As shown in fig. 2, in the present embodiment, a fixing means is provided on the frame 8 in order to mount the ice-making drum 1. Specifically, the fixing device includes a bearing seat 14 fixedly disposed on the frame 8, and a rotating bearing 16 is disposed in the bearing seat 14. When the ice making drum is installed, the drum shaft of the ice making drum 1 penetrates through the side wall of the water tank 4 and extends to the bearing seat 14, and the drum shaft forms a rotating fit with the rotating bearing through the rotating bearing 16. It should be noted that the rotary bearing 16 may be a ball bearing or a roller bearing, but in view of the stress reliability, in order to ensure the rotational stability of the ice making drum 1, the rotary bearing 16 is preferably an angular contact ball bearing; moreover, interference fit is preferably adopted between the rotating bearing 16 and the roller shaft, and transition fit can be selected between the rotating bearing 16 and the bearing seat 14, so that the assembly and disassembly are convenient.
In another embodiment, the bearing seat 14 is further provided with a thrust bearing 15 on a side of the rotating bearing 16 away from the water tank 4; the end of the drum shaft is abutted against the thrust bearing 15 after passing through the rotary bearing 16. In this case, the thrust bearing 15 may be a thrust ball bearing or a thrust roller bearing, but in view of stress reliability, a thrust ball bearing is preferably used. Meanwhile, the thrust bearing 15 and the bearing seat 14 are also preferably in interference fit, so that the working stability of the equipment is ensured.
Referring to fig. 2 to 3, in order to form an ice layer on the surface of the ice making drum 1, a condensing agent pipe is provided inside the ice making drum 1. During the rotation of the ice making roller 1, the ice making roller 1 supplies cold energy to freeze the water contacted with the ice making roller into an ice shell through a condensing agent pipe.
In one embodiment, in order to ensure the ice layer forming efficiency, the condensing agent pipe is preferably arranged on the inner wall of the ice making roller 1 in a full-covering manner. Meanwhile, at least two condensing agent pipes are arranged in the ice making roller 1, and the condensing agent pipes can adopt a spiral structure so as to be attached to the inner wall of the ice making roller 1. At this time, each condensing agent pipe can enter the ice making drum 1 through the same pipeline and is combined into the same pipeline again at the position extending out of the ice making drum 1, so that the installation of the condensing agent pipes is convenient.
In this embodiment, the refrigerant pipe should be fixed during the rotation of the ice making drum 1. In order to ensure the stability of the condensing agent pipe, the positions of the condensing agent pipe entering and extending out of the ice making roller 1 are provided with supporting seats 13 for fixing the condensing agent pipe.
When there is only one condensing agent pipe, the condensing agent pipe can be bent into an L-shaped structure at the position where the condensing agent pipe enters and extends out of the ice making drum 1. At this time, the supporting seat 13 may adopt a pipeline structure and also be configured into an L-shaped structure, so that it is sleeved outside the condensing agent pipe.

Therefore, when two condensing agent pipes are adopted, the installation mode of the supporting seat 13 can also be set according to the above situation, and the description is omitted.
When three or more condensing agent pipes are adopted, the difference between the two pipes is only in the number of parts of the support base 13, and the actual installation manner can also refer to the situation of one or two pipes, which is not described again.
Referring to fig. 1 and 4, the ice crushing assembly includes an ice crushing wheel 7 disposed outside the ice making drum 1 and an ice crushing driving device for driving the ice crushing wheel 7 to rotate; the ice crushing wheel 7 is provided with an ice blade, and when the ice crushing driving device drives the ice crushing wheel 7 to rotate, the ice blade cuts off the ice layer on the surface of the ice making roller 1 and forms ice particles.
In this embodiment, the ice crushing wheel 7 may be disposed inside the water tank 4, and in order to prevent the ice crushing wheel 7 from being frozen on the surface, the ice crushing wheel 7 is preferably disposed above the liquid level in the water tank 4. At least two ice cutters are arranged on the circumferential surface of the ice crushing wheel 7 at intervals; thus, the ice blades sequentially cut the ice layer in turn to form ice particles. Therefore, the number of the ice blades affects the preparation efficiency of the ice particles, and the spacing of the ice blades affects the size of the ice particles. Therefore, the number of the ice blades in this embodiment can be flexibly designed according to the requirement, but considering that the number of the ice blades affects the preparation efficiency of the ice particles, the number of the ice blades should be as large as possible on the premise of meeting the production requirement (such as the requirement of the size of the ice particles).
In actual installation, the ice crushing wheel 7 can be rotatably arranged on the inner wall of the water tank 4 through a rotating shaft and a bearing. The driving device of the ice crushing wheel 7 comprises an ice crushing motor 6 fixedly arranged on the frame 8, and an output shaft of the ice crushing motor 6 can be coaxially fixed with one end of a rotating shaft of the ice crushing wheel 7 through a coupler, so that the ice crushing wheel 7 is driven to rotate.
It should be noted that in order to achieve ice particle preparation, there should be relative rotation between the ice crushing wheel 7 and the ice making drum 1 described above. Preferably, the ice crushing wheel 7 rotates in reverse synchronization with the ice making drum 1. For example, when the ice making drum 1 rotates counterclockwise, the ice crushing roller 7 may rotate clockwise in synchronization to ensure ice particle preparation efficiency.
