DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0033] like Figure 1-Figure 9 As shown, a multi-stage crushing device for tail vegetable silage proposed in one embodiment of the present application includes:

[0034] A carrier frame 1 is provided on which a feed box 2 is installed. Two rotating rods 3 are rotatably installed in the feed box 2. A plurality of crushing blades 4 are installed on the rotating rods 3 for crushing the tail vegetables. Specifically, a motor is installed on the feed box 2. A gear is installed between the two transmission rods 50521, and the two gears are meshed, which is similar to the existing crusher structure. The motor output shaft is connected to one of the rotating rods 3.

[0035] The squeezing mechanism 5 comprises a collecting cover 501 installed below the feed box 2, a squeezing cylinder 502 is installed on the carrier frame 1, the collecting cover 501 is located above the squeezing cylinder 502 and is connected to the squeezing cylinder 502, a discharge trough 503 is provided at the bottom of the squeezing cylinder 502, a plugging member 504 for plugging the discharge trough 503 is installed on the squeezing cylinder 502, and a conveyor can be provided below the discharge trough 503 during specific use to collect the crushed waste vegetables, an extruding member 505 is installed in the squeezing cylinder 502, and the extruding member 505 is used to squeeze the waste vegetables in the squeezing cylinder 502, and a plurality of drainage grooves 506 are provided on the squeezing cylinder 502;

[0036] The conveying mechanism 6 is installed on the supporting frame 1 and acts on the pressing cylinder 502 and the feed box 2. After the waste vegetables inside the pressing cylinder 502 are squeezed by the extruder 505, the waste vegetables in the pressing cylinder 502 are conveyed to the feed box 2 through the conveying mechanism 6.

[0037] When in use, the motor is started to drive one of the rotating rods 3 to rotate, and the gears installed on the rotating rods 3 further realize the rotation of the crushing blades 4 on the two rotating rods 3. At this time, the tailings can be poured into the feed box 2 to achieve preliminary crushing of the tailings. After crushing, the tailings will enter the collecting cover 501, and then enter the pressing cylinder 502 through the action of gravity. At this time, the tailings in the pressing cylinder 502 can be squeezed by the extrusion piece 505. After being squeezed, the excess water of the tailings in the pressing cylinder 502 will be discharged from the multiple drainage grooves 506. The subsequent tailings are transported to the feed box 2 through the conveying mechanism 6 for crushing again, thereby achieving multiple crushing, ensuring the uniformity of the tailings crushing, and indirectly reducing the workload of the staff.

[0038] like Figure 1-Figure 4As shown, in some embodiments, the extrusion member 505 includes an extrusion cover 5051 installed on the carrier 1, the extrusion cover 5051 is connected to one end of the pressing cylinder 502, and an extrusion plate 5053 is horizontally slidably installed in the extrusion cover 5051, which is used to block the connection between the extrusion cover 5051 and the pressing cylinder 502, and an elastic resistance member 5052 for providing elastic force to the extrusion plate 5053 is installed on the extrusion cover 5051. The conveying mechanism 6 is used to convey the tail vegetables in the extrusion cover 5051, and the carrier 1 is installed with a pressure component 7 for increasing the internal pressure of the pressing cylinder 502. That is to say, the tail vegetables are crushed after passing through the feed box 2 and enter the pressing cylinder 502. When the squeezing cylinder 502 is inside, the pressure-applying assembly 7 is used to increase the internal pressure of the squeezing cylinder 502, thereby conveying the tailings in the pressure-applying cylinder to the extrusion plate 5053. The tailings are compressed due to the pressure, thereby squeezing out the water in the tailings and flowing out from the drainage groove 506. When the pressure applied to the squeezing plate 5053 is greater than the elastic force provided by the elastic resistance member 5052, the squeezing plate 5053 will move away from the squeezing cylinder 502, thereby allowing part of the tailings to enter the extrusion cover 5051. At this time, the tailings in the extrusion cover 5051 are conveyed to the feed box 2 through the conveying mechanism 6 for further crushing.

