Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and in particular to a screw wet-mix feeding equalizing device and its automatic control method. Background Art

[0002] During the transformation of the pig feeding method from free-choice dry feed to meal-feeding of liquid feed, porridge feed, wet-mix feed, and moist feed, various water-feed mixing feeding methods and equipment such as fully automatic, semi-automatic, and manual liquid feeding, porridge feed trucks, porridge feeders, porridge feed lines, mixing tanks for wet-mix feed, water spray wet-mix feed, and screw wet-mix feed have emerged in an endless stream. In order to overcome the many drawbacks of free-choice dry feed, people are trying every means to find a water-feed mixing feeding method suitable for the development of the contemporary pig industry. When the water-feed ratio is too low, the fluidity of the wet-mix feed decreases, making it easy for the feed to pile up, causing many pigs to gather together and frantically scramble for food, and there will be situations of biting and fighting with each other due to scrambling for food, resulting in serious feed waste; existing water-feed mixing feeding devices still have problems of uneven feeding at multiple feeding ports and inability to automatically control synchronous feeding, and cannot achieve the effect of enabling all pigs in the pen to eat at the same time.

[0003] Therefore, how to design a screw wet-mix feeding equalizing device and its automatic control method that can automatically control multiple feeding ports to open synchronously through a linkage device to achieve equal feeding of wet-mix feed is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a screw wet-mix feeding equalizing device and its automatic control method, aiming to solve at least one of the above technical problems; the present invention evenly distributes a plurality of feeding ports at equal distances on a mixing screw pipe to achieve equal feeding. An insertion plate is installed at each feeding port, and then each insertion plate is connected through a linkage device and automatically controlled through an electrical control device.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] On the one hand, the present invention provides a screw wet-mix feeding equalizing device, including:

[0007] A mixing screw pipe for transporting wet-mix feed; the mixing screw pipe is arranged horizontally, and an inlet is provided at the starting end of its conveying direction, an outlet is provided at the ending end of its conveying direction, and a plurality of feeding ports are arranged at intervals along the length direction on the lower side wall of the mixing screw pipe corresponding to the inlet and the outlet.

[0008] A gate plate assembly, and the gate plate assembly capable of opening and closing the feeding ports is provided at each of the plurality of feeding ports on the mixing screw pipe.

[0009] A linkage mechanism, wherein the linkage mechanism is connected to the plurality of gate assemblies to synchronously control the opening sizes of the plurality of gate assemblies;

[0010] A discharge detection component, which is arranged corresponding to the discharge port to detect the discharge state of the discharge port and can generate a non-discharge signal and a discharge signal;

[0011] A controller, the controller is electrically connected and can control the action of the linkage mechanism, thereby adjusting the opening size of the gate assembly; the controller is electrically connected to the discharge detection assembly, and can control the gate assembly to open the discharge port through the linkage mechanism when receiving the discharge signal, and control the gate assembly to close the discharge port through the linkage mechanism when receiving the non-discharge signal.

[0012] When the auger mixed wet material balanced feeding device of the present invention is in use, the controller can be used to control the action of the linkage mechanism to open and close the gate assembly and adjust the opening size of the gate assembly; the setting of the opening size of the gate assembly is determined according to the flow performance of the mixed wet material; the front gate assembly is adjusted to close all the discharge ports, and the mixing auger pipe is started to transport the mixed wet material until the discharge detection assembly detects that the discharge port is discharging material, and then the gate assembly is opened and the opening size of the gate assembly is adjusted synchronously, until the discharge amount of the mixing auger pipe is roughly equal to the feed amount and the discharge amount of each discharge port is roughly the same. Each time the device is started to feed, under the feeding condition of wet mixed material with the same fluidity, the same adjusted gate assembly opening is maintained; thereafter, when the wet mixed material is fed in balanced manner, the device is directly started and the conveying speed and feed amount of the mixing auger are controlled. When the material is discharged from the discharge port, the gate assembly will automatically open multiple feed ports for synchronous and balanced feeding; after the discharge port has finished discharging the material, the gate assembly closes the feed port; under the coordinated control of the controller, the present invention automatically controls the synchronous opening of multiple feed ports through a linkage device, thereby realizing multi-point balanced feeding of the wet mixed material.

