Description

Technical Field

[0001] The invention belongs to the field of feed production, in particular to automatic feed production equipment. Background Art

[0002] Feed is the general term for food for animals raised by humans. Generally, feed mainly refers to the food for animals raised in agriculture or animal husbandry. In order to ensure that the feed has sufficient nutrition, current feed generally requires a mixture of multiple raw materials.

[0003] To make raw materials, it is generally necessary to clean the raw materials first, and then mix the various raw materials in a certain proportion according to a certain formula to meet the nutritional needs of different livestock and poultry. Then, the various raw materials are mixed according to the formula requirements to make the various nutrients evenly distributed. Finally, the mixed feed powder is made into granules through a pellet machine to improve the utilization rate of the feed.

[0004] In the traditional feed production process, in order to ensure the correct ratio of various contents in the feed, various raw materials need to be weighed first, and then the weighed raw materials need to be mixed and stirred to finally make the feed. However, during the weighing process, an appropriate amount of raw materials need to be injected into the weighing device first, and then transferred after the weighing is completed. Even when producing the same batch of products, it is necessary to continuously weigh the required weight of raw materials, which makes the entire production process time-consuming.

[0005] To this end, the present invention provides an automatic feed production device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: the automatic feed production equipment described in the present invention comprises a mixing drum for mixing various raw materials, a plurality of raw material drums for containing raw materials are arranged on the outside of the mixing drum, a weighing tank is arranged at the bottom of the raw material drum, a plurality of vertically arranged tension measuring instruments are fixedly connected between the outside of the weighing tank and the outside of the raw material drum, a material transfer pipe capable of sucking raw materials is arranged between the raw material drum and the weighing tank, a connecting pipe is arranged between the weighing tank and the mixing drum, a negative pressure pump connected to the inside of the mixing drum is installed on the outside of the mixing drum, and a plurality of discharge valves are installed at the bottom of the mixing drum;

[0008] Preferably, through the arrangement of a material transfer pipe and a connecting pipe, various required raw materials are placed in different raw material barrels, and the raw materials in the raw material barrel are transported to the weighing tank by suction using the material transfer pipe. The weight change of the weighing tank is detected by a tension measuring instrument to know the weight of the raw materials. Then the negative pressure pump generates negative pressure in the mixing barrel, and the negative pressure draws the weighed raw materials in the weighing tank into the mixing barrel through the connecting pipe for crushing and mixing, and finally the finished product is discharged through the discharge valve. When making the same batch of feed, it is only necessary to ensure the weight of the raw materials sucked by the material transfer pipe for the first time. In the subsequent production process, it is only necessary to use the same power and time to suck the raw materials in the raw material barrel, so as to ensure that the raw materials in the weighing tank are almost the same as the first time, which can save a lot of weighing time. In this case, the transfer of raw materials from the raw material barrel to the weighing tank can be carried out simultaneously with the transfer of raw materials from the weighing tank to the mixing barrel, which can save a lot of time, thereby effectively improving the production efficiency of the feed.

[0009] Preferably, a material pump 1 is installed in the middle of the material transfer tube, a recovery tube is provided between the raw material barrel and the weighing tank, and a material pump 2 is installed in the middle of the recovery tube. The material pump 1 generates negative pressure at one end of the material transfer tube to transfer the raw material in the raw material barrel to the weighing tank. With the setting of the recovery tube, when the raw material transfer and weighing are performed for the first time, the tension measuring instrument will always measure the amount of raw material in the weighing tank. When the measured weight reaches the standard, the material pump 1 is stopped. However, due to the influence of factors such as the vibration of the electrical appliance and the residue in the pipeline, it is easy to cause the final amount of raw material to be greater than the required amount. At this time, by starting the second extraction pump, negative pressure is generated at the bottom of the recovery pipe, and the excess raw material is drawn back into the raw material barrel to ensure the accurate amount of raw material. When extracting raw materials for the second time, shorten the extraction time appropriately, and read the value of the tension measuring instrument after all electrical appliances are stopped. After several times, the accurate extraction time can be obtained. Subsequently, the extraction pump 1 is kept at the current extraction time, and the appropriate amount of raw material can be extracted more accurately. It should be noted that the amount of raw material in the raw material barrel needs to cover the end of the transfer pipe to reduce the influence of cavity extraction on the extraction amount.

