Description

Technical Field

[0001] The invention relates to the field of feed mixing equipment, in particular to a feed mixing device with automatic drug adding function. Background Art

[0002] In the modern livestock breeding industry, in order to improve the nutritional value of feed and the health level of animals, two main types of feed are usually mixed: one is fermented pellet feed that has undergone microbial fermentation, which is rich in probiotics, enzymes and fermentation metabolites, and has the characteristics of loose structure, high water content and good water absorption; the other is industrial pellet feed that is precisely proportioned according to the nutritional needs of animals. It is rich in protein and energy, but has a compact structure, low water content and poor water absorption.

[0003] To improve feed quality, vitamins, minerals, and other pharmaceuticals are often added during the mixing process. In the feed mixing process, the commonly used procedure is to pre-mix the industrial pelleted feed with the liquid medicine before adding the fermented feed. However, since the fermented feed can only be added from the surface, it often takes a long time of stirring to achieve a uniform mixing effect after mixing. This process has two significant problems: first, excessive stirring time significantly reduces mixing efficiency; second, the industrial pelleted feed becomes loose in structure after mixing with the liquid medicine, while the fermented feed itself has a soft texture. Both are prone to breakage during the long stirring process, which not only affects the physical properties of the feed, but also reduces the animal's palatability and feeding efficiency, ultimately affecting the feeding effect. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing mixing process due to the difference in physical properties of the two feeds, which leads to uneven absorption of the drug solution, low mixing efficiency, too long stirring time, and easy feed breakage, affecting palatability and feeding efficiency, the present invention provides a feed mixing device with automatic drug addition.

[0008] As an improvement to the above scheme, the rotating assembly includes a third motor, a driving gear and a driven gear; a driven gear is provided on the upper side of the rotating tube; the third motor is fixedly connected to the feed hopper; the output end of the third motor is fixedly connected to the driving gear, the driving gear is engaged with the driven gear on the outside of the rotating tube, and the rotating tube is driven to rotate by the third motor.

[0009] As an improvement to the above solution, the spiral blade is in contact with the rubber portion.

[0010] As an improvement to the above solution, the rubber part is made of natural rubber, which has good wear resistance.

[0011] As an improvement to the above solution, a temperature and humidity sensor is further included; the temperature and humidity sensor is fixedly connected to the cover plate, and the probe of the temperature and humidity sensor extends into the interior of the mixing barrel.

At the same time, the spiral blades are in contact with the rubber part. When the drug solution flows downward along the wall of the fixed tube and the infusion tube, the spiral blades block it and then guide the downward-flowing drug solution onto the spiral blades, so that the drug solution flows downward along the surface of the spiral blades. This solves the problem that the drug solution flows downward out of the fixed tube along the inner wall of the fixed tube, resulting in the drug solution not being able to fully contact the industrial pelletized feed. At the same time, the drug solution and the industrial pelletized feed roll downward together on the surface of the spiral blades, thereby increasing the contact and absorption time between the industrial pelletized feed and the drug solution. The clockwise rotation of the spiral blade will drive the industrial pellet feed to move relatively upward. Therefore, workers can control the third motor to adjust the rotation speed of the rotating tube and the spiral blade, thereby controlling the speed at which the industrial pellet feed rolls downward, and thus controlling the contact time between the industrial pellet feed and the liquid medicine. The mixing time can be adjusted according to different types of feed to adapt to the mixing of different types of feed and liquid medicine, effectively improving the adaptability and practical value of the equipment.

[0023] The spiral blade 105 is in contact with the rubber portion 10601 .

[0024] The rubber part 10601 is made of natural rubber and has good wear resistance.

[0025] It also includes a temperature and humidity sensor 202 ; the temperature and humidity sensor 202 is fixedly connected to the cover plate 1001 , and the probe of the temperature and humidity sensor 202 extends into the mixing barrel 1 .

[0026] It also includes an exhaust pipe 201 ; the exhaust pipe 201 is fixedly connected to the cover plate 1001 , and the exhaust pipe 201 is connected to the mixing barrel 1 .

