DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following combination Figures 1-3 The utility model describes a drum composting reactor with a feed door that can automatically seal.

[0030] The embodiment of the utility model discloses a drum composting reactor capable of automatically sealing a feed door, comprising a drum 1, a feed door 2, a door opening component 3, a reset component 4 and a rolling component 5.

[0031] The axis of the drum 1 extends along a first direction. The drum 1 has a first end plate 11 and a second end plate 12 that are arranged opposite to each other in the first direction. The first end plate 11 is provided with a feed port.

[0032] The feed gate 2 is provided at the feed inlet and is located inside the drum 1. The feed gate 2 can rotate relative to the drum 1 to open or close the feed inlet.

[0033] The door opening assembly 3 is arranged outside the drum 1 and is connected to the feed door 2 by abutment. The door opening assembly 3 can push the feed door 2 into the drum 1 to open the feed port.

[0034] The reset assembly 4 is arranged in the drum 1 and connected to the feed door 2. The reset assembly 4 can push the feed door 2 out of the drum 1 to close the feed port.

[0035] The drum 1 is connected to a rolling assembly 5 , and the rolling assembly 5 is used to drive the drum 1 to rotate in a first direction.

[0036] For example, in order to make the technical solution of the present application easier to understand, the following further describes the technical solution of the present application by taking the first direction and the left-right direction as an example, wherein the left-right direction is as follows: Figure 1 shown.

[0037] The axis of the drum 1 extends left and right, and a first end plate 11 and a second end plate 12 are respectively provided at both ends of the drum 1 , wherein a feed port is provided on the first end plate 11 for materials to enter the drum 1 .

[0038] The feed gate 2 is arranged inside the drum 1. In the radial direction of the drum 1, the feed gate 2 has an inner end adjacent to the axis of the drum 1 and an outer end away from the axis of the drum 1. The outer end of the feed gate 2 is hingedly connected to the first end plate 11 so that the feed gate 2 can rotate relative to the first end plate 11, thereby realizing the opening and closing operation of the feed port.

[0039] When the feeding is needed, the door opening assembly 3 pushes the feeding door 2 towards the inside of the drum 1 to open the feeding port, and after the feeding is completed, the door closing assembly pushes the feeding door 2 to the outside of the drum 1 to close the feeding port.

[0040] The rolling assembly 5 can drive the drum 1 to rotate, so as to fully mix the materials in the drum 1 and accelerate the fermentation efficiency. For example, a first gear 14 is arranged on the outside of the drum 1, the rolling assembly 5 comprises a second gear 51 and a motor 52. A base 6 is arranged at the bottom of the drum 1, the second gear 51 is arranged on the base 6, and the first gear 14 and the second gear 51 are engaged. The motor 52 is used to drive the first gear 14 to rotate, thereby driving the second gear 51 to rotate, and further driving the drum 1 to rotate.

[0041] When the drum compost reactor capable of automatically sealing the feeding door is used, first, the operator starts the door opening assembly 3, the door opening assembly 3 pushes the feeding door 2, and the feeding door 2 is rotated towards the inside of the drum 1, so as to open the feeding port. At this time, the materials can enter the inside of the drum 1 through the feeding port, and the feeding process is completed. When the feeding is completed, the operator stops the pushing action of the door opening assembly 3, and the door opening assembly 3 gradually returns to the initial position. At the same time, the resetting assembly 4 pushes the feeding door 2 to the outside of the drum 1, so that the feeding door 2 is automatically reset and the feeding port is closed. The process is fully automated, and manual opening or resetting of the feeding door 2 is not needed, so that the frequency and intensity of manual operation are greatly reduced, and the work efficiency is significantly improved.

[0042] Therefore, the drum compost reactor capable of automatically sealing the feeding door has the advantages of high automation degree.

[0043] In some embodiments, the door opening assembly 3 comprises a driving member 31 and a driving rod 32, one end of the driving rod 32 is connected with the driving member 31, the other end of the driving rod 32 is connected with the feeding door 2 in abutment, and the driving member 31 can drive the driving rod 32 to move in the first direction.

[0044] For example, the driving rod 32 is not directly connected with the feeding door 2, but is connected with the feeding door 2 in abutment, that is, the driving rod 32 can push the feeding door 2 or move away from the feeding door 2. The driving rod 32 moves in the left-right direction,

[0045] When the feeding port needs to be opened, the operator starts the driving member 31, the driving member 31 drives the driving rod 32 to move to the left in the left-right direction, and the left end of the driving rod 32 pushes the feeding door 2, so that the feeding door 2 opens the feeding port.

[0046] When the feeding is completed, the driving member 31 reverses the action, the driving rod 32 moves to the right in the left-right direction, and the feeding door 2 automatically closes the feeding port under the action of the resetting assembly 4.

