Creation Instructions (1) · [Technical Field to which the New Type belongs]-This creation is an improvement of the structure of the sifting screen, especially the radial mesh in the curved frame is provided with a plurality of corresponding centers in a radial direction. The long through-holes are used to fix and fix the longitudinal net rods with long elliptical cross-sections. The axial net rods can improve the pressure-bearing property and continue the abrasion resistance, and can form better linear contact with the ears of rice. [Prior technology] The dehydration machine is mainly provided with a dehydration screen on the periphery of the dehydration cylinder and maintains a distance. The rotation of the dehydration cylinder actively and continuously beats the ears of rice, and then the ears are removed from the lower (periphery). The grain sieve forms an impedance, which promotes the smooth separation of the rice stalk from the rice stalk and falls. It can be seen that in the structure setting of the dehydration machine, the dehydration screen® is very important and must withstand the pressure of the rice ear and continuous friction. In the design of the conventional sifting screen, the meshes made by staggered welding of radial and axial round rods are simply arranged in the arc frame (as shown in the first figure), and several meshes are arranged on the mesh. For the reinforcement ribs, the mesh is combined with the decoupling cylinder to perform the decoupling action. However, because the setting of the reinforcement ribs can only provide better pressure resistance at this position, the mesh part that is farther away from the reinforcement ribs will support The lower the compressibility (the elastic deformation caused by the downward depression when bearing the pressure of the ear of rice, reducing the dehydration efficiency), and because the welded mesh is very thin, it often breaks due to severe wear after a period of use Or, because the welding point is not stable or is continuously slammed by the ears of rice, it causes the problem that the entire dehydration screen must be replaced. In view of the above-mentioned problems of usage, the creator feels that the cost of manufacturing the conventional sieve is high, but the use time has not been effectively improved, and

Creation instructions (2) Loss of maintenance costs, so with its many years of professional manufacturing experience in creative design, actively research and development and improvement, under the careful consideration of various conditions, finally created the composition of this structure , Will completely solve the lack of practice. [New content] This creation is an improvement of the structure of the sifting screen, especially the radial mesh in the arc frame is provided with a plurality of long through holes corresponding to the center and radiating in the radial direction, so as to provide a long elliptical cross-section axis It is inserted and fixed to the net rod, so it has the following benefits after implementation: 1. Since the sifting screen created by this creation is an axial net rod with a long elliptical cross section inserted into the radial net bar, so the axial direction The net rod can have better pressure-bearing properties. 2. The axial net rod of this creation is set in a radial state relative to the center, so it can form a better linear contact with the ear of rice to make the rice paddy fall smoothly. The long oval section of the net rod prolongs the wear resistance and improves the service time. 3. Since the radial net bar and axial net bar of this creation are constructed by piercing method, once it is pierced, it can be restricted and fixed by the arc frame, and no problem of detachment or damage will occur. [Implementation] In order to allow your reviewers to clearly understand the structural composition of this creation and the functional benefits that can be achieved, the rest are listed in the following examples with illustrations and detailed descriptions as follows: This creation is a descreening screen The structure is improved. The radial meshes 2 in the curved frame 1 are mainly slab screens.

Creation instructions (3) Corresponding to the long through-hole 2 1 (shown in the second figure) corresponding to the center of the arc, so that the axial mesh rod 3 of the long elliptical section can be fixed through it, which can improve the bearing Stress and exfoliative effect.
藉由上述之組成設計，該脫穀篩網1 〇是對應設置於 脫穀筒2 0之外圍並保持一間距（如第三圖所示），所以 當使用者將稻穗經由間距處導入時，稻穗將可被支撐於脫 穀篩網1 0之上而被脫穀筒2 0予以連續拍打，藉由脫穀 篩網1 0的阻抗而促使稻榖得以與稻桿順利分離而落下， 而在此一過程中，由於軸向網桿3是以輻向排列而對應脫 穀筒2 0旋轉中心（如第四圖所示），所以可產生最佳的 線狀接觸以促進稻穗更易受力落下，而且軸向網桿3的設 計不僅可以增進承壓性，更可由軸向網桿3的長橢圓斷面 延長耐磨性，增加使用時間。 再者，本創作於弧形框架1上是佈設有複數補強肋4 ，俾以增進脫榖篩網1〇的整體強度。With the above composition design, the threshing screen 10 is correspondingly arranged on the periphery of the threshing cylinder 20 and maintains a distance (as shown in the third figure), so when the user introduces ears of rice through the distance, The ears of rice can be supported on the threshing screen 10 and be beaten continuously by the threshing tube 20. The resistance of the threshing screen 10 will promote the smooth separation of the indica from the rice straw and fall. In this process, because the axial net rods 3 are arranged in a radial direction and correspond to the rotation center of the threshing cylinder 20 (as shown in the fourth figure), the best linear contact can be produced to promote the ears of rice more easily. The force drops, and the design of the axial net rod 3 can not only improve the pressure bearing capacity, but also can extend the wear resistance and increase the service time by the long oval section of the axial net rod 3. Furthermore, the present invention is provided with a plurality of reinforcing ribs 4 on the curved frame 1 to enhance the overall strength of the dehydration screen 10.
