Abstract

(57) [Summary] [Purpose] When taking out fresh concrete from the rotating drum of a concrete mixer truck, the purpose is to remove foreign substances generated in the drum to obtain high quality fresh concrete and to improve safety. And [Structure] A substantially rectangular outer shell is provided, and its internal structure is composed of a rod (2), a lattice body group (11) formed vertically and horizontally by the rod body (2), and the lattice body group (11). A gate type (8) vertically attached to one side, a handle (3) connected to the gate type (8), and the gate type (8).
And a fitting portion (6) rotatably attached to each end of the rod (2) in the longitudinal direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In this device, obstacles in placing concrete, such as concrete lumps adhering to the inside of the concrete mixer truck peeled off and were discharged together with the concrete, were mounted on the inner surface of the mixer truck "scoop". It is prevented by a foreign matter removal device and is used in all similar industries.

[0002]

[Prior art]

 Conventionally, as this type of technique, there is no known technique that attempts to remove the exfoliated material in the drum that occasionally occurs when unloading fresh concrete from a concrete mixer truck. This is because strict quality control (transportation control) based on JIS has been performed inside the concrete mixer truck as well as the manufacturing technology in the raw concrete plant, and as a result of the premise that there is no foreign matter, the means for removing foreign matter. , Because the development of the method was neglected.

[0003]

[Problems to be solved by the device]

 In this way, the concrete mixer truck does not have a foreign matter removal device when unloading fresh concrete, so it is extremely rare, for example, when directly placing it from the mixer truck. On flat roads or simple civil engineering, foreign matter accidentally mixed in fresh concrete may be overlooked and placed. In addition, in recent years, the speeding up and labor saving of the driving method have been promoted, and as a countermeasure, the driving method using the pressure pump is the mainstream. For this reason, if foreign matter is mixed in, depending on its size and shape, the press-fitting and feeding device of the ready-mixed concrete pumping vehicle will be clogged, or the pumping pipe will be ruptured, resulting in a personal injury. You can also see some cases coming. The present invention is intended to solve the above problems.

[0004]

[Means for Solving the Problems] In order to solve the above-mentioned problems, a substantially rectangular outer shell is provided, and the internal structure thereof is a rod (2) (2a) (2b) and this rod (2) ( 2a) and (2b) are provided in a vertical state with respect to a required grid body group (11) which is continuously formed vertically and horizontally, and one side of the grid body group (11). A gate type (8), a handle (3) with a hook that is vertically connected in the vicinity of a substantially central portion of the gate type (8), and a rod (2) to which the gate type (8) is attached. A rod (2) that can be fitted to the left and right ends of the lattice body (6), and the other end of the lattice group (11) in the longitudinal direction. A screen grid device for removing foreign matter, comprising a protrusion (4) bent in a substantially vertical state in a direction opposite to the gate type (8).

[0005]

[Action]

 Since it is configured as described above, the handle is opened (when not used) or closed (when used) with the rod fitted to the fitting portion rotatably attached to the left and right scoops as the starting point. It is possible to remove the desired foreign matter and the like by selectively using them.

[0006]

【Example】

 An embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5 of the drawings. The rod (2) (2a) is provided with a substantially rectangular outer shell and its inner structure is made of a reinforcing bar, a flat bar or the like. (2b), a required grid body group (11) formed by the rods (2), (2a) and (2b) continuously in the left-right, vertical and horizontal directions, and one side of the grid body group (11) In contrast to this, a gate type (8) that is vertically engaged, a hooked handle (3) that is vertically connected in the vicinity of a substantially central portion of the gate type (8), and the gate type (8). ) Is attached to the rod (2), which can be fitted to the left and right ends of the rod (2) in the longitudinal direction. A screen grease for removing foreign matter, which includes a protrusion (4) bent in a substantially vertical state in a direction opposite to the gate type (8) with respect to the left and right in the longitudinal direction of the other end. De devices. When using this screen grid device for removing foreign matter, the fittings that are rotatably attached to the left and right "scoops" that are installed in advance near the raw concrete discharge port of the rotating drum of the concrete mixer truck. Starting from the rod fitted in the joint, the handle can be used as open (when not in use) or close (when in use) to remove desired foreign substances and obtain good quality concrete. You can do it.

[0007]

[Effect of device]

 Since this foreign matter removing screen grid device is constructed as described above, foreign matters can be completely removed, so that high quality ready-mixed concrete can be obtained and, in particular, work for concrete pouring work in deep layers, etc. This has the great effect of improving the safety and ensuring safety.
