Description

Technical Field

[0001] This utility model relates to the field of snow removal machinery, specifically to a side shovel installed in the middle of a truck. Background Technology

[0002] A snowplow is a tool mainly used for clearing snow. The snowplow mounting bracket is connected to the truck frame and can be fixed with fasteners such as bolts and nuts. It is necessary to ensure that the connection is firm and reliable.

[0003] Currently, the snowplows used have a hydraulic cylinder and spring structure. The hydraulic cylinder controls the raising and lowering of the snowplow. Before starting snow removal operations, the hydraulic cylinder raises the snowplow to a suitable height. After the operation, raising the snowplow facilitates the vehicle's return journey and prevents the snowplow from scraping the road surface. When encountering large obstacles that are difficult to push over, the hydraulic cylinder quickly raises the snowplow to prevent damage from hard impacts, protecting the equipment and reducing maintenance costs. The spring mainly provides the snowplow with a certain degree of vertical movement. Snow surfaces are rarely completely flat; when there are undulations, the spring allows the snowplow to flexibly conform to the terrain, maintaining a close contact with the snow surface and avoiding gaps in snow removal, thus improving the evenness of snow removal. At the same time, during snow removal, impacts are inevitable, such as hitting rocks or protrusions hidden under the snow. The spring can buffer these sudden impacts and reduce equipment vibration.

[0004] Because the lifting mechanism of the hydraulic cylinder and the floating mechanism of the snowplow are two independent structures, they cannot be well coordinated. When the snow is too thick or too hard, the working resistance of the snowplow will increase, which may cause the hydraulic cylinder lifting and the spring floating mechanism to become asynchronous. Furthermore, uneven road surfaces will cause uneven impact forces on the snowplow, affecting the coordinated work of the hydraulic cylinder and the spring. Therefore, the asynchronous lifting of the snowplow's hydraulic cylinder and the spring floating mechanism will lead to poor snow removal efficiency. Utility Model Content

[0005] In order to solve the problem that the lifting of the hydraulic cylinder and the floating of the spring in the existing shovel cannot be well connected, and the working resistance of the shovel will increase when the snow is too thick or too hard, this utility model provides a side shovel installed in the middle of the truck.

[0006] The technical solution of this utility model is:

[0007] A side-mounted shovel installed in the middle of a truck includes a shovel body, a shovel frame rotatably mounted on the back of the shovel body, and a hydraulic cylinder. The shovel body is hinged together by a support pivot on the shovel frame. The shovel body also includes a spring, the tail of which is elastically connected to a sliding pivot on the shovel frame, and the head of which is connected to the shovel body by the hydraulic cylinder.

[0008] Furthermore, it also includes a connecting cylinder and a slider disposed within the connecting cylinder, wherein the connecting cylinder, slider, oil cylinder, and spring constitute a spring oil cylinder.

[0009] The connecting cylinder has an insertion hole for installing the hydraulic cylinder. The tail of the hydraulic cylinder passes through the insertion hole of the connecting cylinder and is connected to a shallow slot at one end of the slider. The spring and the slider are installed in the connecting cylinder, and the deep slot on the slider allows the spring to rest against the plane of the deep slot. The other end of the spring rests against the inner wall of the slider. The tail of the hydraulic cylinder pushes the slider to slide in the connecting cylinder.

[0010] Furthermore, the slider is a cylindrical structure, with its outer diameter smaller than the inner diameter of the connecting cylinder, allowing the slider to slide within the connecting cylinder.

[0011] Furthermore, shallow slots and deep slots are respectively provided at both ends of the slider. The deep slot is used to limit the spring, and the shallow slot is used to limit the tail of the oil cylinder.

[0012] Furthermore, a connecting frame is connected to the back of the shovel body, and the shovel body and the connecting frame are rotatably connected, with the connecting frame disposed between the two shovel frames.

[0013] Furthermore, the shovel frame consists of two rotating plates, and a spring cylinder is disposed between the two rotating plates. The shovel frame is used to connect the tail end of the spring cylinder.

[0014] Furthermore, a corner cylinder is installed between the shovel body and the connecting frame. The tail of the corner cylinder is connected to the arc-shaped protrusion on the connecting frame. The corner cylinder pushes the telescopic end to change the angle of the shovel body in the lateral direction.

[0015] Furthermore, a slewing bearing is connected to the connecting frame, and the slewing bearing is rotatably connected to the shovel body. The slewing cylinder drives the shovel body to swing to the left or right through the slewing bearing.

[0016] Furthermore, a vertical plate is connected to the top of the connecting frame, and the vertical plate is fixedly connected to the mounting plate by a set of bolt assemblies. The mounting plate and the connecting frame are vertically connected.

