Description

Technical Field

[0001] The present invention relates to the field of crushing technology, in particular to a circulating crusher for dry-mixed mortar. Background Art

[0002] Dry-mix mortar is a premixed material composed of cement, sand, mineral admixtures, and additives in a specific proportion. It offers advantages such as stable quality, convenient construction, and environmental friendliness. It is widely used in building wall construction, plastering, and floor paving. With the advancement of building industrialization and green building policies, the market demand for dry-mix mortar continues to grow, placing higher demands on production efficiency and material handling capabilities.

[0003] For example, in a sand and gravel crushing and screening device described in patent number CN117019356A, when the device is used, after the filter plate has screened the sand and gravel for a period of time, large pieces of sand and gravel remain on the filter plate. It is necessary to first stop the rotation of the crushing roller and stop feeding sand and gravel into the box. The large pieces of sand and gravel must be cleaned before the crushing work can continue. This makes the device unable to perform continuous crushing operations during operation, which undoubtedly reduces the crushing efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a circulating crusher for dry-mixed mortar.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A circulating crusher for dry-mixed mortar, including a base, a material drop box, a first crushing box, a feed box, a second crushing box, an outer baffle, and a material drop chute. The base is provided with a slow-down component, the slow-down component is used for intermittently dropping the primary crushed mortar, the base is further provided with a discharge component, the discharge component is used for further dropping the primary crushed mortar, and the base is provided with a knocking component, the knocking component is used to knock the lower surface of the material drop chute;

[0007] The slow-descent assembly consists of a driving part, a sliding part, and a rotating part. The driving part is provided with a first incomplete gear, the sliding part is provided with a first rack, and the rotating part is provided with a fourth rotating shaft and a blanking plate. The driving part drives the first incomplete gear to rotate counterclockwise to make the sliding part slide back and forth. When the sliding part slides back and forth, the toothed part of the first rack engages with the rotating part for transmission, driving the rotating part to rotate back and forth around the fourth rotating shaft, thereby driving the blanking plate to rotate back and forth.

[0008] Preferably, the discharge assembly consists of a rebound part and a discharge part, and the knocking assembly consists of another group of rebound parts and a knocking part, and the two groups of rebound parts are meshed and driven by a second incomplete gear.

[0009] Preferably, the rotating part is arranged in a material drop box, and a crushing assembly is provided in the first crushing box. The crushing assembly crushes the material preliminarily and then drops the material onto the rotating part in the material drop box, and is discharged downward through buffering by the rotating part. The second crushing box is provided with a crushing mechanism, which is used for further crushing the preliminarily crushed material.

[0010] Preferably, the knocking part is fixedly connected above another set of rebound parts. When the second incomplete gear rotates counterclockwise, the rebound part is compressed downward. When the second incomplete gear rotates to the toothless part, the rebound part resets and moves upward, thereby driving the knocking part to move upward and knock the lower surface of the blanking trough.

[0011] Preferably, the discharge part and the rebound part are fixedly connected by a connecting plate. When the second incomplete gear rotates counterclockwise, the rebound part is stretched upward. When the second incomplete gear rotates to the toothless part, the rebound part resets and moves downward, thereby driving the discharge part to slide back and forth.

[0012] Preferably, a transmission mechanism and two sets of synchronous parts are provided on the base, the transmission mechanism drives one set of synchronous parts to rotate, one set of synchronous parts is engaged with the other set of synchronous parts through a first gear, and the crushing assembly and the crushing mechanism move synchronously through the other set of synchronous parts.

[0013] Preferably, a first mounting plate and a fifth mounting plate are provided below the material drop chute, the driving part is provided on the first mounting plate and the fifth mounting plate, and a fixing column is provided on the first crushing box.

[0014] The present invention has the following beneficial effects:

[0015] 1. In the present invention, when the dry-mixed mortar needs to be crushed, it is put into the feed box, and the dry-mixed mortar that has been preliminarily crushed by the crushing assembly falls above the rotating part in the discharge box. The driving part drives the first incomplete gear to rotate counterclockwise, so that the sliding part as a whole slides back and forth. When the sliding part slides back and forth, the rotating part is driven to rotate back and forth around the fourth rotating axis, and then the dry-mixed mortar accumulated above the rotating part continues to be discharged downward, thereby buffering its falling speed.

[0016] 2. Furthermore, when the second incomplete gear rotates counterclockwise, the rebound part is compressed downward. When the second incomplete gear rotates to the toothless part, the rebound part resets and moves upward, thereby driving the knocking part to move upward and knock the lower surface of the blanking plate, which can vibrate and disperse the dry-mixed mortar that falls above the blanking plate, making it easier for it to be discharged downward on the slope of the blanking plate.

