Specific implementation
[0017] In the following, the application will be further described in conjunction with the drawings and specific implementation, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.
[0018] Please combine Figures 1 to 9The application discloses a feed mixing system for olive clam culture, which comprises a shell body 1 in vertical cylindrical shape, a first paddle rod 4 rotatably arranged in the shell body 1 in a concentric manner, a first cylinder 5 sleeved outside the first paddle rod 4, a horizontal second supporting arm 13 fixedly connected to the outside of the first cylinder 5, and a second paddle rod 10 inserted into the second supporting arm 13 in parallel with the axis of the first paddle rod 4.
[0019] The shell body 1 is provided with a motion device driven by the one-way rotation of the first paddle rod 4, which can guide the first cylinder 5 to reciprocate in the axial direction of the first paddle rod 4, so as to increase the stirring coverage area of the material, and improve the stirring efficiency and effect.
[0020] The inclination direction of the paddle blade on the first paddle rod 4 is opposite to that of the paddle blade on the second paddle rod 10, so that the rotation directions of the material stirred by the paddle blades of the first paddle rod 4 and the second paddle rod 10 are opposite, the convection between the materials is fully mixed and contacted, and the feed mixing effect is improved.
[0021] A motor is installed on the top of the shell body 1, and the output shaft of the motor is connected to the top of the first paddle rod 4.
[0022] The motion device comprises a first limiting block 7 fixed to the outer wall of the first paddle rod 4, a first limiting groove 6 in closed loop and eight-shaped structure after unfolding is formed in the axial direction of the inner wall of the first cylinder 5, the first limiting block 7 is slidably connected with the first limiting groove 6, a second cylinder 9 parallel to the axis of the first paddle rod 4 is fixed to the top wall of the shell body 1, a first supporting arm 8 above the second supporting arm 13 is fixedly connected to the outside of the first cylinder 5, and the first supporting arm 8 has a through hole through which the second cylinder 9 passes. The first supporting arm 8 can move axially relative to the second cylinder 9 through the through hole.
[0023] The first limiting block 7 continuously slides and rubs the groove wall of the first limiting groove 6 in closed loop and eight-shaped structure after unfolding through the one-way rotation of the first paddle rod 4, and the first cylinder 5 reciprocates in the axial direction of the first paddle rod 4 under the limiting action of the first cylinder 5 and the first supporting arm 8, so as to drive the second paddle rod 10 to reciprocate in the vertical direction of the shell body 1 through the second supporting arm 13, thereby increasing the contact range of the material and improving the stirring efficiency and effect.
[0024] The second supporting arm 13 has a scraper 14 in contact with the corresponding side wall of the shell body 1 at both ends.
[0025] The scraper 14 can scrape the material attached to the inner side wall of the shell body 1 to the bottom of the shell body 1, thereby improving the utilization rate of the material.
[0026] The second paddle rod 10 is rotatably inserted into the second supporting arm 13, and the inner wall of the second barrel 9 is provided with a second limiting groove 11 in the form of a spiral line along the axial direction. The top of the second paddle rod 10 is inserted into the bottom of the second barrel 9, and is fixed with a second limiting block 12 which is in sliding and clamping cooperation with the second limiting groove 11.
[0027] The up-and-down movement of the second paddle rod 10 will cause the second limiting block 12 thereon to be continuously pressed and rubbed by the groove wall of the second limiting groove 11 in the form of a spiral line, so that the second paddle rod 10 will also rotate back and forth while moving up and down, further improving the stirring efficiency and effect.
[0028] The top of the shell 1 is provided with a feeding port 2, and the bottom is provided with a discharging port 3.
[0029] The discharging end of the bottom of the feeding port 2 extends into the shell 1, and the shell 1 is provided with a stop block 24 and a material control mechanism which are in sliding and sealing cooperation with the discharging end of the feeding port 2. The material control mechanism is driven by the rotation of the first paddle rod 4, and can guide the stop block 24 to move back and forth relative to the discharging end of the feeding port 2, so as to intermittently input the material into the shell 1, so that the amount of material input into the shell 1 per unit time remains constant, and the material can be uniformly stirred.
[0030] The material control mechanism comprises a first gear 15 which is sleeved on the outer circumferential side of the first paddle rod 4. The first gear 15 is a gear with missing teeth. The inner top wall of the shell 1 is fixed with a third limiting groove 16 in the form of an arc structure. The bending direction of the groove body of the third limiting groove 16 is matched with the rotation direction of the tooth segment of the first gear 15.
