Technical Field
[0001] The utility model belongs to the technical field of filters, and in particular relates to a small berry filtering device which is easy to clean. Background Art
[0002] Small berries such as blueberries are inevitably mixed with branches and leaves or soil when picked, so they need to be rinsed and filtered with clean water. In order to save manpower, the picked berries should be placed in a sink, soaked for 3-5 minutes, and the surface should be rinsed with running water to remove soil and branches and leaves.
[0003] A horizontally sliding hopper is usually installed in a traditional water tank, and many water leakage holes are opened on the surface of the hopper. The motor is used to shake the hopper and the berries inside it left and right, and the mud on the surface of the berries is carried away by the water flow and filtered out from the water leakage holes.
[0004] When the existing berries are cleaned and filtered, they are placed in a hopper with a leaking hole, soaked and rinsed with water, and shaken left and right by a motor. The shaking of the berries will hit the two side walls of the hopper, and some ripe berries will break due to the impact and leak juice, so that the sticky juice adheres to the inner wall of the hopper, which increases the burden of subsequent cleaning. For this reason, we propose a small berry filtering device that is easy to clean. Utility Model Content
[0005] The utility model aims to provide a small berry filtering device which is easy to clean and can drive the berries to swing along the circumference, so as to avoid partially ripe berries hitting the screen plate and causing rupture and outflow of juice, thereby reducing the burden of subsequent cleaning.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A small berry filtering device that is easy to clean, comprising a water tank, the water tank is a cylindrical structure with an upper opening, a driving mechanism is arranged on the outside of the water tank, a sieve plate is arranged at the opening of the water tank, the middle of the sieve plate is concave in an arc surface toward the inside of the water tank and the arc surface is wavy, a plurality of water leakage holes are arranged at intervals on the sieve plate, and a gear ring is fixed on the outside of the sieve plate;
[0008] The driving mechanism comprises a servo motor fixedly connected to the outside of the water tank, the output end of the servo motor faces upward and a driving gear is fixed to the output end, the teeth of the driving gear and the teeth on the outside of the gear ring are meshed with each other, when cleaning, some berries are piled inside the sieve plate and continuously rinsed with clean water, the water flow carries the soil through the leaking hole into the water tank, and is discharged along the water outlet of the water tank, while the branches and leaves float on the water surface, and the berries sink in the water and are separated from the branches and leaves; at the same time, the servo motor is started, the driving gear is intermittently rotated forward, and then reversed with the same amplitude, the gear ring can be used to drive the sieve plate to swing back and forth in the horizontal direction to generate a centrifugal effect, drive the berries to swing along the circumference, and these berries fall toward the middle of the sieve plate along the wavy arc surface during the stop interval, so as to avoid the partially ripe berries hitting the sieve plate to cause rupture and outflow of juice, reduce the juice attached to the water tank and the sieve plate, and reduce the burden of subsequent cleaning.
[0009] A hard pipe is fixed on one side of the water tank away from the driving mechanism. The upper end of the hard pipe extends above the gear ring and bends toward the sieve plate. The water source valve is opened and the water pump is started to suck clean water. The clean water can be pumped along the hard pipe and sprayed onto the sieve plate. The hard pipe can resist the reaction of the water flow and stabilize the water discharge.
[0010] A support ring is rotatably installed on the upper surface of the water tank, the central axis of the support ring coincides with the central axis of the water tank, the upper surface of the support ring is close to the lower surface of the gear ring, and the support ring is used to support the sieve plate. The supporting surface is wide, so that the sieve plate will not rub the water tank when rotating.
[0011] A ring-shaped enclosure is fixed on the upper edge of the water tank. As the screen plate swings, some clean water may be thrown away and splashed. The vertical enclosure is used to block it to prevent water from splashing outward during the cleaning process.
[0012] A drain valve is fixed on the lower surface of the water tank. When cleaning starts, the drain valve can be closed until a certain amount of clean water is stored in the water tank, which can submerge the waist of the sieve plate, so that the berries are conveniently soaked in the clean water. Then the drain valve is opened to keep the water inlet and outlet in a dynamic balance, so that the clean water can submerge the surface of the berries. Finally, the water source is turned off and the dirty water is drained with the drain valve.
[0013] Handles are fixed on both sides of the sieve plate, and a distance is left between the two handles and the enclosure. After cleaning, the branches and leaves are obviously gathered at the top of the sieve plate and can be taken out by hand, and the berries fall in the middle of the sieve plate. You can hold the two handles with both hands, lift the sieve plate and the gear ring upwards, then tilt it to pour out the berries and put them in a clean basin.
[0014] The technical effects achieved by the utility model are:
[0015] The utility model discloses a small berry filtering device which is easy to clean. When cleaning, some berries are piled inside a sieve plate and continuously rinsed with clean water. The water flow carries mud through a water leakage hole into a water tank and is discharged along a water outlet of the water tank.

[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.
