Description

Technical Field

[0001] This utility model belongs to the field of fertilizer blending technology, specifically relating to a microbial fertilizer blending device. Background Technology

[0002] Microbial fertilizers, also known as bio-fertilizers or microbial fertilizers, are products containing specific living microorganisms applied to agricultural production. The secondary metabolites produced during the growth and metabolism of these microorganisms increase the supply of nutrients to plants, thereby promoting plant growth and improving the quality of agricultural products. Compound microbial fertilizers are made by mixing two or more types of microorganisms or one type of microorganism with other nutrients, which can enhance the fertilizer's effectiveness.

[0003] Existing technologies disclose microbial fertilizer mixing devices or devices that can be used for microbial fertilizer mixing. For example, patent CN212417700U discloses a solid microbial fertilizer compounding device, including a first mounting plate, a second mounting plate, a feeding mechanism disposed on the top surface of the second mounting plate, and a stirring mechanism disposed between the second mounting plate and the first mounting plate. The stirring mechanism mixes the crushed poultry and livestock manure with the microbial fertilizer, making the microbial fertilizer and poultry and livestock manure come into more thorough contact, thereby improving the production efficiency of the microbial fertilizer.

[0004] Undeniably, the solid microbial fertilizer compounding device disclosed in this patent can indeed achieve the above-mentioned effects, but it still has some shortcomings: the second rotating shaft in its stirring mechanism only drives the stirring blade shaft to rotate, the stirring blade cannot move up and down, and the stirring blade can only contact and stir the material in its rotation path. The stirring effect and efficiency need to be further improved.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a microbial fertilizer mixing device to solve the problems existing in the solid microbial fertilizer compounding device in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A microbial fertilizer mixing device, comprising:

[0009] A mixing tank, which is supported on the ground;

[0010] The tank cover is fixed to the top of the mixing tank by bolts. A vertical transmission sleeve is installed at the center of the tank cover, and the bottom of the transmission sleeve penetrates through the tank cover.

[0011] A drive shaft is inserted into the drive sleeve and slides in a guide engagement with the drive sleeve. An inclined disc is fixed near the top of the drive shaft. The bottom of the drive shaft extends out from the bottom of the drive sleeve. Multiple stirring plates are evenly spaced on the portion of the drive shaft located inside the mixing tank.

[0012] A support plate is fixed to the top of the can lid. Two mounting shafts are fixed vertically at intervals on the side of the support plate near the drive shaft. Limiting rollers that rotate with the mounting shafts are mounted on the mounting shafts. The outer edge of the disc is located between the two limiting rollers.

[0013] A driving component that connects to the transmission sleeve and drives the transmission sleeve to rotate.

[0014] Preferably, the bottom of the mixing tank is connected to a discharge pipe, and a switch valve is installed on the discharge pipe.

[0015] Preferably, a seated bearing is mounted on the outside of the transmission sleeve and rotates therewith, and the seated bearing is fixed on the can cover.

[0016] Preferably, the transmission sleeve has multiple number "7" shaped stirring rods evenly spaced on the side wall inside the mixing tank.

[0017] Preferably, the cross-section of the drive shaft is a regular hexagon, and the hollow structure of the drive sleeve corresponds to the drive shaft.

[0018] Preferably, the top of the stirring plate is tilted upwards.

[0019] Preferably, the driving component includes a drive motor fixed to the outer wall of the mixing tank with its output shaft pointing vertically upward, a drive wheel fixed to the output shaft of the drive motor, a driven wheel fixed to the top of the transmission sleeve, and a transmission belt connecting the drive wheel and the driven wheel.

[0020] Preferably, the driving wheel and the driven wheel are pulleys, and the transmission belt is a belt.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention features a cooperating transmission sleeve, transmission shaft, and limiting roller. When the drive motor in the drive unit rotates the transmission sleeve, the transmission shaft drives the disc located on its top to rotate. Since the outer edge of the disc is located between two rollers and is tilted, the outer edge of the disc moves up and down reciprocally under the action of the limiting roller. This, in turn, drives the mixing plate to rotate circumferentially and move up and down reciprocally. The tilted position of the mixing plate increases the probability of contact and mixing with materials at different locations, resulting in more uniform mixing and further improving the mixing effect and efficiency. The entire device has a novel structural design and is suitable for mixing microbial fertilizers and other materials. Attached Figure Description

[0029] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example

[0031] See appendix Figure 1-4 A microbial fertilizer mixing device, comprising:

[0032] Mixing tank 1 is supported on the ground. A material pipe 11 is connected to the bottom of the mixing tank 1, and a switch valve 12 is installed on the material pipe 11.