[0010] Preferably, the bottom of the raw material barrel is open, the top of the weighing tank is open, the outer side of the top of the weighing tank is slidably engaged with the bottom of the raw material barrel, a partition plate is fixedly connected to the bottom of the raw material barrel, the extraction pump 1 and the extraction pump 2 are both fixedly connected to the partition plate, a plurality of support arms are fixedly connected to the outer side of the raw material barrel, a sealing cover is provided on the top of the raw material barrel, the tops of the material transfer pipe and the recovery pipe are both located above the partition plate, the bottoms of the material transfer pipe and the recovery pipe are both located below the partition plate, the raw material barrel is suspended and installed by the support arms, and the entire weighing tank is suspended and fixed by a plurality of tension measuring instruments. At this time, the tension measuring instrument can measure the weight of the bottom weighing tank, and the weight of the raw material can be obtained by subtracting the weight of the weighing tank itself. The top of the partition plate is used to hold the raw material, and the sealing cover is used to reduce the influence of the external environment.

[0011] Preferably, the top surface of the partition plate is inclined, and one side of the partition plate is split into two plates, there is a cavity between the two plates, the extraction pump 1 and the extraction pump 2 are both located in the cavity, the inclined setting of the top surface of the partition plate can allow the accumulated raw materials to move to the middle, reducing the problem of raw material vacancies in the middle, the cavity is used to place the extraction pump 1 and the extraction pump 2, reducing the impact of the raw materials on the electrical appliances, and also reducing the problem of difficulty in heat dissipation of the electrical appliances due to the accumulation of raw materials.

[0012] Preferably, an absorption tube is fixedly connected to the inner wall of the weighing tank, the bottom of the absorption tube is located in the middle of the bottom surface of the weighing tank, and a drawing tube is fixedly connected to the outer side of the partition plate, the drawing tube passes through the raw material cylinder and is connected to the connecting tube, and the drawing tube and the top of the absorption tube are connected by a retractable elastic tube, the absorption tube and the weighing tank are fixed, which is counted as the initial weight of the weighing tank, and the negative pressure of the connecting tube passes through the drawing tube, and the drawing tube transfers the negative pressure to the absorption tube for raw material transfer. Because the weighing tank will sink to a certain extent during the process of injecting the raw material into the weighing tank, the elastic tube can be appropriately stretched to adapt to the changes of the weighing tank. The elastic tube can only be stretched vertically and will not be flattened under the action of negative pressure, thereby ensuring the normal transfer of the raw material.

[0013] Preferably, the top of the material transfer tube is arranged in an arc-shaped outer arch shape, and the arched part is located in the raw material barrel, and the bottom of the absorption tube is arranged in a diffuse opening shape. The pumping pump will generate vibration, and the vibration is transmitted to the top of the material transfer tube, which can shake out the raw materials in the raw material barrel and assist in the suction of the raw materials. The setting of the bottom of the absorption tube can absorb the raw materials at the bottom of the weighing tank at multiple angles, and one side of the absorption tube is in contact with the inner wall of the weighing tank. The raw materials will accumulate to the bottom under the action of gravity, thus ensuring that the absorption tube absorbs and transfers all the raw materials.

[0014] Preferably, a plurality of transmission valves adapted to the connecting pipe are fixedly connected to the top of the mixing barrel, and the negative pressure pump is arranged on one side of the top of the mixing barrel. The transmission valve is controlled by electromagnetics. When the negative pressure pump generates negative pressure inside the mixing barrel, the required transmission valve is opened to transfer the negative pressure to the designated absorption tube to complete the transfer of the raw materials. Under this setting, only one negative pressure device is needed to realize the secondary transfer function of the raw materials inside multiple weighing tanks. The stacking height of the raw materials in the mixing barrel will not exceed that of the negative pressure pump. The absorption end of the negative pressure pump is also provided with a partition net. The raw materials are in granular form before being injected into the mixing barrel and will not be absorbed by the negative pressure pump. At the same time, the airflow generated by the suction of the negative pressure pump can also carry away dust and fine particles on the surface of the raw materials to ensure the quality of the raw materials.

