] Preferably, the rainproof assembly further includes a reinforcing block, wherein the reinforcing block is fixed between the rope and the spring frame.

[0013] The effect achieved by the above-mentioned components is that the connection between the rope and the spring frame can be strengthened by setting the reinforcing block, reducing the possibility of the rope separating from the spring frame when it is pulled.

[0014] Preferably, the rainproof assembly further includes a support plate, wherein the support plate is fixed between the connecting seat and the hole frame, and wherein the surface of the support plate is trapezoidal.

[0015] The effect achieved by the above components is that by setting a support plate, the side of the connector seat near the hole frame can be supported and reinforced, reducing the up-and-down swaying of the connector seat when under force.

[0016] Preferably, it further includes: a protective component, the protective component comprising: a screw rod fixedly connected to the hole frame, wherein the surface of the screw rod is threaded with a threaded hole ring; a round hole block sleeved on the screw rod, wherein the round hole block is sleeved on the screw rod and fixed by compression through the threaded hole ring; and a protective cover fixedly connected to the round hole block, wherein the protective cover covers the upper part of the hole frame to protect the self-locking motor and the spring frame.

[0017] The effect achieved by the above components is as follows: By setting up the protective components, the protective cover is first moved manually to move the round hole block. When the round hole block moves to the position where it is fitted on the surface of the screw, the screw hole ring is manually rotated so that the screw hole ring moves up and down along the surface of the screw. The screw hole ring moves to the position where it presses against the surface of the round hole block to fix the round hole block and the protective cover. This allows the protective cover to cover the self-locking motor and the spring frame and protect them. This reduces the possibility of damage to the self-locking motor and the spring frame in the rainproof assembly after being hit by external debris, which could affect the normal driving of the rainproof plate and improve the safety of the self-locking motor and the spring frame.

[0018] Preferably, the surface of the screw hole ring is fixedly connected with a plurality of anti-slip strips, and the plurality of anti-slip strips are arranged at equal intervals.

[0019] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the screw ring can be increased, reducing the chance of slipping when manually turning the screw ring.

[0020] The beneficial effects of this utility model are:

[0021] By installing rain-blocking components, rainwater can be intercepted, preventing it from contacting the glass and reducing the amount of rainwater hitting the cab's glass and forming a layer of water that would significantly obstruct the driver's view and affect their ability to operate the bulldozer normally. This improves the safety and visibility of operations in rainy weather. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1-4 The bulldozer cab shown includes: a cab body 1, which carries the driver to operate the bulldozer; glass 2 is installed around the cab body 1 to provide protection for the driver; and a rain shield 3, which is located on the top of the cab body 1 to block falling rainwater.

[0031] Figure 2 and Figure 3The rain shield assembly 3 shown includes: a perforated frame 31, which is fixedly connected to the cab body 1, wherein a connecting seat 32 is fixedly connected to the inner side of the perforated frame 31; a cable reel 34, which is rotatably mounted on the connecting seat 32 via a bearing, and is driven by a self-locking motor; a rain shield 36, which is slidably mounted on the perforated frame 31 via a spring frame 35, wherein the other end of the spring on the spring frame 35 is fixedly connected to the perforated frame 31; and a rope 37, which is fixedly connected between the cable reel 34 and the spring frame 35. When the rain shield 36 is not in use, the rope 37 is wound up on the cable reel 34. By setting up the rain shield assembly 3, when the bulldozer is operating in rainy weather, the self-locking motor is activated, so that... The self-locking motor drives the winding rod 34 to rotate, causing the winding rod 34 to release the rope 37 wound on its surface. At this time, under the reaction force of the spring in the spring frame 35, the spring frame 35 pushes the rain shield 36 to move away from the hole frame 31. When the spring frame 35 moves to the maximum position, the rain shield 36 extends and is positioned above the cab body 1 and the glass 2 to intercept rainwater, reducing the contact between rainwater and glass 2, thereby achieving rain protection for glass 2. This reduces the amount of rainwater hitting the glass 2 of the cab body 1 and forming a layer of rainwater, which would significantly obstruct the driver's vision and affect the driver's normal operation of the bulldozer, thus improving the safety and visibility of operations in rainy weather.

