Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically to a particle size monitoring instrument for sunflower seeds used in agricultural production. Background Technology

[0002] A sunflower seed particle size monitoring instrument is a device used to distinguish the particle size of sunflower seeds. In the processing of agricultural products such as sunflower seeds, the distinction between particle size and the separation of impurities are important links that affect product quality. Sunflower seeds of different particle sizes need to be used for different sales scenarios. Smaller particle size sunflower seeds are often used for packaging as snacks, while larger particle size sunflower seeds are often used for gift boxes. In addition, the raw materials of sunflower seeds often contain impurities such as small particle size dust and broken shells, as well as impurities such as large particle size stones and immature shells. Therefore, the ability to screen sunflower seeds from impurities and sunflower seeds of different particle sizes is an important requirement for sunflower seed processing.

[0003] Currently, existing sunflower seed particle size monitoring instruments require multiple devices to be connected in series to screen sunflower seeds from impurities and sunflower seeds of different particle sizes. This not only occupies a large area but also requires additional material conveying devices, making it unsuitable for small- to medium-scale processing scenarios. Therefore, a sunflower seed particle size monitoring instrument with high integration and small footprint is needed. Utility Model Content

[0004] The purpose of this invention is to provide a seed particle size monitoring instrument for agricultural production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sunflower seed particle size monitoring instrument for agricultural production, comprising a support shaft fixed on a base, a cone with a large end opening slidably disposed on the support shaft, a sunflower seed inlet fixed at the small end of the cone, a front screen and a rear screen arranged sequentially from the small end to the large end below the cone, a front collection component disposed below the cone, and the front collection component fixed on the base. The large end of the cone extends into the cylinder fixed on the base. A sieving frame is rotatably installed inside the cylinder. Multiple blades are fixed on the sieving frame. The blades can push the sunflower seeds upward. A lower screen and an upper screen are arranged in order from low to high on the lower side of the cylinder. The aperture of the screens increases in the order of front screen, rear screen, lower screen and upper screen. A rear collection component is installed at the bottom of the cylinder and is fixed on the base. An internal gear ring is fixed on the screening frame. A vibrating gear that meshes with the internal gear ring is installed inside the cylinder.

Detailed Implementation

[0018] 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.

[0019] This utility model provides a technical solution: a particle size monitoring instrument for sunflower seeds used in agricultural production, such as... Figure 1 , 2 As shown, in order to facilitate the differentiation of sunflower seeds of different sizes, a support shaft 102 is included. The support shaft 102 is fixed on the base 101. A cone 103 is slidably arranged on the support shaft 102. The cone 103 has an opening at its large end and a sunflower seed inlet 104 fixed at its small end. A front screen 113 and a rear screen 114 are arranged sequentially from the small end to the large end below the cone 103. The aperture of the front screen 113 is smaller than that of the rear screen 114. A front collection component 106 is arranged below the cone 103 and is fixed on the base 101.

[0020] During operation, sunflower seeds enter the cone 103 through the sunflower seed inlet 104. Under their own gravity, they slide along the inclined inner wall of the cone 103 towards the larger end. During the sliding process, they pass through the front screen 113 and the rear screen 114. When passing through the front screen 113, smaller impurities fall from the front screen 113 into the front collection component 106. When passing through the rear screen 114, smaller sunflower seeds fall from the rear screen 114 into the front collection component 106, thus separating the smaller impurities from the smaller sunflower seeds.

[0021] like Figure 2-4 As shown, the large end of the cone 103 extends into the cylinder 200, which is fixed to the base 101. A sieve frame 201 is rotatably installed inside the cylinder 200, and multiple blades 204 are fixed on the sieve frame 201. When the blades 204 rotate, their working surfaces contact the sunflower seeds, using friction and thrust to lift the sunflower seeds from the bottom of the cylinder 200. A lower screen 209 and an upper screen 210 are arranged in order from low to high on the lower side of the cylinder 200. The aperture of the screens increases in the order of the front screen 113, the rear screen 114, the lower screen 209, and the upper screen 210. A rear collection component 215 is installed below the cylinder 200 and is fixed to the base 101. When the sunflower seeds lifted by the blades 204 pass through the lower screen 209 and the upper screen 210, they pass through the screens under their own gravity and fall into the rear collection component 215.

