Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a feeding device. Background Art

[0002] At present, the market has increasingly higher requirements for the quality of glass products, especially high-aluminum glass, high-lithium glass, microcrystalline glass, high-boron glass and other glasses.

[0003] In the glass production process, raw materials are prepared and processed according to the glass production formula to form raw materials for glass production, and then the raw materials are fed into the kiln through the feeding equipment for glass production. The accuracy of the amount of raw materials fed into the kiln has a great influence on the temperature, liquid level, melting and clarification of the glass production in the kiln. Therefore, the feeding equipment needs to accurately control the amount of raw materials fed into the kiln.

[0004] The feeding equipment generally includes a silo and a feeder. The raw materials are accumulated in the silo and slowly transported to the feeder through the discharge port of the silo, and then transported to the kiln by the feeder. The silo is generally provided with an upper feeding position and a lower feeding position. The upper feeding position is the position of the maximum amount of raw materials in the silo, and the lower feeding position is the position of the minimum amount of raw materials in the silo. When the raw materials in the silo reach the upper feeding position, the feeding of raw materials into the silo is stopped, and when the raw materials in the silo are reduced to the lower feeding position, raw materials need to be added to the silo. However, in the prior art, the distance between the upper feeding position and the lower feeding position of the silo is too large, which results in a large change in the pressure of the raw materials on the feeder during the feeding process, thereby causing uneven feeding of the material into the kiln by the feeder, thereby affecting the quality of glass production. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is: how to provide a feeding device that can avoid large changes in the raw material liquid level in the silo and thereby improve the uniformity of feeding into the kiln.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A feeding device comprises a main feeding mechanism, wherein the main feeding mechanism comprises a main material bin and a main feeding assembly, the main material bin is provided with a main upper material position and a main lower material position, the distance between the main upper material position and the main lower material position is 30-100mm, the discharge port of the main material bin is connected with the feed port of the main feeding assembly, and the discharge port of the main feeding assembly is used to communicate with a kiln.

[0008] The working principle of the utility model is: when the main feeding mechanism of the scheme is feeding, the raw materials enter from the feeding port of the main material bin, and then pass through the discharge port of the main material bin and are transported to the kiln through the main feeding assembly. At the same time, in the scheme, a main loading position and a main unloading position are respectively set on the main material bin, and the distance between the main loading position and the main unloading position is set between 30-100mm, so that the distance between the main loading position and the main unloading position is smaller, and the pressure changes of the raw materials in the main material bin at the main loading position on the main feeding assembly and the pressure changes of the raw materials at the main unloading position on the main feeding assembly are also smaller, so that the main feeding assembly can evenly transport the raw materials to the kiln. Therefore, the scheme can avoid large changes in the liquid level of the raw materials in the bin, thereby improving the uniformity of feeding into the kiln.

[0009] Preferably, main sensors are provided at the main loading position and the main unloading position respectively for monitoring the height of the raw materials in the main silo.

[0010] In this way, the main loading position is the highest position of the raw materials in the main material bin, and the main unloading position is the lowest position of the raw materials in the main material bin. By respectively arranging main sensors at the main loading position and the main unloading position, the height of the raw materials in the main material bin can be monitored, so that the raw materials in the main material bin are always between the main loading position and the main unloading position.

[0011] Preferably, the main feeding mechanism further comprises a main weighing device, and the main weighing device is arranged on the outer side wall of the main silo.

[0012] In this way, the main weighing device is used to weigh the raw materials in the main silo to accurately control the amount of raw materials fed into the kiln.

[0013] Preferably, the main feeding assembly includes a main feeding motor and a main screw feeder, the main feeding motor is connected to the main screw feeder so that the main feeding motor can drive the main screw feeder to rotate, and the discharge port of the main silo is connected to the side of the main screw feeder close to the main feeding motor.

[0014] In this way, when the raw materials are conveyed in the main feeding assembly, the main feeding motor drives the main screw feeder to rotate. Under the rotation of the main screw feeder, the raw materials move from one end of the main screw feeder close to the main feeding motor to the other end. During the movement, the main screw feeder continuously stirs the raw materials, thereby making the raw materials further fluffy and the mixing more evenly. After sufficient mixing and stirring, the raw materials are conveyed to the kiln for glass production, which can also effectively improve the production quality of glass in the kiln.

