DETAILED DESCRIPTION

[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference below Figure 1 and Figure 2 The pulverizer according to the first aspect of the present invention will be described in detail.

[0029] It should be noted that in the production process of five-spice powder, a grinder is needed to crush the spices to process them into powder. The powder processed by the grinder will fill the environment where the grinder is located, and the exposed bearings on the grinder will absorb these powders. Over time, the powders absorbed on these bearings will shorten the service life of the bearings.

[0030] Although lubricating the bearings with oil through oil cups can extend the service life of the bearings, the grinder will generate high-frequency vibrations as a whole during operation. As the oil cup follows the vibration of the grinder, the lubricating oil in the oil cup will shake violently, thereby forming a large number of bubbles. When the lubricating oil with bubbles is delivered to the bearings, it will affect the service life of the bearings. When a large number of bubbles accumulate at the oil delivery port of the oil cup, due to the large surface tension of the lubricating oil, these bubbles are not easy to eliminate automatically, thereby affecting the subsequent smooth passage of the lubricating oil through the oil delivery port.

[0031] According to the pulverizer of the first embodiment of the utility model, Figure 1 , including a casing 100 and an oil delivery component 200; an installation cavity 101 is formed in the casing 100, and a mounting hole is opened on the casing 100, the mounting hole extends in the vertical direction, the upper end of the mounting hole is communicated with the outside, and the lower end of the mounting hole is communicated with the mounting cavity 101, the mounting cavity 101 is used to install the bearing, and the mounting hole is located directly above the mounting cavity 101; the oil delivery component 200 includes a shell 210 and a shock absorber 220, a receiving cavity 211a and an oil passage 213a are formed in the shell 210, the lower end of the shell 210 is penetrated in the mounting hole, the oil passage 213a extends in the vertical direction, the upper end of the oil passage 213a is communicated with the receiving cavity 211a, and the lower end of the oil passage 213a is communicated with the installation cavity 101, the receiving cavity 211a is used to contain lubricating oil, the shock absorber 220 is arranged in the receiving cavity 211a, and the density of the shock absorber 220 is less than or equal to the density of the lubricating oil.

[0032] It can be understood that since the density of the shock absorber 220 is less than or equal to the density of the lubricating oil, when the lubricating oil is contained in the accommodating chamber 211a, the shock absorber 220 can float or suspend in the lubricating oil; when the pulverizer of this embodiment is working, the pulverizer as a whole will produce high-frequency vibration, and accordingly, the casing 100 will drive the oil delivery component 200 to vibrate. During the vibration of the oil delivery component 200, the lubricating oil in the accommodating chamber 211a will shake, and the arrangement of the shock absorber 220 in the accommodating chamber 211a enables part of the kinetic energy of the lubricating oil to be transferred to the shock absorber 220 during the shaking of the lubricating oil, thereby reducing the overall shaking of the lubricating oil, and further reducing the generation of bubbles inside the lubricating oil.

[0033] In a specific embodiment of the present invention, the shock absorbing member 220 includes sponge.

[0034] It can be understood that the texture of the sponge is relatively soft. After the sponge is soaked in lubricating oil, the sponge fibers of the sponge can be filled with the lubricating oil. During the shaking of the lubricating oil, each sponge fiber of the sponge can fully absorb the kinetic energy of the lubricating oil to reduce the shaking degree of the lubricating oil, thereby reducing the generation of bubbles in the lubricating oil.

[0035] In another specific embodiment of the present invention, the shock absorbing member 220 includes a foam ball.

[0036] In some embodiments of the present invention, reference Figure 1 The housing 210 includes a shell 211, a shell cover 212 and an oil nozzle 213. An accommodating chamber 211a is formed in the shell 211. The shell 211 is in the shape of a funnel whose cross-sectional dimension gradually decreases from top to bottom, and the accommodating chamber 211a is in the shape of a funnel whose cross-sectional dimension gradually decreases from top to bottom. A cavity opening connecting the outside and the accommodating chamber 211a is formed at the upper end of the shell 211. The shell cover 212 is arranged at the cavity opening. The shell cover 212 is detachably connected to the shell 211 and is used to close the cavity opening. An oil passage 213a is formed in the oil nozzle 213. The upper end of the oil nozzle 213 is connected to the lower end of the shell 211, and the lower end of the oil nozzle 213 is detachably penetrated into the mounting hole.

[0037] Furthermore, the lubricating oil in the accommodating chamber 211 a can flow through the oil passage 213 a and drip onto the bearing of the mounting chamber 101 .

[0038] It is understandable that when installing the oil delivery assembly 200 on the housing 100 , the staff can insert the oil nozzle 213 of the oil delivery assembly 200 into the installation hole, so that the oil passage 213 a can communicate with the installation cavity 101 .

[0039] It is understandable that when the oil delivery assembly 200 needs to be supplemented with lubricating oil, the staff can open the shell cover 212 so that the accommodating chamber 211a can be connected to the outside through the cavity opening. At this time, the staff can input lubricating oil into the accommodating chamber 211a.