[0013] As a further improvement of the above technical solution, the gate assembly includes a clamp discharge pipe head and a gate; the clamp discharge pipe head is clamped on the mixing auger pipe and corresponds to the discharge port, and the inner wall of the clamp discharge pipe head is provided with a discharge through hole corresponding to the discharge port; the gate plate surface is provided with a passing hole; the gate is arranged between the discharge port and the discharge through hole, and can adapt to block the discharge port and the discharge through hole; the gate can slide along the length direction of the mixing auger pipe, so that the passing hole corresponds to the discharge port and the discharge through hole.

[0014] The beneficial effects of the above technical solution are: the gate plate slidingly arranged along the length direction of the mixing auger pipe constitutes a valve for opening and closing the feed port and the discharge through hole; by adjusting the sliding displacement of the gate plate, the upper and lower corresponding areas of the feed hole, the feed port and the discharge through hole can be controlled, thereby realizing the adjustment of the opening size. The structural foundation for installing the gate plate is constructed by clamping the mixing auger pipe with the head of the clamp discharge pipe, which is simpler in structure and suitable for installation at different positions on the mixing auger pipe, and has better flexibility and adaptability in arrangement.

[0015] As a further improvement of the above technical solution, the linkage mechanism includes a stroke control mechanism and a linkage rod assembly; the linkage rod assembly is arranged along the length direction of the mixing auger tube and is transmission-connected to the gate of each gate assembly; the driving end of the stroke control mechanism is transmission-connected to the linkage rod assembly, and can control the sliding displacement of the gate of each gate assembly through the linkage rod assembly.

[0016] The beneficial effects of the above technical solution are: the stroke control mechanism can realize the opening and closing control of the discharge port by driving the gate plate to slide back and forth, and can adjust the opening degree of the discharge port by controlling the sliding displacement of the gate plate, thereby regulating the discharge amount.

[0017] As a further improvement of the above technical solution, the linkage rod assembly includes a plurality of linkage rods arranged along the length direction of the mixing auger tube; the plurality of linkage rods are arranged one-to-one between any two adjacent gate plates, and both ends of each linkage rod are connected to the ends of the corresponding gate plates; the driving end of the stroke control mechanism is transmission-connected to one of the linkage rods.

[0018] The beneficial effect of the above technical solution is that the driving end of the stroke control mechanism can synchronously drive multiple linkage rods and gate plates to move back and forth along the length direction of the mixing auger pipe.

[0019] As a further improvement of the above technical solution, the travel control mechanism includes a motor, a gear, a rack, a door opening travel switch and a door closing travel switch;

[0020] The rack is arranged along the length direction of the mixing auger tube and fixed on one of the linkage rods; the controller is electrically connected to the motor to control its operation; the gear is installed on the rotating shaft of the motor and is meshed with the rack; the door opening travel switch and the door closing travel switch are both electrically connected to the controller and arranged one by one at both ends of the length direction of the rack, thereby limiting the travel range of the rack.

[0021] The beneficial effects of the above technical solution are as follows: The motor can drive the gear to rotate forward or backward. The rotating gear can drive the rack to move back and forth. The rack drives multiple linkage rods to move back and forth in a linkage manner, thereby driving each gate to slide along the length direction of the mixing auger pipe. During the opening process of the gate, when one end of the rack in the length direction touches and presses the contact of the door-opening travel switch, the gate is opened in place and the motor stops running. During the closing process of the gate, when the other end of the rack in the length direction touches and presses the contact of the door-closing travel switch, the gate is closed in place and the motor stops running.

[0022] As a further improvement of the above technical solution, the discharge detection assembly includes a normally open photoelectric switch and a normally closed photoelectric switch; both the normally open photoelectric switch and the normally closed photoelectric switch are electrically connected to the controller; both the normally open photoelectric switch and the normally closed photoelectric switch are arranged corresponding to the discharge port to detect and feedback the discharge state of the discharge port.

