Description

Technical Field

[0001] The present invention relates to the technical field of snow shoveling, and more particularly to a snow shoveling mechanism applicable to different road surfaces. Background Art

[0002] Snow accumulation in yards and roads due to snowfall causes inconvenience in people's transportation and activities. Snow removal using shovels and brooms is too inefficient, and snow removal on main roads is generally done by snow removal equipment. Snowplows are widely used to remove snow on roads. Snowplows usually include a snowplow body and a snowplow mechanism provided on the snowplow body.

[0003] Existing snow shovel mechanisms are usually designed in a relatively simple manner and are difficult to adapt to a variety of road conditions. On different types of roads, such as urban roads, rural roads, and highways, snow shovel mechanisms need to have different working capabilities and flexibility. Some snow shovel mechanisms may cause damage to the road surface during operation. At the same time, if the snow is too hard or uneven, it will cause serious damage to the snow shovel mechanism itself, especially its hydraulic mechanism and blade. Therefore, it is necessary to design a snow shovel mechanism that can be applied to different road conditions to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a snow shoveling mechanism that can be applied to different road surfaces. On the basis of realizing snow shoveling on the road surface, the present invention can also adjust the snow shoveling angle of the snow shoveling bucket according to different road surfaces, and can perform rebound protection when contacting hard objects.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A snow shoveling mechanism applicable to different road surfaces, comprising a mounting assembly for connecting to a snow shoveling vehicle body, a connecting assembly arranged on the mounting assembly, a rotating shaft arranged on the connecting assembly, two sets of snow shoveling assemblies rotatably connected to the rotating shaft and symmetrically arranged on the left and right, and a first supporting oil cylinder and a second supporting oil cylinder hinged between the corresponding snow shoveling assemblies and the connecting assembly and respectively driving the corresponding snow shoveling assemblies to swing;

[0007] The connecting assembly is also provided with a control valve body for controlling the operation of the first supporting oil cylinder and the second supporting oil cylinder and providing buffer protection for the first supporting oil cylinder and the second supporting oil cylinder; the control valve body is provided with a solenoid valve SV1, a solenoid valve SV2, a relief valve RV1, a relief valve RV2, a relief valve RV3 and a one-way valve CV1; the control valve body is provided with an oil port A and an oil port B connected to an external oil supply system;

[0008] The oil circuit formed by the oil port A, the solenoid valve SV1, the oil port A1 of the barrel of the first supporting oil cylinder, the oil port A2 of the piston barrel of the first supporting oil cylinder, the oil port B2 of the piston barrel of the second supporting oil cylinder, the oil port B1 of the barrel of the second supporting oil cylinder, the solenoid valve SV2 and the oil port B through pipeline connection controls the operation of the first supporting oil cylinder and the second supporting oil cylinder;

[0009] The oil circuit formed by connecting the oil port A1 of the first supporting oil cylinder barrel, the relief valve RV1, the one-way valve CV1, the relief valve RV3, and the oil port A2 of the first supporting oil cylinder piston barrel through pipelines provides buffer protection for the first supporting oil cylinder;

[0010] The oil circuit formed by connecting the oil port B1 of the second supporting oil cylinder barrel, the relief valve RV2, the one-way valve CV1, the relief valve RV3, and the oil port B2 of the second supporting oil cylinder piston barrel through pipelines provides buffer protection for the second supporting oil cylinder.

[0011] The connection assembly is also provided with a cache mechanism, which includes a diaphragm accumulator. The diaphragm accumulator is divided into two upper and lower chambers. The upper chamber is filled with inert gas, and the lower chamber is connected to an oil port T. The oil port T is respectively connected to the overflow valve RV1, the overflow valve RV2 and the one-way valve CV1 through pipelines.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] 1. The present invention can control the operation of the first supporting oil cylinder and the second supporting oil cylinder through the control valve body, and can also provide buffer protection for the first supporting oil cylinder and the second supporting oil cylinder to prevent the first supporting oil cylinder and the second supporting oil cylinder from being damaged by the instantaneous retraction of the snow shoveling assembly when the snow shoveling assembly encounters a hard and uneven roadside. In addition, the present invention can adjust the snow shoveling angle and opening size of the snow shoveling assembly through the connecting assembly, the first supporting oil cylinder and the second supporting oil cylinder, and can automatically adjust the snow shoveling angle and force according to the characteristics of different road surfaces, and is suitable for various road conditions such as urban roads, rural roads, and highways, and can meet the needs of different scenarios.

