Description

Technical Field

[0001] The invention relates to the technical field of bacteria-carrying mixing and stirring preparation, and specifically provides bacteria-carrying mixing and stirring preparation equipment for preventing and controlling borer pests. Background Art

[0002] Using mixed and stirred carrier bacteria to control corn borer pests is an effective biological control method. The specific method of preparing the carrier bacteria is as follows: first, select pathogens with high toxicity to target pests (such as corn borers), such as Beauveria bassiana, Metarhizium anisopliae or Bacillus thuringiensis, and then select suitable carrier materials, such as corn flour, wheat bran, sawdust, activated carbon, etc. The function of the carrier is to increase the adhesion and dispersibility of the pathogens.

[0003] Then, according to the required dosage, weigh an appropriate amount of pathogen powder and slowly add it to an appropriate amount of water, slowly stir it to fully dissolve it and form a uniform suspension. According to the required dosage, weigh an appropriate amount of carrier material, and slowly pour the prepared pathogen suspension into the carrier material, use a blender to fully stir the pathogen suspension and the carrier material to ensure that the pathogen is evenly attached to the carrier, and the mixed material should maintain appropriate humidity, neither too dry nor too wet, and be kneaded into a ball by hand, and the purpose can be achieved by being able to disperse after being loosened. Finally, the mixed bacteria-carrying material is loaded into a bag or container with good air permeability, and the bacteria-carrying material is directly spread on the root or stem of the crop or mixed into the soil when used.

[0004] However, in the above-mentioned mixed stirring and preparing process of the carrier bacteria for controlling stem borer pests, a traditional stirring mechanism is used to stir the pathogen suspension and the carrier material, and it does not have the function of pressing down and discharging the pathogen suspension and the carrier material stirred and mixed in the mixer. After the pathogen suspension and the carrier material are stirred and mixed, the pathogen suspension and the carrier material in the mixer need to be pressed down and discharged by an external downward pressing and pushing device, which not only increases the preparation cost and the space occupied by the preparation equipment, but also reduces the continuity and efficiency of the mixed stirring and preparing process of the carrier bacteria for controlling stem borer pests.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] See also Figure 1 A bacteria-carrying mixing and stirring preparation device for controlling stem borer pests includes: a supporting platform 1 and a mixing barrel 2. The supporting platform 1 is an L-shaped structure. The mixing barrel 2 is placed on the horizontal section of the supporting platform 1 through support legs 20 installed on its outer wall. A discharge port is opened at the bottom of the mixing barrel 2. The supporting platform 1 is installed with an existing fixing component (such as an existing fixing ring frame) for fixing the mixing barrel 2.

[0037] See also Figure 1 , Figure 2 and Figure 3The vertical section of the support platform 1 is connected to a lifting frame 3 through a general driving mechanism 8. The lower end of the lifting frame 3 is connected to a barrel cover 5 that matches the mixing barrel 2 through a fixed cylinder 4. The lifting frame 3 is also rotatably connected to a stirring shaft 6 that is concentric with the barrel cover 5 and has its lower end passing through the fixed cylinder 4 and the barrel cover 5. A stirring and pressing material conversion mechanism 7 is provided on the stirring shaft 6.

[0038] See also Figure 1 and Fig. 9 The total driving mechanism 8 is used to drive the stirring shaft 6 to rotate and drive the lifting frame 3 to move up and down. The total driving mechanism 8 includes a hydraulic cylinder 80 installed on the vertical section of the supporting platform 1 to drive the lifting frame 3 to move up and down. The lifting frame 3 is a hollow structure. A driving shaft is installed in the lifting frame 3. The stirring shaft 6 penetrates into the lifting frame 3 and is connected to the driving shaft through a transmission group (such as a gear group). A motor that drives the driving shaft to rotate is installed on the lifting frame 3 (the lifting frame 3 is not cut in the figure to show the driving shaft, the transmission group and the motor).

