Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a potato screening machine that is easy to clean and screen. Background Technology

[0002] In modern agricultural production, potatoes are one of the main food crops, and their post-processing is of great significance for improving production efficiency and product quality. Traditional potato processing methods rely on manual operation or simple mechanical assistance, which are not only labor-intensive but also inefficient and ineffective in meeting the demands of modern agriculture.

[0003] In existing potato screening technologies, some devices attempt to screen potatoes through mechanical vibration or a single screening mesh. However, these devices often cannot simultaneously perform washing and screening, requiring additional washing steps after initial screening and increasing the complexity of the process. Furthermore, single-function screening equipment has limitations in processing efficiency and accuracy, making it difficult to meet the refined sorting needs of potatoes of different sizes.

[0004] However, existing potato screening machines designed for easy cleaning and screening have some design flaws, such as low screening efficiency, unsatisfactory cleaning results, and complex operation. These problems limit the widespread application of such machines. For example, some machines cannot effectively remove dirt from the surface of potatoes during the cleaning process, leading to difficulties in subsequent processing. Utility Model Content

[0005] The purpose of this invention is to propose a potato screening machine that is easy to clean and screen, so as to solve the problems of low potato screening efficiency and unsatisfactory cleaning effect in the existing technology.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A potato screening machine that facilitates cleaning and screening includes a support frame, a screen, a washing mechanism, and a blower.

The washing mechanism is installed inside the screen to clean potatoes with soil. The blower is installed on one side of the screen on the support frame, and multiple discharge bins are arranged at the bottom of the screen on the support frame, from which the screened potatoes are discharged.

[0008] By adopting the above technical solutions, potatoes can be effectively cleaned and screened, improving the automation level of the operation, reducing manual operation, and enhancing screening efficiency and cleaning effect.

[0009] Furthermore, the screen is divided into a washing section and a screening section. The washing section has a larger mesh size, and the screening section is divided into multiple screening zones. The screening section is uniformly provided with through holes, and the diameter of the through holes gradually increases from the end closer to the washing section to the end farther away.

[0010] By adopting the above technical solution, it is possible to achieve fine screening of potatoes, separating potatoes of different sizes through through holes of different diameters, thereby improving the accuracy of screening.

[0011] Furthermore, the support is provided with a circular roller that drives the screen to rotate, and a support beam extending towards the center is provided on the screen, the support beam being fixedly installed on the circular roller.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] This embodiment relates to a potato screening machine that is easy to clean and screen. In terms of overall structure, as follows... Figure 1 As shown, it includes a support 1, a screen 2, a cleaning mechanism 3, and a fan 4.

[0043] The screen 2 is rotatably mounted on the support 1. Potatoes of different sizes are screened as they pass through the screen 2. The washing mechanism 3 is installed inside the screen 2 to wash the potatoes with soil. The blower 4 is installed on one side of the screen 2 on the support 1 to dry the washed potatoes. Multiple discharge bins 5 are arranged at the bottom of the screen 2 on the support 1. The screened potatoes are discharged from different discharge bins 5.

[0044] It is worth mentioning that the screen 2 is arranged horizontally on the support 1 and connected to the support 1 through bearings. Since potatoes are of different sizes and mixed together after harvest, the screen 2 can separate potatoes of different sizes and collect potatoes of the same size together for sale. The washing mechanism 3 is located at one end of the feed inlet of the screen 2 to ensure that the potatoes are washed before entering the screen 2, making it easier to identify the size of the potatoes and increasing their appearance. The fan 4 is located on one side of the screen 2 and can blow airflow on the screen 2 and the discharge bin 5 to speed up the drying of the potato skin and prevent rotting. Multiple discharge bins 5 are arranged along the axis of the screen 2 to ensure that potatoes falling from different positions can enter different discharge bins 5, thereby achieving screening.

[0045] Based on the above overall introduction, this embodiment presents an exemplary structure of a potato screening machine that facilitates cleaning and screening, such as... Figure 2 As shown, the screen 2 is divided into a washing section 201 and a screening section. The washing section 201 has a larger mesh size and discharges sludge. The screening section is divided into multiple screening zones 202. Through holes 203 are evenly opened on the screening section. The diameter of the through holes 203 gradually increases from the end closer to the washing section 201 to the end farther away.

[0046] Specifically, the washing section 201 has a larger mesh size and smaller sieve holes to ensure that potatoes do not leak out of the washing section 201. Instead, the washing water and dirt will flow out of the washing section 201 and enter the discharge hopper 5 at the bottom of the washing section 201, and then be discharged. The setting of multiple screening zones 202 ensures that potatoes of various sizes can be screened out. The larger the diameter, the larger the potato screened out. Each screening zone 202 has a discharge hopper 5 at the bottom to ensure that the screened potatoes can be collected. Depending on the situation, the diameter of the through hole 203 of each screening zone 202 can be selected as six centimeters, eight centimeters, ten centimeters, etc., and can be set according to the needs.