[0015] Preferably, the main screw feeder includes a main screw feeding rod and a main feeding shell, the main screw feeding rod is located in the main feeding shell and connected to the rotating shaft of the main feeding motor, a coolant channel is provided on the side of the main feeding shell close to the kiln, and a coolant inlet and a coolant outlet connected to the coolant channel are also provided on the main feeding shell, the coolant inlet is used to pass the coolant into the coolant channel, and the coolant outlet is used to discharge the coolant in the coolant channel, and the coolant inlet is located on the lower side of the main feeding shell, and the coolant outlet is located on the upper side of the main feeding shell.

[0016] In this way, since the temperature required for producing glass in the kiln is very high, the main screw feeder extending into the kiln also has the problem of high temperature. On the one hand, high temperature will greatly reduce the service life of the main screw feeder. On the other hand, high temperature will easily cause the raw materials in the main screw feeder to melt and block the outlet of the main screw feeder, thereby affecting the transportation of the raw materials. Therefore, this scheme opens a coolant channel on the side of the main feed shell close to the kiln, and transports the coolant from the coolant inlet to the coolant channel, and then discharges it from the coolant outlet, thereby achieving the cooling effect on the main screw feeder. At the same time, this scheme sets the coolant inlet on the lower side of the main feed shell, and sets the coolant outlet on the upper side of the main feed shell, so that when the coolant enters the coolant channel from the coolant inlet, the coolant channel needs to be completely filled before it can be discharged from the coolant outlet, thereby making the coolant channel always full of coolant, thereby ensuring the cooling effect on the main screw feeder.

[0017] Preferably, the feeding equipment also includes an auxiliary feeding mechanism, which includes an auxiliary feeding bin and an auxiliary feeding component, the discharge port of the auxiliary feeding bin is connected to the feed port of the auxiliary feeding component, and the discharge port of the auxiliary feeding component is connected to the feed port of the main bin.

[0018] In this way, by setting up an auxiliary feeding mechanism and utilizing the auxiliary material bin in the auxiliary feeding mechanism to store raw materials, since the distance between the main loading position and the main unloading position of the main material bin is small, the main material bin stores less raw materials. By setting up an auxiliary material bin to store raw materials, frequent feeding at the raw material end can be avoided.

[0019] Preferably, the auxiliary material bin is provided with an auxiliary upper material level and an auxiliary lower material level, and auxiliary sensors are respectively provided at the auxiliary upper material level and the auxiliary lower material level for monitoring the height of the raw materials in the auxiliary material bin.

[0020] In this way, the auxiliary upper material level is the highest position of the raw materials in the auxiliary material bin, and the auxiliary lower material level is the lowest position of the raw materials in the auxiliary material bin. By respectively arranging auxiliary sensors at the auxiliary upper material level and the auxiliary lower material level, the height of the raw materials in the auxiliary material bin can be monitored, so that the raw materials in the auxiliary material bin are always between the auxiliary upper material level and the auxiliary lower material level.

[0021] Preferably, the auxiliary feeding mechanism further includes an auxiliary weighing device, and the auxiliary weighing device is arranged on the outer side wall of the auxiliary material bin.

[0022] In this way, the auxiliary weighing equipment is used to weigh the raw materials in the auxiliary silo to accurately control the amount of raw materials fed into the main silo.

[0023] Preferably, the auxiliary feeding component includes an auxiliary feeding motor and an auxiliary screw feeder, the auxiliary feeding motor is connected to the auxiliary screw feeder so that the auxiliary feeding motor can drive the auxiliary screw feeder to rotate, and the discharge port of the auxiliary material bin is connected to the side of the auxiliary screw feeder close to the auxiliary feeding motor, and the feed port of the main material bin is connected to the side of the auxiliary screw feeder away from the auxiliary feeding motor.

[0024] In this way, when the raw materials are transported from the auxiliary silo to the auxiliary feeding motor, the auxiliary feeding motor drives the auxiliary screw feeder to rotate. Under the rotation of the auxiliary screw feeder, the raw materials move from one end of the auxiliary screw feeder close to the auxiliary feeding motor to the other end. During the movement, the auxiliary screw feeder continuously stirs the raw materials, so that the raw materials are more fluffy and mixed more evenly before entering the main silo.

