Description

Technical Field

[0001] The present invention relates to the technical field of fermentation tanks, and particularly to a fermentation tank for feed processing. Background Art

[0002] The utilization of feed has always been an important issue in the livestock industry. Although traditional animal feed can meet the animals' food requirements, the feed utilization rate is low. Most of the nutrients in the feed cannot be absorbed and utilized by animals, which affects animal growth, wastes resources. Fermented feed uses microorganisms and compound enzymes as biological feed fermentation agent strains to convert feed raw materials into microbial cell protein, bioactive small peptide amino acids, microbial active probiotics, and compound enzyme preparations. This product can not only make up for the amino acids that are easily lacking in conventional feed, but also quickly convert the nutritional components of other rough feed raw materials, achieving the effect of enhancing digestion, absorption, and utilization.

[0003] Since most of the current fermentation tanks are welded, a stirring mechanism is arranged inside to mix the fermentation raw materials. Stirring can accelerate the metabolism and growth of microorganisms, thereby promoting the reaction rate, improving the fermentation efficiency and output. However, due to the relatively special structure of the stirring rod, it is very troublesome to clean. The dirt and residues in the tank provide an environment for the growth of microorganisms, and it is easily contaminated by miscellaneous bacteria, affecting the fermentation quality. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a fermentation tank for feed processing.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fermentation tank for feed processing, including a tank body. The top of the tank body is equipped with a tank cover. A motor frame is fixed on the top of the tank cover, and a driving motor is fixed on the motor frame. The bottom of the inner wall of the tank body is rotatably provided with a first lead screw, and a stirring member is installed on the first lead screw. An adjusting member for connecting and disconnecting the output shaft of the driving motor and the first lead screw is installed on the tank cover. Two symmetric second fixing ears are fixed on the top of the outer wall of the tank body, and a height adjusting mechanism for moving the tank cover is installed on the first fixing ear;

[0007] The adjusting member includes a first synchronous wheel rotatably arranged on the top of the tank cover. A hole is opened in the center of the first synchronous wheel. The top of the first lead screw is fixed with a mounting head, and the mounting head passes through the tank cover and the hole on the first synchronous wheel. The mounting head is telescopically installed with a square clamping block, and the square clamping block is detachably connected to the output shaft of the driving motor. A fixing workpiece is fixed on the outer wall of the square clamping block, a top block is fixed at the bottom of the fixing workpiece, and a notch is opened on the top of the first synchronous wheel;

[0008] The height adjustment mechanism includes a second screw rod arranged on the first fixing ear, and the thread directions of the two second screw rods are the same. The second screw rod is equipped with a second screw rod nut, and the first synchronous wheel is connected to the two second screw rod nuts through a synchronous member.

[0009] As a further solution of the present invention, a square slot is provided on the top of the mounting head, and a first spring is fixed to the bottom of the inner wall of the square slot, and the top of the first spring is fixed to the bottom of the square block. When the first spring is not stretched, the square block is located at the bottom of the square slot, and the top block is located in the slot. The square block is pulled out to fix the output shaft of the drive motor and the square block by bolts and nuts, and the top block moves up and out of the slot, thereby realizing connection and disassembly with the drive motor. When the drive motor is connected to the square block, the drive motor can drive the stirring element to achieve rotation and stirring to mix the feed fermentation process. When disassembled, the top block is located in the slot, and the lever can be held to achieve rotation of the first synchronous wheel, and the square block is located in the square slot.

[0010] As a further solution of the present invention, a socket is provided on the top of the square block, a screw hole passing through the socket is provided on the outer wall of the square block, the output shaft of the drive motor is inserted into the socket and fixed by bolts passing through the screw hole and the hole of the output shaft of the drive motor.

[0011] As a further solution of the present invention, a plurality of shifting rods are fixed at equal intervals on the top of the first synchronous wheel.

[0012] As a further solution of the present invention, the synchronous part includes a second synchronous wheel fixed at the bottom of the second screw nut, and the second synchronous wheel is provided with a hole for the second screw to pass through, and the two second synchronous wheels are respectively connected to the first synchronous wheel through the first synchronous belt and the second synchronous belt.

[0013] As a further solution of the present invention, a second fixing ear is fixed on the outer wall of the tank cover at a position corresponding to the first fixing ear, and a hole is provided on the second fixing ear for the second screw to pass through. A fixing frame is fixed to the top of the first fixing ear, and the top of the second screw is fixedly connected to the top inner wall of the fixing frame. Two symmetrical fixing arms are fixed to the top of the tank cover, and a ring is fixed on the end face of the fixing arm. A limiting groove ring is provided on the outer wall of the second screw nut, and the ring is adapted to the limiting groove ring. Under the action of the fixing arm and the ring, since the ring is sleeved in the limiting groove ring, it does not affect the rotation of the second screw nut and drives the tank cover to move upward.

