Description

Technical Field

[0001] The invention relates to the technical field of fermentation bacterial fertilizer preparation equipment, in particular to a large-scale automatic bacterial fertilizer fermentation rack. Background Art

[0002] Fermented bacterial fertilizer is a kind of fertilizer containing beneficial microorganisms. It improves soil structure, increases soil fertility and promotes plant growth through the life activities of microorganisms. The preparation of fermented bacterial fertilizer generally includes sterilization before fermentation, spraying nutrients, spraying bacterial liquid, fermentation and drying. The existing preparation of fermented bacterial fertilizer has the following problems:

[0003] 1. Steam sterilization or chemical sterilization is generally used for equipment sterilization before fermentation. Steam sterilization requires airtightness of the plant and has good sterilization effect, but it is inconvenient to operate; chemical sterilization has residual problems and has an adverse effect on fermentation fertilizer. In addition, the duration of sterility after conventional sterilization is short, and the fermentation equipment is easily contaminated again.

[0004] 2. Nutrients and bacterial liquid are generally sprayed manually, which has low efficiency and poor spraying effect.

[0005] 3. During fermentation, materials are usually piled on the ground to form a pile. The thickness of the pile is difficult to control. If the pile is too large, it will easily lead to poor oxygen supply to the internal materials. It is necessary to turn the pile regularly every 2 to 3 days, which increases labor costs, and the vertical space of the factory is insufficiently utilized, resulting in relatively limited output.

[0006] 4. Fermentation temperature and humidity are difficult to maintain during fermentation.

[0007] 5. The fermentation material needs to be sterilized in advance, and the steps are relatively complicated.

[0008] In view of this, how to provide a fermentation fertilizer preparation device that can partially or completely solve the above problems is an issue that technical personnel in this field urgently need to solve. Summary of the invention

[0021] a second nozzle, the second nozzle being evenly arranged on the mounting frame, the second nozzle corresponding to the shallow plate;

[0022] A second connecting pipe, wherein one end of the second connecting pipe is connected to the second nozzle, and the other end of the second connecting pipe extends outside the shallow dish and is connected to the bacterial liquid storage tank.

[0023] Furthermore, the first nozzle is located on the left and right sides of the mounting frame, the second nozzle is located on the front and rear sides of the mounting frame, the first connecting pipe is led out from the left or right side of the mounting frame, and the second connecting pipe is led out from the front or rear side of the mounting frame.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] The embodiment of the present invention provides a large-scale automated bacterial fertilizer fermentation rack, comprising: a mounting rack 1, wherein the middle portion of the mounting rack 1 penetrates through the upper and lower surfaces to form a mounting hole 101, the lower opening of the mounting hole 101 is fixedly connected to a shallow plate 2, the shallow plate 2 is adapted to the shape of the mounting hole 101, and can be inserted into the mounting hole 101 from top to bottom, and the lower surface of the shallow plate 2 is a mesh plate 201; a lifting mechanism, wherein there are multiple mounting racks 1 and they are arranged in sequence along the longitudinal direction, and the lifting mechanism is connected to the multiple mounting racks 1 in a one-to-one correspondence and can respectively drive the mounting racks 1 to move along the longitudinal direction.

[0041] like Figure 1 As shown, the lifting mechanism includes: a base 3, which is located below the mounting frame 1; a hydraulic cylinder 4, which is fixedly arranged on the base 3, and a hydraulic rod of the hydraulic cylinder 4 is fixedly connected to the lowest mounting frame 1, or passes through the lower mounting frame 1 and is fixedly connected to the upper mounting frame 1. Figure 1 In this embodiment, there are three mounting frames 1, of which the bottom mounting frame 1 is fixedly arranged on the base 3 through a support rod (not shown in the figure), and there are four groups of hydraulic cylinders 4. The hydraulic rods of the two middle groups of hydraulic cylinders 4 penetrate the bottom mounting frame 1 and are fixedly connected to the middle mounting frame 1. The hydraulic rods of the two outer groups of hydraulic cylinders 4 penetrate the bottom and middle mounting frames 1 and are fixedly connected to the top mounting frame 1. The above four groups of hydraulic cylinders 4 can respectively drive the middle mounting frame 1 and the top mounting frame 1 to move longitudinally, adjust the distance between adjacent mounting frames 1, and increase the contact area between materials and oxygen.

[0042] like Figure 2As shown, it also includes: a first nozzle 5, the first nozzle 5 is evenly arranged on the mounting frame 1, and the first nozzle 5 corresponds to the shallow dish 2; a first connecting pipe 6, one end of the first connecting pipe 6 is connected to the first nozzle 5, and the other end extends to the outside of the mounting frame 1 and is connected to the nutrient solution storage tank, and the first nozzle 5 is spaced apart from the hydraulic rod; a second nozzle 7, the second nozzle 7 is evenly arranged on the mounting frame 1, and the second nozzle 7 corresponds to the shallow dish 2; a second connecting pipe 8, one end of the second connecting pipe 8 is connected to the second nozzle 7, and the other end extends to the outside of the mounting frame 1 and is connected to the bacterial solution storage tank. In this embodiment, the first nozzle 5 is located on the left and right sides of the mounting frame 1, and the second nozzle 7 is located on the front and back sides of the mounting frame 1 ( Figure 2 Only the second nozzle 7 located at the rear side is shown in the figure, the first connecting pipe 6 is led out from the right side of the mounting frame 1, and the second connecting pipe 8 is led out from the rear side of the mounting frame 1.

