[0024] 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.

[0025] Example: Reference Figure 1-6 A new type of automatic filter opening and closing mechanism shown in the figure includes a peeling and crushing machine 1, a separation tank position of the peeling and crushing machine 1, a filter assembly is rotatably connected, an inner stirring paddle 2 is slidably connected at the inner ring position of the filter assembly, and the inner stirring paddle 2 is connected to a power assembly arranged inside the peeling and crushing machine 1, thereby achieving the purpose of controlling the inner stirring paddle 2 to rotate inside the filter assembly, and the filter assembly is connected to the power assembly through a gear set, thereby achieving the purpose of controlling the filter assembly to rotate above the separation tank.

[0026] Filter assembly: There are four groups of fixed rings 3, and two adjacent groups of fixed rings 3 are connected by reinforcing ribs 7, so as to achieve the purpose of connecting the four groups of fixed rings 3 in sequence. The leftmost fixed ring 3 is connected to the power assembly through a gear set, and the outer walls of the remaining three groups of fixed rings 3 are provided with guide rings 6, which are used to connect the support plate. The guide rings 6 are slidably connected to the support plate. Therefore, under the drive of the power assembly, the fixed rings 3 are driven by the gear set to rotate above the separation groove, and a filter screen 9 for achieving the separation purpose is provided on the fixed ring 3 to separate the food.

[0027] A ring gear 4 is provided on the outer wall of the leftmost fixed ring 3, which meshes with a driving gear 5 rotating on the outer wall of the peeling and crushing machine 1, so that when the power assembly is started, the ring gear 4 is driven to rotate through the driving gear 5.

[0028] Each set of fixing rings 3 is provided with a through hole 31, and the through holes 31 are connected by an opening rod 8. There are two sets of opening rods 8 symmetrically arranged, and the opening rods 8 are rotatably connected in the through holes 31. An opening gear 10 is provided on the end face of the opening rod 8. The two sets of opening gears 10 are meshed with each other, so that when one set of opening rods 8 is driven to rotate, the other set of opening rods 8 rotates synchronously, thereby opening the filter screen 9 and cleaning its inner wall.

[0029] A limiting mechanism is provided on the end face of one group of opening gears 10. The connecting piece 11 of the limiting mechanism is a U-shaped piece. An L-shaped limiting rod 12 is hinged at the end position of its groove. A torsion spring is provided at the hinge point of the limiting rod 12, so that the outward end of the limiting rod 12 is always flipped and pressed into the limiting groove 81 of the opening rod 8 of the other group. Therefore, before the power mechanism comes into contact with the limiting rod 12 of the limiting mechanism, the two groups of opening rods 8 are limited (locked and rotation is prohibited) to avoid the two groups of filter screens 9 from opening due to the influence of weight during use.

[0030] A telescopic cylinder 13 is provided on the outer wall of the peeling and crushing machine 1. The telescopic cylinder 13 is powered on and started to control the telescopic end to work. The placement plate provided on the telescopic end is used to place the motor 14. In order to realize the opening and closing of the filter 9, the telescopic cylinder 13 is retracted during use, so that the connecting head 15 on the driving shaft of the motor 14 is inserted into the U-shaped groove of the connecting piece 11, and the limiting rod 12 is squeezed so that the outward end of the limiting rod 12 leaves the limiting groove 81, and the limiting of the two groups of opening rods 8 is released. Then the motor 14 is started to open the filter 9 for cleaning operation, otherwise it is closed.

[0031] A fixed head 91 is provided on the top of the filter 9, and the fixed head 91 is coaxially arranged with the opening rod 8. The opening rod 8 rotates to drive the filter 9 to open and close. The fixed groove 92 provided on the inner wall of the filter 9 is adapted to the reinforcing rib 7 to avoid a dead angle between the two in the closed state, which leads to food hoarding and bacterial growth.

[0032] The working principle of the utility model is as follows: the raw material is put into the peeling and crushing machine 1, and then it is transported to the filtering component for separation operation. Under the drive of the power component, the internal stirring paddle 2 and the filtering component are controlled to rotate to realize the separation operation. After the processing is completed, the internal stirring paddle 2 and the filtering component are stopped, and then the telescopic end of the telescopic cylinder 13 is retracted, so that the motor 14 on the placement plate moves toward the connecting piece 11, and the connecting head 15 on the driving shaft of the motor 14 is inserted into the connecting piece 11, and the limiting rod 12 is squeezed to make the limiting rod 12 tilt up and leave the limiting groove 81, so as to release the limiting of the two sets of opening rods 8, and then the motor 14 works, through the limiting between the connecting head 15 and the connecting piece 11 The rotating opening gears 10 drive another group of opening gears 10 to rotate, and then drive the coaxially arranged opening rod 8 to rotate in the through hole 31 of the fixing ring 3, open the fixed head 91 coaxially connected to the opening rod 8, and the fixed head 91 drives the filter screen 9 to open, and then the cleaning operation is carried out. After the cleaning is completed, the motor 14 is reversed to close the two groups of filter screens 9 again, and the fixing groove 92 is re-fitted with the reinforcing rib 7, and then the telescopic end of the telescopic cylinder 13 is extended to separate the connecting head 15 from the connecting piece 11, and under the action of the torsion spring, the limiting rod 12 is re-entered into the limiting groove 81 to complete the limiting and achieve closure.

[0033] The guide ring 6 provided on the outer wall of the fixed ring 3 rotates on the support plate, and the guide groove on the support plate cooperates with the guide ring 6 to achieve limiting and support at the same time. The ring gear 4 of the gear set is meshed with the driving gear 5 on the outer wall of the peeling crusher 1. Due to the differential ratio, the rotation speeds of the inner stirring paddle 2 and the ring gear 4 are different, forming a state of slow outside and fast inside.

[0034] The electromechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.

[0035] Components not described in detail herein are prior art.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