[0039] like Figure 1-Figure 4 and Figure 8 As shown, in some embodiments, the elastic resistance member 5052 includes a transmission rod 50521 horizontally mounted on the extrusion plate 5053, the free end of the transmission rod 50521 passes through the extrusion cover 5051 and is located outside, and a resistance plate 50522 is arranged at the position where the transmission rod 50521 is located outside, a connecting tube 50523 is vertically mounted on the carrier frame 1, and a column 50524 with one end in an outer arc shape is vertically slidably inserted at the top of the connecting tube 50523, a resistance spring 50529 is installed between the column 50524 and the connecting tube 50523, and a resistance spring 50529 is arranged on the resistance plate 50522 for contacting with the outer arc of the column 50524. The forcing inclined surface 50525 is in contact with the extrusion plate 5053. In this embodiment, when the extrusion plate 5053 is subjected to pressure, the movement of the extrusion plate 5053 will cause the resistance plate 50522 to move. Because the forcing inclined surface 50525 on the resistance plate 50522 is in contact with the column 50524, the column 50524 will move downward when the resistance plate 50522 moves, thereby compressing the resistance spring 50529. When the force applied to the extrusion plate 5053 is less than the elastic force of the resistance spring 50529, the resistance spring 50529 will drive the column 50524 to move upward, thereby causing the extrusion plate 5053 to move and reset.

[0040] like Figure 1-Figure 9As shown, in some embodiments, the pressure-applying assembly 7 includes an air pump 701 mounted on the carrier 1, and the air outlet end of the air pump 701 is connected to an air inlet pipe 702, and the free end of the air inlet pipe 702 is connected to an end of the pressing cylinder 502 away from the extrusion plate 5053, and the conveying mechanism 6 includes an arc-shaped cover plate connected to one side of the feed box 2, and the free end of the arc-shaped cover plate is connected to the top of the extrusion cover 5051, and the top of the extrusion plate 5053 is horizontally structured with a baffle plate 10 for blocking the connection between the arc-shaped cover plate and the extrusion cover 5051, and the baffle plate 10 effectively prevents the tail food in the extrusion cover 5051 from entering the arc-shaped cover plate when the extrusion plate 5053 is not moving quickly. Specifically, when the extrusion plate 5053 moves to below the bottom end of the arc-shaped cover plate, the extrusion plate 5053 will quickly move like Figure 4 As shown, it moves to the right, and gas is delivered to the air inlet pipe 702 through the air pump 701, so that the air inlet pipe 702 delivers gas to the pressing cylinder 502. When the extrusion plate 5053 blocks the connection between the extrusion cover 5051 and the pressing cylinder 502, the tail vegetables in the pressing cylinder 502 are blown toward the extrusion cover 5051 by the airflow, so that the tail vegetables are squeezed on the extrusion plate 5053, and the air is blown into the outside through the drainage groove 506. The drainage groove 506 has a small groove diameter, which is enough to prevent the tail vegetables in the pressing cylinder 502 from flowing out. As the tail vegetables continue to increase, multiple drainage grooves 506 will be blocked by the tail vegetables. At this time, the continuous delivery of gas will increase the air pressure inside the pressing cylinder 502, so that the extrusion plate 5053 can cooperate with the The function of squeezing the tailings inside the pressing cylinder 502 is realized so that the moisture of the tailings is discharged from the drainage groove 506 until the air pressure inside the pressing cylinder 502 is greater than the elastic force of the resistance spring 50529. At this time, the tailings inside the pressing cylinder 502 are pushed into the arc cover plate by the action of the airflow, and then enter into the feed box 2, so that no additional driving force is required to transport the tailings in the extrusion cover 5051 to the feed box 2. Moreover, the method of conveying gas into the pressing cylinder 502 by the air pump 701 can further improve the effect of squeezing out the moisture of the tailings. After the mixing and crushing, the tailings will be squeezed to remove part of the moisture, which can reduce the workflow of the process and is more convenient to use.