[0023] The beneficial effects of the above technical solution are as follows: When the discharge port discharges, the normally open photoelectric switch closes and the normally closed photoelectric switch opens; when the discharge at the discharge port is completed, the normally open photoelectric switch opens and the normally closed photoelectric switch closes.

[0024] As a further improvement of the above technical solution, the controller includes an open contactor, a close contactor, an open switch, a close switch and a time relay;

[0025] The normally open contacts of the open contactor and the normally open contacts of the close contactor are connected between the motor and the power supply through wires to control the forward or reverse rotation of the motor;

[0026] The open switch, the normally open photoelectric switch, the normally closed contact of the door-opening travel switch, the normally closed contact of the close contactor and the coil of the open contactor are connected in series in turn and then connected to the power supply circuit to form an automatic door-opening control circuit;

[0027] The normally closed contact of the open contactor, the normally closed photoelectric switch and the coil of the time relay are connected in series in turn and then connected to the power supply circuit to form a delayed door-closing control circuit;

[0028] The close switch, the normally open contact of the time relay, the normally closed contact of the door-closing travel switch, the normally closed contact of the open contactor and the coil of the close contactor are connected in series in turn and then connected to the power supply circuit to form an automatic door-closing control circuit.

[0029] The beneficial effects of the above technical solution are as follows: The working process of the forward and reverse rotation of the motor is as follows: when the normally open contact of the door-opening contactor is closed, the normally open contact of the door-closing contactor is disconnected, and the power supply is electrically connected to the motor through the door-opening contactor to achieve the forward rotation of the motor; when the normally open contact of the door-closing contactor is closed, the normally open contact of the door-opening contactor is disconnected, and the power supply is electrically connected to the motor through the door-closing contactor to achieve the reverse rotation of the motor. The working process of the door-opening automatic control circuit is as follows: when the door-opening switch is closed and the material is discharged from the discharge port, the normally open photoelectric switch closes after sensing the discharge, and the normally closed photoelectric switch opens after sensing the discharge. There will be current in the power supply circuit passing through the door-opening switch, the normally open photoelectric switch, the normally closed contact of the door-opening travel switch, the normally closed contact of the door-closing contactor, and the coil of the door-opening contactor. After the coil of the door-opening contactor is energized, the normally open contact of the door-opening contactor closes, and the motor is energized and runs, and successively drives the gate to open through the gear, the rack, and the linkage rod assembly; when the end of the rack abuts and presses the contact of the door-opening travel switch, the normally closed contact of the door-opening travel switch is disconnected, the coil of the door-opening contactor loses power, and the motor stops rotating. Thus, the door-opening automatic control process is completed. The working process of the door-closing automatic control circuit is as follows: when the door-closing switch is closed and the discharging from the discharge port is completed, the normally open photoelectric switch opens after not sensing the discharge, and the normally closed photoelectric switch closes after not sensing the discharge; there will be current in the power supply circuit passing through the normally closed contact of the door-opening contactor, the normally closed contact of the normally closed photoelectric switch, and the coil of the time relay. After the coil of the time relay is energized, the normally open contact of the time relay closes. At this time, there will be current in the power supply circuit passing through the door-closing switch, the normally open contact of the time relay, the normally closed contact of the door-closing travel switch, the normally closed contact of the door-opening contactor, and the coil of the door-closing contactor. After the coil of the door-closing contactor is energized, the normally open contact of the door-closing contactor closes, and the motor is energized and runs, and successively drives the gate to close through the gear, the rack, and the linkage rod assembly; when the end of the rack abuts and presses the contact of the door-closing travel switch, the normally closed contact of the door-closing travel switch is disconnected, the coil of the door-closing contactor loses power, and the motor stops rotating. Thus, the door-closing automatic control process is completed. The working process of the delayed door-closing control circuit is as follows: after the mixing auger pipe finishes discharging, the normally closed photoelectric switch closes after not sensing the discharge; there will be current in the power supply circuit passing through the coil of the time relay. The coil of the time relay is energized and after a preset time, the normally open contact of the time relay closes, thereby triggering the door-closing automatic control; the time relay plays a role in delaying the door-closing action to ensure that the feed in the mixing auger pipe can be completely discharged.

