Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a conveying device for agricultural products with stable transportation. Background Art

[0002] Stable conveying devices are widely used in agricultural production, food processing, pharmaceuticals, construction and road maintenance, and their main function is to accurately control and convey the amount of materials to ensure the continuity and stability of the production process.

[0003] In agricultural production, the stable conveyor is used to accurately control and distribute the amount of agricultural products in each batch, ensuring the uniformity and stability of the conveying, thereby improving production efficiency; the device plays an important role in the conveying of agricultural products, which not only directly affects the subsequent handling and processing, but also affects the efficiency of the entire production process and product quality. In construction and road maintenance, the stable conveyor can be used to evenly distribute building materials such as concrete and sand and gravel to ensure construction quality and structural stability. It can also be used in winter snow removal and anti-skid operations to ensure road safety by evenly distributing anti-skid materials such as sand and salt.

[0004] Common stable conveying devices such as mechanical quantitative conveyors use gear transmission to evenly distribute materials through a rotating feed wheel. Although this gear transmission mechanical structure ensures the accuracy and consistency of the conveying volume, especially when dealing with homogeneous and fluid materials, the effect is more significant. However, since most quantitative conveying devices in the prior art rely on a single type of feed wheel, they lack the ability to efficiently convey smaller particles and can only convey some large particles and coarse materials. During the conveying process, these large particles or irregularly shaped complex materials cannot be processed into a state suitable for conveying, and are easily stuck on the surface of the feed wheel or the discharge outlet, causing material blockage, accumulating at the blockage point to form a blockage belt, making it impossible for subsequent materials to pass smoothly, resulting in uneven conveying, which seriously affects the stability and accuracy of quantitative conveying.

[0005] Therefore, there is an urgent need to improve the feed wheel structure of the stable conveying device so that it can better adapt to the conveying requirements of materials of various particle sizes while delivering quantitatively, ensuring that the material can pass through the conveying device smoothly and evenly, avoiding blockage and uneven conveying problems.

DETAILED DESCRIPTION

[0055] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0056] As attached Figure 1-6 As shown, a stable agricultural product conveying device mainly comprises: a base body 1, a feeding assembly 2 with quantitative feeding and multiple crushing functions, a storage box 3 tiltably arranged on the base body 1, and a discharge trough 4 provided with a coarse grinding wheel 41 and a discharge trough material outlet 42; a plurality of supporting legs are arranged at the bottom of the base body 1; the discharge trough 4 is located at the end of the material storage box 3 in the material flow direction;

[0057] The feeding assembly 2 includes: a feeding chamber 21 having an arc surface 2111, a first feeding wheel 22 and a second feeding wheel 23 arranged in the feeding chamber 21, a meshing conveying space 24, a first gear 25, a second gear 26, a first driving shaft 27, a second driving shaft 28, and a motor 29 connected to the first driving shaft 27;

[0058] The first feeding wheel 22 and the second feeding wheel 23 are arranged transversely at the end of the storage box 3 and mesh with each other to form a meshing conveying space 24;

[0059] The first feeding wheel 22 includes: a first tapered feeding tooth 221, a first concave surface 222 formed between two adjacent first tapered feeding teeth 221, coarsely ground small bevel teeth 223, finely ground large bevel teeth 224 evenly distributed in the first concave surface 222, and auxiliary coarsely ground small teeth 225;

[0060] The first feeding wheel 22 is annularly arranged with a plurality of first tapered feeding teeth 221 in the radial direction;

[0061] The first tapered feed tooth 221 includes: a first closed tooth surface 2211, a first grinding tooth surface 2212, and a first tip 2213;

[0062] A plurality of rough grinding small bevel teeth 223 are evenly distributed on the first grinding tooth surface 2212; a plurality of auxiliary rough grinding small teeth 225 are evenly arranged on the surface of each rough grinding small bevel tooth 223;

[0063] Further, the second feeding wheel 23 includes: a second tapered feeding tooth 231, a second concave surface 232 formed between two adjacent second tapered feeding teeth 231, a primary rebound surface 233, a secondary rebound surface 234, and an auxiliary grinding serrated surface 235;

[0064] The second feeding wheel 23 is annularly arranged with a plurality of second tapered feeding teeth 231 in the radial direction;

[0065] The second tapered feed tooth 231 includes: a second closed tooth surface 2311, a second grinding tooth surface 2312, and a second tip 2313;

[0066] The second grinding tooth surface 2312 is provided with an auxiliary grinding serrated surface 235;

[0067] An inclined secondary rebound surface 234 is provided on one end of the second grinding tooth surface 2312 close to the second tip 2313;

[0068] Furthermore, the secondary rebound surface 234 extends toward the second concave surface 232 to connect with one end of the auxiliary grinding serrated surface 235; the material falling on the secondary rebound surface 234 is rebounded by the secondary rebound surface 234 and guided to the fine grinding large bevel teeth 224 for crushing and grinding.