[0040] In some embodiments of the utility model, in order to achieve a detachable connection between the oil nozzle 213 and the casing 100, the outer side surface of the oil nozzle 213 is provided with an external thread, and the wall of the mounting hole is provided with an internal thread that matches the external thread, and the external thread is meshed with the internal thread to achieve a detachable connection between the oil nozzle 213 and the wall of the mounting hole.

[0041] In order to facilitate the installation or removal of the shell cover 212, in a further embodiment of the present utility model, reference is made to Figure 1The oil delivery assembly 200 also includes a connecting rod 230, which is vertically extended. The connecting rod 230 is inserted into the oil passage 213a and is connected to a part of the structure of the inner wall of the oil nozzle 213. An oil gap 213b is formed between the inner wall of the oil nozzle 213 and the connecting rod 230; the upper end of the connecting rod 230 passes through the shell cover 212, and the shell cover 212 is detachably mounted on the connecting rod 230.

[0042] It is understandable that when the staff needs to remove the shell cover 212, the staff can slide the shell cover 212 upward along the connecting rod 230 so that the opening of the accommodating chamber 211a can be opened; when the staff needs to install the shell cover 212, the staff can put the shell cover 212 on the connecting rod 230 and drive the shell cover 212 to slide downward along the connecting rod 230 so that the shell cover 212 can move to the opening of the accommodating chamber 211a, thereby achieving the closure of the opening of the accommodating chamber 211a.

[0043] It can be understood that since an oil gap 213b is formed between the inner wall of the oil nozzle 213 and the connecting rod 230, the lubricating oil in the accommodating chamber 211a needs to pass through the oil gap 213b and the oil channel 213a in sequence to enter the installation chamber 101, and the cross-sectional size of the oil gap 213b is smaller than the oil channel 213a, so that the lubricating oil in the accommodating chamber 211a can be input into the installation chamber 101 more slowly, so as to extend the oil delivery time of the oil delivery component 200 after a single refueling.

[0044] It should be noted that the oil delivery component 200 is connected to the casing 100 through the oil nozzle 213, and the cross-sectional dimension of the oil nozzle 213 is small, and the oil nozzle 213 is a hollow structure. The strength of the oil nozzle 213 is low. During the operation of the grinder, the casing 100 and the oil delivery component 200 are subjected to high-frequency vibration, and the oil nozzle 213 is prone to deformation and damage.

[0045] It is understandable that, in the pulverizer of this embodiment, the lower end of the connecting rod 230 is inserted into the oil passage 213a of the oil nozzle 213, so that the connecting rod 230 can internally support the oil nozzle 213 to enhance the strength of the oil nozzle 213.

[0046] In a further embodiment of the present invention, reference Figure 2 The edge of the shell cover 212 is provided with a clamping portion 212a that abuts against the outer wall of the shell body 211.

[0047] It can be understood that the provision of the clamping portion 212a makes the connection between the shell cover 212 and the shell body 211 tighter, so as to reduce the probability of the lubricating oil splashing out of the accommodating cavity 211a.

[0048] It should be noted that after the shell cover 212 closes the opening of the accommodating cavity 211 a , the shell cover 212 needs to be locked and fixed to prevent the shell cover 212 from falling off during vibration.

[0049] Based on the above problems, in a further embodiment of the present invention, reference is made to Figure 1 The oil delivery assembly 200 further includes a threaded fastener 240, which is threadedly sleeved on the connecting rod 230, and the upper and lower ends of the shell cover 212 are respectively in contact with the threaded fastener 240 and the edge of the cavity.

[0050] Furthermore, when the shell cover 212 is located at the opening of the accommodating cavity 211 a , the staff can tighten the threaded fastener 240 downward so that the threaded fastener 240 can cooperate with the shell body 211 to lock and limit the shell cover 212 in the vertical direction.

[0051] Specifically, the threaded fastener 240 is a locking nut.

[0052] In order to prevent the locking nut from loosening on the connecting rod 230, in a further embodiment of the present invention, Figure 1 The conveying assembly further includes a locking nut 260 , which is threadedly sleeved on the connecting rod 230 and abuts against an end of the locking nut that is away from the shell cover 212 .

[0053] In some embodiments of the present invention, reference Figure 1 The oil delivery assembly 200 further includes a plurality of baffles 250, which are disposed in the accommodating chamber 211a and are circumferentially spaced around the connecting rod 230. The opposite ends of the baffles 250 are respectively connected to the connecting rod 230 and the side wall of the accommodating chamber 211a.

[0054] It can be understood that the partition 250 can divide the accommodating cavity 211a into multiple accommodating areas, so that the lubricating oil can be accommodated in each accommodating area respectively, and the amount of lubricating oil in each accommodating area is relatively small, so that the lubricating oil in each accommodating area shakes less, thereby reducing the probability of bubbles generated in the lubricating oil.

[0055] The five-spice powder production line according to the second embodiment of the utility model comprises the grinder according to the first embodiment of the utility model.

[0056] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
