Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product transportation, and specifically to an agricultural product transportation device. Background Art

[0002] Traditional Chinese medicine mainly originated in China. It is a medicine used for preventing, diagnosing, and treating diseases or regulating the human body functions under the guidance of traditional Chinese medicine theory. Most of them are plant medicines, and there are also animal medicines, mineral medicines, and some chemical and biological product medicines. Traditional Chinese medicine is divided into patent medicines and crude drugs according to the processing technology. Herbal medicines are made from plant extracts.

[0003] For example, the Chinese patent with the publication number CN216271372U discloses a conveying device for cutting Chinese herbal medicines, which relates to the technical field of Chinese herbal medicine processing and transportation. It includes a chassis, and a groove is opened on the upper surface of the chassis. Two fixing plates are fixedly installed on the left side of the upper surface of the chassis. For this conveying device for cutting Chinese herbal medicines, after pressing the herbal Chinese medicine, the servo motor rotates counterclockwise to drive the second driving wheel to rotate. The second driving wheel drives the first driving wheel and the first gear to rotate counterclockwise through the transmission belt, driving the first roller shaft and the first conveyor belt to rotate. When the first gear rotates counterclockwise, it drives the second gear to rotate clockwise, thereby driving the second roller shaft and the second conveyor belt to rotate synchronously clockwise. The herbal Chinese medicine is conveyed to the left by the first conveyor belt and the second conveyor belt, improving the pressing and conveying effect of the device. Therefore, a cutting device is better arranged on the left to cut the herbal Chinese medicine, avoiding the problem of poor conveying and pressing effects during cutting.

[0004] The traditional conveyor belt lacks dynamic cloth regulating, and materials are prone to form local accumulations due to gravity or uneven feeding, resulting in unbalanced conveyor belt load, running jams, and even equipment failures. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an agricultural product transportation device aiming at the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is as follows: An agricultural product conveying device includes a bottom plate. Two first vertical plates are fixedly connected to the top of the bottom plate. A mesh belt conveyor is arranged between the two first vertical plates. A number of mesh plates are arranged inside the mesh belt conveyor. The mesh plates are provided to allow air circulation and facilitate the falling of dust. An anti-accumulation mechanism is arranged inside the mesh belt conveyor. The anti-accumulation mechanism includes a fixing plate. The fixing plate is fixedly connected to the front of the first vertical plate. An electric telescopic rod is fixedly connected to the top of the fixing plate. A cross plate is fixedly connected to the top of the electric telescopic rod. A number of bumps are fixedly connected to the top of the cross plate. When the bumps rise, they will touch the mesh belt conveyor to cause the Chinese herbal medicines on the mesh plates to vibrate up and down, so that the dust will fall from the holes inside the mesh plates. This not only cleans the dust but also enables the Chinese herbal medicines to be evenly distributed during the conveying process, avoiding accumulation or blockage, thereby improving the stability and smoothness of the conveying.

[0007] Preferably, support plates are respectively fixedly connected to the tops of the two first vertical plates. A sliding rod is fixedly connected between the two support plates. Four sliding sleeves are movably sleeved on the outer wall of the sliding rod. The four sliding sleeves are divided into two groups. Each two sliding sleeves are fixedly connected by a fixing rod. A support rod is hinged between the sliding sleeve and the cross plate.

[0008] Preferably, connecting plates are respectively fixedly connected to one ends of the four sliding sleeves. An elastic rod is fixedly connected to the bottom of the connecting plate. A combing plate is fixedly connected to the bottom of the elastic rod. The bottom of the combing plate is in contact with the top of the mesh plate. The rising of the support rod will drive the sliding sleeve to move on the sliding rod. Thus, the movement of the sliding sleeve will drive the connecting plate to move, and the movement of the connecting plate will drive the elastic rod to move. The movement of the elastic rod will drive the movement of the combing plate, so that the Chinese herbal medicines on the mesh belt conveyor can be evenly turned over, ensuring that the Chinese herbal medicines will not accumulate locally during the conveying process and avoiding the problems of unsmooth conveying or difficult cleaning caused by accumulation.

[0009] Preferably, an anti-blocking mechanism is arranged on the top of the bottom plate. The anti-blocking mechanism includes a vertical rod. The vertical rod is fixedly connected to the bottom of the cross plate. A first slider is fixedly connected to the bottom of the vertical rod. A square plate is arranged at the bottom of the first slider. A number of brushes are fixedly connected to the bottom of the square plate. The Chinese herbal medicines blocking the mesh holes inside the mesh plate can be pushed out and cleaned by the downward movement of the brushes.

