Description

Technical Field

[0001] This invention belongs to the field of sewage treatment technology, specifically relating to a weld-free sewage board assembly. Background Technology

[0002] Poultry farming produces a large amount of manure (which is a good type of farmyard manure), but it cannot be directly applied to crops. If manure is applied directly to the soil, it will ferment and generate a lot of heat under suitable conditions, which will burn the roots of crops. At the same time, manure itself carries a large number of bacteria, which can also pose a risk of disease to crops. Therefore, manure needs to be treated to render it harmless before it can be used as plant fertilizer for recycling. That is, poultry manure needs to be collected and dried using air-drying equipment to remove the moisture from the manure so that it can be used effectively.

[0003] Currently, when drying poultry manure, the collected manure is placed on a manure board and a drying device is installed on one side of the manure board (the high-speed airflow blown by the drying device dries the manure on the manure board). In the above process, the manure on the surface can achieve the drying effect under the action of the wind, but the manure in the lower layer (close to the bottom wall of the manure board) hardly comes into contact with the wind, resulting in poor drying effect in this area.

[0004] In addition, most existing manure boards are formed by combining various components and welding them together. When they need to be cleaned after a period of use, their large overall size makes it impossible to disassemble and clean each part separately, resulting in inconvenience and poor cleaning effect. Moreover, because they are formed by welding, after long-term use (soaking in manure water), the welded parts will rust, which will reduce the structural stability and make the welded parts prone to deformation.

[0005] In view of the above, this application provides a weld-free manure board assembly to solve the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a weld-free manure board assembly, which can disassemble and clean each component of the manure board when needed, thereby improving cleaning efficiency and cleaning effect. The efficiency of drying manure on the manure board is improved by providing an air guide channel composed of several arc plates on the arc plate.

[0007] The beneficial effects of the above technical solution are as follows:

[0008] (1) The manure board in this solution is assembled and disassembled in a convenient way. When needed, the various parts on it can be disassembled and cleaned separately, which improves the cleaning efficiency and cleaning effect, avoids welding deformation and makes later maintenance convenient.

[0009] (2) In this scheme, by setting an air guide channel composed of several arc plates on the arc plate, the movement path of the airflow is adjusted, so that the contact time between the airflow and the feces on the feces plate is increased during the process of the airflow passing through the feces plate, thereby improving the drying efficiency of the feces on the feces plate.

[0010] (3) When the guide wheel on the manure board is disengaged from the guide rail and rotates from the horizontal state to the vertical state, the moving gear and the fixed gear can drive the striking ball to strike the manure board, thereby generating vibration so that the feces on the manure board can be better separated from the manure board and avoid the feces from adhering to the manure board (keeping the manure board clean during use).

[0011] (4) When the guide wheel on the manure board is disengaged from the guide rail and rotates from the horizontal state to the vertical state, the airflow is guided by several arc plates and blows from top to bottom across the surface of the manure board. Thus, the rapidly moving airflow can be used to clean the fecal residue attached to the surface of the manure board (further improving the cleaning effect of the manure board).

[0021] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 9 As will be clearly shown in the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all with reference to the accompanying drawings.

[0022] Example 1: This example provides a weld-free manure board assembly 1, as shown in the attached... Figure 1 As shown, including manure board 1, the improvement of this solution is as follows:

[0023] The manure plate 1 has high-density ventilation holes 21, and nylon plugs 12 are detachably installed at both ends of the longitudinal direction of the manure plate 1. Guide wheels 13 are rotatably installed on the same side of both nylon plugs 12, and axle pins 14 are installed on the other side. Several spaced arc-shaped plates 22 are installed on one longitudinal side of the manure plate 1, and an air guide channel is formed between two adjacent arc-shaped plates 22. The manure plate 1 also includes two drive chains 2 (as shown in the attached diagram) located on both sides of the longitudinal direction of the manure plate 1. Figure 3 As shown, the manure plate 1 is located between the drive chains 2 on both sides, as attached. Figure 6 As shown, the drive chain 2 is fitted with a drive wheel, and the drive wheel is mounted on the frame (the frame is not shown in the figure). On the frame located between the drive chains 2 on both sides of the manure plate 1 longitudinally, the manure plate 1 is provided with guide rails 23 arranged along the length of the frame (as shown in the attached figure). Figure 6 As shown, there are a total of 4 guide rails 23, that is, the upper manure plate 1 corresponds to two guide rails 23, and the lower manure plate 1 corresponds to two guide rails 23. The shaft pins 14 on both sides of the longitudinal direction of the manure plate 1 are rotatably mounted on the inner wall of the drive chain 2 (that is, on the opposite side wall of the two drive chains 2). When the drive chain 2 drives the manure plate 1 to move, the guide wheel 13 mounted on the nylon plug 12 just presses on the corresponding guide rail 23 (the setting of the guide wheel 13 and the guide rail 23 allows the manure plate 1 to move easily with the drive chain 2). In this embodiment, the process is as follows:

