Description
Technical Field
[0001] This utility model belongs to the technical field of mixing devices, and specifically relates to a feed mixing device that eliminates dead angles in mixing. Background Technology
[0002] A feed mixing device is a mechanical device used to uniformly mix different feed ingredients, primarily in the livestock industry. Its working principle is to use mechanical mixing to thoroughly mix various raw materials in a specific ratio, ensuring animals receive balanced nutrition. However, existing feed mixing devices often experience mixing dead zones during operation. This is mainly due to unsuitable numbers, shapes, and positions of the mixing blades, resulting in some areas not being effectively mixed. This leads to uneven feed mixing, reduced feed quality, and consequently, reduced farming efficiency. Conventional solutions involve using more advanced mixing technologies, such as high-speed mixing or hydrodynamic mixing, to improve mixing efficiency. While this method can solve the problem of mixing dead zones, its drawbacks include the need for technical support and personnel training, which can be a burden for small-scale farming enterprises. Furthermore, personnel training takes time, increasing time costs. Therefore, a new structure is proposed to address these issues. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feed mixing device that can mix feed without dead angles.
[0004] This utility model is achieved through the following technical solution: a feed mixing device with no dead angles, comprising: a device shell, a stabilizer and a mixing assembly, wherein the top of the device shell is provided with a top cover, and a stabilizer is provided inside the upper part of the device shell, the stabilizer being composed of a stabilizing cylinder and two sets of connecting rods;
[0005] The stabilizer is provided with a stirring tank below it and a drive shaft above it. The top of the drive shaft extends upward through the top cover, and the bottom of the drive shaft passes through the inside of the stabilizer cylinder and extends downward to the bottom of the stirring tank. Three sets of stirring components are arranged in sequence from top to bottom below the stabilizer.
[0006] The stirring assembly consists of a fixed sleeve, clamping plates, and stirring blades. The fixed sleeve is fixedly sleeved on the outside of the drive shaft. Three sets of clamping plates are welded at equal intervals on the outside of the fixed sleeve. Each set of clamping plates is inclined downward at a 30-degree angle in a clockwise direction. Each set of clamping plates is provided with a set of stirring blades on its outside.
[0007] In a preferred embodiment, a feed inlet is provided through the front side of the top of the top cover, and a motor is provided on the top of the top cover. The output end of the motor at the bottom is connected to the top of the transmission shaft through a coupling.
[0008] In a preferred embodiment, the outer side of the drive shaft does not contact the inner side of the stabilizing cylinder. The inner side of the stabilizing cylinder is provided with several sets of rolling grooves from top to bottom, and several sets of rolling balls are embedded in each set of rolling grooves.
[0009] In a preferred embodiment, the side of the rolling groove closest to the drive shaft is connected to the inner side of the stabilizing cylinder. The balls are made of stainless steel, and the outer sides of several sets of balls contact the inner side of the drive shaft. The outer side of the stabilizing cylinder is welded and fixed to the inner wall of the device housing by two sets of connecting rods. In actual use, the upper section of the drive shaft is placed inside the stabilizer. When the drive shaft rotates inside the device housing, it will vibrate due to centrifugal force, affecting the stability of the drive shaft. Therefore, the stabilizer can effectively increase the stability of the drive shaft during rotation. Secondly, when the drive shaft rotates inside the stabilizing cylinder, the outer side of the drive shaft contacts the outer side of several sets of balls, thereby rubbing against the outer side of several sets of balls during rotation. This causes several sets of balls to roll inside the rolling groove, thus avoiding direct contact between the outer side of the drive shaft and the inner side of the stabilizing cylinder. By rolling the balls inside the rolling groove, the friction generated when the drive shaft rotates is greatly reduced, thereby improving the stability of the drive shaft rotation and making the drive shaft rotate more smoothly and effortlessly.
[0010] In a preferred embodiment, the stirring assembly is provided in three identical sets, which are equidistantly distributed from top to bottom along the outer side of the drive shaft, with the interval between the uppermost and lowermost stirring assemblies being less than the depth of the stirring tank.
[0011] In a preferred embodiment, each set of clamping plates consists of an upper clamping plate and a lower clamping plate. The stirring blade is inserted between the upper and lower clamping plates on the side near the fixed sleeve. The stirring blade and the clamping plates are connected and fixed by a fixing mechanism.
