Description

Technical Field

[0001] The invention relates to the technical field of agricultural residual film recovery, in particular to a device for recovering residual film from potato fields. Background Art

[0002] Residual film recycling is crucial in agriculture because residual mulch film is difficult to degrade. Long-term accumulation will hinder soil aeration and water permeability, affect crop root growth and nutrient absorption, and reduce land productivity. In addition, residual film may be ingested by livestock, causing health problems, or migrate with the wind to cause environmental pollution. Effective recycling of residual film helps maintain the ecological balance of farmland and ensure sustainable agricultural development.

[0003] In the prior art, patent CN 108934228 A discloses a typical residual film recovery device, which has a film picking roller, a residual film conveying and soil removal device and a film collecting box arranged from front to back. In the device, the residual film conveying and soil removal device is a traditional rod chain structure, and the soil removal effect is poor during the conveying process, so that the collected residual film still contains a lot of soil and impurities, which increases the difficulty of subsequent residual film treatment. Patent CN 118715897 A sets a knocking mechanism on the lower side of the rod chain to improve the soil removal effect, but due to the weak knocking effect on the local residual film, the overall soil removal effect is limited. Summary of the invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a potato field residual film recovery device that can enhance the soil removal effect of the residual film by vibration and reduce the soil content in the residual film.

[0005] Technical solution: To achieve the above-mentioned purpose, the potato field residual film recovery equipment of the present invention comprises a frame, on which a film pickup roller, a chain rake mechanism and a collection box are installed; the chain rake mechanism comprises a plurality of chain mechanisms arranged in parallel;

[0006] All the chain mechanisms included in the chain rake mechanism include a first chain mechanism and a second chain mechanism, and the two chain mechanisms are arranged alternately;

[0007] The first chain mechanism comprises a first chain, wherein the first chain has a first high sprocket and a first low sprocket at the high and low ends respectively;

[0008] The second chain mechanism comprises a second chain, and the second chain has a second high sprocket and a second low sprocket at the high and low ends respectively;

[0009] All the first low sprockets and the second low sprockets are staggeredly mounted on the first shaft, and the first low sprockets and the second low sprockets are rotatably mounted relative to the first shaft; all the first high sprockets are mounted on the second shaft, and all the second high sprockets are mounted on the third shaft; the first high sprocket and the second high sprocket are fixedly mounted relative to the second shaft and the third shaft respectively;

[0010] The second shaft and the third shaft are both mounted on a rotating frame, and the rotating frame can perform reciprocating swing motion.

[0011] By adopting the above structure, a first chain mechanism and a second chain mechanism are arranged in an alternating manner, and the low-position sprockets of the two are coaxially installed, and the high-position sprockets of the two are respectively installed on the second shaft and the third shaft. When picking up, the second shaft and the third shaft can be alternately raised by rotating the rotating frame. The two chain mechanisms can beat the residual film transported on the chain rake mechanism, and the further back the residual film is, the greater the beating force on the residual film, so that soil and other impurities on the residual film can be fully removed, so that the collected residual film has less soil and impurities content, which is convenient for subsequent processing.

[0012] Furthermore, the chain rake mechanism further comprises a first motor and a rotating wheel driven by the first motor, the rotating wheel has a pin, the rotating frame has a bar hole, and the pin is placed in the bar hole. In this way, the operation of the first motor can drive the rotating frame to swing back and forth.

[0013] Furthermore, the chain rake mechanism also includes a gear set for establishing a transmission relationship between the second shaft and the third shaft; one of the first chain mechanism and the second chain mechanism is indirectly driven by a PTO output shaft of the tractor.

[0014] Furthermore, the first chain mechanism further includes a first tensioning wheel, and the first tensioning wheels corresponding to all the first chain mechanisms are rotatably mounted on a fourth shaft; and the fourth shaft is connected to the frame via a first elastic tensioning mechanism.

[0015] Furthermore, the second chain mechanism also includes a second tensioning wheel, and the second tensioning wheels corresponding to all the second chain mechanisms are rotatably mounted on a fifth shaft; and the fifth shaft is connected to the frame via a second elastic tensioning mechanism.

[0016] The fourth axis and the fifth axis are staggered so that all the first tensioning wheels and all the second tensioning wheels can be tensioned respectively without interfering with each other.

[0017] Furthermore, anti-skid teeth are fixed at equal distances on all the first chains and all the second chains, and the anti-skid teeth can prevent the residual film from sliding relative to the first chain and the second chain during the conveyance of the residual film.