[0015] Preferably, a horizontally arranged stirring rod is installed in the middle of the inner side of the mixing barrel, and two groups of stirring blades are installed on the outer side of the stirring rod. A driving motor for driving the stirring rod to rotate is installed on the outer side of the mixing barrel. The stirring rod is controlled to rotate by the driving motor, and the stirring rod and the stirring blades are driven to rotate. The stirring blades have sharp edges and can effectively crush the raw materials. At the same time, during the rotation of the stirring blades, multiple raw materials can be mixed, thereby completing the crushing and mixing functions of the raw materials.

[0016] Preferably, the two groups of stirring blades are arranged in an arc shape, and the two groups of stirring blades are distributed on the surface of the stirring rod, one on the left and the other on the right. The bending directions of the two groups of stirring blades are opposite. The two groups of stirring blades are one on the left and the other on the right. During the rotation, the stirring blade on the left will transport the raw materials to the central area due to its own arc setting. The stirring blade on the right will also transport the raw materials to the central area during rotation due to its opposite bending direction. When too much raw material is accumulated in the central area, the raw material will be squeezed out from the gap between the stirring blades and then move to both sides. Through this arrangement, not only the raw materials are effectively mixed, but the raw materials move everywhere in the mixing barrel, which also increases the effect of being fully crushed.

[0017] Preferably, both ends of the mixing drum are fixedly connected to support frames, the driving motor is fixedly connected to the outside of the support frames, and the multiple discharge valves are distributed in the middle of the bottom surface of the mixing drum. The support frames prop up the mixing drum upward so that the discharge valve can be installed on the bottom. The two sets of stirring blades can concentrate the raw materials to the center, and the finished products can be accumulated above the discharge valve during the discharge stage to assist the discharge process.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The automatic feed production equipment described in the present invention puts various required raw materials into different raw material barrels through the arrangement of a feeding pipe and a connecting pipe, and uses the feeding pipe to transport the raw materials in the raw material barrel to the weighing tank by suction. The weight change of the weighing tank is detected by a tension measuring instrument to know the weight of the raw materials. Then the negative pressure pump generates negative pressure in the mixing barrel, and the negative pressure draws the weighed raw materials in the weighing tank into the mixing barrel through the connecting pipe for crushing and mixing, and finally the finished product is discharged through the discharge valve. When making the same batch of feed, it is only necessary to ensure the weight of the raw materials sucked by the feeding pipe for the first time. In the subsequent production process, it is only necessary to use the same power and time to suck the raw materials in the raw material barrel, so as to ensure that the raw materials in the weighing tank are almost the same as the first time, so that a lot of weighing time can be saved. In this case, the transfer of raw materials from the raw material barrel to the weighing tank can be carried out simultaneously with the transfer of raw materials from the weighing tank to the mixing barrel, which can save a lot of time, thereby effectively improving the production efficiency of feed.

[0020] 2. The automatic feed production equipment described in the present invention generates negative pressure at one end of the material transfer pipe through the first feed pump to transfer the raw materials in the raw material barrel to the weighing tank. The recovery pipe is set. When the raw material transfer and weighing are carried out for the first time, the tension measuring instrument will always measure the amount of raw materials in the weighing tank. When the measured weight meets the standard, the feed pump is stopped. However, due to the influencing factors such as the vibration of the electrical appliance and the residue in the pipeline, it is easy to cause the final amount of raw materials to be greater than the required amount. At this time, by starting the feed pump, a negative pressure is generated at the bottom of the recovery pipe to draw the excess raw material back into the raw material barrel to ensure the accurate amount of raw materials. When the raw materials are extracted for the second time, the extraction time is appropriately shortened, and the value of the tension measuring instrument is read after all electrical appliances are stopped. After several times, the accurate extraction time can be obtained. Subsequently, the feed pump is kept at the extraction time at this time to accurately extract an appropriate amount of raw materials. It should be noted that the amount of raw materials in the raw material barrel needs to cover the end of the material transfer pipe to reduce the influence of cavity extraction on the extraction amount.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 7 As shown, an automatic feed production device according to an embodiment of the present invention comprises a mixing drum 1 for mixing various raw materials, a plurality of raw material drums 2 for containing raw materials are arranged on the outside of the mixing drum 1, a weighing tank 12 is arranged at the bottom of the raw material drum 2, a plurality of vertically arranged tension measuring instruments 13 are fixedly connected between the outside of the weighing tank 12 and the outside of the raw material drum 2, a material transfer pipe 15 capable of sucking raw materials is arranged between the raw material drum 2 and the weighing tank 12, a connecting pipe 4 is arranged between the weighing tank 12 and the mixing drum 1, a negative pressure pump 5 connected to the inside of the mixing drum 1 is installed on the outside of the mixing drum 1, and a plurality of discharge valves 6 are installed at the bottom of the mixing drum 1;

