Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction technology, and in particular to a self-propelled lime spreader. Background Technology
[0002] Lime is often spread on the roadbed during road construction. In lime-improved soil roadbed construction, the role of lime mainly includes ion exchange, cementation and hardening, water absorption and drainage, and stabilization of expansion and contraction. Through physical and chemical actions, it comprehensively improves the performance of the roadbed. When spreading lime, a spreader truck is required.
[0003] Currently, the ash spreading parts of the spreaders used in ash spreading are usually fixed structures and cannot be adjusted. Since the width of the road surface to be ash spread is usually different, when encountering a wider road surface, it is necessary to spread ash multiple times, which wastes a lot of time and also affects the construction progress. Utility Model Content
[0004] This utility model provides a self-propelled lime spreader, which can adjust the overall width of the main lime spreading trough and the extended lime spreading trough according to the road width. It can complete the lime spreading in one go even when encountering a wide road surface, reducing wasted time and ensuring construction progress.
[0005] In a first aspect, this utility model provides a self-propelled lime spreader, including a lime spreading vehicle with a storage compartment on its top. The top of the lime spreading vehicle also has two main lime spreading troughs, each with a lime spreading roller rotatably mounted inside. A dual-shaft motor is installed between the two main lime spreading troughs, with both ends of the motor's main shaft connected to one end of each of the lime spreading rollers inside the two main lime spreading troughs. An extended lime spreading trough is installed on one side of each main lime spreading trough, with a lime spreading roller also rotatably mounted inside each extended trough. Each extended trough's lime spreading roller has a connecting sleeve at the end near the main lime spreading trough.
[0006] As an optimization, each of the ash-spreading rollers is provided with a rectangular protrusion at one end, and each of the connecting sleeves is provided with an open rectangular groove on the inner side, and the rectangular protrusion at one end of the ash-spreading roller can adapt to the inner wall of the rectangular groove on the inner side of the connecting sleeve.
[0007] As an optimization, the lower portions of the main ash spreading trough and the extended ash spreading trough are both semi-cylindrical shells, and the outer wall of the ash spreading roller is in contact with the inner wall of the semi-cylindrical shells below the main ash spreading trough and the extended ash spreading trough.
[0008] As an optimization, after the L-shaped plate on one side of the extended ash spreading trough is inserted into the U-shaped plate on the side of the main ash spreading trough, the rectangular protruding rod at one end of the ash spreading roller will be embedded in the rectangular groove inside the connecting sleeve.
[0009] As an optimization, the outer side of the ash-spreading roller is provided with six elongated grooves arranged in a ring, the bottom of the main ash-spreading groove and the extended ash-spreading groove are both provided with an elongated opening, and the bottom plate of the ash-spreading vehicle is also provided with two rectangular openings.
[0010] As an optimization, the extended ash spreading trough is assembled on one side of the main ash spreading trough and is at the same height as the main ash spreading trough. Moreover, the outer side of the L-shaped plate on one side of the extended ash spreading trough is wrapped with a layer of rubber.
[0011] As an optimization, a U-shaped plate is fixed to one side of both the main ash spreading trough and the extended ash spreading trough, and an L-shaped plate is fixed to the other side of both extended ash spreading troughs.