[0022] When the sunflower seeds fall from the large end of the cone 103 into the cylinder 200, the screening frame 201 rotates, which in turn drives the blades 204 to rotate, causing the blades 204 to push the sunflower seeds upward. During the upward movement, the seeds pass through the lower screen 209 and the upper screen 210. When passing through the lower screen 209, the larger sunflower seeds fall from the lower screen 209 into the rear collection component 215. When passing through the upper screen 210, the larger impurities (the larger impurities are larger than the larger sunflower seeds) fall from the upper screen 210 into the rear collection component 215, thus separating the larger impurities from the larger sunflower seeds.

[0023] like Figure 1 , 4 As shown, in order to improve the screening efficiency of the cone 103, an internal gear ring 205 is fixed on the screening frame 201, and a vibrating gear 206 that meshes with the internal gear ring 205 is rotatably arranged inside the cylinder 200. One end of the connecting rod 207 is hinged to the vibrating gear 206, and the other end of the connecting rod 207 is hinged to the slider 208. The slider 208 is installed inside the cone 103 and is slidably installed on the support shaft 102.

[0024] The rotation of the screening frame 201 can drive the internal gear ring 205 to rotate, which in turn drives the vibrating gear 206 to rotate, which in turn drives the connecting rod 207 to move, which in turn drives the slider 208 to move along the support shaft 102, which in turn drives the cone 103 to slide along the support shaft 102, which in turn causes the cone 103 to vibrate, preventing sunflower seeds from being stuck in the cone 103, and ensuring that the sunflower seeds are in full contact with the front screen 113 and the rear screen 114, reducing the phenomenon of screen leakage and screen blockage, and improving screening efficiency.

[0025] In summary, the cone 103 separates smaller impurities and smaller sunflower seeds, while the cylinder 200 separates larger impurities and larger sunflower seeds. This integrates the screening of sunflower seeds, impurities, and sunflower seeds of different sizes into a single device, avoiding the need for additional conveying devices and reducing the overall footprint. It is suitable for small to medium-scale sunflower seed processing. When the screening frame 201 rotates, it can push the sunflower seeds in the cylinder 200 upward through the blades 204, allowing the seeds to pass through the lower screen 209 and the upper screen 210. It can also drive the internal gear ring 205 to rotate, which drives the connecting rod 207 to move through the meshing vibrating gear 206, thereby moving the slider 208 on the cone 103, causing the cone 103 to vibrate and improving screening efficiency.

[0026] like Figure 1 As shown, for easy feeding, the seed inlet 104 is connected to the funnel 105 via a flexible hose, and the funnel 105 is fixed on the base 101.

[0027] like Figure 2 , 4 As shown, the specific connection structure between the cone cylinder 103 and the support shaft 102 is as follows: the small end of the cone cylinder 103 is fixed with a front sliding sleeve 115, and the large end of the cone cylinder 103 is fixed with a rear sliding sleeve 116 through spokes 117. A slider 208 is fixed on the rear sliding sleeve 116, and both the front sliding sleeve 115 and the rear sliding sleeve 116 are slidably mounted on the support shaft 102.

[0028] like Figure 2 As shown, in order to improve the stability of the cone 103 when sliding, an ear plate 107 is fixed to the outside of the cone 103. The ear plate 107 is slidably set on the track 108, and the track 108 is fixedly installed on the base 101.

[0029] like Figure 2 The specific structure of the front collection component 106 is as follows: the front collection component 106 includes two collection troughs 109. A collection trough 109 is respectively provided under the front screen 113 and the rear screen 114, which are used to collect impurities with smaller particle size and sunflower seeds with smaller particle size, respectively.

