Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1 , the vibrating screen transmission component of the beach garbage cleaning vehicle provided in this embodiment includes: a power unit 1 , a crank-rocker mechanism 2 and a vibrating screen mesh 3 ;

The power device 1 is used to provide power for the crank-rocker mechanism 2;

The crank-rocker mechanism 2 is used to drive the vibrating screen 3 to periodically reciprocate;

The vibrating screen 3 is used to separate garbage and sand and transfer the garbage to the beach garbage cleaning vehicle.

In this embodiment, the power device 1 is used to make the crank-rocker mechanism 2 drive the vibrating screen 3 to reciprocate periodically. During the periodical reciprocating motion of the vibrating screen 3, not only can the garbage and sand be separated, but also the garbage can be transferred to the beach garbage cleaning vehicle. Therefore, there is no need to rely on manual cleaning for garbage on the beach. The invention can be used for daily beach cleaning work, improves cleaning efficiency, and meets daily beach cleaning needs.

The transmission component described in this embodiment further includes:

The shovel plate 4 is used to transfer the mixture of garbage and sand to the vibrating screen 3;

The shovel plate 4 is connected to one end of the vibrating screen 3 .

The vibrating screen 3 is evenly distributed with through holes;

When the vibrating screen 3 reciprocates periodically, the sand flows out from the through holes.

The vibrating screen 3 is stepped; the included angle between the two planes of each step and the vertical plane is an acute angle;

When the vibrating screen 3 reciprocates periodically, the garbage moves from one end of the vibrating screen 3 to the other end;

The other end of the vibrating screen 3 is communicated with the interior of the beach garbage cleaning vehicle.

The conveying member described in this embodiment is installed at the entrance of the beach garbage cleaning vehicle. When the cleaning vehicle moves forward on the beach, the shovel plate 4 shovels the mixture of garbage and sand into it. Since the cleaning vehicle does not stop, the mixture will be shoveled into the vibrating screen 3 . There are through holes evenly distributed on the vibrating screen 3, and the through holes can allow the sand to pass through, so that when the vibrating screen 3 moves to generate vibration, the sand will pass through the through holes and flow out from the vibrating screen 3. , so as to achieve the effect of separating garbage and sand.

In this embodiment, the vibrating screen 3 is designed in a stepped shape, and the included angle between the two planes of each step and the vertical plane is an acute angle. In general, the inlet ratio of the cleaning vehicle is higher than the shovel plate 4, so there is a process of "climbing" in garbage transportation. If each layer of steps is set as a right-angle step, since the contact surface between the garbage and the vibrating screen 3 is a plane, then during the reciprocating motion of the vibrating screen 3, the garbage may fall into the shovel plate 4 again, and the unreachable to the "climbing" effect. At present, in practical application, the entrance of the cleaning vehicle cannot be much higher than the shovel plate 4, and the angle between the inclined plane where the steps of the vibrating screen 3 are located and the horizontal plane can be kept less than 45 degrees.

As shown in FIGS. 1 to 3 , in this embodiment, the vibrating screen mesh 3 is stepped and has a triangular wave shape. Since the entrance of the cleaning vehicle is higher than the shovel plate 4, the vibrating screen 3 is of low order near the shovel plate 4, and is of high order near the entrance of the cleaning vehicle. When the vibrating screen 3 performs periodic reciprocating motion, due to the action of inertia, the garbage will move from a low order to a high order on the vibrating screen 3, thereby automatically entering the entrance of the cleaning vehicle.

As shown in Figures 1 and 2, the crank-rocker mechanism 2 includes: a crank 21, a rocker 22 and a main connecting rod 23;

The crank 21 is connected to the output end of the power device 1;

One end of the rocker 22 is hinged with the crank 21, and the other end is movably pinned to one end of the main connecting rod 23;

The other end of the main link 23 is connected with the vibrating screen 3;

The middle part of the main link 23 is provided with a first fulcrum fixed with the beach garbage cleaning vehicle.

The crank-rocker mechanism 2 further includes: a slave connecting rod 24;

One end of the slave connecting rod 24 is provided with a second fulcrum fixed to the beach garbage cleaning vehicle, and the other end is connected to the vibrating screen 3 .

There are two cranks 21, which are respectively arranged on both sides of the power unit 1;

There are two rockers 22, corresponding to one crank 21 respectively;

In this embodiment, the crank 21 is a circular turntable. One end of the rocker 22 is hinged to the corresponding crank 21 through a Z-shaped connecting piece.

There are two main connecting rods 23, respectively corresponding to one rocker 22;

The output ends of the power device 1 are respectively connected with the two cranks 21 to ensure that the two cranks 21 rotate synchronously;

The two rockers 22 are respectively sleeved on a push shaft 25, and the two ends of the push shaft 25 are respectively connected with one end of the two main links 23;

In this embodiment, the other end of the rocker 22 is sleeved on the same push shaft 25 . When the two cranks 21 rotate synchronously, the corresponding rockers 22 are driven to move synchronously, so that the two rockers 22 push the push shaft 25 at the same time.

The first fulcrum is realized by the first support shaft 26:

The middle parts of the two main links 23 are respectively passed through by a first support shaft 26, and both ends of the first support shaft 26 are respectively fixed and installed on the beach garbage cleaning vehicle;

The other ends of the two main links 23 are respectively installed on both sides of one end of the vibrating screen 3 .