[0041] like Figure 4 and Figure 8As shown, in some embodiments, the contact plate 50522 is U-shaped and horizontally slidably sleeved on the transmission rod 50521, the number of the forced inclined surfaces 50525 is two and symmetrically distributed on the contact plate 50522, the transmission rod 50521 is located between the opposite surfaces of the contact plate 50522 and is configured with a first convex ring 50526, a first spring 50527 is installed between the first convex ring 50526 and the contact plate 50522, and the transmission rod 50521 is configured with a second convex ring 505210 near its free end. A second spring 50528 is installed between the contact plate 50522, and the elastic force of the contact spring 50529 is greater than the elastic force of the first spring 50527 and the second spring 50528. A return member 8 for driving the transmission rod 50521 to return to its original position is installed on the extrusion cover 5051. In this embodiment, the contact plate 50522 is slidable. When the extrusion plate 5053 blocks the connection between the extrusion cover 5051 and the pressing cylinder 502, the extrusion plate 5053 is at the end at the maximum limit, and the column rod 50524 is at the contact plate 50522. Figure 4As shown in the figure, the first spring 50527 and the second spring 50528 are in an uncompressed state. When the extrusion plate 5053 moves to the right under pressure, the first spring 50527 will be compressed and the second spring 50528 will be stretched. As the extrusion plate 5053 continues to move, the column rod 50524 will move downward to break away from the right-side forcing inclined surface 50525 and contact the bottom surface of the contact plate 50522. At this time, the first spring 50527 and the second spring 50528 will quickly reset due to their own elastic deformation characteristics, thereby providing the contact plate 50522 with elastic power to move to the right. As the contact plate 50522 moves, it will pull the transmission rod 50521 to move together, so that the extrusion plate 5053 will quickly move a distance to the right. Therefore, when the internal pressure of the pressing cylinder 502 reaches a certain level, the extrusion plate 5053 will quickly move a distance to the right to make the pressing cylinder 502 The pressure in the cylinder 502 is quickly released, thereby generating an impact force to quickly push the tail vegetables in the extrusion cover 5051 into the arc cover plate and into the feed box 2. At this time, the extrusion plate 5053 will move to the maximum limit position at the other end, and the column rod 50524 will resist the forcing inclined surface 50525 on the left side of the resistance plate 50522 as shown in the figure. After the internal pressure of the squeezing cylinder 502 is released, the driving force is provided to the transmission rod 50521 through the return member 8. When the transmission rod 50521 moves a certain distance to the left under the driving force, the first spring 50527 and the second spring 50528 will make the transmission rod 50521 move a short distance and then quickly move to the left to reset. The internal pressure of the squeezing cylinder 502 can be quickly released when it reaches a certain threshold, thereby ensuring that the tail vegetables in the extrusion cover 5051 can be quickly transported to the feed box 2, effectively preventing excessive tail vegetables from accumulating in the arc cover plate and causing blockage.

[0042] like Figure 1-Figure 4 As shown, in some embodiments, the homing member 8 includes a first elastic telescopic rod 801 horizontally mounted on the extrusion cover 5051, and the free end of the first elastic telescopic rod 801 is configured with a pushing frame 802. The support frame 1 is provided with a driving assembly 9 acting on the pushing frame 802. When the free end of the transmission rod 50521 contacts the pushing frame 802, the driving assembly 9 provides a driving force to the pushing frame 802 in the direction close to the extrusion plate 5053. That is to say, when the transmission rod 50521 is as Figure 4 After the rapid movement to the right as shown, one end of the transmission rod 50521 will contact the pushing frame 802. At this time, the driving component 9 can provide a driving force to the pushing frame 802 in the direction close to the extrusion plate 5053, thereby pushing the transmission rod 50521 to move a short distance to achieve the resetting of the extrusion plate 5053.

[0043] like Figure 2As shown, in some embodiments, the driving assembly 9 includes two driving rods 901 rotatably mounted on the carrier frame 1, the two driving rods 901 are distributed up and down and are both equipped with a transmission wheel 902, a transmission belt 903 is installed between the two transmission wheels 902, and a plurality of wedge plates 904 are installed in a circular array on the outer peripheral side of the transmission belt 903, and the pushing frame 802 is used to contact the inclined surface of the wedge plate 904, one of the driving rods 901 is connected to one of the rotating rods 3, that is, in the process of the crushing blade 4 rotating to crush the tail vegetables, the driving wheel 902 will also rotate, thereby causing the transmission belt 903 to move continuously, and the transmission belt 903 moves continuously to cause the wedge plate 904 to move continuously, and the inclined surface of the wedge plate 904 contacts the pushing frame 802 and cooperates with the first elastic telescopic rod 801 to cause the pushing frame 802 to reciprocate regularly, so that no additional driving force is required to drive the movement of the pushing frame 802, which is more convenient to use.

