Description

Technical Field

[0001] This utility model belongs to the field of animal dental medical device technology, specifically relating to a handheld tooth grinding device for animal husbandry. Background Technology

[0002] Dental health problems in equines, such as horses, mules, and donkeys, are more common in older individuals. This is due to their anatomical feature—the maxillary dental arch being wider than the mandibular dental arch—and their herbivorous diet involving extremely frequent chewing movements, leading to continuous and severe wear on the tooth abrasive surfaces. Chewing is crucial for the digestive process; therefore, the integrity of tooth morphology directly affects the efficiency of food grinding and subsequent digestion and absorption.

[0003] As equines age, various morphological abnormalities often appear in their teeth. Adults are prone to developing sharp, pointed teeth, while older animals commonly develop wavy teeth with uneven, undulating chewing surfaces, and some may exhibit excessively long teeth. The treatment of the terminal molars, located deep within the oral cavity, is particularly challenging due to their location and extremely limited operating space. Currently, veterinary clinical practice primarily relies on traditional manual tools such as mallets and dental shears for tooth shaping. However, these tools suffer from significant drawbacks when dealing with terminal molars, including difficulty in operation, insufficient precision, and low efficiency, making effective and safe morphological correction difficult.

[0004] If the aforementioned problems are not addressed, especially the issue of terminal molars, which cannot be corrected promptly and effectively, it will severely impair the animal's chewing function. Insufficient chewing directly leads to a significant decrease in food digestion efficiency, which in turn induces oral inflammation, anterior digestive tract diseases, and even severe intestinal constipation, seriously affecting animal welfare and usability. Therefore, designing a new dental instrument to efficiently and conveniently address abnormal tooth shapes such as sharp, wavy, and elongated teeth in equines has become an urgent need in the veterinary industry. Utility Model Content

[0005] In view of the shortcomings of existing trimming methods and traditional manual tools in the background art, this utility model provides a handheld tooth grinding device for animal husbandry.

Detailed Implementation

[0020] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figure 1-4 Based on the actual assembly and use process, the present invention will be further explained through two embodiments.

[0021] In the following examples, the handheld motor body is an outsourced product. We take the S1J-DY-10 high-speed electric grinder from Jiangsu Dayi Tools Co., Ltd. as an example. This equipment has a rated input power of 135W and an idle speed of 31000 r / min. Depending on the usage scenario, we can choose either a lithium battery-powered type or an AC-powered type to meet operational needs in different environments. Example 1

[0022] As attached Figure 1-4 As shown, a handheld animal teeth grinding device includes a handheld motor body 1, a transmission tube assembly 2, a straight grinding file head 3, and grinding parts 4. The transmission tube assembly 2 includes a main shaft tube 201 and a steel wire shaft 202. The main shaft tube 201 is 25cm long and is threadedly connected to the handheld motor body 1. A spring 203 passes through the outside of the steel wire shaft 202, and both are housed inside the main shaft tube 201. This provides radial support to the steel wire shaft 202, reducing its swaying or offset during high-speed rotation and ensuring the stability of power transmission. One end of the steel wire shaft 202 is connected to the motor output shaft via a locking nut 11, and the other end is equipped with a connector 204. The outer housing 301 of the straight grinding file head 3 is connected to the main shaft tube 201 by a thread. Inside, a first rotating shaft 303 is provided through a first bearing 302 and a second rotating shaft 305 is provided through a second bearing 304. The two shafts are arranged vertically and have a first bevel gear 306 and a second bevel gear 307 meshing at their ends. One end of the first rotating shaft 303 is provided with a plug interface 308, which mates with the plug interface 204 of the steel wire shaft 202. The other end of the second rotating shaft 305 is connected to the grinding part 4.

[0023] During assembly, the wire shaft 202 and spring 203 are inserted into the main spindle tube 201, and the main spindle tube 201 is threadedly connected to the handheld motor body 1. The end of the wire shaft 202 is pressed and fixed onto the motor output shaft of the handheld motor body 1 through the locking nut 11; the plug interface 308 is connected to the plug connector 204; the outer shell 301 of the straight grinding sharp file head 3 is connected to the main spindle tube 201, completing the assembly. In this embodiment, the grinding part 4 is a diamond abrasive disc or a rotary file. The appropriate grinding tool is selected according to the actual grinding operation requirements to meet the grinding needs of teeth in different positions. During operation, the handheld motor body 1 is started, and the power is transmitted to the first rotating shaft 303 through the wire shaft 202. The second rotating shaft 305 and the grinding part 4 are driven through the meshing of the bevel gear. The operator holds the main spindle tube 201 with one hand and the handheld motor body 1 with the other hand through the anti-slip grip 5 to perform precise grinding of the front middle sharp teeth. Example 2

[0024] This addresses the issue of the steel wire shaft causing the spring to rotate and rub against the inner wall of the spindle tube, resulting in heat generation and making it impossible for the operator to hold the spindle tube.

[0025] As attached Figure 1 and 2 As shown, based on Example 1, we solve the operational difficulties caused by heat generation by adding a sleeve and an anti-slip grip design. The specific implementation plan is as follows: During assembly, the sleeve 6 is installed inside the spindle tube 201. After assembly, one end of the sleeve 6 abuts against the outer ring of the first bearing 302, and the other end abuts against the contact surface of the handheld motor body 1; it is also fixed by the first fixing nut 7 and the second fixing nut 8. In addition, an anti-slip grip 5 is provided on the outside of the spindle tube 201. The sponge anti-slip grip 5 is made of sponge material with an anti-slip texture on the surface. This can effectively insulate heat and provide a good grip, ensuring that the operator's hand is comfortable during long-term grinding and avoiding operational inconvenience caused by friction and heat generation.

[0026] Therefore, through the above two aspects of optimized design, frictional heat is effectively reduced, making the grinding process efficient and precise, while improving operating comfort and extending the service life of the equipment.