[0025] Preferably, the discharge port of the auxiliary feeding component is flexibly connected to the feed port of the main silo.

[0026] In this way, the discharge port of the auxiliary feeding assembly and the feed port of the main silo are flexibly connected, thus avoiding a rigid connection between the auxiliary feeding mechanism and the main feeding mechanism, so that the auxiliary weighing device only weighs the auxiliary feeding mechanism, and the main weighing device only weighs the main feeding mechanism, avoiding mutual influence between the auxiliary feeding mechanism and the main feeding mechanism during weighing, and ensuring the accuracy of the weighing data of the auxiliary weighing device and the main weighing device.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0034] During the glass production process, various raw materials need to be processed and mixed according to the glass production formula to form raw materials, and then the raw materials are added into the kiln through a feeding device to produce the glass. Whether the amount of raw materials fed into the kiln by the feeding device is accurate has a great influence on the production quality of the glass. Therefore, this solution provides a feeding device that can accurately control the amount of raw materials entering the kiln.

[0035] As attached Figure 1 To Figure 4 As shown, the feeding equipment of the present scheme includes an auxiliary feeding mechanism 1, a main feeding mechanism 2 and a frame 3, the auxiliary feeding mechanism 1 is installed on the frame 3, the auxiliary feeding mechanism 1 includes an auxiliary feeding bin 101, an auxiliary feeding assembly and an auxiliary weighing device 104, the discharge port of the auxiliary feeding bin 101 is connected with the feed port of the auxiliary feeding assembly, and the auxiliary weighing device 104 is used to weigh the auxiliary feeding mechanism 1 as a whole. The main feeding mechanism 2 includes a main material bin 201, a main feeding assembly and a main weighing device 208. The main material bin 201 is provided with a main loading position 202 and a main unloading position 203. The distance between the main loading position 202 and the main unloading position 203 is 30-100mm. The feeding port of the main material bin 201 is connected with the discharging port of the auxiliary feeding assembly, and the discharging port of the main material bin 201 is connected with the feeding port of the main feeding assembly. The discharging port of the main feeding assembly is used to communicate with the kiln. The main weighing device 208 is used to weigh the main feeding mechanism 2 as a whole.

[0036] When the feeding equipment of the present scheme is in use, the raw materials enter from the feeding port of the auxiliary material bin 101, and the raw materials entering the auxiliary material bin 101 enter the auxiliary feeding component from the discharge port of the auxiliary material bin 101, and then the auxiliary feeding component sends the raw materials into the main material bin 201, and the raw materials entering the main material bin 201 enter the main feeding component through its discharge port, and the main feeding component will eventually be sent into the kiln.

[0037] When the main feeding mechanism transports the raw materials into the kiln, a main loading position 202 and a main unloading position 203 are respectively set on the main silo 201, and the distance between the main loading position 202 and the main unloading position 203 is set between 30-100mm, so that the distance between the main loading position 202 and the main unloading position 203 is smaller, and the pressure changes of the main feeding component caused by the raw materials in the main silo 201 located at the main loading position 202 and the main unloading position 203 are also smaller, so that the main feeding component can evenly transport the raw materials into the kiln. Therefore, this scheme can avoid large changes in the raw material liquid level in the silo, thereby improving the uniformity of feeding into the kiln. At the same time, by setting up an auxiliary feeding mechanism, the auxiliary material bin 101 in the auxiliary feeding mechanism is used to store raw materials. Since the distance between the main loading position 202 and the main unloading position 203 of the main material bin 201 is small, the main material bin 201 stores less raw materials. By setting up the auxiliary material bin 101 to store raw materials, frequent feeding at the raw material end can be avoided.