[0010] Preferably, a first sliding groove is formed on the square plate. The first slider is slidably connected inside the first sliding groove. A first spring is fixedly connected between one side of the first slider and the inner wall of the first sliding groove.

[0011] Preferably, a first resistance block is fixedly connected to the back of the square plate, and a second resistance block is fixedly connected to the front of the first vertical plate. The first resistance block contacts the second resistance block. When the square plate descends to a certain position, the first resistance block contacts the second resistance block, so that the first resistance block is displaced under the action of the second resistance block, causing the brush at the bottom of the square plate to be slightly displaced, thereby improving the cleaning effect of the mesh inside the screen plate, making the mesh more unobstructed, and facilitating the falling of dust, thereby avoiding the subsequent corruption of Chinese herbal medicines due to dust.

[0012] Preferably, a uniform feeding mechanism is provided on the top of the bottom plate, and the uniform feeding mechanism includes two second vertical plates, a feeding plate is rotatably connected between the two second vertical plates, a second slide groove is provided on the front side of the first vertical plate, a second slider is slidably connected inside the second slide groove, the second slider is rotatably connected to the back of the feeding plate, a second spring is fixedly connected between the second slider and the inner wall of the second slide groove, a resistance rod is fixedly connected to one end of the combing plate, a wavy resistance plate is fixedly connected to one end of the feeding plate, the resistance rod is in contact with the wavy resistance plate, and the combing plate will drive the resistance rod to move back and forth when it moves back and forth, and the contact action of the resistance rod and the wavy resistance plate makes the wavy resistance plate slightly shake up and down, thereby driving the feeding plate to shake slightly, ensuring that the agricultural products can fall onto the conveyor belt evenly and stably.

[0013] Preferably, a third slide groove is provided on the right side of the wavy resistance plate, and a third sliding block is slidably connected to the inside of the third slide groove, and a scraper is fixedly connected to the top of the third sliding block, and the scraper is in contact with the blanking plate, and a third spring is fixedly connected between the third sliding block and the inner wall of the third slide groove, and a push rod is fixedly connected to the top of the resistance rod, and the push rod is in contact with the back of the third sliding block, and the third sliding block is pushed forward by the forward and backward movement of the push rod, thereby driving the scraper to move, and some residual Chinese herbal medicine on the blanking plate can be scraped off by the scraper, and when the push rod moves backward, the third sliding block will be reset under the elastic action of the third spring, thereby realizing the reciprocating scraping of the scraper, thereby promoting the uniform discharge of Chinese herbal medicines.

[0014] The present invention adopts the above technical solution to bring the following beneficial effects:

[0015] 1. This agricultural product conveying equipment makes the Chinese herbal medicines on the mesh plate shake by the up and down movement of the protrusions, so that the Chinese herbal medicines are evenly distributed during the conveying process to avoid accumulation or blockage, thereby improving the stability and smoothness of the conveying. The forward and backward movement of the combing plate can evenly turn the Chinese herbal medicines on the mesh belt conveyor to ensure that the Chinese herbal medicines will not be locally accumulated during the conveying process, thereby improving the conveying efficiency of the Chinese herbal medicines.

[0016] 2. This agricultural product conveying device can promote the falling of dust when the mesh plate vibrates up and down. The inside of the mesh plate is continuously cleaned by the up-and-down movement of the brush, preventing the residue of Chinese herbal medicines from clogging the mesh holes, ensuring the smoothness of the mesh holes, enabling the mesh belt to better conform to the vibrating action, enhancing the vibration effect of Chinese herbal medicines, promoting the falling of dust, and the brush has a slight displacement during the cleaning process, improving the cleaning effect, effectively avoiding the influence of mesh hole blockage on the falling of dust, and ensuring the cleaning effect of Chinese herbal medicines.

[0017] 3. This agricultural product conveying device ensures that Chinese herbal medicines fall evenly and stably onto the conveyor belt by the uniform swinging of the feeding plate when the Chinese herbal medicines are falling, avoiding local over-thick accumulation, reducing the phenomenon that the dust is squeezed to the upper layer by the lower-layer Chinese herbal medicines being pressed, and at the same time, the scraper effectively removes the residual materials on the feeding plate, ensuring that Chinese herbal medicines fall evenly onto the mesh belt conveyor, thus avoiding the influence of local accumulation on the falling of dust and improving the conveying efficiency and quality of Chinese herbal medicines.

