Description

Technical Field

[0001] The invention relates to the technical field of breeding, and in particular to an automatic feeder. Background Art

[0002] At present, the prospects for my country's animal husbandry industry are optimistic, but the breeding technology is still relatively traditional. Most of them are done by manually mixing and proportioning feed and feeding it multiple times. This method is time-consuming, labor-intensive and inefficient. In addition, the feeding amount cannot be accurately controlled, resulting in too little or too much feeding, which is not conducive to the growth of livestock. Summary of the invention

[0003] In view of the above problems, the object of the present invention is to provide an automatic feeder which can feed feed at a fixed time and in a fixed quantity, can automatically feed feed without multiple manual feeding, and will not be blocked by feed.

[0004] The specific technical solutions are as follows:

[0005] An automatic feeder includes a feed trough, a bracket, a silo, a controller, and a discharger, a transition bin, and a feed pipe installed between the feed trough and the silo; the feed trough is arranged at the bottom; the silo is supported and fixed above the feed trough by a bracket, and a top cover is also arranged on the top of the silo; the discharger is installed at the feed outlet at the bottom of the silo and driven by a driving motor Ma; the transition bin is fixed at the bottom of the discharger and connected to the bottom of the discharger; the feed pipe is a plurality of pipes with upper and lower openings and located above the feed trough, the upper end of each feed pipe is fixed at the bottom of the transition bin and connected to the transition bin, and the lower end extends directly above the feed trough; the controller is installed outside the silo and is electrically connected to the drive motor Ma of the discharger through a wire to control the timed automatic feeding or timed automatic stopping of the discharger. An automatic feeder can feed two to four livestock (such as pigs); loading once can feed livestock for about 15 days, and a 9A battery is installed in the automatic feeder, which can supply power for 3-5 days after a power outage.

[0006] Furthermore, the unloader is a star-shaped unloader or a screw conveyor. The star-shaped unloader is similar to a conventional star-shaped unloader. The top of the unloader is directly connected to the bottom of the silo, and the bottom is connected to the top of the transition silo. The interior is composed of a shaft connected to the drive motor Ma and blades evenly fixed on the shaft. The area between two adjacent blades constitutes a loading area. During unloading, the blades rotate with the shaft of the drive motor Ma, and after the feed carried in the loading area is brought to the top of the transition silo, the feed automatically falls to achieve unloading, that is, quantitative unloading can be effectively achieved through the rotation of the blades in the unloader. The screw conveyor is a conventional screw reamer conveyor. The feed end of the screw conveyor is directly connected to the bottom of the silo, and the discharge end is connected to the top of the transition silo. Driven by the drive motor Ma, the feed is continuously lowered by the screw reamer.

[0007] Furthermore, the controller is equipped with an automatic control circuit for controlling the unloader to automatically unload or stop materials at a fixed time; the automatic control circuit includes a main circuit and a control circuit; the main circuit includes an AC or DC power supply, a main switch Q, a normally open main contact KM-1 of the contactor KM, a thermal relay FR, and a drive motor Ma; wherein the normally open main contact KM-1 of the contactor KM is connected between the main switch Q and the thermal relay FR, and the other end of the thermal relay FR is connected to the winding of the drive motor Ma; after the normally open main contact KM-1 of the contactor KM is turned on, the drive motor Ma is powered on and rotates. The control circuit includes the break contact FR-1 of the thermal relay FR and a fuse FU2 connected between the control circuit and the fuse FU1. One end of the break contact FR-1 is connected to the L2 phase of the AC power supply, and the other end is connected to one end of the time relay KT1; the other end of the time relay KT1 is connected to one end of the normally closed contact KT2-1 of the time relay KT2; the other end of the normally closed contact KT2-1 of the time relay KT2 is connected to the L1 phase of the AC power supply. The other end of the break contact FR-1 is also connected to one end of the relay KA; the other end of the relay KA is connected to one end of the contactor KM; the other end of the contactor KM is connected to one end of the normally closed contact KT1-1 of the time relay KT1; the other end of the normally closed contact KT1-1 of the time relay KT1 is connected to the L1 phase of the AC power supply. The other end of the break contact FR-1 is also connected to one end of the time relay KT2; the other end of the time relay KT2 is connected to one end of the normally closed contact KA-1 of the relay KA; the other end of the normally closed contact KA-1 of the relay KA is connected to the L1 phase of the AC power supply. The circuit breaker, transformer, and battery (9A battery, the storage capacity of which can be used by the automatic feeder for 3 to 5 days after a power outage) are connected in sequence between the AC or DC power supply and the main switch.

