When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 11 As shown, the present invention is a device for producing biological feed using corn meal, comprising: a stirring tank 1, a circular feeding opening is opened on the top of the stirring tank 1, a discharge pipe for discharging materials is installed at the bottom of the stirring tank 1, and a control valve is installed on the discharge pipe; a stirring mechanism 3 for stirring raw materials such as corn meal.

[0024] Corn meal is mixed with other fermentation raw materials (such as corn bran, sugar residue, etc.) in a certain proportion to prepare a fermentation medium. The prepared fermentation liquid is then inoculated into the fermentation medium and mixed evenly. The bacteria can produce beneficial metabolites during the fermentation process, thereby improving the nutritional value of the feed.

[0025] The stirring mechanism 3 includes: a rotating shaft 31 rotatably mounted on the stirring tank 1; a power source 1 32 driving the rotating shaft 31 to rotate, and the power source 1 32 is installed on the stirring tank 1 through a mounting frame; a circular tube 33 fixedly mounted on the end of the rotating shaft 31; a stirring plate 34 rotatably mounted on the circular tube 33; a driven bevel gear 36 coaxially connected to the stirring plate 34; a driving bevel gear 35 meshingly connected to the driven bevel gear 36; a power source 2 37 driving the driving bevel gear 35 to rotate, and the power source 2 37 is fixedly mounted in the circular tube 33; and a scraper 38 coaxially connected to the driving bevel gear 35.

[0026] When stirring raw materials such as corn meal, the power source 32 is started to drive the rotating shaft 31 to rotate, the rotating shaft 31 drives the circular tube 33 to rotate, and the circular tube 33 drives the stirring plate 34 to rotate, thereby achieving stirring of raw materials such as corn meal.

[0027] At the same time, by starting the second power source 37 , the active bevel gear 35 is driven to rotate, and the active bevel gear 35 drives the driven bevel gear 36 to rotate, thereby driving the stirring plate 34 to rotate, thereby achieving angle adjustment of the stirring plate 34 .

[0028] When the stirring plate 34 is in the first mode, that is, the stirring plate 34 is adjusted 45 degrees clockwise, the stirring plate 34 is relatively inclined with respect to the rotating shaft 31. At this time, the raw materials can be continuously turned upward and stirred by the clockwise rotation of a plurality of stirring plates 34, so that the raw materials are evenly mixed; When the stirring plate 34 is in the second mode, that is, the stirring plate 34 is adjusted 45 degrees counterclockwise to restore the stirring plate 34 to its original position, the angle of the stirring plate 34 is 0, the stirring plate 34 is parallel to the circular tube 33, and the raw materials move in a circular motion under the push of the stirring plate 34. At this time, the turned raw materials can be fully stirred until the mixing is completed; When the stirring plate 34 is in the third mode, that is, the stirring plate 34 is adjusted 45 degrees counterclockwise, the stirring plate 34 and the rotating shaft 31 are relatively inclined. At this time, the mixed raw materials can be continuously turned downward by the clockwise rotation of a plurality of stirring plates 34, so that the raw materials are gathered at the discharge pipe, which is convenient for discharging the mixed raw materials. By adjusting the three angle modes of the stirring plate 34, the raw materials can be stirred in various states, realizing the turning, stirring and discharging of the raw materials, improving the uniformity of raw material mixing and the mixing efficiency. Compared with the existing stirring structure, this structure is more stable, efficient, simple and easy to operate.

[0029] In addition, when the scraper 38 rotates, the raw materials at the bottom of the mixing tank 1 can be stirred, thereby achieving comprehensive stirring of the raw materials and further improving the uniformity of mixing.

[0030] When the discharging is completed, the power source 2 37 is started to drive the active bevel gear 35 to rotate continuously, and the active bevel gear 35 drives the driven bevel gear 36 to rotate continuously, so that the stirring plate 34 and the scraper 38 are rotated continuously. Due to the effect of centrifugal force, the raw materials attached to the surface of the stirring plate 34 and the scraper 38 can be thrown off, thereby realizing the self-cleaning of the stirring plate 34 and the scraper 38.

[0031] It is to be added here that the power source 1 32 is preferably a motor; the power source 2 37 is preferably a motor.