[0014] As a further solution of the present invention, the stirring member includes three first lead screw nuts adapted to the first lead screw. A plurality of stirring blades are fixedly arranged on the outer wall of the first lead screw nut at equal intervals. Two second connecting rods are rotatably arranged at the bottom of the two first lead screw nuts located in the upper part. Two first connecting rods are rotatably arranged at the top of the two first lead screw nuts located in the lower part. The first connecting rod is rotatably connected to the corresponding second connecting rod. The upper part of the first lead screw is not provided with a thread groove. When the first lead screw nut on the first lead screw moves upward, first, the first lead screw nut located at the topmost part disengages from the threaded position of the first lead screw, and then disengages in sequence. Under the action of the first connecting rod and the second connecting rod, the first lead screw nut located at the bottommost part will push the upper first lead screw nut upward, and finally approach and fit with each other. The entire stirring member moves upward to the uppermost part of the first lead screw. And the above design ensures that the first lead screw nut at the bottommost part will never disengage from the thread of the first lead screw, so that when the stirring member moves downward, the first lead screw nut at the bottommost part plays a role of pulling down to expand and realize the stirring function.

[0015] As a further solution of the present invention, a U-shaped sampling tube is arranged inside the tank body. Both ends of the U-shaped sampling tube pass through the outer wall of the tank body, and the tank body is provided with a hole for the U-shaped sampling tube to pass through. A feed pipe orifice is fixedly communicated with the bottom of the outer wall of the U-shaped sampling tube. A manual valve is fixed to the end face of the U-shaped sampling tube passing through the outer wall of the tank body. A bottom sleeve is sleeved on the bottom of the second synchronous pulley close to the U-shaped sampling tube. A reinforcing rod is fixed to the bottom of the sleeve. The sleeve is sleeved on the outer wall of the corresponding second lead screw. The second fixed ear and the first fixed ear are provided with holes for the sleeve to pass through. The part of the U-shaped sampling tube passing through the outer wall of the tank body is evenly provided with tooth grooves. A gear meshing with the tooth grooves is fixedly sleeved on the outer wall of the reinforcing rod. A clamping plate is fixed to the part of the U-shaped sampling tube passing through the outer wall of the tank body. A second spring is fixed to the clamping plate. The other end of the second spring is fixed to a connecting block. The two connecting blocks are respectively fixed to the outer wall of the first fixed ear and the outer wall of the tank body. The connecting block, the second spring and the clamping plate are provided. When the gear rotates and just disengages from the tooth grooves, at this time, the second spring is in a compressed state and the U-shaped sampling tube will no longer move into the tank body. When the tank cover moves downward, the gear rotates in the reverse direction, the second spring expands, so that the gear and the tooth grooves can quickly mesh and will not be disengaged.

[0016] As a further solution of the present invention, the discharge port of the tank body is arranged at a position deviating from the center at the bottom of the tank body.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. A tank body, a tank cover, a driving motor, a height adjustment mechanism, an adjusting member, a first screw rod, a stirring member and a reinforcing rod are provided. When the driving motor is connected to the square block, the stirring member can be driven by the driving motor to rotate and stir, so as to mix the feed fermentation process. When disassembled, the top block is located in the notch, and the lever can be held to realize the rotation of the first synchronous wheel; when the first synchronous wheel is rotated, under the action of the first synchronous belt and the second synchronous belt, the two second synchronous wheels are rotated in the same direction, and then the two second screw nuts are moved up on the two communicating second screw rods. Under the action of the fixed arm and the collar, since the collar is sleeved in the limiting groove ring, the rotation of the second screw nut is not affected, and the tank cover is driven to move up, and at the same time, the stirring member located inside the tank body is driven to move up, so that the tank cover is opened, the stirring member is moved up, and the stirring member and the inside of the tank body can be rinsed.

[0019] 2. A stirring piece, a U-shaped sampling tube, a reinforcing rod, a gear and a tooth groove opened on the U-shaped sampling tube are provided. When the second synchronous wheel rotates, the rotation of the shell can be realized at the same time, and then the shell drives the reinforcing rod and the gear to rotate, and the U-shaped sampling tube is pushed to move into the tank body through the gear, so that the U-shaped sampling tube blocks the stirring blade, forcing the stirring blade to be blocked and not to rotate, and then when the first screw rod rotates, the first screw rod nut on the first screw rod moves up. The above design ensures that the first screw rod nut at the bottom will never be separated from the thread of the first screw rod, so that when the stirring piece moves down, the first screw rod nut at the bottom plays a pulling-down role and expands to realize the stirring effect. Combined with the upward movement of the tank cover, the upward movement and mutual retraction of the stirring piece, the stirring piece is exposed at the top of the tank body, which is convenient for rinsing and keeping the stirring piece clean.

[0039] In this embodiment, the stirring member 6 includes three first lead screw nuts 601 adapted to the first lead screw 5. A number of stirring blades 602 are equidistantly fixed to the outer wall of the first lead screw nut 601. Two second connecting rods 604 are rotatably arranged at the bottom of the two first lead screw nuts 601 located in the upper part, and two first connecting rods 603 are rotatably arranged at the top of the two first lead screw nuts 601 located in the lower part.