[0008] In the automatic control circuit, the time relay KT1 is used to control the feeding time, and then indirectly control the feeding amount. The setting value of the delay time on the time relay KT1 is determined according to the size of the livestock, the number of feeding pipes, the specifications of the unloader (unloader speed and the feeding amount per unit time), etc. The time relay KT2 is used to control the time interval between two adjacent feedings. The setting value of the delay time on the time relay KT2 is determined according to the number of daily feedings, which is generally more than 3 hours. The contactor KM is used to directly control the start and stop of the drive motor Ma, the reduction motor Mb, and the heating device K.

[0009] Furthermore, a scattering device is provided in the transition bin. When the amount of feed discharged by the discharger is too large, if it is not scattered, it is easy to concentrate in large quantities at the top of a certain feeding pipe, resulting in blockage of the top of the feeding pipe, and then making feeding unsmooth. The existence of the scattering device can effectively disperse the feed particles concentrated in a certain area through the scattering device before entering the feeding pipe, which can effectively avoid clogging the feeding pipe and ensure smooth feeding; the scattering device is composed of a plurality of scattering frames and a reduction motor arranged side by side from left to right in the transition bin. Mb; each scattering frame includes a shaft, a side rod, and a transmission gear; the shaft is rotatably installed in the transition bin and its end extends out of the transition bin; the side rod is a plurality of rod bodies that are obliquely or vertically fixed on the outer periphery of the shaft and rotate with the shaft; a plurality of auxiliary rods are also provided on the outer periphery of each side rod; the transmission gear is fixed on the end of the shaft and is located outside the transition bin; the reduction motor Mb is installed outside the transition bin, and a driving gear that meshes with the transmission gear on one of the scattering frame shafts is provided on the rotating shaft of the reduction motor Mb.

[0010] Furthermore, the reduction motor Mb is connected to the main circuit of the automatic control circuit through a wire, and is connected in parallel with the drive motor Ma to the other end of the thermal relay FR; the reduction motor Mb and the drive motor Ma are started and stopped synchronously under the control of the automatic control circuit.

[0011] Furthermore, an anti-blocking device is provided in the discharge pipe; the anti-blocking device is composed of a plurality of discharge wheels arranged in parallel from top to bottom in the discharge pipe; the discharge wheel comprises a support shaft, a sleeve shaft, a blade, and a driven gear; the support shaft is transversely fixed in the discharge pipe; the sleeve shaft is rotatably sleeved on the support shaft and one end thereof extends out of the discharge pipe; the blade is a plurality of plates installed on the outer circumference of the sleeve shaft and rotate with the sleeve shaft in the discharge pipe (in the preferred embodiment, the number of plates is three or four and they are evenly installed on the outer circumference of the sleeve shaft); the driven gear is located outside the discharge pipe and fixed on the end of the sleeve shaft extending out of the discharge pipe, the driven gears of adjacent discharge wheels are meshed with each other, and the driven gear on the uppermost discharge wheel is meshed with the transmission gear on the scattering device.

[0012] Furthermore, each plate of the blade is composed of a plurality of rods fixed vertically side by side on the sleeve shaft, and the spacing between two adjacent rods on each plate is equal to or greater than the diameter of the rod; the blades on two adjacent discharge wheels are longitudinally crossed (saving space), and when rotating, the rods on the blades on the two discharge wheels do not contact each other (when rotating, the rod of the lower discharge wheel rotates into the gap between the rods of the upper discharge wheel to scrape off the feed stuck in the gap between the rods of the upper discharge wheel). This arrangement can not only avoid blockage inside the discharge pipe.

[0013] Furthermore, it also includes a heating device K for automatically heating the feed. The purpose of setting the heating device K is that when the temperature is low, the temperature of the feed stored in the silo will decrease, and putting the feed in the trough will affect the normal eating of the livestock, reduce the livestock's food intake, affect the normal growth of the livestock, and even make the livestock sick; the heating device K is connected to the main circuit of the automatic control circuit through a wire, and is connected in parallel with the drive motor Ma to the other end of the thermal relay FR; a start switch is set on the circuit where the heating device K is located. When the temperature is low, the start switch is pressed to connect the heating device K to the automatic control circuit and automatically start and stop under the control of the automatic control circuit.