[0027] The working principle of the above embodiment is as follows: First, the worker connects the first feeding pipe 2 to the feeding equipment of the fermentation type pellet feed, and connects the second feeding pipe 3 to the feeding equipment of the industrial pellet feed. Then, the feeding equipment of the fermentation type pellet feed and the feeding equipment of the industrial pellet feed are started. The fermentation type feed enters the mixing barrel 1 through the first feeding pipe 2 and the rotating pipe 102, and the industrial pellet feed enters the mixing barrel 1 through the second feeding pipe 3, the feeding hopper 104 and the fixed pipe 101. In the initial state, Figure 2 As shown, at this time, the partition 203 is in a blocked state. After the fermented feed and the industrial granulated feed enter the mixing barrel 1, they will fall onto the partition 203. The stirring rod 205 is driven by the first motor 4 to rotate, and then the fermented feed and the industrial granulated feed on the partition 203 are fully stirred and mixed. After the feed mixing is completed, the rotating plate 204 is driven by the second motor 5 to rotate into the partition 203, and then the partition 203 is opened. At this time, the upper and lower sides of the partition 203 are in a connected state, and then as the stirring rod 205 continues to rotate, the feed on the upper side of the partition 203 will fall onto the discharge plate 206 and be discharged through the discharge port 1002.

[0028] Furthermore, in order to improve the quality of feed, vitamins, minerals and other pharmaceuticals are often added during the mixing process. However, in the feed mixing process, the commonly used operating procedure is to pre-mix the industrial pelletized feed with the medicinal solution first, and then add the fermented feed. However, since the fermented feed can only be added from the surface, it often takes a long time of stirring after the mixing is completed to achieve a uniform mixing effect. This process has two significant problems: first, the excessive stirring time significantly reduces the mixing efficiency; second, the industrial pelletized feed will become loose in structure after being mixed with the medicinal solution, and the fermented feed itself has a soft texture. Both are prone to breakage during the long stirring process, which not only affects the physical properties of the feed, but also reduces the palatability and feeding efficiency of the animals, and ultimately affects the feeding effect; therefore, the fermented feed and the industrial pelletized feed are added to the mixing barrel 1 respectively in a dual-channel manner, and the fermented feed is fed through the first feed barrel. Tube 2 and rotating tube 102 directly enter the mixing barrel 1, while the industrial pelletized feed enters the fixed tube 101 through the second feeding tube 3 and the feeding hopper 104, and then falls into the mixing barrel 1. When the industrial pelletized feed enters the fixed tube 101, the worker can add the medicinal liquid into the fixed tube 101 through the external infusion device, so that the industrial pelletized feed is pre-mixed with the medicinal liquid in the fixed tube 101. The mixed industrial pelletized feed will fall on the partition 203 together with the fermentation feed. At this time, the industrial pelletized feed is relatively moist after mixing with the medicinal liquid, and the industrial pelletized feed and the fermentation feed fall on the partition 203 relatively evenly. Therefore, there is no need to use the stirring rod 205 for long-term stirring and mixing. The stirring and mixing of the industrial pelletized feed, the fermentation feed and the medicinal liquid can be completed, thereby improving the stirring and mixing efficiency of the feed, preventing the fermentation feed from absorbing too much medicinal liquid, and avoiding the fermentation feed from being broken due to long-term stirring and mixing.

[0029] Considering that the industrial pellet feed has a compact structure and poor water absorption performance, and the industrial pellet feed falls from the fixed tube 101 to the partition 203 at a fast speed, it is difficult for the industrial pellet feed to fully absorb the liquid medicine in a short time, and the liquid medicine will flow down along the inner wall of the fixed tube 101 and out of the fixed tube 101 after being added to the fixed tube 101, resulting in the liquid medicine being unable to fully contact with the industrial pellet feed, thereby affecting the pre-mixing effect of the industrial pellet feed and the liquid medicine. Therefore, Figure 3-Figure 6 As shown, after the industrial pelletized feed enters the fixed tube 101, it will roll onto the surface of the spiral blade 105, and then roll downward along the spiral blade 105, thereby extending the residence time of the industrial pelletized feed in the fixed tube 101. At the same time, the liquid inlet tube 10701 is connected to the external infusion device, and the medicine liquid is sent into the infusion tube 106 through the liquid inlet tube 10701 and the connecting ring 107. Then, with the continuous pressurization of the external infusion device, the medicine liquid will slowly flow into the fixed tube 101 from the rubber part 10601 with the porous structure, so that the residence time of the industrial pelletized feed in the fixed tube 101 is extended. At the same time, the medicine liquid is slowly added into the fixed tube 101, and the spiral blade 105 contacts the rubber part 10601. When the medicine liquid flows downward along the wall of the fixed tube 101 and the infusion tube 106, it is blocked by the spiral blade 105, and then the downward flowing medicine liquid is guided to the spiral blade 105, so that the medicine liquid flows along the spiral blade 10 5, thereby solving the problem that the medicine liquid cannot fully contact with the industrial pellet feed due to the downward flow out of the fixed tube 101 along the inner wall of the fixed tube 101, and at the same time, the medicine liquid and the industrial pellet feed roll downward together on the surface of the spiral blade 105, thereby increasing the contact and absorption time of the industrial pellet feed and the medicine liquid; further, based on the view from top to bottom, the third motor 103 drives the driving gear 1031 to rotate clockwise, thereby driving the driven gear 1032 to rotate counterclockwise, thereby driving the rotating tube 102 and the first shifting rod 10201 to rotate, thereby causing the first shifting rod 10201 and the second shifting rod 10801 to rotate relative to each other, thereby shifting and breaking up the fermentation feed in the rotating tube 102, thereby avoiding the problem that the fermentation feed has a high water content and agglomerates, resulting in the agglomerated feed being difficult to fully mix with the industrial pellet feed in the subsequent process, thereby affecting the subsequent stirring and mixing effect.

