[0029] like Figures 1 to 3 As shown, this embodiment provides a shaking and screening machine for disinfecting fresh mulberry leaves, and the shaking and screening unit includes: a support frame 101, which has a accommodating space; a drum 102, which is rotatably arranged in the accommodating space, and the drum 102 divides the accommodating space into a first space 103 and a second space 104, and a plurality of sieve holes 105 are opened on the drum 102; a disinfection unit is installed in the first space 103, and the disinfection unit is used to disinfect the leaves in the first space 103; a gas generating device, having a plurality of gas generators 301, and the plurality of gas generators 301 are evenly distributed on the inner wall of the drum 102, and the gas generators 301 blow the blades in the first space 103, and as the drum 102 rolls, the blades are driven to move, and the gas generator 301 emits gas to the blades, driving the blades to shake and rub against each other, so as to filter out impurities from the sieve holes 105.

[0030] In this embodiment, the support frame 101 is the basic support structure of the entire device, which is a frame structure, and its bottom is also provided with a support foot to ensure stability; the drum 102 is rotatably installed in the accommodation space of the support frame 101 through the bearing seats at both ends, the bearing seats are fixedly connected to the support frame 101, and corresponding sealing rings corresponding to the bearing seats are provided, so that the drum 102 can rotate smoothly in the support frame 101 and effectively seal the internal environment; the various components of the disinfection unit are fixed in the first space 103, directly connected to the support frame 101, and a sealing ring is provided between the drum 102, the compressor 302 of the gas generating device is installed in the support frame 101, and the gas cylinder 303 is arranged in the drum 102, and the connection is achieved through the connector 304 and the pipeline to ensure the delivery of gas. The water inlet valve 401 and the water outlet valve 402 are directly installed on the support frame 101 and are connected to the second space 104. When the device is started, the drum 102 starts to rotate. The rotation mode of the drum 102 can be adjusted according to different working stages. In the initial impurity removal stage, the drum 102 rolls slowly, and the gas generator 301 continuously blows gas to the blades. Since the gas generators 301 are evenly distributed on the inner wall of the drum 102, the blades continuously move and roll in the first space 103 under the dual effects of the rolling of the drum 102 and the blowing of gas. The blades shake and rub against each other, so that impurities such as mud, dust, etc. attached to the blades fall from the sieve holes 105 to the second space 104. In the cleaning stage, water is injected into the second space 104, and the water penetrates into the first space 103 through the sieve holes 105. At the same time, the gas generator 301 generates bubbles, and the bubbles flush and clean the blades during the rising process.

[0031] Furthermore, in some other implementation processes, the blades are shaken by controlling the drum 102 to rotate back and forth; and the drum 102 is controlled to rotate unidirectionally in coordination with the disinfection unit to perform disinfection.

[0032] In this embodiment, the drive device and the drum 102 are connected by a transmission mechanism, which can be a chain or a gear. The control center is connected to the drive device by a signal line, and can send a control signal to the drive device, thereby controlling the rotation of the drum 102 to include reciprocating rotation or unidirectional rotation. The disinfection unit is also connected to the control center by a signal line, and the control center can control the start and stop of the disinfection unit.

[0033] When the blades need to be shaken to remove impurities, the control center sends instructions to the drive device, and the drive device drives the drum 102 to reciprocate. The reciprocating rotation angle of the drum 102 can be set according to actual conditions, generally between ±30°-±60°, and the frequency of reciprocating rotation is 3-5 times per minute. In this process, the blades are constantly flipped and shaken in the drum 102, and the gas generator 301 continues to blow air, which enhances the friction and shaking effect between the blades, and is more conducive to the separation of impurities. When disinfection is required, the control center controls the drive device to make the drum 102 rotate unidirectionally, and the speed is generally 10-15 revolutions per minute. At the same time, the control center starts the disinfection unit, and the disinfection unit transports the disinfection liquid in the water tank 201 to the spray pipe 202 through the connecting pipe, and then the disinfection liquid is atomized by the atomizer and sprayed on the blades to achieve comprehensive disinfection of the blades.

