TECHNICAL FIELD
[0001] The present application relates to the technical field of road construction equipment, in particular to a road construction paver. BACKGROUND
[0002] At present, small asphalt pavers are mechanical equipment specially designed for laying asphalt pavement in small-scale projects, such as sidewalks, parking lots, internal roads of communities, and rural roads. Compared with large asphalt pavers, such equipment is smaller in size and more flexible, and is suitable for situations where the space is relatively small or the laying area is small. Among them, hand-push small asphalt pavers are particularly popular because they are easy to operate, do not require special driving skills, and are relatively low in cost. For work that needs to quickly repair or pave a small area of road, such equipment is an ideal choice.
[0003] The structure of the above-mentioned hand-push asphalt paver mainly includes a machine body and a hopper provided on the machine body. Before construction, asphalt is poured into the hopper from the opening at the top of the hopper, and the asphalt will continuously accumulate on the bottom plate, which is inclined downward. A screw feeder is provided at the bottom of the hopper and is composed of one or more pairs of spiral blades. The asphalt on the bottom plate will continuously flow to the screw feeder under the action of gravity, and the screw feeder is responsible for uniformly distributing the asphalt within the paving width range. For the above-mentioned asphalt paver, as the asphalt cools, the residual asphalt on the bottom plate will continuously increase, and if it is not cleaned in time, the residual asphalt will affect the normal discharge of the asphalt. However, the one-piece hopper will make the cleaning work more difficult. CONTENT OF THE UTILITY MODEL
[0004] The present application provides a road construction paver, which has the effect of facilitating the cleaning of residual asphalt, thereby ensuring the normal discharge of asphalt.
[0005] The road construction paver provided by the present application adopts the following technical scheme:

A bottom plate is detachably installed on the hopper, a plurality of plug-in plates are provided on the bottom plate, a plug-in slot corresponding to each plug-in plate is provided on the hopper, and the plug-in plates and the respective plug-in slots are mutually plug-in matched. A locking frame is provided on the outer side wall of the hopper, a locking hole is provided through the plug-in plate, the locking frame is sequentially provided in the respective locking holes, a positioning column is provided on the outer side wall of the hopper, the locking frame is provided outside the positioning column, a fastener is threadedly connected to the positioning column, and the fastener tightly fixes the locking frame on the hopper.
[0007] Preferably, a limiting groove is arranged on the outer side wall of the bin, the locking frame is limited in the limiting groove, and the positioning column is fixedly arranged on the inner side wall of the limiting groove.
[0008] Preferably, a rocker is rotatably arranged on the outer side wall of the bin, the rocker is located below the bottom plate, and the bottom plate is located on the rotation path of the rocker; and a handle is arranged at the end of the rocker away from the bottom plate.
[0009] Preferably, two groups of rockers are arranged symmetrically on the two sides of the bin.

[0011] Preferably, the cover plate is rotatably arranged on the bin on one side, and a handle is arranged on the top of the cover plate.
[0012] Preferably, a locking rod located on one side of the cover plate is threadedly connected to the top of the bin, and a fixing hole is arranged through the cover plate for inserting the end of the locking rod into the cover plate.
[0013] In summary, the present application has at least one of the following beneficial technical effects:
[0014] When the residual asphalt on the bottom plate needs to be cleaned, the fastener is first unscrewed from the positioning column, and then the locking frame is removed from the locking hole, so that the locking of the bottom plate is released; in order to facilitate the construction personnel to take out the bottom plate from the bin, the bottom plate is lifted out of the bin by means of the two side rockers, so that the bottom plate and the bin can be smoothly separated, the bottom plate is taken out of the bin, and the residual asphalt on the bottom plate is cleaned in time, so that the normal discharge of asphalt can be ensured, the disassembly and assembly process of the bottom plate is convenient and fast, and the disassembly and assembly efficiency is improved.

DETAILED DESCRIPTION
[0021] The application will be further described in detail below with reference to the accompanying drawings.
[0022] The application discloses a road construction paver.
[0023] Reference Figure 1 , Figure 2 and Figure 3 , the road construction paver comprises a machine body 1 and a hopper 2 arranged above the machine body 1. A bottom plate 3 for receiving asphalt is detachably installed on the inner side wall of the bottom of the hopper 2, and the bottom plate 3 is arranged in a downward inclined manner. A plurality of plug-in plates 30 are fixedly installed on the bottom side wall of the bottom plate 3, and the hopper 2 is provided with plug-in slots 20 corresponding to the plug-in plates 30 one by one, the plug-in plates 30 are respectively inserted and fixed in the respective opposite plug-in slots 20, and the plug-in plates 30 and the plug-in slots 20 are mutually plug-in matched.
[0024] As shown in Figure 3 , Figure 4 , a locking frame 4 is installed on the outer side wall of the bottom of the hopper 2, and the locking frame 4 comprises a cross frame 40 and two plug-in rods 41 symmetrically fixed on both sides of the cross frame 40, and the two plug-in rods 41 are parallel to each other. The plug-in plates 30 are provided with locking holes 31, and the plug-in rods 41 are sequentially inserted into the respective opposite locking holes 31. The plug-in direction of the plug-in rod 41 is perpendicular to the direction of the plug-in plate 30 inserted into the plug-in slot 20.
[0025] As shown in Figure 3 , Figure 4 , a limiting slot 21 is arranged on the outer side wall of the hopper 2 and faces the cross frame 40, and the cross frame 40 is plug-in limited in the limiting slot 21. A positioning column 5 is fixedly installed on the inner side wall of the limiting slot 21, and the length of the positioning column 5 extends along the length direction of the plug-in rod 41. The cross frame 40 is inserted outside the positioning column 5, and a fastener 50 is threadedly connected to the positioning column 5, and the fastener 50 is used for rotating and fixing the locking frame 4 on the hopper 2. The bottom plate 3 is fixedly installed on the hopper 2 through the locking frame 4.
[0026] As shown in Figure 3 , Figure 4As shown, the bottom outer side wall of the bin 2 is also rotatably provided with two groups of jack rods 6, which are symmetrically arranged on the two sides of the bin 2. Both groups of jack rods 6 are located below the bottom plate 3, and the bottom plate 3 is located on the rotating path of the jack rods 6; one end of the jack rod 6 away from the bottom plate 3 is fixedly provided with a handle 60, which facilitates the rotation of the jack rod 6 by the construction personnel. With the aid of the two side jack rods 6, the bottom plate 3 can be easily lifted out of the bin 2, thereby realizing the smooth separation of the bottom plate 3 and the bin 2.
[0027] As shown in Figure 2 , Figure 3 , the top of the bin 2 is provided with a cover plate 7 for sealing and covering the top opening of the bin 2.