[0014] Furthermore, an insulating heat-insulating plate is provided on the outer wall of the feed tube to reduce heat loss; the support shaft, sleeve shaft, blade, and driven gear are all made of metal materials and have good thermal conductivity; the support shaft is a hollow tube with one end open and the other end closed, and the open end of the support shaft is fixed on the inner wall of the feed tube and connected to the outside of the feed tube; the heating device K is an electric heating rod, and the structure and principle of the electric heating rod are the same as those of the electric heating plate, using electric heating alloy wire as the heating material, mica soft board as the insulating material, and wrapped with a thin metal plate (aluminum plate, stainless steel plate, etc.) for heating. The fixed end of the tail of the electric heating rod is installed on the outer wall of the feed tube corresponding to the support shaft, and the head heating end extends into the support shaft from the open end of the support shaft.

[0015] Furthermore, protective covers are provided on both sides of the front and rear of the feeding pipe and the front side of the transition bin to protect the gears and the heating device K, prevent the heating device K from being damaged by livestock, and prevent the heating device K from leaking electricity.

[0016] The automatic feeder of the present invention can realize automatic timing and quantitative feeding of feed without multiple manual operations, can not only effectively break up the feed to prevent blockage, but also can heat the feed while automatically feeding the feed when the temperature is low, thereby increasing the feed temperature and promoting the feeding of livestock.

[0030] Embodiment 1:

[0031] like Figure 1-3 As shown, an automatic feeder of the present invention comprises a trough 1, a bracket 2 (the bracket 2 is composed of a plurality of vertical rods and transverse rods), a silo 6, a controller, and a discharger 5, a transition bin 4, and a feed pipe 3 installed between the trough 1 and the silo 6; the trough 1 is arranged at the bottom; the silo 6 is supported and fixed above the trough 1 by the bracket 2, and a top cover is also provided on the top of the silo 6; the discharger 5 is installed at the discharge port at the bottom of the silo 6 and driven by a driving motor Ma; the transition bin 4 is fixed at the bottom of the discharger 5 and communicated with the bottom of the discharger 5; the feed pipe 3 is a plurality of pipes with upper and lower openings and located above the trough 1, and the upper end of each feed pipe 3 is fixed at the bottom of the transition bin 4 and connected to the transition bin 4, and the lower end extends directly above the trough 1; the controller is installed outside the silo 6 and is electrically connected to the driving motor Ma of the discharger 5 through a wire to control the timed automatic feeding or timed automatic stopping of the discharger 5. The discharger 5 is a star discharger or a screw conveyor. The star-shaped unloader is similar to the conventional star-shaped unloader. The top of the unloader is directly connected to the bottom of the silo 6, and the bottom is connected to the top of the transition bin 4. The interior is composed of a shaft connected to the drive motor Ma and blades evenly fixed on the shaft. The area between two adjacent blades constitutes the loading area. When unloading, the blades rotate with the shaft of the drive motor Ma, and after the feed carried in the loading area is brought to the top of the transition bin 4, the feed automatically falls to achieve unloading, that is, quantitative unloading can be effectively achieved through the rotation of the blades in the unloader 5. The screw conveyor is a conventional screw reamer conveyor. The feed end of the screw conveyor is directly connected to the bottom of the silo 6, and the discharge end is connected to the top of the transition bin 4. Driven by the drive motor Ma, the feed is continuously lowered through the screw reamer.

