Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of stirring equipment, and relates to an easily-started mixer motor system with automatic protection function. BACKGROUND

[0002] The mixer is a kind of construction machinery, mainly used for stirring cement, sand, various dry powder mortar and other building materials. It is a machine with a blade shaft rotating in a cylinder or groove to stir and mix various raw materials into a mixture or suitable consistency. Mixers are divided into many types, such as forced mixer, single-shaft mixer, double-shaft mixer, etc. Mixers are divided into two types according to the operation mode, i.e. circulating operation type and continuous operation type.

[0003] The motor system is particularly important as the driving device of the mixer. In the existing motor system, the heat dissipation mode of the motor is mainly fan heat dissipation. When the motor is overloaded and overheats, the control circuit of the motor cannot be cut off in time, and the motor is easily damaged due to high temperature, which even endangers the life safety of the operator.

[0004] Therefore, it is necessary to design a device that can continuously cool down when the motor overheats within a certain range due to long-time work, and cut off the control circuit of the motor to stop the rotation of the motor and dissipate heat in time when the heat exceeds a certain limit.

[0005] To solve the above problems, the present application provides an easily-started mixer motor system with automatic protection function. SUMMARY

[0006] To solve the problems in the background art, the present application provides an easily-started mixer motor system with automatic protection function.

[0007] To achieve the above purpose, the technical scheme adopted by the present application is as follows: an easily-started mixer motor system with automatic protection function, comprising a mounting shell, a memory metal, a swing piece, a cooling piece, and a switch control piece; the motor is installed in the mounting shell; the cooling piece comprises a cooling pipe filled with cooling liquid, and the cooling pipe is arranged around the motor; the swing piece, the cooling piece, and the switch control piece are all installed in the mounting shell; the memory metal is installed between the motor and the swing piece; the memory metal changes its shape when heated, and drives the cooling piece to move towards or away from the motor direction through the swing piece, thereby controlling the switch control piece to adjust the on-off state of the motor; when the cooling piece moves, the swing piece presses the cooling piece, so as to replace the cooling liquid in the cooling pipe.

[0008] Further, the swing member comprises a fixed plate fixed in the mounting shell, two fixed rods fixed on the fixed plate, two telescopic members and a pressing plate; the middle part of each telescopic member is rotatably installed on the corresponding fixed rod; one end of each telescopic member is rotatably connected to the opposite ends of the pressing plate.

[0009] Further, the cooling member further comprises a storage tank, a water bag sealingly arranged on the storage tank and two one-way valves mounted on the storage tank; the water inlet end and the water outlet end of the cooling pipe are in communication with the storage tank through the two one-way valves respectively; the water bag is arranged towards the pressing plate.

[0010] Further, a through hole is formed in the fixed plate, and a memory metal is slidingly arranged in the through hole; one end of the memory metal is fixed on the motor, and the other end of the memory metal is fixed on the pressing plate.

[0011] Further, the switch control member comprises a switch controller and a wiring board; the switch controller is mounted on the storage tank through a connecting block, and the wiring board is mounted on the inner wall of the mounting shell and used in cooperation with the switch controller.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] 1. When the motor generates heat due to long-time work, and the heat value is within a certain range, the cooling pipe arranged on the motor can continuously cool the motor.

[0014] 2. When the motor generates heat due to long-time work, and the heat value exceeds the specified value, the memory metal deforms and drives the swing member and the cooling member to work, the cooling liquid in the cooling pipe after being heated enters the storage tank, the cooling liquid in the storage tank enters the cooling pipe; the cooling liquid in the cooling pipe continuously cools the motor again; at the same time, the memory metal changes the working state of the swing member and the cooling member due to the change of its own form, thereby adjusting the on-off state of the motor.

[0020] The cooling element includes a cooling pipe 3 , a storage tank 8 , a water bag 13 , and two one-way valves 7 ; the storage tank 8 stores four-fifths of its volume of cooling liquid 12 ; and the cooling pipe 3 is also filled with cooling liquid 12 .

