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] Due to snowfall, the yards and roads are covered with snow, which causes inconvenience to people's transportation and activities. The methods of removing snow with shovels and brooms are too inefficient. The snow removal work on main roads is generally completed by snow removal equipment. Snow plows are widely used for clearing snow on road surfaces. A snow plow usually includes a snow plow vehicle body and a snow shoveling mechanism provided on the snow plow vehicle body.

[0003] The existing snow shoveling mechanisms are usually designed in a relatively single way and are difficult to adapt to various road surface conditions. On different types of road surfaces such as urban roads, rural roads, highways, etc., the snow shoveling mechanism needs to have different working capabilities and flexibility. Some snow shoveling mechanisms may cause damage to the road surface during operation. At the same time, due to the hard or uneven snow, it will cause heavy damage to the snow shoveling mechanism itself, especially its hydraulic mechanism and blade plate. Therefore, it is necessary to design a snow shoveling mechanism applicable to different road surface conditions to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a snow shoveling mechanism applicable 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 shovel bucket according to different road surfaces and can perform rebound protection when contacting hard objects.

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

[0006] A snow shoveling mechanism applicable to different road surfaces, which includes a mounting component for connecting with a snow plow vehicle body, a connecting component provided on the mounting component, a rotating shaft provided on the connecting component, two groups of snow shoveling components rotatably connected to the rotating shaft and symmetrically arranged left and right, and a first support oil cylinder and a second support oil cylinder respectively driving the corresponding snow shoveling components to swing and hinged between the corresponding snow shoveling components and the connecting component;

[0007] A control valve body for controlling the operation of the first support oil cylinder and the second support oil cylinder and buffering and protecting the first support oil cylinder and the second support oil cylinder is further provided on the connecting component; an electromagnetic valve SV1, an electromagnetic valve SV2, a relief valve RV1, a relief valve RV2, a relief valve RV3 and a check valve CV1 are provided on the control valve body; an oil port A and an oil port B connected to an external oil supply system are provided on the control valve body;

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

[0009] The oil circuit formed by connecting the oil port A1 of the first support cylinder barrel, the relief valve RV1, the check valve CV1, the relief valve RV3, and the oil port A2 of the first support cylinder piston cylinder body through pipelines buffers and protects the first support cylinder;

[0010] The oil circuit formed by connecting the oil port B1 of the second support cylinder barrel, the relief valve RV2, the check valve CV1, the relief valve RV3, and the oil port B2 of the second support cylinder piston cylinder body through pipelines buffers and protects the second support cylinder.

[0011] A buffer mechanism is further provided on the connection assembly. The buffer mechanism includes a diaphragm accumulator. The diaphragm accumulator is divided into upper and lower chambers. The upper chamber is filled with inert gas. An oil port T is communicated with the upper part of the lower chamber. The oil port T is connected to the relief valve RV1, the relief valve RV2, and the check valve CV1 through pipelines respectively.

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

[0013] 1. The present invention can control the operation of the first support cylinder and the second support cylinder through the control valve body, and can buffer and protect the first support cylinder and the second support cylinder at the same time, preventing damage to the first support cylinder and the second support cylinder caused by the instantaneous retraction of the first support cylinder and the second support cylinder when the snow plowing assembly encounters a hard and uneven roadside. In addition, the present invention can adjust the snow plowing angle and the opening size of the snow plowing assembly through the connection assembly, the first support cylinder and the second support cylinder, and can automatically adjust the snow plowing angle and force according to the characteristics of different road surfaces, is applicable to various road surface conditions such as urban roads, rural roads, and highways, and can meet the requirements of different scenarios at the same time.

[0014] 2. Through the setting of the snow plowing assembly, when the snow plowing assembly contacts a hard object, the first support cylinder and the second support cylinder will control the snow plowing assembly to avoid damaging the road surface. At the same time, the snow plowing assembly can automatically avoid obstacles when encountering obstacles, reducing the scraping and wear of the road surface. Under the combined action of the snow plowing assembly, the control valve body, the buffer mechanism, the first support cylinder and the second support cylinder, not only the road surface is protected, but also the damage risk of the snow plowing mechanism is reduced, the service life of the equipment is prolonged, and it will automatically buffer when encountering a hard object, reducing the impact force on the driver and improving driving safety;

[0015] 3. The mechanism of the present invention can be installed on the surface of the snowplow vehicle body through the installation components. Through the dampers on the installation components and the connecting plate that slides on the rear mounting frame after installation, the entire connecting component can slide up and down. When the snowplowing component encounters an uneven road surface, the snowplowing component can slide up and down and has a certain amount of up-and-down movement space, further protecting the snowplowing component.