[0069] The primary rebound surface 233 extends obliquely from the second concave surface 232 toward the second tip 2313 to connect with the other end of the auxiliary grinding serrated surface 235; the material falling on the primary rebound surface 233 is rebounded by the primary rebound surface 233 and guided to the coarse grinding small bevel teeth 223 for crushing and grinding.

[0070] The primary rebound surface 233, the auxiliary grinding serrated surface 235, and the secondary rebound surface 234 form a continuous integral structure; and the three are made of polyurethane composite material in one piece; so that they can effectively rebound materials and provide the hardness required for auxiliary crushing.

[0071] In the centerline direction of the second feeding wheel 23 , the heights of the primary rebound surface 233 , the auxiliary grinding serrated surface 235 , and the secondary rebound surface 234 are the same as the height of the second feeding wheel 23 ;

[0072] Furthermore, the inclination direction of the primary rebound surface 233 is consistent with the inclination direction of the secondary rebound surface 234;

[0073] The value range of the angle a between the primary rebound surface 233 and the second grinding tooth surface 2312 is 35° to 50°, so that the primary rebound surface 233 can rebound the material onto the coarse grinding small bevel tooth 223;

[0074] The value range of the angle b between the secondary rebound surface 234 and the second grinding tooth surface 2312 is 20° to 30°, so that the secondary rebound surface 234 can rebound the material onto the fine grinding large bevel tooth 224.

[0075] As attached Figure 3 As shown, the material falls down to the primary rebound surface 233 and the auxiliary grinding serrated surface 235 under the action of gravity: the auxiliary grinding serrated surface 235 breaks some large particles or agglomerated materials in contact with it; and the material in contact with the primary rebound surface 233 is rebounded and impacted on the coarse grinding small bevel teeth 223 and the auxiliary coarse grinding small teeth 225 to be broken into smaller particles. Compared with the single coarse grinding small bevel teeth 223, the auxiliary coarse grinding small teeth 225 can increase the grinding surface area of ​​the coarse grinding small bevel teeth 223, further assist and enhance the initial crushing function of the coarse grinding small bevel teeth 223, and can further refine and crush some small and medium particles impacting on it, making the material finer and more uniform, which helps to prevent the problem of material blockage during the transportation process, thereby improving the continuity and stability of the system.

[0076] The materials crushed by the coarse grinding small bevel teeth 223 and the auxiliary coarse grinding small teeth 225 arranged on the surface fall down again to the auxiliary grinding sawtooth surface 235 and the secondary rebound surface 234 under the action of gravity: the materials in contact with the secondary rebound surface 234 will be rebounded by the secondary rebound surface 234 and impacted on the fine grinding large bevel teeth 224, and the large particles of materials that are not completely crushed will be crushed and ground again. The small and medium particles of materials that are not completely crushed and fall on the auxiliary grinding sawtooth surface 235 will be further ground and refined by the auxiliary grinding sawtooth surface 235. The materials are continuously crushed during the transmission process, thereby ensuring the degree of material refinement and further reducing the possibility of material blockage.

[0077] Furthermore, the first tapered feed tooth 221 is oriented toward the center of the first feed wheel 22, and the width of its cross section gradually increases;

[0078] The second tapered feeding tooth 231 is oriented toward the center of the second feeding wheel 23, and the width of its cross section gradually increases;

[0079] That is, the root of the first tapered feed tooth 221 is thicker than the tooth tip; the root of the second tapered feed tooth 231 is thicker than the tooth tip;

[0080] The outermost edge of the first tapered feed tooth 221 is formed with a first tip 2213;

[0081] A second tip 2313 is formed at the outermost edge of the second tapered feed tooth 231 .

[0082] As attached Figure 2 As shown, the material first contacts the first tip 2213 and the second tip 2313, and then gradually transitions to the thicker part of the tooth root along the first tapered feeding tooth 221; compared with the teeth on conventional gears, the first tip 2213 and the second tip 2313 of the present application have a smaller contact surface area, which reduces the possibility of material adhering to the first tip 2213 and the second tip 2313, and reduces the risk of blockage caused by adhesion and accumulation of materials during transportation; at the same time, the first tip 2213 and the second tip 2313 have a smaller contact area. Under the action of the same force, the first tip 2213 and the second tip 2313 can concentrate on applying greater contact pressure to the materials in contact with them, thereby assisting in crushing some harder or complex materials and reducing the crushing burden of subsequent materials in the meshing conveying space 24.

