Description

Technical Field

[0001] The invention relates to the technical field of seed drying, and in particular to agricultural seed drying equipment and a drying method thereof. Background Art

[0002] Agricultural seeds are formed by ovules through pollination and fertilization. Seeds are generally composed of three parts: seed coat, embryo and endosperm. In the cultivation of agricultural seeds, in order to prevent and control diseases and insect pests in the seedling stage and promote seed growth and development, a layer of coating agent needs to be coated on the seeds. After the seeds are coated, they need to be dried. The coated seeds have high moisture content and high viscosity, so they need to be dried using corresponding agricultural seed drying equipment.

[0003] Existing agricultural seed drying equipment can only dry the seeds during the drying process. In fact, the coated seeds tend to stick together into clumps. When dried in the drying equipment, the seeds inside the clumps are often not dried evenly. Subsequent manual screening is required to manually separate the clumped seeds. The high degree of manual participation leads to unsatisfactory drying effects. Summary of the invention

The side wall of the drying tank 101 is provided with a plurality of evenly distributed clamping cavities 206. The inner side wall of the drying tank 101 is provided with an arc-shaped opening connected to the clamping cavities 206. A collecting cover 207 is rotatably sleeved on the rotating rod 202. The top ends of the plurality of discharge pipes 104 are fixedly connected to the collecting cover 207.

[0043] Secondly, the drying separation unit 200 also includes a drying air supply component 201, which includes a heat source box 201a fixedly arranged in the drying tank 101, the lower end of the rotating rod 202 is inserted into the heat source box 201a and is rotatably connected to the heat source box 201a, a driving motor 203 is fixedly installed on the heat source box 201a, and the output shaft of the driving motor 203 is fixedly connected to a driving gear 204, a driven gear ring 205 meshing with the driving gear 204 is fixedly sleeved on the rotating rod 202, and an electric heating network 20 is fixedly arranged in the heat source box 201a. 1d, and the lower side wall of the heat source box 201a is fixedly connected with an air inlet pipe 201c, the lower side wall of the heat source box 201a is fixedly installed with an air pump 201b connected with the air inlet pipe 201c, the lower side wall of the heat source box 201a is fixedly connected with an air blast pipe 201f, the top of the air blast pipe 201f is upwardly inserted into the upper part of the inner cavity of the heat source box 201a, and the top of the air blast pipe 201f is fixedly connected with an air guide cover 201e, and the air guide cover 201e is set in a trumpet shape.

They can form a dense heat-insulating layer in the coating to improve the overall heat-insulating effect of the coating. To avoid heat loss caused by the heat source gas during the transportation through the air blowing pipe 201f and the air blowing branch pipe 201g, a one-way air valve is embedded in the side wall of the drying tank 101. The one-way air valve refers to a valve that allows fluid gas or liquid to pass in one direction and automatically closes in the other direction. Its main working principle is to rely on the force of the medium's own flow to automatically open and close the valve flap, thereby preventing the medium from flowing back. It belongs to a very mature prior art, so the present invention does not make a detailed introduction to its working principle and specific model.

[0044] Furthermore, the drying and separation unit 200 also includes an offset feeding assembly 208, which includes a conical material guide cover 208a fixedly arranged on the upper part of the inner cavity of the drying tank 101, and the rotating rod 202 passes through the conical material guide cover 208a and is rotatably connected to the conical material guide cover 208a, and a plurality of groups of evenly distributed material drop holes 208b are provided at the edge of the conical material guide cover 208a, and a rotating column 208c corresponding to the material drop hole 208b is rotatably connected to the upper end wall of the drying tank 101, and a spiral material guide blade matching the material drop hole 208b is fixedly arranged on the rotating column 208c, and a second transmission wheel 208e is provided on the top fixed sleeve of the rotating column 208c, and a first transmission wheel 208d is provided on the top fixed sleeve of the rotating rod 202, and each second transmission wheel 208e is connected to the first transmission wheel 208d through a corresponding transmission belt.

[0045] Furthermore, the adhesion separation unit 300 includes a separation cover 301 fixedly sleeved on the rotating rod 202 and a bending shaft 307 rotatably connected to the outer wall of the separation cover 301, the separation cover 301 is located between the centrifugal disk 209 and the collecting cover 207, the side wall of the bending shaft 307 is fixedly connected with a plurality of groups of uniformly distributed first rubber branches 308, the inner wall of the drying tank 101 is rotatably connected with a plurality of driven rods 310 corresponding to the bending shaft 307, and the driven rod 310 is fixedly connected with a plurality of groups of uniformly distributed The second rubber branches 311, each first rubber branch 308 has a plurality of uniform first rubber branches 309 fixedly connected to its side wall, and the second rubber branches 311 have a plurality of uniformly distributed second rubber branches 312 fixedly connected to its side wall. In the present invention, the first rubber branches 308, the second rubber branches 311, the first rubber branches 309 and the second rubber branches 312 are all made of fluororubber, which has good high temperature resistance, and the long-term use temperature range is usually 150-200°C.

[0046] Furthermore, a plurality of evenly distributed air ducts 304 are fixedly connected to the lower inner wall of the separation hood 301, each air duct 304 is connected to the corresponding end of the inflation branch, and a plurality of evenly distributed drying nozzles 306 are fixedly connected to the lower end of the air duct 304. A horn drop cover 315 is fixedly provided in the drying tank 101, and the horn drop cover 315 is located between the separation hood 301 and the centrifugal disk 209.