[0016] 4. The knife plate mounting seat of the present invention is connected to the bucket welding piece through a buffer module, so that when the straight knife plate on the knife plate mounting seat encounters an uneven road surface, it can buffer up and down.

[0017] 5. By setting the support module, the present invention can support the entire snowplowing mechanism; after the snowplowing mechanism is removed from the snowplow vehicle body, it can be supported by the support module to improve its stability.

[0018] 6. An ice melting mechanism can also be set on the straight knife plate of the present invention. By continuously increasing the temperature inside the side protection frame, the temperature of the side inclined baffle will be increased. The side inclined baffle is made of a metal with high heat transfer efficiency. When the bucket main body shovels snow, the snow will accumulate on one side of the knife plate mounting seat due to gravity and be piled up under the pressure of the upper part of the snow gravity. At this time, through the continuously heated side inclined baffle, the ice and snow on one side of the knife plate mounting seat will be continuously melted, and the melted liquid will flow along the liquid guide groove. Through the setting of the ice melting mechanism, the efficiency of the snowplowing process is improved, and at the same time, the situation that more snow is compacted by gravity and adheres to one side of the bucket is avoided, improving the practicability of snowplowing.

[0019] 7. The present invention continuously stirs the snow or ice piled and compacted on one side of the knife plate mounting seat through the rotating ice breaking teeth. While crushing the ice, it also avoids the snow from being compacted and piled up. At the same time, the top transmission rod is made of a metal with high heat transfer efficiency, and the top transmission rod will heat up with the start of the heater, improving the efficiency of snow melting and snow removal.

[0051] The following combines the specification drawings and embodiments to elaborate on the content of the present invention in detail:

[0052] Embodiment 1:

[0053] As Figure 1 and 23 shown is a schematic diagram of a snow plowing mechanism provided by the present invention that can be applicable to different road surfaces.

[0054] The snow plowing mechanism applicable to different road surfaces includes a mounting component 1 for connecting with the snow plowing vehicle body, a connecting component 2 provided on the mounting component 1, a rotating shaft 4 provided on the connecting component 2, two sets of snow plowing components 3 rotatably connected to the rotating shaft 4 and symmetrically arranged left and right, and first support cylinders 9 and second support cylinders 901 respectively driving the corresponding snow plowing components 3 to swing and hinged between the corresponding snow plowing components 3 and the connecting component 2.

[0055] A control valve body 8 for controlling the operation of the first support cylinder 9 and the second support cylinder 901 and buffering and protecting the first support cylinder 9 and the second support cylinder 901 is further provided on the connecting component 2; an electromagnetic valve SV1805, an electromagnetic valve SV2806, a relief valve RV1801, a relief valve RV2802, a relief valve RV3803, and a check valve CV1804 are provided on the control valve body 8; an oil port A and an oil port B connected to an external oil supply system (this oil supply system can be a hydraulic oil supply system on the snow plowing vehicle body) are provided on the control valve body 8.

[0056] The operation of the first support cylinder 9 and the second support cylinder 901 is controlled by an oil circuit formed by connecting the oil port A, the electromagnetic valve SV1805, the oil port A1 of the cylinder barrel of the first support cylinder 9, the oil port A2 of the piston cylinder body of the first support cylinder 9, the oil port B2 of the piston cylinder body of the second support cylinder 901, the oil port B1 of the cylinder barrel of the second support cylinder 901, the electromagnetic valve SV2806, and the oil port B through pipelines.

[0057] The first support cylinder 9 is buffered and protected by an oil circuit formed by connecting the oil port A1 of the cylinder barrel of the first support cylinder 9, the relief valve RV1801, the check valve CV1804, the relief valve RV3803, and the oil port A2 of the piston cylinder body of the first support cylinder 9 through pipelines.

