Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, and more specifically to a medicine mixing device with a scraper. Background Art

[0002] In a farm, the treatment of pig diseases is done by the breeders in the unit. Usually, some diseases require the addition of multiple drugs at the same time to treat the pigs in the unit to achieve a better treatment effect. However, some breeders lack practical experience and professional knowledge of medication, and cannot strictly follow the dosage when using drugs. In addition, the existing drug mixing method is mostly manual mixing, so the drugs are not mixed evenly and the treatment effect is poor. To solve this problem, there is a drug mixing device with an internal structure such as Figure 1 As shown, Figure 1 Schematic diagram of the internal structure of an existing medicine mixing device, which includes a stirring drive component 101, a stirring rod 102, a spiral central blade 103, a spiral ribbon 104, a scraper support rod 105, a scraper 106, a conical tip scraper 107, an end scraper 108 and a coupling 109. It can be seen that in this scheme, multiple scraper support rods 105 are respectively welded to the stirring rod 102, and a scraper 106 is fixed at the end of each scraper support rod 105. The end of each scraper can contact the inner wall of the medicine mixing device. Driven by the rotation of the stirring rod 102, these scrapers 106 can be used to scrape off the powder remaining on the inner wall, so that the powder residue after each mixing will not cause inappropriate cross-mixing in the subsequent mixing process and affect the medication effect.

[0003] However, the above-mentioned existing mixing device still has the following disadvantages: since the scraper support rod 105 is not continuous but welded section by section, the length and welding consistency requirements are high. If the welding is inconsistent, part of the scraper blade will not scrape the side wall, resulting in scraping wall faults, and from Figure 1 It can be clearly seen that each scraper support rod 105 extends obliquely downward. This oblique axis will be subjected to axial and radial forces at the same time during stirring, so the force is relatively large and it is easier to bend, resulting in the wall scraping effect being easily deteriorated after long-term use.

[0019] Figure 3 The utility model is provided with a schematic diagram of the internal structure of an embodiment of a medicine mixing device with a scraper. DETAILED DESCRIPTION

[0020] The core of the utility model is to provide a medicine mixing device with a scraper, which adopts a continuous scraper shaft to fix the scraper, so as to ensure that each scraper is in close contact with the side wall, and the support is more durable and will not bend, so as to ensure a good wall scraping effect after long-term work and better avoid the mold of medicine residue.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a medicine mixing device with a scraper. Figure 2 and Figure 3 As shown, Figure 2 This is an overall external schematic diagram of an embodiment of a medicine mixing device with a scraper provided by the utility model. Figure 3 The present invention is a schematic diagram of the internal structure of an embodiment of a medicine mixing device with a scraper provided by the utility model, wherein the medicine mixing device with a scraper may include a medicine bin 1, a stirring drive component 2, and a stirring rod 3 extending downward into the medicine bin 1 and electrically connected to the stirring drive component 2, a scraper shaft 4 is fixed to the stirring rod 3, the scraper shaft 4 extends continuously in a serpentine shape from the upper part to the lower part of the stirring rod 3 with the stirring rod 3 as the axis, and the scraper shaft 4 as a whole includes a plurality of protruding units 41, a scraper 5 is installed on the protruding edge of each protruding unit 41, and the free edge of each scraper 5 away from the stirring rod 3 is in close contact with the inner wall of the medicine bin 1.

[0023] It should be noted that the medicine bin 1 is used to place a variety of medicines that need to be mixed. The stirring drive component 2 can drive the stirring rod 3 to rotate, so that the scraper shaft 4 fixed thereon can be driven to rotate, thereby driving all the scrapers 5 to rotate. The stirring drive component 2 can be specifically a stirring motor. This stirring motor can be fixed to the medicine bin cover by screws, and the stirring rod 3 can be fixed by a coupling. When powered on, the stirring rod 3 is driven to rotate clockwise to mix the powder in the medicine bin 1 evenly. During the rotation process, since the scraper 5 is in close contact with the inner wall of the medicine bin 1, the medicine remaining on the inner wall surface of the medicine bin 1 can be scraped off to avoid residue and mold, and all heights of the inner wall of the medicine bin 1 can be fully covered by these scrapers 5, so that the scraping is more thorough. It should also be noted that during the rotation process, the scraper shaft 4 itself will also stir the medicines in the medicine bin 1, thereby enhancing the stirring effect and making the medicines mixed more evenly. It should be emphasized that the scraper shaft 4 used here is a continuous serpentine extension, extending from Figure 3It can be seen that the connection parts of the scraper shaft 4 and the stirring rod 3 are perpendicular to the stirring rod 3. Therefore, during the rotation of the scraper 5, even if it is subjected to the reverse thrust of the inner wall of the medicine bin 1, this reverse thrust is also in the horizontal direction, and there is no vertical force component like in the prior art. Therefore, most of the reverse thrust of this scheme can offset each other, just like Figure 3 In this way, when there is a horizontal reverse thrust to the left, there is also a horizontal reverse thrust to the right, and the two can offset each other, so it is not easy to cause the scraper shaft 5 to bend. In this way, the service life of the scraper shaft 5 can be longer, the connection is more firm, and the scraping effect on the inner wall can be maintained for a longer time, making the scraping cleaner and preventing residual drugs from causing pollution to the next round of mixing process.