[0012] In a preferred embodiment, the stirring blades are made of stainless steel and are inclined downwards at a 30-degree angle clockwise. The radius of the circular area formed by the three sets of stirring blades matches the radius of the mixing tank. In actual use, the rotation of the drive shaft drives the three sets of fixed sleeves installed sequentially from top to bottom below the drive shaft to rotate. This, in turn, drives the three sets of clamping plates to rotate, which in turn drives the three sets of nine stirring blades to rotate. Each set of fixed sleeves has three sets of clamping plates distributed on its outer side, and each set of clamping plates has a set of stirring blades fixed to its outer side by a fixing mechanism. The stirring blades are inclined downwards at a 30-degree angle clockwise, giving them a better angle to cut into the feed, thus facilitating the mixing of the feed. The uppermost stirring assembly mixes the feed in the upper layer of the mixing tank, the middle stirring assembly mixes the feed in the middle layer of the mixing tank, and the lowermost stirring assembly mixes the feed in the lower layer of the mixing tank. Thus, the three sets of stirring assemblies respectively mix the upper, middle, and lower layers of feed inside the mixing tank, preventing the formation of dead zones and improving the mixing quality and efficiency.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting a drive shaft and three sets of stirring components, the three sets of stirring components are installed equidistantly from top to bottom on the outside of the drive shaft. When the drive shaft rotates, the drive shaft drives the three sets of fixed sleeves to rotate, thereby driving the three sets of clamping plates to rotate through the three sets of fixed sleeves, and then driving the three sets of stirring blades to rotate. The design of the stirring blades tilting downwards at a 30-degree angle along clockwise can give the stirring blades a better cutting angle, thus facilitating the full mixing of feed. The three sets of stirring components set from top to bottom can fully mix the feed in the upper, middle and lower layers of the mixing tank respectively, so that there are no dead corners in the mixing, thereby improving the quality of feed mixing and thus improving work efficiency. By setting a stabilizer, the rotation of the drive shaft can be made more stable. The drive shaft rotates inside the stabilizer, driving several sets of balls to roll inside the rolling groove, thereby reducing the friction between the drive shaft and the inside of the stabilizer, making the rotation of the drive shaft more labor-saving.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figures 1 to 4 A feed mixing device with no dead angles includes: a device shell 100, a stabilizer 120 and a mixing assembly 140. The top of the device shell 100 is provided with a top cover 200, and the stabilizer 120 is provided inside the upper part of the device shell 100. The stabilizer 120 is composed of a stabilizing cylinder and two sets of connecting rods.
[0024] A stirring tank 130 is provided below the stabilizer 120, and a drive shaft 110 is provided above the stabilizer 120. The top of the drive shaft 110 extends upward through the top cover 200, and the bottom of the drive shaft 110 passes through the inside of the stabilizer cylinder and extends downward to the bottom of the stirring tank 130. Three sets of stirring components 140 are arranged from top to bottom below the stabilizer 120.
[0025] The stirring assembly 140 consists of a fixed sleeve 141, clamping plates 142, and stirring blades 143. The fixed sleeve 141 is fixedly sleeved on the outside of the drive shaft 110. Three sets of clamping plates 142 are welded at equal intervals on the outside of the fixed sleeve 141. Each set of clamping plates 142 is inclined downward at a 30-degree angle in the clockwise direction. Each set of clamping plates 142 is provided with a set of stirring blades 143 on the outside.
[0026] The top cover 200 has a feed inlet 210 through the front side of the top, and a motor 220 is installed on the top of the top cover 200. The output end of the bottom of the motor 220 is connected to the top of the drive shaft 110 through a coupling.
[0027] The outer side of the drive shaft 110 does not contact the inner side of the stabilizer cylinder. Several sets of rolling grooves 121 are opened on one side from top to bottom on the inner side of the stabilizer cylinder. Several sets of balls 122 are embedded in each set of rolling grooves 121.
[0028] The rolling groove 121, near the drive shaft 110, is connected to the inner side of the stabilizer cylinder. The balls 122 are made of stainless steel, and several sets of balls 122 have their outer sides in contact with the inner side of the drive shaft 110. The outer side of the stabilizer cylinder is welded and fixed to the inner wall of the device housing 100 via two sets of connecting rods. In actual use, the upper section of the drive shaft 110 is placed inside the stabilizer 120. When the drive shaft 110 rotates inside the device housing 100, it will vibrate due to centrifugal force, affecting the stability of the drive shaft 110. Therefore, the stabilizer 120 can effectively increase the stability of the drive shaft 110 during rotation. When the secondary drive shaft 110 rotates inside the stabilizing cylinder, the outer side of the drive shaft 110 contacts the outer side of several sets of balls 122, thereby causing friction between the drive shaft 110 and the outer side of the balls 122 as the drive shaft 110 rotates. This causes the balls 122 to roll inside the rolling groove 121, thus avoiding direct contact between the outer side of the drive shaft 110 and the inner side of the stabilizing cylinder. By having the balls 122 roll inside the rolling groove 121, the friction generated when the drive shaft 110 rotates is greatly reduced, thereby improving the stability of the drive shaft 110's rotation and making the rotation of the drive shaft 110 smoother and less strenuous.
