TECHNICAL FIELD
[0001] The present application relates to the technical field of grain processing equipment, in particular to a flat rotary swing type stone removing machine for waxy rice processing. BACKGROUND
[0002] The stone removing machine is a grain cleaning machine that separates light and heavy impurities from materials by using the difference in specific gravity and friction coefficient between the materials and impurities (mainly stones and mud blocks), through the vibration of the screen body and the action of air flow, and is mainly used for removing heavy impurities such as stones during the processing of rice, wheat and other grains to ensure the safe operation of subsequent processing equipment and the quality of finished grain.
[0003] However, the existing equipment often encounters the following problems during use: When the traditional stone removing machine screens stones and chaff, the whole stone removing machine needs to be shaken back and forth, and then the screening is performed through the slope of the stone removing machine itself. However, due to the back and forth shaking and the guidance of the slope, the falling material curtain quickly falls back to the screen. Since the whole process is fast, the falling material curtain cannot fully spread on the screen of the stone removing machine, resulting in poor screening effect. SUMMARY
[0004] The main purpose of the present application is to provide a flat rotary swing type stone removing machine for waxy rice processing. The present application is designed to solve the problem that the traditional stone removing machine needs to be shaken back and forth as a whole when screening stones and chaff, and then the screening is performed through the slope of the stone removing machine itself. However, due to the back and forth shaking and the guidance of the slope, the falling material curtain quickly falls back to the screen. Since the whole process is fast, the falling material curtain cannot fully spread on the screen of the stone removing machine, resulting in poor screening effect. The present application generates horizontal rotation motion through the shaking mechanism at the bottom. This motion is output to the displacement transmission mechanism through the distance adjusting rod. The core of the displacement transmission mechanism is a cross slide pair composed of a transverse sliding rod and a plane sliding rod, which strictly constrains the rotation motion to an elliptical trajectory translation in the horizontal plane without rotation, and finally transmits this motion to the stone removing machine screen body through the connecting base. This makes the material on the screen evenly thrown to the surrounding under the action of centrifugal force, fully spread to form a thin and uniform curtain, thereby overcoming the problem of incomplete screening caused by fast linear reciprocating vibration of the traditional equipment.
[0005] To achieve the above purpose, the technical solution adopted by the present application is as follows: A flat rotary swing type stone removing machine for waxy rice processing, comprising: a feeding shell, which is installed above the stone removing machine screen body; a stone removing machine screen body, which is integrated with the feeding shell; A stone removing machine base is installed on the bottom surface of the stone removing machine screen body; A reset spring is connected between the stone removing machine base and the stone removing machine screen body; A machine body frame is provided at least two, which is a frame structure arranged side by side; A movable base is transversely arranged between the two machine body frames, and is movably connected with the machine body frame through the universal joint; An external base is installed on one side of the movable base; A shaking mechanism is installed on the external base; A displacement transmission mechanism is arranged above the movable base and connected with the stone removing machine base.

[0007] The circumferential driving member comprises: A bottom driving wheel; A sleeved rod is fixedly connected with the center shaft of the bottom driving wheel at the bottom end and is sleeved on the rod body of the fixed rod; A base frame, the top end of the fixed rod penetrates the base frame, the cross beam rod is arranged in the base frame; A driving motor, the driving motor is located below the outer base, and an output end of the driving motor is connected with the bottom driving wheel.
[0008] The displacement transmission mechanism comprises: A displacement base, the displacement base is fixed above the movable base; Transverse sliding rods, the transverse sliding rods are arranged in parallel on the displacement base; Transverse sliding members, the transverse sliding members are sleeved on the transverse sliding rods; Plane sliding rods, the plane sliding rods are arranged in parallel, and the extending directions of the plane sliding rods are perpendicular to the transverse sliding rods; Linkage plates, the linkage plates are connected to the end portions of the plane sliding rods, and the bottom surface of one of the linkage plates is movably connected to the top end of the distance adjusting rod; A connecting base, the connecting base is fixedly connected with the stone removing machine base.

[0011] The top end of the distance adjusting rod is movably connected to the input end of the displacement transmission mechanism.
[0012] The connecting base is sleeved on the middle section of the plane sliding rod.
[0013] The bottom surface of the base frame is fixedly connected to the top end of the sleeved rod.
[0014] The movable base is not in contact with the ground.
[0015] Compared with the prior art, the beneficial effects of the present application are that the shaking mechanism located at the bottom generates horizontal plane rotation, which is output to the displacement transmission mechanism through the distance adjusting rod. The core of the displacement transmission mechanism is a cross sliding pair composed of the transverse sliding rod and the plane sliding rod, which strictly restricts the rotation of the rotation to an elliptical trajectory translation in the horizontal plane, and finally transmits the motion to the stone removing machine screen body through the connecting base. This makes the material on the screen uniformly thrown to the surrounding under the action of centrifugal force, completely expands to form a thin and uniform waterfall, thereby overcoming the problem of incomplete screening caused by rapid linear reciprocating vibration of traditional equipment.

Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.
[0025] In the description of the present application, it is further noted that, unless otherwise explicitly specified and limited, the terms "arranged", "arranged", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected, it can be mechanically connected, or electrically connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements.

[0026] As Figures 1-6 The present application provides a waxy rice processing flat swing type stone removing machine, which comprises a feeding shell 1, a stone removing machine sieve body 2, a stone removing machine base 3, a reset spring 4, a machine body frame 5, a movable base 6, an external base 7, a shaking mechanism 8 and a displacement transmission mechanism 9.
[0027] The feeding shell 1 is installed above the stone removing machine sieve body 2, and the stone removing machine sieve body 2 is integrated with the feeding shell 1; the stone removing machine base 3 is installed on the bottom surface of the stone removing machine sieve body 2, the reset spring 4 is connected between the stone removing machine base 3 and the stone removing machine sieve body 2, the machine body frame 5 is provided in at least two, the machine body frame 5 is a frame structure arranged side by side, the movable base 6 is transversely arranged between the two machine body frames 5, the movable base 6 does not contact the ground, and the movable base 6 is movably connected with the machine body frame 5 through a universal joint; the movable base 6 constitutes a suspension system. The universal joint allows the movable base 6 to swing in multiple directions, rather than being rigidly fixed. The purpose is to release the constraint, so that the movable base 6 can perform complex translation motion in the horizontal plane, while limiting its overall large displacement in the vertical direction, and transmitting the driving force to the sieve body above.
[0028] In the present application, the external base 7 is installed on one side of the movable base 6, and the shaking mechanism 8 is installed on the external base 7; the output end of the shaking mechanism 8 is movably connected with the input end of the displacement transmission mechanism 9, the displacement transmission mechanism 9 is arranged above the movable base 6, and the displacement transmission mechanism 9 is connected with the stone removing machine base 3.
[0029] In the present application, the shaking mechanism 8 comprises: a circumferential driving member 81 vertically installed on the external base 7; the circumferential driving member 81 serves as a primary motion generator of the system. Its core function is to convert the rotary motion of the motor into the revolution motion of the driving frame 85 around the axis of the fixed rod 82. The fixed rod 82 is sleeved in the circumferential driving member 81, and a fixed gear 83 is installed at the top end of the fixed rod 82; the fixed rod 82 serves as a stationary reference system of the whole shaking mechanism 8. The fixed rod 82 provides the axis for the revolution of the circumferential driving member 81. The fixed gear 83 is engaged with a driving gear 87, and the "fixed" characteristic is the key, which can convert the revolution motion of the driving frame 85 into the rotation of the driving gear 87.
[0030] In the present application, as shown in Figure 5 The beam rod 84 is arranged on the top of the circumferential driving member 81, the driving frame 85 is fixedly connected with the arranged end of the beam rod 84, the driving rod 86 is parallel to the beam rod 84 and is rotatably arranged on the circumferential driving member 81, the driving gear 87 is sleeved on the rod body of the driving rod 86 and is engaged with the fixed gear 83, the adjusting tooth disc 88 is installed on the arranged end of the driving rod 86 and is located inside the driving frame 85, the amplitude rod 89 is horizontally arranged on the driving frame 85, the amplitude gear 810 is sleeved on the rod body of the amplitude rod 89 and is engaged with the adjusting tooth disc 88; when the driving frame 85 revolves, the driving rod 86 is forced to rotate due to the engagement between the driving gear 87 and the fixed gear 83. The rotation of the driving rod 86 is transmitted to the amplitude gear 810 through the adjusting tooth disc 88, and then the amplitude rod 89 is driven to rotate. The rotation angle of the amplitude rod 89 and the revolution angle of the driving frame 85 always maintain a fixed mathematical relationship determined by the gear transmission ratio. This makes the pointing direction of the distance adjusting frame 811 be able to automatically synchronize with the revolution movement.
[0031] In the present application, the distance adjusting frame 811 is fixedly connected with the top end of the amplitude rod 89, the distance adjusting rod 812 is partially located on the top end of the distance adjusting frame 811 and is slidably connected with the distance adjusting frame 811 through bolts, and the top end of the distance adjusting rod 812 is movably connected with the input end of the displacement transmission mechanism 9. The extension length of the distance adjusting rod 812 in the distance adjusting frame 811 is equivalent to the radius eccentricity of the crank.
[0032] In the present application, the circumferential driving member 81 comprises: the bottom end of the sleeved rod 10 is fixedly connected with the central shaft of the bottom driving wheel 9, the rod body of the sleeved rod 10 is sleeved on the fixed rod 82, the top end of the fixed rod 82 penetrates through the base frame 11, the beam rod 84 is arranged on the base frame 11, the bottom surface of the base frame 11 is fixedly connected with the top end of the sleeved rod 10, the driving motor 12 is located below the outer base 7, and the output end of the driving motor 12 is connected with the bottom driving wheel 9.