[0047] As a preferred option, such as Figure 3As shown in this embodiment, a circular roller 204 that drives the screen 2 to rotate is provided on the support 1, and a support beam 205 extending towards the center is provided on the screen 2. The support beam 205 is fixedly installed on the circular roller 204. Specifically, both ends of the circular roller 204 are mounted on the support 1 through bearings, and multiple support beams 205 are provided on the inner circumference of the screen 2, respectively installed on the circular roller 204. That is to say, the circular roller 204 is located at the axis of the screen 2, which facilitates the rotation of the screen 2 and does not affect the rolling of the potatoes inside the screen 2.

[0048] In addition, in this embodiment, a connecting ring 206 is provided between adjacent screening zones 202. One end of the support beam 205 is installed on the inner wall of the connecting ring 206, and the other end is provided with a sleeve 207. A bolt 208 is passed through one side of the sleeve 207, and the bolt 208 abuts against the circular roller 204. Specifically, the connecting ring 206 is used to connect the washing section 201 and multiple screening zones 202. Support rings 209 are provided on both sides of the connecting ring 206 for the washing section 201 and screening zone 202 to be inserted, which facilitates the assembly of the screen 2. The sleeve 207 is inserted into the circular roller 204, and the sleeve 207 is fixed to the circular roller 204 by rotating the bolt 208. Both ends of the screening section are fixed to the circular roller 204 by the connecting ring 206, and one end of the washing section 201 is inserted into the support ring 209, thereby realizing the assembly of the screen 2.

[0049] As a preferred option, such as Figure 1 and Figure 4 As shown, in this embodiment, a feed plate 6 for potatoes is installed at one end of the screen 2, and a discharge plate 7 is installed at the other end. A first motor 8 that drives the screen 2 to rotate is fixedly installed on the support 1. A sprocket 9 is installed on the first motor 8 and the screen 2, respectively, and the two sprockets 9 are connected by a chain. Specifically, the feed plate 6 and the discharge plate 7 are installed at both ends of the discharge bin 5, or at both ends of the support 1, to ensure that potatoes can enter the screen 2 from the feed plate 6 and exit the screen 2 from the discharge plate 7. The purpose of setting the discharge plate 7 is to allow potatoes that are too large to be screened out in the screening area 202 to be discharged from the discharge plate 7. The sprocket 9 on the screen 2 is installed on the roller 204. When the first motor 8 is started, it drives the two pulleys and the chain drive, thereby driving the roller 204 to rotate.

[0050] As a preferred implementation method, such as Figure 5As shown, the cleaning mechanism 3 in this embodiment includes a water pipe 301 fixedly mounted on the support 1. The water pipe 301 extends into the screen 2 from one end, and nozzles 302 are arranged on the water pipe 301. It should be noted that the water pipe 301 is fixedly mounted on the support 1 and located on one side of the roller 204. One end of the cleaning section 201 can be fixed to the connecting ring 206 with screws, and the other end can be left unsupported. Of course, in order to ensure the strength of the cleaning section 201, an auxiliary wheel 11 can be rotatably mounted on the support 1. The auxiliary wheel 11 abuts against the other end of the cleaning section 201 to ensure that the water pipe 301 can extend into the cleaning section 201.

[0051] As a preferred option, such as Figure 6 As shown, in this embodiment, a second motor 10 is provided on one side of the blower 4, and the air outlet of the blower 4 faces the screen 2 and the discharge bin 5. One end of the support 1 protrudes upward. Specifically, the blower 4 is installed on one side of the support 1, mainly located in the screening section, to dry the potatoes in the screening section, ensuring that the surface of the screened potatoes is dry. One end of the roller 204 is installed on the protruding end of the support 1. This arrangement ensures that the screen 2 is in an inclined state, preventing the potatoes from rotating in the same area of ​​the screen 2.

[0052] The potato screening machine in this embodiment, which is easy to clean and screen, improves the efficiency and effectiveness of potato processing by integrating cleaning and screening functions. The design of the screen 2 allows for the effective separation of potatoes of different sizes, improving the screening accuracy. The structure of the roller 204 and the support beam 205 enhances the stability and strength of the screen 2, ensuring the continuity of the screening process. The combined use of the motor and sprocket 9 simplifies the operation process and improves the automation level of the equipment.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