[0032] The invention also includes: a premixing mechanism 2 for pretreating corn meal and other granular raw materials; the premixing mechanism 2 includes: an inner box 21 fixedly installed in the mixing tank 1, the inner box 21 is divided into a feed chamber 4 and a premixing chamber 5; a piston 1 22 and a piston 23 arranged in the inner box 21; a crushing knife 24 fixedly installed on the piston 23, a plurality of crushing knives 24 are arranged and evenly distributed along the circumference of the piston 23; an adjusting component 25 for adjusting the position of the piston 1 22 and the piston 23; an auxiliary stirring device 25 for auxiliary stirring of corn meal and other granular raw materials; a plurality of auxiliary stirring devices ... Auxiliary component 26; the adjustment component 25 includes: a movable tube 253 slidably installed on the rotating shaft 31, a piston 22 rotatably installed on the movable tube 253, and a piston 23 fixedly sleeved on the movable tube 253; a limiting groove opened in the movable tube 253; a limiting strip 254 slidably installed in the limiting groove; a movable plate 252 rotatably installed on the movable tube 253; a power source 3 251 that drives the movable plate 252 to move, and the power source 3 251 is fixedly installed in the mounting frame; the limiting strip 254 is fixedly connected to the rotating shaft 31.

[0033] In the prior art, during the premixing stage, corn meal and other granular raw materials are premixed with fermentation liquid, which easily leads to agglomeration of the raw materials, making it difficult for the raw materials to be discharged from the premixing chamber 5. In the present invention, during premixing, only corn meal and other granular raw materials are premixed, thereby avoiding agglomeration of the raw materials and facilitating the discharge of the mixed raw materials from the premixing chamber 5.

[0034] Corn meal and other granular raw materials are placed into the feed chamber 4 through the circular feed opening. In the initial state, the piston 22 seals the connecting opening between the feed chamber 4 and the premixing chamber 5, so that the raw materials in the feed chamber 4 cannot enter the premixing chamber 5.

[0035] At this time, the power source three 251 is started to drive the movable plate 252 to move downward, and the movable plate 252 drives the movable tube 253 to move downward, thereby driving the piston one 22 and the piston two 23 to move downward. At this time, the piston one 22 has no sealing effect on the connecting opening, and the raw material enters the premixing chamber 5 from the feeding chamber 4, and causes the piston two 23 to move downward to seal the discharge opening at the bottom of the premixing chamber 5.

[0036] When the premixing is completed, the power source 3 251 drives the movable plate 252 to return upward, thereby driving the piston 1 22 and the piston 2 23 to return to their original positions, and the premixed raw materials are discharged from the premixing chamber 5 .

[0037] During premixing, that is, when the raw materials enter the premixing chamber 5, the power source 1 32 is started to drive the rotating shaft 31 to rotate, the rotating shaft 31 drives the limit bar 254 to rotate, the limit bar 254 drives the movable tube 253 to rotate, and the movable tube 253 drives the piston 23 to rotate, thereby driving the crushing knife 24 to rotate. Through the rotation of the crushing knife 24, the raw materials can be stirred while having a certain crushing function, so that the particle size of the raw materials is smaller, which is convenient for better premixing of the raw materials, thereby alleviating the pressure of the stirring mechanism 3 when stirring multiple raw materials.

[0038] It is to be added here that the power source three 251 is preferably a cylinder.

[0039] Although the pulverizing blade 24 can premix the raw materials, the raw materials cannot be fully premixed, resulting in limited premixing effect.

[0040] The auxiliary component 26 includes: an air collecting chamber 261 opened on the side wall of the inner box 21; a nozzle 262 connected to the air collecting chamber 261; an air pump 263 for supplying air to the nozzle 262; a switching unit 264 for switching the gas flow direction; the switching unit 264 includes: an air collecting pipe 2641 fixedly installed on the mounting frame; a piston three 2642 slidably installed in the air collecting pipe 2641; a movable rod 2643 fixedly connected to the piston three 2642, and the movable rod 2643 is fixedly connected to the movable plate 252; an air inlet pipe 2644 connecting the air pump 263 and the air collecting pipe 2641; an air outlet pipe one 2645 connecting the air collecting pipe 2641 and the air collecting chamber 261.

[0041] Piston three 2642 separates the air collecting pipe 2641 into two independent spaces. The outlet end of the air inlet pipe 2644 is located near the middle of the air collecting pipe 2641, and the air inlet end of the air outlet pipe one 2645 is located near the top of the air collecting pipe 2641. Since in the initial state, piston 1 22 seals the connecting opening between the feed chamber 4 and the premixing chamber 5, at this time, piston 3 2642 separates the outlet end of the inlet pipe 2644 from the inlet end of the outlet pipe 1 2645, so that the inlet pipe 2644 and the outlet pipe 1 2645 cannot be connected. When piston 1 22 moves downward, the raw material enters the premixing chamber 5. At the same time, the movable plate 252 moves downward, which can drive the movable rod 2643 to move downward. The movable rod 2643 drives piston 3 2642 to move downward, so that piston 3 2642 moves to below the outlet end of the inlet pipe 2644, thereby connecting the outlet end of the inlet pipe 2644 with the inlet end of the outlet pipe 1 2645.