[0034] Furthermore, in some other implementation processes, it also includes: a cover plate 106, which is rotatably set on the support frame 101, and a feeding port is set on the support frame 101, and the cover plate 106 seals the feeding port; a plurality of auxiliary blocks 107, which are evenly distributed on the inner wall of the drum 102, and the gas generator 301 is set on the auxiliary blocks 107; a driving device, which is transmission-connected to the drum 102, and the driving device is used to drive the drum 102 to rotate; a control center, which is set on the support frame 101, and the control center is communicatively connected with the driving device and the gas generator 301.

[0035] In this embodiment, the compressor 302 is fixedly installed in the support frame 101, and its gas outlet is connected to the connector 304 through a pipeline. The connector 304 is installed at the end of the roller 102 and is connected to the roller 102 through a rotating sealing structure to ensure the continuous delivery of gas to the rotating roller 102. The gas cylinder 303 is fixed in the auxiliary block 107 through a bracket and is connected to the connector 304 through a pipeline to achieve gas delivery. The gas generator 301 is connected to the gas cylinder 303 to convert the gas in the gas cylinder 303 into the required gas flow. The control center is specifically a PC processing center, which is used to process the information transmitted by the device and issue control instructions.

[0036] After the equipment is started, the compressor 302 starts to work, compresses the air and then delivers it to the connector 304 through the pipeline. As the drum 102 rotates, the rotary seal structure of the connector 304 can ensure that the gas is smoothly delivered to the gas cylinder 303 during the rotation of the drum 102. The gas pressure in the gas cylinder 303 gradually increases. When it reaches a certain pressure, the gas generator 301 starts to work and sprays the gas in the gas cylinder 303 through the gas generator 301. During the operation of the equipment, the compressor 302 continues to work, and according to the information fed back by the pressure sensor in the gas cylinder 303, the gas in the gas cylinder 303 is replenished in time to ensure that the gas generator 301 can continuously and stably blow air to the blades.

[0037] Furthermore, in some other implementation processes, the disinfection unit further includes: a water tank 201, which is arranged on the support frame 101, for containing the configured disinfection liquid; a spray pipe 202, which is provided with a plurality of atomizers, and one end of the spray pipe 202 is fixed on the inner wall of the first space 103, and the central axis of the spray pipe 202 coincides with the central axis of the drum 102; a connecting pipe, one end of which is connected to the water tank 201, and the other end is connected to the atomizer.

[0038] In this embodiment, the water tank 201 is fixed to the support frame 101 by a bracket, and a water outlet is provided at the bottom of the water tank 201, which is connected to one end of the connecting pipe. The other end of the connecting pipe is connected to the atomizer on the spray pipe 202 to realize the delivery of the disinfectant liquid. The spray pipe 202 is fixed to the inner wall of the first space 103 by a fixing member, ensuring that its central axis coincides with the central axis of the drum 102, so as to ensure that the disinfectant liquid can be evenly sprayed on the blades.

[0039] When disinfection is required, the control center controls the water pump to start, and the water pump draws out the disinfectant liquid in the water tank 201 and transports it to the spray pipe 202 through the connecting pipe. The disinfectant liquid flows in the spray pipe 202, and then is atomized into fine droplets by the atomizer and sprayed on the rotating blades. Since the central axis of the spray pipe 202 coincides with the central axis of the drum 102, as the drum 102 rotates, the blades can fully contact the disinfectant liquid, achieving effective disinfection. During the disinfection process.

[0040] Furthermore, in some other implementation processes, further, the gas generating device includes: a compressor 302, which is arranged in the support frame 101; a gas cylinder 303, which is arranged in the drum 102 and connected to the gas generator 301; a connector 304, which is arranged on the drum 102 and connected to the gas cylinder 303 through a pipeline, and the compressor 302 replenishes the gas in the gas cylinder 303 through the connector 304.

[0041] In this embodiment, the compressor 302 is fixedly installed in the support frame 101, and its gas outlet is connected to the connector 304 through a pipeline. The connector 304 is installed at the end of the drum 102 away from the cover plate 106, and the connecting pipelines of multiple gas cylinders 303 are converged to the central axis of rotation, and then connected to the drum 102 through a rotating sealing structure, which not only ensures the transportation of gas, but also does not hinder the rotation of the drum 102. The gas cylinder 303 is fixed in the drum 102 through a bracket, and is connected to the connector 304 through a pipeline to realize the transportation of gas. The gas generator 301 is connected to the gas cylinder 303 to convert the gas in the gas cylinder 303 into the required airflow.