[0033] In the present application, as shown in Figures 3-4As shown, the displacement transmission mechanism 9 includes: a displacement base 91 fixed above the movable base 6; the displacement base 91 as an intermediate platform of motion transmission, is fixed with the movable base 6 and moves together with it. At least two horizontal sliding rods 92 are arranged in parallel on the displacement base 91, a horizontal sliding part 93 is sleeved on the horizontal sliding rod 92, and at least two plane sliding rods 94 are arranged in parallel, the extension direction of the plane sliding rod 94 is perpendicular to the horizontal sliding rod 92; the plane sliding rod 94 penetrates through the horizontal sliding part 93. The horizontal sliding rod 92 and the horizontal sliding part 93 constitute a linear guide pair. Its function is to allow the components connected thereto to freely slide left and right along the plane sliding rod 94 in a single direction, while restricting the movement in other directions. The plane sliding rod 94 and the horizontal sliding part 93 constitute another linear guide pair perpendicular to the former. Its function is to allow the connecting base 96 to freely slide in the front and back directions.
[0034] The linkage plate 95 is connected to the ends of the two plane sliding rods 94, one bottom surface of the linkage plate 95 is movably connected to the top end of the distance adjusting rod 812, and the connecting base 96 is fixedly connected to the stone removing machine base 3. The connecting base 96 is sleeved on the middle segment of the plane sliding rod 94 and is a cross-shaped linear guide or a two-degree-of-freedom linear motion system. Its core function is to convert the rotary / circular motion of the input end into pure translational motion of the output end. It restricts the connecting base 96 to only perform left and right and front and back translations in the horizontal plane, and cannot rotate. When the circular motion of the top end of the distance adjusting rod 812 is input to the linkage plate 95, the motion is decomposed into two orthogonal linear motions by the cross sliding pair, and the combined trajectory is an accurate elliptical translational oscillation.
[0035] If it is necessary to adjust the size of the circular trajectory, so that the shaking amplitude is reduced, the bolt can be loosened, the distance adjusting rod 812 is pulled, the position of the connecting part of the distance adjusting rod 812 and the linkage plate 95 is adjusted relative to the position of the distance adjusting frame 811, the motor is started, the drive gear 87 of the drive rod 86 is relatively rotated due to the engagement with the fixed gear 83, the rotation of the drive gear 87 means that the drive rod 86 performs axial rotation, the drive rod 86 in rotation drives the adjusting gear 88 at one end to rotate, the adjusting gear 88 drives the amplitude gear 810 to rotate in turn, the amplitude gear 810 drives the amplitude rod 89 to perform axial rotation, the amplitude rod 89 in rotation drives the distance adjusting frame 811 at the top to rotate, at this time, the closer the connecting position of the distance adjusting rod 812 and the linkage plate 95 to the position of the distance adjusting frame 811, the smaller the rotation amplitude and the centrifugal force, the shorter the distance adjusting rod 812 extends, the smaller the force arm, and finally the smaller the motion trajectory of the connecting base 96.
[0036] Needle to say, the designed waxy rice processing flat swing stone removing machine, when in use, once the material reaches the screen of the stone removing machine 2 through the feed inlet of the stone removing machine, the driving motor 12 is started, the output end of the motor rotates, the circumferential driving part 81 rotates around the fixed gear 83, the rotation of the circumferential driving part 81 means that the driving rod 86 and the cross beam rod 84 are also driven, first measure the feeling, the base frame 11 is driven to rotate, the cross beam rod 84 in rotation will rotate together with the driving frame 85, the driving frame 85 will pull the top distance adjusting rod 812 in the horizontal direction to swing in a circle, finally the distance adjusting rod 812 drives the linkage plate 95 to move together, in the circular displacement motion track, the driven linkage plate 95 slides in the transverse sliding part 93 through the flat sliding rod 94, completes the displacement of the front and rear tracks, and the transverse sliding key is pulled together, the left and right tracks are displaced in the rod body of the transverse sliding rod 92, the combination is reflected to the connecting base 96, when the distance adjusting rod 812 provides a circular input, the circular motion is decomposed into simple harmonic motion in front and rear and left and right directions by the cross sliding pair, and the combined track is an ellipse. The swing of the circular track in the plane direction is realized, finally the stone removing machine is driven to swing in a circular track, the material formed by the feed inlet of the stone removing machine is completely separated from the track of the circular swing of the stone removing machine, so that the material is completely filled on the surface of the screen.
[0037] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, alternatives and variations can be made to these embodiments by those of ordinary skill in the art without departing from the spirit and scope of the present application, the scope of which is defined by the appended claims and their equivalents.
