Description

Technical Field

[0001] The invention relates to the technical field of feed production and processing, and in particular to a rapid and uniform mixing device for feed production. Background Art

[0002] Feed is a general term for food for raising animals. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Common feed is in granular or powdered form. During the processing and production process, the raw materials need to be stirred and mixed.

[0003] The existing feed stirring and mixing equipment includes a stirring container and a stirring element rotating in the stirring container. Generally, when stirring, various raw materials are first poured into the stirring container, and then the rotation speed and stirring time of the stirring element are set. Through continuous rotation and stirring, the poured various raw materials are evenly mixed together.

[0004] The disadvantage of the existing stirring and mixing device for feed production is that although the existing feed stirring and mixing device can stir and mix multiple raw materials evenly, for feed production with a large number of raw materials and a complex formula, pouring multiple raw materials into the container at one time may not meet the requirements. At this time, the feed processing plant will adopt a batch mixing or stage mixing method, that is, after stirring and mixing multiple raw materials to a certain degree, add another raw material midway, and at this time, the raw materials that have been mixed in the container are piled together, and the raw materials added midway can only fall on the upper layer of the mixed raw materials inside the container. If uniform mixing is required, it can only rely on the stirring element to stir and mix continuously for a long time, which is difficult to ensure a uniform mixing effect, and the mixing efficiency is low.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention turns the mixing barrel upside down so that the feed raw materials that have been mixed to a certain degree flow from one side to the other side. During the flow, they pass through the material guide column arranged in the middle of the mixing barrel. The main spiral push rods distributed on the material guide column transport the mixed material downward in small amounts.

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1-Figure 5 As shown, a rapid and uniform mixing device for feed production includes a mixing drum 2, a feeding mechanism and a stirring shaft 7. The stirring shaft 7 is rotatably arranged at the center of the mixing drum 2 and is used to stir and mix the poured feed raw materials. A servo motor is provided at one end of the stirring shaft 7. By controlling the speed of the servo motor, it is convenient to control parameters such as the stirring speed. The feeding mechanism is arranged at a position close to the top of the mixing drum 2 and is used to introduce the feed raw materials to be stirred and mixed into the mixing drum 2. A discharge port 26 is provided at the bottom of the mixing drum 2, and a revolving door 27 that can be opened and closed is provided at the discharge port 26. The revolving door 27 is provided with a door lock. The mixing device also includes an inversion drive mechanism, a transition guide mechanism and a feeding mechanism.

[0032] The inversion drive mechanism is arranged outside the mixing drum 2, and is used to drive the mixing drum 2 to rotate upside down, so that when the feed raw materials are poured into the mixing drum 2 and stirred for a period of time, if the mixing drum 2 is turned upside down, the feed originally at one end will flow to the other end;

[0033] The transition material guide mechanism is arranged in the middle position inside the mixing drum 2, and the transition material guide mechanism includes a main spiral push rod 11. When the mixing drum 2 is turned upside down, the main spiral push rod 11 is used to gradually transport the feed raw materials in the mixing drum 2 from one side to the other side, and a linkage rotation mechanism is connected between the main spiral push rod 11 and the stirring shaft 7. During the rotation of the stirring shaft 7, it drives the main spiral push rod 11 to rotate together through the linkage rotation mechanism;

[0034] The feeding mechanism is arranged on the side wall of the mixing drum 2, and the feeding mechanism includes a secondary spiral push rod 14 for gradually adding feed raw materials into the mixing drum 2. In this way, when the mixing drum 2 is turned upside down, the main spiral push rod 11 gradually transports the feed raw materials in the mixing drum 2 from one side to the other side. In this process, the secondary spiral push rod 14 gradually transports a feed raw material added in the middle. In this way, the feed raw material added in the middle can be effectively mixed with the mixed feed that has been mixed in quantity, thereby ensuring a uniform mixing effect.

[0035] In some specific embodiments, such as Figure 1 As shown, the inversion mechanism includes a U-shaped support 1 and a stepper motor 6. The mixing drum 2 is rotatably connected to the inner side of the U-shaped support 1 through a horizontal rotating shaft. The stepper motor 6 is fixedly installed on one side outer wall of the U-shaped support 1. The stepper motor 6 is used to drive the mixing drum 2 to rotate upside down.