[0032] Through the arrangement of the material transfer pipe 15 and the connecting pipe 4, various required raw materials are placed in different raw material barrels 2, and the material transfer pipe 15 is used to transport the raw materials in the raw material barrel 2 to the weighing tank 12 by suction. The weight change of the weighing tank 12 is detected by the tension measuring instrument 13, so as to know the weight of the raw materials. Then, the negative pressure pump 5 generates negative pressure in the mixing barrel 1, and the negative pressure draws the weighed raw materials in the weighing tank 12 into the mixing barrel 1 through the connecting pipe 4 for crushing and mixing. Finally, the finished product is discharged through the discharge valve 6, and the finished product enters the granulator for Granulation is sufficient. When making the same batch of feed, it is only necessary to ensure the weight of the raw materials sucked by the first feeding pipe 15. In the subsequent production process, it is only necessary to use the same power and time to suck the raw materials in the raw material barrel 2 to ensure that the raw materials in the weighing tank 12 are almost the same as the first time. This can save a lot of weighing time. In this case, the transfer of raw materials from the raw material barrel 2 to the weighing tank 12 can be carried out simultaneously with the transfer of raw materials from the weighing tank 12 to the mixing barrel 1, which can save a lot of time and effectively improve the production efficiency of the feed.

[0033] A material pump 16 is installed in the middle of the material transfer pipe 15, a recovery pipe 18 is provided between the raw material barrel 2 and the weighing tank 12, and a material pump 2 19 is installed in the middle of the recovery pipe 18;

[0034] During operation, negative pressure is generated at one end of the material transfer tube 15 through the material extraction pump 16 to transfer the raw materials in the raw material barrel 2 to the weighing tank 12. The recovery tube 18 is set. When the raw materials are transferred and weighed for the first time, the tension measuring instrument 13 will always measure the amount of raw materials in the weighing tank 12. When the measured weight meets the standard, the material extraction pump 16 is stopped. However, due to factors such as vibration of the electrical appliances and residue in the pipeline, the final amount of raw materials may be greater than the required amount. At this time, the material extraction pump 19 is started to generate negative pressure at the bottom of the recovery tube 18 to draw the excess raw materials back into the raw material barrel 2 to ensure the accurate amount of raw materials. When the raw materials are extracted for the second time, the extraction time is appropriately shortened, and the value of the tension measuring instrument 13 is read after all electrical appliances are stopped. After several times, the accurate extraction time can be obtained. Subsequently, the material extraction pump 16 is kept at the extraction time at this time to accurately extract the appropriate amount of raw materials. It should be noted that the amount of raw materials in the raw material barrel 2 needs to cover the end of the material transfer tube 15 to reduce the influence of cavity extraction on the extraction amount.

[0035] The bottom of the raw material barrel 2 is open, the top of the weighing tank 12 is open, the outer side of the top of the weighing tank 12 is slidably engaged with the bottom of the raw material barrel 2, a partition plate 14 is fixedly connected to the bottom of the raw material barrel 2, the first pump 16 and the second pump 19 are both fixedly connected to the partition plate 14, a plurality of support arms 10 are fixedly connected to the outer side of the raw material barrel 2, a sealing cover 9 is provided on the top of the raw material barrel 2, the tops of the material transfer pipe 15 and the recovery pipe 18 are both located above the partition plate 14, and the bottoms of the material transfer pipe 15 and the recovery pipe 18 are both located below the partition plate 14;

[0036] During operation, the raw material barrel 2 is suspended and installed by the support arm 10, and the entire weighing tank 12 is suspended and fixed by multiple tension measuring instruments 13. At this time, the tension measuring instrument 13 can measure the weight of the bottom weighing tank 12. By subtracting the weight of the weighing tank 12 itself, the weight of the raw material can be obtained. The partition plate 14 is used to hold the raw materials, and the sealing cover 9 is used to reduce the influence of the external environment.