The second fulcrum is realized by the second support shaft 27:

There are two slave connecting rods 24; one end of the two slave connecting rods 24 is respectively passed through a second support shaft 27, and both ends of the second support shaft 27 are respectively fixed and installed on the beach garbage cleaning vehicle;

The other ends of the two slave connecting rods 24 are respectively installed on both sides of the other end of the vibrating screen 3 .

A support plate 5 is installed vertically on both sides of the vibrating screen 3 respectively;

The other ends of the two main links 23 pass through a first fixing rod 28 respectively, and the movable pins are connected to the corresponding support plate 5;

The other ends of the two slave connecting rods 24 pass through a second fixing rod 29 respectively, and the movable pins are connected to the corresponding supporting plates 5 .

In this embodiment, the function of the two support plates 5 is to ensure that the garbage will not fall out from both sides of the vibrating screen 3 when moving. The function of the first fixed rod 28 and the second fixed rod 29 is to make the two main links 23 more stable when driving the vibrating screen 3 .

The vibrating screen 3 periodically reciprocates along the slope to which the steps belong. The slope to which the step belongs is the slope formed by connecting the vertices of the vibrating screen 3 .

As shown in FIG. 3 , in this embodiment, one end of the vibrating screen mesh 3 is low and the other end is high. The power device 1 can be a bidirectional DC motor, the output end of which is connected to two cranks 21 . The two cranks 21 rotate synchronously, driving the rocker 22 to push and pull the push shaft 25 synchronously. When the two rockers 22 push one end of the two main links 23 to the left at the same time, due to the action of the first support shaft 26, the other ends of the two main links 23 move to the upper right direction; thereby driving the two support plates 5 and the vibrating screen 3 also move upward to the right; the two slave connecting rods 24 are linked accordingly. When the two rockers 22 pull one end of the two main links 23 to the right at the same time, due to the action of the first support shaft 26, the other ends of the two main links 23 move to the lower left direction; thereby driving the two support plates 5 and the vibrating screen 3 also move to the lower left direction; the two slave connecting rods 24 are linked accordingly.

The garbage on the vibrating screen 3 is stuck between the triangular steps. When the vibrating screen 3 moves to the upper right, the contact surface between the triangular step and the left side of the garbage will give the garbage a thrust in the upper right direction, pushing the garbage to move upward to the right. ; When the vibrating screen 3 moves to the lower left, because the garbage just receives the thrust in the upper right direction, plus the effect of inertia, the garbage moves up to the right to achieve the effect of "climbing".

In this embodiment, the device dimensions are shown in Table 1:

Table 1

The length of the vibrating screen 3 is L ₁ , the width is L ₂ , the length of the swing rod is L ₃ , and the radius of the crank 21 is r ₁ . The length and width of the vibrating screen 3 are mainly determined by the size of the cleaning vehicle. In this calculation, 1.5m is used. Take a long clean-up car as an example. The swing rod is the length of the main link 23 from the intersection with the first support shaft 26 to the other end, which is equal to the length of the secondary link 24 .

The linear swing of the vibrating screen 3 is simplified as linear vibration, the vibration amplitude is 2r ₁ , the vibrating screen 3 is at the rightmost position as the initial value, the radius of the crank 21 is r ₁ , and the motion of the vibrating screen 3 is r 1 . The equation is:

x=r(1-cosα)+rμ(1-cos2α)/4 (1)

y=r sinα (2)

V _x =rωsinα+rωμsinα/2 (3)

In the formula, x is the horizontal displacement of the vibrating screen, α is the crank angle, μ is the ratio of the crank radius to the connecting rod length, y is the vertical displacement of the vibrating screen, V _x is the speed of the vibrating screen, ω is the crank angular velocity. According to the above formulas (1) to (3), it can be known that the radius and rotation angle of the crank 21 are the main factors affecting the displacement and speed of the vibrating screen 3 .

When the device is used for cleaning machinery, it adapts to the environmental characteristics of different places based on the different types of materials to be cleaned. For example, when cleaning the beach, most of the cleaning objects are a mixture of sand and kitchen waste, which can be filtered through a vibrating screen. The filtration of the net 3 separates garbage and sand. When working on the road, garbage such as branches and plastics occupies a large share. Therefore, through the force analysis of the garbage on the vibrating screen 3, parameters such as the size of the crank 21 and the inclination of the screen are calculated.

When working on the beach, the screening efficiency of the device and the garbage collection rate are the main performance evaluation indicators. The screening efficiency formula is:

In the formula, m ₁ is the weight of the garbage transferred from the vibrating screen to the garbage bin, and m ₂ is the weight of the garbage on the vibrating screen.

According to statistical data, plastics are the most (37.37%), followed by foams (35.67%); the total density is 15.91g/m2, and the density of plastics (3.62g/m2) is the largest, followed by fabrics (cloths) (2.87g/m2) and wood products (1.97g/m2); the main sources are domestic waste and tourist waste, accounting for 39.26% and 25.23% of the total waste respectively. According to the analysis of plastics and foams, the plastics are taken as an example of a plastic rectangular block with a length of 30mm, a width of 20mm, and a height of 20mm. According to the structure, shape and size of the garbage and the size of the sand particles, the final result is that the sieve aperture is 2mm.