[0018] Beneficial effects: The potato field residual film recovery equipment of the present invention has the following beneficial effects:

[0019] By arranging the first chain mechanism and the second chain mechanism in an alternating manner, and installing the low-position sprockets of the two coaxially, and installing the high-position sprockets of the two on the second shaft and the third shaft respectively, when performing the picking operation, the second shaft and the third shaft can be alternately raised by rotating the rotating frame, and the two chain mechanisms can beat the residual film transported on the chain rake mechanism, and the further back the residual film is, the greater the beating force on the residual film, so that the soil and other impurities on the residual film can be fully removed, so that the soil content of the collected residual film is less, which is convenient for subsequent processing.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 The potato field residual film recovery equipment comprises a frame 1, on which a film pickup roller 2, a chain rake mechanism 3 and a collection box 4 are installed; the chain rake mechanism 3 comprises a plurality of chain mechanisms arranged in parallel;

[0030] like Figures 2 to 4 As shown, all the chain mechanisms included in the chain rake mechanism 3 include a first chain mechanism 31 and a second chain mechanism 32, and the two chain mechanisms are arranged alternately;

[0031] The first chain mechanism 31 comprises a first chain 31a, wherein the first chain 31a has a first high sprocket 31b and a first low sprocket 31c at the upper and lower ends thereof respectively;

[0032] The second chain mechanism 32 comprises a second chain 32a, and the second chain 32a has a second high sprocket 32b and a second low sprocket 32c at the upper and lower ends thereof respectively;

[0033] All the first low sprockets 31c and the second low sprockets 32c are staggeredly mounted on the first shaft 33, and the first low sprockets 31c and the second low sprockets 32c are rotatably mounted relative to the first shaft 33; all the first high sprockets 31b are mounted on the second shaft 34, and all the second high sprockets 32b are mounted on the third shaft 35; the first high sprockets 31b and the second high sprockets 32b are fixedly mounted relative to the second shaft 34 and the third shaft 35 respectively;

[0034] The second shaft 34 and the third shaft 35 are both mounted on a rotating frame 36 , and the rotating frame 36 can perform reciprocating swing motion.

[0035] By adopting the above structure, a first chain mechanism 31 and a second chain mechanism 32 are arranged in an alternating manner, and the low-position sprockets of the two are coaxially installed, and the high-position sprockets of the two are respectively installed on the second shaft 34 and the third shaft 35. When picking up, the second shaft 34 and the third shaft 35 can be alternately raised by rotating the rotating frame 36. The two chain mechanisms can beat the residual film transported on the chain rake mechanism 3, and the further back the residual film is, the greater the beating force on the residual film, so that soil and other impurities on the residual film can be fully removed, so that the soil content of the collected residual film is less, which is convenient for subsequent processing. Figure 6 A state in which the second chain 32a is higher than the first chain 31a is shown.

[0036] Specifically, the chain rake mechanism 3 further includes a first motor 37 and a rotating wheel 38 driven by the first motor 37. Figure 5As shown, the rotating wheel 38 has a pin 38a, and the rotating frame 36 has a strip hole 36a, and the pin 38a is placed in the strip hole 36a. In this way, the first motor 37 can drive the rotating frame 36 to swing back and forth.

[0037] As shown in the figure, the chain rake mechanism 3 also includes a gear set 39 that establishes a transmission relationship between the second shaft 34 and the third shaft 35; one of the first chain mechanism 31 and the second chain mechanism 32 is indirectly driven by the PTO output shaft of the tractor.

[0038] like Figure 7 As shown, the gear set 39 includes a circular gear set 39a and a non-circular gear set 39b. The second shaft 34 transmits power to the transition shaft 39c through the circular gear set 39a, and the transition shaft 39c transmits power to the third shaft 35 through the non-circular gear set 39b. The number of teeth of the two gears constituting the circular gear set 39a is equal, and the number of teeth of the two non-circular gears constituting the non-circular gear set 39b is also equal; in this way, the operation of the second shaft 34 and the third shaft 35 is asynchronous, which can make the residual film on the chain rake mechanism 3 vibrate parallel to the conveying direction, further increase the vibration of the residual film, and improve the efficiency of shaking off dirt.

[0039] like Figure 1 As shown, the first chain mechanism 31 further includes a first tensioning wheel 310 , and all the first tensioning wheels 310 corresponding to the first chain mechanisms 31 are rotatably mounted on a fourth shaft 311 ; the fourth shaft 311 is connected to the frame 1 via a first elastic tensioning mechanism 312 .

[0040] The second chain mechanism 32 further includes a second tensioning wheel 313 , and all the second tensioning wheels 313 corresponding to the second chain mechanisms 32 are rotatably mounted on a fifth shaft 314 ; the fifth shaft 314 is connected to the frame 1 via a second elastic tensioning mechanism 315 .

[0041] The fourth shaft 311 and the fifth shaft 314 are staggered so that all the first tensioning wheels 310 and all the second tensioning wheels 313 can be tensioned respectively without interfering with each other.

[0042] Preferably, anti-skid teeth 316 are equidistantly fixed on all the first chains 31a and all the second chains 32a. The anti-skid teeth 316 can prevent the residual film from sliding relative to the first chain 31a and the second chain 32a during the conveyance of the residual film.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
