Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a self-cleaning animal treadmill. BACKGROUND

[0002] The basic concept of a treadmill experiment is to use a treadmill as a mechanism for physical training and evaluation of small experimental animals such as rats or mice. This method plays a key role in exploring motor ability, neural function, and metabolic processes. The core of this setup is a moving conveyor belt whose surface texture helps the animal maintain grip and ensures stability while moving.

[0003] During the experiment, the hair and excrement of the experimental animals will stick to the rotating treadmill, which will affect the accuracy of the experimental results and the hygiene of the experimental environment.

[0004] Therefore, an experimental animal treadmill that can maintain the cleanliness of the conveyor belt is designed. This device is a self-cleaning animal treadmill. UTILITY MODEL CONTENTS

[0005] To overcome the problem of the treadmill being contaminated by the mixture of experimental animal excrement and hair and affecting the accuracy of the experimental results, a treadmill that can continuously clean the conveyor belt during use is proposed. The utility model specifically adopts the following technical solutions:

[0006] A self-cleaning animal treadmill includes: a box; a conveyor belt one is erected in the box through several transmission shafts one, a cleaning space is formed between the conveyor belt one and the bottom of the box, and a running space is formed between the conveyor belt one and the top of the box; a conveyor belt two is erected in the cleaning space through several transmission shafts two, a cleaning towel is sleeved on the outer wall of the conveyor belt two, the cleaning towel contacts the outer wall of the conveyor belt one, and the cleaning towel that has been contaminated with fluid in the cleaning space uniformly wipes the outer wall of the conveyor belt one when the conveyor belt one and the conveyor belt two move. The cleaning space is used to store cleaning liquid for the cleaning towel to absorb. After the cleaning towel absorbs the liquid, its volume slightly expands. When the part of the cleaning towel that has absorbed the cleaning liquid rotates with the conveyor belt two and contacts the conveyor belt one, the cleaning liquid is squeezed out of the conveyor belt one and the conveyor belt two and contacts the conveyor belt one. The cleaning towel and the outer wall of the conveyor belt one continuously scrape each other while moving, thereby achieving continuous cleaning of the outer wall of the conveyor belt one.

[0007] Further, a scraper is provided in the cleaning space along the axial direction of the transmission shaft one, and the minimum distance between the scraper and the outer wall of the conveyor belt one is less than 1 mm.

[0008] Further, the scraper and the outer wall of the conveying belt one have an included angle, the included angle between the part of the conveying belt one moving towards the scraper and the scraper is obtuse, and the included angle between the part of the conveying belt one moving away from the scraper and the scraper is acute.

[0009] Further, the scraper and the outer wall of the conveying belt one have an included angle, the included angle between the part of the conveying belt one moving towards the scraper and the scraper is obtuse, and the included angle between the part of the conveying belt one moving away from the scraper and the scraper is acute.

[0010] Further, the inner wall of the box is symmetrically provided with a plurality of shaft holes, the end of the transmission shaft one and the transmission shaft two are sleeved in the shaft holes, the rotating transmission shaft one props up the conveying belt one, and the rotating transmission shaft two props up the conveying belt two.

[0011] Further, at least one of the transmission shaft one and at least one of the transmission shaft two pass through the outer wall of the box, the outer wall of the box is connected with a motor, the rotor of the motor is sleeved with a transmission belt one at the end of the transmission shaft one extending out of the box, the rotor of the motor is sleeved with a transmission belt two at the end of the transmission shaft two extending out of the box, and the rotor drives the conveying belt one and the conveying belt two to move through the transmission belt one and the transmission belt two when rotating.

[0012] Further, the transmission shaft one and the transmission shaft two are driven to rotate by the rotor, so that the conveying belt one and the conveying belt two rotate in the same direction, the movement direction of the part of the conveying belt one and the conveying belt two contacting each other is opposite, the friction frequency of the conveying belt one and the conveying belt two is increased, and the cleaning effect of the cleaning towel on the conveying belt one is improved.