[0018] 4. This agricultural product conveying device can promote the loosening of dust on Chinese herbal medicines to a certain extent by the uniform swinging of the feeding plate when the Chinese herbal medicines are falling, prompting the dust on the surface and in the interlayers of Chinese herbal medicines to loosen, thereby further improving the cleaning effect of dust.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-9, an embodiment of the present invention is: an agricultural product conveying device, including a bottom plate 1, two first vertical plates 2 are fixedly connected to the top of the bottom plate 1, a mesh belt conveyor 3 is arranged between the two first vertical plates 2, and a plurality of mesh plates 4 are arranged inside the mesh belt conveyor 3. The mesh plates 4 are provided to allow air to circulate and facilitate the fall of dust. An anti-accumulation mechanism 5 is arranged inside the mesh belt conveyor 3. The anti-accumulation mechanism 5 includes a fixing plate 511, the fixing plate 511 is fixedly connected to the front surface of the first vertical plate 2, an electric telescopic rod 512 is fixedly connected to the top of the fixing plate 511, a cross plate 513 is fixedly connected to the top of the electric telescopic rod 512, and a plurality of bumps 514 are fixedly connected to the top of the cross plate 513. When the bumps 514 rise, they will contact the mesh belt conveyor 3 to realize the up-and-down shaking of the Chinese herbal medicines on the mesh plates 4, not only cleaning the dust, but also enabling the Chinese herbal medicines to be evenly distributed during the conveying process, avoiding accumulation or blockage, thereby improving the stability and smoothness of the conveying. Support plates 515 are respectively fixedly connected to the tops of the two first vertical plates 2, a sliding rod 516 is fixedly connected between the two support plates 515, four sliding sleeves 517 are movably sleeved on the outer wall of the sliding rod 516, the four sliding sleeves 517 are divided into two groups, and each two sliding sleeves 517 are fixedly connected by a fixing rod. A support rod 518 is hinged between the sliding sleeve 517 and the cross plate 513. One ends of the four sliding sleeves 517 are respectively fixedly connected with a connecting plate 519, an elastic rod 520 is fixedly connected to the bottom of the connecting plate 519, a combing plate 521 is fixedly connected to the bottom of the elastic rod 520, and the bottom of the combing plate 521 is attached to the top of the mesh plate 4. The rise of the support rod 518 will drive the sliding sleeve 517 to move on the sliding rod 516, so that the movement of the sliding sleeve 517 will drive the connecting plate 519 to move, and the movement of the connecting plate 519 will drive the elastic rod 520 to move. The movement of the elastic rod 520 will drive the movement of the combing plate 521, so that the Chinese herbal medicines on the mesh belt conveyor 3 can be evenly turned over, ensuring that the Chinese herbal medicines will not be locally accumulated during the conveying process, and avoiding the conveying blockage or difficult cleaning caused by the accumulation.

[0031] Working principle: Start the electric telescopic rod 512. The electric telescopic rod 512 drives the electric cross plate 513 to rise, thereby driving the convex block 514 to rise through the cross plate 513. When the convex block 514 rises, it will contact the mesh belt conveyor 3, so that the Chinese herbal medicines on the mesh plate 4 can be jolted up and down by the up and down movement of the electric telescopic rod 512, making the Chinese herbal medicines evenly distributed during the conveying process, avoiding accumulation or blockage, thus improving the stability and smoothness of conveying. And when the cross plate 513 rises, it will drive the support rod 518 to rise. The rise of the support rod 518 will drive the sliding sleeve 517 to move on the sliding rod 516. Thus, the movement of the sliding sleeve 517 will drive the connecting plate 519 to move, and the movement of the connecting plate 519 will drive the elastic rod 520 to move. The movement of the elastic rod 520 will drive the movement of the combing plate 521, so that the Chinese herbal medicines on the mesh belt conveyor 3 can be evenly turned over, ensuring that the Chinese herbal medicines will not be locally accumulated during the conveying process, thereby improving the conveying efficiency of the Chinese herbal medicines.

[0032] Please refer to Figures 1-9 On the basis of the above embodiment, in another embodiment of the present invention, a anti-blocking mechanism 6 is provided on the top of the bottom plate 1. The anti-blocking mechanism 6 includes a vertical rod 611. The vertical rod 611 is fixedly connected to the bottom of the cross plate 513. The bottom of the vertical rod 611 is fixedly connected with a first slider 612. A square plate 613 is arranged at the bottom of the first slider 612. A plurality of brushes 614 are fixedly connected to the bottom of the square plate 613. The Chinese herbal medicines blocking the internal mesh holes of the mesh plate 4 can be pushed out and cleaned by the downward movement of the brushes 614. A first sliding groove 615 is formed on the square plate 613. The first slider 612 is slidably connected to the inside of the first sliding groove 615. A first spring 616 is fixedly connected between one side of the first slider 612 and the inner wall of the first sliding groove 615. A first abutting block 617 is fixedly connected to the back of the square plate 613. A second abutting block 618 is fixedly connected to the front of the first vertical plate 2. The first abutting block 617 contacts the second abutting block 618. When the square plate 613 descends to a certain position, the first abutting block 617 will contact the second abutting block 618. Thus, under the action of the second abutting block 618, the first abutting block 617 will be displaced, causing the brushes 614 at the bottom of the square plate 613 to have a slight displacement, improving the cleaning effect on the internal mesh holes of the mesh plate 4, making the mesh holes smoother, facilitating the fall of dust, and thus avoiding the subsequent corruption problem of Chinese herbal medicines caused by dust.