[0044] like Figure 2-Figure 6 As shown, in some embodiments, the pushing frame 802 includes a moving frame 8021 horizontally slidably mounted on the carrier frame 1, an executing frame plate 8022 is horizontally slidably mounted on the pushing frame 802, a connecting rod 8023 is hinged on the executing frame plate 8022, and the free end of the connecting rod 8023 is hinged at the bottom of the transmission rod 50521 near its free end, the first elastic telescopic rod 801 is connected to the moving frame 8021, and a forcing sleeve rod 8024 for contacting the inclined surface of the wedge plate 904 is horizontally slidably sleeved on the executing frame plate 8022, and a connecting spring 8025 is installed between the forcing sleeve rod 8024 and the executing frame plate 8022. In this embodiment, the forcing sleeve rod 8024 cannot contact the inclined surface of the wedge plate 904 in normal state. When the transmission rod 50521 is as shown in FIG. Figure 4 As shown in the figure, when it moves quickly to the right, the movement of the transmission rod 50521 will drive the execution frame 8022 to move through the connecting rod 8023, and the execution frame 8022 will drive the forced sleeve rod 8024 to move horizontally when moving. As the forced sleeve rod 8024 moves, the inclined surface of the wedge plate 904 can contact the forced sleeve rod 8024. Specifically, because the wedge plate 904 is continuously moving, when the forced sleeve rod 8024 moves horizontally, the free end of the forced sleeve rod 8024 may just hit the plane on one side of the wedge plate 904. At this time, the connecting spring 8025 will be compressed, and as the wedge plate 904 continues to move, the forcing rod 8024 will be separated from the side plane of the wedge plate 904 and move and reset under the action of the connecting spring 8025, thereby forcing the rod 8024 to move between the two wedge plates 904, thereby ensuring that the inclined surface of the wedge plate 904 can contact the forcing rod 8024, effectively preventing the forcing rod 8024 from rigidly contacting the side plane of the wedge plate 904, resulting in the forcing rod 8024 being unable to smoothly contact the wedge plate 904.

[0045] like Figure 4 and Figure 7 As shown, in some embodiments, the blocking member 504 includes an arc-shaped blocking plate 5041 horizontally slidably sleeved on the pressing cylinder 502, which is used to block the discharge trough 503, a piston cylinder 5042 is installed on the supporting frame 1, a piston rod 5043 is slidably inserted at the free end of the piston cylinder 5042, the free end of the piston rod 5043 is connected to the arc-shaped blocking plate 5041, a second elastic telescopic rod 5044 is installed between the arc-shaped blocking plate 5041 and the supporting frame 1, a connecting pipe 5045 is connected between the piston cylinder 5042 and the air inlet pipe 702, and a three-way solenoid valve 5046 is installed at the connection between the connecting pipe 5045 and the air inlet pipe 702. That is to say, after the crushing and squeezing of the tail vegetables are completed, the three-way solenoid valve 5046 can be used to open the connecting pipe 5045 and the air inlet pipe 702. Valve 5046 makes the air inlet pipe 702 not connected with the pressing cylinder 502, but makes the air inlet pipe 702 connected with the connecting pipe 5045, which will push the piston rod 5043 to move. When the piston rod 5043 moves, it will drive the arc blocking plate 5041 to move, so that the arc blocking plate 5041 no longer blocks the discharge trough 503. Specifically, a pressure relief valve is installed on the piston cylinder 5042. When the air inlet pipe 702 is not connected with the connecting pipe 5045 through the three-way solenoid valve 5046, the second elastic telescopic rod 5044 cooperates with the pressure relief valve to realize the movement and reset of the arc blocking plate 5041 to re-block the discharge trough 503, thereby eliminating the need for additional electricity or manual drive to move the arc blocking plate 5041, making it more convenient to use.

[0046] like Figure 4 and Fig. 9 As shown, in some embodiments, an annular sleeve 11 is installed on the supporting frame 1 and is sleeved on the pressing cylinder 502. A slot 12 is provided at the bottom of the annular sleeve 11, and an arc-shaped through slot 13 is provided at the free end of the annular sleeve 11 for the arc-shaped blocking plate 5041 to pass through. A plurality of drainage grooves 506 are evenly distributed on the outer peripheral side of the pressing cylinder 502 and are located between the extrusion cover 5051 and the collecting cover 501. The design of the annular sleeve 11 effectively prevents liquid from splashing out of the drainage groove 506, plays a guiding role, and ensures a clean working environment.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application.