A feed pipe orifice 701 is fixedly communicated with the bottom of the outer wall of the U-shaped sampling pipe 7. A manual valve 702 is fixed to the end face of the U-shaped sampling pipe 7 passing through the outer wall of the tank body 1. A bottom housing 38 of the second synchronous pulley 26 is sleeved near the U-shaped sampling pipe 7. A reinforcing rod 30 is fixed to the bottom of the housing 38. The housing 38 is sleeved on the outer wall of the corresponding second lead screw 23. The second fixed ear 22 and the first fixed ear 21 are provided with holes for the housing 38 to pass through. Tooth grooves 34 are evenly formed on the part of the U-shaped sampling pipe 7 passing through the outer wall of the tank body 1.

The connecting block 35, the second spring 36 and the clamping plate 37 are provided. When the gear 31 rotates and just disengages from the tooth grooves 34, the second spring 36 is in a compressed state at this time, and the U-shaped sampling pipe 7 will no longer move into the tank body 1. When the tank cover 2 moves downward, the gear 31 rotates in the reverse direction, and the second spring 36 expands, so that the gear 31 and the tooth grooves 34 can be quickly meshed and will not be disengaged.

[0041] In this embodiment, the discharge port of the tank body 1 is arranged at a position deviating from the center at the bottom of the tank body 1.

[0042] When in use: a tank body 1, a tank cover 2, a driving motor 4, a height adjustment mechanism 8, an adjusting component 9, a first screw rod 5, a stirring piece 6 and a reinforcing rod 30 are provided, wherein the adjusting component 9 includes a first synchronous wheel 16, a notch 17, a mounting head 10, a square card slot 11, a first spring 12, a square card block 13, a top block 20 and a fixed workpiece 19, etc. When the first spring 12 is not stretched, the square card block 13 is located at the bottom of the square card slot 11, and the top block 20 is located in the notch 17. The square card block 13 is pulled out to realize that the output shaft of the driving motor 4 is fixed to the square card block 13 by bolts and nuts, and the top block 20 moves up and out of the notch 17, thereby realizing connection and disassembly with the driving motor 4. When the driving motor 4 is connected to the square card block 13, the stirring piece 6 can be driven by the driving motor 4 to realize rotation and stirring, so as to mix the feed fermentation process. When the first synchronous wheel 16 is closed, the top block 20 is located in the notch 17, and the lever 18 can be held to realize the rotation of the first synchronous wheel 16; the height adjustment mechanism 8 includes a second screw rod 23, a second screw rod nut 25, a second synchronous wheel 26, a first synchronous belt 28 and a second synchronous belt 29, etc. When the first synchronous wheel 16 is rotated, under the action of the first synchronous belt 28 and the second synchronous belt 29, the two second synchronous wheels 26 are rotated in the same direction, thereby realizing the upward movement of the two second screw rod nuts 25 on the two communicating second screw rods 23. Under the action of the fixed arm 32 and the collar 33, since the collar 33 is sleeved in the limiting groove ring 27, the rotation of the second screw rod nut 25 is not affected, and the tank cover 2 is driven to move upward, and at the same time, the stirring member 6 located inside the tank body 1 is driven to move upward, so that the tank cover 2 is opened and the stirring member 6 is moved upward, and the stirring member 6 and the inside of the tank body 1 can be rinsed;

[0043] Further, the provided stirring member 6 includes a first lead screw nut 601, stirring blades 602, a first connecting rod 603 and a second connecting rod 604, and a U-shaped sampling tube 7, a reinforcing rod 30, a gear 31 and a tooth groove 34 opened on the U-shaped sampling tube 7 are provided. A housing 38 is fixed to the bottom of the second synchronous pulley 26. The housing 38 is fixed with the reinforcing rod 30. The reinforcing rod 30 is fixed with the gear 31 meshing with the tooth groove 34. When the second synchronous pulley 26 rotates, the rotation of the housing 38 can be realized simultaneously. Further, the housing 38 drives the reinforcing rod 30 and the gear 31 to rotate. The U-shaped sampling tube 7 is pushed into the interior of the tank body 1 by the gear 31, so that the U-shaped sampling tube 7 blocks the stirring blades 602, forcing the stirring blades 602 not to rotate when blocked. Further, when the first lead screw 5 rotates, the first lead screw nut 601 on the first lead screw 5 moves upward. First, the first lead screw nut 601 located at the uppermost part disengages from the thread position of the first lead screw 5, and then disengages in sequence. Under the action of the first connecting rod 603 and the second connecting rod 604, the first lead screw nut 601 located at the bottommost part will push the upper first lead screw nut 601 upward, and finally move closer to each other and fit together. The entire stirring member 6 moves upward to the uppermost part of the first lead screw 5. And the above design ensures that the first lead screw nut 601 at the bottommost part will never disengage from the thread of the first lead screw 5, so that when the stirring member 6 moves downward, the first lead screw nut 601 at the bottommost part plays a role of pulling down to expand and realize the stirring function. Combining the upward movement of the tank cover 2, the upward movement and mutual folding of the stirring member 6 facilitates the exposure of the stirring member 6 at the top of the tank body 1, which is convenient for flushing and keeping the stirring member 6 clean.
