[0002] The toad specification grading device is a device for grading the size, weight or other external characteristics of toads (especially frogs or other amphibians).

[0003] Bingtian is a traditional Chinese medicine recorded in Chinese Pharmacopoeia (Part I), which is the dried secretion of Chinese toad Bufobufo gargarizans Cantor or black-rimmed toad Bufomelanostictus Schneider. In recent years, due to serious destruction of amphibian environment and reduction of toad habitat, toad population resources are decreasing. In order to increase toad population resources, artificial breeding of toads must be relied on. Due to individual differences of toads, toads of the same batch are prone to size difference after artificial breeding for a certain period of time, that is, the body weight of toads is differentiated, some toad individuals are large, and some toad individuals are small. Toads have the habit of eating small individuals, and large individuals will prey and kill small individuals that can be swallowed. In order to reduce the cannibalism of toads, different size toads need to be classified and managed during breeding, so that toads in the same breeding pond are uniform in size. The existing toad size classification is mostly completed by manual selection, and toads with similar external size are manually put into cages, which is time-consuming and laborious and prone to errors.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] First embodiment:

[0023] like Figures 1-4 As shown, the toad grading device provided by this utility model includes: a transmission mechanism 100 and a grading mechanism 200. The grading mechanism 200 has several components located on both sides of the transmission mechanism 100. The transmission mechanism 100 includes a transmission belt 101, which is a structure found in the prior art. A weight sensor is installed inside the transmission belt 101 and is controlled by an external computer. The grading mechanism 200 includes a collection box 201. A load-bearing plate 205 is provided on one side of the collection box 201. A motor 206 is installed on the load-bearing plate 205. A rotating shaft 207 is provided at the top of the motor 206. The motor 206 is rotatably connected to a scraper 208 through the rotating shaft 207. The motor 206 is controlled by an external computer to open and close. In use, the operator places the toad on the transmission belt 101 from one side and starts the transmission belt 101. The transmission belt 101 moves the toad forward. During the process, the weight sensors at the bottom of the conveyor belt 101 start working. There are multiple weight sensors that match the number of grading mechanisms 200. The weight sensors divide the conveyor belt 101 into different weight specification areas. The weight sensors automatically weigh the toads on the conveyor belt 101 and transmit the data to the computer interface. The data is compared with the preset standard weight value, upper and lower limits and other parameters. Then, the toads of different weights are identified and sorted according to each preset weight specification. The computer and the motor 206 are interconnected. When the toads are transported to different weight specification areas and match the weight planned by the external computer, the computer controls the motor 206 on that side to work. The motor 206 drives the scraper 208 to rotate through the rotating shaft 207, so that the scraper 208 scrapes the toads that meet the weight standard on the conveyor belt 101 into the collection box 201, thus completing the specification grading of the toads.

[0024] This invention uses a weight sensor to automatically weigh the toads on the conveyor belt 101 and starts the motor 206 so that the scraper 208 scrapes the toads that meet the weight standard on the conveyor belt 101 into the collection box 201, thus completing the size grading of the toads. Compared with the existing toad size grading device, it does not require manual selection of toads for classification and grading, thus improving the efficiency and automation level of toad grading.

[0025] Second embodiment:

[0026] like Figure 1As shown, the top end of the transmission belt 101 is provided with a baffle 102 on both sides, and the top end of the baffle 102 is provided with a screen 103. When the toad is transported on the transmission belt 101, the toad is a living thing, and at this time the toad is in a living state. The toad may jump off the transmission belt 101. At this time, the two side baffles 102 form a relatively sealed environment for the transmission belt 101, and fix the movement range of the toad. The top screen 103 allows the worker to see the state of the toad on the transmission belt 101.

[0027] By fixing the movement range of the toad on both sides of the transmission belt 101 by the baffle 102, the toad is prevented from jumping out of the transmission belt 101, and the grading efficiency of the toad is improved.

[0028] Third embodiment:

[0029] As shown in Figure 1 , Figure 2 , Figure 3 , the top end of the collection box 201 is provided with a rotating rod 202, and the rotating rod 202 is rotatably connected to a cover plate 203. The cover plate 203 is attached to the opening of the collection box 201. When the collection box 201 completes the grading and collection of toads, the cover plate 203 is rotated by the rotating rod 202 to be attached to the collection box 201 as shown in Figure 3 , so that the cover plate 203 and the collection box 201 form a sealed environment to prevent the toad from jumping out of the collection box 201.

[0030] By closing the cover plate 203, the collection box 201 forms a sealed environment to prevent the toad from jumping out of the collection box 201 after grading, thereby facilitating subsequent classification, transportation or other processing steps.

[0031] Fourth embodiment:

[0032] As shown in Figure 1 , Figure 2 , Figure 3 , a plurality of through holes 204 are provided on the cover plate 203. When the cover plate 203 is closed, the top through hole 204 supplies oxygen to the collection box 201 to prevent the toad from suffocating due to lack of air circulation in the collection box 201.

[0033] Fifth embodiment:

[0034] As shown in Figure 4 , recesses 104 are provided at the connection between the transmission belt 101 and the scraper 208 on both sides, and an arc-shaped groove 209 is provided at the opening of the collection box 201. When the scraper 208 is scraped on the transmission belt 101 and retracted, the recesses 104 on the side of the transmission belt 101 cooperate with the arc-shaped groove 209 at the opening of the collection box 201, so that the movement trajectory of the scraper 208 is fixed and will not hinder the movement of the scraper 208.

[0035] In use, the staff places the toad on the conveying belt 101 from one side of the conveying belt 101, starts the conveying belt 101, and the conveying belt 101 drives the toad to be conveyed forward, and the weight sensor at the bottom end of the conveying belt 101 starts to work in the conveying process, the weight sensor is provided with a plurality of matching numbers of the grading mechanism 200, and the weight sensor divides the conveying belt 101 into different weight specification areas, the weight sensor automatically weighs the toad on the conveying belt 101, and transmits data to the computer interface, compares with the pre-set standard weight value, upper and lower limit value and other parameters, and then distinguishes and sorts the toads of different weights according to the set each weight specification, the computer and the motor 206 are connected with each other, when the toad is transported to the different weight specification area and matches the weight planned by the external computer, the computer controls the motor 206 on the side to work, the motor 206 drives the scraper 208 to rotate through the rotating shaft 207, so that the scraper 208 scrapes the toad meeting the weight standard on the conveying belt 101 into the collecting box 201, and the specification grading of the toad is completed, when the collecting box 201 completes the grading and collection of the toad, the cover plate 203 is rotated into the sealing environment shown in the drawing through the rotating rod 202, the cover plate 203 is attached to the collecting box 201 to form a sealed environment, and the toad is prevented from bouncing out of the collecting box 201.