[0032] like Figure 8As shown, the controller is equipped with an automatic control circuit for controlling the unloader 5 to automatically unload or stop materials at a fixed time; the automatic control circuit includes a main circuit and a control circuit; the main circuit includes an AC or DC power supply, a main switch Q, a normally open main contact KM-1 of the contactor KM, a thermal relay FR, and a drive motor Ma (a 120W DC motor); wherein the normally open main contact KM-1 of the contactor KM is connected between the main switch Q and the thermal relay FR, and the other end of the thermal relay FR is connected to the winding of the drive motor Ma; after the normally open main contact KM-1 of the contactor KM is turned on, the drive motor Ma is energized and rotated. The control circuit includes the break contact FR-1 of the thermal relay FR and the fuse FU2 connected between the control circuit and the fuse FU1. One end of the break contact FR-1 is connected to the L2 phase of the AC power supply, and the other end is connected to one end of the time relay KT1; the other end of the time relay KT1 is connected to one end of the normally closed contact KT2-1 of the time relay KT2; the other end of the normally closed contact KT2-1 of the time relay KT2 is connected to the L1 phase of the AC power supply. The other end of the break contact FR-1 is also connected to one end of the relay KA; the other end of the relay KA is connected to one end of the contactor KM; the other end of the contactor KM is connected to one end of the normally closed contact KT1-1 of the time relay KT1; the other end of the normally closed contact KT1-1 of the time relay KT1 is connected to the L1 phase of the AC power supply. The other end of the break contact FR-1 is also connected to one end of the time relay KT2; the other end of the time relay KT2 is connected to one end of the normally closed contact KA-1 of the relay KA; the other end of the normally closed contact KA-1 of the relay KA is connected to the L1 phase of the AC power supply. The circuit breaker, transformer, and battery (9A battery) are connected in sequence between the AC or DC power supply and the main switch.

[0033] In the automatic control circuit, the time relay KT1 is used to control the feeding time, and then indirectly control the feeding amount. The setting value of the delay time on the time relay KT1 is determined according to the size of the livestock, the number of feeding pipes, the specifications of the unloader 5 (unloader speed and the feeding amount per unit time), etc. The time relay KT2 is used to control the time interval between two adjacent feedings. The setting value of the delay time on the time relay KT2 is determined according to the number of feeding times per day, generally more than 3 hours. The contactor KM is used to directly control the start and stop of the drive motor Ma, the reduction motor Mb, and the heating device K.

[0034] like Figure 8As shown, when in use, feed is loaded in the silo 6, first the time relay KTI is set to delay the start of the time relay KT1-1 normally closed contact time to T1 seconds (such as 1-3 seconds), and the time relay KT2 is set to delay the start of the time relay KT2-1 normally closed contact time to T2 seconds. Then close the main switch Q, under the control of the controller, the automatic feeder will automatically feed and stop feeding according to the following steps:

[0035] (1) Cutting:

[0036] Then there is: Figure 8 In the A-A1 branch, the normally closed contact KT2-1 of the time relay KT2 is in the on state, the time relay KT1 is energized, and this branch has been connected.

[0037] The setting time of the time relay KT1 in the A-A1 branch is T1 second, which means that T1 second after the time relay KT1 is energized, the normally closed contact of the time relay KT1-1 will be disconnected, causing the B-B1 branch to lose power.

[0038] At the same time: Figure 8 In the B-B1 branch, relay KA is energized, contactor KM is energized, and the normally closed contact KT1-1 of time relay KT1 is in the on state, and this branch has been connected; at this time, after contactor KM is energized, the normally open main contact KM-1 of control contactor KM is connected, the main circuit is connected, the drive motor Ma is energized and rotates, and the drive motor Ma drives the unloader 5 to start unloading.

[0039] At the same time: Figure 8 In the C-C1 branch, since relay KA is energized, the normally closed contact KA-1 of relay KA becomes open, the branch is not connected, and the time relay KT2 is not energized.

[0040] (2) Stop material:

[0041] T1 seconds after time relay KT1 is energized, the normally closed contact of time relay KT1-1 is disconnected, B-B1 branch is disconnected and de-energized, contactor KM is de-energized, causing the normally open main contact KM-1 of contactor KM to be disconnected, and the drive motor Ma stops rotating after de-energizing. The drive motor Ma rotates for T1 seconds, and the unloader 5 stops running, completing the lowering of the feed. In addition, since the B-B1 branch is disconnected and de-energized, relay KA is also de-energized at the same time, causing the normally closed contact KA-1 of relay KA in the C-C1 branch to close and connect again, and the C-C1 branch is connected and energized, causing time relay KT2 to be energized. The set time of time relay KT2 is T2 seconds, indicating that T2 seconds after time relay KT2 is energized, the normally closed contact of time relay KT2-1 will be disconnected, causing the A-A1 branch to lose power.