[0039] See also Figure 1 , Figure 2 and Figure 3 The stirring and pressing material conversion mechanism 7 includes three groups of stirring blades 71 which are connected to the stirring shaft 6 by sliding up and down through a folding matching group 70 and are arranged in sequence from top to bottom, and each group is composed of a plurality of stirring blades 71 which are evenly arranged along the circumference of the stirring shaft 6. The stirring blades 71 are in a fan-shaped structure. The three groups of stirring blades 71 are staggered along the circumference of the stirring shaft 6. When the folding matching group 70 is folded downward, the three groups of stirring blades 71 are staggered to form a complete disc structure. The folding matching group 70 is connected to the stirring shaft 6 through the plug-in group 72. The scraper rods 73 are evenly arranged around the mixing shaft 6, and a scraper blade 74 for cleaning the inner wall of the mixing barrel 2 is installed on the side of the scraper rod 73 away from the mixing shaft 6. The lower end of the scraper rod 73 is connected to the arc segment of the corresponding stirring blade 71 in the group of stirring blades 71 located on the lower side, and a sliding support group 75 for supporting the scraper rod 73 is installed on the group of stirring blades 71 located on the upper side; the three edges of the upper end surface of the stirring blade 71 are all in an arc structure to facilitate the plug-in assembly between the upper and lower stirring blades 71.

[0040] In the initial state, the three groups of stirring blades 71 and the folding and matching group 70 are inserted into the mixing barrel 2 in an unfolded state, and then the pathogen suspension and the carrier material are put into the mixing barrel 2 through the barrel cover 5 and the corresponding feeding port on the mixing barrel 2, and the main driving mechanism 8 is started to drive the stirring shaft 6 to rotate. During the rotation of the stirring shaft 6, the three groups of stirring blades 71 are driven to rotate through the folding and matching group 70. During the rotation, the stirring blade 71 mixes and stirs the pathogen suspension and the carrier material to ensure that the pathogens are evenly attached to the carrier. During the rotation of the stirring blade 71, the scraper rod 73 drives the scraper blade 74 to rotate synchronously with the stirring blade 71. The scraper blade 74 scrapes off the pathogen suspension and the carrier material adhered to the inner wall of the mixing barrel 2, so that the pathogen suspension and the carrier material can be fully mixed. At the same time, the scraper rod 73 also supports the stirring blade 71 and the folding and matching group 70 located on the upper side through the sliding support group 75 and the plug-in group 72, thereby improving the stability of the scraper rod 73 when rotating to drive the scraper blade 74 to scrape and clean.

[0041] See also Figure 1 and Figure 2 A folding driving mechanism 9 for driving the folding matching group 70 is installed on the top of the inner wall of the barrel cover 5.

[0042] When the pathogen suspension and the carrier material meet the standards after mixing and stirring (the mixed material should maintain appropriate humidity, neither too dry nor too wet, and can be squeezed into a ball by hand and can be dispersed after being released), the motor stops driving the stirring shaft 6 to rotate, and the hydraulic cylinder 80 drives the lifting frame 3 and the stirring and pressing material conversion mechanism 7 to move upward until the stirring shaft 6 is taken out from the bacteria-carrying material mixed with the pathogen suspension and the carrier material, and then the folding drive mechanism 9 drives the folding matching group 70 to drive the two groups of stirring blades 71 on the upper side to move downward until the three groups of stirring blades 71 are staggered to form a complete disc structure, so that the stirring and pressing material conversion mechanism 7 is transformed from a structure for stirring the pathogen suspension and the carrier material into a disc structure for pressing and pushing the bacteria-carrying material downward to discharge the material, thereby realizing the functions of mixing and stirring the pathogen suspension and the carrier material as well as the integrated function of feeding and discharging, greatly improving the convenience of mixing and stirring and discharging the pathogen suspension and the carrier material.

[0043] See also Figure 2 , Figure 3 , Figure 4 , Fig. 9 and Fig.10The folding matching group 70 includes a fixing ring 1 701, a fixing ring 2 702 and a fixing ring 3 703 which are sleeved on the stirring shaft 6 and arranged in sequence from top to bottom. A group of stirring blades 71 located on the upper side is fixedly connected to the lower end surface of the fixing ring 1 701, a group of stirring blades 71 located in the middle is fixedly connected to the fixing ring 2 702 through a connecting piece 704, a group of stirring blades 71 located on the lower side is fixedly connected to the outer ring surface of the fixing ring 3 703, and the lower end of the fixing ring 3 703 is connected to the fixing ring 3 703 through a connecting seat 705. The stirring shaft 6 is fixedly connected, and the upper end surface of the fixed ring three 703 is provided with a card groove 706 which is evenly arranged along its circumference and corresponds one to one with the connecting piece 704. The outer diameter of the fixed ring two 702 is smaller than the inner diameter of the fixed ring three 703. When folded, the fixed ring two 702 is inserted into the inner ring surface of the fixed ring three 703. The upper end of the fixed ring two 702 and the inner ring surface of the fixed ring one 701 are connected by sliding up and down through a clamping sleeve assembly, and when the stirring shaft 6 rotates, the fixed ring one 701 and the fixed ring two 702 are driven to rotate through the clamping sleeve assembly.

