Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] To enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0030] As Figure 1 and Figure 2 shown, a kind of unloading structure includes: a frame 2, a connecting rod assembly, and a material blocking plate group.

[0031] The mixing cylinder 1 is installed on the frame 2. The mixing cylinder 1 is used for stirring and mixing materials. A discharge port 3 is provided at the bottom of the mixing cylinder 1, and the stirred materials are discharged from the mixing cylinder 1 through the discharge port 3.

[0032] The lower part of the frame 2 is rotatably connected to the rotating shaft 4. The rotating shaft 4 is horizontally arranged and can rotate freely relative to the frame 2. The end of the rotating shaft 4 is connected to the connecting rod assembly. By driving the connecting rod assembly, the rotating shaft 4 rotates a certain angle, and then drives the blanking plate group 5 to move away from and block the discharge port 3.

[0033] The blanking plate group 5 is connected to the outer peripheral side of the rotating shaft 4. The blanking plate group 5 is arranged below the discharge port 3, and the top surface of the blanking plate group 5 can abut against the bottom surface of the discharge port 3, and the discharge port 3 is blocked by the blanking plate 503. It should be noted that the upper part of the blanking plate group 5 can rotate synchronously with the mixing cylinder 1, so as to ensure that the blanking plate group 5 can always be closely matched with the discharge port 3.

[0034] During operation, manually push and pull the driving arm 7. The driving arm 7 drives the rotating arm 6 to rotate a certain angle around the rotating shaft 4. The rotating arm 6 drives the rotating shaft 4 to rotate synchronously. The rotating shaft 4 drives the blanking plate group 5 to move, realizing the conversion between two position states of the blanking plate group 5 leaving and blocking the discharge port 3. The overall blanking structure is simple and convenient, not affected by dust in the working environment, and does not require regular maintenance, saving a certain amount of maintenance costs.

[0035] In an embodiment of the present invention, the connecting rod assembly includes: a rotating arm 6 and a driving arm 7. The first end of the rotating arm 6 is connected to the rotating shaft 4, and the second end of the rotating arm 6 is connected to the upper end of the driving arm 7. By applying a force to the upper end of the driving arm 7, the driving arm 7 drives the rotating arm 6 to rotate a certain angle around the rotating shaft 4, and the rotating shaft 4 rotates synchronously with the rotating arm 6.

[0036] A limiting component is arranged on the frame. The driving arm 7 is fixed by the limiting component. After changing the position of the driving arm 7, the position of the driving arm 7 can be locked in time by the limiting component, and manual fixing is not required.

[0037] Among them, two first limiting wedges 8 and second limiting wedges 9 with the same structure are arranged on the side of the frame 2. The first limiting wedge 8 and the second limiting wedge 9 are both fixed on the frame 2 by bolts. The first limiting wedge 8 and the second limiting wedge 9 are respectively used to connect the driving arm 7 in different position states. Further, when the upper end of the driving arm 7 is located at the position of the first limiting wedge 8, the blanking plate group 5 blocks the discharge port 3. At this time, the first driving motor drives the mixing cylinder 1 to rotate through the gear set to mix the materials. When the upper end of the driving arm 7 is located at the position of the second limiting wedge 9, the blanking plate group 5 moves away from the discharge port 3. At this time, the materials in the mixing cylinder 1 can be quickly discharged from the discharge port 3.

[0038] The surfaces of the first limiting wedge block 8 and the second limiting wedge block 9 are both provided with clamping grooves, and the clamping grooves are clamped and connected with the driving arm 7. Among them, the structure of the clamping groove is designed according to the structure of the driving arm 7, which can ensure that the driving arm 7 just fits into the clamping groove.

[0039] Preferably, an elastic gasket is arranged in the clamping groove. The elastic gasket is made of rubber material or can also be made of silica gel material. It is mainly used to increase the friction coefficient between the clamping groove and the driving arm 7, improve the connection stability between the clamping groove and the driving arm 7. On the other hand, the setting of the elastic gasket can prevent the driving arm 7 from directly contacting the clamping groove and reduce the wear of the driving arm 7.

