Description

Technical Field

[0001] The utility model relates to the technical field of seed threshing and screening, in particular to a corn seed threshing and screening machine. Background Art

[0002] Corn seeds are very important crop seeds in agricultural production. They are developed from the ear part of corn plants, have high nutritional value and wide uses. Corn seeds can not only be used as a food source for humans, but also as animal feed, and also have important applications in industrial production, such as the production of biofuels.

[0003] There is a Chinese patent with the publication number CN214430290 and the name of a corn seed threshing and screening machine, which includes a chassis. Both sides of the chassis are symmetrically fixedly connected with side support plates. A threshing box is fixedly installed at the top of the chassis. A threshing mechanism is installed in the threshing box. The threshing mechanism includes a rotating cylinder and a peeling cylinder. The rotating cylinder and the peeling cylinder are both installed on one side close to the inside of the threshing box. The rotating cylinder and the peeling cylinder are symmetrically arranged up and down. A number of peeling blocks are fixedly connected to the peeling cylinder. The beneficial effect of the utility model is that the threshing box is designed to be inclined. Using inertia, orderly feeding is carried out through the feeding plate, and the corn cobs are orderly fed through the feeding plate. The motor drives the rotating cylinder and the peeling cylinder to rotate. The rotating cylinder conveys the corn, and the peeling cylinder peels the corn kernels on the surface of the corn. The corn kernels are orderly fed through the discharge port of the discharge box. The discharge box is driven by a vibrator to vibrate, effectively avoiding the occurrence of material jamming. This patent only realizes the threshing function of corn and lacks the screening of corn seeds, which will cause the impurities remaining in the corn seeds to affect subsequent storage, and further affect the sowing quality of corn seeds. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to provide a corn seed threshing and screening machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A corn seed threshing and screening machine includes a base. An obliquely placed U-shaped frame is arranged above the base. A vibration mechanism is connected between the high end of the U-shaped frame and the base. A support mechanism is connected between the low end of the U-shaped frame and the base. A threshing machine is arranged on one side of the high end of the U-shaped frame. A feed chute is fixedly connected through the side wall of the threshing machine and is communicated with it. The end of the feed chute far from the threshing machine is located inside the high end of the U-shaped frame. A collection cart is arranged on one side of the low end of the U-shaped frame. A screen is arranged at the inner bottom of the U-shaped frame. A collection mechanism is arranged below the screen. The collection mechanism is connected to the U-shaped frame. A vibration motor is fixedly connected to the bottom of the high end of the U-shaped frame.

[0007] As a further improvement of the present utility model, the vibration mechanism includes a fixed column fixedly connected to the top of the base, a vibration spring fixedly connected to the top of the fixed column, a fixed block fixedly connected to the end of the vibration spring away from the fixed column, and the fixed block is fixedly connected to the outer wall of the U-shaped frame.

[0008] As a further improvement of the present utility model, the support mechanism includes a support column fixedly connected to the top of the base, and a rotating shaft is connected between the upper end of the support column and the U-shaped frame.

[0009] As a further improvement of the present utility model, the collection mechanism includes a collection box fixedly connected to the bottom of the U-shaped frame, a bottom of the collection box is grooved and fixedly connected with a fixed frame, one side of the fixed frame is open and both ends are rotatably connected with fixed buckles, an impurity box is slidably arranged inside the fixed frame, the impurity box is connected to the fixed frame through the fixed buckles, and a handle is fixedly connected to one side of the impurity box.

[0011] As a further improvement of the present utility model, four universal wheels are provided at the bottom of the collection cart.

[0012] Advantages of the present utility model:

[0013] By setting the vibration mechanism and the support mechanism, the vibration force generated by the up and down vibration of the vibration motor causes the U-shaped frame to vibrate under the action of the vibration spring and the support mechanism, and the corn seeds in the U-shaped frame vibrate accordingly, so that the impurities attached to the corn seeds fall off, which can effectively improve the quality and sowing effect of the corn seeds.