[0024] As attached Figure 6 As shown, the manure to be dried can be placed on the manure plate 1, and the manure plate 1 moves at a certain speed as the drive chain 2 rotates (along...). Figure 6 (The arrow in the diagram points to the movement). At this time, a drying component (such as a fan, not shown in the diagram) is provided on one side of the frame, which generates a high-speed airflow (the direction of the high-speed airflow is perpendicular to the direction in which the manure plate 1 moves with the drive chain 2). The high-speed airflow blows across the manure plate 1, thereby drying the manure placed on the manure plate 1, as shown in the attached diagram. Figure 6As shown, under the action of the drive chain 2 and the drive wheel, the manure plate 1 is divided into an upper manure plate 1 and a lower manure plate 1. When the upper manure plate 1 moves to point A with the drive chain 2, the guide wheel 13, which is rotated and mounted on the nylon plug 12, no longer contacts the guide rail 23 (the length of the guide rail is h, so that when the manure plate 1 moves with the drive chain 2 to near point A or to point B, the guide wheel 13 no longer contacts the guide rail 23). This causes the manure plate 1 to begin to rotate relative to the drive chain 2 (the manure plate 1 is rotated and mounted on the wall of the drive chain 2 via the shaft pin 14), that is, as shown in the attached diagram. Figure 6 The manure plate 1 is located at point A. At this time, the manure on the manure plate 1 slides down to the lower manure plate 1 and continues to move with the drive chain 2 until it reaches the discharge point. At this time, the guide wheel 13 on the manure plate 1 disengages from the guide rail 23 again, thereby realizing the tilting of the manure plate 1 (the tilted material is collected or transferred back to the feeding point for circulation and drying until the requirements are met).

[0025] Note: Manure plate 1 moves from point A to the lower layer along the drive chain 2 and eventually reaches a horizontal state. A guide plate (arc-shaped and docking with the lower guide rail 23, not shown in the figure) is located on the left side of the frame to guide the vertical manure plate 1 back to a horizontal state as the drive chain 2 moves (since this is not the improvement point of this solution, its structure will not be described in detail). As manure plate 1 moves with the drive chain 2, high-speed airflow blows across the area above the upper manure plate 1, the area between the upper and lower manure plates 1, and the area below the lower manure plate 1, thereby drying the manure accumulated on the manure plate 1 (the high-speed airflow carries away the internal moisture from the surface of the manure). See attached... Figure 5 As shown, this is a top view of the manure plate 1. When the high-speed airflow has not yet reached the position of the manure plate 1, its direction is perpendicular to the direction of the manure plate 1. When the high-speed airflow enters the air guide duct formed by the two adjacent arc-shaped plates 22, under the guidance of the air guide duct, the direction of the high-speed airflow is changed and it is directed along... Figure 5 Move in the direction indicated by the arrow in the upper middle side view. Figure 5 The lower middle side view shows the movement path of the high-speed airflow without the arc plate 22. It can be clearly seen from the figure that after the arc plate 22 is installed, the high-speed airflow is guided by the air duct composed of several arc plates 22, which increases the distance the high-speed airflow moves when passing through the manure plate 1 (it can be seen from the figure that S1 is significantly greater than S2). That is, it is equivalent to increasing the residence time of the airflow on the manure surface when passing through the manure on the manure plate 1, thereby increasing the contact time between the airflow blown out from the drying equipment and the manure, and thus improving the drying efficiency.

[0026] In addition, since the manure board 1 is provided with high-density ventilation holes 21, it can both support the manure and allow the high-speed airflow to come into contact with the manure in the lower layer when passing through the manure board 1 (the manure in the surface area of ​​the manure board 1 has the largest contact area with the airflow and the best drying effect, while the manure in the lower layer that is covered cannot come into contact with the airflow and therefore has a poor drying effect). In this solution, the high-density ventilation holes 21 provided on the manure board 1 can effectively improve the above situation (allowing the manure in the lower layer to also come into contact with the airflow and achieve a certain drying effect).