[0044] See also Figure 5 , Figure 6 , Figure 7 , Fig.10 and Fig.11 The ferrule assembly includes a connecting sleeve 710 which is mounted on the upper end face of a fixing ring 2 702 and is slidably sleeved on the outer side of a stirring shaft 6 by means of a spline fit, a limiting ring 711 is mounted on the top of the connecting sleeve 710, a fixing ring 1 701 is slidably sleeved on the outer wall of the connecting sleeve 710 by means of a spline fit, and a retaining ring 712 is fixedly sleeved on the stirring shaft 6 and is located above the connecting sleeve 710; the upper end of the fixing ring 1 701 is in a conical shape, so as to prevent the stirred pathogen suspension and carrier material from accumulating on the fixing ring 1 701, which affects the synchronous movement of the fixing ring 1 701 in the process of moving up and down and driving the connecting sleeve 710.

[0045] In the initial state, the top of the fixed ring 701 presses the limit ring 711 against the lower end surface of the baffle ring 712, thereby limiting the up and down movement of the connecting sleeve 710 and the fixed ring 2 702, so that the three groups of stirring blades 71 are evenly distributed in the mixing barrel 2 to mix and stir the pathogen suspension and the carrier material. The stirring shaft 6 drives the connecting sleeve 710 to rotate during the rotation process through the spline matching method, and the connecting sleeve 710 drives the fixed ring 1 701 to rotate through the spline matching method.

[0046] When it is necessary to discharge the materials, the folding driving mechanism 9 is started, and the folding driving mechanism 9 pushes the fixed ring 1 701 to move downward, and the fixed ring 2 702 moves downward synchronously under the action of its own gravity and the downward friction force of the fixed ring 1 701. When the fixed ring 2 702 is inserted into the fixed ring 3 703, the connecting piece 704 is inserted into the corresponding card slot 706, so that the lower end of the stirring blade 71 connected to the fixed ring 2 702 is flush with the bottom of the stirring blade 71 connected to the fixed ring 3 703, so as to facilitate the downward pressure and pushing of the materials, and then the fixed ring 1 701 continues to move downward until the bottom of the fixed ring 1 701 conflicts with the top of the stirring blade 71 connected to the fixed ring 2 702. At this time, the stirring blade 71 connected to the fixed ring 1 701 is inserted between the two adjacent stirring blades 71 connected to the fixed ring 2 702 and the fixed ring 3 703, thereby forming a complete disc, realizing the conversion from the stirring structure to the pressing structure, realizing the function of one machine with two uses, and being beneficial to improving the efficiency of the mixed preparation of the pathogen suspension and the carrier material.

[0047] See also Figure 2 and Figure 5 The outer ring surface of the fixed ring 701 is equipped with ribs 730 evenly arranged along its circumference. The ribs 730 are inclined and connected one by one with the upper end surfaces of the corresponding stirring blades 71 connected to the lower end of the fixed ring 701, thereby improving the supporting force of the stirring blades 71 connected to the lower end of the fixed ring 701, avoiding the lack of connection between the fixed ring 701 and the stirring blades 71 connected to the lower end, resulting in insufficient supporting force of the stirring blades 71 connected to the fixed ring 701.

[0048] See also Figure 2 , Figure 5 and Fig.10 Except for the stirring blade 71 connected to the fixing ring 701, the upper end surfaces of the other stirring blades 71 are all equipped with auxiliary stirring rods 731, and the auxiliary stirring rods 731 are inclined. The lower end surface of the fixing ring 701 is provided with sliding slots 732 arranged along its circumference and corresponding to the auxiliary stirring rods 731 one by one.