[0030] As a further improvement of the above technical solution, the controller further includes a door-opening button and a door-closing button; the door-opening button and the coil of the door-opening contactor are successively connected in series and then connected to the power supply circuit to form a door-opening manual control circuit; the door-closing button and the coil of the door-closing contactor are successively connected in series and then connected to the power supply circuit to form a door-closing manual control circuit.

[0031] The beneficial effects of the above technical solution are as follows: Pressing the open door button can make the current output by the power supply circuit flow through the coil of the open door contactor, and then the normally open contact of the open door contactor is closed, starting the motor to drive the gate to open, and then opening the material discharge port; Pressing the close door button can make the current output by the power supply circuit flow through the coil of the close door contactor, and then the normally open contact of the close door contactor is closed, starting the motor to drive the gate to close, and then closing the material discharge port; By pressing and controlling the open door button and the close door button, the manual adjustment of the gate opening can be realized, and then the manual flexible control of the feeding amount of the material discharge port can be realized.

[0032] On the other hand, the present invention provides an automatic control method for a screw wet-mixed material balanced feeding device, including initial settings, and the specific steps are as follows:

[0033] Step 1: Close all the material discharge ports through the gate assembly, and start the mixing screw pipe to convey the wet-mixed material.

[0034] Step 2: When the discharge detection assembly detects the discharge at the discharge port, the controller controls the linkage mechanism to act, and then adjusts the opening degree of the gate assembly, so that the discharge amounts of each material discharge port are balanced. At this time, the opening degree of the gate assembly is set to the preset opening degree.

[0035] As a further improvement of the above technical solution, it also includes automatic control of material feeding, and the specific steps are as follows:

[0036] Step 1: The gate assembly is closed, and the mixing screw pipe is started to convey the wet-mixed material.

[0037] Step 2: When the discharge detection assembly detects the discharge at the discharge port, the controller controls the linkage mechanism to act, and then opens the gate assembly to the preset opening degree, so that each material discharge port discharges evenly.

[0038] Step 3: When the discharge detection assembly detects that the discharge at the discharge port stops, the mixing screw pipe has finished discharging, and the controller controls the linkage mechanism to act to close each material discharge port by the gate assembly.

[0039] It can be seen from the above technical solution that compared with the prior art, the present invention discloses a screw wet-mixed material balanced feeding device and its automatic control method, which has the following advantages and beneficial effects:

[0040] The relative positions of the discharging openings of each mixing auger pipe of the present invention and the plug plates should be set exactly the same, so as to facilitate the use of the same set of balanced feeding control device to control the discharging amounts of the discharging openings of all the mixing auger pipes in the circle to be basically the same. The present invention effectively solves the problem of unbalanced feeding of the auger wet-mixed feed; avoids the situation that when the water-to-feed ratio is too low, the fluidity of the wet-mixed feed is greatly reduced, causing the feed to pile up together, resulting in many pigs gathering together to frantically grab food, achieves the effect of enabling all pigs in the circle to eat at the same time, avoids the waste of feed and the situation of biting and fighting with each other due to grabbing food, and enables the smooth implementation of the feeding method of feeding the auger wet-mixed feed in separate meals. Thus, it can replace the traditional feeding method of free-choice dry feed and completely solve many problems existing in free-choice dry feed. BRIEF DESCRIPTION OF THE DRAWINGS

Each time the device is started for feeding, under the feeding condition of the wet-mixed material with the same fluidity, the adjusted opening degree of the gate assembly 2 is maintained; after that, when performing the balanced feeding of the wet-mixed material, the device is directly started and the conveying speed and feeding amount of the mixing auger pipe 1 are controlled.

The rotating shaft of the motor 311 passes through the plate surface of the motor fixing plate 3163 movably and is coaxially fixedly connected to the gear 312. The door-opening travel switch 314 and the door-closing travel switch 315 are both fixedly installed on the travel switch fixing plate 3162 by bolts and correspond to the two ends of the rack 313 in the length direction. The door-opening travel switch 314 and the door-closing travel switch 315 can be adjusted in the installation position along the length direction of the travel switch fixing plate 3162.