[0014] 2. The present invention provides a snow shoveling assembly. When the snow shoveling assembly contacts a hard object, the first supporting oil cylinder and the second supporting oil cylinder will control the snow shoveling assembly to avoid damage to the road surface. At the same time, the snow shoveling assembly can automatically avoid obstacles when encountering obstacles, reducing scratches and wear on the road surface. Under the coordinated action of the snow shoveling assembly, the control valve body, the buffer mechanism, the first supporting oil cylinder and the second supporting oil cylinder, not only the road surface is protected, but also the damage risk of the snow shoveling mechanism is reduced, the service life of the equipment is extended, and when encountering a hard object, it will automatically buffer, reduce the impact force on the driver, and improve driving safety.

[0015] 3. The present invention can install the mechanism on the surface of the snowplow body through the installation component. Through the damper on the installation component and the connecting plate slidably arranged on the installation rear frame, the entire connecting component can slide up and down. When the snowplow assembly encounters an uneven road surface, the snowplow assembly can slide up and down and has a certain up and down movement space, so as to further protect the snowplow assembly.

[0016] 4. The blade mounting seat of the present invention is connected to the bucket weldment through a buffer module, so that the straight blade on the blade mounting seat can buffer up and down when encountering an uneven road surface.

[0017] 5. The present invention can support the entire snow-clearing mechanism by providing a support module; when the snow-clearing mechanism is removed from the snow-clearing vehicle body, it can be supported by the support module to improve its stability.

[0018] 6. The present invention can also provide an ice-melting mechanism on the straight blade plate. By continuously increasing the temperature of the inner side of the side protection frame, the temperature of the side inclined baffle plate will be increased. The material of the side inclined baffle plate is a metal with high heat transfer efficiency. When the bucket body is shoveling snow, the snow will accumulate on one side of the blade mounting seat due to gravity, and will be accumulated due to the pressure of the gravity of the upper snow. At this time, the ice and snow on one side of the blade mounting seat will be continuously melted by the continuously heated side inclined baffle plate, and the melted liquid will flow along the liquid guide groove. The setting of the ice-melting mechanism can improve the efficiency of the snow shoveling process, and at the same time avoid the situation where more snow is compacted by gravity and attached to one side of the bucket, thereby improving the practicability of snow shoveling.

[0019] 7. The present invention continuously stirs the compacted snow or ice accumulated on one side of the blade mounting seat by means of rotating ice-breaking blade teeth, thereby crushing the ice and preventing the compacted snow from accumulating. Meanwhile, the top transmission rod is made of metal with high heat transfer efficiency, and the top transmission rod heats up as the heater is started, thereby improving the efficiency of snow melting and snow removal.

[0051] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0052] Embodiment 1:

[0053] like Figure 1 and 23 Shown is a schematic diagram of a snow shoveling mechanism provided by the present invention that is applicable to different road surfaces.

[0054] The snow shoveling mechanism applicable to different road surfaces comprises a mounting assembly 1 for connecting to a snow shoveling vehicle body, a connecting assembly 2 arranged on the mounting assembly 1, a rotating shaft 4 arranged on the connecting assembly 2, two sets of snow shoveling assemblies 3 rotatably connected to the rotating shaft 4 and symmetrically arranged on the left and right, and a first supporting oil cylinder 9 and a second supporting oil cylinder 901 hinged between the corresponding snow shoveling assemblies 3 and the connecting assembly 2 and respectively driving the corresponding snow shoveling assemblies 3 to swing;

[0055] The connecting assembly 2 is also provided with a control valve body 8 for controlling the operation of the first supporting oil cylinder 9 and the second supporting oil cylinder 901 and providing buffer protection for the first supporting oil cylinder 9 and the second supporting oil cylinder 901; the control valve body 8 is provided with a solenoid valve SV1805, a solenoid valve SV2806, a relief valve RV1801, a relief valve RV2802, a relief valve RV3803 and a one-way valve CV1804; the control valve body 8 is provided with an oil port A and an oil port B connected to an external oil supply system (the oil supply system can be a hydraulic oil supply system on the snowplow body);

[0056] The oil circuit formed by the oil port A, the solenoid valve SV1805, the oil port A1 of the cylinder barrel of the first supporting oil cylinder 9, the oil port A2 of the piston barrel of the first supporting oil cylinder 9, the oil port B2 of the piston barrel of the second supporting oil cylinder 901, the oil port B1 of the cylinder barrel of the second supporting oil cylinder 901, the solenoid valve SV2806 and the oil port B through pipeline connection controls the operation of the first supporting oil cylinder 9 and the second supporting oil cylinder 901;

