Description

Technical Field

[0001] The utility model relates to the technical field of full-nutrient cultivation matrix raw material screening devices, in particular to a full-nutrient cultivation matrix raw material screening device. Background Art

[0002] The cultivation matrix originally originated from the concept of soilless cultivation, which means that the soil environment around crops has deteriorated, seriously affecting the yield and quality of crops. People turned to look for alternatives, using solid matrices (mediums) to fix plant roots and absorb nutrients and oxygen through the matrix. The so-called cultivation matrix refers to a solid medium that replaces soil to provide mechanical support and material supply for crops.

[0003] When the existing full-nutrient cultivation matrix raw material screening device is installed and used, it cannot discharge the unqualified materials of size from the screen, causing the materials to accumulate on the screen, affecting the screening of subsequent feed; since the unqualified materials cannot be crushed again, the user is required to manually collect the unqualified materials and then put them into the grinder. This series of processes reduces the screening efficiency of the raw materials; since the screening rate of the materials cannot be controlled, the materials will also accumulate on the screen, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a full-nutrient cultivation matrix raw material screening device. Utility Model Content

The fourth motor 14 drives the driving gear 13 to rotate, and the driving gear 13 drives the driven gear 12 to rotate, so that the two sets of cutting rods 18 operate at the same time to cut the material. After the material falls on the filter screen 20, the cylinder 17 drives the push plate 21 to move left and right to flatten the material for easy screening.

When there is no material coming out of the discharge port 22 inside the screening box 1, the cylinder 17 drives the push plate 21 to move to the right, and pushes the material that has not been screened on the surface of the filter screen 20 to the channel 11, and enters the guide frame 2 from the channel 11. The first motor 5 drives the built-in auger shaft 6 to rotate, and the built-in auger shaft 6 drives the material to move upward, so that the material passes through the upper end of the cutting rod 18 again, is cut by the cutting rod 18 and screened again.

[0027] It should be noted that the utility model is a full-nutrition cultivation matrix raw material screening device.

The fourth motor 14 drives the driving gear 13 to rotate, and the driving gear 13 drives the driven gear 12 to rotate, so that the two sets of cutting rods 18 operate at the same time to cut the material. After the material falls on the filter screen 20, the cylinder 17 drives the push plate 21 to move left and right to flatten the material for easy screening.

[0028] The third motor 10 drives the worm 16 to rotate, the worm 16 drives the turbine 19 to rotate, the turbine 19 drives the cleaning rod 15 to rotate, so that the protrusions on the surface of the cleaning rod 15 intermittently contact the lower end surface of the filter screen 20, thereby driving the filter screen 20 to vibrate slightly, thereby accelerating the screening efficiency of the material. When there is no material coming out of the discharge port 22 inside the screening box 1, the cylinder 17 drives the push plate 21 to move to the right, and pushes the material that has not been screened on the surface of the filter screen 20 to the channel 11, and enters the guide frame 2 from the channel 11. The first motor 5 drives the built-in auger shaft 6 to rotate, and the built-in auger shaft 6 drives the material to move upward, so that the material passes through the upper end of the cutting rod 18 again, is cut by the cutting rod 18 and screened again.