[0047] Therefore, the drum compost reactor capable of automatically sealing the feeding door simplifies the operation process, reduces manual intervention, and improves the reliability and working efficiency of the drum compost reactor capable of automatically sealing the feeding door. In addition, by accurately controlling the stroke and force of the driving member 31, it can be ensured that the feeding door 2 can be accurately positioned in each operation, further improving the stability and safety of the drum compost reactor capable of automatically sealing the feeding door.

[0048] The driving member 31 is fixed on the first end plate 11, and the driving member 31 is arranged on one side of the feeding door 2, so as to avoid affecting the feeding process.

[0049] It should be noted that the feeding door 2 has an inner end adjacent to the axis of the drum 1 and an outer end away from the axis of the drum 1, and the outer end of the feeding door 2 is hingedly connected to the first end plate 11. The part of the driving rod 32 pushing the feeding door 2 is in the middle region between the inner end and the outer end of the feeding door 2, and if the outer end of the feeding door 2 is pushed, the driving force required is too large, and if the outer end of the feeding door 2 is pushed, the driving rod 32 is easy to be empty when the feeding door 2 rotates, so that the feeding door 2 cannot be opened.

[0050] Optionally, the left end of the driving rod 32 is provided with a rubber head, which can effectively reduce the wear of the driving rod 32 and the feeding door 2 when they are in contact, and prolong the service life of the feeding door 2 and the driving rod 32. The softness of the rubber material can provide buffering when in contact, avoiding hard collision between the two.

[0051] Optionally, the door opening assembly 3 is an electric push rod.

[0052] In some embodiments, the drum 1 comprises a cylinder wall 13 arranged between the first end plate 11 and the second end plate 12.

[0053] The reset assembly 4 comprises a spring push rod 41 and a base 40, the base 40 is fixedly connected with the cylinder wall 13, the base 40 is arranged in the first direction and spaced apart from the first end plate 11, one end of the spring push rod 41 is rotatably connected with the base 40, and the other end of the spring push rod 41 is rotatably connected with the feeding door 2, and the spring push rod 41 has an acting force for closing the feeding port of the feeding door 2.

[0054] For example, as shown in Figure 2 The base 40 is fixedly connected with the cylinder wall 13, for example, the base 40 is welded on the cylinder wall 13. The base 40 is arranged in the first direction and spaced apart from the first end plate 11, one end of the spring push rod 41 is hingedly connected with the base 40, and the other end of the spring push rod 41 is hingedly connected with the feeding door 2.

[0055] The spring push rod 41 is internally provided with a pre-tightening force adjustable spring 44, which can provide an action force to promote the feeding door 2 to close the feeding port after the feeding door 2 is opened. Specifically, when the rolling assembly 5 pushes the feeding door 2 to open the feeding port, the spring push rod 41 will be stretched or compressed, storing a certain potential energy. When the rolling assembly 5 retreats, the spring push rod 41 restores to its original state under the action of the internal spring 44, pushing the feeding door 2 to move towards the inside of the drum 1, so as to automatically close the feeding port of the feeding door 2.

[0056] In some embodiments, the spring push rod 41 comprises a sliding rod 42 and a sliding block 43, one end of the sliding rod 42 is rotatably connected with the base 40, the sliding block 43 is sleeved on the other end of the sliding rod 42 and can move along the sliding rod 42, and the sliding block 43 is rotatably connected with the feeding door 2.

[0057] For example, as shown in Figure 2 and Figure 3 , one end of the sliding rod 42 is hingedly connected with the base 40, and the sliding block 43 is hingedly connected with the feeding door 2. The sliding block 43 can slide on the sliding rod 42, ensuring that the spring push rod 41 can adapt to different positions and angle changes of the feeding door 2 during the opening and closing process of the feeding door 2, and providing a smooth motion trajectory. This flexibility makes the opening and closing of the feeding door 2 more smooth, reducing the jamming and resistance.

[0058] In some embodiments, the spring push rod 41 comprises a spring 44, the spring 44 is sleeved on the sliding rod 42, one end of the sliding rod 42 is provided with a first stop portion 45, the sliding block 43 is provided with a second stop portion 46, one end of the spring 44 is connected with the first stop portion 45, the other end of the spring 44 is connected with the second stop portion 46, and the spring 44 has an action force to promote the sliding block 43 to move away from the first stop portion 45.

[0059] For example, as shown in Figure 3 , the design of the first stop portion 45 and the second stop portion 46 ensures that the spring 44 will not come out or deviate during work, maintaining the stability and reliability of the spring 44. This makes the opening and closing process of the feeding door 2 more stable, reducing unnecessary vibration and impact.

