Description

Technical Field

[0001] The utility model relates to the technical field of substrate processing, and more specifically, to a substrate mixer. Background Art

[0002] Factory seedling cultivation uses substrate and plug tray as carriers. The substrate is loose, light, and has a low bulk density. It is used in large quantities in factory seedling cultivation. However, due to the above characteristics of the substrate, it is inconvenient to transport and has high costs. Therefore, during the transportation of the substrate, it is usually made into a compressed substrate. The substrate transported to the horticultural base is usually a compressed substrate weighing 50-60kg (approximate size: 95×45×35cm). During the seedling production process, the compressed substrate needs to be decompressed into a loose state to maintain the original fiber structure of the substrate to ensure good air permeability and water retention for good plant growth.

[0003] In this regard, the prior art discloses a mobile matrix decompression and crushing machine (publication number CN213102547 U), which transfers the matrix to the discharge port through a placement bottom plate, a chain group and an extended iron plate arranged in a feed decompression structure, and a rotating scraper to decompress and crush the matrix. Although the design of the prior art facilitates the transmission of the matrix to the discharge port, it is easy to cause the compressed matrix to be blocked at the discharge port, and the rotating scraper cuts at the discharge port, which is easy to destroy the original fiber structure, and the dispersion, decompression and stirring effect of the compressed matrix is ​​not ideal.

[0004] Therefore, it is urgent to design a matrix mixer that can overcome the above-mentioned defects to a certain extent. Utility Model Content

[0032] like Figure 1-4 As shown, the utility model discloses a matrix mixer, which comprises:

[0033] The mixing box 1 is an inverted trapezoidal box with an upper opening and a larger upper part and a smaller lower part;

[0034] A first rotating shaft 2, which is disposed in the mixing box 1, wherein one end of the first rotating shaft 2 is rotatably connected to one end of the mixing box 1, and the other end of the first rotating shaft 2 is rotatably connected to the other end of the mixing box 1;

[0035] A spiral stirring blade 6 is spirally wound along the first rotating shaft 2. When the first rotating shaft 2 drives the spiral stirring blade 6 to rotate, the material inside the spiral stirring blade 6 can be pushed to move from one end of the mixing box 1 to the other end. The outer contour of the spiral stirring blade 6 is set to be sawtooth 3-shaped;

[0036] A discharge pipe, which is connected to a discharge port at the other end of the mixing box 1, the discharge port is located at the bottom wall or the lower end of the side wall of the mixing box 1, and a spiral blade 13 for bringing out the material is arranged in the discharge pipe, and the spiral blade 13 is spirally wound along the second rotating shaft 12;

[0037] The power box 7 is provided with a transmission mechanism, which is respectively connected to the first rotating shaft 2 and the second rotating shaft 12 for driving the spiral stirring blades 6 and the spiral blades 13 to rotate. The spiral stirring blades 6 and the spiral blades 13 drive the materials therein to move in the same direction, that is, the materials move from one end of the mixing box 1 to the other end and are discharged from the discharge pipe.

[0038] The use process of the utility model is as follows: the transmission mechanism of the matrix mixer is started to drive the spiral stirring blades 6 and the spiral blades 13 to rotate, and then the compressed matrix with the outer packaging torn off is put into the mixing box 1 from the upper opening at one end of the mixing box 1 one by one. The compressed matrix contacts the sawtooth 3 on the rotating spiral stirring blade 6 to quickly dissolve the compressed matrix, and is stirred and mixed during the rotation of the spiral stirring blade 6 and gradually moved to the discharge port at the other end of the mixing box 1. The stirred and mixed matrix enters the discharge pipe from the discharge port and is discharged from the discharge pipe under the rotation of the spiral blades 13 in the discharge pipe. A storage container or a transfer vehicle is placed outside the discharge pipe to hold the stirred and mixed matrix for use in the next step of seedling cultivation and planting. The utility model sets the outer contour of the spiral stirring blade 6 to be sawtooth 3-shaped, which is beneficial to the dispersion of the compressed matrix and is not easy to damage the original fiber structure. The dispersed matrix is ​​conducive to mixing in the stirring box 1 and is convenient for spiral transmission out of the discharge pipe, thereby improving the dispersion and stirring efficiency of the compressed matrix, reducing the damage to the original fiber structure of the matrix, improving the dispersion and stirring efficiency, and reducing labor costs.