[0033] Working principle: When the cross plate 513 descends, it will drive the vertical rod 611 to descend, and the descent of the vertical rod 611 will drive the square plate 613 at the bottom of the first slider 612 to descend, thereby driving the brush 614 at the bottom of the square plate 613 to descend. Through the descent of the brush 614, the Chinese herbal medicines blocking the internal mesh holes of the mesh plate 4 can be pushed out and cleaned. And when the square plate 613 descends to a certain position, the first contact block 617 will contact the second contact block 618. Thus, under the action of the second contact block 618, the first contact block 617 displaces, causing the brush 614 at the bottom of the square plate 613 to have a slight displacement, improving the cleaning effect on the internal mesh holes of the mesh plate 4, making the mesh holes smoother, facilitating the fall of dust, and thus avoiding the subsequent corruption problem of Chinese herbal medicines caused by dust.

[0034] Please refer to Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, a uniform feeding mechanism 7 is provided on the top of the bottom plate 1. The uniform feeding mechanism 7 includes two second vertical plates 711. A feeding plate 712 is rotatably connected between the two second vertical plates 711. A second chute 713 is opened on the front surface of the first vertical plate 2. A second slider 714 is slidably connected inside the second chute 713. The second slider 714 is rotatably connected to the back of the feeding plate 712. A second spring 715 is fixedly connected between the second slider 714 and the inner wall of the second chute 713. One end of the combing plate 521 is fixedly connected with a contact rod 716. One end of the feeding plate 712 is fixedly connected with a wavy contact plate 717. The contact rod 716 contacts the wavy contact plate 717. When the combing plate 521 moves back and forth, it will drive the contact rod 716 to move back and forth. Under the contact action of the contact rod 716 and the wavy contact plate 717, the wavy contact plate 717 will vibrate slightly up and down, thereby driving the feeding plate 712 to vibrate slightly, ensuring that the agricultural products can be evenly and stably dropped onto the conveyor belt. A third chute 718 is opened on the right side surface of the wavy contact plate 717. A third slider 719 is slidably connected inside the third chute 718. The top of the third slider 719 is fixedly connected with a scraper 720. The scraper 720 is attached to the feeding plate 712. A third spring 721 is fixedly connected between the third slider 719 and the inner wall of the third chute 718. The top of the contact rod 716 is fixedly connected with a push rod 722. The push rod 722 contacts the back of the third slider 719. By the forward and backward movement of the push rod 722, the third slider 719 can be pushed to move forward, thereby driving the scraper 720 to move. The scraper 720 can scrape off some residual Chinese herbal medicines on the feeding plate 712. When the push rod 722 moves backward, the third slider 719 will reset under the elastic action of the third spring 721, thereby realizing the reciprocating scraping of the scraper 720, so as to promote the uniform feeding of Chinese herbal medicines.

[0035] Working principle: When the carding plate 521 moves back and forth, it drives the contact rod 716 to move back and forth. Under the contact action between the contact rod 716 and the wavy contact plate 717, the wavy contact plate 717 makes slight up and down vibrations, thereby driving the blanking plate 712 to vibrate slightly, ensuring that agricultural products can fall onto the conveyor belt evenly and stably. Even blanking avoids the situation of local over-accumulation of traditional Chinese herbs. Moreover, when the contact rod 716 moves back and forth, it drives the push rod 722 to move back and forth. Through the back and forth movement of the push rod 722, the third slider 719 is pushed to move forward, thereby driving the scraper 720 to move. The scraper 720 can scrape off some residual traditional Chinese herbs on the blanking plate 712. When the push rod 722 moves backward, the third slider 719 will reset under the elastic action of the third spring 721, thereby realizing the reciprocating scraping of the scraper 720, so as to promote the even blanking of traditional Chinese herbs.

[0036] The present invention provides an agricultural product conveying device. There are many methods and ways to specifically implement this technical solution. The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be realized by the prior art.
