In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the utility model. In addition, the utility model can refer to the same reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0054] Reference Figure 1 , Figure 5 The application provides a mixing machine, which comprises a rack 100, a barrel member 200, a barrel cover assembly 300 and a stirring assembly 400. The rack 100 serves as a supporting base of the mixing machine and is used to be supported on an operation platform or the ground.

[0055] The barrel member 200 is rotatably connected to the rack 100, and the barrel member 200 and the rack 100 are arranged obliquely. During rotation of the barrel member 200, the raw materials are continuously lifted and then stirred by the stirring assembly 400, and then fall under the action of their own gravity. Through repeated lifting, stirring and falling, the mixing and stirring effect of the raw materials under the action of gravity is better, and the problem of adhesion of the raw materials to the inner wall of the mixing cavity is reduced.

[0056] The barrel cover assembly 300 is connected to the rack 100 and can be rotated at an angle with respect to the rack 100 in the up-down direction, so as to open or close the mixing cavity.

[0057] The barrel cover assembly 300 is connected to the rack 100 and can be rotated at an angle with respect to the rack 100 in the up-down direction, so as to open or close the mixing cavity.

[0058] The stirring assembly 400 comprises a stirring shaft 410 and stirring blades 420. A stirring driving member 330 is connected to the barrel cover assembly 300. The stirring shaft 410 is connected to the output end of the stirring driving member 330 and extends into the mixing cavity. The stirring blades 420 are dispersedly arranged on the outer wall of the stirring shaft 410.

[0059] With reference to Figures 2-4 The stirring assembly 400 is rotatably connected to the barrel cover assembly 300 by the stirring driving member 330, and the stirring assembly 400 is eccentrically arranged with the barrel member 200.

[0060] In other words, the rotation center of the stirring shaft 410 does not coincide with the center of the barrel member 200. Specifically, the stirring assembly 400 is arranged at an upper position in the barrel member 200 and is located upstream of the mixing cavity along the rotation direction of the barrel member 200.

[0061] When the barrel member 200 lifts the material upward from bottom to top, the material falls under the action of its own gravity after being further stirred by the stirring assembly 400. Thus, the material is dispersed and mixed more uniformly through repeated stirring.

[0062] During operation, the material in the mixing cavity is flipped upward to the corresponding stirring interval of the stirring assembly 400 along with the rotation of the barrel member 200, and is further mixed by the stirring blades 420.

[0063] With reference to Figure 6 At least the stirring blade 420 at the bottom of the stirring shaft 410 is formed with a material scraping end portion 430, and the outer side of the material scraping end portion 430 is formed with a conformal surface 431, which is shaped to match the transition surface 201.

[0064] Specifically, in order to facilitate batch production of the stirring blades 420, the material scraping end portion 430 is separately manufactured and connected to the end of the corresponding stirring blade 420 by welding. The welding method can avoid the connection gap generated during mechanical connection and facilitate cleaning of the material.

[0065] The conformal surface 431 matches the arc-shaped transition surface 201 formed on the bottom of the mixing cavity. That is, during relative rotation of the stirring assembly 400 and the mixing cavity, the material scraping end portion 430 scrapes the material on the bottom of the mixing cavity from the mixing cavity, avoiding the material adhering to the bottom of the mixing cavity and affecting the uniformity of the material mixing.

[0066] In some embodiments of the present application, each stirring blade 420 is formed with a material repelling surface, which gradually increases the thickness of the stirring blade 420 along the direction from the material facing surface to the material backing surface.

[0067] Therefore, during the material stirring process, the material repelling surface can reduce the resistance between the material and the stirring blade 420 and reduce energy loss.

[0068] The leading face of the material scraping end 430 is also formed with a guide surface 432 inclined to the center of rotation of the stirring shaft 410. In addition to reducing the resistance during the mixing and stirring of the material, the guide surface 432 can guide the material to the center of rotation of the stirring shaft 410, which is more conducive to the uniform mixing of the material at different positions in the mixing chamber and improves the stirring effect.

[0069] The stirring shaft 410 is eccentrically arranged with the barrel member 200, and each stirring blade 420 rotates in a preset stirring range. In the working state, the minimum gap d between the profiled surface 431 on the material scraping end 430 and the transition surface 201 satisfies 0.5mm≤d≤2mm, so as to avoid collision between the material scraping end 430 and the inner wall of the mixing chamber and damage to the equipment.

[0070] In some embodiments, a plurality of stirring layers are arranged along the axial direction of the stirring shaft 410, each stirring layer includes at least two stirring blades 420 uniformly distributed along the circumferential direction of the stirring shaft 410, and the stirring blades 420 on adjacent stirring layers are arranged in a staggered manner.