[0036] After several initial raw materials are added to the mixing drum 2 through the feeding mechanism and stirred and mixed for a certain period of time, if other raw materials need to be added midway, the mixing drum 2 is first driven to rotate by the stepping motor 6 to achieve upside-down rotation, so that the mixed material originally at one side of the mixing drum 2 flows to the other side during the inversion process, and is pushed gradually by the main spiral push rod 11 during the flow process, so as to facilitate effective mixing with the raw materials added midway gradually by the auxiliary spiral push rod 14.

[0037] In some specific embodiments, in combination Figure 2 , Figure 4 and Figure 5As shown, the transition material guiding mechanism divides the interior of the mixing barrel 2 into two upper and lower spaces. In the initial state, the several feed raw materials are stirred and mixed in the space on the downward side. The transition material guiding mechanism also includes a funnel guide barrel 9 and a material guiding column 10. The material guiding column 10 is located at the center of the mixing barrel 2. There are two funnel guide barrels 9, which are symmetrically distributed on the upper and lower sides of the material guiding column 10. The larger opening edge of the funnel guide barrel 9 is fixedly connected to the inner wall of the mixing barrel 2, and the funnel guide barrel 9 is also fixedly arranged relative to the material guiding column 10. The stirring shaft 7 passes through the center of the material guiding column 10 and can rotate relative to the material guiding column 10. In this way, it can be ensured that the stirring shaft 7 can stir both the upper and lower spaces. A plurality of material guiding channels 24 are opened circumferentially on the material guiding column 10. The material guiding channels 24 pass through the material guiding column 10. A plurality of main spiral push rods 11 are arranged, and they are correspondingly rotatably arranged in the material guiding channels 24.

[0038] In some specific embodiments, in combination Figure 2 and Figure 3 As shown, the linkage rotating mechanism includes a gravity inclined plane wheel 19 and a linkage slide. Two gravity inclined plane wheels 19 are provided and are respectively located on the upper and lower sides of the transition material guiding mechanism. The two gravity inclined plane wheels 19 are both slidably sleeved on the stirring shaft 7. The linkage slide is connected between the two gravity inclined plane wheels 19 to ensure that the two gravity inclined plane wheels 19 slide up and down synchronously. Both ends of each main spiral pushing rod 11 are coaxially fixedly connected with a first inclined plane linkage wheel 20 that matches the corresponding gravity inclined plane wheel 19. The first inclined plane linkage wheel 20 is truncated.

[0039] When the mixing drum 2 is in the initial vertical position, the downwardly directed gravity bevel wheel 19 is in a separated state from the first bevel linkage wheel 20 at the bottom of the main spiral push rod 11, while the upwardly directed gravity bevel wheel 19 is squeezed together with the first bevel linkage wheel 20 at the top of the main spiral push rod 11, and anti-skid grooves are distributed on the contact surfaces of the two. During the rotation of the stirring shaft 7, the gravity bevel wheel 19 at the upper position of the stirring shaft 7 contacts the first bevel linkage wheel 20 at the top of the main spiral push rod 11, and the gravity bevel wheel 19 rotates synchronously with the stirring shaft 7, thereby driving each first bevel linkage wheel 20 in contact. The surface linkage wheel 20 rotates, thereby causing each main spiral push rod 11 to rotate, and the raw materials are transported from top to bottom. At this time, the lower gravity inclined plane wheel 19 and the first inclined plane linkage wheel 20 at the bottom of the main spiral push rod 11 are in a separated state, thereby avoiding blocking the falling raw materials. It should be noted that each time the mixing drum 2 is turned upside down, the stirring shaft 7 can be controlled to reverse and adjusted according to actual needs. Since the main spiral push rod 11 is reversed synchronously, it is necessary to ensure that the direction of the main spiral push rod 11 conveying the material is always from top to bottom, so the stirring shaft 7 needs to be controlled to reverse.