[0038] In addition, in the process of feeding the raw materials into the kiln, the auxiliary feeding mechanism 1 is used to feed the raw materials into the main feeding mechanism 2, and the auxiliary weighing device 104 is used to weigh the entire auxiliary feeding mechanism 1. The auxiliary weighing device 104 can obtain the weight change value of the auxiliary feeding mechanism 1 per unit time (such as per hour or per minute). The change value is the amount of raw materials delivered by the auxiliary feeding mechanism 1 to the main feeding mechanism 2. Therefore, the auxiliary weighing device 104 can control the amount of raw materials delivered by the auxiliary feeding mechanism 1 to the main feeding mechanism 2 per unit time. The amount of raw materials; similarly, when the main feeding mechanism 2 is conveying the raw materials into the kiln, the main weighing device 208 will weigh the entire main feeding mechanism 2. The main weighing device 208 can be used to obtain the weight change of the main feeding mechanism 2 per unit time. The weight change of the main feeding mechanism 2 combined with the amount of raw materials conveyed to the main feeding mechanism 2 by the auxiliary feeding mechanism 1 can be used to obtain the amount of raw materials conveyed to the kiln by the main feeding mechanism 2. Therefore, the main weighing device 208 can be used to control the amount of raw materials conveyed to the kiln by the main feeding mechanism 2 per unit time. In summary, this scheme designs a two-stage feeding mechanism, and weighs the two-stage feeding mechanism separately. The auxiliary weighing device 104 controls the amount of raw materials delivered by the auxiliary feeding mechanism 1 to the main feeding mechanism 2, so that the amount of raw materials in the main feeding mechanism 2 is already in a relatively precise state. Then, the main weighing device 208 controls the amount of raw materials delivered to the kiln by the main feeding mechanism 2, so as to achieve the purpose of accurately controlling the amount of raw materials fed into the kiln, thereby improving the glass production quality in the kiln.

[0039] As attached Figure 2As shown, in this embodiment, the discharge port of the auxiliary feeding component is flexibly connected to the feed port of the main silo 201. Specifically, the discharge port of the auxiliary feeding component is connected to the feed port of the main silo 201 through a first flexible connector 4, and the first flexible connector 4 can be made of wear-resistant cloth, rubber tube, etc.

[0040] In this way, the discharge port of the auxiliary feeding assembly and the feed port of the main material bin 201 are flexibly connected through the first soft connector 4, thus avoiding the rigid connection between the auxiliary feeding mechanism 1 and the main feeding mechanism 2, so that the auxiliary weighing device 104 only weighs the auxiliary feeding mechanism 1, and the main weighing device 208 only weighs the main feeding mechanism 2, avoiding the mutual influence between the auxiliary feeding mechanism 1 and the main feeding mechanism 2 during weighing, and ensuring the accuracy of the weighing data of the auxiliary weighing device 104 and the main weighing device 2.

[0041] In this embodiment, the auxiliary feeding assembly includes an auxiliary feeding motor 105 and an auxiliary screw feeder 106, and the auxiliary feeding motor 105 is connected to the auxiliary screw feeder 106 so that the auxiliary feeding motor 105 can drive the auxiliary screw feeder 106 to rotate, and the discharge port of the auxiliary material bin 101 is connected to the side of the auxiliary screw feeder 106 close to the auxiliary feeding motor 105;

[0042] The main feeding assembly includes a main feeding motor 204 and a main screw feeder 205. The main feeding motor 204 is connected to the main screw feeder 205 so that the main feeding motor 204 can drive the main screw feeder 205 to rotate, and the feed port of the main material bin 201 is connected to the side of the auxiliary screw feeder 106 away from the auxiliary feeding motor 105, and the discharge port of the main material bin 201 is connected to the side of the main screw feeder 205 close to the main feeding motor 204.

[0043] In this way, when the raw materials are transported from the auxiliary material bin 101 to the auxiliary screw feeder 106, the auxiliary feeding motor 105 drives the auxiliary screw feeder 106 to rotate. Under the rotation of the auxiliary screw feeder 106, the raw materials move from one end of the auxiliary screw feeder 106 close to the auxiliary feeding motor 105 to the other end. During the movement, the auxiliary screw feeder 106 continuously stirs the raw materials, thereby making the raw materials more fluffy and mixed more evenly. When the raw materials enter the main material bin 201 under the action of the auxiliary screw feeder 106, the main material bin 201 further transports the raw materials To the main screw feeder 205, the main feeding motor 204 drives the main screw feeder 205 to rotate. Under the rotation of the main screw feeder 205, the raw materials move from one end of the main screw feeder 205 close to the main feeding motor 204 to the other end. During the movement, the main screw feeder 205 continuously stirs the raw materials, thereby making the raw materials further fluffy and mixed more evenly. After being fully mixed and stirred by the two-stage screw feeder, the raw materials are transported to the kiln for glass production, which can also effectively improve the production quality of glass in the kiln.

