Technical Field

[0001] This utility model relates to the field of rosemary preparation technology, and in particular to a rosemary pulverizing device. Background Technology

[0002] Rosemary is an evergreen aromatic shrub native to the Mediterranean region. Its leaves are commonly used for cooking and seasoning, traditional medicine, and essential oil extraction. Extracting essential oil from rosemary requires pre-grinding; however, existing rosemary grinding devices typically use a single-pass grinding method, which easily leads to uneven grinding. Furthermore, excessively large pieces can clog the filter mesh, preventing the ground material from flowing out properly. Utility Model Content

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figure 1-4As shown, a rosemary crushing device includes a feed pipe 1, a crushing section 2, a shell 3, a crushing section 4, a screen 5, a scraper section 6, and a discharge pipe 7; the upper end of the shell 3 is connected to the feed pipe 1, and the lower end is connected to the discharge pipe 7; the crushing section 2 is provided inside the feed pipe 1; the crushing section 4 is provided inside the shell 3; the screen 5 is detachably connected inside the shell 3 below the crushing section 4; the scraper section 6 is located inside the shell 3 and its upper end is rotatably connected to the shell 3, and its lower end is in contact with the upper surface of the screen 5.

[0024] It should be noted that the feed pipe 1 is used for the intake of dried rosemary; the crushing section 2 is used for the initial crushing of rosemary; the shell 3 is the main crushing space; the crushing section 4 can effectively crush the rosemary; the screen 5 is used to screen out rosemary fragments that meet the particle size requirements; the scraper section 6 can clean the material blocked in the screen holes; and the discharge pipe 7 is used for the material to flow out.

[0025] Specifically, the crushing section 2 includes crushing rollers 21 and a first motor 22; two crushing rollers 21 are symmetrically arranged; the output end of the first motor 22 is fixedly connected to each of the two crushing rollers 21; both first motors 22 rotate towards the center of the feed pipe 1; and both first motors 22 are fixedly connected to the outside of the feed pipe 1. The outer circumferential surface of the crushing rollers 21 may be provided with raised tooth-like structures or textures to increase the gripping and initial crushing effect on the rosemary raw material. The remaining space between the crushing rollers 21 and the feed pipe 1 may be provided with limiting members 23 to facilitate the entry of rosemary from above the two crushing rollers 21, ensuring the initial compression of the material. The first motor 22 is preferably a geared motor with adjustable output speed to adapt to rosemary raw materials with different moisture contents or hardness.

[0026] Specifically, the crushing section 4 includes a crushing roller 41 and a second motor 42. The crushing roller 41 is rotatably connected inside the housing 3. The second motor 42 is fixedly connected to the outside of the housing 3, with its output end extending into the housing 3 and fixedly connected to the crushing roller 41. Several crushing blades 43 are movably connected to the periphery of the crushing roller 41. The crushing blades 43 can be detachably mounted on the crushing roller 41 by bolts or clips for easy replacement or maintenance. The blades 43 can be arranged in a spiral or staggered pattern to increase crushing efficiency and uniformity. The blades 43 are preferably made of stainless steel or tool steel, which have good wear resistance and corrosion resistance. The second motor 42 is preferably a high-speed motor, and its speed can be adjusted according to the required crushing particle size, for example, set to 2000–5000 rpm.

[0027] Specifically, the scraper section 6 includes a fixed ring 61, a first connecting rod 62, a scraper 63, a second connecting rod 64, a rotating ring 65, and a third motor 66. The third motor 66 is fixed to the outside of the housing 3, and its output end extends into the housing 3 and is fixed to the fixed ring 61, driving the fixed ring 61 to rotate. The fixed ring 61 is fixed to one end of the first connecting rod 62; the other end of the first connecting rod 62 is fixed to one end of the scraper 63; the other end of the scraper 63 is fixed to one end of the second connecting rod 64; the other end of the second connecting rod 64 is fixed to the rotating ring 65; the rotating ring 65 passes through the end of the crushing section 4 away from the third motor 66 and can rotate relative to the housing 3 and the crushing section 4. The scraper 63 has the same curvature as the screen 5 to ensure that the scraper 63 can fully contact the upper surface of the screen 5 and effectively scrape away the material blocking the screen holes. The bottom of the scraper 63 may be provided with an elastic material (such as rubber or polyurethane) to avoid damaging the screen 5 and improve the cleaning effect. The third motor 66 can be a stepper motor, which enables it to reciprocate on the screen 5 to clean the screen 5 and achieve a continuous and gentle scraping operation. It should be noted that the rotating ring 65 is only inserted through the end of the crushing part 4 away from the third motor 66 and does not have any contact with the crushing part 4. It is only rotatably connected to the housing 3. The rotation of the crushing part 4 and the scraper part 6 are relatively independent.

[0028] The sieve 5 is detachably installed inside the housing 3 via a slot or bolt, allowing for easy replacement of sieves with different apertures to meet the particle size requirements. For example, the aperture of the sieve 5 can be selected within the range of 0.5–2 mm to accommodate the particle size requirements of rosemary powder in different applications.

[0029] The discharge pipe 7 is located at the bottom of the shell 3 and is used to discharge rosemary powder that meets the particle size requirements. A valve or control mechanism can be installed at the discharge pipe 7 to adjust the discharge speed or temporarily close the discharge port.

[0030] In another embodiment, the number of crushing rollers 21 is not limited to two, but can be three or more, and the gap between adjacent crushing rollers 21 is adjustable; the shape and arrangement of the crushing blades 43 can be changed as needed; multiple scrapers 63 can be set and evenly distributed along the circumference to improve cleaning efficiency; the screen 5 can be set at an angle to promote material flow; an observation window or cleaning port can also be set on the housing 3 to facilitate monitoring of the internal condition and maintenance.

[0031] The working principle of this utility model:

[0032] Rosemary raw material is fed into the feed pipe 1, and after initial compression and crushing by two opposing rotating crushing rollers 21 in the crushing section 2, it falls into the housing 3. The second motor 42 of the crushing section 4 drives the crushing roller 41 to rotate at high speed, which in turn drives the crushing blades 43 to further crush the material. The crushed material falls onto the screen 5 under the action of gravity. Powder that meets the particle size requirements is filtered through the screen 5 and discharged from the discharge pipe 7; material that does not meet the particle size requirements remains on the screen 5 and continues to be crushed. At the same time, the third motor 66 of the scraper section 6 drives the fixed ring 61 to rotate, which drives the scraper 63 to rotate slowly along the surface of the screen 5 through the first connecting rod 62 and the second connecting rod 64, so as to clean the material blocking the screen holes in time, maintain the permeability of the screen 5, and thus improve the crushing efficiency and product quality.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