[0042] (3) Cycle:

[0043] T2 seconds after the time relay KT2 is energized, the normally closed contact of the time relay KT2-1 is disconnected, the A-A1 branch is disconnected and de-energized, and the time relay KT1 is de-energized, causing the normally closed contact KT1-1 of the time relay KT1 to reset and close again, so that the B-B1 branch is connected, the contactor KM is energized, and the drive motor Ma starts to rotate again. At the same time, the relay KA is also energized, causing the normally closed contact of the relay KA to disconnect again, resulting in the disconnection of the C-C1 branch. The time relay KT2 is de-energized, causing the normally closed contact of the time relay KT2-1 to close again, the A-A1 branch is re-energized, and the time relay KT1 is re-energized and starts timing. Then, steps (1) to (3) are repeated, and the drive motor Ma is started repeatedly in a cycle to realize the timed automatic feeding and timed automatic stopping of feed.

[0044] Embodiment 2:

[0045] The difference between this embodiment and the first embodiment is that:

[0046] like Figure 4-6 As shown, a scattering device is provided in the transition bin. When the amount of feed discharged by the discharger 5 is too large, if it is not scattered, it is easy to concentrate in large quantities at the top of a certain feeding pipe 3, resulting in blockage of the top of the feeding pipe 3, and then making the feeding unsmooth. The existence of the scattering device can effectively disperse the feed particles concentrated in a certain area through the scattering device before entering the feeding pipe 3, which can effectively avoid blocking the feeding pipe 3 and ensure smooth feeding; the scattering device is composed of a plurality of scattering frames 7 and a reduction motor Mb arranged side by side from left to right in the transition bin 4; each scattering frame 7 includes a shaft 71 , side rod 72, transmission gear 74; the shaft rod 71 is rotatably installed in the transition bin 4 through a bearing 75 and its end extends out of the transition bin 4; the side rod 72 is a plurality of rod bodies that are obliquely or vertically fixed on the outer periphery of the shaft rod 71 and rotate with the shaft rod 71; a plurality of auxiliary rods 73 are also provided on the outer periphery of each side rod 72; the transmission gear 74 is fixed to the end of the shaft rod 71 and is located outside the transition bin 4; the reduction motor Mb is installed outside the transition bin 4, and a driving gear that meshes with the transmission gear 74 on one of the shaft rods 71 ​​of the scattering frame 7 is provided on the rotating shaft of the reduction motor Mb.

[0047] When unloading, the reduction motor Mb starts and stops synchronously with the automatic control circuit and the driving motor Ma. When unloading, the driving gear on the rotating shaft of the reduction motor Mb drives the transmission gear 74 of the scattering frame 7 to rotate, thereby causing the scattering frame 7 to rotate as a whole, scattering the material unloaded by the discharger 5, further mixing it, and then dropping it into the unloading pipe 3, and unloading it from the unloading pipe 3 into the material trough 1.

[0048] like Figure 2As shown, the reduction motor Mb is connected to the main circuit of the automatic control circuit through a wire, and is connected in parallel with the drive motor Ma to the other end of the thermal relay FR; the reduction motor Mb and the drive motor Ma are started and stopped synchronously under the control of the automatic control circuit.

[0049] Embodiment three:

[0050] The difference between this embodiment and the second embodiment is that:

[0051] After the feed is unloaded by the discharger 5, although it is scattered by the scattering device and falls into the discharge pipe 3, since the lower pipe opening of the discharge pipe 3 is extended into the feed trough 1, the lower pipe opening of the discharge pipe 3 is close to the bottom of the feed trough 1. When the amount of feed is large and urgent, the feed has not yet been dispersed around the feed trough 1, and the upper end of the feed on the feed trough 1 has already been close to the lower pipe opening of the discharge pipe 3, so that part of the feed remains in the discharge pipe 3. Under the action of gravity, it is accumulated in the discharge pipe 3 to form a blockage. Even if the feed under the discharge pipe 3 is eaten, it is difficult to automatically come down. Therefore, the discharge pipe 3 cannot discharge the feed, the discharge is not smooth, or the discharge is insufficient. In order to overcome this problem, an anti-blocking device is provided in the discharge pipe 3; the anti-blocking device is composed of a plurality of discharge wheels 8 arranged in parallel from top to bottom in the discharge pipe 3; the discharge wheel 8 includes a support shaft 8 1. Sleeve shaft 82, blade 83, driven gear 84; the support shaft 81 is transversely fixed in the discharge tube 3; the sleeve shaft 82 is rotatably sleeved on the support shaft 81 through the bearing 85 and one end thereof extends out of the discharge tube 3; the blade 83 is a plurality of plates installed on the outer periphery of the sleeve shaft 82 and rotates with the sleeve shaft 82 in the discharge tube 3 (in the preferred embodiment, the number of blade 83 plates is three or four and they are evenly installed on the outer periphery of the sleeve shaft 82); the driven gear 84 is located outside the discharge tube 3 and fixed on the end of the sleeve shaft 82 extending out of the discharge tube 3, the driven gears 84 of adjacent discharge wheels 8 are meshed with each other (the diameters of the driven gears 84 of adjacent discharge wheels 8 are not equal), and the driven gear 84 located on the uppermost discharge wheel 8 is meshed with the transmission gear 74 on the scattering device.

