Description

Technical Field

[0001] The invention belongs to the technical field of seed unpacking machines, and in particular relates to a high-efficiency seed unpacking machine and an unpacking method. Background Art

[0002] Seed unpacking machine is a kind of high-efficiency mechanical equipment specially designed for unpacking bagged seed materials. It can realize automatic operation, thus significantly improving the efficiency and accuracy of unpacking, while reducing labor costs and labor intensity. Seed unpacking machine usually has automatic functions, which can unpack bagged seeds quickly and accurately; seed unpacking machine is widely used in agriculture, seed industry and other fields. In the agricultural field, it can help farmers unpack and process a large amount of seed materials quickly, providing strong support for subsequent sowing work; in the seed industry, seed unpacking machine has become an important tool to improve production efficiency and reduce costs. Its automatic operation reduces the intensity of manual labor and reduces the errors and safety hazards that may occur during manual unpacking. The equipment can quickly process a large number of bagged seeds, greatly improving production efficiency.

[0003] In the current seed unpacking process, high-speed rotating blades are widely used to break the bags containing seeds. This method uses the sharp edge of the blade and the kinetic energy of rapid rotation to quickly and accurately cut the bag, so that the seeds in the bag can be released; however, after the bag is broken, there are some problems in the seed discharge process. Although most seeds can fall naturally under the action of gravity, the overall discharge efficiency is not high, especially the seeds in the two sides of the bag. Since their position is more remote than the rotary cutting blade, the discharge speed is obviously slower, and such problems are more prominent when the seeds are unevenly distributed inside the bag. The seeds in some areas can be discharged quickly, while other areas may be discharged slowly due to seed accumulation or sparse distribution. This unbalanced discharge phenomenon not only affects the overall efficiency of the unpacking operation, but may also cause unnecessary troubles to the subsequent seed processing links.

[0011] As a preferred technical solution in the present invention, the knocking member includes an eccentric shaft and connecting shafts installed at both ends of the eccentric shaft, wherein the connecting shaft at one end extends to the inner wall of the body, and the two are rotatably connected; a main motor is also fixedly provided on the outside of the body, and the main motor is transmission-connected to the connecting shaft at the other end, and the connecting shaft is driven by the main motor, which in turn drives the eccentric shaft to rotate. Since the eccentric shaft is eccentrically arranged, the purpose of intermittent knocking on the packaging bag can be achieved.

[0012] As a preferred technical solution in the present invention, the cutting piece includes a cutting blade with a shaft rotatably installed inside the machine body, and a driving motor is also installed on the outside of the machine body. The driving motor is transmission-connected to one end of the cutting blade with the shaft, and the cutting blade with the shaft is driven by the driving motor to rotate at a high speed to achieve cutting of the packaging bag.

By passing one end of the transmission shaft through the outside of the machine body and installing a gear at its end, a gear is set at the output end of the driving motor, and a chain is used to achieve the gear connection with the end of the transmission shaft, so that a single motor and a gear transmission group can achieve dual-axis operation.

[0013] As a preferred technical solution in the present invention, a feed conveyor belt and a bag discharge conveyor belt are respectively provided at the feed port and the bag outlet of the machine body, and both are in the same plane as the feed port and the bag outlet of the machine body, so as to facilitate the transportation of the packaging bags with seeds into the machine body and the output of the crushed bags.

[0014] The present invention also discloses an unpacking method of an efficient seed unpacking machine, including a seed unpacking machine, and the specific unpacking steps are as follows:

[0015] Step 1: manually carry the packaging bag containing seeds to the feeding conveyor belt, and then transfer it to the feeding port of the machine body through the feeding conveyor belt;

[0016] Step 2: With the rotation of the transmission shaft, the packaging bag entering the body is continuously transmitted through the belt. At the same time, the cylinder and the double-output shaft reduction motor are started, and the transverse rod is horizontally inserted into the packaging bag. When the transverse rod moves horizontally toward the packaging bag, the push plate will drive the load-bearing plate and the lifting member to move synchronously, that is, the horizontal positions of the vertical rod and the transverse rod remain unchanged. After the transverse rod is inserted into the packaging bag, the I-shaped plate drives the vertical rod to drop synchronously under the action of the lifting member and inserts it vertically into the packaging bag. At this time, the insertion clamping of both sides of the packaging bag is realized. In order to ensure the stable insertion of the packaging bag, the double-output shaft reduction motor drives the transmission bevel gear at the top of the connecting rod to rotate through the bevel gear at the end, and then the transmission bevel gear at the bottom of the connecting rod drives the driving bevel gear to rotate, so as to achieve the purpose of rotating the main screw. The slider will drive the entire opening assembly to move synchronously with the packaging bag under the drive of the main screw.

At this time, the two sides of the packaging bag will be pulled toward the inner wall of the machine body respectively, so as to increase the gap broken by the cutting piece. The main motor drives the connecting shaft and then drives the eccentric shaft to rotate to achieve the purpose of intermittent knocking of the packaging bag. The two cooperate to achieve rapid material discharge. During this period, when seeds splash during the unpacking process, the seeds are separated from the main screw rod and the limit rod through the cover plate protection to avoid adhesion to the surface and affect normal transmission. Some seeds are splashed into the space between the support component and the inner wall of the machine body due to inertia or mechanical movement. At this time, the seeds will fall into the guide trough through the strip groove, and then fall into the discharge hopper from the guide trough to achieve collection;

[0018] Step 4: After the seeds in the packaging bag are unloaded, the vertical rod will be lifted to the initial position by the servo motor and the transmission screw and separated from the packaging bag. Then the horizontal rod will continue to retract to the initial position and separate from the packaging bag. The whole process is completed in the main screw area between the two mounting blocks.