In one embodiment, the circumferential surface of the ice making drum 1 is provided with an annular groove extending in the circumferential direction thereof; thus, during the rotation of the ice making drum 1, water is frozen in the annular groove and forms an annular ice strip. At the moment, the ice blade on the ice crushing wheel 7 is just opposite to the annular groove on the ice making roller 1, and the end part of the ice blade is embedded into the annular groove and is tangent to the inner wall of the annular groove.
In another embodiment, the ring-shaped grooves are provided at least two times on the surface of the ice making drum 1 at intervals in the axial direction of the ice making drum 1. At this time, at least two sets of ice blades (each ice blade in the same circumferential direction forms one set) are arranged on the ice crushing wheel 7 along the axial direction, and each set of ice blades respectively corresponds to each annular groove on the ice making drum 1. Therefore, the multiple groups of ice knives work simultaneously, and the ice particle preparation efficiency can be further improved.
In another embodiment, as shown in fig. 3-4, when the annular groove is provided with a plurality of sets of ice knifes, the ice crushing wheel 7 can adopt a structure form that a plurality of gear knifes are arranged side by side. At this time, the ice blades respectively form the teeth of the corresponding gear blade. During actual installation, the gear cutters are arranged side by side and fixed with each other; in order to ensure that each gear cutter rotates synchronously, the gear cutters and the rotating shaft of the ice crushing wheel 7 can be connected through a key, and the working stability of the gear cutters is fully ensured.
In another embodiment, the surface of the ice making drum 1 may be further provided with at least one longitudinal groove along the axial direction thereof, but it is preferable that the longitudinal grooves are uniformly spaced along the circumferential direction thereof in consideration of the ice particle preparing efficiency. Therefore, the longitudinal grooves are matched with the annular grooves, and a plurality of grids with uniform sizes are formed on the surface of the ice making roller 1. In the rotation process of the ice crushing wheel 7, the ice layer in each grid is cut off by the ice crushing wheel 7 through an ice blade to form ice particles; in addition, the ice blade and the ice particles are extruded, so that dehydration can be realized, and the hardness of the ice particles is greatly improved.
Referring to fig. 1, the ice crushing assembly further includes an ice scraping plate 9 disposed adjacent to the ice making drum 1, and the ice scraping plate 9 may be fixed to the frame 8 by bolts and may be disposed obliquely. The end of the ice scraping plate 9 away from the connecting part with the frame 8 extends towards the circumferential surface of the ice making drum 1, and the end can be attached to the surface of the ice making drum 1 or leave a slight space. In actual work, one end of the ice scraping plate 9, which is close to the ice making roller 1, is connected with an ice layer on the surface of the ice making roller 1; when the ice making drum 1 rotates, the ice scraping plate 9 can scrape off ice particles attached to the surface of the ice making drum 1 to separate the ice particles from the ice making drum 1.
In this embodiment, one end of the ice scraping plate 9 close to the ice making drum 1 may be set to be relatively sharp, so as to conveniently scrape off ice particles. Meanwhile, the ice scraping plate 9 should be higher than the liquid level in the water outlet tank 4, and is preferably arranged at a position close to the ice crushing wheel 7. Ideally, the ice particles formed by cutting the surface of the ice making drum 1 by the ice crushing wheel 7 should be scraped off by the ice scraping plate 9 in time, so as to prevent the ice particles from continuously adhering to the surface of the ice making drum 1 and melting or being covered by a subsequently generated ice layer.
In order to discharge the ice particles scraped off by the ice scraping plate 9 in time, an ice outlet is formed on the side wall of the water tank 4. The ice scraping plate 9 is arranged in the ice outlet in a penetrating way, and one end of the ice scraping plate, which is far away from the ice making roller 1, extends to the outside of the water tank 4 through the ice outlet. Thus, the ice scraping plate 9 is obliquely arranged, and the ice scraping plate 9 forms a sliding plate for discharging ice particles; the scraped-off ice particles will slide down the ice scraping plate 9 and out of the water tank 4.
In another embodiment, the frame 8 is further provided with a hopper 10 near the water tank 4; one end of the ice scraping plate 9, which is far away from the ice making roller 1, extends to the position of the feeding hole of the hopper 10, and the discharging hole of the hopper 10 is also provided with an ice particle distribution unit 11. In this way, the ice particles scraped and discharged by the ice scraping plate 9 automatically fall into the hopper 10 and are discharged to the ice particle dispensing unit 11 through the hopper 10.
Specifically, an ice distribution wheel 12 can be rotatably arranged at the discharge hole of the hopper 10, and a plurality of uniformly distributed material grooves are arranged on the circumferential surface of the ice distribution wheel 12; the ice particles fall into the various chutes and gradually fall into the underlying ice particle dispensing unit 11 as the ice distribution wheel 12 rotates. The ice particle dispensing unit 11 may be transported by a pipeline or a belt, but in consideration of the possibility of melting of the ice particles during transportation, the ice particle dispensing unit 11 is preferably in a pipeline transportation structure. Meanwhile, the ice particle dispensing unit 11 may adopt any pipeline transportation structure in the prior art, which is not the focus of the present invention and will not be described in detail.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict.