[0032] Figure 2 and Figure 3 The rainproof assembly 3 also includes a deflector plate 38, which is fixed to the side of the rainproof plate 36 away from the hole frame 31. The deflector plate 38 is fixed at an angle. By setting the deflector plate 38, the coverage area of ​​the rainproof plate 36 can be expanded, increasing the interception effect of rainwater. At the same time, the slope of the deflector plate can be used to guide the rainwater, reducing the possibility of rainwater flowing back along the surface of the rainproof plate 36 and coming into contact with the glass 2. The rainproof assembly 3 also includes a reinforcing rib 39, which is uniformly fixed to the rainproof plate 36. The reinforcing rib 39 is made of stainless steel. By setting the reinforcing rib 39, the strength of the rainproof plate 36 can be increased, reducing the possibility of deformation of the rainproof plate 36 after being hit by debris.

[0033] Figure 2 and Figure 3The rainproof component 3 shown also includes a reinforcing block 310, which is fixed between the rope 37 and the spring frame 35. By setting the reinforcing block 310, the connection between the rope 37 and the spring frame 35 can be strengthened, reducing the possibility of the rope 37 separating from the spring frame 35 when it is pulled. The rainproof component 3 also includes a support plate 33, which is fixed between the connecting seat 32 and the hole frame 31. The surface of the support plate 33 is trapezoidal. By setting the support plate 33, the side of the connecting seat 32 near the hole frame 31 can be supported and reinforced, reducing the possibility of the connecting seat 32 swaying up and down when it is under force.

[0034] Figure 3 and Figure 4 The diagram also includes: a protective component 4, comprising: a screw 41 fixedly connected to the hole frame 31, wherein the surface of the screw 41 is threadedly connected to a threaded hole ring 42; a round hole block 43 fitted onto the screw 41, wherein the round hole block 43 is fitted onto the screw 41 and fixed by compression through the threaded hole ring 42; and a protective cover 44 fixedly connected to the round hole block 43, wherein the protective cover 44 covers the upper part of the hole frame 31 to protect the self-locking motor and the spring frame 35. By setting the protective component 4, the protective cover 44 is first manually moved to drive the round hole... When block 43 moves, and the round hole block 43 moves to the position where it fits on the surface of screw 41, the screw hole ring 42 is manually rotated, so that the screw hole ring 42 moves up and down along the surface of screw 41, so that the screw hole ring 42 moves to the position where it presses the surface of the round hole block 43 to fix the round hole block 43 and the protective cover 44. This allows the protective cover 44 to cover the self-locking motor and spring frame 35 and protect them, reducing the possibility of damage to the self-locking motor and spring frame 35 in the rainproof assembly 3 after being hit by external debris, which would affect the normal driving of the rainproof plate 36 and improve the safety of the self-locking motor and spring frame 35.

[0035] Figure 3 and Figure 4 The screw hole ring 42 shown has multiple anti-slip strips fixedly connected to its surface. The anti-slip strips are arranged at equal intervals. By setting the anti-slip strips, the friction between the hand and the screw hole ring 42 can be increased, reducing the possibility of slipping when manually rotating the screw hole ring 42.

[0036] Working principle: When the bulldozer is operating in the rain, the self-locking motor is started, which drives the cable reel 34 to rotate, causing the cable reel 34 to release the rope 37 wrapped on its surface. At this time, under the reaction force of the spring in the spring frame 35, the spring frame 35 pushes the rain shield 36 to move away from the hole frame 31. When the spring frame 35 moves to the maximum position, the rain shield 36 extends and is positioned above the cab body 1 and the glass 2 to intercept rainwater, reducing the contact between rainwater and the glass 2, thereby achieving rain protection for the glass 2.

[0037] First, manually move the protective cover 44 to move the round hole block 43. When the round hole block 43 moves to the position where it is fitted on the surface of the screw 41, manually rotate the screw hole ring 42 so that the screw hole ring 42 moves up and down along the surface of the screw 41. This moves the screw hole ring 42 to the position where it presses the surface of the round hole block 43 and fixes the round hole block 43 and the protective cover 44. This allows the protective cover 44 to cover and wrap the self-locking motor and the spring frame 35, thereby protecting the self-locking motor and the spring frame 35.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
