Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a self-protecting dozer blade for impacting stones comprises a base plate 1, a certain gap is formed between the base plate 1 and a dozer plate 14 to prevent the base plate 1 from being locked with the dozer plate 14 when deflecting, a blade head 2 is inserted into the right side of the base plate 1, an extrusion rod 3 is fixedly connected to the left side of the blade head 2, an extrusion plate 4 is fixedly connected to the bottom of the blade head 2, a limit rod 5 is arranged on the left side of the extrusion plate 4, a power storage rod 6 is rotatably connected to the right side of the limit rod 5, a limit spring is arranged inside the power storage rod 6 to store power for moving the extrusion plate 4, a roller 7 is rotatably connected to the bottom of the power storage rod 6, the roller 7 is initially positioned on the leftmost side of a surface chute of a limit block 8, so that when the extrusion plate 4 resets to extrude the limit rod 5 leftwards, the roller 7 slides rightwards in the chute and cannot block the extrusion plate 4 any more, a limit block, a transmission rod 9 is arranged on the left side of the limiting rod 5, a receiving gear 10 is rotatably connected on the left side of the transmission rod 9, a clockwork spring ring is arranged inside the receiving gear 10, a supporting roller 16 restores to an initial position when the shovel head 2 automatically rotates reversely when resetting, an arc plate 11 is engaged and connected on the surface of the receiving gear 10, a supporting wheel 12 is rotatably connected on the bottom of the arc plate 11, a soil retaining plate 13 is rotatably connected on the left side of the bottom plate 1, a soil pushing plate 14 is slidably connected on the side surface of the soil retaining plate 13, a fixing rod 15 is inserted and arranged on the right side of the soil pushing plate 14, a supporting roller 16 is rotatably connected on the surface of the fixing rod 15, a hinge rod 17 is inserted and arranged on the left side of the bottom plate 1 and above the soil retaining plate 13, a spiral wheel 18 is fixedly connected on the right side of the hinge rod 17 through a connecting, the surface of the helical wheel 18 is connected with a sliding ball 20 in a sliding way, the surface of the sliding ball 20 is provided with a push rod 19, and the push rod 19 is fixedly connected with the extrusion rod 3 through a connecting rod.

The working principle is that when the bulldozer works, the bottom plate 1 drives the shovel head 2 to be inserted into soil, when the shovel head 2 is extruded with a stone, the shovel head 2 can move leftwards relative to the bottom plate 1 under the action of extrusion force, the extrusion plate 4 on the lower surface of the shovel head can be blocked by the limiting rod 5, and the limiting rod 5 can stretch the limiting spring arranged inside the force storage rod 6 along with the increase of the extrusion force of the extrusion plate 4 on the limiting rod 5.

When the limiting spring is stretched to a certain degree, the extrusion plate 4 can move to the left side by passing over the limiting rod 5 to extrude the transmission rod 9, the transmission rod 9 moves to the left side in the bottom plate 1 to drive the receiving gear 10 to rotate anticlockwise to drive the arc plate 11 meshed with the transmission rod, so that the supporting wheel 12 at the bottom of the arc plate 11 moves downwards and extrudes the ground, further the bottom plate 1 generates upward deflection force, a certain gap exists between the bottom plate 1 and the soil shifting plate 14 and the supporting wheel is connected with the fixing rod 15, therefore, when the bottom plate 1 generates upward deflection force, the bottom plate 1 drives the fixing rod 15 to rotate in the soil shifting plate 14 through the supporting roller 16, namely, the bottom plate 1 drives the shovel head 2 to tilt upwards, the shovel head 2 slides on the surface of the stone instead of continuously extruding the stone, so that the extrusion force between the shovel head 2 and the stone cannot be continuously increased, thereby achieving the purpose that when the soil shifting shovel strikes the stone, the automatic force unloading prevents the damage of the 2 parts of the bulldozer shovel head.

When the stripper plate 4 did not cross gag lever post 5, shovel head 2 can continuously drive the squeeze bar 3 and remove for bottom plate 1 left, because squeeze bar 3 passes through connecting rod synchronous motion with push rod 19, so push rod 19 can drive sliding ball 20 and slide in the inclined groove that helical wheel 18 surface was seted up, so helical wheel 18 rotates, and then drive left hinge lever 17 and rotate, because hinge lever 17 inserts in the space between bottom plate 1 and the bull blade 14, so along with hinge lever 17 rotates, bottom plate 1 and bull blade 14 soil up to now can be taken out bottom plate 1 surface along with the rotation of hinge lever 17, thereby reached and avoided there being soil between the two to cause the effect of resistance when bottom plate 1 deflects for bull blade 14.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