[0027] In this solution, the manure plate 1 and the nylon plug 12 are detachable. When the manure plate 1 has been used for a period of time and needs to be cleaned, the manure plate 1 can be removed from the nylon plug 12 and the nylon plug 12 and the manure plate 1 can be cleaned separately. If the whole thing is cleaned directly, on the one hand, the large size makes cleaning inconvenient, and on the other hand, since the nylon plug 12 and the manure plate 1 are connected together, it is difficult to clean the corner where the two fit together, resulting in inconvenience and poor cleaning effect. This solution can better avoid the above situations.

[0028] As attached Figure 6 As shown in the attached diagram, when the manure board 1 moves to point A (or to point B) and changes from a horizontal to a vertical position, [the following is an example]. Figure 8 The diagram shows the state of manure plate 1 at point A (B). Since manure plate 1 is in a vertical state at this time, when the high-speed airflow passes through the air guide formed by the two adjacent arc-shaped plates 22, its movement direction is adjusted and it moves along... Figure 8 The middle arrow points to the movement (the airflow moves from top to bottom and is blown across the surface of the manure board 1). The high-speed airflow acts on the feces attached to the surface of the manure board 1 and exerts a certain force on it. This force has a component in the same direction as the gravity of the fecal residue, which improves the cleaning effect of the high-speed airflow on the fecal residue attached to the surface of the manure board 1). At this time, the high-speed airflow can blow away the fecal residue attached to the surface of the manure board 1 and let it fall onto the lower manure board 1 (to prevent too much fecal residue from being attached to the manure board 1, which would block the high-density ventilation holes 21 and affect the drying effect on the feces below the surface).

[0029] Example 2, based on Example 1, as shown in the appendix Figure 1 As shown, reinforcing ribs 11 are integrally provided on both sides of the manure board 1 in the transverse direction, making the cross-section of the manure board 1 have an inverted trapezoidal shape, as shown in the attached figure. Figure 4 As shown, the cross-section of the nylon plug 12 is also inverted trapezoidal. With the cooperation of the manure plate 1, the reinforcing bending rib plate 11 and the nylon plug 12, the manure plate 1 is just locked onto the nylon plug 12, which further increases the connection stability between the two. At the same time, the setting of the reinforcing bending rib plate 11 also further increases the structural strength of the manure plate 1 (improving its durability).

[0030] Example 3, based on Example 1, as shown in the appendix. Figure 2 , 4 As shown in the figure, the nylon plug 12 is provided with a guide post hole 19 that mates with the axial direction, and one end of the shaft pin 14 is provided with a hexagonal cap 5. The inner side of the nylon plug 12 is provided with a hexagonal groove 6 that mates with the hexagonal cap 5. The operator passes the shaft pin 14 axially from the inner side of the nylon plug 12 through the guide post hole 19 to the outside so that the hexagonal cap 5 is placed in the hexagonal groove 6 as shown in the figure. This achieves the circumferential positioning of the shaft pin 14.

[0031] As attached Figure 7 As shown, a movable gear 3 is rotatably mounted on one end of the outward-extending pin 14, and a fixed gear (not shown in the figure) that meshes with the movable gear 3 is fixedly mounted on the inner wall of the drive chain 2. The movable gear 3 drives a vibration mechanism installed below the manure plate 1. In specific use, the process is as follows:

[0032] As attached Figure 6 As shown, when the manure plate 1 moves to point A along the drive chain 2, the guide wheel 13 on the manure plate 1 no longer contacts the guide rail 23, and the manure plate 1 begins to rotate relative to the drive chain 2 via the shaft pin 14 (thus tilting the accumulated manure onto the lower manure plate 1). During the rotation of the manure plate 1 relative to the drive chain 2 via the shaft pin 14, the movable gear 3 is driven to rotate relative to the shaft pin 14 through the cooperation of the movable gear 3 and the fixed gear. As the movable gear 3 rotates, it synchronously drives the vibration mechanism located below the manure plate 1 to work. That is, the vibration mechanism applies a certain degree of vibration force to the manure plate 1 so that the manure residue attached to the surface of the manure plate 1 can be better separated from the surface of the manure plate 1 under the action of vibration, so as to avoid excessive manure residue adhering to the surface of the manure plate 1 and causing the high-density ventilation holes 21 to be blocked, thus affecting the drying effect.

[0033] Note: A movable gear 3 is rotatably mounted on the shaft pin 14 on only one longitudinal side of the manure plate 1 (a fixed gear is mounted on the inner wall of the drive chain 2 located in the longitudinal first position). This allows the manure plate 1 to rotate relative to the drive chain 2 when it moves to point A, and the vibration mechanism is driven to strike and vibrate the manure plate 1 through the cooperation of the fixed gear and the movable gear 3.