[0019] Step 5: The finished packaging bags are conveyed by belts to the bag discharge conveyor belt for discharge, and the seeds are discharged from the discharge hopper.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, when the packaging bag containing seeds enters the unpacking machine, it can be fixed by staggered insertion of the horizontal insertion rods and the vertical insertion rods on the opening mechanism, and when cutting, the opening mechanism further performs a retraction action to pull the packaging bag toward the inner walls on both sides of the machine body, which not only significantly expands the area of ​​the cut opening, but also effectively reduces the retention of seeds in the packaging bag, thereby greatly improving the feeding speed. When the packaging bag is opened by the opening mechanism, the eccentric shaft driven to rotate by the servo motor will knock on the top area of ​​the packaging bag, fully stimulating the fluidity of the seeds inside the packaging bag. Through this knocking mechanism, the seeds in the packaging bag are more efficiently promoted to be discharged, significantly reducing the blocking phenomenon in the discharge process, and ensuring a significant increase in the discharge speed;

[0022] 2. The protective component designed by the present invention solves the problem of unexpected contact between seeds and the main screw during the unpacking process, ensures the efficiency and smoothness of the unpacking operation, and can isolate the seeds from the main screw during the unpacking process to prevent the seeds from sticking to the main screw and affecting the normal movement. During the unpacking process, some seeds may splash into the space between the propping mechanism and the inner wall of the machine body due to inertia or mechanical movement. Traditional treatment methods often make it difficult to completely remove these residual seeds, which leads to accumulation inside the machine body, affecting the cleanliness of the equipment and subsequent operation efficiency. The protective component designed by the present invention, through its unique reflux mechanism, can automatically guide the seeds splashed to unexpected areas to flow back into the discharge hopper, which not only ensures that the seeds will not remain inside the machine body, avoiding potential pollution and waste, but also further improves the continuity and efficiency of the unpacking operation.

[0041] The machine body 100 has a feed inlet at one end and a bag outlet at the other end, and a discharge hopper 104 is installed at the bottom of the machine body 100. During the unpacking operation, the packaging bag containing seeds is input through the feed inlet, and after being cut by the cutting member, the seeds fall down and are discharged from the discharge hopper 104, and the packaging bag without seeds is discharged from the bag outlet;

[0042] The cutting piece is located inside the machine body 100 and arranged near the feed inlet of the machine body 100, so as to quickly cut the packaging bag containing seeds;

[0043] An expansion mechanism is also provided inside the body 100, and the expansion mechanism includes:

[0044] The expansion assembly 600 is provided in multiple groups and symmetrically placed on the side wall of the body 100;

[0045] The walking assembly is installed inside the machine body 100; the opening assembly 600 is fixed on the walking assembly and moves back and forth in a straight line with the walking assembly;

[0046] The expansion assembly 600 includes a cylinder 601 that is horizontally retracted in the vertical direction of the feed, and a push plate 602 is installed on the output end of the cylinder 601. A horizontal insertion rod 604 is fixed on the outer end surface of the push plate 602. When the packaging bag containing seeds enters the body 100, the cylinder 601 will be horizontally inserted into the packaging bag.

The cylinder 601 is installed on the top of the slider 506. After the expansion assembly 600 completes the insertion limitation of the packaging bag, and during the expansion movement, the slider 506 will drive the entire expansion assembly 600 to move synchronously with the packaging bag, so as to avoid the phenomenon that the packaging bag is always at the feed port of the machine body 100, and to move with the packaging bag.

In order to ensure the stable insertion of the packaging bag, the double-output shaft reduction motor 301 drives the transmission bevel gear 304 at the top of the connecting rod 302 to rotate through the bevel gear at the end, and then the transmission bevel gear 304 at the bottom of the connecting rod 302 drives the driving bevel gear 503 to rotate, so as to achieve the purpose of rotating the main screw rod 502, and the slider 506 will drive the entire opening assembly 600 to move synchronously with the packaging bag under the drive of the main screw rod 502;

[0060] Step 3: When the package is cut by the cutting piece, the cylinder 601 retracts, and the main motor 401 is also started synchronously. The cylinder 601 drives the horizontal insertion rod 604 and the vertical insertion rod 606 to move synchronously. At this time, the two sides of the packaging bag will be pulled toward the inner wall of the body 100 respectively, so as to increase the gap broken by the cutting piece, and the main motor 401 drives the connecting shaft 403, and then drives the eccentric shaft 402 to rotate, so as to achieve the purpose of intermittent knocking of the packaging bag. The two cooperate to achieve rapid discharge. During this period, when seeds splash during the unpacking process, the cover plate 504 is used to protect the seeds, separate the seeds from the main screw rod 502 and the limit rod to avoid adhesion to the surface and affect normal transmission. Some seeds splash into the space between the support component 600 and the inner wall of the body 100 due to inertia or mechanical movement. At this time, the seeds will fall into the guide groove 107 through the strip groove 505a, and then fall into the discharge hopper 104 from the guide groove 107, so as to achieve collection;

[0061] Step 4: After the seeds in the packaging bag are unloaded, the vertical rod 606 is lifted to the initial position by the servo motor 608 and the transmission screw 609 and separated from the packaging bag, and then the horizontal rod 604 is further retracted to the initial position and separated from the packaging bag. The whole process is completed within the interval of the main screw 502 between the two mounting blocks 501;

[0062] Step 5: The finished packaging bags are transported by the belt 106 to the bag discharge conveyor belt 202 for discharge, and the seeds are discharged from the discharge hopper 104 .
