Abstract

The utility model relates to a settable floating root cutting system device which is suitable for a section cutting type cane harvesting machine so as to improve the root cutting operation precision and avoid damage to perennial roots. The device comprises a control module, and the control module comprises an executing mechanism, a cutter head height adjusting program and an information collecting module. The information acquisition module is used for acquiring the height (a) of the cutter head relative to the chassis and the height (b) of the front part of the chassis relative to the ground in real time, calculating the actual height (z = b-a) of the cutter head relative to the ground, and setting the allowable floating range of z. And the cutter head height adjusting program judges whether z is in an allowable floating range according to the information acquisition result, and if not, the executing mechanism adjusts the height of the cutter head to enable z to be recovered to be in the allowable range. If z is a negative number, the cutterhead ascends; and if z is a positive number, the cutterhead descends. The process is continuously carried out until the height of the cutter head is stable.

Description

Technical Field

[0001] This invention relates to a configurable floating root cutting system device. Background Technology

[0002] Due to their strong adaptability and high efficiency, sugarcane harvesters have become the mainstream machinery in sugarcane harvesting. These machines, through multiple functions such as cutting, peeling, and root cutting, greatly improve the efficiency of sugarcane harvesting and promote mechanized sugarcane production. However, some problems still need to be solved in the use of existing sugarcane harvesters, especially in the root cutting operation.

[0003] In existing technologies, the height of the root cutter is usually adjusted manually by the operator to adapt to different terrain conditions. Due to the significant variations in terrain and the lack of a standardized height adjustment method, coupled with the inherent delay in manual adjustment, the root cutter often cuts too deeply, penetrating the ratoon layer and damaging the sugarcane's root system. Damage to the ratoon not only affects subsequent sugarcane growth but also reduces production efficiency. Therefore, effectively preventing the root cutter from cutting into the ratoon has become one of the challenges in promoting mechanized sugarcane harvesting.

[0004] Furthermore, current sugarcane harvesters using the segmented harvesting method still suffer from high impurity rates and significant losses. During the harvesting process, in addition to sugarcane, other weeds or non-target plants often mix in, resulting in high impurity content. Excessive losses not only reduce the sugarcane harvesting rate but also increase harvesting costs, further hindering the widespread adoption of mechanized harvesting.

[0005] These two types of problems, especially the risk of the root cutter cutting into the ratoon, seriously affect the effectiveness and economic benefits of mechanized harvesting. To avoid damaging the ratoon, many farmers usually choose to use machinery for harvesting in the third year of sugarcane planting. Although this practice can reduce damage to the ratoon, it leads to inefficient use of machinery and equipment, preventing its wider application.

[0006] Although existing technologies allow for manual adjustment of the cutting blade height to adapt to different terrains and enable operators to monitor the blade height in real time during operation, this method still cannot effectively prevent damage to the rootstock. Therefore, a more precise and intelligent technical solution is urgently needed that can ensure efficient operation while avoiding damage to the rootstock, thus providing technical support for the widespread adoption and application of segmented sugarcane harvesters. Utility Model Content:

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a configurable floating root cutting system device.

[0008] A configurable floating root cutting system includes a control module, which comprises an actuator, a cutter head height adjustment program, and an information acquisition module. The information acquisition module is used to collect in real time the height 'a' of the cutter head relative to the chassis, and the height 'b' of the chassis at the front position of the cutter head relative to the ground. The actuator is used to adjust the height of the cutter head. The cutter head height adjustment program executes the following steps in real time based on the information collected by the information acquisition module:

[0009] Step 1: Set the initial value of 'a' to obtain the actual height z of the cutter head relative to the ground in front of it, z = ba, and set the allowable floating range of z;

[0010] Step 2: Determine the relationship between z and the allowable floating range. If z is within the allowable floating range, maintain the height of the cutter head. If z exceeds the allowable floating range, control the actuator to adjust the height of the cutter head. Specifically, if z is negative, the cutter head rises; if z is positive, the cutter head falls.

[0011] Step 3: After adjustment, repeat step 2 until z is within the allowable fluctuation range.

[0012] Furthermore, the actuator is a linear telescopic hydraulic cylinder.

[0013] Furthermore, the information acquisition module includes a pressure sensor and a displacement sensor.

[0014] Furthermore, the pressure sensor is connected to the oil chamber of the hydraulic cylinder.

[0015] Furthermore, the displacement sensor is a contact sensor.

[0016] Furthermore, the component of the contact sensor that comes into contact with the ground is a roller.

[0017] Furthermore, the absolute value of the vertical z-axis for adjusting the cutter head height.

