Description

Technical Field

[0001] The utility model relates to an agricultural machine, namely a pepper anti-blocking picking machine. Background Art

[0002] The harvesting process of large-scale peppers is time-sensitive, with a large workload and great difficulty in manual operation. The demand for mechanization is particularly urgent. To this end, I have developed a variety of pepper pickers. This type of pepper picker is equipped with a crushing bin and a screener. When working, the pepper plants are first cut down and dried, and when the stems are dry, the whole plant is put into the crushing bin for crushing. Since the stems become more brittle after drying and are easy to crush, while the peppers become more tough and not easy to break, the peppers can be separated from the stems by crushing. Then they enter the screener, the finely crushed stems are screened out, and the peppers flow out from the outlet at the rear end of the screener. However, the outlet at the rear end of the screener has no forced conveying device and moves only by the weight of the peppers, which is easy to block. After the blockage, it is often necessary to stop the machine for processing, which reduces the operating efficiency of the machine and even violates the farming season and causes losses. In particular, after the operator finds the blockage, in order to troubleshoot the fault as soon as possible, he often takes out the blocked material. This is very unsafe and prone to injuries. Summary of the invention

[0003] The utility model aims to develop a pepper picking machine which can complete the crushing and screening operations of peppers and stems, has smooth material flow, is not easy to be blocked, has high operating efficiency, good safety, and can not cause injuries.

[0004] The above-mentioned purpose is achieved by the following technical scheme: a pepper anti-blocking picking machine is provided, including a feeder, a crushing bin, and a sifter. The sifter is cylindrical, and the cylinder wall is surrounded by a plurality of slender slats. There are slits between adjacent slats for screening out stems and retaining peppers. The sifter is characterized in that: the sifter is placed flat on the frame and supported by rotatable rollers on both sides of the frame, wherein the roller on one side is an active roller, and the roller on the other side is a driven roller, and the active roller can rotate under the drive shaft. , and can drive the screener to rotate; the rear section of the cylindrical screener is provided with a plurality of inverted sheets, which are installed along the radial direction of the cylinder, and the outer end is connected to the inner wall of the cylinder. The rear end of the screener is closed by a thin plate, and a discharge port is opened in the middle of the thin plate. A collecting belt is installed on the discharge port. The front and rear ends of the collecting belt are supported by a rotating shaft, and the rotating shaft is installed on the frame outside the screener through a bracket. One of the rotating shafts is driven by the power machine, and the front end of the collecting belt extends into the discharge port of the screener and is opposite to each inverted sheet. When working, the peppers flowing to the rear end of the cylinder are lifted by the inverted sheet and put on the collecting belt for delivery.

[0005] The collecting conveyor belt is provided with a plurality of scrapers extending outwards.

[0006] The scraper is composed of a plurality of fine teeth.

[0007] The slats on the periphery of the sieve cylinder have a triangular cross-section, with one sharp corner facing the axis direction of the cylinder.

[0008] A lifter is installed at the rear end of the frame. The front side and the left and right sides of the lifter are sealed by windshields. There is a feed inlet at the lower section of the front windshield. The upper part of the feed inlet faces the collecting conveyor belt. The lower end of the lifter is hinged to the frame. There is a lifting belt inside the lifter. The two ends of the lifting belt are supported by rotating shafts. The rotating shaft at the lower end is driven by a power machine. There are multiple lifting plates outside the lifting belt.

Detailed implementation mode

[0024] The general concept of the present utility model is: to install a device with forced conveying performance on the sieve of the chili picking machine to avoid blockage. The following introduces an embodiment in conjunction with the attached drawings:

[0025] Figs. 1 and 2 illustrate a chili anti-blocking picking machine. In the order shown in the figures, there are a feeder 1, a crushing bin 2 and a sieve 3 in sequence. The above-mentioned mechanisms are all installed on a frame 6, and walking wheels are provided under the frame. A power machine 7 is installed at the front of the frame. The power machine can be a diesel engine.

[0026] The said feeder is also called a picker, and a conveyor belt is arranged inside. When in use, the chili plants that have been cut and sun-dried for a period of time are put into the feeder and pushed backward and upward through the conveyor belt into the subsequent crushing bin. After the stems of the plants are sun-dried, their brittleness increases and they are easy to crush. While the chili peppers after sun-drying have enhanced toughness and are not easy to break. Therefore, after passing through the crushing bin, the chili peppers can be separated from the stems. Then the chili peppers and the stems are put into the subsequent sieve, and the stems are sifted out, and the chili peppers can be screened out.

[0027] Generally speaking, a chili collecting device should be equipped behind the sieve. Currently, the more commonly used chili collecting device is a lifter 4 and a vehicle. After the lifting conveyor lifts the chili peppers to a certain height, they are put into the carriage. This vehicle can also be used to tow the chili picking machine.