[0013] Further, the box is provided with a partition plate, the partition plate divides the cleaning space into a water tank and a collection tank, the excrement of the experimental animal is separated from the conveying belt one under the extrusion of the scraper and falls into the collection tank when the conveying belt one rotates, and the part of the conveying belt two in the water tank contacts and carries cleaning liquid when the conveying belt two rotates.

[0014] Further, the horizontal height of the transmission shaft two extending out of the box through the shaft hole is higher than the horizontal height of the liquid level of the cleaning liquid in the cleaning space.

[0015] Further, the motor is connected with a battery.

[0017] The beneficial effects of the utility model are as follows:

[0018] The system consists of two conveyor belts, a first conveyor belt and a second conveyor belt, which are in contact with each other. A cleaning cloth is also fitted over the second conveyor belt. As the second conveyor belt rotates, it contacts and wipes the outer wall of the first conveyor belt. The second conveyor belt is located within a cleaning space and comes into contact with cleaning liquid. The cleaning cloth, having absorbed the cleaning liquid, enhances the cleaning effect when it comes into contact with the first conveyor belt. When the cleaning cloth re-enters the cleaning liquid, it replenishes the liquid and removes some dirt, thus continuously cleaning the first conveyor belt. Attached Figure Description

[0027] The technical solutions of this utility model are clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] A self-cleaning animal running platform, such as Figures 1-6 As shown, it includes: a housing 1; a first conveyor belt 2, which is mounted inside the housing 1 via several drive shafts 21, forming a cleaning space 12 between the first conveyor belt 2 and the bottom of the housing 1, and a running space 11 between the first conveyor belt 2 and the top of the housing 1; a second conveyor belt 3, which is mounted in the cleaning space 12 via several drive shafts 31, and a cleaning cloth 32 is attached to the outer wall of the second conveyor belt 3. The cleaning cloth 32 is in contact with the outer wall of the first conveyor belt 2, and the cleaning cloth 32, which is contaminated with fluid in the cleaning space 12, is evenly wiped across the outer wall of the first conveyor belt 2 when the first conveyor belt 2 and the second conveyor belt 3 move. The cleaning space 12 is used to store the cleaning liquid that the cleaning cloth 32 absorbs. After absorbing the liquid, the cleaning cloth 32 expands slightly in volume. When the part of the cleaning cloth 32 that has absorbed the cleaning liquid rotates with the second conveyor belt 3 and comes into contact with the first conveyor belt 2, the cleaning liquid is squeezed out by the first conveyor belt 2 and the second conveyor belt 3 and comes into contact with the first conveyor belt 2. At the same time, the moving cleaning cloth 32 continuously scrapes the outer wall of the first conveyor belt 2, thereby achieving continuous cleaning of the outer wall of the first conveyor belt 2. Any drive shaft 21 is parallel to any drive shaft 31.

[0029] In some embodiments of this application, such as Figures 1-6 As shown, a scraper 124 is installed in the cleaning space 12 along the axial direction of the drive shaft 21. The minimum distance between the scraper 124 and the outer wall of the conveyor belt 2 is less than 1 mm. During the running process, the excrement of the experimental animals falls onto the upper part of the conveyor belt 2. Some of the excrement moves with the conveyor belt 2 to the side facing the direction of gravity and is detached by gravity and falls into the cleaning space 12. The remaining excrement sticks to the outer wall of the conveyor belt 2. The excrement accumulates on the conveyor belt 2, which affects the normal movement of the conveyor belt 2 and the experimental animals. When the excrement moves to the side of the conveyor belt 2 facing the direction of gravity and comes into contact with the scraper 124, the scraper 124 squeezes the excrement and removes it from the conveyor belt 2.

