Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a concrete quantitative supply device. Background Art

[0002] Concrete is a general term for engineering composite materials that are bonded into a whole by cementitious materials. The term concrete usually refers to cement concrete that is made by mixing cement as the cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion.

[0003] However, the existing concrete quantitative supply mechanism generally adopts the method of completely fitting iron and iron to perform fitting friction, or replaces the materials to reduce the friction coefficient between the materials, but the friction of sand and gravel on the materials cannot be avoided, and the life of the materials is greatly affected. Utility Model Content

[0007] Preferably, a support is fixedly connected to the outside of the driving cylinder.

[0008] Preferably, a cylinder joint is fixedly connected to the bottom of the middle slide plate, and the cylinder joint is rotatably connected to the output end of the driving cylinder.

[0009] Preferably, a plurality of symmetrically arranged support rods are fixedly connected to both sides of the middle slide plate, and the tops of the plurality of support rods are fixedly connected via fixing rods.

[0010] Preferably, the fixing rod is rotatably connected to a plurality of track upper pressure wheels and track side pressure wheels corresponding to the track.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, the original contact between iron plates and iron plates is changed to the contact between resin rings and iron plates, and the resin plates are more wear-resistant and have a longer service life, thereby effectively ensuring the service life of the quantitative supply mechanism;

[0013] 2. In the utility model, when the driving cylinder is at the rear limit, the feed port flange and the metering cylinder are concentric, so that the raw materials can be introduced into the metering cylinder. Then the driving cylinder works to move the middle slide plate and the metering cylinder to the front limit, so that the metering cylinder and the unloading bottom plate are aligned. In this process, the fine sand in the concrete will penetrate to a certain extent and can be effectively discharged from the friction surface between the wear-resistant resin ring and the middle slide plate, thereby improving the service life of the middle slide plate and the upper cover plate.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2 A concrete quantitative supply device includes a driving cylinder 10, a mounting frame 14 and a track 13. The outside of the driving cylinder 10 is fixedly connected with a support 11 to facilitate the installation and fixing of the driving cylinder 10. The track 13 is fixedly connected to the inside of the mounting frame 14. The track 13 is fixedly connected with an upper cover plate 2 for supporting a feed inlet flange 1. The top of the upper cover plate 2 is fixedly connected with the feed inlet flange 1 for introducing materials.

[0019] In this embodiment, an intermediate slide plate 3 is slidably connected in the track 13, which is used to drive the metering cylinder 7 to slide. A cylinder joint 12 is fixedly connected to the bottom of the intermediate slide plate 3, which is used to drive the intermediate slide plate 3 to slide. The cylinder joint 12 is rotatably connected to the output end of the driving cylinder 10. A plurality of symmetrically arranged support rods 15 are fixedly connected on both sides of the intermediate slide plate 3 to support a fixed rod 16. The tops of the plurality of support rods 15 are fixedly connected through the fixed rod 16. A plurality of track upper pressure wheels 8 and track side pressure wheels 9 corresponding to the track 13 are rotatably connected to the fixed rod 16 to reduce the friction loss between the fixed rod 16 and the track 13.

[0020] In this embodiment, a plurality of balancing resin washers 6 are fixedly connected to the top of the middle slide 3 to reduce the friction between the middle slide 3 and the upper cover plate 2. The top of the balancing resin washers 6 is in contact with the bottom of the upper cover plate 2. A wear-resistant resin ring 5 corresponding to the feed port flange 1 is fixedly connected to the top of the middle slide 3 to increase the service life of the middle slide 3 and the upper cover plate 2. The output end of the driving cylinder 10 is fixedly connected to the bottom of the middle slide 3 to drive the middle slide 3 to slide.

[0021] In this embodiment, a metering cylinder 7 is fixedly inserted on the middle slide plate 3, and a discharge bottom plate 4 is fixedly connected to the inner bottom of the mounting frame 14. The discharge bottom plate 4 is provided with a discharge port corresponding to the metering cylinder 7 to facilitate the discharge of the measured material.

[0022] In this embodiment, when the driving cylinder 10 is at the rear limit, the feed port flange 1 and the metering cylinder 7 are concentric, so that the raw materials can be introduced into the metering cylinder 7, and then the driving cylinder 10 works to move the middle slide 3 and the metering cylinder 7 to the front limit, so that the metering cylinder 7 and the unloading bottom plate 4 are aligned. In this process, the fine sand in the concrete will penetrate to a certain extent and can be effectively discharged from the friction surface between the wear-resistant resin ring 5 and the middle slide 3, thereby improving the life of the middle slide 3 and the upper cover plate 2.

[0023] In this embodiment, the original contact between iron plates and iron plates is changed to the contact between resin rings and iron plates, and the resin plates are more wear-resistant and have a longer service life, thereby effectively ensuring the service life of the quantitative supply mechanism.