[0040] Among them, the above-mentioned linkage slide includes a slide rod 21 and a strip slide 23. A cavity 22 is opened inside the stirring shaft 7, and the cavity 22 is located between the two gravity inclined plane wheels 19. The slide rod 21 is slidably arranged in the cavity 22, that is, the length of the cavity 22 is greater than the length of the slide rod 21. The strip slide 23 is opened outside the cavity 22, and the two are connected. The two ends of the slide rod 21 are respectively fixedly connected to the corresponding gravity inclined plane wheels 19 with connecting blocks passing through the strip slide 23. In this way, it can be ensured that the two gravity inclined plane wheels 19 can slide up and down synchronously relative to the stirring shaft 7, and can also rotate with the stirring shaft 7.

[0041] In some specific embodiments, in combination Figure 1 and Figure 2 As shown, there are multiple groups of feeding mechanisms, which are equidistantly distributed on the outer wall of the mixing barrel 2 in the circumferential direction. Each group of feeding mechanisms includes a feeding barrel 5 and a feeding pipe 12. The feeding barrel 5 is fixedly connected to the outer wall of the mixing barrel 2 and is aligned with the position of the guide column 10. The side of the feeding barrel 5 away from the mixing barrel 2 is open to facilitate the addition of raw materials. There are two feeding pipes 12, which are symmetrically fixed on the upper and lower sides of the feeding barrel 5. The upper and lower sides of the feeding barrel 5 are provided with inclined guide surfaces 13 corresponding to the feeding pipes 12. The end of each feeding pipe 12 is correspondingly penetrated into the transition guiding mechanism, specifically: the end of the feeding pipe 12 is exposed on the inner side of the funnel guide barrel 9 of the transition guiding mechanism. Each group of feeding mechanisms also includes two auxiliary spiral push rods 14, and the auxiliary spiral push rods 14 are correspondingly arranged in the feeding pipe 12 for rotation. A transmission mechanism is connected between each auxiliary spiral push rod 14 and the corresponding gravity inclined plane wheel 19.

[0042] Among them, the transmission mechanism includes a second inclined plane linkage wheel 17 and a transmission belt 18. The funnel guide cylinder 9 is fixedly connected to the shaft frame 16 at a position close to the feeding pipe 12. The second inclined plane linkage wheel 17 is rotatably connected to the shaft frame 16 through a rotating shaft. The gravity inclined plane rotor 19 includes two frustum bodies symmetrically distributed up and down, and the second inclined plane linkage wheel 17 and the first inclined plane linkage wheel 20 are respectively matched with the frustum bodies corresponding to the gravity inclined plane rotor 19. Each secondary spiral push rod 14 and the corresponding second inclined plane linkage wheel 17 are coaxially fixedly connected with a transmission wheel 15, and the transmission belt 18 is matched and connected between the two transmission wheels 15.

[0043] When it is necessary to add a raw material for mixing and stirring, the raw material can be put into the corresponding feeding barrel 5 after the mixing barrel 2 is turned upside down. At this time, due to the inversion, the two interconnected gravity inclined plane wheels 19 slide relative to the stirring shaft 7. After rotation, the corresponding frustum of the lower gravity inclined plane wheel 19 contacts the lower second inclined plane linkage wheel 17, and then drives it to rotate. The second inclined plane linkage wheel 17 drives the corresponding auxiliary spiral push rod 14 to rotate through the transmission wheel 15 and the transmission belt 18. In this way, the auxiliary spiral push rod 14 conveys the raw material added in the feeding barrel 5 gradually, so that it can be conveniently connected with the originally mixed raw material mixture flowing from top to bottom gradually. At the same time, under the stirring action of the stirring shaft 7, it is convenient to mix quickly, effectively and evenly.

[0044] In some specific embodiments, two groups of stirring blades 8 are provided on the stirring shaft 7, and the two groups of stirring blades 8 are distributed on the upper and lower sides of the transition material guiding mechanism, so as to facilitate stirring the upper and lower spaces of the transition material guiding mechanism respectively.