[0014] By setting the collection mechanism and the fixed frame, the impurities falling off from the corn seeds can fall through the sieve mesh arranged at the bottom inside the U-shaped frame into the collection box. Since the collection box and the U-shaped frame are arranged obliquely, the impurities can slide into the impurity box in the collection box. At the same time, the impurity box is located inside the fixed frame. By rotating and opening the fixed buckles, the impurity box can be taken out through the handle, realizing the automatic collection and separation of impurities in the seeds and facilitating the subsequent cleaning work of the impurities.

[0015] Through the coordinated action of the vibration mechanism and the collection mechanism of the present utility model, the automatic falling off, collection and separation of impurities in corn seeds are realized, which not only improves the quality of corn seeds, but also improves the working efficiency.

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Figures 1 - 3 A corn seed threshing and sieving machine includes a base 1. The base 1 is of a rectangular structure. Above the base 1, there is an obliquely placed U-shaped frame 7. A vibration mechanism is connected between the high end of the U-shaped frame 7 and the base 1. The vibration mechanism includes a fixing column 2 fixedly connected to the top of the base 1. The contact surface between the fixing column 2 and the base 1 is welded. The top of the fixing column 2 is fixedly connected to a vibration spring 3. The end of the vibration spring 3 away from the fixing column 2 is fixedly connected to a fixing block 4. The fixing block 4 is fixedly connected to the outer side wall of the U-shaped frame 7. The contact surface between the fixing block 4 and the U-shaped frame 7 is welded. A support mechanism is connected between the low end of the U-shaped frame 7 and the base 1. The support mechanism includes a support column 11 fixedly connected to the top of the base 1. The support column 11 is fixedly connected to the base 1 by bolts. A rotating shaft 10 is connected between the upper end of the support column 11 and the U-shaped frame 7. On one side of the high end of the U-shaped frame 7, there is a threshing machine 5. The side wall of the threshing machine 5 penetrates and is fixedly connected to a feeding inclined port 6 communicating with it. The end of the feeding inclined port 6 away from the threshing machine 5 is located inside the high end of the U-shaped frame 7. On one side of the low end of the U-shaped frame 7, there is a collection cart 13. The bottom of the collection cart 13 is provided with four universal wheels. A sieve mesh 17 is provided at the inner bottom of the U-shaped frame 7. The sieve mesh 17 is made of stainless steel. A collection mechanism is provided below the sieve mesh 17. The collection mechanism is connected to the U-shaped frame 7. A vibration motor 9 is fixedly connected to the bottom of the high end of the U-shaped frame 7.

[0022] The collection mechanism includes a collection box 8 fixedly connected to the bottom of the U-shaped frame 7. The collection box 8 and the U-shaped frame 7 are both obliquely placed. The bottom end of the collection box 8 is grooved and fixedly connected with a fixed frame 12. The top and one side of the fixed frame 12 are open. The size of the groove at the bottom end of the collection box 8 is smaller than the opening at the top of the fixed frame 12. Both ends of the side opening of the fixed frame 12 are rotatably connected with fixed buckles 15. An impurity box 14 is slidably arranged inside the fixed frame 12. The impurity box 14 is connected to the fixed frame 12 through the fixed buckles 15. A handle 16 is fixedly connected to one side of the impurity box 14.

[0023] When the utility model is in use, the worker puts the corn into the thresher 5, and then starts the thresher 5. The thresher 5 transports the threshed corn seeds to the inside of the U-shaped frame 7 through the feeding inclined opening 6. Then, the vibration motor 9 is started. The vibration force generated by the up-and-down vibration of the vibration motor 9 causes the U-shaped frame 7 to vibrate under the action of the vibration spring 3 and the support mechanism. The corn seeds in the U-shaped frame 7 vibrate accordingly, so that the impurities attached to the corn seeds fall off. The fallen impurities fall onto the collection box 8 through the screen 17 arranged at the inner bottom of the U-shaped frame 7. Since the collection box 8 and the U-shaped frame 7 are both obliquely placed, the impurities can slide into the impurity box 14 in the collection box 8. At the same time, the impurity box 14 is located inside the fixed frame 12. By rotating and opening the fixed buckles 15 at both ends of the fixed frame 12, the impurity box 14 can be taken out through the handle 16. The corn seeds after sieving are transported downward into the collection vehicle 13 along with the vibration of the U-shaped frame 7.