[0030] In some embodiments of this application, such as Figures 1-6As shown, there is an angle between the scraper 124 and the outer wall of the conveyor belt 2. The angle between the part of the conveyor belt 2 moving towards the scraper 124 and the scraper 124 is an obtuse angle, while the angle between the part of the conveyor belt 2 passing over and away from the scraper 124 and the scraper 124 is an acute angle. Therefore, when the excrement of the experimental animal moves from the conveyor belt 2 towards the scraper 124, the top of the scraper 124 is angled towards the excrement. Thus, when the excrement and the scraper 124 come into contact, the scraper 124 scoops up the excrement and makes it move away from the conveyor belt 2 along the outer wall of the scraper 124, thereby improving the efficiency of excrement removal.

[0031] In some embodiments of this application, such as Figures 1-6 As shown, a number of scraping teeth 1241 are linearly and uniformly distributed along the axial direction of the drive shaft 21 on the scraper 124. During the running process, experimental animals not only produce excrement but also experience hair loss, and the hair mixed in with the excrement increases its structural strength. By setting the linearly arranged scraping teeth 1241, when the scraper 124 contacts the conveyor belt 2 and removes the excrement, the hair scattered on the outside of the conveyor belt 2 and in the excrement will be firmly attached to the scraping teeth 1241 upon contact. The scraping teeth 1241 themselves can also improve the excrement removal effect by reducing the contact area between the scraper 124 and the excrement.

[0032] In some embodiments of this application, such as Figures 1-6 As shown, several shaft holes 13 are symmetrically arranged on the inner wall of the housing 1. The ends of the first drive shaft 21 and the second drive shaft 31 are sleeved in the shaft holes 13. The rotating first drive shaft 21 supports the first conveyor belt 2, and the rotating second drive shaft 31 supports the second conveyor belt 3.

[0033] In some embodiments of this application, such as Figures 1-6 As shown, at least one drive shaft 21 and at least one drive shaft 31 extend through the outer wall of the housing 1. A motor 4 is connected to the outer wall of the housing 1, and a battery 42 is connected to the motor 4. A drive belt 1 is fitted over the end of the rotor 41 of the motor 4 and the end of the drive shaft 21 extending out of the housing 1, and a drive belt 2 is fitted over the end of the rotor 41 and the end of the drive shaft 31 extending out of the housing 1. When the rotor 41 rotates, it drives the conveyor belt 2 and the conveyor belt 3 to move via the drive belts 1 and 2. By setting one rotor 41 to drive the rotation of the drive shaft 21 and the drive shaft 31, the conveyor belts 2 and 3 rotate clockwise or counterclockwise. Therefore, the contact parts of the conveyor belts 2 and 3 move in opposite directions, thereby increasing the friction frequency between the conveyor belts 2 and 3, and thus improving the cleaning effect of the cleaning cloth 32 on the conveyor belt 2.

[0034] In some embodiments of this application, such as Figures 1-6As shown, a partition 123 is installed inside the housing 1, dividing the cleaning space 12 into a water tank 121 and a collection tank 122. When the first conveyor belt 2 rotates, the excrement of the experimental animals is squeezed off the first conveyor belt 2 by the scraper 124 and falls into the collection tank 122. When the second conveyor belt 3 rotates, the portion of the second conveyor belt 3 inside the water tank 121 contacts and carries the cleaning liquid. By setting the partition 123 to separate the water tank 121 and the collection tank 122, most of the excrement that is directly scraped off will fall into the collection tank 122 instead of the water tank 121, thereby reducing the contamination of the cleaning cloth 32 and the cleaning liquid by the excrement, and thus increasing the frequency of changing the cleaning cloth 32 and the cleaning liquid.

[0035] In some embodiments of this application, such as Figures 1-6 As shown, the horizontal height of the drive shaft 31 extending from the housing 1 through the shaft hole 13 is higher than the horizontal height of the cleaning liquid level in the cleaning space 12. Although the excrement will not fall directly into the cleaning liquid, the portion that is not directly scraped off will be wiped off by the cleaning cloth 32 and enter and remain in the cleaning liquid under the rotation of the conveyor belt 3. The purpose of this arrangement is to prevent the excrement of the experimental animals from seeping out of the housing 1 through the shaft hole 13 with the cleaning liquid and contaminating the experimental environment.
