And secondly, a fiber net-shaped structure is formed in the concrete, so that the concrete has the effect of higher tensile strength.

The utility model discloses a kind of planting device of hemp and hairy leaf sainfoin mixed sowing, it is related to hairy leaf sainfoin and hemp mixed sowing technical field, including rack main body, rack main body one side is fixedly installed with multiple seed boxes, multiple seed box middle inner wall is fixedly installed with slope plate, multiple seed box upper inner wall is fixedly installed with second partition plate, multiple seed box inner side wall is fixedly installed with first partition plate, the butt joint gap of similar second partition plate and first partition plate is all provided with feeder.The utility model, the hemp and hairy leaf sainfoin seed mixed well are thrown from the upside of second partition plate, so that seed is slipped down along the gap between slope plate and second partition plate, then by starting drive assembly, so that rotate, and fine sand in cavity is evenly dispersed into seed, so that the gap between hemp and hairy leaf sainfoin is filled, reduce the influence of shape and size difference to stratification, avoid mixed sowing uneven.

The cosmetic packaging bottle comprises a bottle body provided with a bottle opening and used for containing cosmetics and a cover body matched with the bottle opening to seal the bottle body, and the cover body is connected with a brush rod extending into the bottle body from the bottle opening and a brush head fixed to the tail end of the brush rod and used for smearing. The bottle opening is provided with an inner plug with a through hole, the brush rod passes through the through hole and is in transition fit with the through hole, the brush rod is rotationally connected with the cover body, the brush rod is provided with a spiral section, and when the spiral section passes through the through hole, the inner plug acts on the brush rod and drives the brush rod to rotate. According to the cosmetic packaging bottle, when the spiral section passes through the through hole, the inner plug exerts a tangential effect on the spiral section, so that the brush rod rotates, and the brush rod drives the brush head to rotate in the bottle body, so that cosmetics in the bottle body are stirred, and the problem of layering of the cosmetics is solved; and cosmetics which are not used for a long time can be recovered to be in a normal use state.

The utility model relates to the technical field of sewage sedimentation, and discloses a sedimentation tank for sewage treatment, which comprises a tank body, a primary sewage baffle is fixedly connected to the upper part, close to the front side, in the tank body, a primary sliding chute is fixedly connected to the upper end of the middle front side in the tank body, a primary screen is slidably connected in the primary sliding chute, and a secondary screen is slidably connected in the primary screen. A heating cavity is fixedly connected to the lower end of the middle front side in the tank body, a cavity body of the heating cavity penetrates through one side of the tank body, a fixed cover plate is clamped to one side of the outer portion of the heating cavity, a plurality of heating rods are fixedly connected to the inner side of the fixed cover plate at equal intervals, and a secondary dirt baffle is fixedly connected to the middle of the bottom end of the tank body. A secondary sliding groove is fixedly connected to the middle rear side of the interior of the tank body, and a secondary screen is slidably connected into the secondary sliding groove. According to the utility model, firstly, the solid precipitation efficiency is improved through the dirt baffle, solid impurities in sludge are filtered through the primary screen and the secondary screen, and oil-liquid separation in liquid is realized through the heating rod, so that the filtering efficiency is improved.

The invention discloses concrete containing machine-made sand. The concrete is prepared from the following raw materials in parts by weight: 300 to 500 parts of cement, 45 to 60 parts of fly ash, 55 to 75 parts of mineral powder, 600 to 900 parts of fine aggregate, 35 to 45 parts of silica fume, 600 to 660 parts of machine-made sand, 60 to 75 parts of rubber particles, 40 to 50 parts of admixture and 8 to 15 parts of water reducing agent. According to the concrete containing the machine-made sand and the preparation method of the concrete, by adding the fly ash, the mineral powder, the fine aggregate, the silica fume, the rubber particles and the admixture, the tensile strength, the compressive strength and the flexibility of the concrete are enhanced, meanwhile, the cohesiveness of the concrete can be improved, the layering phenomenon of the concrete is improved, and therefore the concrete is not prone to cracking, and the service life of the concrete is prolonged. The anti-seepage concrete has the advantages of improving the crack generation condition of the anti-seepage concrete, reducing the hydration heat of the concrete, replacing the river sand without three-waste discharge, and adding the rubber particles prepared from waste rubber products, thereby having favorable economic and social benefits.

The application discloses an air-laid machine for uniform netting, comprising a frame for providing a supporting installation reference; a cotton feeding unit arranged at one end of the frame for continuously outputting fiber raw materials; and a conveying netting unit arranged at the other end of the frame for providing a bearing surface for fiber netting and conveying a formed fiber net. The application divides the flow guide channel into an upper flow section, a middle flow section and a lower flow section, and sets a fiber guide component in the middle flow section to form a multi-stage continuous fiber guide channel. When the mixed fiber raw materials flow along the flow guide channel, the fiber guide channel can first guide and converge part of the layered fiber raw materials, and then perform secondary deviation correction on the outflow part of the layered fiber raw materials, so that full coverage and continuous guidance mixing of the layered fiber raw materials are realized. Meanwhile, the staggered interval type channel structure of the fiber guide channel will not block the airflow, can effectively avoid the retention, wall-hanging accumulation and channel blockage of the fiber raw materials, and continuously ensures the uniform and stable flow of the fiber airflow.