[0037] The top surface of the partition plate 14 is inclined, and one side of the partition plate 14 is split into two plates, and there is a cavity between the two plates, and the material pump 1 16 and the material pump 2 19 are both located in the cavity;

[0038] During operation, the inclined setting of the top surface of the partition plate 14 can allow the accumulated raw materials to move to the middle, reducing the problem of raw material shortage in the middle. The cavity is used to place the extraction pump 16 and the extraction pump 2 19, reducing the impact of the raw materials on the electrical appliances and reducing the problem of difficulty in heat dissipation of the electrical appliances due to the accumulation of raw materials.

[0039] An absorption tube 17 is fixedly connected to the inner wall of the weighing tank 12, and the bottom of the absorption tube 17 is located in the middle of the bottom surface of the weighing tank 12. A material extraction tube 11 is fixedly connected to the outer side of the partition plate 14, and the material extraction tube 11 passes through the raw material cylinder 2 and is connected to the connecting tube 4. The material extraction tube 11 is connected to the top of the absorption tube 17 through a retractable elastic tube.

[0040] During operation, the absorption tube 17 is fixed to the weighing tank 12, which is counted as the initial weight of the weighing tank 12. The negative pressure of the connecting tube 4 passes through the extraction tube 11, and the extraction tube 11 transmits the negative pressure to the absorption tube 17 for raw material transfer. Because the weighing tank 12 will sink to a certain extent during the process of injecting the raw materials into the weighing tank 12, the elastic tube can be appropriately stretched to adapt to the changes of the weighing tank 12. The elastic tube can only be stretched vertically and will not be flattened under the action of negative pressure, thereby ensuring the normal transfer of raw materials.

[0041] The top of the material transfer pipe 15 is arranged in an arc-shaped outer arch shape, and the arched part is located in the raw material barrel 2, and the bottom of the absorption pipe 17 is arranged in a diffuse opening shape;

[0042] When working, the extraction pump 16 will generate vibration, and the vibration is transmitted to the top of the material transfer pipe 15, which can shake the raw materials in the raw material barrel 2 and assist the suction of the raw materials. The setting of the bottom of the absorption tube 17 can absorb the raw materials at the bottom of the weighing tank 12 at multiple angles, and one side of the absorption tube 17 is in contact with the inner wall of the weighing tank 12. The raw materials will accumulate to the bottom under the action of gravity, thus ensuring that the absorption tube 17 absorbs and transfers all the raw materials.

[0043] A plurality of transmission valves 3 adapted to the connecting pipe 4 are fixedly connected to the top of the mixing cylinder 1, and the negative pressure pump 5 is arranged on one side of the top of the mixing cylinder 1;

[0044] During operation, the transmission valve 3 is controlled by electromagnetic means. After the negative pressure pump 5 generates negative pressure inside the mixing barrel 1, the required transmission valve 3 is opened to transfer the negative pressure to the designated absorption tube 17 to complete the transfer of the raw materials. Under this setting, only one negative pressure device is needed to realize the secondary transfer function of the raw materials inside multiple weighing tanks 12. The stacking height of the raw materials in the mixing barrel 1 will not exceed that of the negative pressure pump 5. A partition net is also provided at the absorption end of the negative pressure pump 5. The raw materials are in granular form before being injected into the mixing barrel 1 and will not be absorbed by the negative pressure pump 5. At the same time, the airflow generated by the suction of the negative pressure pump 5 can also carry away dust and fine particles on the surface of the raw materials to ensure the quality of the raw materials.