[0023] like Figure 1-4 As shown, a small berry filtering device that is easy to clean includes a water tank 1, the water tank 1 is a cylindrical structure with an upper opening, a driving mechanism is arranged on the outer side of the water tank 1, a sieve plate 2 is arranged at the opening of the water tank 1, the middle of the sieve plate 2 is concave in an arc surface toward the inside of the water tank 1, and the arc surface is wavy, a plurality of water leakage holes 3 are arranged at intervals on the sieve plate 2, and a gear ring 4 is fixed on the outer side of the sieve plate 2;
[0024] The driving mechanism includes a servo motor 6 fixedly connected to the outside of the water tank 1. The servo motor 6 can be a YEJ series three-phase asynchronous motor, which is controlled by an industrial computer. The output end of the servo motor 6 faces upward and is fixed with a driving gear 5. The teeth of the driving gear 5 and the teeth on the outside of the gear ring 4 are meshed with each other. Blueberries and other berries are small in size, and it is time-consuming and laborious to pick them individually. When picking, they are often pulled as a whole bead, which inevitably entrains some branches and leaves or soil. When washing, some berries are piled inside the sieve plate 2 and continuously rinsed with clean water. The water flow entrains the soil through the leakage hole 3 into the water tank 1 and is discharged along the drain outlet of the water tank 1. The branches and leaves float on the water surface, and the berries sink in the water and are separated from the branches and leaves. The aperture of the leakage hole 3 is smaller than the diameter of the berries, which can complete the washing and filtering of small berries.
[0025] At the same time, start the servo motor 6, intermittently rotate the driving gear 5 forward, and then reverse it with the same amplitude. The ring gear 4 can be used to drive the sieve plate 2 to swing back and forth in the horizontal direction to produce a centrifugal effect, driving the berries to swing along the circumference. During the stop interval, these berries fall toward the middle of the sieve plate 2 along the wavy arc surface, avoiding partially ripe berries from hitting the sieve plate 2 and causing it to break and leak juice, reducing the juice attached to the sink 1 and the sieve plate 2, and alleviating the burden of subsequent cleaning.
[0026] Among them, the rotation speed of the servo motor 6 is often relatively high, and it is necessary to use the gear ratio of the ring gear 4 and the driving gear 5 to change the rotation speed ratio of the servo motor 6 to drive the sieve plate 2, so that the sieve plate 2 can swing intermittently at a lower speed, keeping the berries swinging along the circle without flying away.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a hard tube 7 is fixed on the side of the water tank 1 away from the driving mechanism. The upper end of the hard tube 7 extends to the top of the gear ring 4 and bends toward the sieve plate 2. The lower end of the hard tube 7 is connected to the water source pump. The water source valve is opened and the water pump is started to suck clean water. The clean water can be pumped along the hard tube 7 and sprayed onto the sieve plate 2. The hard tube 7 can resist the reaction of the water flow and stabilize the water discharge.
[0028] like Figure 1 and Figure 3 As shown, a support ring 8 is rotatably installed on the upper surface of the water tank 1, and the central axis of the support ring 8 coincides with the central axis of the water tank 1. The upper surface of the support ring 8 is in close contact with the lower surface of the gear ring 4. The support ring 8 is used to support the sieve plate 2, and the supporting surface is wide, so that the sieve plate 2 will not rub against the water tank 1 when rotating.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a ring-shaped enclosure 9 is fixed on the upper edge of the water tank 1. As the sieve plate 2 swings, some clean water may be thrown away and splashed. The vertical enclosure 9 is used to block it to prevent water from splashing outward during the cleaning process.
[0030] like Figure 2 and Figure 3 As shown, a drain valve 10 is fixedly connected to the lower surface of the water tank 1. When cleaning starts, the drain valve 10 can be closed until a certain amount of clean water is stored in the water tank 1, which can submerge the waist of the sieve plate 2, so that the berries can be soaked in the clean water. Then the drain valve 10 is opened to keep the water inlet and outlet in a dynamic balance, so that the clean water can immerse the surface of the berries. Finally, the water source is turned off and the dirty water is drained with the drain valve 10.
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, handles 11 are fixed on both sides of the sieve plate 2, and a distance is left between the two handles 11 and the enclosure 9. After cleaning, the branches and leaves are obviously gathered at the top of the sieve plate 2 and can be taken out by hand, while the berries fall in the middle of the sieve plate 2. You can hold the two handles 11 with both hands, lift the sieve plate 2 and the gear ring 4 upwards, then tilt it to pour out the berries, and put them in a clean basin.
[0032] The working principle of the utility model is as follows: when washing, some berries are piled inside the sieve plate 2 and continuously rinsed with clean water, the water flow carries the mud through the water leakage hole 3 into the water tank 1, and is discharged along the drain outlet of the water tank 1, while the branches and leaves float on the water surface, and the berries sink in the water and are separated from the branches and leaves;
[0033] At the same time, start the servo motor 6, intermittently rotate the driving gear 5 forward, and then reverse it with the same amplitude. The ring gear 4 can be used to drive the sieve plate 2 to swing back and forth in the horizontal direction to produce a centrifugal effect, driving the berries to swing along the circumference. During the stop interval, these berries fall toward the middle of the sieve plate 2 along the wavy arc surface, avoiding partially ripe berries from hitting the sieve plate 2 and causing it to break and leak juice, reducing the juice attached to the sink 1 and the sieve plate 2, and alleviating the burden of subsequent cleaning.
[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