[0058] The oil circuit formed by connecting the oil port B1 of the cylinder barrel of the second support oil cylinder 901, the overflow valve RV2802, the one-way valve CV1804, the overflow valve RV3803, and the oil port B2 of the piston cylinder body of the second support oil cylinder 901 through pipelines buffers and protects the second support oil cylinder 901.

[0059] A buffer mechanism is further provided on the connection assembly 2. The buffer mechanism includes a diaphragm accumulator 204. The diaphragm accumulator 204 is divided into upper and lower chambers. The upper chamber is filled with inert gas, and an oil port T is communicated with the upper part of the lower chamber. The oil port T is connected to the overflow valve RV1801, the overflow valve RV2802, and the one-way valve CV1804 through pipelines respectively.

[0060] Through the installation assembly 1, the present invention can install this mechanism on the snowplow vehicle body. Through the connection assembly 2, the first support oil cylinder 9 and the second support oil cylinder 901, the snowplowing angle and the opening size of the snowplowing assembly 3 can be adjusted, and the snowplowing angle and force can be automatically adjusted according to the characteristics of different road surfaces, which is applicable to various road surface conditions such as urban roads, rural roads, and highways, and can meet the requirements of different scenarios at the same time. In addition, when the snowplowing assembly 3 contacts a hard object, the control valve body 8 and the support oil cylinder will rebound the snowplowing assembly 3 to avoid damaging the road surface. At the same time, under the combined action of the snowplowing assembly 3, the control valve body 8, the buffer mechanism, the first support oil cylinder 9 and the second support oil cylinder 901, not only the road surface is protected, but also the damage risk of this snowplowing mechanism is reduced, the service life of the equipment is extended, it will automatically rebound when encountering a hard object, the impact force on the driver is reduced, and the driving safety is improved.

[0061] Such as Figure 17As shown, when the snow plowing assembly 3 connected to the first support cylinder 9 is impacted, the first support cylinder 9 will retract at this time. The oil inside the first support cylinder 9 moves according to the gray arrow. The oil in the cylinder barrel of the first support 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 check valve CV1804 on the lower side respectively. There are two chambers in the diaphragm accumulator 204, with a diaphragm in the middle. Nitrogen is filled in the upper side, and the air pressure is 50 bar. When the oil enters the lower part of the diaphragm accumulator 204 from the T oil port, it will squeeze the diaphragm upward to compress the filled inert gas such as nitrogen, so as to buffer the flow rate of the oil, so as to control the retraction rate of the first support cylinder 9, thus playing the first buffering role for the first support cylinder 9 and the snow plowing assembly 3. At the same time, the oil will also enter the check valve CV1804. After passing through the check valve CV1804, the oil cannot flow back, and is divided into two streams again. One stream flows into the overflow valve RV3803, and the other stream of oil returns to the piston barrel of the first support cylinder 9 through the A2 oil port to keep the oil pressure in the first support cylinder 9 stable; the overflow valve RV3803 is connected to the check valve CV1804. The oil entering the check valve CV1804 will enter the overflow valve RV3803, but cannot flow back from the check valve CV1804 to the overflow valve RV1801. In this way, when the first support cylinder 9 retracts, the oil is first buffered by the diaphragm accumulator 204, and then is secondarily buffered by being secondarily divided through the check valve CV1804. At the same time, the oil returns to the piston barrel of the first support cylinder 9, which can also effectively protect the first support cylinder 9 and is not easy to cause damage to the first support cylinder 9. Similarly, when the second support cylinder 901 retracts when another snow plowing assembly 3 is impacted, the oil flow mode is the same as that of the first support cylinder 9, and will not be elaborated here.