[0033] The tank cover 2 is bolted to the top of the mixing tank 1. A vertical transmission sleeve 21 is installed at the center of the tank cover 2, and the bottom of the transmission sleeve 21 penetrates the tank cover 2. The transmission sleeve 21 is installed as follows: a seated bearing 22 is installed on the outside of the transmission sleeve 21 and rotates with it. The seated bearing 22 is fixed on the tank cover 2. It should be noted that the inner ring of the seated bearing 22 is fixedly connected to the transmission sleeve 21. In addition, a discharge port sealed with a sealing cap 23 is provided at the eccentric position of the tank cover 2 (not shown in the attached figure). In this embodiment, multiple number "7" shaped stirring rods 24 are evenly spaced and fixed on the side wall of the mixing tank 1 inside the transmission sleeve 21.

[0034] The transmission shaft 3 is inserted inside the transmission sleeve 21 and slides in a guide fit with the transmission sleeve 21. Specifically, the cross-section of the transmission shaft 3 is a regular hexagon, and the hollow structure of the transmission sleeve 21 corresponds to the transmission shaft 3. An inclined disc 31 is fixed near the top of the transmission shaft 3. The bottom of the transmission shaft 3 extends out from the bottom of the transmission sleeve 21. Multiple stirring plates 32 are evenly spaced on the part of the transmission shaft 3 located inside the mixing tank 1, and the top of the stirring plates 32 is inclined upward.

[0035] A support plate 4 is fixed to the top of the can lid 2. Two mounting shafts 41 are fixed at intervals on the side of the support plate 4 near the drive shaft. A limiting roller 42 that rotates with the mounting shaft 41 is mounted on the mounting shaft 41. The outer edge of the disc 31 is located between the two limiting rollers 42.

[0036] The drive component 5 is a drive unit that drives the transmission sleeve 21 to rotate. Specifically, the drive component 5 includes a drive motor 51 fixed to the outer wall of the mixing tank 1 with its output shaft pointing vertically upward, a drive wheel 52 fixed to the output shaft of the drive motor 51, a driven wheel 53 fixed to the top of the transmission sleeve 21, and a transmission belt (not shown in the figure) that drives the drive wheel 52 and the driven wheel 53. In this embodiment, the drive wheel 52 and the driven wheel 53 are pulleys, and the transmission belt is a belt.

[0037] In use, the material to be mixed enters the mixing tank 1 through the discharge port at the eccentric position of the tank cover 2. The drive motor 51 is connected to an external power source. When the drive motor 51 is working, it drives the drive wheel 52 to rotate. The drive wheel 52 drives the driven wheel 53 to rotate via a transmission belt. The driven wheel 53 drives the transmission sleeve 21 to rotate. Since the cross-section of the transmission shaft 2 is a regular hexagon, and the hollow structure of the transmission sleeve 21 corresponds to that of the transmission sleeve 3 (i.e., the hollow structure of the transmission sleeve 3 is also a regular hexagon), when the transmission sleeve 21 rotates, it drives the transmission shaft 21 to rotate. The transmission shaft 21 drives the disc 31 to rotate. Since the outer edge of the disc 31 is limited between two rollers 42, and the disc 3 is in an inclined state, the outer edge of the disc 3 will move up and down reciprocally under the action of the limiting rollers 42. The up and down movement of the disc 3 drives the transmission shaft 3 to move up and down reciprocally. In this way, through a series of transmissions, the drive motor 52 drives the transmission shaft 3 to rotate circumferentially and move up and down reciprocally simultaneously.

[0038] When the drive shaft 3 rotates in a circular motion and moves up and down reciprocally, it drives the stirring plate 32 to rotate in a circular motion and move up and down reciprocally. Since the stirring plate 32 is tilted, this increases the probability of the stirring plate 32 contacting and stirring materials at different locations, resulting in more uniform mixing and further improving the stirring effect and efficiency. Secondly, the rotation of the drive sleeve 21 drives the stirring rod 24 to rotate, and the stirring rod 24 also plays a stirring role.

[0039] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