[0071] In some embodiments, each stirring layer includes two stirring blades 420 arranged in a 180-degree opposite manner, and the stirring blades 420 on adjacent two stirring layers are arranged in a staggered manner of 90 degrees.

[0072] Alternatively, the number of stirring blades 420 on each stirring layer can be three or more to improve the stirring effect.

[0073] The material scraping end 430 is arranged on the stirring layer located at the lowest position of the stirring shaft 410.

[0074] Since the material scraping end 430 continuously scrapes the material, the service life of the corresponding stirring blade 420 is shorter than that of the stirring blades 420 at other positions. In order to reduce the replacement cost, a connecting base 440 is detachably connected to the bottom of the stirring shaft 410 in some embodiments of the present application, the peripheral side of the connecting base 440 is formed with the stirring blades 420, and the material scraping end 430 is located on the connecting base 440.

[0075] The cross-sectional shape of the connecting base 440 corresponds to the stirring shaft 410. When the material scraping end 430 needs to be replaced due to serious wear, only the connecting base 440 needs to be replaced from the stirring shaft 410, avoiding the replacement of the entire stirring shaft 410, and reducing the maintenance and replacement cost.

[0076] The connecting base 440 is detachably connected with the stirring shaft 410. Specifically, a threaded hole is formed on the lower end surface of the stirring shaft 410, a through connecting hole is formed on the connecting base 440, and a fastener connects the connecting hole with the corresponding threaded hole to achieve the detachable connection of the connecting base 440 and the stirring blades 420.

[0077] In order to improve the stability of the connection, at least two threaded holes are arranged on the lower end surface of the stirring shaft 410 in a dispersed manner, and a corresponding number of connecting holes are arranged on the connecting base 440. The threaded segment of the fastener is screwed into the corresponding threaded hole through the corresponding connecting hole, so as to fix the connecting base 440.

[0078] Reference Figure 1 , Figure 2 and Figure 7 In some embodiments of the present application, the barrel cover assembly 300 is further provided with a scraping member 500, which includes a fixing seat 510 and a scraping plate 520 fixed below the fixing seat 510. The fixing seat 510 is connected with the barrel assembly, and the scraping plate 520 extends into the mixing cavity and is close to the inner wall of the mixing cavity. Specifically, the fixing seat 510 and the scraping member 500 are fixed integrally in advance by welding or mechanical connection. The fixing seat 510 is provided with a fixing hole, and the fixing seat 510 is detachably connected below the barrel cover 310 through the corresponding fixing hole, so that the scraping plate 520 extends downward along the inner wall of the mixing cavity. Similarly, a gap of 0.5mm to 2mm is also reserved between the scraping plate 520 and the inner wall of the mixing cavity to avoid interference between the barrel 200 and the scraping plate 520 during operation.

[0079] Reference Figure 3 , Figure 4 In the first rotation direction, the scraping member 500 is located downstream of the stirring assembly 400, and the material adhered to the inner wall of the mixing cavity can be scraped down to the mixing cavity by the scraping plate 520 and mixed with the remaining material.

[0080] Compared with the prior art, the scraping plate 520 is a vertical structure extending in the depth direction of the mixing cavity, and the original scraper is omitted. The resistance to the material is small, which is beneficial to reduce energy consumption, and can avoid the problem of the material meeting area of the traditional scraper extending transversely at the end of the scraping plate 520, which is beneficial to improve the uniformity of mixing.

[0081] In other embodiments, a material guide surface 521 inclined to the stirring interval direction is formed on the material meeting surface of the scraping plate 520, which can further transport the material scraped from the inner wall of the mixing cavity to the middle, further improving the uniformity of material mixing.

[0082] In some embodiments of the present application, with reference to Figures 8-10 The rack 100 specifically includes a support base 110 and a support stand 120. The bottom of the support base 110 is supported on the ground or a workbench, and the barrel 200 is fixed on the support base 110. The support stand 120 is arranged on the support base 110 and extends upward, and is used to connect the barrel cover assembly 300.

[0083] The barrel cover assembly 300 comprises a connecting base 320 and a barrel cover 310, the barrel cover 310 is fixed on the connecting base 320, the connecting base 320 is hinged on the support stand 120, and the barrel cover 310 is used to open or close the mixing cavity.

[0084] Specifically, a hinged convex part extending downward is formed on the connecting base 320, and the hinged convex part is hinged to the rear side of the support stand 120 through a rotating shaft, so that the connecting base 320 can be rotatably connected to the top of the support stand 120.

[0085] When the barrel cover 310 is opened, the connecting base 320 is flipped backward to open, so that the barrel cover 310 exposes the mixing cavity, facilitating the feeding of materials into the mixing cavity or the output of the mixed product.