[0083] Furthermore, the first tapered feed tooth 221 has two tooth surfaces, wherein the side opposite to the rotation direction of the first feed wheel 22 is a first closed tooth surface 2211; and the side in the same rotation direction as the first feed wheel 22 is a first grinding tooth surface 2212;

[0084] The second tapered feed tooth 231 also has two tooth surfaces, wherein the side opposite to the rotation direction of the second feed wheel 23 is a second grinding tooth surface 2312 ; and the side in the same rotation direction as the second feed wheel 23 is a second closed tooth surface 2311 .

[0085] Furthermore, two adjacent auxiliary rough grinding teeth 225 are arranged to have a certain gap to reduce the accumulation and clogging of materials between the teeth;

[0086] The length of the finely ground large bevel teeth 224 is greater than the length of the coarsely ground small bevel teeth 223; that is, the finely ground large bevel teeth 224 are sharper than the coarsely ground small bevel teeth 223;

[0087] Furthermore, the coarse grinding small bevel teeth 223, the fine grinding large bevel teeth 224, and the auxiliary coarse grinding small teeth 225 are made of wear-resistant materials with a certain hardness; to ensure that the tooth tips are persistently sharp and wear-resistant during the fine grinding process; such as: tungsten carbide composite materials, high chromium cast iron.

[0088] Furthermore, the distribution form and quantity of the coarse grinding small bevel teeth 223, the fine grinding large bevel teeth 224, and the auxiliary coarse grinding small teeth 225 should be arranged according to actual application requirements.

[0089] Furthermore, the meshing conveying space 24 is formed by the first tapered feed tooth 221 and the second tapered feed tooth 231 abutting against each other and closing; specifically, the first closed tooth surface 2211 of the first tapered feed tooth 221 abuts against the second closed tooth surface 2311 of the second tapered feed tooth 231.

[0090] The first feeding wheel 22 and the second feeding wheel 23 have the same size and rotation speed. The contact point positions and spacings of the first tapered feeding teeth 221 and the second tapered feeding teeth 231 are kept consistent, thereby ensuring that the meshing conveying space 24 formed has the same shape and size. Therefore, the amount of material captured and accommodated by the meshing conveying space 24 is constant, thereby achieving accurate quantitative conveying of materials.

[0091] Further, the feeding chamber 21 includes: a feeding chamber housing 211, a material inlet 212 located above the first feeding wheel 22 and the second feeding wheel 23, and a material discharge port 213 located below the first feeding wheel 22 and the second feeding wheel 23;

[0092] The feeding chamber shell 211 is a box body with open structures at both ends, and the middle part of its two side surfaces is an arc-shaped surface 2111 protruding outward; the shape of the arc-shaped surface 2111 is adapted to the first feeding wheel 22, and the first feeding wheel 22 fits the inner wall surface of the arc-shaped surface 2111; this arrangement helps to prevent the material from flowing back from the bottom to the top during the conveying process, so that the material can stably fall down from the material inlet 212 and be conveyed to the material outlet 213 through the first feeding wheel 22 and the second feeding wheel 23, thereby ensuring that the material is effectively conveyed along the above path; at the same time, the setting of the shape of the arc-shaped surface 2111 further provides additional mechanical support for the first feeding wheel 22 and the second feeding wheel 23, reduces the swing or deviation of the first feeding wheel 22 and the second feeding wheel 23 during operation, and thereby extends their service life.

[0093] Furthermore, two identical rough grinding wheels 41 are arranged inside the discharge chute 4; the two rough grinding wheels 41 are located on the same horizontal plane and are parallel to the transverse direction of the end of the storage box 3;

[0094] The bottom of the discharge trough 4 is provided with a discharge trough material outlet 42; the cross section of the discharge trough material outlet 42 is a truncated cone shape with a wide top and a narrow bottom, a hollow structure;

[0095] The lower end of the discharge chute 4 is connected and fixed to the upper end of the feeding chamber shell 211 , so that the material outlet 42 of the discharge chute is located above the meshing point of the first feeding wheel 22 and the second feeding wheel 23 , and inside the material inlet 212 .

[0096] After the material is initially ground by two coarse grinding wheels 41 in the discharge chute 4 , it is transported to the feeding assembly 2 through the material outlet 42 of the discharge chute.

[0097] The shape and structure of the material outlet 42 of the discharge chute enables the material to flow downward smoothly under the action of gravity and reach the first feeding wheel 22 and the second feeding wheel 23;

[0098] The materials dropped onto the first feeding wheel 22 and the second feeding wheel 23 are immediately caught by the first tapered feeding teeth 221 and the second tapered feeding teeth 231 and transferred to the meshing conveying space 24 for crushing and grinding, since the first feeding wheel 22 and the second feeding wheel 23 rotate in opposite directions. This can effectively reduce the deviation and dispersion of materials during the conveying process, prevent the backflow or rebound of materials, and thus improve the stability and continuity of the conveying.