[0017] 3. Furthermore, when the second incomplete gear rotates counterclockwise, the rebound part is stretched upward. When the second incomplete gear rotates to the toothless part, the rebound part is reset and moved downward, thereby driving the discharge part to slide back and forth. When the discharge part slides upward, the dry-mixed mortar discharged by the blanking plate can be blocked. When it slides downward, the dry-mixed mortar discharged by the blanking plate can be discharged into the second crushing box for further crushing. The intermittent discharge of the discharge part can prevent excessive material from being discharged into the second crushing box, causing it to be blocked. BRIEF DESCRIPTION OF THE DRAWINGS

The second guide rod 48 is installed between each group of second mounting plates 32. The slide 31 slides on the second guide rod 48, and the outer baffle 6 is fixedly connected to the side of the blanking box 2 close to the sliding part.

[0038] The rotating part consists of a fourth rotating shaft 29, a blanking plate 30, and a third gear 28. The fourth rotating shaft 29 is rotatably connected to the blanking box 2. The blanking plate 30 is fixedly connected to the fourth rotating shaft 29. One end of the fourth rotating shaft 29 close to the first rack 27 is fixedly connected to the third gear 28. The third gear 28 is engaged with the corresponding toothed part on the first rack 27.

[0039] In this embodiment, the crushing assembly and crushing mechanism may specifically adopt the following structure:

[0040] The crushing assembly consists of a first crushing roller 19 and a first rotating shaft 17. The first rotating shaft 17 is rotatably connected to the side wall of the first crushing box 3. The first crushing roller 19 is fixedly connected to the first rotating shaft 17. The two first gears 15 are fixedly connected to the first rotating shaft 17 and mesh with each other. The fixed column 7 is fixedly connected to the side close to the second mounting plate 32. The other end of the first rotating shaft 17 is rotatably connected to the fixed column 7.

[0041] The crushing mechanism consists of a second rotating shaft 18, a second crushing roller 20, and a second gear 16. The second rotating shaft 18 is rotatably connected to the second crushing box 5. The second crushing roller 20 is fixedly connected to the second rotating shaft 18. The blanking chute 46 is arranged at the lower end of the blanking box 2. The second crushing box 5 is arranged downstream of the slope of the blanking chute 46. The second gear 16 is fixedly connected to one end of the second rotating shaft 18 close to the first mounting plate 22, and the two second gears 16 are engaged with each other.

[0042] The transmission mechanism and the two sets of synchronization parts can specifically adopt the following structures:

[0043] The transmission mechanism is composed of a first motor 8, wherein one set of synchronization parts is composed of a first rotating wheel 9, a first synchronous belt 10, and a second rotating wheel 11, and the other set of synchronization parts is composed of a third rotating wheel 12, a second synchronous belt 13, and a fourth rotating wheel 14. Figure 3 The output shaft of the first motor 8 is fixedly connected to the first rotating wheel 9, the second rotating wheel 11 is fixedly connected to the first rotating shaft 17 on the right side, the first rotating wheel 9 and the second rotating wheel 11 are connected by a first synchronous belt 10, the third rotating wheel 12 is fixedly connected to the first rotating shaft 17 on the left side, the fourth rotating wheel 14 is fixedly connected to one end of one of the second rotating shafts 18, and the third rotating wheel 12 and the fourth rotating wheel 14 are connected by a second synchronous belt 13.

[0044] In this embodiment, when the dry-mixed mortar needs to be crushed, it is put into the feed box 4, and the first motor 8 and the second motor 21 are started. The first motor 8 drives the two first crushing rollers 19 to rotate through a set of synchronization parts. After the material is initially crushed by the two first crushing rollers 19, it falls downward into the blanking box 2 and is blocked by the blanking plate 30 for buffering. When the second motor 21 is started, it drives the third rotating shaft 23 and the first incomplete gear 24 to rotate, thereby driving the annular gear plate 25 to slide back and forth, and then drives the first connecting rod 26 and the first rack 27 to slide back and forth, driving the third gear 28, the fourth rotating shaft 29, and the blanking plate 30 to rotate back and forth, so that most of the material fallen on the blanking plate 30 can continue to be discharged downward.

[0045] It should be noted that when the annular tooth plate 25 slides back and forth, it can drive the telescopic sleeve 34 to slide back and forth. The telescopic sleeve 34 can make the movement of the annular tooth plate 25 more stable. In the initial state, there is a gap between the two opposite blanking plates 30. A small part of the initially crushed material is discharged downward through the gap, and most of the material will be blocked and buffered by the blanking plates 30 and then continue to be discharged downward. The toothed part of the first rack 27 is not engaged with the third gear 28 in the initial state. When the first rack 27 gradually slides upward, it engages with it, driving the blanking plate 30 to rotate to increase the gap, thereby discharging more material downward.