[0040] A push-pull handle 10 is arranged at the upper end of the driving arm 7. When changing the position state of the driving arm 7, it is necessary to manually pull the driving arm 7 out of the clamping groove first, and then drive the driving arm 7 to rotate through the push-pull handle 10. Among them, the driving arm 7 is made of an elastic plate. When the driving arm 7 is clamped into the clamping groove, the driving arm 7 has a certain holding force on the first limiting wedge block 8 or the second limiting wedge block 9 under the action of its own elastic force, further ensuring that the driving arm 7 is stably clamped in the clamping groove.

[0041] Furthermore, the elastic plate is made of a metal material, and at the same time, the first limiting wedge block 8 and the second limiting wedge block 9 are also made of a magnetic material. When the driving arm 7 enters the clamping groove, the corresponding first limiting wedge block 8 and the second limiting wedge block 9 can have a certain magnetic attraction effect on the driving arm 7, further increasing the stability of limiting the driving arm 7.

[0042] As Figure 3 shown, the blanking plate group 5 includes: an assembly plate 501 sleeved on the outer peripheral side of the rotating shaft 4. The right end of the assembly plate 501 is connected to the rotating shaft 4, and the assembly plate 501 cannot rotate relative to the rotating shaft 4. At the same time, the other end of the assembly plate 501 is connected to the mounting frame 502, and the mounting frame 502 is connected to the blanking plate 503 to block the discharge port 3 through the blanking plate 503. Among them, the blanking plate 503 is designed according to the shape of the discharge port 3, not limited to rectangular or circular shapes.

[0043] The assembly plate 501 is rotatably connected to the mounting bracket 502, and one end of the assembly plate 501 is provided with a support plate 504. One end of the support plate 504 is rotatably connected to the lower end of the elastic telescopic rod 505, and the upper end of the elastic telescopic rod 505 is connected to one end of the mounting bracket 502. Among them, there is a certain acute angle between the top surface of the mounting plate and the top surface of the support plate. When the mounting bracket 502 gradually approaches the discharge port 3 driven by the assembly plate 501, one edge position of the top surface of the blanking plate 503 first contacts the discharge port 3, and the elastic telescopic rod 505 is connected at this edge position. When the top surface of the blanking plate 503 is completely in contact with the bottom surface of the discharge port 3, the elastic telescopic rod 505 is in a compressed state and has elastic potential energy. When the mixing drum 1 rotates at a high speed, even if there is looseness between the blanking plate 503 and the discharge port 3, the elastic telescopic rod 505 can still further hold the blanking plate 503 to ensure that the blanking plate 503 is tightly combined with the discharge port 3.

[0044] It should be noted that the discharge port 3 is coaxially arranged with the mixing drum 1. When the mixing drum 1 drives the discharge port 3 to rotate, the overall position of the discharge port 3 does not change, and the axis of rotation of the blanking plate 503 is coaxial with the mixing drum 1, further ensuring that the blanking plate 503 can always rotate synchronously with the discharge port 3.

[0045] Preferably, the middle part of the elastic telescopic rod 505 is a spring. The upper end of the spring is hinged to one end of the mounting bracket 502 through a first connecting rod, and the lower end of the spring is hinged to one end of the mounting bracket 502 through a second connecting rod. Of course, a structure similar to a shock absorber can also be directly selected as an alternative structure for the elastic telescopic rod 505. The shock absorber is a prior art and will not be elaborated herein.

[0046] The blanking plate 503 is rotatably connected to the mounting bracket 502. When the mixing drum 1 drives the discharge port 3 to rotate synchronously, the discharge port 3 can drive the blanking plate 503 to rotate synchronously to ensure that the blanking plate 503 always seals the discharge port 3. In addition, the top surface of the blanking plate 503 is parallel to the top surface of the mounting bracket 502. When the discharge port 3 drives the blanking plate 503 to rotate synchronously, the blanking plate 503 and the mounting bracket 502 do not contact each other, and the overall structure design of the blanking plate group 5 is more reasonable.