[0060] Optionally, the first stop portion 45 and the second stop portion 46 are both annular protrusions. The first stop portion 45 is outwardly protrudingly arranged from the surface of the sliding rod 42, and the second stop portion 46 is outwardly protrudingly arranged from the surface of the sliding block 43. The spring 44 is welded or clamped to the first stop portion 45, and the spring 44 is welded or clamped to the second stop portion 46.

[0061] In some embodiments, the spring push rod 41 comprises a first stopper 47, one end of the slide rod 42 is provided with a threaded segment 421, the first stopper 47 is sleeved on the threaded segment 421 and is threadedly connected with the threaded segment 421, and the first stopper 47 is provided with an annular protrusion to form a first stopper part 45.

[0062] For example, as shown in Figure 3 the threaded segment 421 is provided on one end of the slide rod 42 adjacent to the drum wall 13. The first stopper 47 is threadedly connected with the threaded segment 421. On the one hand, the threaded connection provides a firm and reliable connection mode, ensuring that the first stopper 47 will not loosen or fall off during work. The design of the annular protrusion further enhances the stability of the first stopper part 45, ensuring that the spring 44 can maintain the correct posture during compression and stretching, avoiding deviation or falling out. On the other hand, the first stopper 47 can be fine-tuned on the threaded segment 421 of the slide rod 42, thereby accurately adjusting the pre-tightening force of the spring 44, and further ensuring that the feed door 2 can be smoothly closed under various conditions, prolonging the service life of the drum composting reactor capable of automatically sealing the feed door.

[0063] In some embodiments, the spring push rod 41 is provided in plurality, and the plurality of spring push rods 41 are arranged at intervals.

[0064] For example, a plurality of bases 40 are fixed on the drum wall 13 of the drum 1, and one spring push rod 41 is connected to each base 40. The plurality of bases 40 are arranged on the same base plate.

[0065] The plurality of spring push rods 41 can better ensure that the feed door 2 closely fits the wall of the drum 1 when closed, providing better sealing effect. Moreover, the design of multi-point support can disperse the pressure borne by the feed door 2 when closed, reducing the load of a single spring push rod 41, thereby prolonging the service life of the entire drum composting reactor capable of automatically sealing the feed door.

[0066] Optionally, the spring push rod 41 is provided in two, three or four.

[0067] In some embodiments, the sliding block 43 is hingedly connected with the feed door 2 through a ball hinge 7.

[0068] For example, as shown in Figure 2 the connection between the sliding block 43 and the feed door 2 adopts a ball hinge 7 structure. This design allows the feed door 2 to freely rotate in multiple directions, ensuring smooth movement of the feed door 2.

[0069] In addition, the ball hinge 7 connection can also absorb certain impact and vibration, prolonging the service life of the feed door 2 and the sliding block 43, and improving the overall reliability of the drum composting reactor capable of automatically sealing the feed door.

[0070] In some embodiments, the barrel wall 13 is provided with an access hole and an access plate 131, the access hole is arranged adjacent to the reset assembly 4, and the access plate 131 is detachably arranged at the access hole.

[0071] For example, as shown in Figure 1 The position of the access hole is designed very close to the reset assembly 4, so that the technician can conveniently maintain the reset assembly 4.

[0072] The operator can maintain and repair the reset assembly 4 through the access hole, or adjust the position of the first stopper 47 on the threaded section 421 through the access hole, so as to adjust the pre-tightening force of the spring 44, and ensure that it is always in the best working condition, thereby prolonging the service life of the equipment and maintaining the high efficiency of the operation.

[0073] The access hole is usually equipped with a cover plate that is easy to open and close, ensuring that it is sealed in the non-maintenance state, preventing material leakage and foreign matter from entering the inside of the drum 1. This design not only improves the maintainability of the system, but also simplifies the process of daily maintenance and troubleshooting.

[0074] In some embodiments, the area of the feed door 2 is larger than the area of the feed port, and the feed door 2 is provided with a sealing gasket (not shown in the figure). Thus, the drum compost reactor capable of automatically sealing the feed door according to the embodiments of the present application can not only completely cover the feed port to prevent material from leaking from the gap during the rotation of the drum 1, but also effectively prevent the escape of odors, thereby maintaining the cleanliness and hygiene of the working environment.

[0075] The sealing gasket can tightly fit the edge of the feed port when the feed door 2 is closed, forming an effective sealing barrier. In this way, even in the case of long-term operation and frequent opening and closing of the drum 1, good sealing performance can be maintained, and the service life of the equipment can be prolonged.

[0076] In addition, the area of the feed door 2 is larger than the area of the feed port, so even if there is an alignment error, the feed port can still be effectively closed, further improving the stability and reliability of the drum compost reactor capable of automatically sealing the feed door.

[0077] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
