[0002] Seedling cultivation is the starting point of forestry production. Container seedlings have the advantages of not damaging the root system and having a high survival rate. One of the most scientific and reasonable seedling cultivation technologies in the forestry industry at home and abroad is container seedling cultivation. Forestry container seedling cultivation is to put the well-proportioned culture medium into the container and then carry out the tree seedling cultivation operation. At present, the production of seedling containers mainly adopts manual, automated and mechanized production methods. The research and development of new seedling containers and their forming machines have great practical significance for the development of my country's forestry construction projects and fast-growing and high-yield forest projects.

[0003] When the seedling container forming machine is working, it is necessary to fill more than 2 / 3 of the nutrient soil in the hopper before starting the equipment, so as to add soil into the hopper after mixing. During the feeding process, the nutrient soil is prone to sink due to its own gravity, causing the soil to stick again, thus forming large soil lumps and affecting the subsequent feeding work. Therefore, in view of this, a hopper quantity control structure is provided to solve the above problem. Utility Model Content

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0031] Example:

[0032] like Figure 1 , 2 As shown, the utility model provides a hopper quantity control structure, including a hopper body 101 that is in the shape of an inverted cone and hollow, the hopper body 101 is provided with a feed port 102 that is connected thereto, a first valve 103 is provided at the connection between the feed port 102 and the hopper body 101, a discharge assembly is provided at the bottom of the hopper body 101, the discharge assembly includes a discharge port 105 that is connected to the hopper body 101, and a second valve 104 is provided at the connection between the discharge port 105 and the hopper body 101.

[0033] When in use, materials can be fed into the hopper body 101 through the feed port 102, and the feeding can be controlled by the first valve 103. An observation plate 106 is provided on the side wall of the hopper body 101. The observation plate 106 extends into the hopper body 101 and is flush with the inner wall. The observation plate 106 is made of a transparent material, and a scale line 107 is provided on the observation plate 106. The volume of the material in the hopper body 101 can be known through the observation plate 106 and the scale line 107 above it, so as to facilitate timely control of the start and stop of the first valve 103 to quantitatively supply the material. And the material in the hopper body 101 can enter the seedling container forming machine through the discharge port 105 by controlling the opening and closing of the second valve 104.

[0034] like Figure 2 , 3 As shown, in this embodiment, a support frame 201 is provided on the hopper body 101, a rotatable mounting frame 203 is provided on the support frame 201, a plurality of sets of spiral stirrers 301 are rotatably provided on the mounting frame 203, the axis of the spiral stirrer 301 is parallel to the generatrix of the hopper body 101, the spiral stirrer 301 is in contact with the inner wall of the hopper body 101, a driving mechanism connected to the plurality of sets of spiral stirrers 301 is provided on the support frame 201, and the spiral stirrer 301 can be driven to rotate along its axis and revolve along the axis of the hopper body 101 through the driving mechanism. The driving mechanism includes a driving motor 202 fixedly provided on the support frame 201, the output shaft of the driving motor 202 is connected to the mounting frame 203, a bevel gear 304 is provided on the spiral stirrer 301, a bevel gear ring 204 is provided at the bottom of the support frame 201, and the bevel gear ring 204 is meshed with the bevel gear 304.

[0035] The drive motor 202 can be controlled to start and drive the mounting frame 203 to rotate. During the rotation process, the mounting frame 203 can drive the spiral agitator 301 installed above it to revolve along the output shaft of the drive motor 202. During the revolution of the spiral agitator 301, the engagement between the bevel gear 304 and the bevel gear ring 204 can drive the spiral agitator 301 to be arranged. The bottom spacing of multiple groups of spiral agitators 301 is reduced, so that it is convenient to fully break up the raw materials such as nutrient soil in the inverted frustum cone hopper body 101, and effectively prevent the materials in the hopper body 101 from agglomerating.

The spiral stirrers 301 can fully stir the hopper body 101 during the movement. The soil lumps in the hopper body 101 are broken, and because the hopper body 101 is in the shape of an inverted frustum, the axis of the spiral agitator 301 is parallel to the generatrix of the hopper body 101, so that the nutrient soil at any position will contact the spiral agitator 301 when discharging, thereby effectively preventing the nutrient soil, fertilizer and other raw materials in the hopper body 101 from falling due to their own gravity and sticking again, avoiding the nutrient soil from forming large soil lumps and affecting the subsequent feeding work, and there is no need to manually break up the nutrient soil lumps, which effectively improves the production efficiency.
