Description

Technical Field

[0001] The utility model relates to the technical field of trowel machines, in particular to a trowel machine for prefabricated parts. Background Art

[0002] Concrete precast panels come in a variety of specifications. After the concrete is poured and vibrated into the mold box, a grinder is needed to smooth it.

[0003] The current trowel machines use a method of smearing the top surface of the prefabricated part with a trowel plate straightly or a method of smearing with a rotating trowel piece. Both of the above methods have the problem that the size of the trowel plate or the trowel piece cannot be adaptively adjusted. When troweling prefabricated parts of different sizes, it is necessary to adjust the position of the trowel plate or the trowel piece to complete the horizontal trowel coverage, which affects the working efficiency of the trowel machine to a certain extent.

[0004] Therefore, the present invention provides a trowel machine for prefabricated parts, which has a trowel plate with a variable overall width through structural settings, so that the overall width of the trowel plate is adapted to the overall width of the prefabricated parts. Utility Model Content

[0005] The utility model aims at at least solving the problem in the prior art that the width of the wiper plate cannot be adaptively adjusted according to the width of the prefabricated part.

[0006] The present solution provides a trowel machine for prefabricated parts, which is achieved by the following specific technical means: it includes a mounting frame, a double-sided horizontal rail is fixed on the top of the mounting frame, and track one and track two are symmetrically arranged on both sides of the double-sided horizontal rail. A plurality of groups of sliders one are slidably provided on the track one, and a group of trowel plates one is fixed on each group of the sliders one. A plurality of groups of sliders two are slidably provided on the track two, and a group of trowel plates two are fixed on each group of the sliders two. The bottom surfaces of the plurality of groups of trowel plates one and the plurality of groups of trowel plates two are located in the same plane, and the overall width of the trowel plates composed of the plurality of groups of trowel plates one and the trowel plates two is adapted to the width of the prefabricated parts.

[0007] Preferred technical solution 1: Multiple groups of the sliders are connected via a scissor mechanism 1, which is used to synchronously control the change of the spacing between the multiple groups of sliders 1.

[0008] Preferred technical solution 2: Multiple groups of the sliders 2 are connected via a scissor mechanism 2, which is used to synchronously control the change of the spacing between the multiple groups of sliders 2.

[0009] Preferred technical solution three: the scissor-type mechanism 1 is composed of multiple groups of folding rod groups 1 connected in sequence, the number of the folding rod groups 1 is equal to the number of the sliding blocks 1 and the positions correspond one to one, and the middle part of the folding rod group 1 is hinged to the sliding block 1.

[0010] Preferred technical solution four: the scissor-type mechanism 2 is composed of multiple groups of folding rod groups 2 connected in sequence, the number of the folding rod groups 2 is equal to the number of the sliding blocks 2 and the positions correspond one to one, and the interconnected ends of two adjacent groups of folding rod groups 2 are connected to the sliding block 2 located between them.

[0011] Preferred technical solution five: a group of sliders one located in the middle of the multiple groups of sliders one is fixed to the middle of track one, and at the same time, the middle of the multiple groups of folding rod groups two are rotatably connected to the limit shaft fixed to the middle of track two, so that the multiple groups of sliders one and the multiple groups of sliders two can maintain a staggered state when the scissors-fork mechanism one and the scissors-fork mechanism two are folded and extended.

[0012] Optimal technical solution six: the scissor-type mechanism one and the scissor-type mechanism two overlap front and back.

[0013] The above structure enables this solution to have the following beneficial effects:

[0014] 1. By adjusting the spacing between the trowel plates 1 and the spacing between the trowel plates 2, the overall width of the trowel plates composed of multiple sets of trowel plates 1 and 2 can be adjusted to match the width of the prefabricated part;

[0015] 2. By setting and connecting the scissor mechanism 1 and the scissor mechanism 2, the two sets of scissor mechanism 1 and the scissor mechanism 2 can control the trowel plate 1 and the trowel plate 2 in a linkage manner, thereby increasing the convenience of adjusting the width of the trowel plate.
