At the same time, it should be understood that for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.
[0031] It should be further explained that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0032] Please refer to Figure 1-3 The embodiment of the utility model provides a multi-purpose road cleaning manual rake, which is mainly used for screening out debris and gravel in backfill soil, and includes a hand-held rod 1, a nail rake 3, a screen 2, an insertion rod 4 and a pull rope 5.
[0033] The hand-held rod 1 is a cylindrical straight rod for an operator to hold when using the multi-purpose road cleaning manual rake.
[0034] The spike rake 3 includes a fixed rod 301 and a plurality of rake teeth 302 fixed to the fixed rod 301. The lower end of the hand-held rod 1 is connected to the fixed rod 301, and the lower end of the hand-held rod 1 is vertically connected to the midpoint of the fixed rod 301. The rake teeth 302 are arranged at intervals along the length direction of the fixed rod 301, and are generally arranged at even intervals along the length direction of the fixed rod 301, so that large-diameter sand and debris in the backfill soil can be evenly raked out.
[0035] like Figure 4 As shown, the screen 2 includes a movable sleeve 201 and a mesh plate 202, wherein the movable sleeve 201 is rotatably sleeved on the fixed rod 301, and the movable sleeve 201 is specifically divided into a plurality of sections arranged at intervals, and each section of the movable sleeve 201 is sleeved on the portion of the fixed rod 301 between two adjacent rake teeth 302. The mesh plate 202 is covered with sieve holes, and the mesh plate 202 is arranged on the back of each rake tooth 302 and fixedly connected to the movable sleeve 201, so that the screen 2 can rotate around the fixed rod 301.
[0036] In some embodiments, the rake teeth 302 are arc-shaped teeth, and the mesh plate 202 is an arc-shaped plate. The rake teeth 302 can fit exactly on the front side of the mesh plate 202, so that the rake teeth 302 act as a skeleton to prevent the mesh plate 202 from deforming during use, thereby allowing stable use.
[0037] like Figure 6 As shown, the insertion rod 4 is arranged on the front of the mesh plate 202 and passes through the mesh plate 202, and the insertion rod 4 can lock or release the rake teeth 302 and the mesh plate 202. Specifically, a plurality of raised fixing rings 203 are arranged on the front of the mesh plate 202, and each of the fixing rings 203 is located on the same straight line, generally located on a straight line parallel to the fixing rod 301. The insertion rod 4 passes through each of the fixing rings 203 and presses each of the rake teeth 302, so that the mesh plate 202 can be fixed to the back of each of the rake teeth 302.
[0038] In some embodiments, in order to avoid affecting the screening effect of the mesh plate 202 , the fixing ring 203 is arranged close to the side of the rake teeth 302 , thereby reducing the screening area occupied by the mesh plate 202 .
[0039] In some embodiments, both ends of the insertion rod 4 are provided with a limit head 401, the limit head 401 is triangular, and the fixing ring 203 is a semicircular ring. After the insertion rod 4 is inserted into each of the fixing rings 203, the limit head 401 is located on the outside of the fixing rings 203 on both sides, and when the insertion rod 4 is rotated to make the limit head 401 rotate to be vertical or inclined with the mesh plate 202, the limit head 401 is blocked by the fixing ring 203 to prevent the insertion rod 4 from falling off when the screen 2 is working; and when the insertion rod 4 is rotated to make the limit head 401 rotate to fit with the mesh plate 202, the limit head 401 is released by the fixing ring 203, and the insertion rod 4 can be pulled out by the fixing ring 203.
[0040] Combination Figure 5 As shown, the pull rope 5 is generally a steel wire rope, one end of which is connected to the back of the mesh plate 202, and the other end is detachably connected to the hand-held rod 1, so as to tighten the screen 2. Specifically, a reverse pull ring 204 is provided on the back of the mesh plate 202, and one end of the pull rope 5 is connected to the reverse pull ring 204. A winding ring 101 is provided on the hand-held rod 1, and the other end of the pull rope 5 is detachably connected to the winding ring 101. The screen 2 can be tightened by the pull rope 5, so that the screen 2 is in a stable state.
[0041] In some embodiments, in order to ensure that the pull rope 5 is in a stable tensioned state, the movable sleeve 201 is provided with a constraint groove 205 near the lower end of the hand-held rod 1. The pull rope 5 bypasses the constraint groove 205 and fits against the surface of the hand-held rod 1. Under the restrictive effect of the constraint groove 205, the pull rope 5 cannot slide and can always remain in a tensioned state.
[0042] The process of screening backfill soil using this multi-purpose road cleaning manual rake is as follows:
[0043] First, clean up the large-diameter sand, gravel, branches, weeds and other debris in the backfill soil: Figure 3 As shown, the insertion rod 4 is pulled out to separate the screen 2 from the nail rake 3, the screen 2 is rotated to the rear of the nail rake 3, the pull rope 5 is pulled to tighten the screen 2 and then the pull rope 5 is tied to the winding ring 101, and then the hand-held rod 1 is held to rake the backfill soil through the nail rake 3 to rake away large-diameter sand, gravel, branches, weeds and other debris in the backfill soil;
[0044] Then the small particles of sand and gravel in the backfill soil are screened: Figure 1 and 2As shown, the pull rope 5 is untied from the winding ring 101, the screen 2 is rotated to make it fit with the back of the spike rake 3, the insertion rod 4 is inserted into each of the fixing rings 203, the pull rope 5 is pulled to tighten the screen 2 and then the pull rope 5 is tied to the winding ring 101, and then the hand-held rod 1 is held to screen the backfill soil through the screen 2, and small particles of sand and gravel in the backfill soil are screened out to obtain qualified soil materials that meet the backfill requirements.