[0012] This utility model has the following beneficial effects:
[0013] In this invention, the main ash spreading trough is fixed on the ash spreading vehicle, and the extended ash spreading trough can be easily installed on one side of the main ash spreading trough and disassembled. During ash spreading, the ash spreading rollers inside the main ash spreading trough and the extended ash spreading trough rotate to convey the lime downwards to complete the ash spreading. When using this spreader for ash spreading, the overall width of the main ash spreading trough and the extended ash spreading trough can be adjusted according to the road width. Even on wider roads, ash spreading can be completed in one go, reducing wasted time and ensuring construction progress. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Example 1: Please refer to Figures 1 to 6 :
[0027] This utility model proposes a self-propelled lime spreader, including a lime spreading vehicle 1; a storage compartment 2 is provided on the top of the lime spreading vehicle 1, which supports the lime spreading structure of the equipment. The storage compartment 2 can store the lime to be spread and an extended lime spreading trough 6; the top of the lime spreading vehicle 1 is also provided with two main lime spreading troughs 3, and a lime spreading roller 5 is rotatably installed inside each main lime spreading trough 3. A dual-shaft motor 4 is also installed between the two main lime spreading troughs 3, and the two ends of the main shaft of the dual-shaft motor 4 are respectively connected to one end of the lime spreading roller 5 inside the two main lime spreading troughs 3. The main lime spreading troughs 3 are used to hold lime, and the lime spreading roller 5 can convey the lime downwards to achieve lime spreading when it rotates. Motor 4 drives the ash-spreading roller 5 to rotate; an extended ash-spreading trough 6 is installed on one side of the main ash-spreading trough 3, and an ash-spreading roller 5 is also rotatably installed inside the extended ash-spreading trough 6. The end of the ash-spreading roller 5 inside the extended ash-spreading trough 6 near the main ash-spreading trough 3 is provided with a connecting sleeve 7. The extended ash-spreading trough 6 is also used to hold lime, and after the extended ash-spreading trough 6 is installed, the ash-spreading width of this equipment can be increased. When assembling the extended ash-spreading trough 6, the rectangular protrusion at one end of the ash-spreading roller 5 inside the main ash-spreading trough 3 will be embedded in the rectangular groove inside the connecting sleeve 7, so that the ash-spreading roller 5 inside the main ash-spreading trough 3 and the extended ash-spreading trough 6 can be connected together.
[0028] In this embodiment, as Figures 1-6As shown, each of the ash-spreading rollers 5 has a rectangular protruding rod at one end, and each of the connecting sleeves 7 has an open rectangular groove on its inner side. The rectangular protruding rod at one end of the ash-spreading roller 5 can adapt to the inner wall of the rectangular groove on the inner side of the connecting sleeve 7. When the extended ash-spreading trough 6 is assembled, the rectangular protruding rod at one end of the ash-spreading roller 5 on the inner side of the main ash-spreading trough 3 will be embedded in the rectangular groove on the inner side of the connecting sleeve 7. Therefore, the ash-spreading rollers 5 on the inner sides of the main ash-spreading trough 3 and the extended ash-spreading trough 6 can be connected together by a drive.
[0029] In this embodiment, as Figures 1-6 As shown, the lower parts of the main ash spreading trough 3 and the extended ash spreading trough 6 are both semi-cylindrical shells, and the outer wall of the ash spreading roller 5 is in contact with the inner wall of the semi-cylindrical shells below the main ash spreading trough 3 and the extended ash spreading trough 6. Therefore, during the rotation of the ash spreading roller 5, it will rely on the long strip groove on its outer side to transport the lime downward.
[0030] In this embodiment, as Figures 3-5 As shown, after the L-shaped plate on one side of the extended ash spreading trough 6 is inserted into the U-shaped plate on one side of the main ash spreading trough 3, the rectangular protruding rod at one end of the ash spreading roller 5 will be embedded in the rectangular groove inside the connecting sleeve 7. Therefore, while assembling the extended ash spreading trough 6, the ash spreading roller 5 can also be automatically connected together.
[0031] In this embodiment, as Figure 2 and Figures 4-6 As shown, the outer side of the ash-spreading roller 5 has six elongated grooves arranged in a ring. The bottom of the main ash-spreading trough 3 and the extended ash-spreading trough 6 are both provided with an elongated opening. The bottom plate of the ash-spreading vehicle 1 is also provided with two rectangular openings. During the rotation of the ash-spreading roller 5, it will rely on the elongated grooves on its outer side to transport the lime downwards. When the ash-spreading roller 5 drives the lime downwards to the bottom, the lime will fall out through the elongated openings at the bottom of the main ash-spreading trough 3 and the extended ash-spreading trough 6. Moreover, the bottom plate of the ash-spreading vehicle 1 will not obstruct the lime.