[0042] After the equipment is started, the compressor 302 starts to work, compresses the air and then delivers it to the connector 304 through the pipeline. As the drum 102 rotates, the rotary seal structure of the connector 304 can ensure that the gas is smoothly delivered to the gas cylinder 303 during the rotation of the drum 102. The gas pressure in the gas cylinder 303 gradually increases. When it reaches a certain pressure, the gas generator 301 starts to work and sprays the gas in the gas cylinder 303 through the gas generator 301. During the operation of the equipment, the compressor 302 continues to work, and according to the information fed back by the pressure sensor in the gas cylinder 303, the gas in the gas cylinder 303 is replenished in time to ensure that the gas generator 301 can continuously and stably blow air to the blades.

[0043] Furthermore, in some other implementation processes, it further includes: a water inlet valve 401, which is arranged on the support frame 101, the water inlet valve 401 is connected to the second space 104, and the water inlet valve 401 is communicatively connected to the control center; a water outlet valve 402, which is arranged on the support frame 101, the water outlet valve 402 is communicated with the second space 104, and the water outlet valve 402 is communicatively connected to the control center.

[0044] In this embodiment, the water inlet valve 401 and the water outlet valve 402 are both connected to the second space 104 through a pipeline, and are respectively connected to the control center through a signal line. The water inlet valve 401 is connected to an external water source for injecting water into the second space 104; the water outlet valve 402 is used to discharge the water in the second space 104.

[0045] During the cleaning stage, the control center sends an opening signal to the water inlet valve 401, the water inlet valve 401 opens, and water from the external water source enters the second space 104 through the water inlet valve 401. As the water is continuously injected, the water level of the second space 104 gradually rises, and the water penetrates into the first space 103 through the sieve holes 105 on the drum 102 to clean the blades. When the cleaning is completed, the control center sends an opening signal to the water outlet valve 402, the water outlet valve 402 opens, and the water in the second space 104 is discharged through the water outlet valve 402. The water outlet valve 402 is provided with a first water outlet valve higher than the drum 102 and a second water outlet valve at the lowest position. In the process of cleaning the disinfected blades, when the liquid is higher than the drum 102, it will bring debris and other processed impurities to the water surface, and the upper half of the water body containing impurities will be discharged through the first water valve to achieve flow cleaning and remove impurities, and the remaining water body will be released through the second water outlet valve to achieve efficient control of discharge. The control center can accurately control the opening and closing time of the water inlet valve 401 and the water outlet valve 402 according to the preset time or the information fed back by the water level sensor to ensure the smooth progress of the cleaning process.

[0046] Furthermore, in some other implementation processes, a heating component is provided to heat the inside of the gas cylinder 303 to air-dry the cleaned blades.

[0047] In this embodiment, the heating component is installed in the gas cylinder 303 and is connected to the control center through a signal line. The control center can control the opening and closing of the heating component and the heating power.

[0048] When the blades are cleaned, the control center starts the heating component, which heats the gas in the gas cylinder 303. The heated gas is ejected through the gas generator 301 to form hot air. At this time, the drum 102 continues to rotate slowly, and the hot air circulates in the drum 102 to air-dry the blades. The control center adjusts the heating power of the heating component and the rotation speed of the drum 102 according to the information fed back by the humidity sensor of the blades to achieve the best air-drying effect. When the humidity of the blades reaches the preset standard, the control center turns off the heating component and the drum 102 to complete the entire disinfection, cleaning and air-drying process.

[0049] In summary, by setting the drum 102 to shake the blades, the damage caused by the mechanical vibration of the traditional screen plate is reduced, and different processes can be adapted according to the leaves of different maturity; the blades are flipped by the spray beam generated by the gas generator 301 to improve the removal of attachments on the surface of the blades; the disinfection unit cooperates with the rotation of the drum 102 and the flipping of the blades by the gas generator 301 to improve the efficiency of disinfection; the second space 104 is filled with water, and the blades are actively flipped by cooperating with the drum 102, and then the blades are further rinsed by the gas generating device, and the blade surface is fully cleaned by the continuously generated bubbles.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