[0044] As attached Figure 4 As shown, in this embodiment, the main screw feeder 205 includes a main screw feeding rod 210 and a main feeding shell 211. The main screw feeding rod 210 is located in the main feeding shell 211 and is connected to the rotating shaft of the main feeding motor 204. A coolant channel 212 is provided on the side of the main feeding shell 211 close to the kiln. A coolant inlet 213 and a coolant outlet 214 connected to the coolant channel 212 are also provided on the main feeding shell 211. The coolant inlet 213 is used to pass the coolant into the coolant channel 212, and the coolant outlet 214 is used to discharge the coolant in the coolant channel 212. The coolant inlet 213 is located on the lower side of the main feeding shell 211, and the coolant outlet 214 is located on the upper side of the main feeding shell 211.

[0045] In this way, since the temperature required for producing glass in the kiln is very high, the main screw feeder 205 extended into the kiln also has a high temperature problem. On the one hand, the high temperature will greatly reduce the service life of the main screw feeder 205. On the other hand, the high temperature will easily cause the raw materials in the main screw feeder 205 to melt and block the outlet of the main screw feeder 205, thereby affecting the transportation of the raw materials. Therefore, this scheme opens a coolant channel 212 on the side of the main feeding shell 211 close to the kiln, and transports the coolant from the coolant inlet 213 to the coolant channel 212, and then discharges it from the coolant outlet 214, so as to achieve a cooling effect on the main screw feeder 205. At the same time, in this solution, the coolant inlet 213 is arranged on the lower side of the main feeding shell 211, and the coolant outlet 214 is arranged on the upper side of the main feeding shell 211. In this way, when the coolant enters the coolant channel 212 from the coolant inlet 213, the coolant channel 212 needs to be completely filled before it can be discharged from the coolant outlet 214. In this way, the coolant channel 212 is always filled with coolant, thereby ensuring the cooling effect on the main screw feeder 205.

[0046] In this embodiment, a second flexible connector 206 is provided at the coolant inlet 213 , and a third flexible connector 207 is provided at the coolant outlet 214 .

[0047] In this way, a second flexible connector 206 is provided at the coolant inlet 213, and a third flexible connector 207 is provided at the coolant outlet 214. The flexible connection can avoid the influence of the external cooling water pipeline on the weight of the entire main feeding mechanism 2, thereby ensuring the accuracy of the weighing of the main weighing device 208.

[0048] In this embodiment, the volume of the auxiliary material bin 101 is greater than the volume of the main material bin 201 .

[0049] In this way, the volume of the auxiliary material bin 101 is designed to be larger than the volume of the main material bin 201. The larger volume of the auxiliary material bin 101 can store more raw materials in the auxiliary material bin 101, while the smaller volume of the main material bin 201 can accommodate less raw materials in the main material bin 201. In this way, a small change in the weight value of the raw materials in the main material bin 201 can also cause a change in the data of the main weighing device 208, thereby achieving more accurate measurement of the raw materials in the main material bin 201.

[0050] In this embodiment, the main feeding mechanism 2 further includes a supporting movable frame 209 , the main feeding assembly is arranged on the supporting movable frame 209 , and a roller 216 is further arranged on the supporting movable frame 209 to drive the supporting movable frame 209 to move through the roller 216 .

[0051] In this way, by setting up the supporting movable frame 209, when the main feeding mechanism 2 needs to be inspected and repaired after being used for a period of time, the first soft connection part 4 between the auxiliary feeding mechanism 1 and the main feeding mechanism 2 is removed, and then the supporting movable frame 209 is driven to move by the roller 216, and the supporting movable frame 209 then drives the entire main feeding mechanism 2 to move, so as to facilitate the inspection and repair of the main feeding mechanism 2.

[0052] In this embodiment, the auxiliary weighing device 104 is disposed on the outer side wall of the auxiliary material bin 101 , and the main weighing device 208 is disposed on the lower side of the supporting movable frame 209 .