[0017] Furthermore, the mounting plate has mounting holes, and the mounting plate is inserted into the beam at the lower front, lower middle, or lower rear of the vehicle body to connect the shovel body.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This utility model is mainly used for scraping various types of ice and snow on the road surface, and can also swing to the left or right to remove snow. The spring cylinder, which consists of a spring, a cylinder, a rear connecting cylinder, and a slider, is responsible for lifting the shovel body off the road surface. At the same time, the spring cylinder has a floating spring inside as an elastic mechanism to ensure that the shovel body can float and follow the shape of the road surface during operation, and can also ensure that the shovel body can elastically flip backward to avoid obstacles when it encounters obstacles on the road surface.

[0020] This utility model can be installed on any part of a truck or construction machinery, such as the lower front, lower middle, or lower rear, and is driven forward by the truck or construction machinery for operation. During operation, the lower part of the shovel body contacts the ice and snow on the road surface, scraping away various types of ice and snow. At the same time, the shovel body can be tilted left or right by a swivel cylinder, allowing the scraped ice and snow to be discharged to the left or right. The shovel body can also be elastically tilted backward by a spring cylinder, ensuring that the shovel body can follow the shape of the road surface and can also tilt backward to automatically avoid various obstacles on the road surface without causing damage to the equipment.

[0021] This invention connects the spring and the hydraulic cylinder together, replacing the traditional independent structure of the hydraulic cylinder and spring in the shovel. After the spring and the hydraulic cylinder are connected together, the hydraulic cylinder and the spring can force pressure on the shovel body, improving the effect of scraping ice and snow.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Specific implementation method one:

[0034] Combination Figure 1 — Figure 5 This embodiment describes a side-mounted shovel installed in the middle of a truck. It includes a shovel body 1 and a shovel frame 2 rotatably mounted on the back of the shovel body 1, allowing the shovel body 1 to rotate via a support shaft 9 on the shovel frame 2. It also includes a spring 3, the tail of which is elastically connected to a sliding shaft 10 on the shovel frame 2. The telescopic rod at the head of the spring 3 is connected to the shovel body 1, and the spring 3 adjusts the angle of the shovel body 1 via the telescopic rod.

[0035] The side-discharge shovel also includes a connecting cylinder 31, a slider 32, a hydraulic cylinder 33, and a slider 32 disposed inside the connecting cylinder 31;

[0036] The connecting cylinder 31 has an insertion hole for installing the hydraulic cylinder 33. The tail of the hydraulic cylinder 33 passes through the insertion hole of the connecting cylinder 31 and is connected to a shallow slot at one end of the slider 32. The spring 3 and the slider 32 are installed inside the connecting cylinder 31, and the deep slot on the slider 32 causes the spring 3 to abut against the plane of the deep slot. The other end of the spring 3 abuts against the inner wall of the slider 32. The tail of the hydraulic cylinder 33 will push the slider 32 to slide in the connecting cylinder 31.

[0037] The spring 3 is combined with the oil cylinder 33, connecting the spring and the oil cylinder together, replacing the traditional independent structure of the shovel oil cylinder and spring. After the spring and oil cylinder are connected together, the oil cylinder and spring can force pressure on the shovel body, improving the effect of scraping ice and snow. Specific Implementation Method Two:

[0039] Combination Figure 1 — Figure 5 This embodiment describes a side-mounted shovel installed in the middle of a truck. The slider 32 is generally cylindrical, and the outer diameter of the slider 32 is smaller than the inner diameter of the connecting cylinder 31, so that the slider 32 slides in the connecting cylinder 31.

[0040] The connecting cylinder 31 has a cylindrical structure. When the slider 32 and the spring 3 are installed inside the connecting cylinder 31, the end of the connecting cylinder 31 is fixed with a sealing plate by means of welding. Thus, the spring 3 and the slider 32 are installed through the connecting cylinder 31, so that the spring 3 slides in the connecting cylinder 31. Specific implementation method three:

[0042] Combination Figure 4 and Figure 5 This embodiment describes a side shovel installed in the middle of a truck. The slider 32 has shallow slots and deep slots at both ends. The deep slots are used to limit the spring 3, and the shallow slots are used to limit the tail of the hydraulic cylinder 33.

[0043] The slider 32 has shallow slots and deep slots at both ends, and the shallow slots and deep slots are cylindrical slot structures. The shallow slots and deep slots on the slider 32 are mainly used for the installation of the spring 3 and the oil cylinder 33, so that the oil cylinder 33 can slide through the slider 32. Specific implementation method four:

[0045] Combination Figure 6 This embodiment describes a side shovel installed in the middle of a truck. The back of the shovel body 1 is connected to a connecting frame 4, and the shovel body 1 and the connecting frame 4 are rotatably connected. The connecting frame 4 is disposed between two shovel frames 2.