[0062] Under the action of the external oil supply system, the control valve body 8 controls the operation modes of the first support cylinder 9 and the second support cylinder 901 as follows. Among them, the solenoid valves SV1805 and SV2806 control the operation of the two cylinders through the oil ports A and B respectively;

[0063] When controlling the first support cylinder 9 to be stationary and the second support cylinder 901 to retract, the oil port A feeds oil, and the oil port B returns oil. The solenoid valve SV1805 is not energized, and the solenoid valve SV2806 is not energized, as Figure 18 shown;

[0064] When controlling the first support cylinder 9 to be stationary and the second support cylinder 901 to extend, the oil port A returns oil, and the oil port B feeds oil. The solenoid valve SV1805 is not energized, and the solenoid valve SV2806 is not energized, as Figure 19 shown;

[0065] When controlling the first support oil cylinder 9 to extend and the second support oil cylinder 901 to retract, the oil port A intakes oil, the oil port B returns oil, the solenoid valve SV1805 is energized, and the solenoid valve SV2806 is de-energized, as Figure 20 shown;

[0066] When controlling the first support oil cylinder 9 to retract and the second support oil cylinder 901 to extend, the oil port A returns oil, the oil port B intakes oil, the solenoid valve SV1805 is energized, and the solenoid valve SV2806 is de-energized, as Figure 21 shown;

[0067] When controlling the first support oil cylinder 9 to retract and the second support oil cylinder 901 to remain stationary, the oil port A intakes oil, the oil port B returns oil, the solenoid valve SV1805 is de-energized, and the solenoid valve SV2806 is energized, as Figure 22 shown;

[0068] When controlling the first support oil cylinder 9 to extend and the second support oil cylinder 901 to remain stationary, the oil port A returns oil, the oil port B intakes oil, the solenoid valve SV1805 is de-energized, and the solenoid valve SV2806 is energized, as Figure 23 shown.

[0069] An installation hoop 203 is fixedly connected to the connection assembly 2, and the diaphragm accumulator 204 is movably connected within the installation hoop 203.

[0070] The solenoid valves SV1805 and SV2806 are fixedly connected to the rear end of the control valve body 8, and the relief valves RV1801, RV2802, RV3803, and the check valve CV1804 are fixedly connected to the front end of the control valve body 8.

[0071] The installation assembly 1 includes an installation rear frame 101;

[0072] A perforated plate 102 is provided on the surface of the installation rear frame 101. Two support hooks 103 for connecting with the snowplow vehicle body are fixedly connected to the installation rear frame 101. A longitudinally extending connection chute 108 is provided on the surface of the installation rear frame 101. A rear cover connection frame 109 is fixedly connected to the top of the installation rear frame 101. A top sliding sleeve rod 110 is provided on the rear cover connection frame 109. The upper end of the top sliding sleeve rod 110 is connected to the rear cover connection frame 109 through a connection bolt 111. A damper 104 is connected to the bottom of the top sliding sleeve rod 110. A front cover connection frame 112 is provided at the bottom of the damper 104;

[0073] The connection assembly 2 includes a connecting plate 206 slidably disposed on the installation rear frame 101. The front cover connection frame 112 is connected to the connecting plate 206. A slider 2061 is provided on the connecting plate 206. The slider 2061 is slidably disposed within the connection chute 108.

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

[0075] In order to make the entire installation assembly 1 form an integral body, two first plastic wear-resistant plates 105 are fixedly connected to the surface of the rear installation frame 101. A second plastic wear-resistant plate 106 is fixedly connected to the surface of the first plastic wear-resistant plate 105. A slider backing plate 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 installation frame 101 is installed on the snowplow vehicle body by using the orifice plate 102 and / or the support hook 103. When an external force acts on the snowplow assembly 3, the damper 104 expands and contracts, and the slider 2061 of the connecting plate 206 will slide longitudinally along the connecting chute 108. Under the action of the damper 104, the connecting plate 206 can move up and down, and at the same time, it can play a shock-absorbing effect on the connecting frame weldment 201. Moreover, through the damper 104, a certain movement space in the up and down direction can be realized between the connecting assembly 2 and the snowplow assembly 3, which can adapt to road surfaces with different heights. The rear installation frame 101 can be protected by the first plastic wear-resistant plate 105, the second plastic wear-resistant plate 106 and the slider backing plate 107, thereby increasing the service life.