[0045] A horizontally arranged stirring rod 20 is installed in the middle of the inner side of the mixing barrel 1, two groups of stirring blades 21 are installed on the outer side of the stirring rod 20, and a driving motor 8 for driving the stirring rod 20 to rotate is installed on the outer side of the mixing barrel 1;

[0046] During operation, the stirring rod 20 is controlled to rotate by driving the motor 8, which drives the stirring rod 20 and the stirring blade 21 to rotate. The stirring blade 21 has a sharp edge and can effectively crush the raw materials. At the same time, during the rotation of the stirring blade 21, multiple raw materials can be mixed, thereby completing the crushing and mixing functions of the raw materials.

[0047] The two groups of stirring blades 21 are both arranged in an arc shape, and the two groups of stirring blades 21 are distributed on the surface of the stirring rod 20, one on the left and one on the right, and the bending directions of the two groups of stirring blades 21 are opposite;

[0048] During operation, the two groups of stirring blades 21 are arranged on the left and the right. The stirring blade 21 on the left will transport the raw materials to the central area due to its own arc-shaped setting during rotation. The stirring blade 21 on the right will also transport the raw materials to the central area during rotation due to its opposite bending direction. When too much raw material is accumulated in the central area, the raw material will be squeezed outward from the gap of the stirring blade 21 and then move to both sides. Through this setting, not only the raw materials are effectively mixed, but the raw materials also move everywhere in the mixing barrel 1, which also increases the effect of being fully crushed.

[0049] Both ends of the mixing drum 1 are fixedly connected with support frames 7, the driving motor 8 is fixedly connected to the outside of the support frame 7, and the plurality of discharge valves 6 are distributed in the middle of the bottom surface of the mixing drum 1;

[0050] During operation, the support frame 7 props up the mixing drum 1 so that the discharge valve 6 can be installed at the bottom. The two sets of stirring blades 21 can concentrate the raw materials to the center. During the discharge stage, the finished products can be accumulated above the discharge valve 6 to assist the discharge process.

[0051] During operation, various required raw materials are put into different raw material barrels 2 through the setting of the material transfer pipe 15 and the connecting pipe 4, and the raw materials in the raw material barrel 2 are transported to the weighing tank 12 by suction using the material transfer pipe 15. The weight change of the weighing tank 12 is detected by the tension measuring instrument 13, so as to know the weight of the raw materials. Then, the negative pressure pump 5 generates negative pressure in the mixing barrel 1, and the negative pressure draws the weighed raw materials in the weighing tank 12 into the mixing barrel 1 through the connecting pipe 4 for crushing and mixing, and finally the finished product is discharged through the discharge valve 6. When making the same batch of feed, it is only necessary to ensure the weight of the raw materials sucked by the material transfer pipe 15 for the first time. In the subsequent production process, it is only necessary to use the same power and time to suck the raw materials in the raw material barrel 2, so as to ensure that the raw materials in the weighing tank 12 are almost the same as the first time, so that a lot of weighing time can be saved. In this case, the transfer of raw materials from the raw material barrel 2 to the weighing tank 12 can be carried out synchronously with the transfer of raw materials from the weighing tank 12 to the mixing barrel 1, which can save a lot of time, thereby effectively improving the production efficiency of feed;

[0052] The material pump 16 is used to generate negative pressure at one end of the material transfer tube 15, and the raw materials in the raw material barrel 2 are transferred to the weighing tank 12. The setting of the recovery tube 18 means that when the raw material is transferred and weighed for the first time, the tension measuring instrument 13 will always measure the amount of raw materials in the weighing tank 12. When the measured weight reaches the standard, the material pump 16 is stopped. However, due to the influence factors such as the vibration of the electrical appliances and the residue of the pipeline, it is easy to cause the final amount of raw materials to be greater than the required amount. At this time, the material pump 19 is started to generate negative pressure at the bottom of the recovery tube 18, and the excess amount of raw materials is drawn back into the raw material barrel 2 to ensure the accurate amount of raw materials. When the raw materials are extracted for the second time, the extraction time is appropriately shortened, and the value of the tension measuring instrument 13 is read after all electrical appliances are stopped. After several times, the accurate extraction time can be obtained. Subsequently, the material pump 16 is kept at the extraction time at this time, so that the appropriate amount of raw materials can be extracted more accurately. It should be noted that the amount of raw materials in the raw material barrel 2 needs to cover the end of the material transfer tube 15 to reduce the influence of cavity extraction on the extraction amount.