[0028] As can be seen in the figure, behind the sieve and in front of the lifter, there is a collecting conveyor 5. The collecting conveyor 5 is in the shape of a conveyor belt and can convey the chili peppers in the sieve to the subsequent chili collecting device. Compared with the existing collecting device that relies on the gravity of the chili peppers to flow out by itself, the collecting conveyor has a certain forced conveying effect on the chili peppers, so it is not easy to be blocked.

[0029] Obviously, there can be various structural forms of the foregoing device. The following lists several preferred forms.

[0030] Combined with Figs. 3 and 4, it can be seen that the sieve 3 is in a cylindrical shape, and the barrel wall of the cylinder is surrounded by a plurality of long slats 8. The sieve slots 9 between the slats can sieve out the crushed stems, while the volume of the chili peppers is relatively large and cannot be sieved out, and can only flow to the end of the sieve.

[0031] Obviously, the shape of the slats can be various. The cross-section of the slat 8 illustrated in Fig. 3 is rectangular, which is relatively simple and has good inner sliding performance.

[0032] Fig. 4 illustrates another shape of the slat 8. The cross-section of the slat is triangular, with one sharp corner facing the axis direction of the cylinder. The inner sieve slots of this kind of slat are larger, making it easier for materials to enter and the screening of stalks more thorough.

[0033] As can be seen from Figs. 5 and 6, there are multiple deflector plates 13 arranged in the rear section inside the screening cylinder. The simplest deflector plate is made of a rectangular thin plate, shaped like a 16 - opening paper sheet, and installed along the radial direction of the cylinder. The outer end of the deflector plate can be connected to the inner wall of the cylinder through two mounting rings 15. Since the mounting rings are relatively narrow, the sealing area for the sieve slots is very small.

[0034] As can be seen from the figure, the rear end of the screening device is closed by a thin plate, and a discharge port 14 is opened in the middle of the thin plate. A collecting and conveying belt 5 is installed at the discharge port.

[0035] Figs. 7 and 8 further show the installation method of the collecting and conveying belt 5. As can be seen from the figure, the collecting and conveying belt 5 is installed between the cylindrical screening device 3 and the elevator 4.

[0036] The cylindrical screening device 3 is placed flat on the upper surface of the frame 6 and supported by the idler rollers on both sides of the frame. One of the idler rollers is the driving idler roller 11, and the other is the driven idler roller 12. The diesel engine drives the driving idler roller 11 on one side of the frame to rotate through a transmission shaft 10, thereby enabling the screening device to rotate. For the sake of easy understanding, the screening device 3 in Fig. 8 is represented by a phantom line.

[0037] The elevator 4 is equipped with windshields 18 on the front side and both left and right sides, which can prevent the wind from blowing the materials. The lower section of the front windshield is provided with a feed inlet 19, and the upper part of the feed inlet is opposite to the collecting and conveying belt. The lower end of the elevator is hinged to the frame and can be supported by ropes or hydraulic cylinders, and the inclination angle is adjustable. There is a lifting belt 16 inside the elevator, and both ends of the lifting belt are supported by rotating shafts. The lower rotating shaft is driven by a power machine, and multiple lifting plates 17 are arranged outside the conveyor belt.

[0038] In the figure, both the front and rear ends of the collecting and conveying belt 5 are supported by rotating shafts, and the rotating shafts are installed on the frame outside the screening device through brackets. The front end of the collecting and conveying belt extends into the discharge port of the screening device and is opposite to each deflector plate on the cylinder wall. One of the rotating shafts of the collecting and conveying belt is preferably driven by a power machine through the rotating shaft outside the screening device. During operation, the peppers flowing to the rear end of the cylinder are lifted by the deflector plates. After reaching above the collecting and conveying belt, the angle of the deflector plates flips, and the peppers can be dropped onto the collecting and conveying belt and sent out along with the collecting and conveying belt.

[0039] There are also many structural forms of the collecting and conveying belt. Figures 9, 10, and 11 respectively illustrate three kinds of collecting and conveying belts: as shown in Figure 9, the collecting and conveying belt is in a flat plate shape. This structure is relatively simple. After rotation, the peppers are pushed out by the friction on the surface of the flat belt.

[0040] As shown in Figure 10, a plurality of outwardly convex scraping plates 20 are installed on the surface of the collecting and conveying belt. After rotation, it can better drive the peppers to move outward, and the coercive performance is prominent.

[0041] As shown in Figure 11, the scraping plate on the collecting and conveying belt is composed of a plurality of fine teeth 21. The fine teeth can be made of materials such as steel wires or plastic rods with a certain elasticity, which are coercive to the materials and are relatively simple and light.

[0042] Experiments have proved that the pepper picker adopting the above mechanism has a high pepper separation rate, thorough screening of the stalks, and good material fluidity. Especially at the outlet of the sieve, the peppers move smoothly and are not easily blocked, thus solving the problems of poor material flow and easy blockage of the existing equipment.