[0047] In addition, rubber gaskets are provided on the top surface of the blanking plate 503 and the top surface of the discharge port 3. After the blanking plate 503 is docked with the discharge port 3, the friction coefficient between the blanking plate 503 and the discharge port 3 is increased, and under the holding action of the mounting bracket 502, the blanking plate 503 and the discharge port 3 are more tightly combined.

[0048] In addition to the above manual discharging mechanism, the present invention also proposes a mixer including the manual discharging mechanism disclosed in the above embodiment. For the structures of other parts of the mixer, please refer to the prior art and will not be elaborated herein.

[0049] In addition, a feed inlet is provided at the top of the mixing cylinder 1. The stirred materials are added into the mixing cylinder 1 through the feed inlet. A sealing plate 12 is arranged at the position of the feed inlet. One side of the sealing plate 12 is rotatably connected to the mixing cylinder 1. The sealing plate 12 is mainly used to block the feed inlet of the mixing cylinder 1 to prevent the materials from spilling out of the mixing cylinder 1 when the first driving motor drives the mixing cylinder 1 to rotate.

[0050] As Figure 4 and Figure 5 shown, in an embodiment of the present utility model, a plurality of locking members 13 are arranged on the top surface of the sealing plate 12, and a plurality of locking buckles 11 are arranged on the top of the mixing cylinder 1. Each locking member 13 is snap-connected to a locking buckle 11. Through the cooperation of the locking buckle 11 and the locking member 13, the sealing plate 12 can be flexibly opened to complete feeding.

[0051] When the present utility model is in use, in the initial state, the clamping groove on the first limiting wedge 8 is connected to the upper end of the driving arm 7. At this time, the material blocking plate 503 blocks the discharge port 3, and materials can be conveyed into the mixing cylinder 1 through the feed inlet. When the mixing cylinder 1 needs to discharge materials through the discharge port 3, the upper end of the driving arm 7 is pulled by the push-pull handle 10. The upper end of the driving arm 7 is disengaged from the first limiting wedge 8, and the driving arm 7 is rotated counterclockwise. The driving arm 7 drives the rotating arm 6 to rotate counterclockwise, the rotating arm 6 drives the rotating shaft 4 to rotate counterclockwise, and the rotating shaft 4 drives the assembly plate 501 and the support plate 504 to rotate counterclockwise. The assembly plate 501 drives the material blocking plate 503 to gradually disengage from the discharge port 3 through the mounting bracket 502, and the discharge port 3 is opened to start discharging. The second limiting wedge 9 is snap-connected to the driving arm 7, and the discharge port 3 is in an always-open state.

[0052] It should be noted that when the mixing cylinder 1 finishes discharging materials through the discharge port 3, the upper end of the driving arm 7 is pulled by the push-pull handle 10. The upper end of the driving arm 7 is disengaged from the second limiting wedge 9, and the driving arm 7 is rotated clockwise. The driving arm 7 drives the rotating arm 6 to rotate clockwise, the rotating arm 6 drives the rotating shaft 4 to rotate clockwise, and the rotating shaft 4 drives the assembly plate 501 and the support plate 504 to rotate clockwise. The assembly plate 501 drives the material blocking plate 503 to gradually abut against the discharge port 3 through the mounting bracket 502 to complete the blocking of the discharge port 3. The driving arm 7 is snap-connected to the first limiting wedge 8, and the mixer starts a new round of work.

[0053] In summary, the material blocking plate group 5 is controlled to leave and block the discharge port 3 by manually pushing and pulling the driving arm 7, that is, the opening and closing state of the discharge port 3 is manually controlled by the principle of leverage. The overall discharging structure is simple and convenient, not affected by the dust in the working environment, has a wide application range, and does not require regular maintenance, effectively saving the maintenance cost.

[0054] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0055] Specific examples are used in this article to elaborate on the principles and implementation modes of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