[0053] In this way, the auxiliary weighing device 104 is arranged on the outer wall of the auxiliary material bin 101. Since the auxiliary feeding mechanism 1 and the main feeding mechanism 2 are connected by the first flexible connector 4, the auxiliary feeding mechanism 1 as a whole is equivalent to being in a suspended state. The auxiliary weighing device 104 is arranged on the outer wall of the auxiliary material bin 101, so that the entire auxiliary feeding mechanism 1 can be weighed. In the auxiliary feeding mechanism 1, except for the weight of the raw materials in the auxiliary material bin 101, the weight of other materials will not change. Therefore, by weighing the entire auxiliary feeding mechanism 1, the change of the amount of raw materials in the auxiliary material bin 101 can be obtained; and for the main feeding mechanism 2, if the main weighing device 208 is arranged on the main material bin 201, it is necessary to A soft connection is also made between the main silo 201 and the main screw feeder 205. However, on the one hand, this soft connection will affect the transportation of raw materials between the main silo 201 and the main screw feeder 205. On the other hand, after the raw materials enter from the feed port of the main silo 201, they move downward under the action of gravity and are directly output from the discharge port to the main screw feeder 205. This will make it impossible for the main weighing device 208 to accurately sense the changes in the amount of raw materials in the main silo 201. Therefore, this scheme sets the main weighing device 208 on the lower side of the supporting movable frame 209, so that the main weighing device 208 obtains the weight of the entire main feeding mechanism 2, avoiding the above problems on the right side, and can achieve accurate measurement of the raw materials.

[0054] In this embodiment, a secondary material loading position 102 and a secondary material unloading position 103 are provided on the secondary material bin 101. The secondary material loading position 102 is the highest position of the raw materials in the secondary material bin 101, and the secondary material unloading position 103 is the lowest position of the raw materials in the secondary material bin 101. When used, the secondary material loading position 102 is generally located at 1 / 3 of the height direction of the secondary material bin 101 close to the upper side, and the secondary material unloading position 103 is generally located at 1 / 4 of the height direction of the secondary material bin 101 close to the lower side.

[0055] The main loading position 202 is the highest position of the raw materials in the main material bin 201, and the main unloading position 203 is the lowest position of the raw materials in the main material bin 201. When in use, the main loading position 202 is generally located at 1 / 3 of the height of the main material bin 201 close to the upper side, and the main unloading position 203 is generally located at 1 / 4 of the height of the main material bin 201 close to the lower side.

[0056] In this way, by setting the loading position and the unloading position, the amount of raw materials in the auxiliary bin 101 and the main bin 201 can be controlled to avoid excessive or insufficient raw materials in the auxiliary bin 101 and the main bin 201. When the raw materials in the auxiliary bin 101 reach the auxiliary loading position 102, the external feeding device stops feeding into the auxiliary bin 101, and when the raw materials in the auxiliary bin 101 reach the auxiliary unloading position 103, the external feeding device starts feeding into the auxiliary bin 101; when the raw materials in the main bin 201 reach the main loading position 202, the auxiliary feeding mechanism 1 stops feeding into the main bin 201, and when the raw materials in the main bin 201 reach the main unloading position 203, the auxiliary feeding mechanism 1 starts feeding into the main bin 201. During specific use, main sensors are respectively provided at the main loading position 202 and the main unloading position 203 for monitoring the height of the raw materials in the main silo 201, and auxiliary loading position 102 and auxiliary unloading position 103 are provided on the auxiliary silo 101. Auxiliary sensors are respectively provided at the auxiliary loading position 102 and the auxiliary unloading position 103 for monitoring the height of the raw materials in the auxiliary silo 101. During specific use, contact switches, photoelectric sensors and other devices can also be used to trigger corresponding control signals when the raw materials reach the corresponding position to achieve the above effects.

[0057] In this embodiment, the main feeding motor 204 and the main screw feeder 205 are connected via a chain transmission assembly 215, which includes a driving wheel, a driven wheel, and a transmission chain mounted on the driving wheel and the driven wheel. The driving wheel is connected to the main feeding motor 204, and the driven wheel is connected to the main screw feeder 205.

[0058] In this way, when the main feeding motor 204 rotates, it drives the driving wheel to rotate, and the driving wheel then drives the driven wheel to rotate through the transmission chain, and the driven wheel further drives the main spiral feeder 205 to rotate. The chain transmission mode is not easy to slip, and the performance is more stable and reliable.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