[0075] Specifically, the annular clamp 3161 includes a C-shaped sleeve 31611 and a bolt assembly 31612 for fastening and connecting the two open ends of the C-shaped sleeve together; both ends of the travel switch fixing plate 3162 and the motor fixing plate 3163 are detachably connected to the bolt assemblies 31612 of the two annular clamps 3161 in a one-to-one correspondence. The bolt assembly 31612 includes a screw rod and a plurality of nuts that are threadedly engaged with the screw rod.

[0076] In some embodiments, the discharge detection assembly 4 includes a normally open photoelectric switch 41 and a normally closed photoelectric switch 42; both the normally open photoelectric switch 41 and the normally closed photoelectric switch 42 are electrically connected to the controller 5; the normally open photoelectric switch 41 and the normally closed photoelectric switch 42 are both arranged corresponding to the discharge port 12 to detect and feedback the discharge state of the discharge port 12.

[0077] When the discharge port 12 discharges, the normally open photoelectric switch 41 closes and the normally closed photoelectric switch 42 opens; when the discharge at the discharge port 12 is completed, the normally open photoelectric switch 41 opens and the normally closed photoelectric switch 42 closes.

[0078] Specifically, the normally open photoelectric switch 41 and the normally closed photoelectric switch 42 are fixedly installed at the end of the mixing auger pipe 1 through a switch fixing bracket 43 and are arranged corresponding to the lower part of the discharge port 12; the functions of the normally open photoelectric switch 41 and the normally closed photoelectric switch 42 are to control the opening and closing of the feeding port 13 by detecting the on-off of the discharge flow.

[0079] In some embodiments, the controller 5 includes an open door contactor 51, a close door contactor 52, an open door switch 53, a close door switch 54, and a time relay 55;

[0080] The normally open contacts of the open door contactor 51 and the normally open contacts of the close door contactor 52 are connected between the motor 311 and the power supply 6 through wires to control the forward or reverse rotation of the motor 311;

[0081] The open door switch 53, the normally open photoelectric switch 41, the normally closed contacts of the open door travel switch 314, the normally closed contacts of the close door contactor 52, and the coil of the open door contactor 51 are connected in series in turn and then connected to the power supply circuit to form an automatic open door control circuit;

[0082] The normally closed contacts of the open door contactor 51, the normally closed photoelectric switch 42, and the coil of the time relay 55 are connected in series in turn and then connected to the power supply circuit to form a delayed close door control circuit;

[0083] The close door switch 54, the normally open contacts of the time relay 55, the normally closed contacts of the close door travel switch 315, the normally closed contacts of the open door contactor 51, and the coil of the close door contactor 52 are connected in series in turn and then connected to the power supply circuit to form an automatic close door control circuit.

[0084] Specifically, the controller 5 is installed in the electric control cabinet.