[0030] Furthermore, when the third motor 103 drives the driving gear 1031 to rotate clockwise, and then drives the driven gear 1032 and the rotating tube 102 to rotate counterclockwise, the spiral blade 105 will also rotate counterclockwise. At this time, referring to the working principle of the screw conveyor, the spiral blade 105 will drive the industrial pelletized feed to move relatively upward after rotating counterclockwise. Therefore, the worker can adjust the rotation speed of the rotating tube 102 and the spiral blade 105 by controlling the third motor 103, thereby controlling the speed at which the industrial pelletized feed rolls down, and then controlling the contact time between the industrial pelletized feed and the liquid medicine, and then adjusting the mixing time according to different types of feed to adapt to the mixing of different types of feed and liquid medicine, thereby effectively improving the adaptability and practical value of the equipment.

[0031] On the basis of the above technical effects, the present invention also has the following advantages: like Figure 1 As shown, considering that during the mixing and stirring process of the feed and the liquid medicine, especially the chemical reaction between the fermented feed and the liquid medicine may produce a large amount of odor, which may cause harm to the workers' bodies after inhalation, the odor in the mixing barrel 1 is discharged through the exhaust pipe 201 on the cover 1001 during the stirring and mixing of the feed.

[0032] like Figure 1 As shown, temperature and humidity will affect the physical properties of feed raw materials, such as fluidity and viscosity. Under different temperature and humidity conditions, the mixing effect of feed raw materials during the stirring process may be different. The temperature and humidity in the mixing barrel 1 are monitored in real time by the temperature and humidity sensor 202, and the monitoring data is fed back to the staff, so that the staff can adjust the process parameters such as stirring time, stirring speed and dosage according to the actual situation to achieve the best mixing uniformity.

[0033] like Figure 6 As shown, the rubber portion 10601 is made of natural rubber, which has good wear resistance and effectively extends the service life of the infusion tube 106.

[0034] Example 2: Based on Example 1, Figure 3 and Figure 4 As shown, a material leveling block 109 is also included; the lower side of the fixed tube 101 is connected to the material leveling block 109; a guide portion 10901 is provided in the middle of the material leveling block 109, and the guide portion 10901 is a conical structure, and a discharge trough 10902 is provided in the circumference of the material leveling block 109.

[0035] The material leveling block 109 is fixedly connected to the rotating tube 102 , and the material leveling block 109 is rotatably connected to the fixed tube 101 .

[0036] The working principle of the above embodiment is as follows: like Figure 3As shown, when the fermentable feed falls out of the rotating tube 102 and the industrial pelletized feed falls out of the fixed tube 101, the fermentable feed and the industrial pelletized feed are simultaneously guided to the discharge trough 10902 by the guide portion 10901 having a conical structure, so that the fermentable feed and the industrial pelletized feed are pre-mixed in the discharge trough 10902 and then fall onto the partition 203, thereby making the fermentable feed and the industrial pelletized feed falling onto the partition 203 relatively uniform. Due to the improved pre-mixing effect, the working time of the stirring rod 205 can be shortened accordingly, thereby reducing the degree of damage to the feed during the stirring process of the stirring rod 205, improving the quality of the finished product of the mixed feed, and thus reducing the feed breakage rate.

[0037] On the basis of the above technical effects, the present invention also has the following advantages: like Figure 3 As shown, the material mixing block 109 is fixedly connected to the rotating tube 102, and the material mixing block 109 is rotatably connected to the fixed tube 101. Therefore, when the rotating tube 102 rotates, it will drive the material mixing block 109 to rotate, and then evenly sprinkle the feed in the discharge trough 10902 onto the partition 203, so as to prevent the material rolling out of the discharge trough 10902 from falling directly to the lower side of the material mixing block 109, causing the feed to accumulate on the lower side of the material mixing block 109. At the same time, through the rotation of the material mixing block 109, the feed in the discharge trough 10902 is centrifugally dispersed, effectively preventing the accumulation of wet feed in the discharge trough 10902.

[0038] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