[0018] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0019] To avoid cutting off rootstock and protect the soil: The system monitors the height of the cutter head relative to the ground in real time and automatically adjusts the height of the cutter head according to changes in ground level, precisely preventing the cutter head from sinking excessively to an unsuitable position. This ensures the cutter head remains at a reasonable height, avoiding accidental cutting of rootstock, protecting the root structure of the soil, and contributing to maintaining the ecological balance of the soil and crop growth.

[0020] Precise adjustment of the cutter head height improves operational accuracy: The information acquisition module can acquire the height difference between the cutter head and the chassis in real time, and accurately calculate the height change of the cutter head based on this information, ensuring that the cutter head can flexibly cope with ground undulations. During the root cutting process, the system can accurately set the cutter head height in the early stages of the operation, ensuring that the root cutting quality is not affected by improper height settings, thereby improving the overall operational accuracy.

[0021] Avoiding unnecessary losses and equipment wear: By avoiding cutting off the rootstock, not only are unnecessary crop losses in agricultural production effectively reduced, but equipment wear and damage are also minimized. Excessive contact between the cutter head and the rootstock can damage the cutter head and even affect the overall performance of the machine. The system's height adjustment function can reduce this risk and extend the equipment's lifespan.

[0022] Adaptable to different terrains and ensuring operational safety: In complex or uneven terrain, the cutter head height adjustment can automatically adapt to changes, ensuring that the cutter head is always at the appropriate working height. Especially in undulating terrain, it can prevent the cutter head from penetrating too deeply into the ground and cutting into old or immature plant roots that should not be removed.

[0023] Improved work efficiency and energy saving: The system's automated adjustment function can respond in real time during operation, reducing the time and effort required for manual adjustments, thereby improving work efficiency. At the same time, precise control of the cutter head height reduces unnecessary operations, thus improving work efficiency and saving energy. Attached Figure Description

[0027] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0028] This embodiment provides a configurable floating root cutting system, which is mainly used to ensure that the cutter head is always kept within a suitable height range relative to the ground during the root cutting operation by adjusting the height of the cutter head, so as to achieve precise operation control.

[0029] The floating root cutting system includes a control module, which consists of an actuator 2, a cutter head height adjustment program, and an information acquisition module. The information acquisition module collects real-time data on the height of the cutter head relative to the chassis (denoted as 'a') and the height of the chassis relative to the ground from its position in front of the cutter head (denoted as 'b'). Based on this data, the actuator 2 automatically adjusts the cutter head height according to the cutter head height adjustment program.

[0030] In the specific implementation process, the initial height of the cutter head relative to the ground is first set, and the actual height difference between the cutter head and the ground in front is calculated (denoted as z). This actual height z is calculated using the formula z = ba, where the value of z represents the actual height between the cutter head and the ground. This value allows setting the allowable fluctuation range of the cutter head height, ensuring that the cutter head height is always within an appropriate range and avoiding impacts on work efficiency due to excessively high or low heights.

[0031] When the actual height z of the cutter head exceeds the set floating range, actuator 2 will automatically adjust the height of the cutter head according to the instructions of the cutter head height adjustment program. For example, when the z value is negative, it means that the cutter head is too far from the ground and needs to be raised; conversely, when the z value is positive, it means that the cutter head is too close to the ground and needs to be lowered. Actuator 2 makes corresponding adjustments based on this judgment.

[0032] The adjustment process continues until the height z of the cutter head falls back into the allowable fluctuation range. The entire process is monitored in real time by the information acquisition module, and the actuator 2 provides continuous feedback adjustments to ensure that the height of the cutter head remains stable within the required operating range.

[0033] In this embodiment, the actuator 2 is a linear telescopic hydraulic cylinder. The extension and retraction of the cylinder is achieved by controlling the hydraulic pressure, which can precisely adjust the height of the cutter head. The information acquisition module includes a pressure sensor and a displacement sensor 1. The former is connected to the oil chamber of the cylinder and is used to measure the pressure inside the cylinder, thereby reflecting the extension and retraction state of the cylinder; the latter is a contact sensor installed on the cutter head, which can sense the displacement and height changes of the cutter head in real time to ensure precise height adjustment.

[0034] To ensure measurement accuracy, displacement sensor 1 is a contact sensor, and the part in contact with the ground is a roller. The roller design helps to smoothly sense changes in ground height and avoid errors caused by uneven ground.

[0035] During implementation, the adjustment accuracy of the cutter head height is crucial. Therefore, the system strictly controls the absolute value of the z-value to ensure that the change in cutter head height is always within the set allowable range, so as to avoid excessive fluctuations in the cutter head height during operation.

[0036] This precise height control system can effectively improve the efficiency and quality of root cutting operations and avoid operational malfunctions or damage caused by inappropriate cutter head height.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