[0085] The working process of the forward and reverse rotation of the motor is as follows: when the normally open contact of the door-opening contactor 51 is closed, the normally open contact of the door-closing contactor 52 is disconnected, and the power supply 6 is electrically connected to the motor 311 through the door-opening contactor 51 to achieve the forward rotation of the motor 311; when the normally open contact of the door-closing contactor 52 is closed, the normally open contact of the door-opening contactor 51 is disconnected, and the power supply 6 is electrically connected to the motor 311 through the door-closing contactor 52 to achieve the reverse rotation of the motor. The working process of the automatic door-opening control circuit is as follows: when the door-opening switch 53 is closed and the material is discharged from the discharge port 12, the normally open photoelectric switch 41 closes after sensing the discharged material, and the normally closed photoelectric switch 42 opens after sensing the discharged material. There will be current in the power supply circuit passing through the door-opening switch 53, the normally open photoelectric switch 41, the normally closed contact of the door-opening travel switch 314, the normally closed contact of the door-closing contactor 52, and the coil of the door-opening contactor 51. After the coil of the door-opening contactor 51 is energized, the normally open contact of the door-opening contactor 51 closes, and the motor 311 is energized to operate and drives the gate plate 22 to open through the gear 312, the rack 313, and the linkage rod assembly 32 in sequence; when the end of the rack 313 abuts and presses the contact of the door-opening travel switch 314, the normally closed contact of the door-opening travel switch 314 is disconnected, the coil of the door-opening contactor 51 loses power, and the motor 311 stops rotating. Thus, the automatic door-opening control process is completed. The working process of the automatic door-closing control circuit is as follows: when the door-closing switch 54 is closed and the discharging at the discharge port 12 is completed, the normally open photoelectric switch 41 opens after not sensing the discharged material, and the normally closed photoelectric switch 42 closes after not sensing the discharged material; there will be current in the power supply circuit passing through the normally closed contact of the door-opening contactor 51, the normally closed contact of the normally closed photoelectric switch 42, and the coil of the time relay 55. After the coil of the time relay 55 is energized, the normally open contact of the time relay 55 closes. At this time, there will be current in the power supply circuit passing through the door-closing switch 54, the normally open contact of the time relay 55, the normally closed contact of the door-closing travel switch 315, the normally closed contact of the door-opening contactor 51, and the coil of the door-closing contactor 52. After the coil of the door-closing contactor 52 is energized, the normally open contact of the door-closing contactor 52 closes, and the motor 311 is energized to operate and drives the gate plate 22 to close through the gear 312, the rack 313, and the linkage rod assembly 32 in sequence; when the end of the rack 313 abuts and presses the contact of the door-closing travel switch 315, the normally closed contact of the door-closing travel switch 315 is disconnected, the coil of the door-closing contactor 52 loses power, and the motor 311 stops rotating. Thus, the automatic door-closing control process is completed. The working process of the delayed door-closing control circuit is as follows: after the mixing auger pipe 1 finishes discharging, the normally closed photoelectric switch 42 closes after not sensing the discharged material; there will be current in the power supply circuit passing through the coil of the time relay 55. After the coil of the time relay 55 is energized and after a preset time, the normally open contact of the time relay 55 closes, thereby triggering the automatic door-closing control; the time relay 55 plays a role in delaying the door-closing action to ensure that the feed in the mixing auger pipe 1 can be completely discharged.

[0086] In some embodiments, the controller 5 further includes an opening button 56 and a closing button 57; the opening button 56 and the coil of the opening contactor 51 are connected in series in sequence and then connected to the power supply circuit to form an opening manual control circuit; the closing button 57 and the coil of the closing contactor 52 are connected in series in sequence and then connected to the power supply circuit to form a closing manual control circuit.

[0087] Specifically, both the opening button 56 and the closing button 57 are installed inside the electric control cabinet.

[0088] Pressing the opening button 56 can make the current output from the power supply circuit flow through the coil of the opening contactor 51, and then make the normally open contact of the opening contactor 51 close, starting the motor 311 to drive the shutter 22 to open, and then opening the blanking port 13; pressing the closing button 57 can make the current output from the power supply circuit flow through the coil of the closing contactor 52, and then make the normally open contact of the closing contactor 52 close, starting the motor 311 to drive the shutter 22 to close, and then closing the blanking port 13; by pressing and controlling the opening button 56 and the closing button 57, the manual adjustment of the opening degree of the shutter 22 can be realized, and then the manual flexible control of the feeding amount of the blanking port 13 can be realized.

[0089] Specifically, the power supply 6 is a three-phase power supply; in practical applications, the power supply circuit can draw two live wires or one live wire and one neutral wire from the power supply 6 through wires to build the circuit.

[0090] Specifically, Figure 3 shows the automatic control circuit structure of a screw wet material equalizing feeding device of the present invention, where KM1 represents the coil of the opening contactor 51, KM 11 represents the normally open contact of the opening contactor 51, KM 12 represents the normally closed contact of the opening contactor 51, KM2 represents the coil of the closing contactor 52, KM 21 represents the normally open contact of the closing contactor 52, KM 22 represents the normally closed contact of the closing contactor 52, SQ1 represents the normally closed contact of the opening travel switch 314, SQ2 represents the normally closed contact of the closing travel switch 315, KT represents the coil of the time relay 55, KT1 represents the normally open contact of the time relay 55, Q1 represents the opening switch 53, Q2 represents the closing switch 54, M represents the motor 311; the motor 311 is a three-phase motor.