[0021] In this embodiment, specifically, the cooling pipe 3 is wound around the motor 1; the water outlet end of the cooling pipe 3 is installed at the upper end of the storage box 8 through one of the one-way valves 7 and is connected to the storage box 8. The one-way valve 7 only allows the coolant 12 in the cooling pipe 3 to flow into the storage box 8; the water inlet end of the cooling pipe 3 is installed at the bottom end of the storage box 8 through another one-way valve 7 and is connected to the storage box 8. The one-way valve 7 only allows the coolant 12 in the storage box 8 to enter the cooling pipe 3.

[0022] The water bag 13 is sealedly connected to the storage tank 8 to form a sealed container.

[0023] More preferably, a heat exchange device is installed in the mounting shell 2, and the heat exchange device is connected to the storage tank 8; the heat exchange device can keep the coolant 12 in the storage tank 8 in a cooling state at all times.

[0024] The swing member includes a fixed plate 5 , two fixed rods 6 , two telescopic members 15 and a pressing plate 16 .

[0025] In this embodiment, specifically, the fixing plate 5 is fixed in the mounting shell 2 by bolts; the two fixing rods 6 are respectively fixed at the upper and lower ends of the fixing plate 5 and are arranged toward the water bag 13; the middle position of each telescopic member 15 is rotatably mounted on the corresponding fixing rod 6; one end of the two telescopic members 15 is respectively hinged to the upper and lower end portions of the pressure plate 16.

[0026] In this embodiment, one end of the two telescopic members 15 facing away from the pressing plate 16 is hinged to the storage; the pressing plate 16 is arranged toward the water bag 13 .

[0027] The telescopic part 15 comprises a cylinder shell, two limiting rings, two connecting rods with stepped portions and a spring.

[0028] In this embodiment, the stepped portions of the two connecting rods extend into the cylinder shell, and the stepped portions of the two connecting rods are oppositely arranged; the spring is installed in the cylinder shell and located between the stepped portions of the two connecting rods; the two limiting rings are respectively installed at the two ends of the cylinder shell to avoid the stepped portions of the connecting rods from extending out of the cylinder shell.

[0029] In this embodiment, a through hole is formed in the fixed plate 5, and the memory metal 4 is slidingly arranged in the through hole; one end of the memory metal 4 is fixed on the motor 1, and the other end of the memory metal 4 is fixed on the pressing plate 16.

[0030] The switch control part comprises a switch controller 9 and a wiring board 10.

[0031] In this embodiment, specifically, the switch controller 9 is installed on the side wall of the storage box 8 away from the water bag 13 through the connecting block 11, and the wiring board 10 is installed on the inner wall of the installation shell 2 and used in cooperation with the switch controller 9.

[0032] In use of this embodiment:

[0033] In the initial state, the motor 1 does not work, and the cooling liquid 12 is stored in the cooling pipe 3 and the storage box, and the switch controller 9 and the wiring board 10 are attached.

[0034] When the wiring board 10 is powered on, the motor 1 starts to work, and the switch controller 9 and the wiring board 10 are still attached; when the motor 1 heats up due to long-time work, the cooling liquid 12 in the cooling pipe 3 surrounding the motor 1 can cool the motor 1.

[0035] When the motor 1 works at a higher temperature, the cooling liquid 12 in the cooling pipe 3 cannot cool the motor 1 due to the increased temperature; at the same time, the memory metal 4 reaches the deformation condition, the memory metal 4 extends towards the end of the switch controller 9, and pushes the pressing plate 16 to move to the right, so that the pressing plate 16 drives the swing rod to rotate, and the swing rod drives the storage box to move to the left; then, the pressing plate 16 extrudes the water bag 13, and the cooling liquid 12 in the storage box enters the cooling pipe 3 through the lower one-way valve 7, so that the heated cooling liquid 12 in the cooling pipe 3 enters the storage box from the upper one-way valve 7, and the cooling and heating are alternated to cool the motor 1.

[0036] When the memory metal 4 deforms due to the temperature rise of the motor 1, the storage box moves to the left, so that the storage box drives the switch controller 9 to move to the left, and the switch controller 9 and the wiring board 10 are separated to make the motor 1 lose power.

[0037] When the temperature of the motor 1 is reduced to a certain value, the memory metal 4 restores its original shape, the storage box returns to the initial position, the switch controller 9 and the terminal plate 10 are attached, and the motor 1 is powered to continue working.

[0038] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