[0053] The raw material barrel 2 is suspended and installed by the support arm 10, and the entire weighing tank 12 is suspended and fixed by multiple tension measuring instruments 13. At this time, the tension measuring instrument 13 can measure the weight of the bottom weighing tank 12. Subtracting the weight of the weighing tank 12 itself, the weight of the raw material can be obtained. The upper part of the partition plate 14 is used to hold the raw material, and the sealing cover 9 is used to reduce the influence of the external environment;

[0054] The inclined setting of the top surface of the partition plate 14 allows the accumulated raw materials to move to the middle, reducing the problem of raw material vacancies in the middle. The cavity is used to place the first pump 16 and the second pump 19, reducing the impact of the raw materials on the electrical appliances and also reducing the problem of difficulty in heat dissipation of the electrical appliances due to the accumulation of raw materials.

[0055] The absorption tube 17 is fixed to the weighing tank 12, which is counted as the initial weight of the weighing tank 12. The negative pressure of the connecting tube 4 passes through the material extraction tube 11, and the material extraction tube 11 then transmits the negative pressure to the absorption tube 17 for raw material transfer. Because the weighing tank 12 will sink to a certain extent during the process of injecting the raw material into the weighing tank 12, the elastic tube can be appropriately stretched to adapt to the change of the weighing tank 12. The elastic tube can only be stretched vertically and will not be flattened under the negative pressure, so as to ensure the normal transfer of the raw material;

[0056] When the material pump 16 is working, it will generate vibration, which is transmitted to the top of the material transfer pipe 15, which can shake the raw materials in the raw material barrel 2 and assist the suction of the raw materials. The setting of the bottom of the absorption pipe 17 can absorb the raw materials at the bottom of the weighing tank 12 at multiple angles, and one side of the absorption pipe 17 is in contact with the inner wall of the weighing tank 12. The raw materials will accumulate to the bottom under the action of gravity, so that it can be ensured that the absorption pipe 17 absorbs and transfers all the raw materials;

[0057] The transfer valve 3 is controlled by electromagnetics. When the negative pressure pump 5 generates negative pressure inside the mixing barrel 1, the required transfer valve 3 is opened to transfer the negative pressure to the designated absorption tube 17 to complete the transfer of the raw materials. Under this setting, only one negative pressure device is needed to realize the secondary transfer function of the raw materials inside multiple weighing tanks 12. The stacking height of the raw materials in the mixing barrel 1 will not exceed the negative pressure pump 5. The absorption end of the negative pressure pump 5 is also provided with a partition net. The raw materials are in granular form before being injected into the mixing barrel 1 and will not be absorbed by the negative pressure pump 5. At the same time, the airflow generated by the suction of the negative pressure pump 5 can also carry away dust and fine particles on the surface of the raw materials to ensure the quality of the raw materials.

[0058] The stirring rod 20 is controlled to rotate by the driving motor 8, which drives the stirring rod 20 and the stirring blade 21 to rotate. The stirring blade 21 has a sharp edge and can effectively crush the raw materials. At the same time, during the rotation of the stirring blade 21, multiple raw materials can be mixed, thereby completing the crushing and mixing functions of the raw materials;

[0059] The two groups of stirring blades 21 are arranged on the left and the right. The stirring blades 21 on the left convey the raw materials to the central area due to their own arc-shaped setting during the rotation process. The stirring blades 21 on the right convey the raw materials to the central area during the rotation due to their opposite bending direction. When too much raw materials are accumulated in the central area, the raw materials will be squeezed outward from the gaps of the stirring blades 21 and then move to both sides. Through this arrangement, not only the raw materials are effectively mixed, but also the raw materials move everywhere in the mixing barrel 1, which also increases the effect of being fully crushed.

[0060] The support frame 7 props up the mixing drum 1 so that the discharge valve 6 can be installed at the bottom. The two sets of stirring blades 21 can concentrate the raw materials to the center. During the discharge stage, the finished products can be accumulated above the discharge valve 6 to assist the discharge process.