[0031] The third limiting groove 16 is slidably clamped with a third limiting block 17. A first spring is arranged between one side of the third limiting block 17 and the groove wall of the third limiting groove 16. The bottom of the third limiting block 17 is rotatably provided with a second gear 18 which is in intermittent cooperation with the first gear 15. The inner top wall of the shell 1 is elastically provided with a rotating shaft 20. The top of the rotating shaft 20 is installed on the inner top wall of the shell 1 through a coil spring.
[0032] The outer side wall of the rotating shaft 20 is sleeved and fixed with a third gear 19 which is in intermittent engagement with the second gear 18. When the first gear 15 rotates to engage with the second gear 18, the second gear 18 will rotate and move around the circumference of the first gear 15 to engage with the third gear 19.
[0033] The bottom of the rotating shaft 20 is fixed with a swing rod 21 which is perpendicular to the axis of the rotating shaft 20. One end of the swing rod 21 is provided with a protruding block 22. The inner top wall of the shell 1 is provided with a hanging arm 23. The stop block 24 is elastically inserted into the hanging arm 23 in a vertical sliding manner. When the first gear 15 is not engaged with the second gear 18, the protruding block 22 does not press the stop block 24, and the stop block 24 is separated from the outer side of the discharging end of the feeding port 2.
[0034] The baffle 24 is sleeved with a grommet 25 and a second spring outside, and the two ends of the second spring are connected with the outer wall of the grommet and the outer wall of the boom 23 respectively. When the second spring is in a non-deformation state, the baffle 24 is separated from the outside of the discharge end of the feeding port 2.
[0035] The working principle of the embodiment is as follows: The feed is put into the shell 1 through the feeding port 2, and the first paddle rod 4 is driven to rotate by the motor output shaft to stir and mix the feed. During the rotation of the first paddle rod 4, the first limiting block 7 continuously rubs the groove wall of the first limiting groove 6 in the closed loop and the eight-shaped structure, and under the limiting action of the second cylinder 9, the first supporting arm 8 and the through hole, the first cylinder 5 reciprocates in the axial direction of the first paddle rod 4, thereby driving the second supporting arm 13, the scraper 14 and the second paddle rod 10 to reciprocate vertically. This not only scrapes the feed particles adhering to the inner side wall of the shell 1 to the bottom of the shell 1, but also increases the contact range of the feed, thereby improving the mixing efficiency and effect. Meanwhile, the up-and-down reciprocation of the second paddle rod 10 causes the second limiting block 12 thereon to be continuously rubbed and extruded by the groove wall of the second limiting groove 11 in the spiral line shape, so that the second paddle rod 10 not only reciprocates up and down, but also rotates reciprocally, thereby further improving the stirring efficiency and effect.
[0036] In addition, the continuous rotation of the first paddle rod 4 also causes the first gear 15 to intermittently engage with the second gear 18. When the first gear 15 engages with the second gear 18, the second gear 18 not only rotates, but also moves along the rotation direction of the gear teeth area of the first gear 15 to engage with the third gear 19 (the first spring is stretched and deformed) through the third limiting block 17 and the third limiting groove 16, so as to drive the third gear 19, the shaft 20, the swing rod 21 and the lug 22 to rotate (the coil spring is compressed), and make the lug 22 rotate and press the baffle 24, so that the baffle 24 moves to the discharge end of the feeding port 2 to complete the blocking.
[0037] When the first gear 15 rotates and disengages from the second gear 18, the first spring releases the elastic force to push the third limiting block 17 to move reversely in the third limiting groove 16, so as to make the second gear 18 return to the initial position, and the coil spring releases the elastic force to drive the swing rod 21 and the lug 22 to rotate and disengage from the baffle 24 through the shaft 20, and the second spring releases the elastic force to drive the baffle 24 to disengage from the discharge end of the feeding port 2, so as to release the blocking state of the discharge end of the feeding port 2. With the continuous rotation of the first paddle rod 4, the process is repeated, so as to realize the intermittent discharge of the discharge end of the feeding port 2.
[0038] After the mixing is completed, the valve of the discharge port 3 is opened to release the mixed feed.
[0039] The above embodiments are only the preferred embodiments of the present application, and cannot be used to limit the protection scope of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the protection scope of the present application.