[0043] A plurality of first connecting tubes 6 are connected to the nutrient solution storage tank through a first connecting hose, or a first connecting head is provided on the first connecting tube 6; a plurality of second connecting tubes 8 are connected to the bacterial liquid storage tank through a second connecting hose, or a second connecting head is provided on the second connecting tube 8. When the first connecting tube 6 and the second connecting tube 8 are connected to the nutrient solution storage tank and the bacterial liquid storage tank respectively through the first connecting hose and the second connecting hose, liquid can be transported to each of the first connecting tubes 6 and the second connecting tube 8 at the same time. After the transport is completed, the first connecting hose and the second connecting hose can move longitudinally with the mounting frame 1. When the first connecting tube 6 and the second connecting tube 8 are connected to the nutrient solution storage tank and the bacterial liquid storage tank respectively through the first connecting head and the second connecting head, each mounting frame 1 and the shallow tray 2 need to be connected in sequence from top to bottom, and the bacterial liquid and nutrient solution are sprayed on the corresponding material. After the spraying is completed, the mounting frame 1 is moved up to connect the next mounting frame 1 and the shallow tray 2, and the bacterial liquid and nutrient solution are sprayed again.

[0044] like Figure 4 As shown, in some other embodiments, the first connecting hoses on different mounting racks 1 can be connected sequentially from top to bottom, and the nutrient solution storage tank can simultaneously deliver nutrient solution to multiple first connecting hoses. Similarly, the second connecting hoses on different mounting racks 1 can be connected sequentially from top to bottom, and the bacterial solution storage tank can simultaneously deliver bacterial solution to multiple second connecting hoses, thereby reducing manual labor intensity.

[0045] like Figure 2 As shown, the inner side of the shallow dish 2 and the bottom mesh plate 201 are provided with electric heating wires 9, and the maximum heating temperature of the electric heating wires 9 is 300° C. The mesh aperture of the second mesh plate 201 is 74 μm.

[0046] The specific working process is as follows:

[0047] 1. In the initial state, each mounting rack 1 is located at the lowest position, a shallow tray 2 is placed in each mounting rack 1, and the heating device is started to heat the equipment, remove the residual materials of the previous batch of fermentation and sterilize, and after completion, the materials are placed in the shallow tray 2.

[0048] 2. Start the hydraulic cylinder 4 and lift each mounting frame 1 upward in turn, keeping a reasonable distance between each mounting frame 1.

[0049] 3. After the electric heating wire is started to sterilize the base material, the nutrient solution is sprayed onto the material in each shallow tray 2 through the first connecting hose and the first nozzle 5. The bacterial solution is sprayed onto the material in each shallow tray 2 through the second connecting hose and the second nozzle 7.

[0050] 4. Start fermentation and continue to culture at a suitable constant room temperature for 12 days. After the fermentation is completed, start the electric heating wire again to dry the material, set the drying conditions according to the characteristics of the strain, and after the drying is completed, lower each mounting rack 1 in turn to collect the fermented material in the mounting rack 1.

[0051] Example 2

[0052] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the mounting frame 1 and the leftmost side of the shallow dish 2 are both arranged as an openable and closable frame structure, the first nozzle 5 is not arranged on the frame on the left side of the mounting frame 1, and at the same time, the spraying amount of the first nozzle 5 located on the right side of the mounting frame 1 is increased, and the heating wire 9 is independently arranged on the frame on the left side of the shallow dish 2.

[0053] A push plate mechanism 10 (including a driving rod) is arranged in the shallow tray 2. When the fermentation of the material is finished, the frame structure on the left is opened, and the material is pushed out from right to left by the push plate mechanism 10. A lifting assembly can be arranged below the push plate mechanism 10, and the lifting assembly drives the push plate mechanism 10 to move up and down along the height direction of the shallow tray 2, so as to achieve the effect of adjusting the thickness of the pushed material.

[0054] Compared with Example 1, this embodiment can realize automatic discharging and automatic adjustment of the thickness of the fermentation material. The nutrient solution is sprayed by the first nozzle 5 on the right. The first nozzle 5 can be installed with rotating parts such as ball bearings. The spraying angles of multiple first nozzles 5 can be adjusted to ensure spraying uniformity.

[0055] Example 3

[0056] Compared with Example 2, in this embodiment, each mounting frame 1 is provided with a weighing display device, which can directly peel and weigh the weight of the material added to the shallow plate 2, so that the spraying amount of the nutrient solution can be calculated according to the weight of the material, which can avoid the problem of excessive nutrient solution spraying and overflowing from the bottom.

[0057] In addition, a solution of spraying the nutrient solution layer by layer from top to bottom can be adopted, and the nutrient solution leaking from the upper shallow tray 2 can fall into the lower shallow tray 2, which can maximize the use of the nutrient solution and avoid the problem of nutrient solution waste.

[0058] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0059] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