[0042] While the crushing knife 24 is premixing the raw materials, the air pump 263 is started, and the high-pressure gas passes through the air inlet pipe 2644, the air collecting pipe 2641, and the air outlet pipe 2645 in sequence, enters the air collecting chamber 261, and is sprayed out through a plurality of spray heads 262.

[0043] The high-pressure gas ejected from the jet head 262 can, on the one hand, blow up the raw materials so that the raw materials float toward the crushing knife 24, thereby improving the crushing effect of the crushing knife 24 on the raw materials. On the other hand, it can improve the dispersion of the raw materials and improve the premixing effect of the raw materials.

[0044] The stirring mechanism 3 also includes: a liquid supply component 39 for conveying fermented bacterial liquid into the stirring tank 1; the liquid supply component 39 includes: a liquid storage tank 391 fixedly mounted on the stirring tank 1; an annular tube 392 fixedly mounted on the inner box 21; a liquid spray head 393 hingedly mounted on the annular tube 392, the liquid spray head 393 and the annular tube 392 are connected through a liquid guide tube; an air outlet pipe 295 connecting the air collecting pipe 2641 and the annular tube 392, the air inlet end of the air outlet pipe 295 is located near the bottom end of the air collecting pipe 2641; the fermented bacterial liquid in the liquid storage tank 391 is conveyed to the conveying unit 394 in the annular tube 392; the liquid spray head 393 is driven to swing The swing unit 396 for spraying; the conveying unit 394 includes: a collecting pipe 3941 fixedly installed on the liquid storage tank 391; a connecting pipe 3943 movably installed in the collecting pipe 3941, the connecting pipe 3943 is fixedly connected to the movable plate 252; a piston four 3942 fixedly sleeved on the connecting pipe 3943; a liquid inlet pipe 3947 connecting the collecting pipe 3941 and the liquid storage tank 391, the liquid inlet pipe 3947 is installed with a first one-way valve; a liquid outlet pipe 3948 connecting the collecting pipe 3941 and the annular pipe 392, the liquid outlet pipe 3948 is installed with a second one-way valve; the piston four 3942 is slidably installed in the collecting pipe 3941.

[0045] Since the premixing chamber 5 only premixes the granular raw materials such as corn meal, the premixed raw materials enter the stirring tank 1 through the discharge opening and are stirred by the stirring mechanism 3. While the granular raw materials such as corn meal are being stirred, the fermentation liquid is sprayed into the granular raw materials such as corn meal to achieve mixing of the granular raw materials and the fermentation liquid.

[0046] When the movable plate 252 moves downward, the linkage tube 3943 can be driven to move downward, and the linkage tube 3943 can drive the piston 3942 to move downward, so as to squeeze the fermentation liquid in the liquid collecting pipe 3941. At this time, the first one-way valve is closed, and the second one-way valve is opened, and the fermentation liquid enters the annular tube 392 through the liquid outlet pipe 3948, so as to prepare for subsequent spraying.

[0047] When the raw materials in the premixing chamber 5 are premixed, the movable plate 252 returns to its original position, thereby driving the piston 22 and the piston 3942 to return to their original position. When the piston 3942 returns to its original position, the first one-way valve opens, the second one-way valve closes, and the fermentation liquid enters the liquid collecting pipe 3941 from the liquid storage tank 391 through the liquid inlet pipe 3947.

[0048] At the same time, the movable plate 252 drives the piston three 2642 to reset upward. At this time, the piston three 2642 separates the outlet end of the air inlet pipe 2644 from the air inlet end of the air outlet pipe one 2645, so that the air inlet pipe 2644 is connected with the air outlet pipe two 395.

[0049] After the piston 22 is reset upward, the raw materials in the premixing chamber 5 are discharged. At the same time, the pump body is started, and the high-pressure gas passes through the air inlet pipe 2644, the air inlet pipe 2644, and the air outlet pipe 395 in sequence and enters the annular tube 392, thereby increasing the air pressure in the annular tube 392. The fermentation liquid in the annular tube 392 is subjected to the pressure of the air pressure and enters the spray head 393 through the liquid guide pipe and is sprayed out, thereby achieving the discharge of the raw materials in the premixing chamber 5 and spraying the fermentation liquid into the raw materials at the same time, thereby achieving preliminary mixing of the granular raw materials and the fermentation liquid.