[0030] like Figure 4As shown, the specific structure of the screening frame 201 is as follows: the screening frame 201 includes a front support 202 and a rear support 203. The front support 202 and the rear support 203 are respectively fixed at both ends of the blade 204. The front support 202 is rotatably set at the front opening of the cylinder 200, and the rear support 203 is rotatably set at the rear end face of the cylinder 200. An internal gear ring 205 is coaxially fixed on the rear support 203.

[0031] like Figure 2 As shown, the specific driving method of the screening frame 201 is as follows: an external gear ring 111 is coaxially fixed on the front support 202, the external gear ring 111 is meshed with a drive gear 112, the drive gear 112 is fixed on the output shaft of the drive motor 110, and the drive motor 110 is fixed on the cylinder 200.

[0032] The drive motor 110 can drive the drive gear 112 to rotate, which in turn drives the outer gear ring 111 to rotate, which in turn drives the front bracket 202 to rotate, which in turn drives the blade 204 to rotate, which in turn drives the rear bracket 203 to rotate, which in turn drives the inner gear ring 205 to rotate.

[0033] like Figure 4 As shown, the specific structure of the rear collection component 215 is as follows: the rear collection component 215 includes two collection troughs 109. A collection trough 109 is respectively provided under the lower screen 209 and the upper screen 210, which are used to collect sunflower seeds with larger particle size and impurities with larger particle size, respectively.

[0034] like Figure 5 As shown, the specific hinged connection between the vibrating gear 206 and the connecting rod 207 is as follows: a cross shaft 211 is hinged to the vibrating gear 206, and a connecting rod 207 is hinged to the cross shaft 211 via a U-shaped frame 216. In this embodiment, the vibrating gear 206 is hinged to the vertical branch of the cross shaft 211, and the connecting rod 207 is hinged to the horizontal branch of the cross shaft 211.

[0035] like Figure 6 As shown, the specific hinge connection between slider 208 and connecting rod 207 is as follows: slider 208 includes inner sleeve 212, which is sleeved on support shaft 102 and fixed on rear sliding sleeve 116. Outer sleeve 213 is rotatably provided on inner sleeve 212, and trunnion 214 is fixed on outer sleeve 213. Connecting rod 207 is hinged to trunnion 214 through U-shaped frame 216.

[0036] Working process: During operation, sunflower seeds enter the cone 103 through the sunflower seed inlet 104. Under their own gravity, they slide along the inclined inner wall of the cone 103 towards the larger end. During the sliding process, they pass through the front screen 113 and the rear screen 114. When passing through the front screen 113, smaller impurities fall from the front screen 113 into the front collection component 106. When passing through the rear screen 114, smaller sunflower seeds fall from the rear screen 114 into the front collection component 106, thus separating the smaller impurities and smaller sunflower seeds.

[0037] When sunflower seeds fall from the large end of the cone 103 into the cylinder 200, the screening frame 201 rotates, which in turn drives the blades 204 to rotate, causing the blades 204 to push the sunflower seeds upward. During the ascent, the seeds pass through the lower screen 209 and the upper screen 210. When passing through the lower screen 209, larger sunflower seeds fall from the lower screen 209 into the rear collection component 215. When passing through the upper screen 210, larger impurities fall from the upper screen 210 into the rear collection component 215. This separates the larger impurities from the larger sunflower seeds. The sunflower seed particle size is monitored through the cooperation of the cone 103 and the cylinder 200.

[0038] The rotation of the screening frame 201 can drive the internal gear ring 205 to rotate, which in turn drives the vibrating gear 206 to rotate, which in turn drives the connecting rod 207 to move, which in turn drives the slider 208 to move along the support shaft 102, which in turn drives the cone 103 to move, which in turn causes the cone 103 to vibrate, thus preventing the sunflower seeds from being stuck in the cone 103, and ensuring that the sunflower seeds are in full contact with the front screen 113 and the rear screen 114, reducing the phenomenon of screen leakage and screen blockage, and improving screening efficiency.

[0039] Staff members classify and weigh sunflower seeds of different sizes in different collection tanks 109 to monitor and statistically analyze the distribution of sunflower seed size.