[0024] in addition, Figure 2 Also shown is an equipment frame 6 for supporting the medicine bin 1, a weighing sensor gasket 7 mounted on the equipment frame 6, and a weighing sensor 8 arranged thereon. The weighing sensor 8 is used to weigh the medicine bin 1 to achieve accurate control of the amount of medicine discharged. There may be punching holes for the weighing sensor gasket 7 on the equipment frame 6. The weighing sensor gasket 7 may be fixed to the equipment frame 6 by screws and nuts, and then the weighing sensor 8 is mounted on the weighing sensor gasket 7. The main function of the weighing sensor gasket 7 is to increase the fixing area of ​​the weighing sensor 8 and avoid the weighing value. Affected by interference, the main drug mixing part of the equipment is a conical medicine bin 1, which can be fixed on the weighing sensor 8 by screws and nuts. In addition, it also includes a medicine receiving barrel 9 for receiving the medicine discharged from the medicine bin 1 and an auger 10 for discharging the medicine from the medicine bin 1. After the medicine receiving barrel 9 receives the medicine, it can be transported away to realize the feeding of pigs. It also includes a control console 11 for controlling the mixing process and the drug transportation process. The weighing sensor 8 can monitor the weight of the powder inside the medicine bin in real time by the control console 11. Its main function is to quantitatively control the amount of medicine discharged from the medicine bin 1. In addition, the medicine bin cover 12 at the top is also shown. When the medicine needs to be put into the medicine bin 1, the medicine bin cover 12 can be opened, and when it is put in, it can be closed, and then the medicine can be mixed, which can prevent the medicine from coming out from the top, and can also prevent external debris from entering the medicine bin 1 to contaminate the medicine, improve the cleanliness of the medicine, and also play a moisture-proof role. In this case, while stirring, the control console will control the auger motor to drive the auger to rotate, and spirally push the mixed powder into the barrel containing the powder. The weighing sensor will provide real-time feedback on the remaining powder inside the medicine bin to achieve accurate drug placement. During the mixing process, the scraper on the stirring rod will scrape off the powder stuck on the inner wall of the barrel medicine bin to prevent the powder from sticking to the inner wall and affecting the next mixing effect, thereby indirectly avoiding the risk of cross-drug use in pigs.

[0025] It can be seen from the above technical scheme that in the embodiment of the above-mentioned medicine mixing device with scraper provided by the utility model, since it includes a medicine bin, a stirring drive component and a stirring rod extending downward into the medicine bin and electrically connected to the stirring drive component, a scraper shaft is fixed on the stirring rod, and the scraper shaft extends continuously in a serpentine shape from the upper part to the lower part of the stirring rod with the stirring rod as the axis, and the scraper shaft as a whole includes a plurality of protruding units, and the protruding edge of each protruding unit is equipped with a scraper, and the free edge of each scraper away from the stirring rod is in close contact with the inner wall of the medicine bin. It can be seen that the scheme adopts a continuous scraper shaft to fix the scraper, which can ensure that each scraper is in close contact with the side wall, and the scraper shaft is no longer subjected to oblique force, so it can support more durable and will not bend, which can ensure a good wall scraping effect after long-term work and better avoid drug residue and mold.

[0026] In a specific embodiment of the above-mentioned drug mixing device with a scraper, the scraper shaft 4 can be an integrated scraper shaft, and the scraper shaft 4 and the stirring rod 3 can be fixed together by welding. It should be noted that this integrated scraper shaft can be produced at one time without any connecting parts in the middle, so as to ensure better firmness, and this scraper shaft 4 can be fixed to the stirring rod 3 by welding, and it is welded at each position in contact with the stirring rod 3 to make the two become a solid whole. Of course, other connection methods can also be selected according to actual needs, such as riveting, bolt connection, etc., which are not limited here.

[0027] In another specific embodiment of the above-mentioned medicine mixing device with a scraper, the above-mentioned protruding unit 41 can specifically include a U-shaped unit located in the upper area of ​​the stirring rod 3, which can be as follows: Figure 3 As shown, the above three can be called U-shaped units, which have two sides along the horizontal direction and one side along the vertical direction, and a scraper blade 5 is fixed on the vertical side, and the scraper blade 5 contacts the inner wall of the medicine bin along the vertical direction. In fact, this matches the shape of the upper part of the medicine bin, because the upper part of the medicine bin is cylindrical. Therefore, in the process of scraping medicines at this position, the reaction force applied by the inner wall to the scraper blade 5 is along the horizontal direction, and there will be no oblique component, and the reaction forces in the left and right directions can offset each other, thereby not causing the scraper shaft 4 to bend, and thus the service life can be longer.

