Description

Technical Field

[0001] The utility model relates to the technical field of grain-rough separation screens, in particular to a movable grain-rough separation screen. Background Art

[0002] The rice-brown separator is a vibrating type, characterized by high separation capacity and easy maintenance. It separates the mixture of paddy and brown rice into three types: paddy, a mixture of paddy and brown rice, and brown rice. These are discharged through three different outlets. The paddy returns to the rice huller, while the paddy-brown rice mixture is fed to the separator's feed port. Only the brown rice is fed to the rice mill. This increases the milling repetition rate and reduces broken rice when using a low-pressure rice mill, resulting in the production of pure white rice free of paddy.

[0003] The patent document with publication number CN218637872U discloses a movable grain-rough separation screen. By setting universal wheels at the bottom of the bracket, the entire device can be moved freely, which is convenient for personnel to use. In addition, semicircular rods are provided on the screen, which can make the grain-rough mixture be simply lifted up when it comes into contact with it, so that the impurities in the grain-rough mixture can be sucked into the debris box with the help of the vacuum hose, thereby improving the efficiency of grain-rough separation and improving the work efficiency of the staff.

[0004] However, research has found that the existing rice-rough separation screen has certain disadvantages when used:

[0005] The movable grain-rough separation screen is provided with universal wheels at the bottom of the bracket to ensure the free movement of the entire device. However, in actual use, due to the large size of the equipment, the setting of the universal wheels makes its movement trajectory difficult to control, and multiple people are required to jointly control the movement of the equipment to ensure safety, which is time-consuming and labor-intensive. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, an embodiment of the present application provides a movable grain-rough separation screen, which is achieved by arranging two slides and fixed slide rails and movable slide rails cooperating with the slides between the two sides of the separation screen base frame and the base frame plate, and keeping the fixed slide rails fixed to the base frame plate, while the movable slide rails are movably connected to the inside of the base frame plate. At the same time, by arranging universal wheels at the four corners of the bottom of the base frame plate, the rolling direction of the universal wheels can be limited by means of two fixed seats fixed to the ground, thereby achieving the technical effect of moving the grain-rough separation screen on the top of the separation screen base frame along the horizontal or vertical position and finally adjusting it to the target position.

DETAILED DESCRIPTION

[0027] Example 1:

[0028] A movable rice and rough separation screen, such as Figures 1-4 As shown, it includes a separation screen chassis 1 applied to the rough grain separation screen and a chassis frame plate 5 arranged at the bottom of the separation screen chassis 1, one end of the chassis frame plate 5 is processed with two slideways 12, and a sliding support structure (including a fixed part and an adjustment part, and the distance between the fixed part and the adjustment part can be adjusted) is provided between the bottom of both sides of the separation screen chassis 1 and the top of both sides of the chassis frame plate 5. Angle seats 3 are integrally formed at the four corners of the chassis frame plate 5, and the bottom of the corner seat 3 is assembled and connected with a universal wheel 7. Fixed seats 4 are provided at the bottom of both ends of the chassis frame plate 5.

[0029] The fixed part of the sliding support structure includes a fixed slide rail 11, and the adjustment part of the sliding support structure includes a movable slide rail 2. The bottoms of both sides of the chassis frame plate 5 are processed with slide seats 8. The bottoms of one end of the two movable slide rails 2 are assembled and connected with connecting bars 14 (so that when one movable slide rail 2 moves inside one slide seat 8, it can drive the other movable slide rail 2 to move inside the corresponding slide seat 8). A rectangular groove 15 is processed on the surface of the bottom of the chassis frame plate 5. The two slideways 12 are respectively located on both sides of the chassis frame plate 5, and the two movable slide rails 2 are respectively slidably connected to the inside of the two slideways 12;

[0030] Among them, by making the two fixed slide rails 11 respectively assembled and connected to the top of one end of the bottom frame plate 5 (and respectively located on both sides of the bottom frame plate 5), and making the connecting bar 14 slidably connected to the inside of the two rectangular grooves 15, and blocked by the inner walls at both ends of the rectangular grooves 15, when controlling the movable slide rail 2 to slide inside the fixed slide rail 11, the track composed of the fixed slide rail 11 and the movable slide rail 2 can be extended to support the separation screen chassis 1 to slide on the top of the track through the slide seat 8, so as to meet the requirement of the rough grain separation screen moving a certain distance on the ground;

[0031] At the same time, by making the movable slide rail 2 slide independently of the fixed slide rail 11 inside the slide seat 8, when the slide seat 8 is sleeved on the outside of the fixed slide rail 11 and the movable slide rail 2, the distance between the movable slide rail 2 and the fixed slide rail 11 can be flexibly changed, thereby preventing the fixed slide rail 11 from being exposed from the bottom of the separation screen chassis 1 when not in use;

[0032] Secondly, in order to reduce the resistance of the slide 8 to the movement outside the fixed slide rail 11 and the movable slide rail 2, as shown in FIG. Figure 3 As shown, a plurality of pulleys 10 are provided inside the fixed slide rail 11 and the movable slide rail 2. By making the tops of the plurality of pulleys 10 protrude from the surfaces of the movable slide rail 2 and the fixed slide rail 11, the movable slide rail 2 and the fixed slide rail 11 are slidably connected to the inside of the slide seat 8. When the pulleys 10 are rollingly connected to the top inner wall of the slide seat 8, the resistance of the separation screen chassis 1 between the top of the fixed slide rail 11 and the movable slide rail 2 through the slide seat 8 can be reduced.