[0039] On the basis of the above implementation, a plurality of pusher blades 10 are arranged on the first rotating shaft 2 at the discharge port, and the plurality of pusher blades 10 are evenly arranged along the circumference of the first rotating shaft 2. The fixed edge of the pusher blade 10 arranged on the first rotating shaft 2 is parallel to the axial direction of the first rotating shaft 2. The pusher blade 10 is an arc-shaped plate. When the first rotating shaft 2 drives the spiral stirring blade 6 and the pusher blade 10 to rotate, the outward arc surface of the pusher blade 10 is the same as the rotation direction, and the outward arc surface rotates from the bottom to the top of the discharge port, as shown in the arrow direction in the figure as the rotation direction. This design can promote the stirred and dispersed matrix material to enter the discharge port. Under the rotation of the pusher blade 10 and the spiral blade 13, the matrix is ​​not easy to be blocked at the discharge port by one push and one suction, thereby improving efficiency and smoothness. There are four pusher blades 10 shown in the figure, which has a better effect.

[0040] Based on the above implementation, a reinforcing rib 11 is provided in the arc-shaped opening of the pusher blade 10 , one end of the reinforcing rib 11 is connected to the outer end of the pusher blade 10 , and the other end of the reinforcing rib 11 is connected to the first rotating shaft 2 , for reinforcing the arc-shaped pusher blade 10 .

[0041] On the basis of the above implementation, the sawtooth 3 is in the shape of an isosceles triangle, and the height of the sawtooth 3 is 1-1.5 cm, which can not only disperse and stir the compressed matrix, but also help clean the sawtooth and reduce fiber entanglement.

[0042] On the basis of the above implementation, the bottom plate of the mixing box 1 is an arc-shaped plate body to adapt to the rotating outer arc surfaces of the spiral mixing blades 6 and the pushing blades 10 .

[0043] On the basis of the above implementation, a support platform 4 is provided on one side of the opening of the mixing box 1, and a support leg 5 is provided below the support platform 4 to support the support platform 4. The support platform 4 of this design is used to support the compressed matrix whose outer packaging has not been torn open, so that the staff can use a knife to cut the outer packaging and push or pour the compressed matrix into the mixing box 1, which is convenient for operation.

[0044] Based on the above implementation, the discharge pipe is a multi-section detachable connecting pipe body. This design can meet the needs of storage containers or transfer vehicles of different heights, saving transportation labor.

[0045] The specific technical details are designed as follows: the discharge pipe includes a first section discharge pipe 8 and an outer end discharge pipe 9, the outer walls of the first section discharge pipe 8 and the outer end discharge pipe 9 are both provided with matching ear plates 14, the ear plates 14 are provided with matching screw holes 15, one end of the first section discharge pipe 8 is connected to the discharge port of the mixing box 1, and one end of the outer end discharge pipe 9 is connected to the other end of the first section discharge pipe 8 through the ear plate 14. Alternatively, the discharge pipe includes a first-section discharge pipe 8, a second-section discharge pipe and an outer-end discharge pipe 9, and the outer walls of the first-section discharge pipe 8, the second-section discharge pipe and the outer-end discharge pipe 9 are all provided with matching ear plates 14, one end of the first-section discharge pipe 8 is connected to the discharge port of the mixing box 1, the first-section discharge pipe 8 and the second rotating shaft 12 in the second-section discharge pipe are connected by a clamping joint 16, the pipe bodies are connected by the ear plates 14, and the outer-end discharge pipe 9 is connected to the outer end of the second discharge pipe through the ear plates 14; the outer-end discharge pipe 9 is not provided with spiral blades 13, and a cover body with a clamping joint 16 is provided in the center of the outer-end discharge pipe 9 to protect the interface of the middle section of the discharge pipe. By increasing or decreasing the number of middle sections of the discharge pipe as needed, storage containers or transfer vehicles of different heights can be accommodated, saving transportation labor.

[0046] On the basis of the above implementation forms, lamps are arranged on the top of the mixing box 1 and / or the top of the discharge pipe, or a water pipe or a liquid medicine pipe is connected above the mixing box 1, which can increase the use function and effect of the matrix mixer.

[0047] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