[0057] The oil circuit formed by connecting the oil port A1 of the cylinder barrel of the first supporting oil cylinder 9, the relief valve RV1801, the one-way valve CV1804, the relief valve RV3803, and the oil port A2 of the piston cylinder of the first supporting oil cylinder 9 through pipelines provides buffer protection for the first supporting oil cylinder 9;

[0058] The oil circuit formed by connecting the oil port B1 of the cylinder barrel of the second supporting oil cylinder 901, the relief valve RV2802, the one-way valve CV1804, the relief valve RV3803, and the oil port B2 of the piston cylinder of the second supporting oil cylinder 901 through pipelines provides buffer protection for the second supporting oil cylinder 901.

[0059] The connecting component 2 is also provided with a cache mechanism, which includes a diaphragm accumulator 204. The diaphragm accumulator 204 is divided into two upper and lower chambers. The upper chamber is filled with inert gas, and the lower chamber is connected to an oil port T. The oil port T is respectively connected to the overflow valve RV1801, the overflow valve RV2802 and the one-way valve CV1804 through pipelines.

[0060] The present invention can install the mechanism on the snowplow vehicle body through the installation component 1, and the snowplowing angle and opening size of the snowplowing component 3 can be adjusted through the connection component 2, the first supporting oil cylinder 9 and the second supporting oil cylinder 901. The snowplowing angle and force can be automatically adjusted according to the characteristics of different road surfaces, and it is suitable for various road conditions such as urban roads, rural roads, and highways, and can meet the needs of different scenes. In addition, when the snowplowing component 3 contacts a hard object, the control valve body 8 and the supporting oil cylinder will rebound the snowplowing component 3 to avoid damage to the road surface. At the same time, under the cooperation of the snowplowing component 3, the control valve body 8, the buffer mechanism and the first supporting oil cylinder 9 and the second supporting oil cylinder 901, not only the road surface is protected, but also the risk of damage to the snowplowing mechanism can be reduced, the service life of the equipment can be extended, and it will automatically rebound when encountering a hard object, reducing the impact force on the driver and improving driving safety.

[0061] like Fig.17As shown: when the snow shoveling assembly 3 connected to the first supporting oil cylinder 9 is hit, the first supporting oil cylinder 9 will retract, and the oil inside the first supporting oil cylinder 9 moves according to the gray arrow. The oil in the cylinder barrel of the first supporting oil cylinder 9 enters the overflow valve RV1801 along the oil port A1, and then enters the diaphragm accumulator 204 in the upper buffer mechanism and the one-way valve CV1804 on the lower side respectively. The diaphragm accumulator 204 is provided with two chambers, with a diaphragm in the middle, and nitrogen is filled in the upper side with an air pressure of 50 bar. When the oil enters the lower part of the diaphragm accumulator 204 from the T oil port, the diaphragm will be squeezed upward to compress the inert gas such as nitrogen filled, thereby buffering the flow rate of the oil, so as to control the retraction rate of the first supporting oil cylinder 9, thereby playing the first buffering role for the first supporting oil cylinder 9 and the snow shoveling assembly 3. At the same time, the oil will also enter the one-way valve CV1804, and the oil cannot flow back through the one-way valve CV1804, and is divided into two streams again. One stream of oil flows into the overflow valve RV3803, and the other stream of oil returns to the piston cylinder of the first supporting oil cylinder 9 through the A2 oil port to keep the oil pressure in the first supporting oil cylinder 9 stable; the overflow valve RV3803 is connected to the one-way valve CV1804, and the oil entering the one-way valve CV1804 will enter the overflow valve RV3803, but cannot flow back to the overflow valve RV1801 from the one-way valve CV1804. In this way, when the first supporting oil cylinder 9 retracts, the oil passes through the diaphragm accumulator 204 for the first buffering, and then passes through the one-way valve CV1804 for the second diversion and buffering again. At the same time, the oil returns to the piston cylinder of the first supporting oil cylinder 9, which can also effectively protect the first supporting oil cylinder 9 and is not easy to cause damage to the first supporting oil cylinder 9. Similarly, when the second supporting oil cylinder 901 encounters another snow shoveling component 3 and is hit, it retracts, and the oil circulation method is the same as that of the first supporting oil cylinder 9, which will not be elaborated here.