[0050] It should be added here that since the distances moved up and down by piston 4 3942 are the same, quantitative spraying of the fermentation liquid is achieved.

[0051] The conveying unit 394 also includes: a rotating rod 3945 rotatably installed on the liquid collecting pipe 3941 and the liquid storage tank 391; a guide groove 3946 opened on the rotating rod 3945; a rolling member 3944 rotatably installed in the linkage tube 3943; a stirring blade 3949 fixedly installed on the rotating rod 3945; the guide groove 3946 is spiral, and the rolling member 3944 is rollingly installed in the guide groove 3946.

[0052] When the linkage tube 3943 moves up and down, it can drive the rolling element 3944 to move along the path of the guide groove 3946. Since the guide groove 3946 is spiral, the rotating rod 3945 rotates, and the rotating rod 3945 drives the stirring blade 3949 to stir the fermentation liquid in the liquid storage tank 391, so that the concentration of the fermentation liquid in the liquid storage tank 391 remains uniform.

[0053] It is to be added here that the rolling element 3944 is preferably a bull's eye ball.

[0054] The swing unit 396 includes: a guide plate 3961 fixedly mounted on the rotating shaft 31; a linkage spring 3962 for driving the liquid spray head 393 to return to its original position; one end of the linkage spring 3962 is fixedly connected to the annular tube 392, and the other end of the linkage spring 3962 is fixedly connected to the liquid spray head 393.

[0055] The guide plate 3961 is in a petal shape, and the top of the guide plate 3961 is in an arc shape.

[0056] When the granular raw material and the fermentation liquid are fed at the same time, the power source 32 is started to drive the stirring plate 34 to mix and stir the granular raw material and the fermentation liquid. At the same time, the rotating shaft 31 drives the guide plate 3961 to rotate. When the guide plate 3961 rotates, it can drive the spray head 393 to move along its petal-shaped edge, and cooperate with the elastic force of the linkage spring 3962 to make the multiple spray heads 393 synchronously retract inward or expand outward, that is, the swing of the spray head 393 is realized, thereby expanding the spraying range of the fermentation liquid, which is beneficial to the mixing of the fermentation liquid and the granular raw material.

[0057] In addition, the premixed granular raw materials fall onto the guide plate 3961 through the discharge opening. Since the top of the guide plate 3961 is arranged in an arc shape and the guide plate 3961 rotates, the granular raw materials can be dispersed in the stirring tube, thereby avoiding the accumulation of raw materials and further improving the mixing efficiency of the raw materials.

[0058] In the present invention, by starting power source three 251, the movable plate 252 can be driven to move up and down. When the movable plate 252 moves downward, the piston one 22, the piston two 23, the piston three 2642, and the piston four 3942 can be synchronously driven to move downward; the piston one 22 moves downward to release the closure of the connecting opening, so that the granular raw material enters the premixing chamber 5; the piston two 23 moves downward to close the discharge opening of the premixing chamber 5, thereby realizing the premixing of the raw materials; the piston three 2642 moves downward to connect the outlet end of the air inlet pipe 2644 with the inlet end of the air outlet pipe one 2645, so that the gas enters the gas collecting chamber 261 and is sprayed out through the nozzle 262, thereby realizing the gas stirring of the raw materials; the piston four 3942 moves downward to transport the fermentation bacteria liquid in the liquid collecting pipe 3941 to the annular pipe 392, so as to prepare for subsequent spraying.

[0059] When the movable plate 252 is reset upward, it can synchronously drive piston 1 22, piston 2 23, piston 3 2642, and piston 4 3942 to move upward; piston 1 22 is reset upward to seal the connecting opening to prevent the raw materials in the feed chamber 4 from entering the premixing chamber 5; piston 2 23 is reset upward to release the seal on the discharge opening to discharge the premixed granular raw materials; piston 3 2642 is reset upward to connect the air inlet pipe 2644 with the air outlet pipe 2 395, so that the fermented bacterial liquid in the annular tube 392 is subjected to the air pressure and enters the liquid spray head 393 through the liquid guide tube for spraying; piston 4 3942 is reset upward to absorb the fermented bacterial liquid in the liquid storage tank 391 into the liquid collecting pipe 3941 to prepare for subsequent transportation.