[0034] Example 4, based on Example 3, as shown in the appendix. Figure 2As shown, a thrust cap pan head bolt 15 is threadedly installed inside the nylon plug 12 and near the hexagonal groove 6. When the hexagonal cap on the shaft pin 14 is placed in the hexagonal groove 6, the shaft pin 14 can be positioned axially by installing the thrust cap pan head bolt 15 inside the nylon plug 12 and pressing its large cap plate against the hexagonal cap 5 (to prevent it from coming out of the guide post hole 19).

[0035] Example 5, based on Example 1, as shown in the appendix. Figure 4 As shown, a positioning bolt hole 20 is provided at the end of the nylon plug 12 away from the guide post hole 19, and an external hexagonal semi-threaded screw 17 (with threads on its surface) is fitted on the guide wheel 13. The external hexagonal semi-threaded screw 17 passes through the positioning bolt hole 20 and is fitted with a thrust locking nut 18 at one end of the nylon plug 12. The thread length on the external hexagonal semi-threaded screw 17 is just enough to meet the fit with the positioning bolt hole 20 and the thrust locking nut 18. The guide wheel 13 is fitted in the area where the external hexagonal semi-threaded screw 17 is not threaded (so as to realize the rotation of the guide wheel 13 relative to the external hexagonal semi-threaded screw 17).

[0036] Example 6, based on Example 3, as shown in the appendix Figure 9 As shown, the vibration mechanism includes a striking shaft 7 rotatably mounted between two nylon plugs 12 (a torsion spring is provided between the striking shaft 7 and the nylon plugs 12, which is not shown in the figure), and striking rods 8 (multiple of which are spaced apart along the length of the striking shaft 7) are fixed radially on the striking shaft 7. A striking ball 9 is provided at one end of the striking rod 8. A camshaft 10 that cooperates with the striking rod 8 is rotatably mounted between the two nylon plugs 12 that cooperate with the manure plate 1, and the camshaft 10 is driven by a movable gear 3. The torsion spring ensures that the striking shaft 7 remains stationary when it is not subjected to external force. Figure 9 As shown in the upper-middle side view, the striking ball 9 is positioned against the lower surface of the manure plate 1. When the manure plate 1 moves to point A and, under the action of the movable gear 3 and the fixed gear, drives the movable gear 3 to rotate, it synchronously drives the two striking shafts 7 to rotate relative to the nylon plug 12, thereby synchronously driving the two camshafts 10 to rotate. When the camshafts 10 move from the attached... Figure 9 As shown in the upper-middle side view, when the camshaft 10 begins to rotate from its position away from its axis of rotation and disengages from the striking rod 8, the striking shaft 7, under the action of the torsion spring, begins to drive the striking ball 9 to rotate rapidly in the opposite direction (i.e., as shown in the attached figure). Figure 9 (As shown by the arrow in the lower middle side view), the striking ball 9 stops rotating after hitting the surface of the manure board 1, and the above impact process generates a certain degree of vibration, which can realize the separation of fecal residue attached to the surface of the manure board 1 from the manure board 1 under the action of vibration.

[0037] This embodiment provides a specific structure for a movable gear 3 to drive two striking shafts 7, as follows:

[0038] As attached Figure 7 As shown, pulleys are provided at the end of the striking shaft 7 extending outward from the nylon plug 12, and pulleys are also provided at the end of the shaft pin 14 extending outward from the nylon plug 12 (the pulleys rotate coaxially with the movable gear 3, that is, a connecting piece can be provided between the pulleys and the movable gear 3 so that when the movable gear 3 rotates, it can synchronously drive the pulleys to rotate). The three pulleys are connected by belts (the belts are not labeled in the figure). When the manure plate 1 rotates relative to the drive chain 2, it drives the movable gear 3 to rotate, and through the transmission between the pulleys and the belt, it can drive the two striking shafts 7 to rotate synchronously, and then through the cooperation of the camshaft 10, the striking rod 8, and the striking ball 9, it can strike the manure plate 1 (generating vibration).

[0039] Example 7, based on Example 1, as shown in the appendix Figure 1 As shown, the manure plate 1 is fixedly installed on the nylon plug 12 on both longitudinal sides by countersunk bolts 16, which can realize the disassembly and installation of the manure plate 1 and the nylon plug 12.