[0086] The opening and closing of the barrel cover 310 is realized through a first driving member 340. Specifically, the first driving member 340 is formed on the support base 110, the fixed end of the first driving member 340 is hinged to the support base 110, and the telescopic end of the first driving member 340 is hinged to the support stand 120, which is used to drive the opening and closing of the barrel cover 310.

[0087] The first driving member 340 can be an electric push rod or a hydraulic cylinder, which controls the connecting base 320 through the telescopic end.

[0088] When the telescopic end of the first driving member 340 is shortened, the barrel cover 310 is closed forward with the rotating shaft as the center of rotation.

[0089] The telescopic end of the first driving member 340 is connected between the barrel cover 310 and the hinged convex part, and when the telescopic end of the first driving member 340 is lengthened, the barrel cover 310 is flipped backward and opened with the rotating shaft as the center of rotation.

[0090] When the barrel cover 310 is flipped backward and opened, the stirring assembly 400 is also flipped and moved upward in an arc, and the stirring assembly 400 and the hinged convex part are both positioned on the upper part of the barrel member 200, which can avoid the interference between the stirring assembly 400 and the barrel member 200 when the barrel cover 310 is opened, and increase the activity range of the stirring assembly 400.

[0091] The start and stop of the telescopic movement of the first driving member 340 is monitored through photoelectric detection. Specifically, a switch detection part 321 is formed on the barrel cover assembly 300, and the switch detection part 321 is specifically arranged on the connecting base 320.

[0092] The support base 110 is provided with a first photoelectric detection position 111 and a second photoelectric detection position 112. When the switch detection part 321 contacts the first photoelectric detection position 111, the barrel cover 310 is opened to the position. When the switch detection part 321 contacts the second photoelectric detection position 112, the barrel cover 310 is closed to the position.

[0093] The operation of the first driving part 340 on the mixer is controlled by a console. The console includes a controller and operation buttons. An operator triggers the operation buttons to control the operation of the first driving part 340, and further control the opening and closing of the barrel cover 310.

[0094] The first photoelectric detection position 111 and the second photoelectric detection position 112 are connected to the controller. When the first photoelectric detection position 111 detects that the switch detection part 321 moves to the position, the first photoelectric detection position 111 sends a to-position signal to the controller. The controller controls the first driving part 340 to stop elongation, and the barrel cover 310 is opened to the position.

[0095] When the second photoelectric detection position 112 detects that the switch detection part 321 moves to the position, the second photoelectric detection position 112 sends a to-position signal to the controller. The controller controls the first driving part 340 to stop contraction, and the barrel cover 310 is closed to the position.

[0096] The first photoelectric detection position 111 and the second photoelectric detection position 112 provide photoelectric control for the opening and closing of the barrel cover 310. The barrel cover limiting part 600 provides mechanical limiting for the closing of the barrel cover 310.

[0097] In addition, in other embodiments, the support base 110 is further provided with a moving guide groove 113. The moving guide groove 113 is arc-shaped. The first photoelectric detection position 111 and the second photoelectric detection position 112 are located at two ends of the moving guide groove 113. The switch detection part 321 is movably connected in the moving guide groove 113.

[0098] The switch detection part 321 is specifically a positioning rod structure fixed on the connecting base 320 and extending towards the support stand 120. The end is provided with a bent part connected into the moving guide groove 113. During the flipping of the connecting base 320, the bent part at the end of the switch detection part 321 moves along the moving guide groove 113.

[0099] The inclination angle of the barrel body 200 in the working state is 0-30 degrees. In order to facilitate unloading, the barrel body 200 can be further flipped downward by the second driving part 230 to more than 90 degrees, so that the opening of the mixing cavity faces downward, facilitating the output of the mixed material.

[0100] The second driving member 230 is arranged on the support base 110, a fixed end of the second driving member 230 is hinged to the support base 110, and an extension end of the second driving member 230 is hinged to the cylinder base 210, for driving the overturning and resetting of the cylinder member 200.

[0101] Specifically, the cylinder member 200 is rotatably connected to the support base 110 through the cylinder base 210, the extension end of the second driving member 230 is connected to the cylinder base 210, and the cylinder base 210 is further provided with a rotation driving member 220, the rotation driving member 220 is connected to the cylinder member 200, for driving the cylinder member 200 to rotate relative to the cylinder base 210 along a first rotation direction.

[0102] The rotation direction of the stirring assembly 400 can be the same as that of the cylinder member 200, both rotating along the first rotation direction, for example Figure 3 Alternatively, the rotation direction of the stirring assembly 400 can be opposite to that of the cylinder member 200, rotating along a second rotation direction opposite to the first rotation direction, and the specific rotation direction of the stirring assembly 400 can be specifically set or switched according to the mixing state of the material.