[0091] On the other hand, the present invention provides an automatic control method for a screw wet material equalizing feeding device, including initial settings, and the specific steps are as follows:

[0092] Step 1: Close all the blanking ports 13 through the shutter assembly 2, and start the mixing screw pipe 1 to convey the wet material for mixing;

[0093] Step 2: When the discharging detection component 4 detects the discharging at the discharging port 12, the controller 5 is used to control the action of the linkage mechanism 3, and then the opening degree of the gate plate component 2 is adjusted, so that the discharging amount of each blanking port 13 is balanced. At this time, the opening degree of the gate plate component 2 is set to the preset opening degree.

[0094] Specifically, the mixing auger pipe 1 is made of a transparent pipe, and transparent plastic or glass material can be selected.

[0095] Specifically, in Step 2, a plurality of gate plates 22 are used to completely plug and seal all the blanking ports 13 under the mixing auger pipe 1. The discharging port 12 at the end of the mixing auger pipe 1 always remains open. One end of the rack 313 is abutted against the contact head of the closing travel switch 315 to make it in the off state, and the closing travel switch 315 is fixed.

[0096] The feeding and water supply devices are turned on to supply materials and water into the mixing auger pipe 1, so that the mixing auger pipe 1 starts to feed and intake water and its auger is started. When the materials flow out from the discharging port 12 at the end, the normally open photoelectric switch 41 closes, and the normally closed photoelectric switch 42 opens. The motor 311 is powered on, and the gear 312 drives the rack 313, the linkage rod 321 and the gate plate 22 to move. The blanking port 13 is gradually opened and starts to discharge materials. At this time, the opening switch 53 is disconnected to cut off the power supply of the opening automatic control circuit, and the opening button 56 is pressed to control the motor 311 to slowly open the gate plate 22 until the discharging amount of the mixing auger pipe 1 is approximately equal to the feeding amount and the discharging amount of each blanking port 13 is approximately the same; when the blanking port 13 is opened too large and there is no discharging at the end discharging port 12, the closing switch 54 is disconnected to cut off the power supply of the closing automatic control circuit, and the closing button 57 is pressed to slowly close the gate plate 22 until the discharging amount is adjusted appropriately.

[0097] After the discharging amount of the mixing auger pipe 1 is adjusted appropriately, the contact head of the opening travel switch 314 is abutted against the other end of the rack 313 and the normally closed contact of the opening travel switch 314 is in the off state, and the opening travel switch 314 is fixed.

[0098] When the discharging of the mixing auger pipe 1 is completed, the normally open photoelectric switch 41 opens, and the normally closed photoelectric switch 42 closes. The motor 311 restarts and rotates in the opposite direction, driving the rack 313, the linkage rod 321 and the gate plate 22 to move through the gear 312, so that the blanking port 13 is closed. After the blanking port 13 is closed, the other end of the rack 313 touches the contact head of the closing travel switch 315 to cut off the circuit and stop the machine.

[0099] In some embodiments, automatic control of discharging is further included, and the specific steps are as follows:

[0100] Step 1: The gate plate component 2 is closed, and the mixing auger pipe 1 is opened to convey the wet mixed materials.

[0101] Step 2: When the discharge detection component 4 detects the discharge at the discharge port 12, the controller 5 controls the linkage mechanism 3 to act, so as to open the gate plate component 2 to a preset opening degree, so that the material is evenly discharged from each blanking port 13;

[0102] Step 3: When the discharge detection component 4 detects that the discharge at the discharge port 12 stops, the discharge of the mixing auger pipe 1 is completed, and the controller 5 controls the linkage mechanism 3 to act to close the gate plate component 2 at each blanking port 13.

[0103] Specifically, the relative positions of the blanking ports 13 of each mixing auger pipe 1 and the gate plate 22 should be set exactly the same, so as to use the same set of linkage mechanisms 3 with travel switches to control the discharge amounts of the blanking ports 13 of all the mixing auger pipes 1 in the circle to be basically the same.
