When conducting experiments on grain seeds such as wheat, rice and soybeans, a grain counter is needed to select an appropriate number of seeds.

[0003] A search revealed a Chinese patent for a multi-row ordered automatic feeding device for a oscillating counting machine, publication number CN203568030U. The device includes a frame with a conveyor belt for conveying medicine bottles on the frame. A counting turntable is located above the conveyor belt, and the counting turntable has a plurality of counting holes evenly distributed on it.

[0004] The above-mentioned device has a simple structure, is easy to operate, convenient to use, runs smoothly, is easy to clean and maintain, and is durable. It greatly improves labor productivity and avoids human pollution caused by manual counting and filling.

[0005] However, adjusting the counting efficiency by opening multiple counting holes on the counting disc is a relatively simple structure, making it difficult to adjust the number of counting holes as needed, resulting in poor flexibility in use. Furthermore, shaking the seeds into the feeding hole by swaying may cause two seeds to stack or seeds to get stuck on the counting disc, affecting the accuracy of feeding. Utility Model Content

[0006] The purpose of this invention is to provide an automatic feeding device for a seed counter, which can effectively solve the problems in the prior art where it is difficult to adjust the number of counting holes as needed, the flexibility of use is poor, and the shaking of seeds into the feeding holes by swaying may cause two seeds to stack or seeds to get stuck on the counting plate.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic feeding device for a counting machine includes a swing counting frame body, a mounting bracket is fixedly connected to the rear end of the swing counting frame body, a swing rotating rod is rotatably mounted through the upper and lower ends of the swing counting frame body at the center position, and a counting turntable is mounted on the top end of the swing rotating rod through a mounting block.

[0009] A plurality of counting holes are provided through the upper and lower ends of the counting turntable, and the counting holes are divided into three groups on the counting turntable. Each group of counting holes is equidistantly arranged on the counting turntable. The counting turntable has a movable groove inside, and a baffle that adapts to the shape of the counting holes is slidably installed inside the movable groove. A slider is fixedly connected to the top of the baffle near the outer position, and a sliding groove that adapts to the slider is provided on the top surface of the counting turntable. A feeding port that adapts to the counting holes is provided at the front position of the bottom end of the swing counting frame body.

[0010] Preferably, an adjusting bolt is threaded through the upper and lower ends of the slider, and the bottom end of the adjusting bolt abuts against several turntables.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Combination Figures 1-4 An automatic feeding device for a counting machine includes a swing counting frame body 1, a mounting bracket 2 fixedly connected to the rear end of the swing counting frame body 1, a swing rotating rod 3 rotatably mounted at the center of the upper and lower ends of the swing counting frame body 1, and a counting turntable 4 mounted on the top end of the swing rotating rod 3 via a mounting block.

[0027] See Figure 2 and Figure 3Furthermore, several counting holes 5 are provided at the upper and lower ends of the counting turntable 4, and the counting holes 5 are divided into three groups on the counting turntable 4. Each group of counting holes 5 is equidistantly arranged on the counting turntable 4. An movable groove 10 is provided inside the counting turntable 4. A baffle 6 that is adapted to and matches the shape of the counting holes 5 is slidably installed inside the movable groove 10. A slider 7 is fixedly connected to the top of the baffle 6 near the outer position. A sliding groove 8 that is adapted to and matches the slider 7 is provided on the top surface of the counting turntable 4. A feeding port 16 that is adapted to and matches the counting holes 5 is provided at the bottom front position of the swing counting frame body 1. Adjusting bolts 9 are threadedly connected to the upper and lower ends of the slider 7. The bottom end of the adjusting bolts 9 abuts against the counting turntable 4. A gap is left between the outer ring of the counting turntable 4 and the inner ring of the swing counting frame body 1. A gap is left between the swing rotating rod 3 and the swing counting frame body 1.