[0028] In another specific embodiment of the above-mentioned medicine mixing device with a scraper, the protruding unit 41 may also include a U-shaped unit located in the middle area of ​​the stirring rod, and the angle of the free edge of the U-shaped unit away from the stirring rod matches the angle of the inner wall of the medicine bin where it is located. Figure 3, the fourth to the sixth from the top can be called the above-mentioned U-shaped unit. In addition to the two sides along the horizontal direction, this U-shaped unit also has a middle side with a certain angle with the vertical direction. The scraper 5 is fixed on the middle side. This is to match the conical inner wall here. Its inclination angle must be consistent with the conical inner wall here to achieve effective scraping of the medicine on the conical inner wall. In this case, although the conical inner wall will exert an oblique reaction force on the middle side, the force is transmitted through the two sides along the horizontal direction. Therefore, this force transmission method can also ensure that the reaction forces on both sides offset each other and better avoid deformation. Further, the above-mentioned protruding unit 41 can also include a L-shaped unit located in the lower area of ​​the stirring rod 3, and the angle of the free edge of the L-shaped unit away from the stirring rod matches the angle of the inner wall of the medicine chamber where it is located. It should be noted that this shape is set to match the inner wall here. After all, the lowest circular part needs to be together. Therefore, in order to scrape the medicine on the inner wall here, the protruding unit here must be set to an L-shaped unit. Since it is close to the stirring rod 3, the reaction force can be transmitted to the stirring rod 3 more quickly. It can also ensure that this position is not easy to deform, ensuring that the whole has a longer service life. Furthermore, the upper shape of the above-mentioned medicine bin 1 is preferably cylindrical, the lower shape is preferably conical, and the number of U-shaped units can be preferably 3 to 4, the number of U-shaped units can be preferably 3 to 4, and the number of L-shaped units can be preferably 1. Of course, these can all be selected according to actual needs. The size of each unit can also be adjusted according to actual conditions, and is not limited here. There is an overlapping portion between the contact surface of the scraper 5 connected to the adjacent protruding units 41 and the inner wall, and the height of the overlapping portion can be preferably 10mm to 20mm. It should be noted that if there is no overlapping portion between the two, then there will inevitably be medicine overflow at the edge to form residues. After setting such an overlapping portion, even if a certain part of the inner wall is scraped by a scraper 5 to form medicine residues, then when another adjacent scraper 5 arrives, these residual medicines can also be scraped away. It can be seen that the medicines on the inner wall can be scraped more cleanly. Of course, the height of the overlapping portion can be selected according to actual conditions, for example, it can be selected according to the viscosity of the medicine. The greater the viscosity of the tablet, the height of the overlapping portion can be set larger to improve the scraping effect.

[0029] In a preferred embodiment of the above-mentioned drug mixing device with a scraper, continue to refer to Figure 3The scraper blade 5 can be fixed to the scraper shaft 4 by a connecting plate 13, wherein the connecting plate 13 and the scraper shaft 4 are preferably welded together, and the connecting plate 13 and the scraper blade 5 can be preferably fixed together by bolts. It can be seen that the use of such a connecting plate 13 can ensure that the scraper blade 5 is firmly fixed to the scraper shaft 4, so that the inner wall reaction force of the scraper blade 5 is better transmitted to the scraper shaft 4 without deflection. Of course, other connection methods can also be selected according to actual needs, which is not limited here.

[0030] In another preferred embodiment of the above-mentioned drug mixing device with a scraper, continue to refer to Figure 3 , a single spiral blade 14 is also fixed on the stirring rod 3, and the single spiral blade 14 is distributed throughout the middle preset area of ​​the stirring rod 3, wherein the middle preset area is the area except for the stirring rod height area corresponding to the height of the top protruding unit and the stirring rod height area corresponding to the height of the bottom protruding unit. Specifically, a circle of counterclockwise right-handed spiral blades is welded on the middle shaft of the stirring rod 3, and its function is to stir and mix the powder in the medicine bin, prevent uneven mixing of the medicine and adhesion to the barrel wall. It can be seen that the use of this single spiral blade 14 can further improve the stirring effect, and consume less energy, and the production cost can be reduced.

[0031] In another preferred embodiment of the above-mentioned drug mixing device with a scraper, the ratio of the height of the cylindrical part of the medicine bin 1 to the height of the conical part of the medicine bin 1 can be preferably 1:1.2 to 1:1.6. Such a taper can allow the medicine to flow more smoothly, thereby reducing drug residues, and the drug injection port of the medicine bin can preferably extend upward by a preset distance. The preset distance can be selected according to actual needs. After the extension, it is more convenient to put in the medicine, thereby improving convenience.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