[0047] Furthermore, a conical block 302 is fixedly connected to the side wall of the rotating rod 202, and a plurality of air blowing nozzles 305 corresponding to the position of the upper side wall of the centrifugal disk 209 are provided on the side wall of the conical block 302. An air duct is provided inside the rotating rod 202, and the two ends of the air duct are respectively connected to the air guide pipe 304 and the air blowing nozzle 305; through the use of the conical block 302 and the air duct in conjunction with the air guide pipe 304, part of the gas in the air guide pipe 304 can be recovered and blown out through the air blowing nozzle 305, so as to assist the seeds on the centrifugal disk 209 to quickly enter the clamping cavity 206 for drying and flat throwing, thereby accelerating the drying rate of the seeds by the drying equipment.

Through the arrangement of the first material guide ring 313 and the second material guide ring 314, and the use of multiple rubber branches, the separation effect of the separation cover 301 on sticky seeds is further improved.

[0049] A method for drying agricultural seeds, the drying method is applicable to any of the above drying equipment, and the drying method comprises the following steps:

[0050] S1: Put the seeds to be dried into the upper part of the inner cavity of the drying tank 101, start the drive motor 203, and the spiral guide blades transport the seeds into the drying tank 101;

[0051] S2: The seeds that stick together are separated through the gap between the separation cover 301 and the drying tank 101, and then rolled onto the centrifugal disk 209 through the horn drop cover 315, where they are initially dried. The seeds that fall onto the centrifugal disk 209 enter the clamping chamber 206, and are blown upward by the heat source gas and thrown horizontally through the upper opening of the clamping chamber 206. The seeds that meet the drying requirements and are individually granulated fall into the collecting cover 207 and are discharged through the discharge pipe 104.

[0052] S3: The seeds that are not dried sufficiently or are stuck together are heavy and are separated and dried again through the outside of the separation cover 301. Then the above operation is repeated to complete the drying and separation process of the agricultural seeds.

[0053] During use, the seeds to be dried are put into the upper part of the inner cavity of the drying tank 101, the driving motor 203 is started, the rotating rod 202 drives the multiple rotating columns 208c to rotate, and the spiral guide blades fixedly mounted on the rotating columns 208c transport the seeds into the drying tank 101. When the seeds stuck together pass through the gap between the separation cover 301 and the drying tank 101 under the action of their own gravity, the first rubber branch 308 and the second rubber branch 311 arranged between the outer wall of the separation cover 301 and the inner wall of the drying tank 101 can break up and separate the stuck seeds, and a part of the hot air in the heat source box 201a passes through the air blowing channel 303 and the air blowing branch channel, so that the separation cover 301 forms a temporary "heating ring", and the hot air in the clamping cavity 206 is blown from bottom to top, thereby causing the inner wall of the drying tank 101 and the separation cover 301 to form a temporary "heating ring cavity", so that the stuck seeds are separated and the pre-drying treatment of the seeds is completed;

[0054] Then, in the process of the seeds rolling down through the upper side wall of the trumpet drop cover 315 under the action of their own gravity, the hot air entering the air guide pipe 304 sprays the heat source gas through multiple drying nozzles 306, which can preliminarily dry the seeds passing through the upper surface of the trumpet drop cover 315, and then the seeds roll onto the centrifugal disk 209. The seeds falling on the centrifugal disk 209 are subjected to the centrifugal force and enter the clamping cavity 206, and are blown from bottom to top by the heat source gas and thrown horizontally through the upper end opening of the clamping cavity 206. In this process, the seeds can fully contact with the heat source gas in the clamping cavity 206, so that they are fully dried by the heat source gas. The seeds that meet the drying requirements and are individually granulated are light in weight and have a long horizontal throwing distance, and fall into the collecting hood 207 and are unloaded through the discharge pipe 104.

[0055] Seeds that are not dried sufficiently or are stuck together are heavy and have a short horizontal throwing distance. They are separated and dried again by passing through the outer side of the separation cover 301 and the inner wall of the drying tank 101. Then the above operation is repeated to complete the drying and separation process of the agricultural seeds. This effectively solves the problem of uneven heating of seeds due to seeds sticking together, and the subsequent need for manual screening and rubbing of clumped seeds. This reduces the degree of manual participation in seed drying by the drying equipment and improves the seed drying effect of the drying equipment.

[0056] Embodiment 2

[0057] Reference Fig. 9 , which is different from the first embodiment in that: an air duct 303 connected to the heat source box 201a is fixedly provided at the lower end of the rotating rod 202, and a plurality of air duct branches connected to the air duct 303 are fixedly provided on the side wall of the separation cover 301, and a corresponding axial flow rod 316 is rotatably connected to the lower part of the inner cavity of each air duct, and a plurality of groups of evenly distributed axial flow blades 317 are fixedly sleeved on the axial flow rod 316, and a corresponding second bevel gear 319 is fixedly connected to the bent axial rod 307 inserted into the air duct, and a first bevel gear 318 meshing with the second bevel gear 319 is fixedly sleeved on the axial flow rod 316; after the hot air enters the air duct, it will drive the axial flow rod 316 through the plurality of axial flow blades 317 arranged on the axial flow rod 316 The first bevel gear 318 fixed thereon drives the bending shaft 307 to rotate via the second bevel gear 319. The bending shaft 307 can rotate while following the separation cover 301. In the present invention, the rotation rate of the transfer rod 202 is constant. Even if the bending shaft 307 rotates, it will not collide with the driven rod 310. When the agglomerated seeds pass through the gap between the outer wall of the separation cover 301 and the inner wall of the drying tank 101, they can be fully broken up by the first rubber branch 308 and the second rubber branch 311. Since the first rubber branch 308 and the second rubber branch 311 themselves have a certain elasticity, while ensuring a good breaking effect on the adhered seeds, the surface of the seeds will not be damaged.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