[0028] Specifically, the counting turntable 4 is controlled to rotate and swing clockwise, causing the seeds to fall into the counting holes 5. The seeds are then conveyed to the feeding port 16 by the rotation of the counting turntable 4. Once the turntable 4 reaches the feeding port 16, the seeds in the counting holes 5 will fall downwards through the feeding port 16, completing the automatic feeding process. Before feeding, the adjusting bolt 9 can be loosened to lock the baffle 6. Then, by pushing the baffle 6 to slide within the movable groove 10, the number of counting holes 5 can be adjusted in batches. That is, when the baffle 6 rotates to the counting hole 5, it will block the counting hole 5, preventing seeds from falling into the counting hole 5. This allows for adjustments based on the number of seeds, providing high flexibility in use.

[0029] Example 2

[0030] See Figure 2 and Figure 4 Furthermore, based on Embodiment 1, a partition plate 12 is fixedly installed on the upper part of the interior of the oscillating counting frame body 1 via a support plate 11. The bottom end of the partition plate 12 has an installation groove, and an installation plate 13 is movably installed inside the installation groove. A rubber sweeping plate 14 is attached to the bottom end of the installation plate 13. The bottom surface of the rubber sweeping plate 14 is in contact with the top surface of the counting turntable 4. An installation bolt 15 is fixedly installed on the lower part of the partition plate 12 away from the center point of the oscillating counting frame body 1. Installation holes that are compatible with the installation bolt 15 are provided on both sides of the installation plate 13. An installation nut is threaded on the outer ring of the installation bolt 15, and the inner side of the installation nut is in contact with the outer side of the installation plate 13. The rubber sweeping plate 14 is flexible and is detachably connected to the installation plate 13 and the partition plate 12 via the installation bolt 15.

[0031] Specifically, during the seed conveying process, the rubber broom 14, by adhering to the top surface of the counting turntable 4, can block seeds that have not fully entered the counting hole 5, preventing them from entering the feeding port 16 as the counting turntable 4 rotates, thereby improving feeding accuracy. At the same time, the rubber broom 14 can be detachably mounted on the partition plate 12 via the mounting plate 13 and mounting bolts 15, so that it can be replaced after long-term use to prevent it from losing its blocking function. In addition, the rubber broom 14 has soft contact with the seeds, which can reduce the probability of damage.

[0032] In actual operation, the swing counting frame body 1 can be installed in a suitable position using the mounting bracket 2, and the swing rotating rod 3 can be connected to the drive shaft of the external swing motor as needed. After ensuring safety, the seeds of grains such as wheat and rice can be placed on the side away from the feed port 16. Then, the drive shaft of the swing motor can be controlled to rotate clockwise to drive the swing rotating rod 3 to rotate, thereby causing the counting turntable 4 to rotate clockwise, so that the seeds fall into the counting hole 5 and are conveyed towards the feed port 16 through the rotation of the counting turntable 4. After rotating to the feed port 16, the seeds in the counting hole 5 will fall downward through the guide of the feed port 16 to complete the automatic feeding process.

[0033] Before feeding, the adjusting bolt 9 can be loosened to engage the locking of the baffle 6. Then, by pushing the baffle 6 to slide in the movable groove 10, the number of counting holes 5 can be adjusted in batches. That is, when the baffle 6 is rotated to the counting hole 5, it will block the counting hole 5, so that the seeds will not fall into the counting hole 5, so as to adjust according to the number of seeds, which is highly flexible in use.

[0034] During seed conveying, the rubber broom 14, by adhering to the top surface of the counting turntable 4, can block seeds that have not fully entered the counting hole 5, preventing them from entering the feeding port 16 as the counting turntable 4 rotates, thereby improving feeding accuracy. At the same time, the rubber broom 14 can be detachably mounted on the partition plate 12 via the mounting plate 13 and mounting bolts 15, so that it can be replaced after long-term use to prevent it from losing its blocking function. In addition, the rubber broom 14 has soft contact with the seeds, which can reduce the probability of damage.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