[0062] Under the action of the external oil supply system, the control valve body 8 controls the operation of the first supporting oil cylinder 9 and the second supporting oil cylinder 901 as follows, wherein the solenoid valve SV1805 and the solenoid valve SV2806 control the operation of the two oil cylinders through the oil port A and the oil port B respectively;

[0063] When the first supporting oil cylinder 9 is controlled to be stationary and the second supporting oil cylinder 901 is retracted, oil is introduced into the oil port A and oil is returned to the oil port B. The solenoid valve SV1805 is not energized, and the solenoid valve SV2806 is not energized. Fig.18 As shown;

[0064] When the first supporting oil cylinder 9 is controlled to be stationary and the second supporting oil cylinder 901 is extended, oil port A returns oil and oil port B enters oil, the solenoid valve SV1805 is not energized, and the solenoid valve SV2806 is not energized. Fig.19 As shown;

[0065] When the first supporting oil cylinder 9 is extended and the second supporting oil cylinder 901 is retracted, oil enters port A and oil returns to port B, solenoid valve SV1805 is energized, and solenoid valve SV2806 is not energized. Fig. 20 As shown;

[0066] When the first supporting oil cylinder 9 is controlled to retract and the second supporting oil cylinder 901 is extended, oil returns from oil port A and oil enters oil port B, solenoid valve SV1805 is energized, and solenoid valve SV2806 is not energized. Fig.21 As shown;

[0067] When the first supporting oil cylinder 9 is controlled to retract and the second supporting oil cylinder 901 is immobile, oil enters port A and oil returns to port B, the solenoid valve SV1805 is not energized, and the solenoid valve SV2806 is energized. Fig. 22 As shown;

[0068] When the first supporting oil cylinder 9 is controlled to extend and the second supporting oil cylinder 901 is immobile, oil port A returns oil and oil port B enters oil, the solenoid valve SV1805 is not energized, and the solenoid valve SV2806 is energized. Fig.23 shown.

[0073] The connecting assembly 2 includes a connecting plate 206 slidably disposed on the mounting rear frame 101 , the front cover connecting frame 112 is connected to the connecting plate 206 , a slider 2061 is disposed on the connecting plate 206 , and the slider 2061 is slidably disposed in the connecting slide groove 108 .

[0074] The connecting plate 206 is provided with a slot hole 2062 for mounting the slider 2061 .

[0075] In order to make the entire mounting assembly 1 form a whole, two first plastic wear-resistant plates 105 are fixedly connected to the surface of the mounting rear frame 101, a second plastic wear-resistant plate 106 is fixedly connected to the surface of the first plastic wear-resistant plate 105, and a slider pad 107 is fixedly connected to the surface of the second plastic wear-resistant plate 106;

[0076] In a specific embodiment of the present invention, the rear frame 101 is installed on the snowplow body using the orifice plate 102 and / or the support hook 103. When the snowplow assembly 3 is subjected to external force, the damper 104 expands and contracts, and the slider 2061 of the connecting plate 206 slides longitudinally along the connecting slide groove 108. Under the action of the damper 104, the connecting plate 206 can slide up and down, and at the same time, the connecting frame weldment 201 can have a shock-absorbing effect. The damper 104 can realize that the connecting assembly 2 and the snowplow assembly 3 have a certain activity space in the up and down directions, and can adapt to different road environments. The first plastic wear-resistant plate 105, the second plastic wear-resistant plate 106 and the slider pad 107 can protect the rear frame 101, thereby increasing the service life.

[0078] When the snow shoveling assembly 3 swings backward around the rotating shaft 4 , the snow shoveling assembly 3 contacts the rubber buffer rod 205 , and the rubber buffer rod 205 can elastically buffer and limit the snow shoveling assembly 3 .

When the snow shoveling component 3 encounters a hard object, the first supporting cylinder 9 or the second supporting cylinder 901 will be compressed. At this time, the hydraulic oil inside the first supporting cylinder 9 or the second supporting cylinder 901 will enter the interior of the diaphragm accumulator 204 through the control valve body 8 or buffer through other oil circuits, thereby buffering the first supporting cylinder 9 or the second supporting cylinder 901 and protecting the corresponding cylinders. At the same time, the rubber buffer rod 205 can elastically buffer and limit the snow shoveling component 3 from both sides, thereby reducing the probability of the snow shoveling component 3 bending from the surface of the rotating shaft 4.