[0029] The stirring assembly 140 has three identical sets, which are distributed at equal intervals from top to bottom along the outer side of the drive shaft 110. The interval between the uppermost stirring assembly 140 and the lowermost stirring assembly 140 is less than the depth of the stirring tank 130.
[0030] Each set of clamping plates 142 consists of an upper clamping plate and a lower clamping plate. The stirring blade 143 is inserted between the upper and lower clamping plates on the side near the fixed sleeve 141. The stirring blade 143 and the clamping plates 142 are connected and fixed by a fixing mechanism 144.
[0031] The stirring blades 143 are made of stainless steel and are inclined downwards at a 30-degree angle clockwise. The radius of the circular area formed by the three sets of stirring blades 143 matches the radius of the stirring tank 130. In actual use, the rotation of the drive shaft 110 drives the three sets of fixed sleeves 141 installed sequentially from top to bottom below the drive shaft 110 to rotate. This, in turn, drives the three sets of clamping plates 142 to rotate, which in turn drives the three sets of nine stirring blades 143 to rotate. Each set of fixed sleeves 141 has three sets of clamping plates 142 distributed on its outer side, and each set of clamping plates 142 is fixed by a fixing mechanism. A set of stirring blades 143 is fixed in place, and the stirring blades 143 are tilted downward at a 30-degree angle in the clockwise direction, so that the stirring blades 143 have a better angle to cut into the feed, which facilitates the stirring of the feed. The uppermost set of stirring components 140 stirs the feed in the upper layer of the stirring tank 130, the middle set of stirring components 140 stirs the feed in the middle layer of the stirring tank 130, and the lowermost set of stirring components 140 stirs the feed in the lower layer of the stirring tank 130. Thus, the three sets of stirring components 140 stir the upper, middle and lower layers of feed in the stirring tank 130 respectively, preventing the formation of stirring dead corners.
[0032] Example 1: Please refer to Figures 1 to 3 In actual use, after the motor 220 starts, it drives the transmission shaft 110 to rotate via the coupling (the internal structure and working principle of the motor 220 and the coupling are existing technologies, and their models can be selected according to needs, which will not be elaborated here). The rotation of the transmission shaft 110 drives the three sets of fixed sleeves 141 installed below the transmission shaft 110 from top to bottom to rotate, thereby driving the three sets of clamping plates 142 to rotate through the three sets of fixed sleeves 141, which in turn drives the three sets of nine stirring blades 143 to rotate. Three sets of clamping plates 142 are distributed on the outside of each set of fixed sleeves 141, and a set of stirring blades is fixed on the outside of each set of clamping plates 142 by a fixing mechanism 144. The mixing blade 143 is tilted downward at a 30-degree angle in a clockwise direction, so that the mixing blade 143 has a better angle to cut into the feed, which facilitates the mixing of the feed. The uppermost set of mixing components 140 mixes the feed in the upper layer of the mixing tank 130, the middle set of mixing components 140 mixes the feed in the middle layer of the mixing tank 130, and the lowermost set of mixing components 140 mixes the feed in the lower layer of the mixing tank 130. Thus, the three sets of mixing components 140 mix the upper, middle and lower layers of feed in the mixing tank 130 respectively, preventing the formation of mixing dead corners and improving the mixing quality and mixing efficiency.
[0033] Example 2: Please refer to Figure 2 and Figure 4When the drive shaft 110 rotates, the upper section of the drive shaft 110 is placed inside the stabilizer 120. When the drive shaft 110 rotates inside the housing 100 of the device, it will vibrate due to the centrifugal force, affecting the stability of the drive shaft 110. Therefore, the stabilizer 120 can effectively increase the stability of the drive shaft 110 when it rotates. Secondly, when the drive shaft 110 rotates inside the stabilizer, the outer side of the drive shaft 110 contacts the outer side of several sets of balls 122, thereby rubbing against the outer side of the balls 122 when the drive shaft 110 rotates, thereby driving the balls 122 to roll inside the rolling groove 121. This avoids direct contact between the outer side of the drive shaft 110 and the inner side of the stabilizer. By rolling the balls 122 inside the rolling groove 121, the friction generated when the drive shaft 110 rotates is greatly reduced, thus improving the stability of the drive shaft 110 rotation and making the drive shaft 110 rotate more smoothly and effortlessly.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