[0032] In this embodiment, as Figures 1-6 As shown, a U-shaped plate is fixed to one side of both the main ash spreading trough 3 and the extended ash spreading trough 6, and an L-shaped plate is fixed to the other side of the extended ash spreading trough 6. When installing the extended ash spreading trough 6, simply place the L-shaped plate on one side of the extended ash spreading trough 3 above the U-shaped plate on the other side of the main ash spreading trough 3, and rotate the opening on the outside of the connecting sleeve 7 to face downwards. Then, the extended ash spreading trough 6 can be pushed downwards as a whole. During this process, the L-shaped plate on one side of the extended ash spreading trough 6 will be embedded in the empty groove inside the U-shaped plate on one side of the main ash spreading trough 3, thus fixing the extended ash spreading trough 6 to one side of the main ash spreading trough 3.
[0033] Example 2, based on Example 1, such as Figures 1-6As shown, after the extended ash spreading trough 6 is assembled on one side of the main ash spreading trough 3, it will be at the same height as the main ash spreading trough 3. Moreover, the outer side of the L-shaped plate on one side of the extended ash spreading trough 6 is wrapped with a layer of rubber. Therefore, the integrality between the extended ash spreading trough 6 and the main ash spreading trough 3 is stronger after assembly. In addition, the rubber on the outer side of the L-shaped plate on one side of the extended ash spreading trough 6 can also increase the friction and prevent the extended ash spreading trough 6 from becoming loose during the operation of the ash spreading vehicle 1.
[0034] The working principle of this embodiment is as follows: The storage compartment 2 can store the lime to be spread and the extended lime spreading trough 6. When this equipment is needed to spread lime on the roadbed, the installation of the extended lime spreading trough 6 can be selected according to the width of the road. If the road is narrow, the extended lime spreading trough 6 does not need to be installed. If the road is wide, the extended lime spreading trough 6 can be installed. When installing the extended lime spreading trough 6, simply place the L-shaped plate on one side above the U-shaped plate on the side of the main lime spreading trough 3, and rotate the opening on the outside of the connecting sleeve 7 to face downwards. Then, the extended lime spreading trough 6 can be pushed downwards as a whole. During this process, the L-shaped plate on one side of the extended lime spreading trough 6 will be embedded in the empty groove on the inside of the U-shaped plate on the side of the main lime spreading trough 3. Therefore, the extended lime spreading trough 6 can be fixed on the side of the main lime spreading trough 3. At the same time, the rectangular protrusion at one end of the lime spreading roller 5 inside the main lime spreading trough 3 will be embedded in the rectangular recess on the inside of the connecting sleeve 7. The main ash spreading trough 3 and the extended ash spreading trough 6 can be connected together by a transmission of the ash spreading roller 5 inside. Furthermore, the other side of the extended ash spreading trough 6 can be further installed. After assembly, lime can be poured into the main ash spreading trough 3 and the extended ash spreading trough 6. Then, the dual-shaft motor 4 is powered on. When the dual-shaft motor 4 rotates, it drives the ash spreading roller 5 inside the main ash spreading trough 3 and the extended ash spreading trough 6 to rotate synchronously. During the rotation of the ash spreading roller 5, the lime is conveyed downwards by the long groove on its outer side. When the ash spreading roller 5 drives the lime downwards to the bottom, the lime will fall out through the long opening at the bottom of the main ash spreading trough 3 and the extended ash spreading trough 6. The bottom plate of the ash spreading vehicle 1 will not obstruct the lime. Then, the driver can drive the ash spreading vehicle 1 on the road surface to evenly spread the qualified soil material on the roadbed according to the designed loose-lay thickness.