[0099] Furthermore, the first gear 25 is connected and fixed to the surface of the first feeding wheel 22 facing the storage box 3; and the first gear 25 and the first feeding wheel 22 are sleeved on the first driving shaft 27;

[0100] The first driving shaft 27 passes through the surface of the feeding chamber housing 211 toward the storage box 3 and is connected to a motor 29;

[0101] The second gear 26 is connected and fixed to a surface of the second feeding wheel 23 on one side facing the storage box 3; the second gear 26 and the second feeding wheel 23 are sleeved on the second driving shaft 28;

[0102] Further, the first gear 25 and the second gear 26 have the same structure, and the two are configured to enable the first feeding wheel 22 and the second feeding wheel 23 to mesh with each other and form a working state with a meshing conveying space 24, so as to achieve synchronous rotation of the first feeding wheel 22 and the second feeding wheel 23 in opposite rotation directions;

[0103] The diameter, number of teeth, center distance, module and other factors of the first gear 25 and the second gear 26 should be determined according to the size of the first feeding wheel 22 and the second feeding wheel 23 and the required transmission ratio; the first gear 25 and the second gear 26 are prior art and are not the focus of this application, so they will not be described in detail.

[0104] Furthermore, the motor 29 and the feeding assembly 2 are further fixed to the base body 1 by providing a supporting component, so as to ensure the stability and vibration reduction effect of the motor 29 and the feeding assembly 2 during the working process.

[0105] The storage box 3 can adjust the tilt angle of the storage box 3 according to the needs by installing a tiltable mechanism; these devices allow the operator to accurately control the position and angle of the storage box to adapt to different working scenes and requirements, ensuring that the materials can flow smoothly and be output quantitatively. The above is a common technical means in modern engineering design and manufacturing, and is widely used in various industrial and agricultural equipment. It belongs to the prior art, so it will not be described in detail. Please refer to CN113440161A and CN114869655A.

[0106] Specific working method: start the motor 29 of the feeding assembly 2, drive the first gear 25 to rotate counterclockwise through the first driving shaft 27, and the first gear 25 drives the second gear 26 to rotate clockwise; the movement of the first gear 25 and the second gear 26 causes the first feeding wheel 22 and the second feeding wheel 23 to rotate synchronously in opposite directions.

[0107] Adjust the storage box 3 to the desired inclination angle. Under the action of gravity, the material in the storage box 3 flows into the discharge chute 4 and reaches the two coarse grinding wheels 41. After preliminary processing by the coarse grinding wheel 41, the material enters the first feeding wheel 22 and the second feeding wheel 23 in the feeding chamber 21 through the material outlet 42 of the discharge chute.

[0108] The material first contacts the first tip 2213 and the second tip 2313, and then transitions to the thicker part of the tooth root along the first tapered feed tooth 221. The first feed wheel 22 rotates counterclockwise and the second feed wheel 23 rotates clockwise, so that the material falling on the first tapered feed tooth 221 and the second tapered feed tooth 231 is directly grabbed by the first tapered feed tooth 221 and the second tapered feed tooth 231; as they rotate, the first tapered feed tooth 221 and the second tapered feed tooth 231 gradually mesh, sealing the material in the meshing conveying space 24.

[0109] The material falls downwards to the primary rebound surface 233 and the auxiliary grinding serrated surface 235 under the action of gravity: the auxiliary grinding serrated surface 235 applies uniform pressure to the material in contact with it, and performs primary crushing and grinding on some small and medium-sized particles; the primary rebound surface 233 rebounds the material in contact with it to the coarse grinding small bevel teeth 223 and the auxiliary coarse grinding small teeth 225, the coarse grinding small bevel teeth 223 perform primary crushing and grinding on some larger particles, and the auxiliary coarse grinding small teeth 225 simultaneously perform primary crushing and grinding on small and medium-sized particles.

[0110] After the first crushing and grinding, the material falls down again onto the auxiliary grinding serrated surface 235 and the secondary rebound surface 234 under the action of gravity: the material in contact with the secondary rebound surface 234 is rebounded to the fine grinding large bevel teeth 224 for secondary crushing and grinding, so that the large particles that are not completely crushed are further refined; the other part falls onto the auxiliary grinding serrated surface 235 again for secondary crushing; finally, the material that has been crushed and ground for multiple times is evenly discharged from the material discharge port 213.

[0111] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