[0046] The connecting frame 4 has a concave structure. Mounting plates 7 are connected to the two sides above the connecting frame 4. The mounting plates 7 are rectangular steel plates. The distance between the two mounting plates 7 is greater than the width of the beam of the vehicle body. The two mounting plates 7 on the connecting frame 4 are fixed to the beam of the vehicle body, thereby fixing the shovel in place. Specific implementation method five:

[0048] Combination Figure 7 and Figure 8 This embodiment describes a side-mounted shovel installed in the middle of a truck, with a corner cylinder 5 installed between the shovel body 1 and the connecting frame 4. The tail of the corner cylinder 5 is connected to the arc-shaped protrusion on the connecting frame 4. The telescopic end of the corner cylinder 5 rotates with the shovel body 1, and the corner cylinder 5 pushes the telescopic end on the corner cylinder 5 to change the angle in the lateral direction of the shovel body 1.

[0049] The corner cylinder 5 specifically consists of two structures. When the shovel body 1 is rotated, one corner cylinder 5 performs a pushing action, while the other corner cylinder 5 performs a retracting action, thereby completing the lateral rotation of the shovel body 1 through the cooperation of the two corner cylinders 5. Specific implementation method six:

[0051] Combination Figure 7 and Figure 8 This embodiment describes a side shovel installed in the middle of a truck. A slewing bearing 6 is connected to the connecting frame 4. The slewing bearing 6 is rotatably connected to the shovel body 1. The slewing cylinder 5 drives the shovel body 1 to swing left or right through the slewing bearing 6.

[0052] The slewing bearing 6 can drive the shovel body 1 to swing to the left or right to clear snow. The spring cylinder is responsible for lifting the shovel body 1 off the road surface. At the same time, the spring cylinder is equipped with elastic mechanisms such as spring 3 inside to ensure that the shovel body 1 can float and follow the shape of the road surface during operation, and can also ensure that the shovel body 1 can elastically flip backward to avoid obstacles when it encounters obstacles on the road surface. Specific implementation method seven:

[0054] Combination Figure 7 and Figure 8 This embodiment describes a side-mounted shovel installed in the middle of a truck. The top of the connecting frame 4 is connected to a vertical plate, which is fixedly connected to a mounting plate 7 by a set of bolts. The mounting plate 7 is vertically connected to the connecting frame 4.

[0055] The mounting plate 7 on the top of the connecting frame 4 can be installed at any part of the truck or construction machinery, such as the lower front, lower middle, or lower rear, so that it can be driven forward by the truck or construction machinery. Detailed implementation method eight:

[0057] Combination Figure 7 and Figure 8 This embodiment describes a side-mounted shovel installed in the middle of a truck. The mounting plate 7 has mounting holes and is inserted into the lower front, lower middle, or lower rear beam of the vehicle body 8 to connect the shovel body 1.

[0058] During operation, the lower part of the shovel body 1 contacts the ice and snow on the road surface, scraping away various types of ice and snow. Simultaneously, the shovel body 1 can be tilted left or right by the corner cylinder 5, allowing the scraped ice and snow to be discharged to the left or right. The shovel body 1 can also be elastically tilted backward by a spring cylinder, ensuring it conforms to the road surface and automatically avoids various obstacles without causing damage, thus extending the equipment's lifespan. This prevents uneven impact on the shovel body when installed on uneven road surfaces, which could affect the coordinated operation of the cylinders and springs. Specific implementation method nine:

[0060] Combination Figure 1 — Figure 9This embodiment describes a side shovel installed in the middle of a truck. The shovel frame 2 consists of two rotating plates, and a spring cylinder is disposed between the two rotating plates. The shovel frame 2 is used to connect the tail of the spring cylinder.

[0061] The spring cylinder contains a spring 3 and a cylinder 33, which are connected together. In contrast to the traditional shovel 1 where the cylinder 33 and spring are independent structures, the connection between the spring 3 and the cylinder 33 allows for forced pressure to be applied to the shovel body 1, thereby improving the snow and ice removal effect.

[0062] During operation, the lower part of the shovel body 1 contacts the ice and snow on the road surface, scraping away various types of ice and snow. Simultaneously, the shovel body 1 can be tilted left or right by the corner cylinder 5, allowing the scraped ice and snow to be discharged to the left or right. The shovel body 1 can also be elastically tilted backward by a spring cylinder, ensuring it follows the shape of the road surface and automatically avoids various obstacles without causing damage. When the snow accumulation is too thick or too hard, the working resistance of the shovel body 1 increases; in this case, the spring cylinder synchronizes the lifting of the cylinder with the floating of the spring.