[0077] A connecting frame weldment 201 is provided on the front wall surface of the connecting plate 206. The rotating shaft 4 is rotatably connected to the front end of the connecting frame weldment 201. The control valve body 8 is fixedly connected to the upper surface of the connecting frame weldment 201; An installation connecting plate 202 is fixedly connected to the connecting frame weldment 201. One ends of the first support oil cylinder 9 and the second support oil cylinder 901 are hinged to the installation connecting plate 202. Rubber buffer rods 205 for elastically buffering the snowplow assembly 3 are fixedly connected to the surfaces on both sides of the connecting frame weldment 201.

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

[0079] The installation hoop 203 is arranged on the installation connecting plate 202.

[0080] In a specific embodiment of the present invention, the rotating shaft 4 is fixed to the surface of the connecting frame weldment 201, and the control valve body 8 is respectively connected to the first supporting cylinder 9, the second supporting cylinder 901 and the diaphragm accumulator 204. When the snow shoveling component 3 encounters a hard object, it will compress the first supporting cylinder 9 or the second supporting cylinder 901. 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.

[0081] The surface of the rotating shaft 4 is fixedly connected to a shaft end cover 5 for limiting the two snow shoveling assemblies 3. The top of the rotating shaft 4 is fixedly connected to a support frame 6. The surface of the support frame 6 is rotatably connected to an upper rubber baffle 7.

[0093] Embodiment 2:

[0094] As Figures 24 - 29 shown: It is a schematic diagram of another embodiment provided by the present invention. This embodiment is similar to Embodiment 1 in terms of the main structure. The difference is that the snow shoveling mechanism further includes an ice melting mechanism 10 provided on the snow shoveling assembly 3. The ice melting mechanism 10 includes a side inclined baffle 1001, a liquid guide groove 1002 and a protection box 1003.

[0096] Specifically, the inner controller base 1006 drives the heater 1007 to work. Through the inner controller base 1006, the safe transmission of voltage can be controlled. After the heater 1007 is started, heat will be generated inside the side protection frame 1010, and the temperature inside the side protection frame 1010 will continue to rise. The L-bracket 1009 limits the side fixed plate 1008 to reduce the displacement of the side fixed plate 1008 during the process of driving and shoveling snow. By continuously increasing the temperature inside the side protection frame 1010, the temperature of the side inclined baffle 1001 will be increased. The side inclined baffle 1001 is made of a metal with high heat transfer efficiency. When the bucket main body 303 shovels snow, the snow will accumulate on one side of the straight blade 3021 due to gravity and be piled up under the pressure of the upper part of the snow. At this time, the continuously heated side inclined baffle 1001 will continuously melt the ice and snow on one side of the straight blade 3021.

[0099] Specifically, the rotating horizontal transmission rod 1106 will synchronously drive the two second side bevel gear plates 1108 to rotate, the rotating second side bevel gear plates 1108 will drive the second top bevel gear plate 1109 to rotate together with the first side bevel gear plate 1105, the rotating second top bevel gear plate 1109 will synchronously drive the top transmission rod 1110 to rotate, the rotating top transmission rod 1110 will rotate along the inner side of the limiting top plate 1112, the rotating top transmission rod 1110 will drive the ice-breaking blade teeth 1111 to rotate, and the rotating ice-breaking blade teeth 1111 will continuously stir the compacted snow or ice accumulated on one side of the straight blade plate 3021.

[0100] A method for using a snow shoveling mechanism applicable to different road surfaces comprises the following steps:

[0101] Use the orifice plate 102 and / or the support hook 103 to install the rear frame 101 on the surface of the snowplow body. At this time, the snowplow component 3 can start working, and at the same time, the opening of the bucket body 303 can be adjusted by starting the first support cylinder 9 and the second support cylinder 901 to adapt to different road surfaces; when the snowplow component 3 encounters a hard object, it will compress the first support cylinder 9 or the second support cylinder 901. At this time, the hydraulic oil inside the first support cylinder 9 or the second support cylinder 901 will be buffered and controlled through the control valve body 8 and the diaphragm accumulator 204 of the cache mechanism, thereby playing a buffering and protective role for the first support cylinder 9 or the second support cylinder 901. At the same time, under the action of the damper 104, the entire connecting component 2 and the snowplow component 3 can be shock-absorbing and buffered, thereby providing further effective protection for the snowplow component 3.