[0046] Example 2:

[0047] Reference Figure 4 、 Figure 6 The discharge component is composed of a rebound part and a discharge part, and the knocking component is composed of another group of rebound parts and a knocking part. The two groups of rebound parts are engaged and driven by a second incomplete gear 35.

[0048] The striking part is fixedly connected above another set of rebound parts. When the second incomplete gear 35 rotates counterclockwise, the rebound part is compressed downward. When the second incomplete gear 35 rotates to the toothless part, the rebound part resets and moves upward, thereby driving the striking part to move upward and strike the lower surface of the blanking trough 46.

[0049] In this embodiment, in combination with the first embodiment, the striking assembly is composed of a set of a rebound portion and a striking portion. The rebound portion and the striking portion may specifically adopt the following structures:

[0050] The rebound part is composed of a second rack 36, a first guide rod 45, a slide rod 39, a slider 42, a fourth mounting plate 41, and a spring 40. The upper ends of the first guide rod 45 and the slide rod 39 are fixedly connected to the lower end of the blanking trough 46, the lower end of the first guide rod 45 is fixedly connected to the base 1, the lower end of the slide rod 39 is fixedly connected to the fourth mounting plate 41, the second rack 36 slides on the first guide rod 45, the slider 42 is fixedly connected to the side wall of the second rack 36 and slides on the slide rod 39, the spring 40 is fixedly connected between the slider 42 and the fourth mounting plate 41, and the second incomplete gear 35 is fixedly connected to the third rotating shaft 23.

[0051] The knocking part is composed of a second connecting rod 38 and a knocking block 37 . The second connecting rod 38 is fixedly connected to the knocking block 37 . One end of the second connecting rod 38 away from the knocking block 37 is fixedly connected to the upper end of the second rack 36 .

[0052] This embodiment is combined with embodiment one. In embodiment one, the material dropped through the slow-down assembly falls onto the chute 46 and slides downward on the slope of the chute 46. In this embodiment, when the second motor 21 drives the third rotating shaft 23 to rotate, the second incomplete gear 35 engages with the second rack 36, driving the second rack 36 and the slider 42 to slide downward and compress the spring 40. When the second incomplete gear 35 rotates to the toothless part, the rebound part resets and moves upward, driving the knocking block 37 thereon to knock on the lower surface of the chute 46, so that the dry-mixed mortar that falls above the chute 46 can be vibrated and dispersed, making it easier for it to be discharged downward on the slope of the chute 46.

[0053] Example 3:

[0054] Reference Figure 4 、 Figure 6 The discharge part and the rebound part are fixedly connected by a connecting plate 43. When the second incomplete gear 35 rotates counterclockwise, the rebound part is stretched upward. When the second incomplete gear 35 rotates to the toothless part, the rebound part is reset and moved downward, thereby driving the discharge part to slide back and forth.

[0055] In this embodiment, the discharge assembly is composed of another set of rebound parts and discharge parts. Figure 6 , the rebound part and the discharge part can adopt the following structure:

[0056] The rebound part is composed of a second rack 36, a first guide rod 45, a slide rod 39, a connecting plate 43, a fourth mounting plate 41, and a spring 40. The upper ends of the first guide rod 45 and the slide rod 39 are fixedly connected to the lower end of the blanking trough 46, the lower end of the first guide rod 45 is fixedly connected to the base 1, the lower end of the slide rod 39 is fixedly connected to the fourth mounting plate 41, the second rack 36 slides on the first guide rod 45, the connecting plate 43 is fixedly connected to the side wall of the second rack 36 and slides on the slide rod 39, and the spring 40 is fixedly connected between the slider 42 and the fourth mounting plate 41.

[0057] The discharge portion is composed of a baffle 44 , the lower end of which is fixedly connected to the connecting plate 43 and slides on the right side of the blanking chute 46 .

[0058] This embodiment is combined with the first and second embodiments, and the material sliding down from the slope of the chute 46 enters the second crushing box 5 for secondary crushing. When the second motor 21 drives the third rotating shaft 23 to rotate, in the other set of rebound parts, the second incomplete gear 35 is engaged with its corresponding second rack 36, driving the second rack 36, the connecting plate 43, and the baffle 44 to slide upward and compress the spring 40. When the second incomplete gear 35 rotates to the toothless part, the rebound part resets and moves upward, and the baffle 44 resets. When the baffle 44 moves upward, it can block the material at the lower end of the chute 46. When the baffle 44 moves downward, it can release the material into the second crushing box 5 for crushing.

[0059] It should be noted that the coordinated arrangement of the discharge part and the slow-down assembly can buffer the material flow pressure in the device when more materials need to be crushed, thereby avoiding the accumulation of a large amount of materials in the second crushing box 5 and causing blockage, thereby improving the crushing efficiency.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