[0033] like Figure 1 and Figure 2 As shown, a movable notch 6 is processed inside the fixed seat 4, and the cross-section of the movable notch 6 is an isosceles trapezoid. By fixing the fixed seat 4 to the ground, the two universal wheels 7 at one end of the bottom of the chassis plate 5 are rollingly connected to the inside of the movable notch 6, which can limit the movable trajectory of the universal wheel 7, so that the separation screen chassis 1 can move along a fixed direction through the universal wheel 7 at the bottom of the chassis plate 5, so that the separation screen chassis 1 can move along the X-axis direction on the top of the chassis plate 5 under the support of the sliding support structure, and the two universal wheels 7 at both ends of the bottom of the chassis plate 5 are movably connected to the inside of the two fixed seats 4 respectively, supporting the chassis plate 5 to move along the Y-axis direction on the ground, so as to facilitate the precise control of the position of the rough grain separation screen assembled on the top of the separation screen chassis 1 within a certain range.

[0034] The utility model discloses a movable grain-rough separation screen. Two slide seats 8 and fixed slide rails 11 and movable slide rails 2 cooperating with the slide seats 8 are arranged between the two sides of the separation screen chassis 1 and the chassis frame plate 5. The fixed slide rails 11 are kept fixed to the chassis frame plate 5, while the movable slide rails 2 are movably connected to the inside of the chassis frame plate 5, so as to ensure that the grain-rough separation screen on the top of the separation screen chassis 1 can be moved laterally by a fixed distance.

[0035] At the same time, by arranging universal wheels 7 at the four corners of the bottom of the chassis plate 5, the rolling direction of the universal wheels 7 can be limited by means of two fixed seats 4 fixed on the ground, which is conducive to ensuring that the rough rice separation screen on the top of the separation screen chassis 1 moves longitudinally for a certain distance without affecting the four universal wheels 7 supporting the chassis plate 5 and the separation screen chassis 1 for long-distance transfer on the ground.

[0036] Example 2:

[0037] On the basis of Example 1, Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, this embodiment is a limiting structure 9 of the movable slide rail 2. One end of each of the two movable slide rails 2 is provided with a limiting structure 9. The limiting structure 9 includes a support seat 903. The support seat 903 is internally threadedly connected to a threaded rod 901. One end of the threaded rod 901 is processed with a control ring 902. A receiving notch 13 is processed inside one end of the movable slide rail 2. One end of the threaded rod 901 is threadedly connected to a pressure plate 904.

[0038] The support seat 903 is hinged to the inner wall of one end of the receiving slot 13. By controlling the control ring 902 to drive the threaded rod 901 to rotate in the horizontal direction, the threaded connection between the threaded rod 901 and the support seat 903 is adjusted. When the surface of the pressure plate 904 applies pressure to the inner wall of one end of the receiving slot 13, the threaded rod 901 and the control ring 902 are kept in a horizontal state, which facilitates the user to control the sliding of the movable slide rail 2 inside the slide seat 8, thereby extending or withdrawing the movable slide rail 2.

[0039] At the same time, by controlling the control ring 902 to drive the threaded rod 901 to rotate in the vertical direction, adjusting the threaded connection between it and the support seat 903, the surface of the pressure plate 904 applies pressure to the ground. After controlling the movable slide rail 2 to slide out from the inside of the slide seat 8, the pressure plate 904 at one end of the threaded rod 901 applies pressure to the ground. Based on the influence of friction, the movable slide rail 2 is prevented from continuing to slide inside the slide seat 8. With the help of reverse force, it is difficult for the slide seat 8 to slide outside the movable slide rail 2 and the fixed slide rail 11, that is, the separation screen chassis 1 is difficult to move relative to the chassis frame plate 5, thereby fixing the separation screen at the bottom of the separation screen chassis 1 to the target area;

[0040] In addition, by controlling the control ring 902 to drive the threaded rod 901 to rotate in the vertical direction and adjusting the threaded connection between it and the support seat 903, the pressure plate 904 applies pressure to the bottom surface of the separation screen chassis 1, which can limit the movement of the movable slide rail 2 relative to the slide seat 8, thereby retracting the movable slide rail 2 into the interior of the slide seat 8.

[0041] The present invention provides a movable grain separation screen by providing a limiting structure 9 composed of a threaded rod 901, a control ring 902, a support seat 903 and a pressure plate 904 at one end of a movable slide rail 2 (located inside a receiving notch 13, and the receiving notch 13 is processed to one end of the movable slide rail 2). The control ring 902 is used to adjust the threaded connection between the threaded rod 901 and the support seat 903. When the threaded rod 901 is in a horizontal state and the surface of the pressure plate 904 is pressed against the inner wall of one end of the receiving notch 13, a control point is provided for the user to drag the movable slide rail 2 to slide inside the slide seat 8.

[0042] At the same time, when the threaded rod 901 is in a vertical state and the pressure plate 904 is applied to the ground, the movable slide rail 2 can slide out from the inside of the slide seat 8 by means of the cooperation of the threaded rod 901, the pressure plate 904 and the movable slide rail 2 to increase the friction between the movable slide rail 2 and the slide seat 8 and the resistance of the base frame plate 5 to the movement of the ground, so as to facilitate fixing the separation screen base frame 1 and the base frame plate 5 to the ground, and when the movable slide rail 2 is in a state of being completely retracted into the slide seat 8, the pressure plate 904 is applied to the bottom surface of the separation screen base frame 1, which can limit the movable slide rail 2 from automatically sliding out of the inside of the slide seat 8.

[0043] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