[0052] Each plate of the blade 83 is composed of a plurality of rods fixed vertically side by side on the sleeve shaft 82, and the spacing between two adjacent rods on each plate is equal to or greater than the diameter of the rod; the blades 83 on the two adjacent discharge wheels 8 are longitudinally crossed (when the two discharge wheels 8 rotate, the blades 83 can longitudinally cross through the gap between the other rods to save space), and when rotating, the rods on the blades 83 on the two discharge wheels 8 do not contact each other. During the rotation of the discharge wheel 8, the feed that falls on the upper discharge wheel 8 rotates with the discharge wheel 8 and falls into the lower discharge wheel 8, but some feed will still be stuck on the upper discharge wheel 8. Since the blades 83 on the two adjacent discharge wheels 8 are longitudinally crossed, the rod of the lower discharge wheel 8 can scrape off the feed in the gap between the rods of the upper discharge wheel 8 (and can also scrape off the feed in the gap between the rods of the upper discharge wheel 8). Such a setting can avoid blockage inside the discharge pipe 3.

[0053] Since the driven gear 84 of the discharge wheel 8 is meshed with the transmission gear 74 of the scattering device, that is to say, the discharge wheel 8 will start and stop synchronously with the driving motor Ma under the control of the reduction motor Mb and the automatic control circuit.

[0054] Embodiment 4:

[0055] The difference between this embodiment and the third embodiment is that:

[0056] As shown in the figure, an automatic feeder of the present invention also includes a heating device K for automatically heating feed. The purpose of setting the heating device K is that when the temperature is low, the temperature of the feed stored in the silo 6 will decrease, and putting it in the trough 1 will affect the normal feeding of livestock, reduce the livestock's food intake, affect the normal growth of livestock, and even make livestock sick; the heating device K is connected to the main circuit of the automatic control circuit through a wire, and is connected in parallel with the drive motor Ma at the other end of the thermal relay FR; a start switch S is set on the circuit where the heating device K is located. When the temperature is low, press the start switch S to connect the heating device K to the automatic control circuit and automatically start and stop under the control of the automatic control circuit. That is, the heating device K and the drive motor Ma start and stop synchronously under the control of the automatic control circuit.

[0057] Furthermore, an insulating heat-insulating plate is provided on the outer wall of the feed tube 3 to reduce heat loss; the support shaft 81, the sleeve shaft 82, the blade 83, and the driven gear 84 are all made of metal materials and have good thermal conductivity; the support shaft 81 is a hollow tube body with one end open and the other end closed, and the open end of the support shaft 81 is fixed on the inner wall of the feed tube 3 and connected to the outside of the feed tube 3; the heating device K is an electric heating rod 9, and the structure and principle of the electric heating rod 9 are the same as those of the electric heating plate. It uses electric heating alloy wire as the heating material, mica soft board as the insulating material, and is wrapped with a thin metal plate (aluminum plate, stainless steel plate, etc.) for heating. The fixed end of the tail of the electric heating rod 9 is installed on the outer wall of the feed tube 3 corresponding to the support shaft 81, and the head heating end extends into the support shaft 81 from the open end of the support shaft 81. Under the control of the automatic control circuit, each electric heating rod 9 starts and stops automatically. When unloading, the electric heating rod 9 heats the support shaft 81, the sleeve shaft 82, and the blade 83. The feed is heated while passing through the multiple unloading wheels 8 in sequence. When the feed falls into the trough through the bottom of the unloading pipe 3, it has been repeatedly heated. Compared with the conventional static heating method, the heating efficiency is higher and the speed is faster, so that the electric heating rod 9 can start and stop with the unloading process.

[0058] Furthermore, protective covers are provided on both sides of the front and rear of the feeding pipe 3 and the front side of the transition bin 4.