[0045] In some specific embodiments, such as Figure 2 As shown, there are multiple groups of feeding mechanisms, which are circumferentially distributed on the outer wall of the mixing barrel 2, near the top position. Each group of feeding mechanisms includes a charging barrel 3 and a material guiding inclined tube 4. The charging barrel 3 is distributed on the outside of the mixing barrel 2 and its opening faces upward. The bottom of the charging barrel 3 is funnel-shaped and is connected to the inside of the mixing barrel 2 through the material guiding inclined tube 4. When the raw materials need to be loaded into the mixing barrel 2 for stirring and mixing, the raw materials are first put into the charging barrel 3, and then enter the mixing barrel 2 along the inclined material guiding inclined tube 4.

[0046] It should be noted that an electrically controlled valve 25 is installed between the material guiding inclined tube 4 and the corresponding bottom of the loading barrel 3. When multiple raw materials need to be loaded at the same time in the initial state, in order to facilitate the flow of multiple raw materials into the mixing barrel 2 at the same time and facilitate mixing, different types of raw materials are respectively loaded into the loading barrels 3 at different positions. At this time, each electrically controlled valve 25 is ensured to be in a closed state. When the materials are loaded, all the electrically controlled valves 25 are opened at the same time for simultaneous feeding. A vibrator can also be installed on each loading barrel 3 to vibrate the feeding.

[0047] It should be noted that the maximum capacity of the feed mixed by the mixing drum 2 each time does not exceed the position of the lower second inclined linkage wheel 17.

[0048] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0049] First, the raw materials that need to be added for mixing at the beginning are loaded into the loading barrels 3 at different positions respectively. At this time, it is ensured that each electrically controlled valve 25 is in a closed state. When the materials are loaded, all the electrically controlled valves 25 are opened at the same time to feed the materials simultaneously. The various feed raw materials initially added first fall into the funnel guide barrel 9 near the upper position. At this time, the upper gravity inclined plane wheel 19 contacts the first inclined plane linkage wheel 20 at the top of the distributed main spiral pushing rod 11, driving each main spiral pushing rod 11 to rotate, so as to facilitate the various raw materials added at the beginning to be pushed downward gradually into the lower space inside the mixing barrel 2. At the same time, under the stirring action of the stirring shaft 7, it is convenient to effectively and evenly mix.

[0050] Then, after the various raw materials added at the beginning are stirred and mixed in the lower space inside the mixing drum 2 for a period of time, when it is necessary to add raw materials in the middle, the mixing drum 2 is driven by the stepping motor 6 to rotate upside down, and the stirring shaft 7 is controlled to reverse. At this time, the mixed material originally at one side of the mixing drum 2 flows to the other side during the inversion process, and passes through the position of the material guide column 10 during the flow process. During this process, the two gravity inclined plane wheels 19 slide synchronously relative to the stirring shaft 7 by means of the sliding rod 21. The gravity inclined plane wheel 19 that was originally in contact with the corresponding first inclined plane linkage wheel 20 is separated and rotated to the downward position. Then the other gravity inclined plane wheel 19 is rotated to the upward position and contacts with the corresponding first inclined plane linkage wheel 20. In this way, the main spiral pushing rod 11 can continue to push the mixed material from top to bottom in quantity, and at this time, the lower gravity inclined plane wheel 19 is in a separated state from the corresponding first inclined plane linkage wheel 20, thereby avoiding blocking and hindering the raw materials falling downward.

[0051] After the mixing barrel 2 is turned upside down, the raw materials that need to be added and mixed in the middle are put into the feeding barrel 5. While the stirring shaft 7 drives the gravity inclined plane wheel 19 to rotate, the frustum corresponding to the lower gravity inclined plane wheel 19 abuts against the lower second inclined plane linkage wheel 17, and then drives it to rotate. The second inclined plane linkage wheel 17 drives the auxiliary spiral push rod 14 at the lower position of the feeding barrel 5 to rotate through the transmission wheel 15 and the transmission belt 18. In this way, the auxiliary spiral push rod 14 gradually conveys the raw materials added in the feeding barrel 5, so that it is convenient to gradually intersect with the originally mixed raw material mixture that flows from top to bottom. At the same time, under the stirring action of the stirring shaft 7, it is convenient to quickly, effectively and evenly mix.

[0052] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