[0049] When the three groups of stirring blades 71 from top to bottom are dispersed to stir the pathogen suspension and the carrier material, the auxiliary stirring rod 731 rotates synchronously with the stirring blades 71 connected thereto, and assists in stirring the pathogen suspension and the carrier material, thereby improving the mixing effect of the pathogen suspension and the carrier material; when the three groups of stirring blades 71 are folded, the auxiliary stirring rod 731 is inserted into the sliding slot 732 away from the end of the stirring blade 71 connected thereto. At this time, the stirring blades 71, the auxiliary stirring rod 731 and the fixing ring 701 form a stable triangular structure, thereby improving the supporting force of the stirring blades 71 when pushing down the pathogen suspension and the carrier material mixture for discharging.

[0050] See also Figure 2 The sliding support group 75 includes an arc-shaped filling bar 750 that slides up and down and is connected between two adjacent scraper rods 73. The arc-shaped filling bar 750 is fixedly connected to a group of arc-shaped segments of a stirring blade 71 located on the upper side, so that the stirring blade 71 and the scraper rod 73 support each other, and when the three groups of stirring blades 71 are folded, the arc-shaped filling bar 750 moves downward along the scraper rod 73 with the stirring blade 71 connected thereto until the arc-shaped filling bar 750 is stuck between the stirring blade 71 and the inner wall of the mixing barrel 2. The arc-shaped filling bar 750 fills the gap between the two adjacent scraper rods 73 and the stirring blade 71 and the inner wall of the mixing barrel 2 to prevent the disc formed by the multiple stirring blades 71 from overflowing upward from the gap when the pathogen suspension and the carrier material mixture are pressed down and pushed, thereby affecting the effect of pressing down and discharging.

[0051] See also Figure 2 , Figure 5 and Fig.10 The plug-in group 72 includes an oblique connecting rod 720 installed on the upper end of the scraper rod 73, and the end of the oblique connecting rod 720 away from the scraper rod 73 is plugged into the outer ring surface of the fixing ring 701, thereby improving the supporting force of the scraper rod 73, so that the scraper rod 73 can clean the inner wall of the mixing barrel 2.

[0052] See also Figure 1 , Figure 2 , Figure 8 and Fig.10 The folding driving mechanism 9 includes a rotating ring 91 rotatably connected to the outer ring surface of the upper end of the fixed ring 701. Two push rods 90 are installed on the top of the rotating ring 91. The rotating ring 91 is located above the oblique connecting rod 720, so as to prevent the push rod 90 from affecting the oblique connecting rod 720 to rotate with the fixed ring 701. After the two push rods 90 slide through the barrel cover 5, they are jointly connected to the telescopic end of the external hydraulic cylinder 2. The external hydraulic cylinder 2 pushes the fixed ring 701 downward through the push rod 90.

[0053] Working principle: In the initial state, the three groups of stirring blades 71 and the folding matching group 70 are inserted into the mixing barrel 2 in an unfolded state. During the rotation of the stirring shaft 6, the three groups of stirring blades 71 are driven to rotate through the folding matching group 70. During the rotation, the stirring blades 71 mix and stir the pathogen suspension and the carrier material to ensure that the pathogens are evenly attached to the carrier; during the rotation of the stirring blades 71, the scraper rod 73 drives the scraper 74 to rotate synchronously with the stirring blades 71, and the scraper 74 scrapes off the pathogen suspension and the carrier material adhered to the inner wall of the mixing barrel 2, so that the pathogen suspension and the carrier material can be fully mixed.

[0054] When the mixture of pathogen suspension and carrier material meets the standard, the main driving mechanism 8 drives the stirring shaft 6 to take out the carrier material mixed with pathogen suspension and carrier material, and then the folding driving mechanism 9 drives the folding matching group 70 to drive the two groups of stirring blades 71 on the upper side to move downward, until the three groups of stirring blades 71 are staggered to form a complete disc structure, so that the stirring and pressing material conversion mechanism 7 is transformed from a structure for stirring the pathogen suspension and the carrier material to a disc structure for pressing and pushing the mixture to discharge the material, thereby realizing the functions of mixing and stirring the pathogen suspension and the carrier material as well as the integrated function of material discharge and discharge, which greatly improves the convenience of mixing and discharging the pathogen suspension and the carrier material.

[0055] Finally, the hydraulic cylinder 80 drives the lifting frame 3, the stirring shaft 6 and the disc composed of multiple stirring blades 71 to move downward to squeeze the bacteria-carrying material formed by the mixture of the pathogen suspension and the carrier material downward, and the bacteria-carrying material is discharged from the discharge port.
